摘要
内蒙古某发电有限责任公司2号机组正值C级检修中,利用Ca开关启动C给水泵进行空负荷试转时,C给水泵Ca开关故障,导致本侧负荷段全部失电。处理给水泵开关过程中发现负荷段失电的原因为负荷段设备线路安装布局不合理。对此提出负荷段改造,改造后保证了负荷段各项负荷的运行安全,同时做好日常巡回检查制度、负荷及负荷段事故跳闸的反事故演习等措施,确保了负荷段负荷开关稳定运行,保证了机组安全运行。
During the process of level C maintenance in unit 2 in Inner Mongolia Jinglong Electric Power Generation Co.,Ltd., in the test of starting feed water tmmp C with Ca switches, the Ca switch of feed water pump C failure, leading to all power Iossing in the side. Aiming at the fault reason analysis, based on the feed water pump switch trouble shooting raised the load segment for the cause of power losing was that the load segment installation layout was not reasonable. Put forward to make reform to the load segments, through which the safe operation of the load segment was ensured. Via the measurement of supervising the daily inspection, making anti-accident exercises of the load segments, to ensure the stable operation of the load switch of the load segments, the safe operation of the unit.
