摘要
通过化学和电气试验等手段,对胪岗变电站500 kV胪祯甲线并联电抗器投产后油中色谱烃类含量异常现象进行研究,在此基础上对故障设备进行吊罩内检,查明A相高抗的悬浮放电故障是接地螺栓松动所致,经处理后色谱数据恢复正常.同时指出了油中溶解气体色谱分析可以及时发现设备内部故障,是充油电力设备故障判断的重要方法.
By means of chemical and electrical test,the over-standard hydrocarbons in oil GC has been researched after 500 kV Luzhen Jia shunt reactors in Lugang substation put into operation.Furthermore,the overhaul of equipment was carried out to ascertain the reason of suspended discharge.The failure of suspended discharge is due to ground bolts loose.After treatment,chromatography data return to normal.Thus,it can come to a conclusion that oil GC analysis is an important method to determine the fault of oil charged power equipment.
