Analysis Of Scenarios Where Power Is Connected To The Sides Of The Moving And Stationary Contacts Of A High-voltage Disconnector.

The installation layout of High Voltage Disconnect Switch is not static. In common designs, the stationary contact is usually connected to the power supply side, while the moving contact is connected to the load line. This configuration conforms to the traditional disconnector circuit structure. However, in some installation scenarios within power receiving cabinets, different wiring methods may be used due to specific space and wiring requirements.

This wiring method is related to the utilization of cabinet space and the convenience of wiring. Inside the power receiving cabinet, the cable entry point is usually from one side of the cabinet, closer to the side contacts of the disconnector switch. Connecting the power supply end to the side contacts reduces cable bends, improves wiring compactness, and facilitates maintenance operations.
