基于脉冲电压及超声检测的GIS母线故障定位技术研究
|
摘要
气体绝缘全封闭组合电器(gas insulated switchgear,GIS)长母线发生故障后尚无有效方法对故障点进行快速精准定位,为此提出利用脉冲电压及超声检测进行GIS母线故障定位方法。该方法首先通过高压脉冲激发故障点产生放电,并将多路超声传感器布置于故障GIS母线外壳检测放电信号,然后采用无线自组网技术同步采集多路传感器信号,最后通过幅值比较判断放电信号,从而确定故障点所在位置。将该方法应用于广州电网某变电站220 kV GIS 2号母线故障后的定位检测,检测结论与解体检验结果相吻合,从而验证了该方法的有效性和实用性。
In order to solve the problem of fast and accurate location of fault points after gas insulated switchgear(GIS) bus failure, this paper proposes to use pulse voltage and ultrasonic detection for GIS bus fault location. This method firstly makes use of high voltage pulse to stimulate the fault point to generate discharge and arranges multi-channel ultrasonic sensors along the GIS bus to detect discharge signals. Then by using wireless self-organized network technology, signals of multi-channel sensors are synchronously collected and discharge signals are decided according to amplitude comparison so as to determine location of the fault point. This method was used for location detection after 220 kV GIS No.2 bus failure in a substation of Guangzhou power grid. The detection conclusion is corresponding to disintegration inspection result, which verifies effectiveness and practicability of this method.
