本文通过对一起翻车砸断电缆而发电机未成功解网直至跳机的事故分析,对发电机低压低频保护的重要性进行说明,为余热值班人员分析处理问题提供参考。1事故经过矿山发生汽车翻车事件,车体全部砸向电缆桥架,车体压在主电缆上,开始时由于矿山出线主电缆被轻度砸伤,对地发生单相绝缘击穿。由于设备不能显示哪一支分路有问题,总降值班员判断不准确,未
In this paper, we analyze the accident of smashing the cable together with the generator failing to unload the network until the trip happens, and explain the importance of low-voltage and low-frequency protection of the generator to provide a reference for the analysis and treatment of the waste heat on duty.
