马达保护器频繁跳闸原因分析及处理措施

Motor Protection Frequent Tripping Analysis and Treatment Measures

在工业实践中,电机会由于电性原因发生负荷、缺相、层间短路及线间短路,线圈的接地漏电,瞬间过电压等问题,使电机造成损坏,并且还会因为机械原因,如堵转、电机转动体遇到固体时,因轴承磨损或润滑油缺乏出现热传导现象,损坏电机。所以要做好对电机的保护措施,为其正常运转提供保障,避免频繁出现事故,将损失减小到最低。文章主要以北京京能未来燃气脱硝系统2#稀释排烟风机在运行过程中频繁停车事故为例,分析了2#稀释排烟风机频繁停车的原因,并经过对控制回路相关改进,消除了相关故障。

This paper mainly in Beijing Beijing to future gas denitration system # 2 diluted exhaust fan stop frequently during the run accident as an example, analyzes the No. 2 diluted exhaust fan frequent stop reasons, and through related improvements to the control loop, eliminating related fault.
