摘要
Abstract
Unit 2 in some power plant was forced to shutdown, because the air source of slight pressure device was too moist, the water removal capacity of air compressors was decling, environmental temperature was quite different, the enclosed busbar had leakage, some faults existed in parts of busbar′s structure of branch circuit TA, which caused the dewing and hydrops in isolated phase busbar in TA section, and further caused the discharge and shutdown. The measures of replacing the air source of air compressor, equipped with gas heating device, and transforming the isolated phase busbar TA section of HV auxiliary transformer high voltage side, eliminated the dewing and hydrops, which ensured the safe and stable operation of the unit.关键词
