&.Composition structure of distribution cabinet:
The switchgear cabinet structure adopts assembled type, the circuit breaker adopts handcart floor-standing structure, equipped with a new composite insulated vacuum circuit breaker, and has good interchangeability handcart frame It is equipped with a screw nut propulsion mechanism, which can easily move the handcart and prevent damage to the propulsion mechanism caused by misoperation. The interlocking between the main switch, the handcart and the switch cabinet door adopts a forced mechanical locking method to meet the "five prevention" functions. All operations can be carried out with the cabinet door closed. There is ample space in the cable compartment, and multiple cables can be connected. The quick grounding switch is used for grounding and circuit short circuit.
