Abstract: In allusion to the problems that in secondary design of switchgear, the skip monitoring circuit has non overall integrity of monitoring circuit breaker closing circuit and the draught fan control circuit of large current switchgear couldn’t realize intelligent control, this paper analyzed the design methods of secondary circuit. After coordinating test of comprehensive protector and relay, this paper proposed the optimization scheme of secondary circuit design, which raises the reliability and intelligence of switchgear operation.
Key words: medium voltage switchgear; closing circuit; skip monitoring; draught fan control circuit; secondary optimization design
