Abstract
ZCW-363 type outdoor HV isolation switch is widely used in power grid, but this type of isolation switch adopts AC-DC mixed control circuit which exists hidden trouble of misoperation in application of Yinchuan Eastern 750 kV Converter Station. Aiming at this problem, by analysis the control circuit, puts forward the improvement measures of installing electrical relay in control circuit. The practical effect shows that improvement realizes absolute isolation between AC circuit and DC cir-cuit, the isolation switch operates well after the control circuit optimized, ensures HV power grid reli-able and safe operation.关键词
