摘要:
在设备预防性试验中,皂河站发现1#主电机A相其中一只线圈绝缘被异物损伤,详细论述了3种方案,包括更换损伤的线圈、现场绝缘修复、“丢线圈”法,经过方案比较,决定采用“丢线圈”方法进行处理,处理后试验合格,经过试运行和正常运行检验各项数据满足使用要求。
Abstract:
In the equipment preventive test, It is found that the insulation of one coil in phase A of the 1# main motor in Zaohe Station was damaged by foreign objects. Three schemes were discussed in detail, including replacing the damaged coil, on-site insulation repair and losing coil method. After comparing the schemes, it was decided to adopt losing coil method for treatment, and the test was qualified after treatment. After trial operation and normal operation inspection, all data meet the use requirements.
