Zhejiang Hengkong Electric Co., Ltd

VHK9S-12GD series high-voltage miniaturized air-insulated switchgear is a new generation of indoor miniaturized complete power distribution device for 6~12KV, three-phase AC 50Hz power distribution system. It is mainly used in photovoltaic, wind power, industrial and mining enterprises, residential areas, urban complexes and other power distribution systems, and its fixed, miniaturized, integrated and modular characteristics are especially suitable for places with narrow and limited installation locations (power distribution rooms, prefabricated substations, underground garages, etc.), and the 10kV system single cabinet (width 450mm * depth 950mm * height 1750mm) can be completely frontally maintained. The standard VHK9S-12GD series indoor high-voltage vacuum circuit breaker has excellent electrical and mechanical properties.
▷ Adopt solid seal pole technology
▷ The product adopts modular design: frame structure, integrating disconnector, sealed vacuum circuit breaker, grounding switch, interlocking mechanism, and operating mechanism as one of the high-performance miniaturized high-voltage electrical products;
▷ The minimum width of the cabinet can reach 450mm, and the width can be customized according to user needs 500mm, 550mm, 600mm, 800mm and other specifications, and the scheme is flexible. ▷ Rotary disconnector with visible fracture after opening:
▷ There is a forced mechanical interlock between the isolation switch, circuit breaker and grounding switch to prevent misoperation: ▷ The circuit breaker adopts a pure modular operating mechanism, which can be replaced or overhauled independently, and has good interchangeability. It can be operated manually, or AC and DC energy storage can be used to achieve remote control; ▷ In the switch cabinet structure, the bus room and the cable room can be separated by a metal partition
▷ The cabinet door and grounding switch are designed with a reliable interlocking structure to ensure the safety of operators
