Technical Parameters：
What are the basic principles of GIS operation ？
Under normal circumstances, the circuit breaker and disconnector of GIS equipment are mainly operated remotely, and the "remote/local" opening of the circuit breaker and disconnector is concerned about the "remote" position.
The grounding switch of GIS equipment can only be operated on the spot, and the knife will be opened "remote/local" and concerned about the "local" during operation.
In any case, only the program can be operated, and the "interlock release switch" on the control cabinet must be in the "interlocking" position, and the unlocking key is sealed together with the microcomputer anti-mistaken unlocking key, and is used according to the same regulations.
