摘要: 为研究复合绝缘子表面憎水性与环境因素的关系,采用喷雾试验和浸泡试验模拟了不同工况下的绝缘子老化过程,采用动态接触角测量法分析了腐蚀时间及不同酸碱腐蚀条件下绝缘子试样表面的憎水性,并采用扫描电镜分析其表面形貌。试验结果表明,复合绝缘子在长期的污湿环境下,其表面的憎水性逐渐减弱,甚至有可能完全丧失。酸性环境对绝缘子表面憎水性影响较中性、碱性环境影响大。绝缘子表面受到酸性物质的腐蚀影响比中性、碱性物质腐蚀影响大。

Abstract: In order to study the relationship between environmental factors and composite insulator surface hydrophobic characteristic, composite insulator aging process in different conditions is simulated by spray test and immersion test. The surface hydrophobic nature is analyzed by using dynamic contact angle method under different spray time and acid corrosion conditions. Surface morphology of the samples are analyzed in detail by scanning electron microscopy(SEM). The experimental results show that the surface hydrophobic gradually weaken, and may even be completely lost by long exposure to dirty wet environment. Acidic environment have much greater impact on the surface hydrophobic than neutral or alkaline environment because acidic substances have greater influence on the surface compare to neutral or alkaline substances.

Key words: composite insulator, hydrophobic nature, spray time, acid corrosion, surface morphology
