乏燃料水池冷却泵电机综合故障分析

Comprehensive Defect Analysis of Cooling Pump Motor for Spent Fuel Pool

某核电厂目前使用的乏燃料水池冷却泵电机出现多次轴承磨损、卡涩、保持架断裂等故障缺陷,防城港、阳江等核电厂也出现过电机跳闸情况。电机解体后经过综合分析,找出了引发电机故障的原因,并经反复论证提出解决方案。

A nuclear power plant′s current spent fuel pool cooling pump motor has suffered multiple failures such as bearing wear,jamming,and cage fracture.Nuclear power plants such as Fangchenggang and Yangjiang have also experienced motor trips.After the disintegration of the motor,through comprehensive analysis,the cause of the motor failure was found,and the solution was proposed after repeated demonstrations.
