摘要
GIS母线故障在大部分情况下是外观无异常,无异常气味,无气体泄漏的声音,看不到明显的故障点。针对无明显故障点的GIS母线故障,提出了一种GIS母线故障综合分析法,通过气室压力分析法、零序电流分析法、红外测温分析法及六氟化硫(SF6)气体组分分析法来综合判断故障部位。此方法在快速大致定位故障气室的前提下,有针对性地进行组分分析,可快速、可靠定位故障点,从而进行故障气室的隔离,恢复母线的运行,实际案例分析验证了该方法的有效性。
In most cases,there is no abnormal appearance,no abnormal smell,no sound of gas leakage,and no obvious failure point can be seen in GIS bus fault.Aiming at GIS bus faults without obvious fault points,a comprehensive analysis method for GIS bus faults is proposed.The fault is comprehensively judged by gas chamber pressure analysis method,zero sequence current analysis method,infrared temperature measurement analysis method and SF6 gas component analysis method Location.This method is based on the premise of quickly and roughly locating the faulty gas chamber,and conducts targeted component analysis to quickly and reliably locate the fault point,thereby isolating the faulty gas chamber and restoring the operation of the bus.The actual case analysis verifies the effectiveness of the method.
