摘要
从3个方面即试验方法的合理性、等价性、实用性出发,讨论和分析了1000kV特高压交流系统用无间隙金属氧化物避雷器的线路放电试验方法。并以我国1000kV特高压交流线路实际参数和预期过电压标么值为参考,试定义了可以满足1000kV避雷器2次线路放电注入的能量>40MJ要求的第6级线路放电试验参数,规范了第6级线路放电的试验方法,可供我国1000kV避雷器标准制定时参考。
Starting from three aspects： the rationality of the test method, the equivalence of the test method, the practicality of the test method, the paper discusses and analyzes the line discharge test method on the MOA for 1000 kV UHV AC systems. Based on the practical line parameters and prospective calculated switching overvoltage of 1000 kV UHV AC systems, design the test parameters for the 6 class line discharge test on 1000 kV MOA , that can meet the energy requirements of not less than 40 MJ pre-injected into 1000 kV MOA during 2 times line discharge test. Make the specifieations about the 6 class line discharge test method, as a reference to draw up the standard for 1000 kV MOA in China.
