Model meaning
Main technical parameters
Working principle
1.Incoming cabinet scheme
The main circuit of the cabinet is provided with a FZN21-12/630 type vacuum load switch, which is provided with an isolating knife, and can also be equipped with a grounding knife. The three parts are assembled on a machine frame and are interlocked with each other. So it can be achieved through the bus, isolation, grounding operation of the three stations, cabinets can also be flexibly equipped with CT, PT and other components.
2.Outlet cabinet scheme
The main circuit of the cabinet is composed of a FZN21-12/630 type vacuum load switch and a fuse with an impact device (with the function of an isolating switch) and a grounding knife, and the three station operation can also be realized. The cabinet can also be flexibly equipped with CT/PT lightning arrester and other components, so sometimes can be omitted metering cabinet。
