Its& switchgear cabinet structure adopts assembled type, and the circuit breaker adopts handcart floor-standing structure, equipped with a new type of composite insulated vacuum circuit breaker, and has good interchangeability. It is installed in the handcart frame. The screw nut propulsion mechanism 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 for all operations. The cable compartment has ample space and can be connected to multiple cables. The quick grounding switch is used for grounding and loop short circuit. The protection level of the housing is high when the door of the handcart compartment is open. .High voltage distribution switchgear
