摘要
Abstract
In routine direct current test of zinc oxide arrester, it is necessary to disconnect the high voltage lead from the pri-mary winding. Due to the large height of the 3-laminative structure and the heavy lead weight of the 500 kV zinc oxide arrester, it is labor and time consuming to disconnect the high voltage lead in maintenance, which also increases safety risk and mainte-nance costs. Taking a hydropower station as an example, the direct current test methods of the 500 kV zinc oxide arrester with and without disconnecting the leads are introduced. The comparison and analysis of the test figures of the two methods reveal that the method without disconnecting the lead is able to meet the requirements of test specifications.关键词
