接触网验电死区试验及分析田伟,白祥坤,邸晓新,赵国强(中国铁路北京局集团有限公司,北京100860)摘要:接触网设备间的同相电场干扰,使用容性验电器验电时存在无法正确指示设备带电的误报情况,直接影响作业人身安全。为研究接触网设备易发生验电死区位置,避免无效验电,对接触网各个位置进行了大量带电验电试验。通过对试验结果的对比分析,提出接触网验电位置选择建议和提高验电有效性的措施。关键词:验电试验;验电死区;验电位置中图分类号:TM732DOI:10.19768/j.cnki.dgjs.2023.04.030TestandAnalysisofCatenaryDeadZoneinElectricalInspectionTIANWei,BAIXiangkun,DIXiaoxin,ZHAOGuoqiang(ChinaRailwayBeijingBureauGroupCo.,Ltd.,Beijing100860,China)Abstract:Duetotheinterferenceofin-phaseelectricfieldbetweencatenaryequipment,thereisafalsealarmthattheca-pacitiveelectroscopecannotcorrectlyindicatethattheequipmentislivewhenitisusedforelectricityinspection,whichdi-rectlyaffectsthepersonalsafetyofoperation.Inordertostudythelocationwherethecatenaryequipmentispronetothedeadzoneofelectricityverificationandavoidinvalidelectricityverification,alargenumberofliveelectricityverificationtestshavebeencarriedoutatvariouslocationsofthecatenary.Throughthecomparativeanalysisofthetestresults,sug-gestionsontheselectionofcatenaryelectricityverific...
