Five performance characteristics of high voltage switch cabinet

High-voltage switch cabinet can be used in power systems to cut off, control or protect in the process of power generation, transmission, distribution, transfer and consumption. Manufacturers of high-voltage switchgear can classify electrical products with voltages ranging from 3.6kV to 550kV into high-voltage isolating switches and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectioning devices, high-voltage operating mechanisms, high-voltage explosion-distribution devices, High-voltage switchgear, etc. Product performance has the following characteristics:

1. After the vacuum circuit breaker trolley in the high voltage switch cabinet is turned on in the test position, the circuit breaker of the trolley cannot enter the working position.

2. When the grounding switch in the high-voltage switch cabinet is closed, the circuit breaker of the trolley cannot enter the closed working position.

3. When the vacuum circuit breaker in the high-voltage switch cabinet is opened, the front and rear doors on the board should be locked to the cabinet door by the mechanical device on the grounding switch.

4. When the vacuum circuit breaker in the high voltage switch cabinet is opened during operation, the grounding switch cannot be closed and put into operation.

5. When the vacuum circuit breaker in the high voltage switch cabinet is opened, the circuit breaker of the trolley cannot exit the working position.
