Sichuan Chengdu HXGN-12 High Voltage Cabinet Manufacturer - Xindun Electric

The basic composition of the high-voltage cabinet produced by Xindun Electric, the manufacturer of HXGN-12 high-voltage cabinet in Chengdu, Sichuan:

The ring main unit is generally composed of switch Room, fuse room, operating mechanism room and Cable The chamber (underframe) is composed of four parts. The switch room is composed of various functional circuits (including grounding switch and load switch) sealed in the metal shell and the bus between the circuits. The shell is rolled by steel plate (or stainless steel plate). Each functional circuit includes a load switch and grounding switch. The load switch is composed of a vertically moving moving contact system and a static contact located at the lower end. When the switch is closed, the moving contact moves downward and the load switch is connected. The grounding switch is composed of dynamic contact knife and static contact knife Spring During the movement, the grounding switch is quickly connected. There are 4 rectangular assembly process holes at the upper and rear of the switch room, and the front of the ring main unit is equipped with observation window The "open" and "close" positions of the grounding switch can be seen. Explosion proof devices are installed at the rear of the ring main unit.

The load switch adopts the compressed air internal blowing structure, with strong arc extinguishing ability, and does not affect the insulation between phases and to the ground. The moving and static contacts are equipped with arc contacts, which greatly improves the breaking times. The fuse and the load switch room constitute the transformer protection circuit. The high-voltage current limiting fuse is installed in the epoxy casting insulation housing. After the fuse is fused, the striker pops up and the load switch opens.
