Further, the connecting member 121 is movably disposed outside the cabinet 200, and one end of the connecting member 121 away from the operating assembly 110 is connected to the circuit breaker through the driving hole; the operating assembly 110 is rotatably disposed on the cabinet 200 and connected to the switch 300.

The circuit breaker is arranged in the cabinet body 200, the switch 300 is arranged on the cabinet body 200, the interlocking device 100 is arranged outside the cabinet body 200, one end of the connecting piece 121 far away from the operating assembly 110 is connected to the circuit breaker through a driving hole, and the operating assembly 110 is rotatable on the cabinet body 200 and connected to the switch 300. The circuit breaker is opened, the connecting piece 121 moves along the first direction to the direction back to the operating component 110, at this time, the operating component 110 exposes the operating position 111, and the operator can use the operating position 111 to operate the switch piece 300; when the circuit breaker is switched on and the connecting part 121 moves towards the operating assembly 110 along the first direction, the connecting part 121 can cover the operating position 111 on the operating assembly 110, so that the operator cannot continuously use the operating position 111 to operate the switch 300, and misoperation of the operator is prevented. Meanwhile, the blocking member 122 disposed at one end of the connecting member 121 close to the operating assembly 110 moves along with the connecting member 121 and is blocked in the limiting groove 112 of the operating assembly 110, thereby preventing the operating assembly 110 from rotating to start the switch member 300.

Referring to fig. 2 and 3, in one embodiment, the interlock device 100 of the switch cabinet further includes a limiting assembly, the limiting assembly is configured to be movably disposed outside the cabinet 200 and connected to the circuit breaker through a driving hole, the limiting assembly is located at a side of the connecting member 121 opposite to the operating assembly 110, the limiting assembly is capable of moving along a second direction relative to the cabinet 200, the second direction is intersected with the first direction, and an end of the connecting member 121 opposite to the operating assembly 110 is capable of abutting against the limiting assembly along the first direction.

In the open state of the circuit breaker, the limiting assembly moves in the positive direction (as shown in B in fig. 2) along the second direction, at this time, the connecting member 121 and the limiting assembly are arranged in a staggered manner in the first direction, and the connecting member 121 moves in the positive direction (as shown in a in fig. 2) along the first direction, so that the connecting member 121 is clamped on one side of the limiting assembly facing the negative direction of the second direction, and the limiting assembly cannot move in the negative direction of the first direction; the connecting member 121 can move in the forward direction of the first direction, so that the connecting member 121 releases the covering of the operation position 111, and the blocking member 122 exits from the limiting groove 112. The switching element 300 is driven by the operating position 111, so that the switching element 300 is switched from the isolation state to the closing state. Then, the connecting element 121 is moved in the negative direction of the first direction, the connecting element 121 covers the operating position 111, and the locking element 122 is locked in the limiting groove 112, thereby ensuring that the switch element 300 is in a closing state. At this moment, the circuit breaker is switched on, and the limiting assembly is driven to move along the negative direction of the second direction, so that the limiting assembly abuts against one side, facing the positive direction of the first direction, of the connecting piece 121, and the connecting piece 121 cannot move along the positive direction of the first direction. The limiting assembly and the connecting member 121 limit each other in the first direction and the second direction, so that the interlocking device 100 has stable structural limitation in the opening state and the closing state of the circuit breaker, and the safety and the reliability of the interlocking device 100 are ensured.

Referring to fig. 5, in particular, the limiting assembly includes a rotating member 131, a transmission member 132 and a limiting member 133, the rotating member 131 is configured to be rotatably disposed on the cabinet 200 and pass through the driving hole to be connected to the circuit breaker, one end of the transmission member 132 is connected to the rotating member 131, the other end of the transmission member 132 is connected to the limiting member 133, the transmission member 132 is configured to drive the limiting member 133 to move along the first direction, and the connecting member 121 can abut against the limiting member 133.

As shown in fig. 2, in the present embodiment, in the open state of the circuit breaker, the circuit breaker drives the rotating member 131 to rotate counterclockwise, so that the rotating member 131 drives the transmission member 132 to move the limiting member 133 away from the rotating member 131. At this time, the link 121 and the stopper 133 are disposed in a staggered manner, and the link 121 is moved in a direction to approach the rotator 131 so that one end of the link 121 is positioned on the side of the stopper 133 to approach the rotator 131. Meanwhile, the connecting member 121 releases the covering of the operation position 111, and the locking member 122 exits the limiting groove 112, so that the operation position 111 can be operated, and the operation assembly 110 can rotate on the cabinet 200.

As shown in fig. 3, when the operating assembly 110 drives the switch 300 to be adjusted from the isolated state to the closed state, the connecting member 121 moves along the first direction, so that one end of the connecting member 121 away from the limiting member 133 covers the switch hole, and the connected locking member 122 is locked in the limiting groove 112, so that the operating assembly 110 cannot be operated continuously and cannot rotate on the cabinet 200. After the above operation, the circuit breaker is switched on, and when the circuit breaker drives the rotating member 131 to rotate clockwise, the rotating member 131 drives the transmission member 132 to move the limiting member 133 toward the rotating member 131. At this time, the limiting member 133 can abut against a side of the connecting member 121 opposite to the operating member 110, so that the operating member 110 cannot rotate, the connecting member 121 cannot move, and stability and safety of a closing state are ensured.

When the rotating member 131 rotates, the transmission member 132 compresses the first elastic member 134, so that the limiting member 133 of the first elastic member 134 is pushed away from the rotating member 131. At this time, one end of the connecting element 121 away from the operating element 110 abuts against one side of the limiting element 133 close to the rotating element 131, so that the limiting element 133 cannot move toward the rotating element 131 under the elastic force of the first elastic element 134. Meanwhile, the limiting member 133 is tightly abutted to the connecting member 121 under the elastic force of the first elastic member 134, so that the limiting function of the connecting member 121 on the limiting member 133 is more stable, and the safety and stability of the interlock device 100 in the opening state of the circuit breaker are ensured.

The first elastic member 134 is connected to the position limiting portion by a connecting portion 1331 penetrating the moving hole 1351, so that the elastic force of the first elastic member 134 is more stable when acting on the position limiting portion through the connecting portion 1331. Specifically, the moving hole 1351 is a rectangular hole, and the connecting portion 1331 is a cube. Connecting portion 1331 of cube shape wears to locate the removal hole 1351 of rectangle, and connecting portion 1331 can not take place to rotate in removing hole 1351 for connecting portion 1331 can set up on spacing portion more steadily, has improved interlock 100's stability.
