摘　　要：输电线路覆冰闪络故障严重影响电力系统安全运行,常规复合绝缘子在严重覆冰地区电气性能下降显著,较难满足严重覆冰地区的电气性能要求。鉴于此,国内外开展了诸如优化伞型、发热型和吸热型等多种防冰型复合绝缘子的研究,取得了较好的效果。然而,这些绝缘子往往存在提高了某些性能,但降低了另外一些性能的问题。因此,为了便于工程实际应用,有必要对新型复合绝缘子的性能评估方法进行研究。提出了防冰型复合绝缘子的性能评估方法,针对其特定性能,提出了安全性能评估和防冰性能评估两种子方法。通过对普通型绝缘子的测试试验,其结果可为评估方法中的比较参数提供参考,为防冰型复合绝缘子的设计和应用提供指导。The icing flashover fault of transmission lines seriously affects the operation of power system safely, and the electrical performance of conventional composite insulators declines significantly in severe icing areas, making it difficult to meet the electrical performance requirements in severe icing areas. In view of this, a variety of antiice composite insulators such as optimized umbrella type, heating type and heat absorption type have been studied at home and abroad, and good results have been achieved. However, these insulators often have the problem of improving some properties but reducing other properties. Therefore, in order to facilitate the practical engineering application, it is necessary to study the performance evaluation method of new composite insulators. A performance evaluation method for anti-ice composite insulators is proposed, and two sub-methods, safety performance evaluation and ice-proof performance evaluation, are proposed for its specific performance. The test results of ordinary type insulators can provide reference for the comparison parameters in the evaluation method, and provide guidance for the design and application of anti-ice type composite insulators.
