广东电网污秽地区耐张串试用复合绝缘子运行情况分析

Operation Condition Analysis of Tension Strands Consisting of Composite Insulators on Probation for Polluted Region in Guangdong Power Grid

广东省500 kV惠汕甲线60支耐张串试用国产复合绝缘子已运行4年,2006年对其中4支耐张串复合绝缘子进行了抽检试验,文章对试验结果进行了分析,总结了广东电网复合绝缘子应用于耐张串的运行经验,讨论了耐张串复合绝缘子的运行维护问题,证明了污秽地区耐张串试用复合绝缘子的可行性。

60 pieces of tension strands consisting of domestic composite insulators has been put into operation on 500 kV Hui-Shan Jia Line in Guangdong for four years. In the year of 2006 the sample survey on four composite insulators among these 60 pieces of tension strands is carried out. The authors analyze the test results, summarize the operation condition of composite insulators applied to tension strands in Guangdong power grid, research the operation and maintenance of composite insulators used for tension strands, and prove that in polluted region the probation of composite insulators for tension strands is feasible.
