The utility model discloses a can long-range energy storage and switch-off and switch-on operation's switch belongs to a section deciliter an organic whole, the miniaturized, intelligent isolator that possess quick separating brake ability.

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments, but it should not be understood that the scope of the present invention is limited to the following embodiments.

1 System scheme

Referring to fig. 1, a system structure of the novel isolating switch is shown, which has a plurality of functional mechanisms, specifically including a contact system, a contact position detecting mechanism, a rotary actuating mechanism, an energy storage releasing mechanism, an electromagnetic tripping mechanism, a motor driving mechanism, a motor position detecting mechanism, an electronic control board, a manual operating mechanism, a safety padlock mechanism, etc., wherein: the contact system is provided with a plurality of groups of moving contacts and static contacts, so the contact system is called a multi-pole contact, and the switching-on and switching-off of the power utilization system are realized by controlling the separation and combination of the moving contacts and the static contacts. The rotating action mechanism comprises an energy storage mechanism and a switching-on and switching-off mechanism, the energy storage mechanism and the switching-on and switching-off mechanism work relatively independently, the switching-on and switching-off mechanism is connected with the contact system to perform switching-on and switching-off, and the energy storage mechanism can conveniently drive the switching-on and switching-off mechanism to act to realize rapid switching-off through energy storage. The motor driving mechanism drives the energy storage mechanism to store energy on one hand and drives the opening and closing mechanism to close 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 rapidly act so as to realize opening.

The motor driving mechanism, the motor position detection mechanism, the electromagnetic tripping mechanism, the contact position detection mechanism (specifically, a blade switch and the like) and the motor position detection mechanism (specifically, a blade switch 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 server or a client, so that remote control is performed conveniently.

The rotary 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 act on the moving contact part of the multi-pole rotary contact independently, so that the energy storage spring and the opening and closing spring cannot form an obvious and actual spring series effect in operation, and the quick automatic opening is favorably realized.

This realize neotype isolator also can carry out manually operation, sets up manual operation mechanism and safe padlock mechanism for this reason, and accessible manual operation mechanism carries out separating brake and combined floodgate operation like this, and safe padlock mechanism can lock manual operation mechanism under normal conditions to guarantee isolator normal use. Therefore, the isolating switch has the main functions of remote automatic rapid opening and closing, remote automatic rapid closing, on-off state detection of the isolating switch, manual opening and closing, opening and closing of a padlock and the like.

This realize novel isolator both manually operation, also can automatic operation, specifically as follows.

1.1 Manual operation

When the contact is in an OFF state, the manual operating mechanism and the contact position indicator (which can be integrally designed) are in a corresponding OFF indicating position (hereinafter referred to as an OFF position); the product contact is in a connection state, and the manual operating mechanism and the contact position indicator are in corresponding connection indicating positions (hereinafter referred to as ON positions). The following operation modes can be adopted corresponding to the energy storage, the brake opening state and the closing state.

(1) Manual switch-on under non-energy storage state

The disconnector has a state: when 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 manual closing operation is executed, the manual operating mechanism is twisted from an OFF position to an ON position, and a main shaft in the manual operating mechanism drives an energy storage mechanism and a separating and combining mechanism in the rotating action mechanism to rotate so as to respectively complete manual energy storage and closing actions of the moving contact part. 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 part.

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 has certain reserved potential energy when the contact is at the OFF position. The initial potential energy of the stored energy spring is substantially equivalent to the retained potential energy of the opening and closing spring in 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, the potential energy in the energy storage spring is gradually increased. When the energy storage mechanism rotates beyond a certain angle (such as 85 degrees), the energy storage mechanism enters a locking state and is located at an energy storage position, but in order to ensure reliable locking, the energy storage mechanism also has an over-rotation angle which is not more than 30 degrees.

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 gradually increased and then suddenly and quickly released, and therefore the moving contact part in the contact stage rotates at a high speed. When the opening/closing mechanism rotates within a certain angle (e.g., 80 ° to 90 °), the opening/closing spring is suddenly released. In the foregoing process, the opening and closing spring, after rapidly releasing potential energy, still has a retained potential energy substantially equivalent to that of its OFF position.

(2) Manual switch-on under stored energy state

The isolating switch has another state: the movable contact part is in a disconnected 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 operating mechanism is twisted from the OFF position to the ON position, and the mechanism main shaft in the manual operating mechanism drives the opening and closing mechanism in the moving contact part to rotate, thereby completing the manual closing operation of the moving contact part. And the energy storage mechanism is kept in the energy storage position at the moment. In the process that the switching mechanism is driven by the main shaft to turn from the OFF position to the ON position, potential energy in the switching spring is gradually increased and then suddenly and quickly released, and therefore the effect of high-speed rotation of the movable contact parts in the contact stage is achieved. When the opening/closing mechanism rotates to a certain angle (e.g., 80 ° to 90 °), the opening/closing spring is suddenly released as described above. In the foregoing process, the opening and closing spring, after rapidly releasing potential energy, still has a retained potential energy substantially equivalent to that of its OFF position.

(3) Manual brake separating

The disconnector also has a state: the movable contact part is in the ON position and the manual operating mechanism is in the ON position. When manual brake-separating operation is executed, the manual operating mechanism is twisted from an ON position to an OFF position, a mechanism main shaft in the manual operating mechanism drives a separating and combining mechanism in the action mechanism part to rotate, and the manual brake-separating action of the moving contact part is completed. And the energy storage mechanism is kept at the energy storage position at the moment, so that the potential energy in the energy storage spring is ensured not to be released. In the process that the switching mechanism is driven by the main shaft to turn from the ON position to the OFF position, potential energy in the switching spring is gradually increased and then suddenly and quickly released, so that the effect of high-speed rotation of the movable contact parts in the contact stage is realized. When the switching mechanism rotates reversely to a certain angle (for example, 80 to 90 °), the switching spring is suddenly released. In the foregoing process, the opening and closing spring still has a retained potential energy after the potential energy is rapidly released.

1.2 automatic operation

(1) Automatic switch-on under non-energy storage state

The disconnector has a state: the product moving contact part is in a disconnected state, the manual operating mechanism is in an OFF position, and the energy storage mechanism in the action mechanism part is in an unstowed state. When the isolating switch receives an automatic closing instruction at the moment, the electronic control board can firstly confirm a motor position signal and a contact position signal, and when the signals are abnormal, the electronic control board sends an instruction to prompt the closing motor to start closing and rotating. The closing motor firstly drives an energy storage mechanism in a rotating action mechanism part to rotate through a sector gear in a reduction gear train so as to perform automatic energy storage action; at the moment, the manual operating mechanism still stays at the OFF position, and the switching-on and switching-OFF mechanism in the action mechanism part can not act until the energy storage mechanism enters the locking state of automatic energy storage under the action of the switching-on motor.

This realization is novel, and the locking state of automatic energy storage and the locking state of manual energy storage can be unanimous.

In addition, in order to reduce the volume and the load of the motor, after the energy storage mechanism enters the automatic locking state, the switching mechanism starts to rotate from the OFF position to the ON position under the driving of the motor to perform the automatic switching action, and the switching mechanism drives the manual operation mechanism to rotate from the OFF position to the ON position together. In order to ensure the effectiveness of the action, the energy storage mechanism and the clutch mechanism are usually intentionally pulled apart after being completely locked for a period of time before the rotation of the clutch mechanism, which is expressed by the angle of rotation of the sector gear in the reduction gear train, which is not more 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 quickly released, so that the effect of high-speed rotation of the movable contact parts in the contact stage is realized. When the opening/closing mechanism rotates to a certain angle (e.g., 80 ° to 90 °), the opening/closing spring is suddenly released as described above. In the foregoing process, the opening and closing spring, after rapidly releasing potential energy, still has a retained potential energy substantially equivalent to that of its OFF position.

(2) And automatically switching on the switch under the energy storage state.

The disconnector has a state: the movable contact part is in the OFF position, the manual operating mechanism is in the OFF position, but the energy storage mechanism in the action mechanism part 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 abnormal, the electronic control board sends an instruction to prompt the closing motor to start closing rotation. Because the energy storage mechanism is in an energy storage locking state, the closing motor directly drives a closing 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 so as to perform automatic closing action; and the switching 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 quickly released, so that the effect of high-speed rotation of the movable contact parts in the contact stage is realized. When the opening/closing mechanism rotates to a certain angle (e.g., 80 ° to 90 °), the opening/closing spring is suddenly released as described above. In the foregoing process, the opening and closing spring, after rapidly releasing potential energy, still has a retained potential energy substantially equivalent to that of its OFF position.

(3) Automatic opening brake

The isolating switch is in a closing state, namely the movable contact part is in a connecting state, and the handle operation part is in an ON position. When the isolating switch receives an automatic opening command, the electronic control board firstly confirms a motor position signal and a contact position signal, when the signals are not abnormal, the electronic control board sends a command to actuate an electronic trip coil (specifically, a monostable design or a bistable design device) to act, the electronic trip coil further triggers an energy storage and release mechanism, and the energy storage and 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 rotates reversely within an angle of not more than 20 degrees from the locking position, and the energy storage mechanism can drive the switching mechanism and the manual operation mechanism to rotate from the OFF position to the ON position successively but almost simultaneously so as to avoid the abnormal increase of the potential energy of the spring in the switching mechanism. Particularly, in the automatic brake opening process, the potential energy of the energy storage mechanism is quickly released, and the moving contact part, the opening and closing mechanism and the manual operation mechanism are ensured to rotate quickly at the same time by colliding a part which is in the opening and closing mechanism and is connected with the rotating moving contact part in a non-flexible mode, so that the moving contact part is opened quickly.

Here, the energy storage operation member 20 may be a connection pin, which penetrates through a corresponding pin hole of the main shaft 19, and the end of the energy storage operation member 20 is received in the energy storage operation member groove 172 to realize the positioning with the main shaft 19. Because of the angular clearance between the side wall of the charging operating member groove 172 and the charging operating member 20, the charging rocker arm 17 is semi-freely mounted to the main shaft 19 in the circumferential direction, i.e., the charging rocker arm 17 can rotate relative to the main shaft 19 within a certain range. Here, the charging operator slots 172 are single-sided or double-sided. Preferably, two symmetrical charging operating member slots 172 are provided to maintain the charging operating member 20 in a balanced force.

Here, the locking piece groove side 177a is not in contact with the opening/closing turn-locking piece 73 in any state, and the locking piece groove side 177b can be in contact with the opening/closing turn-locking piece 73 only in the stored energy releasing process. In the energy storage releasing process, the energy storage rocker arm 17 rotates reversely, and the buckling tail block groove side face 177b pushes against the opening and closing rotary buckling tail block side face 73b to drive the opening and closing rotary buckle 7 to rotate reversely. During the energy storage locking, the energy storage rocker arm 17 is fixed by the locking, because there is the angle clearance in deciliter spinner tail block 73 and spinner tail block groove 173 for deciliter spinner 7 can be driven by deciliter rocker arm 22 and rotate.

When energy is stored, the two legs of the energy storage spring 15 correspondingly exert force on the energy storage spring pushing block 174 and the energy storage spring bracket 16. In the energy storage process, the energy storage rocker arm 17 rotates forwards, the spring pushing surface 174a of the energy storage spring pushing block 174 pushes the energy storage rocker arm 17 to rotate forwards, namely the spring pushing surface 174a compresses the energy storage spring 15 for energy storage; 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 novel realization, the energy storage rocker arm 17 is locked or unlocked by matching with the energy storage lock catch 12 of the energy storage lock component 133. Therefore, the other side of the energy storage lock lug 176 is provided with a rocker arm locking surface 176b which can be hooked and locked by the energy storage lock catch 12 of the energy storage lock component. During energy storage, when the energy storage rocker arm 17 rotates forwards within the range of 80-120 degrees, the energy storage lock catch 12 hooks the rocker arm locking surface 176 b. During rapid opening, the energy storage latch 12 disengages from the rocker arm locking surface 176 b. Because the pressure born by the rocker locking surface 176b is larger during energy storage locking, the lining 25 can be additionally arranged, and the lining flange 25a and the lining flange 25b can be closely attached to the rocker locking surface 176b on the energy storage rocker 17 and the spring pushing surface 174a of the energy storage spring pushing block 174 for positioning, so that the abrasion of the energy storage rocker 17 is reduced.

2.2 drive mechanism

This novel configuration motor drive mechanism of realization drives energy storage rocking arm 17 and deciliter rocking arm 22, can realize automatic energy storage and automatic combined floodgate from this. 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 provided with an electric motor 4, the driving gear 3 receives power of the motor 4, wherein the shaft hole 34 is formed in the body 30 of the driving gear 3 and is mounted on the output shaft 44, the worm wheel 43 on the output shaft 44 is meshed with the worm 42, and the worm 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 at a position corresponding to the shaft hole 34 to enhance the strength of the driving gear 3, and a fabrication hole 35 may be provided beside the driving gear to reduce weight or balance.

In particular, the novel middle driving gear 3 is provided with an upper sector gear 31 and a lower sector gear 32, which have no overlapping on the reference circle, wherein the upper sector gear 31 can be meshed with the energy storage rocker arm sector gear 175, the lower sector gear 32 can be meshed with the deciliter rocker arm sector gear 227, and the sector angle of the upper sector gear 31 is larger than that of the lower sector gear 32. Here, the last tooth 31a of the upper segment teeth 31 is thicker than the non-last tooth, and the non-last tooth has a uniform specification. A similar design can be used in the lower scallops 31.

Here, there are two non-tooth spacing areas on the horizontal direction reference circle between the upper layer sector teeth 31 and the lower layer sector teeth 32, where a first non-tooth spacing area is between the first section teeth of the upper layer sector teeth and the first section teeth of the lower layer sector teeth, and a second non-tooth spacing area is between the last section teeth of the upper layer sector teeth and the last section teeth of the lower layer sector teeth, where the first non-tooth spacing area is greater than the second non-tooth spacing area. Meanwhile, the upper layer of fan teeth and the lower layer of fan teeth have non-tooth interval areas in the vertical direction. In this way, it is ensured that the drive gear 3 does not engage with both the accumulator rocker arm 17 and the clutch 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 the load range represented by the upper and lower lines. The driving gear 3 engages the energy storage rocker arm 17 and the switching rocker arm 22 in a time-sharing manner, the overload is gradually increased when the driving gear is engaged with the energy storage rocker arm 17, the overload is 0 when the driving gear is disengaged from the energy storage rocker arm 17, and the overload is gradually increased again when the driving gear is engaged with the switching rocker arm 22.

In addition, the energy storage rocker arm 17 can contact and hit the switching rotary buckle tail block 73 of the switching rotary buckle 7 before reversely rotating by a rotation angle not more than 30 degrees from the releasing position in the quick rotation of the spring releasing energy, so that the movable contact component is driven to be quickly opened, and the potential energy of the energy storage spring 15 can be prevented from being excessively injected into the switching spring 6. In the closed state of the rotary actuator 130, the energy accumulating mechanism 131 is in the energy accumulating ON position, the opening/closing mechanism 132 is in the ON position, and the manual operation mechanism is in the manual ON position. At this time, the opening and closing rotary buckle tail block 73 of the opening and closing rotary buckle 7 keeps an angular gap not larger than 30 degrees with the energy storage rocker arm 17, and an angular gap not larger than 25 degrees is kept between the energy storage rocker arm 17 and the spindle 19.

3 mode of operation

The isolating switch can perform manual or automatic energy storage, closing and opening operations, and is described in detail below.

3.1 operating conditions

The novel operating condition position of the corresponding mechanism of the isolating switch is defined according to the following mode.

After the charging mechanism 131 is installed, the charging spring 15 can be preset with a proper remaining potential energy, so that the charging mechanism 131 can be surely parked at an initial position, which is defined as an OFF position (hereinafter referred to as a charging OFF position) of the charging mechanism 131. The position of the energy stocking mechanism 131 after stocking and being locked is defined as an ON position (hereinafter, referred to as a stocking ON position) of the energy stocking mechanism 131.

The clutch 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 switching mechanism 132 is defined as the OFF position of the switching mechanism 132 (hereinafter referred to as switching OFF/OFF position); the other determined rest position is defined as an ON position of the switching mechanism 132 (hereinafter referred to as switching ON position).

Once the charging mechanism 131 is in the charging OFF position, the clutch mechanism 132 naturally stops in its OFF position, and the manual operating mechanism naturally stops in its manual OFF position. If the energy storage mechanism 131 is in the energy storage ON position, the ON-OFF mechanism can be stopped at the OFF position and also can be stopped at the ON position; the manual operating mechanism may rest in a manual OFF position and may also rest in a manual ON position. When the opening/closing mechanism 132 is stopped at the OFF position, the manual operation mechanism is also necessarily stopped at the manual OFF position; when the opening/closing mechanism 132 is stopped at the ON position, the manual operation mechanism is also necessarily stopped at the manual ON position; there are no other natural docking combinations.

This realize novel isolator totally three kinds of operating condition, specifically as shown in Table 1.

Table 1 states of the disconnecting switch mechanism as can be seen from table 1, the novel disconnecting switch is only in three states, wherein the OFF positions and the ON positions have no definite sequence relation in time sequence.

State of the 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 positions and the action relationships of the relevant mechanisms and parts in the corresponding states are shown.

As shown in fig. 31, the knob 110 is fixed to the main shaft 19, and energy storage, closing, and opening operations can be performed by rotating the knob 110. The knob 110 has two steady state positions indicating the disconnector status, 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 charging mechanism 131 has two steady-state positions, a charging OFF position and a charging ON position. When the energy storage is in the OFF position, the manual operating mechanism and the opening and closing mechanism are in the OFF positions; when the energy storage ON position is adopted, the manual operating mechanism and the opening and closing mechanism are both in an OFF position or an ON position.

When energy is stored, the energy storage rocker arm 17 rotates, and the energy storage spring 15 stores energy. When the energy storage locking position is reached, the energy storage lock catch 12 is hooked and locked with the energy storage rocker arm 17, and the trigger buckle 10 and the energy storage lock catch 12 are also in a hooked state. When the stored energy is released, the trigger buckle 10 is in contact with the energy storage buckle 12 to be hooked, so that the energy storage buckle 12 is also unhooked, and the brake can be switched off.

As shown in fig. 32 to 35, when the energy storage OFF position is taken as the energy storage reference line (angle is 0), the partial component position angles are shown in table 2.

a8	ON	Angle between lug tail end of energy storage lock and energy storage datum line	148.3

It should be understood that table 2 is only one preferred parameter combination, and further selections may be made in the engineering, which is not described again.

As shown in fig. 36 to 37, after the opening/closing rocker arm 22 and the opening/closing turnbuckle 7 are moved forward by a corresponding angle to a closing position, closing is performed at the closing position where the main shaft 19 is at a position a1, the opening/closing rocker arm 19 is at a position B1, the opening/closing position of the turnbuckle latch hook 18 is at C1, the opening/closing position of the opening/closing turnbuckle 7 is at D1, the opening/closing position of the turnbuckle stay 8 is at E1, and after closing, the turnbuckle latch hook 18 hooks the turnbuckle hook groove 77 of the opening/closing turnbuckle 7.

As shown in fig. 38-39, after opening and closing, the switching rocker arm 22 and the switching turnbuckle 7 are reversely rotated by a corresponding angle to perform opening and closing, at this time, the switching-on position of the main shaft 19 is a2, the switching-on position of the switching rocker arm 19 is B2, the switching-on position of the turnbuckle latch hook 18 is C2, the switching-on position of the switching turnbuckle 7 is D2, the switching-on position of the turnbuckle support leg 8 is E2, and after opening and closing, the turnbuckle support leg 8 supports against the outer wall of the switching turnbuckle 7 to prevent the outer wall 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 rotary latch 7 is as follows:

(1) energy storage

The energy storage rocker arm 17 is indirectly driven to rotate forwards by rotating the main shaft 19, or the energy storage rocker arm 17 is directly driven to rotate forwards to compress the energy storage spring 15 for storing energy.

In the energy storage process or after the energy storage is finished, the opening and closing rocker arm 22 rotates forwards under the driving of the main shaft 17 to compress the opening and closing spring 6 for energy storage, the opening and closing rotary buckle 7 is driven to rotate forwards through the opening and closing spring 6, and finally the closing is realized.

In this state, there is no direct association between the engaging and disengaging rotary latch 7 and the energy storage rocker arm 17, that is, there is no contact between the energy storage rocker arm 17 and the engaging and disengaging rotary latch 7, and the normal rotation of the engaging and disengaging rotary latch 7 is realized by the cooperation with the engaging and disengaging rocker arm 22 and the engaging and disengaging spring 6.

In this state, the energy storage can be performed manually or automatically, wherein: during manual energy storage, the manual energy storage is realized by rotating a knob which is connected with the main shaft 19 in a positioning way; when the energy is automatically stored, the energy storage rocker arm 17 is directly driven by the 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 releasing process, the energy storage rocker arm 17 touches the opening and closing rotary buckle 7 when rotating reversely, so that the opening and closing rotary buckle 7 rotates reversely to realize opening, and the opening and closing can be realized by driving the opening and closing rotary buckle 7 to rotate reversely directly. When the opening/closing turn buckle 7 rotates reversely, the opening/closing rocker arm 22 also rotates reversely: on one hand, when the energy storage rocker arm 17 rotates reversely, the energy storage rocker arm touches the opening and closing rotary buckle 7 to rotate reversely, and then the opening and closing rocker arm 22 rotates reversely through the opening and closing spring 6; on the other hand, when the energy storage rocker arm 17 rotates reversely, the main shaft 19 is driven to rotate reversely, and the switching rocker arm 22 is rotated reversely by the main shaft 19. Since the switching rocker arm 22 is also rotated reversely at the same time as the switching turn buckle 7 is rotated reversely, the switching spring 6 between them is not compressed or further compressed.

In this state, the engaging and disengaging rotary fastener 7 is directly associated with the energy storage rocker arm 177, that is, the energy storage rocker arm 17 touches the engaging and disengaging rotary fastener 7 during reverse rotation, so that the engaging and disengaging rotary fastener 7 rotates, that is, the engaging and disengaging rotary fastener 7 is driven by the energy storage rocker arm 17 to realize.

In this state, the energy release can be effected manually or automatically, i.e. by directly unlocking the energy storage rocker arm 17, wherein the automatic unlocking of the energy storage rocker arm can take place by means of an electromagnet actuation.

(3) Closing switch

The closing needs to be performed under the conditions that the energy storage is completed and the closing is not completed, and the energy storage rocker arm 17 is locked at the moment. The energy storage process of the energy storage rocker arm 17 compressing the energy storage spring 15 is as described above.

When the switch is switched on, the main shaft 19 is rotated to drive the switching rocker arm 22 to rotate forwards or directly drive the switching rocker arm 22 to rotate forwards, so that the switching rotary buckle 7 rotates forwards to realize the switch through compressing the energy storage of the switching spring 6.

In this state, the closing can be performed manually or automatically, wherein: when the switch is manually switched on, the switch is realized by rotating a knob which is connected with the main shaft 19 in a positioning way; when the automatic switch-on is performed, the motor may drive the switching rocker arm 22 to rotate forward.

(4) Separating brake

And the closing is performed under the conditions that the energy storage is finished and the closing is finished.

In one case, the switching rocker arm 22 is driven to rotate reversely by rotating the main shaft 19 or the switching rocker arm 22 is directly driven to rotate reversely while the locked state of the energy storage rocker arm 17 is maintained, and the action of the switching spring 6 on the switching turnbuckle 7 is released, so that the switching turnbuckle 7 is rotated reversely to perform opening. 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, the energy storage rocker arm 17 directly touches the on-off rotary buckle 7, and the on-off rotary buckle 7 rotates reversely to realize opening, and the specific process can participate in the energy release process. This applies to automatic opening.

Under the automatic brake-opening state, the brake-opening is carried out through energy storage and release. The on-off rotary buckle 7 is directly related to the energy storage rocker arm 17, namely the energy storage rocker arm 17 touches the on-off rotary buckle 7 during reverse rotation, so that the on-off rotary buckle 7 rotates, namely the on-off rotary buckle 7 is driven by the energy storage rocker arm 17 to realize.

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 turn buckle 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 opening and closing rocker arm 22, and driving force is transmitted from the opening and closing rocker arm 22 to the opening and closing turnbuckle 7 through the opening and closing spring 6; when the energy is released, the driving force is transmitted from the energy storage rocker arm 17 to the engaging and disengaging turn buckle 7, and the driving force is transmitted from the main shaft 19 to the engaging and disengaging rocker arm 22.

2. Working process

The working process of the novel isolating switch is explained below.

The novel closing operation can be carried out through the manual operation mechanism or the motor driving mechanism 160 through the rotating action mechanism 130. The rotary actuating mechanism 130 can perform manual brake opening operation through a manual operating mechanism; during the manual opening operation, the stored energy releasing mechanism 140 is not triggered, and the stored energy mechanism 131 maintains the locked state of stored energy. The rotational operation mechanism 130 can terminate the lock state of the energy accumulating mechanism 131 by the energy accumulating and releasing mechanism 140, and can perform the automatic opening operation by releasing the accumulated energy to act on the opening/closing mechanism 132. If the energy storage mechanism 131 is in the energy storage OFF position, when the automatic or manual closing operation is performed, the energy storage mechanism is manually or automatically stored energy correspondingly, 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 brake under the closing state; (2) automatically opening the brake under the closing state; (3) manually switching on the switch under the state that the switch is switched off and stored with energy; (4) automatically switching on the switch under the condition of stored energy after switching off; (5) manually switching on the switch under the state that the switch is not stored with energy; (6) and the automatic switch-on is carried out under the condition that the switch-off is not stored with energy. Specifically, the results are shown in Table 3.

Referring to fig. 40, the basic operation method in six different modes is shown, and the operation process thereof will be further described in detail with reference to fig. 40.

(1) Manual brake-separating under closing state

Under the condition that the energy storage release mechanism 140 does not receive the automatic release command, the trigger latch 10 in the energy storage release mechanism 140 is hooked with the energy storage rocker arm 17 in the energy storage mechanism 131, so that the energy storage mechanism 131 is kept at the energy storage ON position.

During opening, the manual operation mechanism is manually operated to rotate in the reverse direction from the manual ON position to the manual OFF position, the main shaft 19 is rotated from the ON position to the OFF position by the opening/closing operation member 21 and the opening/closing rocker arm 22, and the opening/closing turn buckle 7 is held at the ON position. When the switching rocker arm 22 rotates to about 85 °, the switching knob 7 is released and rapidly rotates from the ON position to the OFF position by the switching spring 6.

(2) Automatic opening brake under closing state

If and only if the energy stocking mechanism 131 stops at the energy stocking ON position, the automatic opening can be performed by releasing the potential energy of the energy stocking spring 15.

When receiving the automatic opening command, the trigger buckle 10 of the energy storage and release mechanism 140 deflects from the locking position, and releases the action on the energy storage buckle 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-accumulating rocker arm 17 acts successively or simultaneously on the spindle 19 and the engaging and disengaging knob 7 of the manual operating mechanism and drives them to turn to the OFF position together. After the opening and closing turnbuckle 7 reaches the OFF position, the turnbuckle supporting foot 8 enters the supporting position, and the opening and closing turnbuckle 7 is ensured to stop at the OFF position and not to rotate. The switching rocker arm 22 also finally stops at the OFF position under the action of the switching spring 6. The energy storage rocker arm 17 stops at an energy storage OFF position under the action of the energy storage spring 15, and the two ends of the energy storage spring 17 also stop at the energy storage spring bracket 16.

(3) Manual switch-on under the state of energy storage of switch-off

At this time, the energy storage mechanism 131 of the rotational operation mechanism 130 is in the energy storage ON position, the manual operation mechanism is rotated from the OFF position to the ON position by manual operation, the opening/closing turn buckle 7 is not rotated by the action of the turn buckle stay 8, and the opening/closing spring 6 installed between the opening/closing rocker arm 22 and the opening/closing turn buckle 7 is thereby stored with energy. After the opening and closing rocker arm 22 rotates forwards to an angle within a closed interval of 80-90 degrees, the opening and closing rocker arm push hand 223 on the opening and closing rocker arm 22 releases the action of the turn buckle supporting foot 8 on the opening and closing turn buckle 7, so that the opening and closing turn buckle 7 can rotate forwards quickly under the action of 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 rotary buckle 7 rotates to near 90 degrees in the forward direction, the rotation is stopped under the action of the base 122, and at the moment, the rotary buckle latch hook 18 enters the hooking position with the opening and closing rotary buckle 7 under the action of the opening and closing release spring 27, so that the opening and closing rotary buckle 7 is ensured to stop at the ON position. At this time, the charging mechanism 131 parked at the charging ON position maintains the state during this process.

(4) Automatic switch-on under the condition of switch-off stored energy

When the switching mechanism 132 is in the OFF position and the energy storage mechanism 131 is in the ON position, the energy storage rocker arm sector gear 175 is not in the meshing position, after the motor driving mechanism receives a switching instruction, the driving gear 3 starts to rotate from the initial position, after the sector gear meshed with the energy storage rocker arm sector gear 175 idles, the sector gear meshed with the switching rocker arm sector gear 227 drives the switching rocker arm 22 to rotate from the OFF position to the ON position, the switching rotary buckle 7 of the switching mechanism 132 cannot rotate along with the action of the rotary buckle supporting foot 8, and the switching spring 6 arranged between the switching rocker arm and the switching rotary buckle 7 is stored with energy. After the opening and closing rocker arm 22 rotates forward to an angle within a closed interval of 80-90 degrees under the driving of the driving gear, the opening and closing rocker arm push hand 223 on the opening and closing rocker arm 22 releases the action of the turn buckle supporting foot 8 on the opening and closing turn buckle 7, so that the opening and closing turn buckle 7 can rotate forward rapidly 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 to be engaged and disengaged under the driving of the motor. When the opening and closing rotary buckle 7 rotates to near 90 degrees in the forward direction, the rotation is stopped under the action of the base 122, and at the moment, the rotary buckle latch hook 18 enters the hooking position with the opening and closing rotary buckle 7 under the action of the opening and closing release spring 27, so that the opening and closing rotary buckle 7 is ensured to stop at the ON position. The switching rocker arm 22 also stops at the ON position under the action of the potential energy retained by the switching spring 6. At this time, the charging mechanism parked at the charging ON position maintains the state during this process.

(5) Manual switch-on under the state of non-energy-storage of switch-off

When the charging mechanism 131 of the rotary operating mechanism 130 is in the charging OFF position, the charging is required to be performed manually. As described above, when the charging mechanism 131 is in the charging OFF position, the switching mechanism 132 is in the OFF position. When the opening/closing mechanism 132 is in the OFF position, the engaging/closing turn button 7 in the opening/closing mechanism 132 is acted on by the turn button stay 8 to ensure that the engaging/closing turn button 7 is stopped at the OFF position.

Initially, the manual operating mechanism starts from the manual OFF position and rotates to the forward manual ON position, and the manual operating mechanism simultaneously drives the energy storage rocker arm 17 and the switching rocker arm 22 to rotate in the forward direction through the main shaft 19 and the switching operating element respectively, so as to store energy for the energy storage spring 15 and the switching spring 6. After the manual operating mechanism rotates the charging rocker arm 17 forward from the charging OFF position by an angle not less than 85 °, the charging mechanism 132 starts to enter the locked state and completes the locking before the forward rotation by an angle not more than 115 °. The energy storage lock catch 12 enters a hooking position under the action of the energy storage lock catch spring 13 between 85 degrees and 115 degrees of rotation, and is hooked with the energy storage rocker arm 17 to complete the locking of the energy storage mechanism 131.

Then, the manual operation mechanism drives the opening/closing rocker arm to rotate in the forward direction from the OFF position, the opening/closing turn buckle 7 is not rotated following the rotation by the action of the turn buckle arm 8, and the opening/closing spring 6 installed between the opening/closing rocker arm 22 and the opening/closing turn buckle 7 is thereby stored with energy. After the opening and closing rocker arm 22 rotates forwards to an angle within a closed interval of 80-90 degrees, the opening and closing rocker arm push hand 223 on the opening and closing rocker arm 22 releases the action of the turn buckle supporting foot 8 on the opening and closing turn buckle 7, so that the opening and closing turn buckle 7 can rotate forwards quickly under the action of 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 rotary buckle 7 rotates to near 90 degrees in the forward direction, the rotation is stopped under the action of the base 122, and at the moment, the rotary buckle latch hook 18 enters the hooking position with the opening and closing rotary buckle 7 under the action of the opening and closing release spring 27, so that the opening and closing rotary buckle 7 is ensured to stop at the ON position.

(6) Automatic switch-on under the state of non-energy-storage of switch-off

In this case, the rotating mechanism 130 needs to be automatically charged before the automatic closing when the charging mechanism is in the OFF position.

When the motor driving mechanism starts to execute a closing instruction, the driving gear 3 starts to rotate from its initial position, and after rotating by an angle not greater than 40 °, the driving gear first meshes with the energy storage rocker sector teeth 175 ON the energy storage rocker 17 in the energy storage mechanism 131 to drive the energy storage rocker 175 to start to rotate forward from the energy storage OFF position to the energy storage ON position, and start to store energy for the energy storage spring 15.

When the driving gear 3 drives the energy storage rocker arm 17 to rotate forward by an angle not less than 85 degrees from the energy storage OFF position, the energy storage mechanism 131 starts to enter a locking state; the driving gear 3 and the energy storage rocker arm sector gear 175 are disengaged before the forward rotation is carried out to an angle not larger than 115 degrees, the energy storage rocker arm 17 is disengaged and then carries out reverse rotation to an angle not larger than 30 degrees under the action of the energy storage spring 15, and then the locking is finished. The energy storage lock catch 12 enters a hooking position under the action of the energy storage lock catch spring 13 between 85 degrees and 115 degrees of rotation, and is hooked with the energy storage rocker arm 17 to complete the locking of the energy storage mechanism.

The sector teeth on the switching rocker arm 22 do not mesh with the drive gear 3 until the energy storage mechanism 131 disengages from the drive gear 3. After the energy storage rocker arm 17 is disengaged from the drive gear 3, the drive gear continues to rotate by an angle not larger than 30 degrees and then engages with the sector teeth of the switching rocker arm 22, the switching rocker arm 22 is driven to rotate from the OFF position to the ON position, the switching turnbuckle 7 of the switching mechanism 22 cannot rotate along with the action of the turnbuckle supporting foot 8, and the switching spring 6 arranged between the switching rocker arm 22 and the switching turnbuckle 7 is stored with energy. When the opening and closing rocker arm 22 rotates forward to an angle within a closed interval of 80-90 degrees under the driving of the driving gear 3, the opening and closing rocker arm push hand 223 on the opening and closing rocker arm 22 releases the jacking action of the turn buckle supporting foot 8 on the opening and closing turn buckle 7, so that the opening and closing turn buckle 7 can rotate forward rapidly 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 under the driving of the motor until the switching rocker arm is meshed and separated. When the opening and closing rotary buckle 7 rotates to 90 degrees in the forward direction, the rotation is stopped under the action of the base 122, and at the moment, the rotary buckle latch hook 18 enters the hooking position with the opening and closing rotary buckle 7 under the action of the buckle spring to ensure that the opening and closing rotary buckle 7 stops at the ON position. The switching rocker arm 22 also stops at the ON position under the action of the potential energy retained by the switching spring 6. The charging mechanism 131 parked at the charging ON position remains unchanged during this process.

2. 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 an energy storage rocker arm sector gear 175 for automatic energy storage, and the sector angle continuously existing on the reference circle is between [80 degrees ] and [ 120 degrees ]; the last tooth of the sector gear in forward engagement with the driving gear 3 is oversized to withstand the impact force of disengagement. The switching rocker arm 22 of the switching mechanism 132 has sector teeth for automatic switching, and the sector angle continuously existing on the pitch circle is between [65 °, 110 ° ]. The driving gear is provided with upper and lower layers of sector teeth which are not overlapped on a dividing circle, wherein one layer of sector teeth is designed to be meshed with the sector teeth of the energy storage rocker arm, the other layer of sector teeth is designed to be meshed with the dividing and combining rocker arm, and two designed tooth-free areas exist between sectors which are continuously distributed on the dividing circle for ensuring that the driving gear cannot be meshed with the energy storage rocker arm and the dividing and combining rocker arm at the same time, so that the driving gear is ensured to have a small load. And, the sector that the energy storage rocker arm 17 engages, the last tooth that engages, is designed to be exceptionally large to withstand the impact force 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 brake opening and closing can be realized by rotating the knob.

4. The ON-OFF turn buckle 7 is provided with an ON-OFF turn buckle tail block 73 capable of being connected with the energy storage rocker arm 17, and can rotate reversely from the ON position to the OFF position under the pushing of the energy storage rocker arm 17 when the potential energy of the storage spring is released rapidly. During the entire forward high-speed rotation of the engaging and disengaging turnbuckle 7 from the OFF position to the ON position, any feature including the engaging and disengaging turnbuckle tail block 73 cannot catch up 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 hit the separating and combining rotary buckle tail block 73 of the separating and combining rotary buckle 7 to drive the moving contact to be quickly opened before the spring releases energy and rotates reversely by a rotation angle not more than 30 degrees from the release position, so that the potential energy of the energy storage spring 15 can be prevented from being excessively injected into the separating and combining spring 6.
