1992年5月,某木材加工厂用汽油洗刷油罐时突然发生爆燃。我们对送检的灯头、灯头尾线、插座、家用吹风机进行检验,发现火烧、烟熏造成的熔化、烧焦、油质物及灯头尾线的黄色塑料绝缘皮的严重变形、破裂、焦糊、炭化、导线抻拉等现象,未见电源材料短路打火引起爆燃的痕迹特征及内热现象。但对送检的从罐口引入到罐内的电源导线进行检验时发现在进入罐内的两根电源导线的端部,有短路打火痕迹。分别截取该电线引线的两头,一根为3.5厘米,一根为5.0厘米,两根导线的黄色塑料绝缘皮表面及内
May 1992, a wood processing plant with a sudden burst of gasoline scrub tank. We inspect the lamp cap, lamp tail, socket, home hair dryer for testing and found that fire, smoke caused by melting, burning, oil and light the tail of the yellow plastic insulation skin serious deformation, cracking, scorching , Carbonization, wire 抻 pull and other phenomena, no power material short circuit ignition caused by traces of the characteristics of the deflagration and the internal heat phenomenon. However, the inspection of the power supply wires introduced into the tank from the tank mouth revealed short-circuiting marks at the ends of the two power supply wires entering the tank. Respectively intercepting the two ends of the wire lead, one for 3.5 cm, one for 5.0 cm, the two yellow plastic wire insulation surface and the inner
