±800kV特高压直流避雷器的均流特性试验
Current Sharing Performance Tests of Arresters Used in ±800 kV DC Transmission System
摘要
Abstract
Through the tests of 4-column parallel arrestor assembly, the impacting factors on the uneven current distribution in arrestors used in ±800kV DC power transmission system are analyzed. Test results show that to achieve the aim of current sharing the deviation of voltage reference UDC1mA for DC 1 mA should be as small as possible and the non-uniform coefficient should be determined by switching impulse current sharing test or lightning impulse current sharing test. Along with the increasing of impulse current, the non-uniform coefficient decreases gradually.关键词
