Abstract:

憎水性是衡量复合绝缘子运行性能的重要指标,研究憎水性分布规律有助于对测试结果进行更准确的评价。为此,以4支实际运行后的直流复合绝缘子为研究对象,分别采用喷水分级法和静态接触角法,进行了自然污秽下和去除污秽后的憎水性测试以及人工涂污后的憎水迁移性测试。研究结果表明,绝缘子高压端和低压端的憎水性整体差于中部,沿串表现出倒U形的憎水性分布,同时憎水迁移性较沿位置褪色较为严重,相比于褪色较轻的伞裙根部,其去除自然污秽后的憎水性较好,但是人工涂污下憎水迁移性明显较差。在各种憎水性试验中选择适合的测试方法,根据以上憎水性分布规律合理选取憎水性测试位置,所得试验结果能更好表征复合绝缘子运行性能。
