1988年7月27日,在济津公路铺路工地上,发生一起中性线触电死亡事故。铺路临时工地,设在乡镇排灌站。电网上有电时,由该站的变压器供电;电网停电后用自备电源。自备电源是排灌站配电房内安装的一台7.5kW发电机。带的负荷是水泵和照明。配电盘与发电机之间只有0.5m的小道。零线从发电机的接线柱沿着小道,通过小门接到相距100m的水泵照明灯上,悬挂高度只有1.2m,拴得不牢固。配电房建在河边上,土质含盐分。7月下旬,正是当地降雨季节,阴雨连绵,河水上涨,河水距离配电房的地面只有1m左右,房内很潮湿。中性线的绝缘已经老化,发生漏
July 27, 1988, paving the way in Ji-Jin Road, a neutral electric shock occurred. Paving temporary site, located in the township irrigation station. Power on the grid, the station by the transformer power supply; The self-provided power is a 7.5kW generator installed in the power distribution house of the irrigation and drainage station. The load on the belt is water pump and lighting. Only 0.5m between the switchboard and the generator. Zero line from the generator terminal along the trail through the small door to the water pump lights 100m away from each other, the suspension height of only 1.2m, poorly tied. Power distribution room built on the edge of the river, soil salt content. In late July, it is the local rainfall season, rainy, river rises, the water is only about 1m from the floor of the power distribution room, the room is very humid. Neutral insulation has been aging, leakage occurred
