35kV And Below Hv Lv Switchgear Information

35KV complete set of high voltage cabinet Inflatable cabinet Switch cabinet KYN middle cabinet XGN ring network cabinet is suitable for AC 50HZ,10KV network as the breaking load and short circuit and close short circuit current, the ring network cabinet is equipped with manual, electric spring mechanism to operate the load switch, grounding switch isolation switch is equipped with manual operation mechanism.

Structure and working principle
The ring network cabinet is made of air as the insulating medium, mainly equipped with ZFN-10 vacuum load switch, the main scheme has the inlet cabinet and outlet cabinet.
Inlet cabinet scheme: there is a ZFN-10 vacuum load switch in the main circuit of the cabinet, which is equipped with an isolation knife and, as appropriate, is also equipped with a grounding knife. The three are installed on a rack and interlocked. Therefore, it can realize the operation of the three stations of connecting the bus, isolating and grounding, and the cabinet can also flexibly assemble CT, PT and other components.
Outlet cabinet solution: the main circuit in the cabinet is composed of a ZFN-10 vacuum load switch and a fuse with an impinger (which has the function of an isolating switch) and a ground knife, which can also realize three-station operation, and the cabinet can also flexibly assemble CT, PT and ZNO arrester and other components. Therefore, the measuring cabinet can sometimes be omitted.

The inlet and outlet cabinets are equipped with insulation protective partitions interlocked with ground switches. The switches in the cabinets are interlocked with partitions and cabinet doors by mechanical interlocks, which meet the requirements of "five defenses". The protection level of the cabinet shell is IP2X.
