摘要
进行继电保护校验工作时,二次措施的执行和恢复往往需要占用较多的时间。尤其是电压试验线的装拆,受端子排格局的限制,出现误碰、接触不良等风险,导致校验时间增加,校验结果出错一系列问题。因此,分析了在校验过程中,电压试验线接入的几种方式,提出了一种新型电压试验线接头,并进行了性能测试,探讨了其应用情况,提高了校验效率。
When carrying on the relay protection check work,the second measure execution and the restoration often need to occupy many time,especially the voltage test line's assembling and disassembling,is restricted by the terminal row pattern,appears the wrong contact and so on risk,causes the check time to increase,the check result wrong series of questions.This paper analyzes several ways of voltage test line connection in the process of calibration,puts forward a new type of voltage test line connection,and tests its performance,discusses its application and improves the calibration efficiency.
