摘要
氧化锌避雷器在长期运行中,内部电阻片特性和绝缘状况会发生变化,导致泄漏电流超标,严重威胁着电网设备的安全稳定运行。通过分析本公司近年来氧化锌避雷器交流泄漏电流数据,结合红外测温手段,同时对设备进行解体分析,找出了氧化锌避雷器泄露电流超标的原因并进行分析和处理。
In the long-term operation of zinc oxide arrester,the characteristics of internal resistance sheet and insulation condition will change ,result in excessive leakage current and serious threat to the safe and stable operation of power grid equipment.Through the analysis of the data of current leakage of zinc oxide arrester of our company in recent years, combined with the infrared temperature measurement method,the cause of the leakage current of zinc oxide arrester is andlyzed and resolved.
