-
HXGN AC high-voltage sulfur hexafluoride ring network switchgear (hereinafter referred to as ring network cabinet) is a new generation of high-voltage electrical products successfully developed by our company by introducing foreign advanced technology and according to the requirements of domestic household appliances and urban network transformation.
After strict type test and long-term trial operation assessment, all technical performance indexes have reached the national standard. The main switch, operating mechanism and components of the unit cabinet adopt FLN36 SF6 switchgear independently produced by our company, and its operation modes are divided into manual and electric.
The cabinet body is made of aluminum-coated zinc plate and riveted by CNC machine tools, and has reliable mechanical interlocking and misoperation prevention functions. This product is characterized by small size, light weight, beautiful appearance, simple operation, long service life, high parameters, no pollution and less maintenance.
It is widely used in industrial and mining enterprises, high-rise buildings, residential quarters, schools, etc. as the ring network power supply and terminal power distribution of power distribution system.
A sulfur hexafluoride load switch or a combination of sulfur hexafluoride load switch and fuse is installed in the ring network cabinet, which can switch on and off the rated load current, rated short-circuit current and no-load current of transformer. After the combination is equipped with fuse, the short-circuit current of 31.5kA can be switched off for a second time, which plays a control and protection role in the power system.
