Product structure features

The overhaul structure is miniaturized, reducing the space occupied by 40-60% compared with the volume of the traditional vacuum circuit breaker switch cabinet, saving the total investment of power engineering.

Save switch housing and cabinet connection discharge materials, products more energy - saving and environmental protection.

The overhauling switch cabinet comprises a bus room, a meter room, a primary main component room, and an incoming and outgoing cable room.

Each compartment with partition and batons mutual isolation, busbar chamber, circuit breaker room, cable terminal room three high pressure chamber has upward pressure relief devices, used for internal arc occurs, discharge arc pressure, to ensure safety.

Outlet and inlet line of mixer set isolating switch, vacuum circuit breaker, switchgear earthing knife (isolation), equipped with reliable interlocking, among the isolator has obvious fracture, can be observed clearly switch state.

The overhauling operating mechanism USES a new type of mechanism to achieve the functional requirements of "five prevention" by means of mandatory mechanical locking, which has the features of simple operation, safety and reliability.

The full-metal sealing design of the pontoon cabinet body ensures reliable grounding, and the top of the cabinet is provided with a pressure relief opening with an empty seal

The inspection cabinet body is equipped with imported aluminium-zinc-coated forming products with high mechanical strength.
