    摘 要:风沙对复合绝缘子性能的影响是一个值得关注的问题。通过对风沙影响因素的分析并结合复合绝缘子伞裙硅橡胶材料的风沙试验,系统研究了风沙对硅橡胶材料力学性能和憎水性能的影响。研究结果表明:风沙对硅橡胶有一定的磨蚀作用,会导致硅橡胶厚度略有减小,力学性能有轻微下降;风沙会导致硅橡胶伞裙的憎水性暂时下降,但是硅橡胶具有憎水迁移性能,会使伞裙表面的憎水性在短时间内重新达到较高的水平,从而减小了绝缘子污闪风险。

    Abstract: The influence of wind sand on the performance of composite insulators is a noteworthy problem. After analyzing the influence factors of wind sand, and combining with the sand and dust test of silicone rubber used for composite insulator umbrella skirt, this paper carried out the systematic study on the influence of wind sand on the mechanical properties and hydrophobicity of silicone rubber. The experimental results show that the wind sand has the abrasive effect on silicone rubber, to result in a slight decrease in the thickness and mechanical properties. The wind sand may cause the hydrophobicity of silicone rubber temporarily decrease, however, the hydrophobicity of umbrella skirt surface can recover to a high level because of the hydrophobicity migration of silicone rubber, which reduces the risk of pollutionflashover.
    Key words: wind sand; composite insulator; mechanical property; hydrophobicity
