Detailed Description
The invention discloses a switch capable of remotely storing energy and performing opening and closing operations, which belongs to a miniature and intelligent isolating switch with the capability of rapidly opening.
The invention will be described in further detail with reference to the drawings and specific embodiments, but it should not be construed that the scope of the invention is limited to the embodiments described below.
1 System scheme
Referring to fig. 1, there is shown a system structure of the isolating switch of the present invention, which has a plurality of functional mechanisms, specifically including a contact system and a contact position detecting mechanism, a rotary motion mechanism, an energy storage release mechanism and an electromagnetic trip mechanism, a motor driving mechanism and a motor position detecting mechanism, an electronic control board, a manual operation mechanism, a safety padlock mechanism, etc., wherein: the contact system is provided with a plurality of groups of moving contacts and fixed contacts, so the contact system is called a multipolar contact, and the switching on and off of the power utilization system is realized by controlling the separation and combination of the moving contacts and the fixed contacts. The rotary action mechanism comprises an energy storage mechanism and a switching mechanism, the energy storage mechanism and the switching mechanism work relatively independently, the switching mechanism is connected with the contact system to switch on and off, and the energy storage mechanism drives the switching mechanism to act through energy storage so as to realize quick switching when needed. The motor driving mechanism drives the energy storage mechanism to store energy on one hand and drives the switching mechanism to switch on the other hand. The electromagnetic tripping mechanism is separated from the energy storage mechanism by controlling the energy storage release mechanism, and the huge restoring force generated by the energy storage mechanism pushes the opening and closing mechanism to act rapidly so as to realize opening and closing.
The motor driving mechanism, the motor position detecting mechanism, the electromagnetic tripping mechanism, the contact position detecting mechanism (specifically, the blade switch and the like) and the like are connected to the electronic control board, so that energy storage, switching-off and switching-on control can be performed through the electronic control board, and the electronic control board can also transmit signals to a remote service end or a client end, so that remote control is convenient.
The rotating action mechanism is provided with the energy storage mechanism and the opening and closing mechanism, wherein the potential energy of the energy storage spring and the potential energy of the opening and closing spring independently act on the moving contact component of the multipolar rotating contact, namely the energy storage spring and the opening and closing spring can not form a remarkable and actual spring series effect in operation, which is beneficial to realizing rapid automatic opening and closing.
The isolating switch can also be manually operated, and the manual operating mechanism and the safety padlock mechanism are arranged for the purpose, so that the opening and closing operations can be carried out through the manual operating mechanism, and the safety padlock mechanism can lock the manual operating mechanism under normal conditions so as to ensure the normal use of the isolating switch. Therefore, the isolating switch has the main functions of remote automatic quick switching-off, remote automatic quick switching-on, detection of the on-off state of the isolating switch, manual switching-on and switching-off padlock and the like.
The isolating switch of the present invention can be operated either manually or automatically, as described in detail below.
1.1 Manual operation
The contact is in an open state, and the manual operating mechanism and the contact position indicator (both can be integrally designed) are in corresponding open indication positions (hereinafter referred to as OFF positions); the product contact is in the ON state, and the manual operating mechanism and the contact position indicator are in the corresponding ON indication position (hereinafter referred to as the ON position). Corresponding to the energy storage, opening and closing states, the following operation mode can be adopted.
(1) Manual switch-on in non-energy-storage state
The disconnector has such a state: the product contact is in an OFF state, the energy storage mechanism in the rotary action mechanism does not store energy, the opening and closing mechanism is in an OFF position, and the manual operation mechanism is in the OFF position. When the manual switching-ON operation is executed, the manual operation mechanism is twisted from an OFF position to an ON position, and a main shaft in the manual operation mechanism drives an energy storage mechanism and a switching mechanism in the rotary operation mechanism to rotate, so that the manual energy storage and the switching-ON action of the moving contact component are respectively completed. The product enters a locking state of manual energy storage and is not later than the completion of the closing action of the moving contact component.
The energy storage spring in the energy storage mechanism has certain initial potential energy when not storing energy; the opening and closing spring in the opening and closing mechanism also has certain reserved potential energy when the contact is at the OFF position. The initial potential energy of the energy storage spring is approximately equivalent to the reserved potential energy of the opening and closing spring at the OFF position.
In the process that the energy storage mechanism is driven by the main shaft to turn from the OFF position to the ON position, potential energy in the energy storage spring is gradually increased. When the energy storage mechanism rotates beyond a certain angle (e.g. 85 deg.), the energy storage mechanism enters a locked state and is in an energy storage position, but in order to ensure reliable locking, the energy storage mechanism also has a super-rotation angle, which is not more than 30 deg..
In the process that the opening and closing mechanism is driven by the main shaft to turn from the OFF position to the ON position, potential energy in the opening and closing spring is suddenly and rapidly released after being gradually increased, so that the high-speed rotation of the moving contact component in the contact stage is realized. When the opening and closing mechanism rotates to a certain angle (such as 80-90 degrees), the opening and closing spring can be suddenly released. In the foregoing process, the on-OFF spring still has a retained potential energy substantially equivalent to that of its OFF position after the potential energy is rapidly released.
(2) Manual switch-on in stored energy state
The disconnector has in addition such a state: the movable contact component is in an open state, the manual operating mechanism is in an OFF position, and the energy storage mechanism is in an energy storage and unreleased state. At this time, when the manual closing operation is performed, the manual operation mechanism is twisted from the OFF position to the ON position, and the mechanism main shaft in the manual operation mechanism drives the opening and closing mechanism in the action mechanism part to rotate, thereby completing the manual closing operation of the movable contact part. The energy storage mechanism is kept at the energy storage position. In the process that the opening and closing mechanism is driven by the main shaft to turn from the OFF position to the ON position, potential energy in the opening and closing spring is suddenly and rapidly released after being gradually increased, so that the high-speed rotation effect of the moving contact component in the contact stage is realized. When the opening and closing mechanism rotates to a certain angle (such as 80-90 degrees), the opening and closing spring can be suddenly released. In the foregoing process, the on-OFF spring still has a retained potential energy substantially equivalent to that of its OFF position after the potential energy is rapidly released.
(3) Manual brake separating device
The disconnector also has such a state: the movable contact part is at the ON position, and the manual operating mechanism is at the ON position. When the manual opening operation is executed, the manual operation mechanism is twisted from the ON position to the OFF position, and a mechanism main shaft in the manual operation mechanism drives the opening and closing mechanism in the action mechanism part to rotate, so that the manual opening operation of the movable contact part is completed. The energy storage mechanism is kept at the energy storage position and is not moved at the moment, so that potential energy in the energy storage spring is ensured not to be released. In the process that the opening and closing mechanism is driven by the main shaft to turn from the ON position to the OFF position, the potential energy in the opening and closing spring is suddenly and rapidly released after being gradually increased, so that the high-speed rotation effect of the moving contact component in the contact stage is realized. When the opening and closing mechanism reversely rotates to a certain angle (such as 80-90 degrees), the opening and closing spring can be suddenly released. In the foregoing process, the split spring still has a retained potential energy after the potential energy is released rapidly.
1.2 automatic operation
(1) Automatic closing in non-energy-storage state
The disconnector has such a state: the product moving contact component is in an OFF state, the manual operating mechanism is in an OFF position, and the energy storage mechanism in the action mechanism component is in an energy storage-free state. After the isolating switch receives the automatic closing instruction at this time, the electronic control board can firstly confirm the motor position signal and the contact position signal, and when the signals are not abnormal, the electronic control board sends out the instruction to drive the closing motor to start closing rotation. The switching-on motor firstly drives an energy storage mechanism in a rotating action mechanism part to rotate through a sector gear in a reduction gear train to perform automatic energy storage action; at this time, the manual operating mechanism still stays at the OFF position, and the opening and closing mechanism in the actuating mechanism component does not act until the energy storage mechanism enters a locking state of automatic energy storage under the action of the closing motor.
In the invention, the locking state of automatic energy storage and the locking state of manual energy storage can be consistent.
In addition, in order to reduce the volume and the load of the motor, after the energy storage mechanism enters an automatic locking state, the switching mechanism starts to rotate from the OFF position to the ON position under the driving of the motor so as to perform automatic switching-ON action, and the switching mechanism can drive the manual operation mechanism to rotate from the OFF position to the ON position together. To ensure the effectiveness of the action, it is also usual to deliberately pull away the energy storage mechanism after it has been fully locked and before the opening and closing mechanism has started to rotate for a period of time expressed by the angle of rotation of the sector gear in the reduction train, which is not greater than 40 °. In the process that the switching mechanism is driven by the motor to turn from the OFF position to the ON position, potential energy in the switching spring is gradually increased and then suddenly and rapidly released, so that the high-speed rotation effect of the moving contact component in the contact stage is realized. When the opening and closing mechanism rotates to a certain angle (such as 80-90 degrees), the opening and closing spring can be suddenly released. In the foregoing process, the on-OFF spring still has a retained potential energy substantially equivalent to that of its OFF position after the potential energy is rapidly released.
(2) And automatically closing in the stored energy state.
The disconnector has such a state: the moving contact component is in an open position, the manual operating mechanism is in an OFF position, but the energy storage mechanism in the operating mechanism component is in an energy storage locking state. When the isolating switch receives an automatic closing instruction, the electronic control board can firstly confirm a motor position signal and a contact position signal, and when the signals are not abnormal, the electronic control board sends out an instruction to drive the closing motor to start closing rotation. Because the energy storage mechanism is in an energy storage locking state, the switching-ON motor directly drives a switching-ON spring mechanism in the action mechanism part to rotate from an OFF position to an ON position through a sector gear in the reduction gear train to perform automatic switching-ON action; and the opening and closing mechanism drives the manual operation mechanism to rotate from the OFF position to the ON position together. In the process that the switching mechanism is driven by the motor to turn from the OFF position to the ON position, potential energy in the switching spring is gradually increased and then suddenly and rapidly released, so that the high-speed rotation effect of the moving contact component in the contact stage is realized. When the opening and closing mechanism rotates to a certain angle (such as 80-90 degrees), the opening and closing spring can be suddenly released. In the foregoing process, the on-OFF spring still has a retained potential energy substantially equivalent to that of its OFF position after the potential energy is rapidly released.
(3) Automatic brake separating device
The isolating switch is in a closing state, namely the moving contact part is in an ON state, and the handle operating part is in an ON position. When the isolating switch receives an automatic brake-separating instruction, the electronic control board firstly confirms a motor position signal and a contact position signal, and when the signals are not abnormal, the electronic control board sends an instruction to actuate an electronic tripping coil (a device which can be specifically designed in a monostable mode or a bistable mode) to act, the electronic tripping coil further triggers an energy storage release mechanism, and the energy storage release mechanism releases the locking state of the energy storage mechanism. When the locking state of the energy storage mechanism is released, the energy storage mechanism starts to reversely rotate at a high speed from the locking position. The energy storage mechanism reversely rotates from the locking position by an angle not exceeding 20 degrees, and drives the switching mechanism and the manual operating mechanism to rotate from the OFF position to the ON position sequentially but almost simultaneously, so that abnormal increase of potential energy of a spring in the switching mechanism is avoided. Particularly, in the automatic opening and closing process, potential energy of the energy storage mechanism is released rapidly, and the moving contact component, the opening and closing mechanism and the manual operation mechanism are rotated rapidly simultaneously by colliding with a part which is in the opening and closing mechanism and is not flexibly connected with the rotating moving contact component, so that the moving contact component is opened rapidly.

The energy storage release mechanism 140 and the electromagnetic tripping mechanism are used for rapidly triggering the energy storage lock assembly 133 of the energy storage mechanism 131 to be separated from the energy storage rocker arm 17, so that automatic rapid brake separation is realized through energy release. The motor driving mechanism can drive the energy storage rocker arm 17 in the energy storage mechanism 133 and the switching rocker arm 22 in the switching mechanism 132 respectively, so as to realize rapid energy storage and switching.
The present invention focuses on the improvement of the rotary actuator 130, as described in detail below.
As shown in fig. 11, the rotation action mechanism 130 includes an energy storage mechanism 131 and a separation and combination mechanism 132, in which: the energy storage mechanism 131 comprises an energy storage rocker arm 17 and an energy storage spring 15, and is simultaneously provided with an energy storage lock assembly 133, an energy storage release mechanism 140 and the like; the opening and closing mechanism 132 includes an opening and closing rocker arm 22, an opening and closing spring 6, and an opening and closing turnbuckle 7, and is provided with a turnbuckle lock assembly 135, a turnbuckle pressing assembly 134, and the like, and the specific structure and assembly are as follows.
In the invention, the energy storage rocker arm 17, the energy storage spring 15, the opening and closing rocker arm 22, the opening and closing spring 6 and the opening and closing turnbuckle 7 are coaxially arranged on the main shaft 19, wherein the energy storage rocker arm 17, the opening and closing rocker arm 22 and the opening and closing turnbuckle 7 can be arranged in a lamination mode. The energy storage spring 15 is a torsion spring, which is supported on the top of the energy storage rocker 17, and two feet can respectively apply force to the energy storage rocker 15 and the mechanism-level housing 120. Here, the energy storage spring support 16 is mounted on the housing 120, and both legs of the energy storage spring 15 are respectively located at both sides of the energy storage spring support 16, so that the energy storage spring 15 has a reserved potential energy in an initial position. The above-mentioned opening and closing spring 6 is a torsion spring, which is supported on the top of the opening and closing turnbuckle 7, and two feet are respectively applied to the opening and closing turnbuckle 7 and the opening and closing rocker arm 22. The energy storage lock assembly 133 is directly or indirectly mounted on the mechanism-level housing 120, and locks or unlocks the energy storage rocker arm 17 in a corresponding energy storage state, and is realized by the energy storage release mechanism 140 when released; the latch assembly 135 and the latch pressing assembly 134 are directly or indirectly mounted to the mechanism-level housing 120 to lock or unlock the split-latch 7 in the corresponding split-latch state, wherein the latch assembly 135 can act on the energy storage rocker 17, the split-latch rocker 22 and the split-latch 7 at the same time, so as to simplify the structure. Thus, after the assembly is completed, the isolating switch can be respectively subjected to energy storage, switching on and switching off by operating the rotary actuating mechanism 130.
The invention optimizes the positioning or limiting modes of the energy storage rocker arm 17, the opening and closing rocker arm 22 and the opening and closing turnbuckle 7, and specifically comprises the following steps: the energy storage rocker arm 17, the split rocker arm 22 and the split turnbuckle 7 can be configured in a stacked manner, wherein the energy storage rocker arm 17 can be rotationally arranged on the main shaft 19 within a certain angle, the split rocker arm is circumferentially fixedly arranged on the main shaft 19, the split turnbuckle 7 can be rotationally arranged on the main shaft 19 within a certain angle, the bottom of the split turnbuckle 7 is limited by the base 122, the split turnbuckle 7 is associated with the energy storage rocker arm 17 and the split rocker arm 22, the energy storage rocker arm 17 and the split rocker arm 22 are not directly connected, and the split turnbuckle 22 can only be touched by the energy storage rocker arm 17 to rotate in the energy storage releasing process.
The energy storage rocker arm 17, the opening and closing rocker arm 22 and the opening and closing turnbuckle 7 are operated in the following modes: when the energy storage, the opening and the closing are manually carried out, the energy storage rocker arm 17 and the opening and closing rocker arm 22 are driven to rotate forwards or reversely by the rotating main shaft 19, and the opening and closing turnbuckle 7 and the opening and closing rocker arm 22 rotate in a following way under the action of the opening and closing spring 6; when the energy is automatically stored, the energy storage rocker arm 17 rotates forward, the separating rocker arm 22 and the separating and combining turnbuckle 7 do not rotate at first, after a period of time, the energy storage rocker arm 17 drives the main shaft 19 to rotate, the main shaft 19 drives the separating and combining rocker arm 22 to rotate, and the separating and combining turnbuckle 7 follows rotation under the cooperation of the separating and combining rocker arm 22 and the separating and combining spring 6; if the switching-on is performed when the energy storage is completed, the energy storage rocker arm 17 is locked and does not rotate, at the moment, the switching-on and switching-off rocker arm 22 is driven to rotate, and when the switching-on and switching-off turnbuckle 7 is released from the jacking, the switching-on and switching-off turnbuckle 7 follows the rotation under the action of the switching-on and switching-off rocker arm 22 and the switching-on and switching-off spring 6; if the brake is opened when the energy storage is completed, the lock on the energy storage rocker arm 17 is released, the energy storage rocker arm 17 reversely rotates under the action of the energy storage spring, and then the brake release and closing turnbuckle 7 is touched to enable the brake release and closing turnbuckle 7 to rapidly rotate reversely, and in the process, the brake release and closing rocker arm 22 can reversely rotate along with the brake release and closing turnbuckle 7 under the action of the brake release and closing spring 6.
The structure has the advantages that: when the energy storage is released, the energy storage rocker arm 17 rotates reversely rapidly after the energy storage spring 15 is released, the striking opening and closing turnbuckle 7 rotates reversely, the opening and closing rocker arm 22 also rotates reversely after a little delay, at this time, the opening and closing spring 6 acting between the opening and closing turnbuckle 7 and the opening and closing rocker arm 22 cannot be further compressed, namely the potential energy of the opening and closing spring 6 cannot be increased, so that the energy storage spring 15 overcomes the reaction force of the opening and closing spring 6 acting on the opening and closing turnbuckle 7 more easily, and drives the opening and closing turnbuckle 7 to open and close the brake position, namely the rapid opening and closing is realized. At this time, because the opening and closing rocker arm 22 and the opening and closing turnbuckle 7 both rotate, the opening and closing spring 6 between them is not propped up and dead, and therefore the opening and closing spring 6 is not further compressed, so that the spring potential energy that the energy storage spring 15 needs to overcome is relatively small, so that the energy storage spring 15 does not need to be made as large as the existing product, thereby being beneficial to realizing the light weight of the product. In order to meet the requirements of the installation mode, the invention specifically designs the energy storage rocker arm 17, the opening and closing rocker arm 22, the opening and closing turnbuckle 7 and related accessories, and the details are as follows.
Referring to fig. 12, and also referring to fig. 10-11, the present invention is configured with an energy storage spring support 16 for supporting the energy storage spring 15, wherein two sides of the energy storage spring support body 161 are respectively provided with folded edges 16a and 16b, and the bottom of the energy storage spring support 16 is bent and formed with two legs 162, so as to be conveniently fixed and inserted into corresponding assembly slots of the base 122. When the energy is not stored, two feet of the energy storage spring 15 are respectively positioned at two sides of the folded edges 16a and 16b of the energy storage spring bracket body 161; after the energy storage starts, one leg 15a of the energy storage spring 15 abuts against the folded edge 16a, and the other leg 15b abuts against a spring pushing surface 174a of an energy storage spring pushing block 174 on the energy storage rocker arm 17, so that the energy storage spring 15 is compressed and stores energy; when the charge rocker arm 17 reaches a predetermined lock position, the charge rocker arm 17 is locked by the charge lock assembly 133. Here, the folded edges 16a and 16b may further be provided with a wire harness port for routing, which will not be described again.

Preferably, the energy storage rocker arm 17 of the present invention is provided with a lining 25, which has a lining body 251, a lining folding block 252a and a lining folding block 252b, wherein the lining body 251 is disposed on the top surface of the energy storage rocker arm 17 to support the energy storage spring 15, the lining folding block 252a is attached to the locking surface 176b of the energy storage locking protrusion 176, and the lining folding block 252b is attached to the spring pushing surface 174a of the energy storage spring pushing block 174 on the energy storage rocker arm 17, so that the strength of the energy storage rocker arm 17 can be increased, and the excessive wear of the energy storage rocker arm is prevented.
(1) Energy storage rocker arm
As shown in fig. 14 to 15, the energy storage rocker arm 17 has a cylindrical energy storage rocker arm body 170 provided with an energy storage rocker arm shaft hole 171, a fan-shaped energy storage operating member slot 172 is provided on the inner wall of the energy storage rocker arm shaft hole 171, the main shaft 19 is mounted in the energy storage rocker arm shaft hole 172, the energy storage operating member 20 is connected to the main shaft 19, and at least part of the energy storage operating member 20 is accommodated in the energy storage operating member slot 172, wherein an angle gap exists between the side wall of the energy storage operating member slot 172 and the energy storage operating member 20. Here, the energy storage operating member 20 may be specifically a connecting pin, which penetrates through a corresponding pin hole of the spindle 19, and an end of the energy storage operating member 20 is accommodated in the energy storage operating member slot 172 to achieve positioning with the spindle 19. Because of the angular play between the side walls of the charge control element slot 172 and the charge control element 20, the charge control arm 17 is mounted semi-freely circumferentially to the main shaft 19, i.e. the charge control arm 17 can rotate within a certain range relative to the main shaft 19. Here, the stored energy operating member slots 172 are single sided or double sided. Preferably, two symmetrical stored energy operator slots 172 are provided to maintain the stored energy operator 20 in force balance.
As shown in fig. 14-15, a fan-shaped turnbuckle tail block groove 177 is formed in the bottom of the energy storage rocker arm 17, and a turnbuckle tail block 73 on the top of the turnbuckle 7 is placed in the turnbuckle tail block groove 173 in a clearance manner, wherein an angle clearance exists between the turnbuckle tail block 73 and the turnbuckle tail block groove 173, so that the energy storage rocker arm 17 is associated with the turnbuckle 7, and the energy storage rocker arm 17 can only touch the turnbuckle 7 in the energy storage releasing process, so that the energy storage rocker arm 17 drives the turnbuckle 7 to rotate within a certain angle range. Here, the tail block groove side 177a is not in contact with the split-and-close turnbuckle tail block 73 in any state, and the tail block groove side 177b can be in contact with the split-and-close turnbuckle tail block 73 only during the energy storage release process. In the process of releasing the energy storage, the energy storage rocker arm 17 reversely rotates, and the side face 177b of the tail block groove props against the side face 73b of the split-close turnbuckle tail block to drive the split-close turnbuckle 7 to reversely rotate. When the energy storage is locked, the energy storage rocker arm 17 is locked and fixed, and the separating and combining turnbuckle 7 can be driven to rotate by the separating and combining rocker arm 22 because of the angular clearance between the separating and combining turnbuckle tail block 73 and the turnbuckle tail block groove 173.

During energy storage, the two feet of the energy storage spring 15 correspondingly exert force on the energy storage spring push block 174 and the energy storage spring support 16. During the energy storage process, the energy storage rocker arm 17 rotates forward, and the spring pushing surface 174a of the energy storage spring pushing block 174 pushes the energy storage rocker arm 17 to rotate forward, namely the spring pushing surface 174a compresses the energy storage spring 15 to store energy; conversely, when the stored energy is released, the stored energy spring 15 drives the stored energy rocker arm 17 to reversely rotate through the spring pushing surface 174 a.
In the present invention, the energy storage rocker arm 17 is locked or unlocked by cooperating with the energy storage shackle 12 of the energy storage lock assembly 133. For this purpose, a rocker arm locking surface 176b is provided on the other side of the energy storage locking projection 176, which can be locked by being hooked by the energy storage lock catch 12 of the energy storage lock assembly. During energy storage, the energy storage rocker arm 17 rotates forward in the range of 80-120 degrees, and the energy storage lock catch 12 hooks the rocker arm locking surface 176b. Upon quick opening, the energy storage latch 12 disengages from the rocker arm latch surface 176b. Since the pressure applied to the rocker arm locking surface 176b during the energy storage locking is greater, the lining 25 can be additionally arranged, and the lining flange 25a and the lining flange 25b can be respectively positioned against the rocker arm locking surface 176b on the energy storage rocker arm 17 and the spring pressing surface 174a of the energy storage spring pushing block 174, so that the abrasion of the energy storage rocker arm 17 is reduced.
In the invention, the energy storage rocker arm is driven by a driving gear 3 in a motor driving mechanism, for this purpose, an energy storage rocker arm sector tooth 175 is arranged on the side surface of the energy storage rocker arm 17, the energy storage rocker arm sector tooth 175 is meshed with an upper layer sector tooth 31 of the driving gear 3 of the motor driving mechanism, and the energy storage rocker arm 17 is driven to compress the energy storage spring 15 to store energy when the driving gear 3 rotates forward. Here, the energy storage rocker arm sector tooth 175 is trapezoidal in shape, its end tooth 175a is thicker than the non-end tooth, but the non-end tooth is uniform in size, and such a tooth structure can withstand larger impacts.
2.1.2 separating and combining mechanism
Referring to fig. 16-21, the opening and closing mechanism mainly comprises an opening and closing rocker arm 22, an opening and closing spring 6, an opening and closing turnbuckle 7 and the like, wherein the opening and closing rocker arm 22 and the opening and closing turnbuckle 7 are sleeved together in a buckled mode, the opening and closing spring 6 is supported on the opening and closing turnbuckle 7, a main body of the opening and closing mechanism is accommodated in a cavity enclosed by the opening and closing rocker arm 22 and the opening and closing turnbuckle 7, and two feet 6a and 6b of the opening and closing spring 6 can respectively exert force on the opening and closing rocker arm 22 and the opening and closing turnbuckle 7.
The opening and closing rocker arm 22 and the opening and closing turnbuckle 7 in the invention have special structures, and are assembled in a snap fit manner, as described below.

At this time, the switching knob 7 and the switching rocker arm 22 can freely rotate within a certain angle, and the following rotation of the switching knob and the switching rocker arm is realized by the switching spring 15.
In the invention, a fan-shaped turnbuckle tail block hole 222 is formed on the separating and combining rocker arm 22, and the turnbuckle tail block hole 222 can pass through the separating and combining turnbuckle tail block 73 with a gap, so that the relevance of the separating and combining rocker arm 22 and the separating and combining turnbuckle 7 is realized. Because of the angle clearance between the separating and closing turnbuckle tail block 73 and the turnbuckle tail block hole 223, the two side surfaces of the fan-shaped turnbuckle tail block hole 222 are not contacted with the separating and closing turnbuckle tail block 73, and the separating and closing rocker arm 22 can be slightly advanced when the separating and closing turnbuckle 7 is reversed.
Here, the turnbuckle tail block hole 222 is opened at a side portion of the opening and closing rocker arm shaft hole 221 on the opening and closing rocker arm body 220, and penetrates through the opening and closing rocker arm shaft hole 221; meanwhile, the opening and closing rocker arm body 220 is provided with an opening and closing operating member slot 226 penetrating the opening and closing rocker arm shaft hole 211 at one side opposite to the turnbuckle tail block hole 222, and is used for accommodating the opening and closing operating member 21. At this time, since the main shaft 19 is not completely enclosed by the opening/closing rocker shaft hole 211, it is required that the engagement position of the opening/closing rocker arm 22 and the disconnecting switch driving gear 3 and the urging position of the opening/closing rocker arm 22 and the opening/closing spring 6 are located on both sides of the opening/closing operation piece groove 222, respectively, so that the resultant force direction of the main shaft 19 is directed to the opening/closing operation piece groove 222 side, whereby the main shaft 19 is held by the opening/closing rocker shaft hole 211 without being separated.
In the present invention, the periphery of the split rocker arm 22 is provided with the split spring push block 224, two feet of the split spring 6 are respectively arranged outside the two side pushing surfaces 224a and 224b of the split spring push block 224, and the split spring 6 is simultaneously clamped at two sides of the split spring stop block 75 on the split turnbuckle 7, so that the split spring 6 can correspondingly act on the corresponding split turnbuckle 7 and the split rocker arm 22, and when the split rocker arm 22 rotates positively, the split turnbuckle 7 is driven to rotate by compressing the split spring 6.
At the beginning, the opening and closing turnbuckle 7 is propped against by the turnbuckle supporting leg 8 in a normal state, and the opening and closing needs to be pushed away during closing, so that the opening and closing rocker arm pushing hand 223 is arranged at the bottom of the opening and closing rocker arm 22. Here, the split rocker arm pushing hands 223 are preferably two and oppositely arranged, and the split spring pushing block 224 is located between the two split rocker arm pushing hands 223, each split rocker arm pushing hand 223 is slightly inclined downwards, and the distance between the tail end of the split rocker arm pushing hand 223 and the central line of the main shaft is greater than the distance between the outer wall of the split turnbuckle body and the central line of the main shaft. When the switching-on and switching-off rocker arm pushing hands 223 are at a certain angle from the positions of the turnbuckle supporting feet 8, when the switching-on and switching-off rocker arm 22 rotates forward for 60-110 degrees, one of the switching-on and switching-off rocker arm pushing hands 223 can push away from the turnbuckle supporting feet 8 on the running line, so that the turnbuckle supporting feet 8 release the jacking pressure of the switching-on and switching-off turnbuckle 7 through the switching-on and switching-off rocker arm pushing hands 223, and the switching-on and switching-off turnbuckle 7 can switch on under the pressure of the switching-on and switching-off spring 6. Similarly, when the switching rocker arm 22 reversely rotates to a preset angle, the other switching rocker arm pushing hand 223 can push away the latch hook 18 of the latch assembly 135, so that the switching latch 7 is released from the closing position, and then closing can be performed.
In the invention, the switching rocker arm 22 is also driven by the driving gear 3 to realize automatic switching.
As shown in fig. 17 to 18, the side surface of the split rocker arm 22 is provided with split rocker arm sector teeth 227, and the rocker arm sector teeth 227 mesh with the lower sector teeth 32 of the drive gear 3.

2.2 drive mechanism
The invention is provided with a motor driving mechanism to drive the energy storage rocker arm 17 and the switching rocker arm 22, thereby realizing automatic energy storage and automatic switching-on. Preferably, the energy storage rocker arms 17 and the switching rocker arms 22 share one driving gear 3, which is described in detail below.
Referring to fig. 28-29, the motor driving mechanism is configured with an electric motor 4, the driving gear 3 receives the power of the motor 4, wherein a shaft hole 34 is arranged on the driving gear 3 body 30 and is installed on an output shaft 44, a turbine 43 on the output shaft 44 is meshed with a turbine rod 42, and the turbine rod 42 is connected with the motor 41, so that the intelligent energy storage rocker arm 17 and the switching rocker arm 22 are driven. Here, the driving gear 3 is provided with a gear boss 33 corresponding to the shaft hole 34, so as to enhance the strength of the driving gear 3, and a process hole 35 may be provided beside the driving gear to reduce the weight or balance the driving gear.
In particular, the drive gear 3 according to the invention is provided with an upper layer of teeth 31 and a lower layer of teeth 32, which are non-overlapping on the pitch circle, wherein the upper layer of teeth 31 can mesh with the storage rocker arm teeth 175 and the lower layer of teeth 32 can mesh with the separating and combining rocker arm teeth 227, wherein the sector angle of the upper layer of teeth 31 is greater than the sector angle of the lower layer of teeth 32. Here, the final teeth 31a in the upper layer of sector teeth 31 are thicker than the non-final teeth, and the non-final teeth are uniform in specification. Similar designs may be used in the lower layer of sector teeth 31.
Here, there are two non-tooth spaces on the horizontal indexing circles between the upper layer sector tooth 31 and the lower layer sector tooth 32, wherein a first non-tooth space is formed between the upper layer sector tooth head section tooth and the lower layer sector tooth head section tooth, and a second non-tooth space is formed between the upper layer sector tooth tail section tooth and the lower layer sector tooth tail section tooth, wherein the first non-tooth space is larger than the second non-tooth space. Meanwhile, the upper layer of sector teeth and the lower layer of sector teeth have no tooth space area in the vertical direction. In this way, it is ensured that the drive gear 3 does not simultaneously mesh with the storage rocker arm 17 and the switching rocker arm 22, thereby ensuring that the drive gear 3 has a small load.
Referring to fig. 30, a motor overload curve is shown, with upper and lower lines representing load ranges. The driving gear 3 is in time-sharing engagement with the energy storage rocker arm 17 and the separating and combining rocker arm 22, the overload is gradually increased when the driving gear is in time-sharing engagement with the energy storage rocker arm 17, the overload is 0 when the driving gear is separated from the energy storage rocker arm 17, and the overload is gradually increased again when the driving gear is in time-sharing engagement with the separating and combining rocker arm 22. It will be readily appreciated that the potential energy of the energy storage spring 15 is greater than the potential energy of the on-off spring 5, and thus the overload of the motor driving the energy storage rocker 17 is correspondingly greater than the overload driving the on-off rocker 22.
In the above embodiment, since the opening and closing turnbuckle 7 has the opening and closing turnbuckle tail block 73 capable of being matched with the energy storage rocker arm 7, the opening and closing turnbuckle tail block can be reversely rotated from the ON position to the OFF position under the pushing of the energy storage rocker arm 17 when the potential energy of the energy storage spring 15 is released rapidly.
In the above embodiment, the energy storage rocker arm 17, which is now being pushed by the manual operating mechanism to turn from the energy storage OFF position to the energy storage ON position, cannot catch up and hit all the time during the forward high-speed rotation of the opening and closing turnbuckle 7 from the OFF position to the ON position, including the opening and closing turnbuckle tail block 73. In addition, during the rapid rotation of the energy storage rocker arm 17 for releasing energy from the spring, the energy storage rocker arm can contact and strike the opening and closing turnbuckle tail block 73 of the opening and closing turnbuckle 7 before the energy storage rocker arm reversely rotates from the release position by a rotation angle of not more than 30 degrees, so that the rapid opening of the moving contact assembly is driven, and the potential energy of the energy storage spring 15 can be prevented from being excessively poured into the opening and closing spring 6. When the rotary action mechanism 130 is in a closing state, the energy storage mechanism 131 is at an energy storage ON position, the opening and closing mechanism 132 is at an ON position, and the manual operation mechanism is at a manual ON position. At this time, the opening and closing turnbuckle tail block 73 of the opening and closing turnbuckle 7 maintains an angle clearance of not more than 30 ° with the energy storage rocker arm 7, and an angle clearance of not more than 25 ° is maintained between the energy storage rocker arm 17 and the main shaft 19.
3 working modes
The isolating switch can perform manual or automatic energy storage, closing and opening operations, and is specifically described below.
3.1 working State
The invention defines the working state positions of the corresponding mechanisms of the isolating switch according to the following mode.
After the energy storage mechanism 131 is installed, a proper reserved potential energy can be preset in the energy storage spring 15, so that the energy storage mechanism 131 can be assuredly stopped at an initial position, and the initial position is defined as an OFF position (hereinafter referred to as an energy storage OFF position) of the energy storage mechanism 131. The position of the energy stocking mechanism 131 after stocking and being locked is defined as an ON position of the energy stocking mechanism 131 (hereinafter referred to as an stocking ON position).
The disengaging mechanism 132 also has two defined rest positions. When the energy stocking mechanism 131 is in the OFF position, the determined rest position corresponding to the opening and closing mechanism 132 is defined as the OFF position of the opening and closing mechanism 132 (hereinafter referred to as opening and closing OFF position); another certain rest position is defined as an ON position of the switching mechanism 132 (hereinafter referred to as switching ON position).
Once the stored energy mechanism 131 is in the stored energy OFF position, the on-OFF mechanism 132 must naturally rest in its OFF position as well as the manual operating mechanism. If the energy storage mechanism 131 is in the energy storage ON position, the opening and closing mechanism can be stopped at the OFF position or at the ON position; the manual operating mechanism may rest in a manual OFF position or in a manual ON position. When the opening and closing mechanism 132 is stopped at the OFF position, the manual operation mechanism is necessarily stopped at the manual OFF position; when the opening and closing mechanism 132 is stopped at the ON position, the manual operation mechanism is necessarily stopped at the manual ON position; in addition, there are no other combinations of natural stops.
The isolating switch has three working states, and is shown in a table 1.
Table 1 isolator switch mechanism status
As can be seen from Table 1, the disconnector of the present invention has only three states, wherein the OFF position and the ON position have no definite time sequence.
State of mechanism 1 2 3
Energy storage mechanism OFF ON ON
Separating and combining mechanism OFF OFF ON
Manual operating mechanism OFF OFF ON
Referring to fig. 31-40, the relative mechanism and component positions, and operational relationships are shown in corresponding states.
As shown in fig. 31, the knob 110 is fixedly mounted on the main shaft 19, and the operation of storing energy, closing and opening can be performed by rotating the knob 110. Knob 110 has two steady state positions indicating the disconnector state, a manual OFF position and a manual ON position, as shown in particular in fig. 30, wherein the angle between the manual OFF position and the manual ON position is 90 °.
As shown in fig. 32-35, the energy storage mechanism 131 has two steady-state positions, namely an energy storage OFF position and an energy storage ON position. When the energy is stored in the OFF position, the manual operation mechanism and the opening and closing mechanism are both in the OFF position; when the energy storage is in the ON position, the manual operation mechanism and the opening and closing mechanism are both in the OFF position or the ON position.
During energy storage, the energy storage rocker arm 17 rotates, and the energy storage spring 15 stores energy. When the energy storage lock is rotated to the energy storage locking position, the energy storage lock catch 12 is locked with the energy storage rocker arm 17, and the trigger button 10 and the energy storage lock catch 12 are also in a hooked state. When the energy storage is released, the trigger button 10 is hooked with the energy storage lock catch 12 in a contact way, so that the energy storage lock catch 12 is unhooked, and the brake can be separated.
As shown in fig. 32 to 35, when the stored energy OFF position is taken as the stored energy reference line (angle is 0), the position angles of the parts are shown in table 2.
Table 2 relative component position and angle of energy storage mechanism
(symbol) Energy storage state Meaning of Angle (°)

It is understood that table 2 is only one preferred parameter combination, and the engineering may be selected additionally, and will not be repeated.
As shown in fig. 36-37, the opening and closing rocker arm 22 and the opening and closing turnbuckle 7 are closed to the closing position after forward corresponding angles, at this time, the closing position of the main shaft 19 is A1, the closing position of the opening and closing rocker arm 19 is B1, the closing position of the turnbuckle latch hook 18 is C1, the closing position of the opening and closing turnbuckle 7 is D1, the closing position of the turnbuckle supporting leg 8 is E1, and after closing, the turnbuckle latch hook 18 hooks the turnbuckle hook groove 77 of the opening and closing turnbuckle 7.
As shown in fig. 38-39, after the opening and closing rocker arm 22 and the opening and closing turnbuckle 7 are opened, the corresponding angles are reversely rotated to open the brake, at this time, the closing position of the main shaft 19 is A2, the closing position of the opening and closing rocker arm 19 is B2, the closing position of the turnbuckle latch hook 18 is C2, the closing position of the opening and closing turnbuckle 7 is D2, the closing position of the turnbuckle supporting leg 8 is E2, and after the brake is opened, the turnbuckle supporting leg 8 supports against the outer wall of the opening and closing turnbuckle 7 to prevent the turnbuckle from rotating.
As shown in fig. 40, the operational state relationship among the disconnecting switch energy storage rocker arm 17, the switching rocker arm 22, and the switching turnbuckle 7 is as follows:
(1) Energy storage
The energy storage rocker arm 17 is indirectly driven to rotate positively through the rotating main shaft 19, or the energy storage spring 15 is compressed to store energy by directly driving the energy storage rocker arm 17 to rotate positively.
In the energy storage process, or after the energy storage is completed, the switching rocker arm 22 rotates forward under the drive of the main shaft 17 to compress the switching spring 6 for energy storage, and the switching turnbuckle 7 is driven to rotate forward through the switching spring 6, so that the switching-on is finally realized.
In this state, there is no direct connection between the opening and closing turnbuckle 7 and the energy storage rocker arm 17, i.e. there is no contact between the energy storage rocker arm 17 and the opening and closing turnbuckle 7, and the opening and closing turnbuckle 7 rotates positively through the cooperation with the opening and closing rocker arm 22 and the opening and closing spring 6.
In this state, the energy storage can be performed manually or automatically, wherein: when the manual energy storage is realized by rotating a knob which is in positioning connection with the main shaft 19; when the energy is automatically stored, the energy storage rocker arm 17 is directly driven by a motor.
(2) Energy release
After the energy storage rocker arm 17 is unlocked, the energy storage spring 15 is released, and the energy storage rocker arm 17 is driven to rotate reversely under the action of the energy storage spring 15.
In the energy release process, the energy storage rocker arm 17 touches the opening and closing turnbuckle 7 when reversing, so that the opening and closing turnbuckle 7 reverses to realize opening and closing, and the opening and closing can be directly realized by driving the opening and closing turnbuckle 7 to reverse. When the opening/closing clasp 7 is reversed, the opening/closing rocker arm 22 is also reversed: on the other hand, when the energy storage rocker arm 17 is reversed, the energy storage rocker arm 17 contacts the opening and closing turnbuckle 7 to be reversed, and then the opening and closing rocker arm 22 is reversed through the opening and closing spring 6; on the other hand, when the energy storage rocker arm 17 is reversed, the main shaft 19 is simultaneously driven to be reversed, and the combined rocker arm 22 is reversed by the main shaft 19. The switching rocker arm 22 is reversed at the same time as the switching turnbuckle 7 is reversed, so that the switching spring 6 between them is not compressed or further compressed.
In this state, the opening and closing twister 7 is directly associated with the energy storage rocker arm 77, i.e., the opening and closing twister 7 is touched when the energy storage rocker arm 17 is reversed, so that the opening and closing twister 7 rotates, i.e., the opening and closing twister 7 is driven by the energy storage rocker arm 17.
In this state, the release of energy can be performed manually or automatically, i.e. by directly unlocking the energy storage rocker 17, wherein the automatic unlocking of the energy storage rocker can be performed by means of an electromagnet actuation.
(3) Closing switch
The closing needs to be performed when the stored energy is completed and the closing is not completed, and the stored energy rocker arm 17 is locked. The energy storage process of the energy storage rocker arm 17 compressing the energy storage spring 15 is as described above.
During closing, the main shaft 19 is rotated to drive the switching rocker arm 22 to rotate positively, or the switching rocker arm 22 is directly driven to rotate positively, so that the switching spring 6 is compressed to store energy, and the switching turnbuckle 7 is rotated positively to realize closing.
In this state, there is no direct connection between the opening and closing turnbuckle 7 and the energy storage rocker arm 17, i.e. there is no contact between the energy storage rocker arm 17 and the opening and closing turnbuckle 7, and the opening and closing turnbuckle 7 rotates positively through the cooperation with the opening and closing rocker arm 22 and the opening and closing spring 6.
In this state, the closing may be performed manually or automatically, wherein: when the manual switch-on is performed, the switch-on is performed by rotating a knob which is in positioning connection with the main shaft 19; when the automatic closing is performed, the switching rocker arm 22 can be driven to rotate forward by a motor.
(4) Separating brake
The closing is performed under the conditions that the energy storage is completed and the closing is completed.
In this case, the switching rocker arm 22 is driven to rotate reversely by rotating the main shaft 19 while maintaining the locked state of the energy storage rocker arm 17, or the switching rocker arm 22 is directly driven to rotate reversely, so that the action of the switching spring 6 on the switching knob 7 is released, and the switching knob 7 is rotated reversely to perform switching. This applies to manual opening.
In another case, the energy storage rocker arm 17 is unlocked, so that the energy storage spring 15 releases energy, and therefore the energy storage rocker arm 17 directly touches the opening and closing turnbuckle 7, so that the opening and closing turnbuckle 7 is reversed to realize opening and closing, and a specific process can participate in the energy release process. This applies to automatic opening.
In the automatic brake-separating state, brake separation is performed by releasing energy storage. The opening and closing turnbuckle 7 is directly associated with the energy storage rocker arm 17, namely, the energy storage rocker arm 17 contacts with the opening and closing turnbuckle 7 when in reverse rotation, so that the opening and closing turnbuckle 7 rotates, namely, the opening and closing turnbuckle 7 is driven by the energy storage rocker arm 17.
In the above process, the driving force transmission relationship among the energy storage rocker arm 17, the opening and closing rocker arm 22 and the opening and closing turnbuckle 7 is as follows: during energy storage, driving force is transmitted from the main shaft 19 to the energy storage rocker arm 17, meanwhile, driving force is transmitted from the main shaft 19 to the switching rocker arm 22, and driving force is transmitted from the switching rocker arm 22 to the switching turnbuckle 7 through the switching spring 6; when the energy is released, the driving force is transmitted from the energy storage rocker arm 17 to the opening and closing turnbuckle 7, and the driving force is transmitted from the main shaft 19 to the opening and closing rocker arm 22.
2. Working process
The operation of the isolating switch of the present invention will be described below.
The present invention can perform a closing operation by a manual operation mechanism or a motor driving mechanism 160 through the rotation operation mechanism 130. The rotary motion mechanism 130 can perform manual brake-off operation through a manual operation mechanism; when the manual opening operation is performed, the energy storage release mechanism 140 is not triggered, and the energy storage mechanism 131 maintains the locked state of the stored energy. The rotation actuating mechanism 130 can terminate the locking state of the energy storage mechanism 131 by the energy storage releasing mechanism 140, and can act on the opening and closing mechanism 132 by releasing energy storage, thereby realizing automatic opening and closing operation. If the energy storage mechanism 131 is at the energy storage OFF position, when the automatic or manual switching-ON operation is performed, the corresponding manual or automatic energy storage is performed ON the energy storage mechanism, so that the energy storage mechanism is turned from the energy storage OFF position to the energy storage ON position.
There are six modes of disconnector operation, namely: (1) manually opening the switch in a switch-on state; (2) automatically opening the switch in a switch-on state; (3) manual closing in the state of stored energy of the opening brake; (4) automatic closing under stored energy after opening the brake; (5) manual closing in the state of opening the brake and not storing energy; and (6) automatically closing the switch without energy storage. Specifically, the results are shown in Table 3.

Mode of operation Manual brake separating device Automatic brake separating device Manual switch-on Automatic closing switch Manual energy storage switch-on Automatic energy-storage switch-on
Referring to fig. 40, a basic method of operation in six different modes is shown, the operation of which is described in further detail below in conjunction with fig. 40.
(1) Manual brake separating device in closing state
In the case that the energy storage release mechanism 140 does not receive the automatic release command, the trigger lock catch 10 in the energy storage release mechanism 140 is hooked with the energy storage rocker 17 in the energy storage mechanism 131, so that the energy storage mechanism 131 is kept at the energy storage ON position.
When the switch is opened, the manual operation mechanism is reversely rotated from the manual ON position to the manual OFF position under manual operation, and the main shaft 19 is rotated from the ON position to the OFF position by the switch operation member 21 and the switch rocker arm 22, while the switch knob 7 is held at the ON position. When the switching rocker arm 22 rotates to about 85 °, the switching turnbuckle 7 is released, and rapidly rotates from the ON position to the OFF position under the action of the switching spring 6.
(2) Automatic brake separating under closing state
The automatic opening can be performed by releasing the potential energy of the energy storage spring 15 if and only if the energy storage mechanism 131 is resting in the energy storage ON position.
When an automatic opening command is received, the trigger button 10 of the energy storage release mechanism 140 deflects from the locking position, releasing its effect on the energy storage lock 12. The energy storage lock catch 12 cannot be kept at the hooking position under the action of the energy storage rocker arm 17, the energy storage lock catch 12 starts to rotate and finally slides out of the hooking position, and the energy storage rocker arm 17 starts to rapidly rotate from the energy storage ON position to the energy storage OFF position under the action of the energy storage spring 15.
After a rotation of not more than 30 °, the energy storage rocker 17 acts on the spindle 19 and the opening and closing clasp 7 of the manual operating mechanism in succession or simultaneously and drives the two to turn to the OFF position together. After the opening and closing turnbuckle 7 reaches the OFF position, the turnbuckle supporting leg 8 enters the supporting position, so that the opening and closing turnbuckle 7 is ensured to stop at the OFF position and not to rotate. The switching rocker arm 22 eventually also rests in the OFF position under the action of the switching spring 6. The charge rocker arm 17 is stopped in the charge OFF position by the charge spring 15, at which time the two ends of the charge spring 17 also rest on the charge spring support 16.
(3) Manual closing in state of stored energy of separating brake
At this time, the energy storage mechanism 131 of the rotation actuating mechanism 130 is at the energy storage ON position, the manual operation mechanism is rotated from the OFF position to the ON position under the manual operation, the opening and closing swivel 7 is operated by the swivel leg 8 and cannot follow the rotation, and the opening and closing spring 6 installed between the opening and closing rocker arm 22 and the opening and closing swivel 7 is thereby stored with energy. After the opening and closing rocker arm 22 rotates forward to an angle within a closed range of 80-90 degrees, the opening and closing rocker arm pushing hand 223 on the opening and closing rocker arm 22 releases the action of the turnbuckle supporting leg 8 on the opening and closing turnbuckle 7, so that the opening and closing turnbuckle 7 can rotate forward rapidly under the potential energy of the opening and closing spring 6, and the high-speed opening and closing of the isolating switch contact is driven. When the opening and closing turnbuckle 7 rotates to the vicinity of 90 degrees in the forward direction, the turnbuckle hook 18 is acted by the base 122 to stop rotating, and at this time, the turnbuckle hook 18 enters a hooking position with the opening and closing turnbuckle 7 under the action of the opening and closing release spring 27, so that the opening and closing turnbuckle 7 is ensured to be stopped at the ON position. At this time, the energy storage mechanism 131 stopped at the energy storage ON position remains unchanged during the process.
(4) Automatic closing under stored energy of separating brake
When the opening and closing mechanism 132 is at the OFF position and the energy storage mechanism 131 is at the ON position, the energy storage rocker arm sector gear 175 is not at the engagement position, the motor driving mechanism starts to rotate from the initial position after receiving the closing instruction, the sector gear engaged with the energy storage rocker arm sector gear 175 idles, the sector gear engaged with the opening and closing rocker arm sector gear 227 drives the opening and closing rocker arm 22 to rotate from the OFF position to the ON position, the opening and closing turnbuckle 7 of the opening and closing mechanism 132 is influenced by the turnbuckle supporting leg 8 and cannot rotate along with the turnbuckle, and the opening and closing spring 6 arranged between the opening and closing rocker arm and the opening and closing turnbuckle 7 is stored with energy. After the opening and closing rocker arm 22 positively rotates to an angle within a closed range of 80-90 degrees under the drive of the driving gear, the opening and closing rocker arm pushing hand 223 on the opening and closing rocker arm 22 releases the action of the rotary buckle supporting leg 8 on the opening and closing rotary buckle 7, so that the opening and closing rotary buckle 7 can rapidly positively rotate under the potential energy of the opening and closing spring 6, and the high-speed opening and closing of the isolating switch contact is driven. At this time, the switching rocker arm 22 continues to rotate forward under the drive of the motor until the switching rocker arm is meshed and separated. When the opening and closing turnbuckle 7 rotates to the vicinity of 90 degrees in the forward direction, the turnbuckle hook 18 is acted by the base 122 to stop rotating, and at this time, the turnbuckle hook 18 enters a hooking position with the opening and closing turnbuckle 7 under the action of the opening and closing release spring 27, so that the opening and closing turnbuckle 7 is ensured to be stopped at the ON position. The ON/off rocker arm 22 also rests in the ON position under the action of the potential energy retained by the ON/off spring 6. At this time, the energy storage mechanism stopped at the energy storage ON position maintains the state unchanged in the process.
(5) Manual closing in non-energy-storage state of separating brake
The rotary motion mechanism 130 is manually closed when the energy storage mechanism 131 is in the energy storage OFF position, and energy storage is required first. As described above, when the energy storage mechanism 131 is in the energy storage OFF position, the opening and closing mechanism 132 is in the OFF position. When the opening and closing mechanism 132 is at the OFF position, the rotary-button leg 8 acts on the opening and closing rotary button 7 in the opening and closing mechanism 132, so that the opening and closing rotary button 7 is ensured to be stopped at the OFF position.
The manual operating mechanism starts from the manual OFF position and rotates forward to the manual ON position, and the manual operating mechanism drives the energy storage rocker arm 17 and the switching rocker arm 22 to rotate forward through the main shaft 19 and the switching operating piece respectively to store energy for the energy storage spring 15 and the switching spring 6. After the manual operating mechanism drives the energy storage rocker arm 17 to rotate forward from the energy storage OFF position by an angle of not less than 85 °, the energy storage mechanism 132 starts to enter the lock-up state, and the lock-up is completed before the aforementioned forward rotation is performed to an angle of not more than 115 °. The energy storage lock catch 12 enters a hooking position between 85 degrees and 115 degrees of rotation under the action of the energy storage lock catch spring 13 and is hooked with the energy storage rocker arm 17 to finish locking of the energy storage mechanism 131.
Then, the manual operating mechanism drives the opening and closing rocker arm to rotate forward from the OFF position, the opening and closing turnbuckle 7 is acted by the turnbuckle supporting leg 8 and cannot rotate along with the turnbuckle supporting leg, and the opening and closing spring 6 arranged between the opening and closing rocker arm 22 and the opening and closing turnbuckle 7 is stored with energy. After the opening and closing rocker arm 22 rotates forward to an angle within a closed range of 80-90 degrees, the opening and closing rocker arm pushing hand 223 on the opening and closing rocker arm 22 releases the action of the turnbuckle supporting leg 8 on the opening and closing turnbuckle 7, so that the opening and closing turnbuckle 7 can rotate forward rapidly under the potential energy of the opening and closing spring 6, and the high-speed opening and closing of the isolating switch contact is driven. When the opening and closing turnbuckle 7 rotates to the vicinity of 90 degrees in the forward direction, the turnbuckle hook 18 is acted by the base 122 to stop rotating, and at this time, the turnbuckle hook 18 enters a hooking position with the opening and closing turnbuckle 7 under the action of the opening and closing release spring 27, so that the opening and closing turnbuckle 7 is ensured to be stopped at the ON position.
(6) Automatic closing in non-energy-storage state of opening
In this case, the rotary motion mechanism 130 requires automatic energy storage before automatic closing in advance when the energy storage mechanism is in the OFF position.
When the motor driving mechanism starts to execute the closing instruction, the driving gear 3 starts to rotate from the initial position, and after the motor driving mechanism rotates by an angle not more than 40 degrees, the motor driving mechanism is meshed with the energy storage rocker fan teeth 175 ON the energy storage rocker 17 in the energy storage mechanism 131 at first, drives the energy storage rocker 175 to start to rotate forward from the energy storage OFF position to the energy storage ON position, and starts to store energy for the energy storage spring 15.
After the drive gear 3 drives the energy storage rocker arm 17 to rotate forward by an angle not less than 85 ° from the energy storage OFF position, the energy storage mechanism 131 starts to enter a locked state; the drive gear 3 and the energy storage rocker arm sector tooth 175 are disengaged before the forward rotation to an angle of not more than 115 degrees, and after the energy storage rocker arm 17 is disengaged, reverse rotation at an angle of not more than 30 degrees occurs under the action of the energy storage spring 15, and then locking is completed. The energy storage lock catch 12 enters a hooking position between 85 degrees and 115 degrees of rotation under the action of the energy storage lock catch spring 13 and is hooked with the energy storage rocker arm 17 to finish locking of the energy storage mechanism.
The sector gear on the switching rocker arm 22 does not mesh with the drive gear 3 until the energy stocking mechanism 131 is disengaged from the drive gear 3. After the energy storage rocker arm 17 is meshed with the driving gear 3 and separated from the driving gear, the driving gear continues to rotate for an angle not more than 30 degrees, then is meshed with the sector gear of the opening and closing rocker arm 22, and then drives the opening and closing rocker arm 22 to rotate from the OFF position to the ON position, the opening and closing turnbuckle 7 of the opening and closing mechanism 22 cannot rotate along with the rotation due to the action of the turnbuckle supporting leg 8, and the opening and closing spring 6 arranged between the opening and closing rocker arm 22 and the opening and closing turnbuckle 7 is stored with energy. After the opening and closing rocker arm 22 positively rotates to an angle within a closed range of 80-90 degrees under the drive of the driving gear 3, the opening and closing rocker arm pushing hand 223 on the opening and closing rocker arm 22 releases the pushing action of the rotary buckle supporting leg 8 on the opening and closing rotary buckle 7, so that the opening and closing rotary buckle 7 can rapidly positively rotate under the potential energy action of the opening and closing spring 6, and the high-speed opening and closing of the isolating switch contact is driven. At this time, the switching rocker arm 22 continues to rotate forward until the switching rocker arm is meshed and separated under the drive of the motor. When the opening and closing turnbuckle 7 rotates to the vicinity of 90 degrees in the forward direction, the rotation is stopped under the action of the base 122, and at this time, the turnbuckle latch hook 18 enters a hooking position with the opening and closing turnbuckle 7 under the action of the latch spring, so that the opening and closing turnbuckle 7 is ensured to be stopped at the ON position. The ON/off rocker arm 22 also rests in the ON position under the action of the potential energy retained by the ON/off spring 6. The energy storage mechanism 131 resting in the energy storage ON position remains unchanged during this process.

1. the rotary actuating mechanism 130 of the isolating switch comprises an energy storage mechanism 131 and a switching mechanism 132, and through configuration of necessary external functional components, such as a manual operating mechanism or an automatic switching mechanism, and the cooperation of components such as an energy storage release mechanism 140, the quick switching on and switching off of a circuit system can be completed, wherein potential energy of the energy storage spring 15 and potential energy of the switching spring 6 respectively act independently, so that a series spring effect is avoided, the energy storage spring can be made small, and the product weight is convenient to realize.
2. The automatic energy storage, automatic closing and automatic opening are realized through the driving gear 3. The energy storage rocker arm 17 of the energy storage mechanism 131 is provided with energy storage rocker arm sector teeth 175 for automatic energy storage, and sector angles continuously existing on a dividing circle are between 80 degrees and 120 degrees; the last tooth of the sector gear when the sector gear is meshed with the drive gear 3 in the forward direction is abnormally thick to bear the impact force when the sector gear is meshed with the drive gear. The opening and closing rocker arm 22 of the opening and closing mechanism 132 is provided with sector teeth for automatic closing, and sector angles continuously existing on a dividing circle are between [65 degrees, 110 degrees ]. The drive gear has upper and lower layers of non-overlapping sector teeth on the pitch circle, one layer of sector teeth being designed to engage the energy storage rocker arm sector teeth and the other layer of sector teeth being designed to engage the split rocker arm, there being two designed toothless regions between successive sectors of the two layers of sector teeth on the pitch circle for ensuring that the drive gear does not engage both the energy storage rocker arm and the split rocker arm at the same time, thereby ensuring that the drive gear has a small load. The sector of the accumulator rocker 17 that engages, the last tooth that engages, is designed to be exceptionally large to withstand the impact forces of disengagement.
3. The manual operating mechanism is provided with an operating knob, a main shaft, a handle fixing pin and other parts, and the manual opening and closing can be realized by rotating the knob.
4. The opening and closing turnbuckle 7 is provided with an opening and closing turnbuckle tail block 73 which can be in inverse rotation from the ON position to the OFF position under the pushing of the energy storage rocker arm 17 when the potential energy of the spring is released rapidly. During the entire forward high-speed rotation of the split and close turnbuckle 7 from the OFF position to the ON position, any feature, including the split and close turnbuckle tail block 73 described above, is always unable to catch and strike the energy storage rocker arm 17. In the action of the automatic release process, the energy storage rocker arm 17 can contact and strike the on-off turnbuckle tail block 73 of the on-off turnbuckle 7 to drive the quick opening of the moving contact before the energy storage rocker arm reversely rotates by not more than 30 degrees from the release position in the quick rotation of the energy storage spring release energy, so that the potential energy of the energy storage spring 15 can be prevented from being excessively poured into the on-off spring 6.
