What is the purpose of HV switchgear?

The main function of the high and low voltage switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and electrical energy conversion in the power system. Generally, it has a simple and reliable "five protection" interlocking function to prevent misoperation. The appearance is novel, flat, concise, uniform in color, and thick and heavy. The secondary trunking in the high-voltage room adopts all-metal protection, which makes the operation safer and more reliable. , It has the characteristics of a more humane man-machine interface and explosion-proof operation.

Five protections

1.Prevent misoperation of the circuit breaker;

2.Prevent the disconnect switch from being pulled on with load, that is, to prevent pushing and pulling the trolley with load;

3. Prevent the grounding wire from being connected to the ground when the power is on, that is, prevent the grounding switch when the power is on;

4.Prevent power transmission with grounding wire, that is, prevent power transmission when the grounding switch is in the grounding position;

5. Prevent entering the electrified interval by mistake
