摘要
太原二电厂的200MW机组自投产以来，6kV厂用备用电源开关在备自投装置合闸后常常未见明显原因跳闸。该文从电机暂态分析入手，找出故障的原因和解决方法，供同类型或相似类型的机组在设计和改造时参考。
After the 200MW units in Taiyuan No. 2Power Plant were put into operation, the switch of 6kV emergency auxiliary power was opened without obvious reason at all times after it was closed by the emergency commission automaton. After analysing the transmitting behavior of motors, the reason of the accidents and the improvelnent measures are found.
