摘　　要：针对电厂引风机高压电机在运行中发生的,由定子线圈绝缘损坏导致的故障跳闸,通过对故障部位的解体及分析,认为引风机高压电机以故障原因与电机增容改造后的铁心片间绝缘损坏以及绝缘裕度降低有关。结合实际检修情况,提出了厂用高压电机日常运行维护的注意事项,并制定了防范措施,以避免类似问题再次发生。The stator coil insulation of the high voltage motor used in a power plant is damaged during operation, resulting in fault trip. Through the disassembly of the fault part, the cause of the motor fault is analyzed, which is related to the reduction of the insulation margin and damage of stator core insulation after the motor capacity expansion rebuilding. Combined with the actual situation, the matters needing attention in the daily operation of the auxiliary motor are put forward and the preventive measures are formulated to avoid the recurrence of similar problems.
