The effect of acid rain on the tracking resistance of organic insulating materials was studied by the IEC Publication 587 method in this paper. PP,PC,ABS,PS and PVC are evaluated each other after soaked in the solution of artificial acid rain for 20 and 45 days. Time to failure and the contact angle of the samples are investigated. The micro structure of sample surface is observed by SEM.And the tracking process is monitored by thermal video system. Test results show that the longer soaked period in the solution of artificial acid rain, the shorter time to failure and the smaller the contact angle of the samples. The mechanism of the effect of acid rain on the tracking resistance of materials is discussed furthermore. It's suggested that the acid rain can result in severe erosion damages which is mainly caused by the increasing of wetting and the decreasing of thermal resistance of test samples after soaked in acid rain solution.

采用IEC Publication 587方法研究了酸雨对有机绝缘材料耐漏电起痕性能的影响。对PP、PC、ABS、PS和PVC等材料在人工酸雨溶液中浸泡20天和45天后进行了评价。研究了样品的失效时间和接触角。利用扫描电镜观察了试样表面的微观结构，并利用热成像系统对跟踪过程进行了监控。试验结果表明，在人工酸雨溶液中浸泡时间越长，试样的接触角越小，达到破坏的时间越短。并对酸雨影响材料抗电痕性的机理进行了探讨。结果表明，酸雨对混凝土的侵蚀破坏是严重的，其主要原因是试样在酸雨溶液中浸泡后润湿性增加，热阻降低。
