摘　　要：研究避雷器电阻片固有的热特性,测量避雷器在正常运行电压下的温度分布情况。对于正常及劣化避雷器、无间隙和有间隙避雷器进行各种对比试验,分别测量其温度变化情况。研究避雷器电阻片发生受潮或老化等情况对避雷器温度分布的影响,为通过使用温度判据进行避雷器故障诊断提供了真实数据,同时也为避雷器的状态评价提供有力支持。The inherent thermal characteristics of the arrester varistors is studied, the temperature distribution of arrester at normal operating voltages is measured. For the normal and deterioration arrester, without gap and gap attester, various comparison test are carried out, the temperature changes are measured respectively. Research the influence of the condition that the varistors occurring damp or electrical aging on the temperature distribution of surge arrester, real data is provided for lightning arrester fault diagnosis by using the temperature criterion, and also strong support is offered for the state evaluation of arrester.
