摘　　要：本文介绍了真菌的相关特性,在实验室条件下培养真菌并移植到硅橡胶绝缘子表面,然后对受污染的硅橡胶材料进行静态接触角、盐密、灰密及污闪电压的测量,从而分析真菌对于硅橡胶绝缘子憎水性的抑制情况及对污闪电压的影响。结果表明:真菌附着在硅橡胶绝缘子的表面使绝缘子的憎水性能下降,真菌的浓度越大,憎水性越差;硅橡胶绝缘子表面的污闪电压也因真菌的附着稍有下降;同时,真菌浓度越大,相应的盐密和灰密越高。This article introduced the relevant characteristics of fungi.Fungi were cultivated under laboratory conditions and transplanted to the surface of silicone rubber insulators.Then,the static contact angle,ESDD,NSDD,and pollution flashover voltage of contaminated silicone rubber insulators were measured.The inhibition of fungi on the hydrophobicity of silicone rubber insulators and its influence on the pollution flashover voltage were analyzed.The results show that the adhesion of fungi on the surface of the silicone rubber insulator decreases the hydrophobicity of the insulator.The higher the concentration of fungus,the worse the hydrophobicity;the pollution flashover voltage on the surface of the silicone rubber insulator decreases slightly due to the adhesion of fungi;at the same time,the higher the concentration of fungi,the higher the ESDD and NSDD.
