摘　　要：为消除某500 kV并联电抗器内部间歇性放电故障,分析了该电抗器内部间歇性放电的特征,利用油中溶解气体含量、电气试验数据对故障性质和故障部位进行了判断。通过现场吊罩检查验证了判断的准确性,并针对发现的问题提出了处理措施。分析结果及提出的建议对并联电抗器色谱分析及故障判断有一定的借鉴意义。In order to eliminate the internal intermittent discharging fault in a 500 kV shunt reactor, characteristics of the internal intermittent discharging in the shunt reactor are analyzed. The property and location of the fault is judged by using the content of dissolved gas in oil and electrical test data.The hangingmantleinspection verified the correctness of the judgment. Treatment measures are proposed for the found problem. Analysis result and proposed suggestions have certain reference significances for the chromatographic analysis and the fault judgment of shunt reactor.
