    摘 要:針對(duì)某 110 kV 輸變電工程 10 kV 開(kāi)關(guān)柜調(diào)試過(guò)程中,出現(xiàn)“斷路器合分一次后,無(wú)法進(jìn)一步電氣操作,但手動(dòng)合分正常,此時(shí)重新將斷路器控制回路斷電,又能再次操作斷路器,但仍只能合分一次,無(wú)法再次電氣操作”的問(wèn)題,對(duì)斷路器內(nèi)部防跳回路、合閘回路、跳位監(jiān)視回路及微機(jī)保護(hù)接線回路進(jìn)行分析,并根據(jù)實(shí)際的現(xiàn)場(chǎng)調(diào)試情況或者運(yùn)行工況,制定出最符合現(xiàn)場(chǎng)情況的解決方案,為后續(xù)現(xiàn)場(chǎng)調(diào)試或?qū)嶋H運(yùn)行時(shí)出現(xiàn)同類問(wèn)題提供了參考。

    Abstract: In a 110 kV power transmission and transformation project, a problem exists in the progress of the 10 kV switchgear debugging.The problem is that after the first movement of the circuit breaker, it can only operate by hand movement. In this situation, if the operator cuts the electricity of the circuit breaker control loop, the circuit breaker will run again, but it will still be a one-time operation.Given this problem, this article analyzed the internal anti-trip circuit, closing circuit, trip monitoring circuit, and microcomputer protection wiring circuit of the circuit breaker. It makes an appropriate solution for the on-set situation and provides a reference for similar problems.
    Key words: circuit breaker; anti-trip; trip monitoring; self-hold; relay reset
