摘要
对某核电厂非安全级电动机低电压保护方案进行了总结,对电动机低电压保护整定时间进行了分析,综合电动机不同的功能、电源瞬态切换中电压与时间关系,提出按电动机功能分别设置整定时间的优化建议方案.结果可供工程设计借鉴.
Abstract
The low voltage protection scheme of non-safety motor in a nuclear power pant is summarized,and the setting time of motor low voltage protection is analyzed.Based on the different functions of motor and the relationship between voltage and time in transient power supplyswitching,the optimization Scheme of setting time according to motor function is proposed.The resluts can be used as reference for engineering design.
