安全壳空气冷却机组电机故障分析

摘要

恰希玛核电站二期（C2项目）安全壳空气冷却机组，在项目调试阶段的连续烧毁，暴露出该机组风机存在的问题是共性的。在此基础上，分析风机存在问题的原因，为后续及同类产品提供借鉴和参考。%The motor was continuously burnout in reactor containment vent cooling conditioner of C2 project, which indicated that there were general problem in the fan. This thesis analyses the problem of the fan in order to give advice and reference for similar product manufacture.
