摘　　要：针对新建的吉林市城西变电所一个半断路器接线型式,结合运行经验对原有远方跳闸保护微波通道的切换方式进行全面改造,实现"二取二"运行方式及满足旁路保护转带需要,不仅简化了二次回路接线,也彻底解决了松西甲、乙线在音频保护通道出现异常造成启动装置被迫停用进而引起吉林城网重大设备隐患的问题。试验证明,所采取的技术方案及更改措施是正确的。In consideration of the connection mode of one and a half circuit breaker of the west transformer substation of Jilin City, combined with the operation experiences, the switching modes of the microwave channel of remote protection are improved for the realization of the ＂double in double＂ mode and satisfaction of the need of bypass protection. Not only is the secondary circuit predigested, but also the faults of forced break of start equipment caused by the abnormity of the audio frequency protection channel of Songxi line, which will lead to serious hidden trouble of the Jilin City Power Grid, are solved. Experiment proves that the technique adopted and the measures taken are effective.
