阴雨连绵的日子里,进户线的配电盘下涌集了一滩水,那水珠不住地滴落着。经查看,房顶并无漏雨迹象。那么,这水是从哪儿来的呢?电工小李疑惑不解地去请教王技师。王技师仔细查看以后,用手指着进户线说:“你看,是进户线的橡皮芯在滴水。“线芯是多根裸线绞合而成的,绞合之间有间隙,雨水沿着裸线间隙流出。自动空气开关盒底已有积水。幸亏发现及时,没有造成短路事故。 During the rainy days, a water drained down the distribution board of the entrance line, and the water dripped. Upon inspection, there is no sign of leakage on the roof. Well, where did this water come from? Electrician Li was puzzled to consult Wang’s technician. After watching carefully, the Wang technician pointed his finger at the entrance line and said, “You see, the rubber core of the entry line is dripping.” The core is made up of multiple bare wires, with gaps between the strands, rainwater. Flow out along the gap between the bare lines. There is water accumulation at the bottom of the automatic air switch box. Thanks to the timely discovery, no short circuit accident was caused.
