Summary:

Hxgn15a-12 box type fixed AC metal enclosed ring network switchgear (hereinafter referred to as "ring network cabinet"),

It is a new type of switchgear designed for the transformation and construction of urban power grid. It is also used as on in the power supply system

Load breaking current and short-circuit current are applicable to AC 3-10kV and 50Hz distribution system. widely

It is widely used in urban power grid construction and transformation projects, industrial and mining enterprises, high-rise buildings and public facilities. As ring network power supply unit and terminal equipment, it plays the role of power distribution, control and protection of electrical equipment. It can also be installed in pre installed substations. The ring main cabinet is equipped with vacuum load switch and spring operating mechanism, which can be operated manually or electrically. The grounding switch and disconnector are equipped with manual operating mechanism. The ring main cabinet has strong integrity, small volume, no combustion and explosion hazards, and has reliable "five prevention" function

Comply with GB / t3906, GB / t3804 and other relevant national standards

Main features:

The ring main cabinet is equipped with fzn12-12d load switch or fzrn12-12d fuse combination

Type a electrical appliance is equipped with disconnector, vacuum load switch and grounding switch, and the disconnector and grounding switch have obvious fractures.

The disconnector, vacuum load switch, grounding switch and cabinet door have perfect and reliable mechanical interlocking, which can effectively prevent misoperation and ensure safe maintenance. It can be operated manually and electrically.

Fuse combined electrical cabinet and fuse tube are equipped with striker. In case of short circuit, the striker strikes the tripping mechanism to realize rapid disconnection and effectively protect electrical equipment. The ring main cabinet adopts front operation and reliable wall installation.
