The electrical switch 100 refers to a switching device capable of closing, carrying and breaking current under normal circuit conditions and closing, carrying and breaking current under abnormal circuit conditions within a specified time. Rotary isolating switch Take the commonly used rotary isolating switch as an example. The rotary isolating switch usually includes an operating system, a contact system, an arc extinguishing system, etc., wherein the turning on or off of the rotary isolating switch is realized by the contact or separation of the moving contact 30 and the static contact 40 in the contact system, The arc extinguishing system is used to extinguish the arc generated by breaking the moving contact 30 and the static contact 40, and the operating system is used to control the contact system to close or open.

After the current rotary isolating switch has been in operation for a period of time, it is prone to the phenomenon that the circuit cannot be disconnected in time, or the circuit needs to be repeatedly operated to disconnect the circuit.

In view of this, the present application provides an operating device for an electrical switch. As shown in FIGS. 1 and 2 , the operating device for electrical switches includes a magnetic control assembly 10 and an operating mechanism 20 . The magnetic control assembly 10 includes a magnetic rotor 11 and a magnetic control driving mechanism 12 for driving the magnetic rotor 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. The first end of the rotating body 22 is connected to the magnetic rotor 11, and the second end of the rotating body 22 is connected to the base 21 through the rotating hole 211. Turn to connect. Wherein, the rotating body 22 is used for coupling with the movable contact 30 of the electrical switch 100 , and the rotating body 22 can rotate following the rotation of the magnetic rotating body 11 to drive the moving contact 30 of the electrical switch 100 to move.

The operating device will be described below in conjunction with the use process of the operating device.

Taking the use of a rotary isolating switch as the electrical switch 100 as an example, please refer to FIGS. 1 and 2 , the magnetic control drive mechanism 12 can drive the magnetic rotor 11 to rotate clockwise or counterclockwise. The first end of the rotating body 22 is connected to the magnetic rotating body 11 , and the other end extends into the rotating hole 211 of the base 21 and is connected to the base 21 in rotation. Among them, the rotating body 22 is used to couple with the moving contact 30 of the rotary isolating switch. Regarding the connection relationship between the two, the moving contact 30 can be sleeved on the rotating body 22, or installed on the rotating body 22 through fasteners, etc. , not exemplifying them one by one here, it is only necessary to enable the movable contact 30 to rotate synchronously with the rotating body 22 .

Take the switch of the rotary isolating switch from the off state to the on state as an example. In the off state, the magnetic control drive mechanism 12 stops running, the rotating body 22 is stationary relative to the base 21, and the moving contact 30 and the static contact 40 do not move. touch.

Please refer to Fig. 3 and Fig. 4, when switching from the off state to the on state, the magnetic control drive mechanism 12 runs, and the magnet rotor 11 rotates counterclockwise under the drive of the magnet control drive mechanism 12 (here, the magnet rotor 11 counterclockwise clockwise rotation as an example), the rotating body 22 also rotates counterclockwise under the drive of the magnetic rotor 11. Because the second end of the rotating body 22 protrudes into the rotating hole 211 of the base 21 and is rotatably connected with the base 21 , the rotating body 22 actually rotates counterclockwise relative to the base 21 . Regarding the connection mode of the rotating body 22 and the base 21, a groove can be provided in the base 21, and a protrusion is provided on the side wall of the rotating body 22, or a connection between the rotating body 22 and the base 21 can be provided. The working principle of the bearing is similar to that of the connection so that the rotating body 22 can be rotationally connected with the base 21 . No specific limitation is made here.

When the rotating body 22 rotates relative to the base 21 , it can drive the moving contact 30 connected with the rotating body 22 to rotate together, so that the moving contact 30 moves toward the static contact 40 of the rotary isolating switch. When the rotating body 22 rotates to the preset position, the movable contact 30 contacts the static contact 40, and the rotating body 22 does not continue to rotate counterclockwise, so as to realize the conduction of the rotary isolating switch. When the rotating body 22 continues to rotate or rotates clockwise, the movable contact 30 is separated from the static contact 40 driven by the rotating body 22, thereby realizing the disconnection of the rotary isolating switch. The turn-on and break-off of the rotary isolating switch is realized by means of magnetic control, and the closing and breaking of the rotary isolating switch can be realized quickly.

Please continue to refer to FIG. 2 and FIG. 5 , in some embodiments, the operating mechanism 20 further includes a limiting portion 221 . The limiting part 221 is arranged on the side wall of the rotating body 22, the base 21 is provided with a limiting groove 212, the limiting groove 212 communicates with the rotating hole 211, the first end of the rotating body 22 is connected with the magnetic rotor 11, and the rotating body 22 The second end is rotatably connected to the base 21 through the rotation hole 211, and the limiting part 221 extends into the limiting groove 212, wherein the rotation angle of the limiting part 221 in the limiting groove 212 is suitable for the rotation angle of the rotary isolating switch match.

When the rotary isolating switch is switched from the off state to the on state, the magnetic control drive mechanism 12 starts to run, and the magnetic rotor 11 rotates counterclockwise under the drive of the magnetic control drive mechanism 12 . The rotating body 22 can rotate counterclockwise driven by the magnetic rotating body 11 , and the limiting portion 221 disposed on the side wall of the rotating body 22 also rotates in the limiting groove 212 following the rotating body 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 counterclockwise along the limit groove 212, at this time, the movable contact 30 connected to the rotating body 22 and the rotary isolating switch The static contacts 40 of the rotary disconnector are in contact with each other, so as to realize the conduction of the rotary isolating switch. When the rotating body 22 rotates clockwise, the movable contact 30 rotates clockwise under the drive of the rotating body 22, that is, the moving contact 30 moves away from the static contact 40, when the limiting part 221 and the limiting groove 212 again When abutting against each other, the movable contact 30 and the static contact 40 are in a separated state, thereby realizing the disconnection of the rotary isolating switch.

The rotation angle of the limiting part 221 is limited by the limiting groove 212, so that after the rotating body 22 rotates clockwise or counterclockwise to the preset position, it can abut against the groove wall of the limiting groove 212, so that it is compatible with the rotation The movable contact 30 connected to the body 22 is driven by the rotating body 22 to contact or separate from the static contact 40 of the rotary isolating switch, thereby realizing the conduction or disconnection of the rotary isolating switch. It can avoid that during the rotation of the rotating body 22, due to the excessive rotation angle, the moving contact 30 connected with the rotating body 22 stops rotating beyond the position where the static contact 40 is located, so that the moving contact 30 cannot be rotated at the preset position. The position stops rotating and contacts with the static contact 40, thereby realizing the conduction of the rotary isolating switch. Through the limiting groove 212, the conduction of the rotary isolating switch can be quickly realized.

In some embodiments, the setting plane of the limiting slot 212 is parallel to the rotating plane of the rotating body 22 , and the extension of the limiting slot 212 in the setting 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, which is convenient for the rotating body 22 to rotate, and the limiting groove 212 is arranged in an arc shape, so that when the rotating body 22 rotates, the limit of the rotating body 22 The positioning portion 221 can always be located in the limiting groove 212 to reduce the probability of the limiting portion 221 coming out of the limiting groove 212 .

In some embodiments, as shown in FIG. 6 and FIG. 7 , there are multiple operating mechanisms 20 , the bases 21 of the multiple operating mechanisms 20 are stacked in sequence, and the rotating bodies 22 of the multiple operating mechanisms 20 are sequentially linked and connected. , the magnetic rotor 11 can drive the rotating bodies 22 of the multiple operating mechanisms 20 to rotate relative to the corresponding base 21, and the rotating bodies 22 of the multiple operating mechanisms 20 are used to couple with the multiple moving contacts 30 of the rotary isolating switch one by one, to drive the corresponding moving contact 30 to move.

The rotating bodies 22 of the above-mentioned operating mechanisms 20 can be connected together by a buckle, or a groove can be provided on one of the rotating bodies 22, and a locking part can be provided on the other rotating body 22 to be connected together.

The magnetic control drive mechanism 12 is started, and the magnetic rotor 11 rotates under the drive of the magnetic control drive mechanism 12 . Wherein, the rotating body 22 connected with the magnetic rotating body 11 also rotates under the driving of the magnetic rotating body 11, and other rotating bodies 22 connected with the rotating body 22 also rotate under the driving of the rotating body 22, therefore, Driven by the magnetic rotor 11 , each rotating body 22 can rotate coaxially at the same time. When each rotating body 22 rotates, it can drive the moving contact 30 connected with each rotating body 22 to rotate together, so that each moving contact 30 moves toward or away from the static contact 40 of the rotary isolating switch, thereby realizing rotary isolation Switch on and off. Moreover, controlling a plurality of movable contacts 30 at the same time can increase power.

Further, as shown in FIG. 2 , when multiple operating mechanisms 20 operate simultaneously, the bases 21 of the multiple operating mechanisms 20 are stacked. Each rotating body 22 of a plurality of operating mechanisms 20 includes a rotating section 222 and a linkage key 223, the side wall of the rotating section 222 is provided with a limit portion 221, and the rotating section 222 is provided with a linkage key 223 slot extending along the rotation axis of the rotating body 22 , the linkage key 223 groove matches the linkage key 223. The rotating bodies 22 of the plurality of operating mechanisms 20 of the rotating body 22 are rotationally connected to the corresponding base 21 through the rotating section 222 , and the rotating bodies 22 of the plurality of operating mechanisms 20 are sequentially connected in linkage through the linkage key 223 .

Wherein, the bases 21 of a plurality of operating mechanisms 20 are provided with through holes for the interlocking key 223 to pass through. Between two adjacent operating mechanisms 20, the interlocking key 223 of the rotating body 22 of one operating mechanism 20 passes through the other. The through hole of the base 21 of the operating mechanism 20 is inserted into the slot of the linkage key 223 of the rotating body 22 of the operating mechanism 20 , so as to realize the connection between two adjacent rotating bodies 22 . When the rotating body 22 is installed in the base 21, the rotating section 222 of the rotating body 22 is inserted into the base 21, and the limiting part 221 of the side wall of the rotating section 222 extends into the limiting groove 212 of the base 21, thereby realizing the rotation of the rotating body. 22 and the rotation connection of base 21.

When the magnetic rotor 11 rotates, it can drive the rotating body 22 connected with the magnetic rotating body 11 to rotate, and the rotating body 22 drives the remaining rotating bodies 22 to rotate. The limiting portion 221 of the rotating segment 222 of each rotating body 22 also rotates in the limiting groove 212 of the base 21 together with the rotating body 22 . The position limiting part 221 is arranged on the rotating section 222 of the rotating body 22 , and a linkage key 223 slot is provided in the rotating section 222 , which simplifies the connection between the rotating bodies 22 .

As shown in FIG. 2 , in some embodiments, the magnetic rotor 11 is provided with a drive shaft 111 extending along the rotation axis of the magnetic rotor 11 . The operating device further includes a shaft coupling 23 , one end of which is connected to the drive 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 .

The drive shaft 111 of the magnetic rotor 11 is connected to the linkage key 223 of the rotating body 22 closest to the rotating shaft among the plurality of operating mechanisms 20 through a coupling, and the remaining operating mechanisms 20 are connected through the linkage keys 223 of their respective rotating bodies 22 stand up. When the magnetic rotor 11 rotates, the drive shaft 111 can drive the coupling 23 to rotate, and the coupling 23 drives the rotating bodies 22 of the plurality of operating mechanisms 20 to rotate. The coupling 23 can play a role of buffering and shock absorption, so as to reduce the vibration when the rotating body 22 rotates, and improve the stability of the rotating body 22 when rotating.

In some embodiments, the operating device further includes an arc-breaker 24 , and the arc-breaker 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 static contact 40 are separated, an arc will be generated, and the arc barrier 24 can prevent the arc from being transmitted from one rotating body 22 to the other rotating body 22 and affecting it.

Wherein, the rotating body 22 of each operating mechanism 20 can be provided with an arc breaker 24 to extinguish the arc generated when the moving contact 30 and the static contact 40 are separated. Wherein, the diameter of the rotating section 222 of the rotating body 22 is larger than the diameter of the interlocking key 223 , and the arc-breaker 24 can be sleeved at the joint between the rotating section 222 and the interlocking key 223 . When the arc breaker 24 is damaged, it is convenient to replace the arc breaker 24 .

In some embodiments, the operating device further includes a handle 25 . The handle 25 is disposed on the end of the magnetic rotor 11 away from the rotating body 22 . When the handle 25 rotates, it can drive the magnetic rotating body 11 to rotate.

When the magnetic control drive mechanism 12 breaks down, the operating device can be manually operated. When the user turns the handle 25, the magnetic rotor 11 can be driven to rotate through the rotation of the handle 25, thereby driving the rotor 22 to rotate through the magnetic rotor 11, so as to drive the moving contact 30 to move away from or close to the static contact 40, and then Realize the disconnection and conduction of the rotary isolating switch. In this way, when the magnetic control driving mechanism 12 is damaged, the operating mechanism 20 cannot be operated, which expands the scope of use of the operating device.

Please refer to FIG. 9 and FIG. 11 , in some embodiments, the operating device further includes an elastic member 26 . A first end of the elastic member 26 is connected to the magnetic rotor 11 , and a second end of the elastic member 26 is connected to the base 21 . Specifically, in this embodiment, the operating device may further include a support member 27 , one end of the support member 27 may be connected to the magnetic rotor 11 , and the other end may be connected to the shaft coupling 23 . The elastic member 26 can be sleeved on the outer wall of the supporting member 27 . When the handle 25 rotates around the first rotation direction, the magnetic rotor 11 rotates following the rotation of the handle 25 and drives the first end of the elastic member 26 to twist relative to the second end. When the handle 25 receives force in the second rotation direction, the first end of the elastic member 26 drives the magnetic rotor 11 to rotate around the second rotation direction under the action of the elastic force.

Turning the above-mentioned handle 25 can make the above-mentioned handle 25 rotate around the first rotation direction, and the magnetic rotor 11 follows the handle 25 to rotate around 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 rotor 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 subjected to external force, the magnetic rotor 11 is driven by the elastic force of the elastic member 26 to rotate around the second rotation direction and return to the initial position. The handle 25 and the rotating body 22 connected with the magnetic rotor 11 also return to the initial position under the drive of the magnetic rotor 11 .

It can be understood that when the handle 25 rotates around the second rotation direction for a certain angle and is no longer subjected to external force, under the action of the elastic force generated by the elastic member 26, the magnetic rotor 11, the rotor 22 and the handle 25 can also be driven to rotate around The first rotation direction rotates, which will not be described in detail here.

Through the cooperation of the handle 25 , the supporting member 27 and the elastic member 26 , the operating mechanism 20 is driven to make the movable contact 30 and the static contact 40 contact or separate quickly, thereby realizing quick opening and closing. Among them, the opening and closing speed depends on the release speed of elastic energy release. It should be noted that the supporting member 27 and the elastic member 26 can be set according to different application scenarios.
