中压核级电动机空水冷却器分析与探讨

Analysis and Discussion on Material Selection of Medium-Voltage Nuclear-Grade Motor Air-Water Cooler

中压核级电机的空水冷却器通过外部水循环冷却电机,对电机的稳定运行具有重要的作用,特别是中压核级电机核安全功能、寿命等,相应的规范对空水冷却器的化学成分、力学性能、检验试验、使用寿命等方面有很高的要求,结合相应的规范、标准分析不锈钢316L可替代不锈钢Z2CN18-10应用于中压核级电机的空水冷却器。

It introduces air-water cooler in medium-voltage nuclear-grade motor: cools the motor through the external water circulation,it plays an important role in the stable operation of the motor,especially the nuclear safety function and service life;the corresponding specification indicated high requirements in chemical composition,mechanical properties,inspection test,service life,etc. This paper indicates that stainless steel 316 L can be used as an alternative to stainless steel Z2 CN18-10 for medium-pressure nuclear-grade motors combined with the corresponding specifications and standards.
