The schematic diagram of the control and protection action principle of 10KV high-voltage switchgear is worth collecting and learning!

10KV switchgear is a type of distribution switchgear equipment. The 10KV switchgear mainly includes isolation switches, circuit breakers, measurement and control protection devices, as well as electric operating mechanisms for circuit breaker operation and protection. The isolation switch includes one set of incoming and outgoing isolation switches, and one set of grounding isolation switches. The function of the incoming and outgoing isolation switches is to have a clear disconnection point with other electrical connection parts during the shutdown or maintenance of the 10KV switchgear to ensure safety.

Grounding isolation switch is used as a safety measure for maintenance of 10KV power lines. Circuit breakers are used for stopping and transmitting power on 10KV lines, and currently 10KV vacuum circuit breakers are generally used. The circuit breaker includes an electric operating mechanism, which is the mechanism for opening and closing the circuit breaker.

In the substations of power supply enterprises, microcomputer based comprehensive relay protection devices and related instruments are generally used to measure, control, and relay protect the operation of 10KV switchgear. The microcomputer based comprehensive relay protection device can support the "four remote" measurement and control of 10KV switchgear.
