摘要
Abstract
This paper mainly describes the electrical preventive tests conducted during the seasonal maintenance process of Lvshuihe Power Plant,focusing on the methods and characteristics of measuring DC leakage current and DC withstand voltage tests for electrical primary equipment such as generators,transformers,busbar cables,lightning arresters,and transformers.It checks whether there are any defects in the operation of the equipment after one test cycle through experimental methods.And according to the requirements of relevant regulations,it checks whether the electrical performance and related parameters of the equipment meet the requirements of the regulations,provides test basis for the safe and stable operation of primary equipment,and provides data support for equipment maintenance and repair.关键词
