摘要
针对神华河北国华沧东发电有限责任公司给煤机在其上口电气开关电源切换时发生跳闸事故,不能正常自启动的情况,通过对给煤机的控制回路进行改造,使给煤机在其电气开关允许的时间内切换完成后能够自启动。同时介绍了改造对给煤机转速和MFT回路的影响,指出改造应注意的事项。
In accordance to coal feeder tripping during switching over of above outlet electric switch, leading to be difficult to self-starting, the switch can self-starting after switching over in allowable time, through alteration for coal feeder control circuit. This paper also introduces the influence of refor marion to coal feeder rotate speed and MFTcircuit and at the same time,indicates the attentive thing for the reformation.
