摘　　要：针对佛山局某一批次10 k V避雷器频繁出现异常情况,利用高频脉冲电流极性定位法展开对该类型避雷器的故障检测及缺陷定位的研究,并通过EMTP/ATP仿真、现场验证、解体分析,验证了该方法的有效性和可行性,找到了该类型避雷器频繁出现问题的原因,为避雷器工艺质量的提高提供了相应的技术支持,具有一定的工程实践意义。Aiming to the abnormal conditions occurred frequently in Foshan to a batch of 10kV arresters,using high frequency pulse current polarity orientation method,the fault detection and the location of defects of this type arrester are studied. The validity and the feasibility are verified by the EMTP/ATP simulation,field test and disintegration analysis. The cause of the problems frequently appearing in the arrester is found,which can provide the corresponding technical support for the quality improvement of surge an＇ester technology and has certain practical significance.
