| 摘 要： | 为了分析10 kV配电线路避雷器的故障情况,以珠江三角洲某地区2010年10 kV配电线路避雷器故障数据为样本,分别从污闪和避雷器质量两方面对避雷器故障进行研究.通过对不同部位避雷器污染进行分析,结合对避雷器自身的电阻片特性和密封性能的研究,得出造成避雷器故障的原因主要是避雷器自身电阻片以及密封性能存在缺陷,少数受污严重的避雷器在潮湿环境中发生闪络.

| Abstract: | In order to analyze the fault condition of 10 kV distribution line surge arrester,taking the fault data of 10 kV distribution line surge arrester in an area of the Pearl River Delta in 2010 as an sample,the arrester faults are analyzed from the aspects of pollution flashover and arrester’ quality respectively.Through the analysis on the pollution flashover on different positions of arrester and combined with the research on the resistor characteristics and sealing property of arrester,the results indicate that the main reasons of arrester faults are the defects in the resistor and the sealing property of surge arrester and flashover occurred on a few severely polluted surge arresters in humidenvironment. |
