The electric switch 100 refers to a switching device capable of turning on, carrying, and off a current under normal circuit conditions and turning on, carrying, and off a current under abnormal circuit conditions for a prescribed time. Rotary disconnectors are exemplified by conventional rotary disconnectors. The rotary isolating switch generally comprises an operating system, a contact system, an arc extinguishing system and the like, wherein the on-off of the rotary isolating switch is realized by the contact or separation of a moving contact 30 and a fixed contact 40 in the contact system, the arc extinguishing system is used for extinguishing an arc generated by the breaking of the moving contact 30 and the fixed contact 40, and the operating system is used for controlling the contact system to be closed or opened.
The current rotary isolating switch is easy to generate the phenomenon that a circuit cannot be disconnected in time or the circuit can be disconnected after repeated operation after running for a period of time.
In view of this, the present application provides an operating device for an electric switch. As shown in fig. 1 and 2, the operating device for an electric switch includes a magnetic control assembly 10 and an operating mechanism 20. The magnetic control assembly 10 comprises a magnetic rotator 11 and a magnetic control driving mechanism 12 for driving the magnetic rotator 11 to rotate. The operating mechanism 20 includes a base 21 and a rotating body 22, the base 21 is provided with a rotating hole 211, a first end of the rotating body 22 is connected with the magnetic rotating body 11, and a second end of the rotating body 22 is rotatably connected with the base 21 through the rotating hole 211. The rotating body 22 is used for coupling with the moving contact 30 of the electrical switch 100, and the rotating body 22 can rotate along with the rotation of the magnetic rotating body 11 to drive the moving contact 30 of the electrical switch 100 to move.
The operation device will be described below in connection with the use process of the operation device.
Taking a rotary isolating switch as the electrical switch 100 as an example, referring to fig. 1 and 2, the magnetic control driving mechanism 12 can drive the magnetic rotator 11 to rotate clockwise or counterclockwise. The first end of the rotator 22 is connected to the magnetic rotator 11, and the other end extends into the rotation hole 211 of the base 21 and is rotatably connected to the base 21. The rotor 22 is used for coupling with the moving contact 30 of the rotary isolating switch, and the connection relationship between the two may be that the moving contact 30 is sleeved on the rotor 22, or is mounted on the rotor 22 through a fastener, which is not exemplified here, and only the moving contact 30 can synchronously rotate along with the rotor 22.
Taking the example of switching the rotary disconnecting switch from the off state to the on state, in the off state, the magnetically controlled driving mechanism 12 stops operating, the rotor 22 is stationary relative to the base 21, and the moving contact 30 and the stationary contact 40 do not contact.
Referring to fig. 3 and fig. 4, when the switch from the off state to the on state is made, the magnetic control driving mechanism 12 operates, the magnetic rotator 11 rotates counterclockwise (here, the counterclockwise rotation of the magnetic rotator 11 is taken as an example) under the driving of the magnetic control driving mechanism 12, and the rotator 22 also rotates counterclockwise under the driving of the magnetic rotator 11. Because the second end of the rotator 22 extends into the rotation hole 211 of the base 21 and is rotatably coupled to the base 21, the rotator 22 is actually rotated counterclockwise with respect to the base 21. Regarding the connection mode of the rotating body 22 and the base 21, a groove may be formed in the base 21, and a protrusion may be provided on a side wall of the rotating body 22, or a connection piece similar to a bearing operating principle may be provided between the rotating body 22 and the base 21 so that the rotating body 22 and the base 21 may be rotatably connected. The present invention is not particularly limited herein.
When the rotator 22 rotates relative to the base 21, the moving contact 30 connected to the rotator 22 is driven to rotate together, so that the moving contact 30 moves in the direction of the fixed contact 40 of the rotary isolating switch. When the rotor 22 rotates to the preset position, the moving contact 30 contacts with the fixed contact 40, and the rotor 22 does not rotate in the counterclockwise direction any more, so that the rotary isolating switch is turned on. When the rotor 22 continues to rotate or rotates clockwise, the moving contact 30 is separated from the fixed contact 40 under the driving of the rotor 22, so as to realize the disconnection of the rotary isolating switch. The rotary isolating switch is switched on and off in a magnetic control mode, and can be switched on and off rapidly.
With continued reference to fig. 2 and 5, in some embodiments, the operating mechanism 20 further includes a limiting portion 221. The lateral wall of rotor 22 is located to spacing portion 221, and base 21 is equipped with spacing groove 212, and spacing groove 212 and rotation hole 211 intercommunication, the first end of rotor 22 is connected with magnetic rotator 11, and the second end of rotor 22 is rotated through rotation hole 211 and is connected with base 21, and spacing portion 221 stretches into spacing groove 212, and wherein, the rotation angle of spacing portion 221 in spacing groove 212 and rotation isolator's rotation angle looks adaptation.
When the rotary isolating switch is switched from the off state to the on state, the magnetic control driving mechanism 12 starts to operate, and the magnetic rotator 11 rotates anticlockwise under the driving of the magnetic control driving mechanism 12. The rotator 22 can rotate counterclockwise under the driving of the magnetic rotator 11, and the limiting part 221 arranged on the side wall of the rotator 22 also rotates in the limiting groove 212 along with the rotator 22. When the limit portion 221 abuts against the groove wall of the limit groove 212, and the limit portion 221 cannot continue to rotate anticlockwise along the limit groove 212, at this time, the moving contact 30 connected with the rotor 22 contacts with the fixed contact 40 of the rotary isolating switch, so that the rotary isolating switch is turned on. When the rotor 22 rotates clockwise, the moving contact 30 rotates clockwise under the driving of the rotor 22, i.e. the moving contact 30 moves away from the fixed contact 40, and when the limiting part 221 abuts against the limiting groove 212 again, the moving contact 30 and the fixed contact 40 are in a separated state, so as to realize the disconnection of the rotary isolating switch.
The limiting groove 212 is used for limiting the rotation angle of the limiting part 221, so that after the rotator 22 rotates clockwise or anticlockwise to a preset position, the rotator 22 can be abutted against the groove wall of the limiting groove 212, and the moving contact 30 connected with the rotator 22 is contacted with or separated from the fixed contact 40 of the rotary isolating switch under the driving of the rotator 22, so that the rotary isolating switch is turned on or turned off. The rotating body 22 can be prevented from rotating beyond the position of the fixed contact 40 due to the overlarge rotating angle in the rotating process, so that the moving contact 30 can not stop rotating at the preset position and is contacted with the fixed contact 40, and the rotary isolating switch is turned on. The conduction of the rotary isolating switch can be realized rapidly through the limit groove 212.
In some embodiments, the placement plane of the limit slot 212 is parallel to the rotational plane of the rotor 22, and the extension of the limit slot 212 within the placement plane forms an arc. The plane where the limiting groove 212 is located is set to be parallel to the rotating surface of the rotating body 22, so that the rotating body 22 can rotate conveniently, and the limiting groove 212 is set to be arc-shaped, so that the limiting part 221 of the rotating body 22 can be always located in the limiting groove 212 when the rotating body 22 rotates, and the probability that the limiting part 221 is separated from the limiting groove 212 is reduced.
In some embodiments, as shown in fig. 6 and fig. 7, the number of the operating mechanisms 20 is plural, the bases 21 of the operating mechanisms 20 are stacked in sequence, the rotating bodies 22 of the operating mechanisms 20 are connected in sequence in a linkage manner, the magnetic rotating body 11 can drive the rotating bodies 22 of the operating mechanisms 20 to rotate relative to the corresponding bases 21, and the rotating bodies 22 of the operating mechanisms 20 are used for being coupled with the moving contacts 30 of the rotary isolating switch one by one so as to drive the corresponding moving contacts 30 to move.
The rotating bodies 22 of the operating mechanisms 20 may be connected together by a fastener, or a groove may be formed in one of the rotating bodies 22, and the other rotating body 22 may be connected together by a clamping portion.
The magnetic control driving mechanism 12 is started, and the magnetic rotator 11 rotates under the driving of the magnetic control driving mechanism 12. The rotating body 22 connected with the magnetic rotating body 11 is also driven by the magnetic rotating body 11 to rotate, and other rotating bodies 22 connected with the rotating body 22 are also driven by the rotating body 22 to rotate, so that each rotating body 22 can simultaneously and coaxially rotate under the driving of the magnetic rotating body 11. The rotating bodies 22 can rotate and simultaneously drive the moving contacts 30 connected with the rotating bodies 22 to rotate together, so that the moving contacts 30 move towards the direction close to or away from the fixed contact 40 of the rotary isolating switch, and further the rotary isolating switch is turned on and off. And simultaneously controlling a plurality of moving contacts 30 can increase power.
Further, as shown in fig. 2, when the plurality of operating mechanisms 20 are operated simultaneously, the bases 21 of the plurality of operating mechanisms 20 are stacked. Each rotor 22 of the plurality of operating mechanisms 20 includes a rotation section 222 and a linkage key 223, a limiting portion 221 is provided on a side wall of the rotation section 222, the rotation section 222 is provided with a linkage key 223 groove extending along a rotation axis of the rotor 22, and the linkage key 223 groove is matched with the linkage key 223. The rotating bodies 22 of the plurality of operating mechanisms 20 of the rotating body 22 are rotatably connected to the corresponding bases 21 through the rotating sections 222, and the rotating bodies 22 of the plurality of operating mechanisms 20 are sequentially linked by the linking keys 223.
Wherein, the bases 21 of the operating mechanisms 20 are provided with through holes for the linkage keys 223 to pass through, and the linkage key 223 of the rotating body 22 of one operating mechanism 20 passes through the through hole of the base 21 of the other operating mechanism 20 between two adjacent operating mechanisms 20 and is inserted into the linkage key 223 groove of the rotating body 22 of the operating mechanism 20, thereby realizing the connection between the two adjacent rotating bodies 22. When the rotator 22 is mounted in the base 21, the rotating section 222 of the rotator 22 is inserted into the base 21, and the limiting portion 221 on the side wall of the rotating section 222 extends into the limiting groove 212 of the base 21, so that the rotator 22 and the base 21 are rotationally connected.
When the magnetic rotator 11 rotates, the rotator 22 connected with the magnetic rotator 11 can be driven to rotate, and the rotator 22 drives the other rotators 22 to rotate. The stopper 221 of the rotating section 222 of each rotating body 22 also rotates together with the rotating body 22 in the stopper groove 212 of the base 21. The limiting part 221 is arranged on the rotating section 222 of the rotating body 22, and the linkage key 223 groove is formed in the rotating section 222, so that the connection mode between the rotating bodies 22 is simplified.
As shown in fig. 2, in some embodiments, the magnetic rotator 11 is provided with a driving shaft 111 extending along the rotation axis of the magnetic rotator 11. The operating device further includes a coupling 23, one end of the coupling 23 is connected to the driving shaft 111, and the other end is connected to a linkage key 223 of a rotating body 22 of the plurality of operating mechanisms 20. When the magnetic rotator 11 rotates, the driving shaft 111 drives the coupling 23 to rotate, and the coupling 23 drives the rotating bodies 22 of the operating mechanisms 20 to rotate relative to the corresponding bases 21.
The drive shaft 111 of the magnetic rotator 11 is connected to the interlocking key 223 of the rotator 22 closest to the rotation shaft among the plurality of operating mechanisms 20 by a coupling, and the remaining operating mechanisms 20 are connected to each other by interlocking keys 223 of the respective rotators 22. When the magnetic rotator 11 rotates, the driving shaft 111 drives the coupling 23 to rotate, and the coupling 23 drives the rotating bodies 22 of the operating mechanisms 20 to rotate. The coupling 23 can play a role of buffering and damping to reduce vibration when the rotator 22 rotates, and improve stability when the rotator 22 rotates.
In some embodiments, the operating device further includes an arc-isolating member 24, where the arc-isolating member 24 is disposed between the rotating bodies 22 of two adjacent operating mechanisms 20 of the plurality of operating mechanisms 20. When the movable contact 30 and the stationary contact 40 are separated, an arc is generated, and the arc is prevented from being transferred from one rotor 22 to the other rotor 22 by the arc-separating member 24, and is influenced.
Wherein the rotor 22 of each operating mechanism 20 may be provided with an arc-separating member 24 to extinguish an arc generated when the moving contact 30 and the stationary contact 40 are separated. Wherein, the diameter of the rotating section 222 of the rotating body 22 is larger than that of the linkage key 223, and the arc isolating piece 24 can be sleeved at the joint of the rotating section 222 and the linkage key 223. When the arc barrier 24 is destroyed, replacement of the arc barrier 24 can be facilitated.
In some embodiments, the operating device further includes a handle 25, where the handle 25 is disposed at an end of the magnetic rotator 11 away from the rotator 22, and the handle 25 can rotate to drive the magnetic rotator 11 to rotate when rotating.
The operating means may be manually operated when the magnetically controlled drive mechanism 12 fails. The user rotates the handle 25, and the magnetic rotator 11 can be driven to rotate when the handle 25 rotates, so that the magnetic rotator 11 drives the rotator 22 to rotate, and the moving contact 30 is driven to move in a direction away from or close to the fixed contact 40, so that the disconnection and the connection of the rotary isolating switch are realized. Thus, when the magnetic control driving mechanism 12 is damaged, the operation mechanism 20 can not operate, and the application range of the operation device is enlarged.
Referring to fig. 9 and 11, in some embodiments, the operating device further includes a resilient member 26. The first end of the elastic member 26 is connected to the magnetic rotator 11, and the second end of the elastic member 26 is connected to the base 21. In particular, in this embodiment, the operating means may further comprise a support member 27, one end of the support member 27 being connectable to the magnetic swivel 11 and the other end being connectable to the coupling 23. The elastic member 26 may be sleeved on the outer wall of the supporting member 27. When the handle 25 rotates around the first rotation direction, the magnetic rotator 11 rotates along with the rotation of the handle 25, and drives the first end of the elastic element 26 to twist relative to the second end. When the handle 25 receives the force in the second rotation direction, the first end of the elastic member 26 drives the magnetic rotator 11 to rotate around the second rotation direction under the action of the elastic force.
Rotating the handle 25 causes the handle 25 to rotate about the first rotation direction, and the magnetic rotator 11 follows the handle 25 to rotate about the first rotation direction and drives the elastic member 26 to rotate. Since the first end of the elastic member 26 is connected to the magnetic rotator 11 and the second end of the elastic member 26 is connected to the base 21, the elastic member 26 generates an elastic force during rotation. When the handle 25 is not acted by external force, the magnetic rotator 11 is driven to rotate around the second rotation direction to return to the initial position by the elastic force of the elastic piece 26. The handle 25 connected to the magnetic rotator 11 and the rotator 22 are also driven by the magnetic rotator 11 to return to the initial position.
It will be understood that when the handle 25 rotates around the second rotation direction by a certain angle without any external force, the magnetic rotator 11, the rotator 22 and the handle 25 can be driven to rotate around the first rotation direction by the elastic force generated by the elastic member 26, which will not be described in detail herein.
The handle 25, the supporting piece 27 and the elastic piece 26 are matched to drive the operating mechanism 20 so that the moving contact 30 and the fixed contact 40 are in quick contact or separation, and quick opening and closing are achieved. Wherein, the opening and closing speed depends on the release speed of the elastic energy release. It should be noted that the supporting member 27 and the elastic member 26 may be configured according to different application scenarios. That is, the support 27 and the elastic member 26 may be optionally provided or not. If the support member 27 and the elastic member 26 are not required to be arranged, that is, a manual rapid opening and closing function is not required to be realized, the magnetic control assembly 10 drives the operating mechanism 20 to rapidly contact or separate, the rapid opening and closing speed depends on the action speed of the magnetic control assembly 10, the handle 25 can be reserved in the application scene, and the manual opening and closing can be realized when the magnetic control assembly 10 fails.
With continued reference to fig. 9, in some embodiments, the magnetic control driving mechanism 12 includes a first magnetic pole 121, a second magnetic pole 122, and a first magnetic yoke 123 connecting the first magnetic pole 121 and the second magnetic pole 122, where the first magnetic pole 121 and the second magnetic pole 122 enclose to form an annular structure with a gap, and the magnetic rotator 11 is disposed in the gap, and the first magnetic yoke 123 is circumferentially provided with a first coil 1231 along its own extending direction, so that the first magnetic pole 121 and the second magnetic pole 122 form opposite magnetism. ,

The first coil 1231 is used in cooperation with the first yoke 123, and the first coil 1231 is energized to make the first magnetic pole 121 and the second magnetic pole 122 magnetic, and the current direction in the first coil 1231 is determined by the winding manner of the first coil 1231 and the arrangement form of the magnetic rotator 11, which is not limited in this application. The first magnetic yoke 123, the first magnetic pole 121 and the second magnetic pole 122 together enclose to form an annular structure with a notch, and the annular structure may be a circular annular structure or a polygonal annular structure, wherein the notch of the annular structure is an accommodating space for installing the magnetic rotator 11. In use, the first coil 1231 is energized, while one of the first pole 121 and the second pole 122 forms an N pole and the other forms an S pole to drive the magnetic rotator 11 to rotate.
As shown in fig. 10, in some embodiments, the magnetic control assembly 10 further includes a second magnetic yoke 124, a first magnetic connecting portion 125 and a second magnetic connecting portion 126, where the second magnetic yoke 124 is in a ring structure, the first magnetic connecting portion 125 and the second magnetic connecting portion 126 are disposed inside the second magnetic yoke 124 and are oppositely disposed, the first magnetic connecting portion 125 is connected with a third magnetic pole 127, the second magnetic connecting portion 126 is connected with a fourth magnetic pole 128, and the first magnetic connecting portion 125 and the second magnetic connecting portion 126 are all provided with a second coil 129 along their own extending directions so that the third magnetic pole 127 and the fourth magnetic pole 128 form opposite magnetism.
In this embodiment, the second magnetic yoke 124 surrounds to form a closed ring structure for supplying current to the first magnetic connection portion 125 and the second magnetic connection portion 126, and the ring structure may be square ring shape as shown in fig. 10 or circular ring shape. The first magnetic connection 125 and the second magnetic connection 126 have opposite current directions. The two second coils 129 are respectively wound on the first magnetic connection portion 125 and the second magnetic connection portion 126, and the winding directions of the two second coils 129 are the same, so that the first magnetic pole 121 and the second magnetic pole 122 form opposite magnetism.
The outer periphery of the second yoke 124 in the embodiment of the present application has a complete magnetic circuit portion, so that the volume of the second yoke 124 increases, the magnetic circuit is less likely to saturate, and a larger electromagnetic force can be output. Note that, the second coil 129 cannot be disposed on the outer peripheral portion of the second yoke 124, and if the second coil 129 is disposed on the outer peripheral portion of the second yoke 124, the magnetic flux formed by the second coil 129 only forms a closed loop on the outer periphery of the yoke, and does not pass through the third magnetic pole 127 and the fourth magnetic pole 128, and the deflection of the magnetic rotator 11 cannot be ensured.

The rotating body 22 of the operating device is connected with the moving contact 30 to drive the moving contact 30 to move towards or away from the fixed contact 40.
Taking the example that the rotary isolating switch is switched from the off state to the on state, a forward current is applied to the magnetic control driving mechanism 12, so that the magnetic rotator 11 rotates anticlockwise and drives the rotator 22 to rotate anticlockwise. The rotor 22 rotates together with the moving contact 30 connected thereto. At this time, the moving contact 30 moves in a direction approaching the fixed contact 40. When the movable contact 30 contacts the fixed contact 40, the rotator 22 stops rotating, and the rotary isolating switch is turned on.
When the rotary isolating switch needs to be turned off, reverse current can be conducted to the magnetic control driving mechanism 12 so that the magnetic rotator 11 rotates clockwise. The magnetic rotator 11 drives the rotator 22 to rotate clockwise, and the moving contact 30 connected with the rotator 22 also rotates clockwise along with the pointer, so that the moving contact 30 and the fixed contact 40 are separated, and the disconnection of the rotary isolating switch is realized. And the movable contact 30 is connected with the rotating body 22, so that the damaged movable contact 30 can be replaced directly when the movable contact 30 is damaged, and the maintenance cost of the rotary isolating switch is reduced.

When the moving contact 30 is damaged, the moving contact 30 is conveniently removed from the rotor 22 to replace the damaged moving contact 30 with a new moving contact 30.
