摘　　要：地铁工程变电所35 kV开关柜室仅通过35 kV开关柜自身配置的密度继电器来实现SF_6气体密度的监测,存在很大的安全隐患,为保证35 kV开关柜的可靠运行,从而提高供电系统连续可靠运行能力,对SF_6气体实现在线状态监测与故障预测,已经成为地铁35 kV开关柜安全运行的重要因素,因此提出建议在新建地铁线路35 kV开关柜室配备SF_6气体监测装置,分析了SF_6气体监测装置的组成、功能以及应用实例。The subway engineering change substation 35 kV switchgear room were the 35 kV switch cabinet of the self configuration of the density relay to realize the monitoring of SF6 gas density,however density relay only in the switch cabinet has a lot of SF6 gas leakage to act,there is a big security risk,in order to ensure the reliable operation of 35 kV switch cabinets,improve the power supply system of continuous and reliable operation ability and the SF6 gas to achieve online state monitoring and fault prediction has become a subway 35 kV switch cabinets on the safe operation of the important factors,therefore puts forward the proposal prepared in the new subway lines 35 kV switch cabinet with SF6 gas monitoring device. The composition,function and application example of SF6 gas monitoring device are analyzed in this paper.
