Embodiment Construction

[0038] refer to figure 1 , The circuit breaker 1 is installed in the drawer seat 2, and there are three working positions, namely separation, test and connection. When it is in the separated position, the circuit breaker 1 and the drawer base 2 are completely separated from each other, and the circuit breaker can be pulled out from the drawer base and removed, and the circuit breaker can be inspected, maintained or replaced; when it is in the test position, the circuit breaker 1 Only the secondary circuit is connected with the drawer seat 2, and some action checks can be made on the circuit breaker before it is put into operation; when it is in the connection position, the primary and secondary circuits between the circuit breaker 1 and the drawer seat 2 are completely connected, works fine.

[0039] figure 2 The structural diagram of the drawer seat is shown, and the entire structural diagram can be clearly seen. The circuit breaker 1 is installed on the left and right ma...
