摘要
合成绝缘子以其优良的性能在电力系统中得到了普遍认可和大量使用，但随着运行年限的增加，合成绝缘子暴露出的问题也越来越多。为了准确掌握运行达一定年限后的合成绝缘子的电气性能和机械性能，保证电网安全运行，有必要对合成绝缘子进行抽样试验。对湖南电网2006—2007年连续2年开展的运行中合成绝缘子抽检试验结果进行了综合分析，总结了湖南电网合成绝缘子的运行状况，为今后合成绝缘子的安全运行提供了指导性建议。
The composite insulators are widely used in power system due to their excellent performance. With the increase of operation years, composite insulators exposed many problems. In order to master the electric and mechanical properties of composite insulators after operating several years and ensure power network safety, it is necessary to carry out the random sampling test for the composite insulators. The random sampling test results of the composite insulators used in Hunan power grid from 2006 to 2007 were surveyed and the operation condition of composite insulators were summarized, offering the references for future safe operation of composite insulators.
