摘要
针对电力系统近年来大面积污闪事故的新动向 ,研究了大气环境的酸性湿沉降对绝缘子交流闪络机理、闪络特性的影响。通过试验 ,得到了绝缘子的交流闪络电压与湿沉降的值及电导率的关系 ,并探讨了酸性湿沉降环境下绝缘子闪络特性的表征量。
The paper regards to the problem of widespread pollution flashover happened in power system in the recent year, and studies the AC flashover mechanism and flashover performance of insulators in the acid environment. Through a large of tests, the relation between the AC pollution FOV(flashover voltage) of insulator and the pH as well as conductivity of the wet precipitation is found, the token of flashover performance of insulators in the wet depositions is discussed.
