800M Valve Interlock Mechanism with Indoor High Voltage Switcgear KYN28-12
1. The interlock of high voltage switchgear is an important measure to ensure the safe operation of power network, ensure the safety of equipment and person and prevent misoperation. This is also clearly stipulated in GB3906, 3-35kV AC Metal Closed Switch Equipment.
2. Generally describe the interlock as: prevent misdivision, Misfit circuit breaker: prevent load separation, close isolation switch; Prevent the connection line(ground switch): prevent the connection line(switch) closed circuit breaker, load switch: prevent the accidental electrical interval.
3. The content of the above five items to prevent electrical misoperation is referred to as "five precautions". "Five-guard" devices can be generally divided into three categories: mechanical, electrical and integrated. At present, there are many types of high voltage switchgear in the market, most of which have a more perfect interlock mode. However, there are still a lot of high voltage switchgear interlocks, especially mechanical interlocks are not perfect, can not fully meet the "five defense" requirements.
4. For this reason, this paper deals with the KYN28-12 type metal closed armored removable switching equipment which is widely used in power system.
