[0052] In some embodiments, see Figure 3 and Figure 4 The circuit breaker interlocking unit 40 includes a first slide plate 41, a swing clamping member 42, a first swing connecting member 43 and a first limiting member 44. The first slide plate 41 is connected to the isolation drive shaft 21 and the circuit breaker drive shaft 31, and a clamping rod 411 is provided on the first slide plate 41. The swing clamping member 42 is connected to the isolation drive shaft 21, and the swing clamping member 42 has a clamping groove adapted to the clamping rod 411. The first swing connecting member 43 is connected to the circuit breaker drive shaft 31. The first limiting member 44 is provided on the first slide plate 41, and is used to limit the first swing connecting member 43. Specifically, a circuit breaker operating handle 45 is provided at the other end of the circuit breaker drive shaft 31. In this embodiment, by providing a clamping rod 411 on the first slide plate 41, and providing a clamping groove adapted to the clamping rod 411 on the swing clamping member 42, the swing clamping member 42 is clamped on the first slide plate 41, so as to limit and fix the first slide plate 41.

[0054] When the isolating switch is in the closed state, the swing clamping plate is disconnected from the clamping rod 411, and the first slide plate 41 can move freely. At this time, the first limiter 44 cannot limit the rotation of the first swing connector 43 and the circuit breaker drive shaft 31. The circuit breaker operating handle 45 is pulled in the direction indicated by the circuit breaker closing indicator mark 452 on the circuit breaker operating handle 45 to drive the circuit breaker to close. After the circuit breaker is closed, the circuit breaker operating handle 45 is released, and the circuit breaker drive shaft 31 is reset under the drive of the operating mechanism. At this time, the operating handle is pulled in the reverse direction in the direction indicated by the circuit breaker opening indicator mark 451 on the circuit breaker operating handle 45 to drive the circuit breaker to open.
[0055] Preferably, the first slide plate 41 is provided with an oblong hole arranged in the vertical direction, and the position of the first slide plate 41 in the vertical direction can be adjusted.

[0057] When the circuit breaker is in the closed state, the fixed plate 521 presses the limit shaft 511 on the second slide plate 51, and the second slide plate 51 cannot move. The second limit member 54 on the second slide plate 51 presses the second swing connection member 53, so that the isolation drive shaft 21 cannot rotate, thereby preventing the isolation switch from being accidentally closed when the circuit breaker is in the open state.
[0058] When the circuit breaker is in the open state, the fixing plate 521 releases the fixing of the second slide plate 51, and the second slide plate 51 can move freely. At this time, the second limiter 54 cannot limit the rotation of the second swing connector 53 and the isolation drive shaft 21. The isolation operating handle 55 is pulled in the direction indicated by the isolation switch closing indicator mark 552 on the isolation operating handle 55 to drive the isolation switch to open. After the isolation switch is opened, the clamping rod 411 of the first slide plate 41 is clamped in the clamping groove of the swing clamping member 42, and the circuit breaker cannot be closed at this time.

[0061] In some embodiments, see Figure 2 and Figure 5 , a avoidance groove 524 is provided on the fixed plate 521. Specifically, the avoidance groove 524 has a certain length in the vertical direction. When the circuit breaker is in the open state, the fixed plate 521 moves until the limit shaft 511 is located in the avoidance groove 524. At this time, the fixed plate 521 releases the limit fixation of the second slide plate 51, and the second slide plate 51 can move freely.
