静电灾害是在一定条件下造成的,静电作为火源引起爆炸和燃烧的条件可归纳为4点,即:①有静电产生的来源;②静电得以积聚,并达到足以引起火花放电的静电电压;③静电放电周围存在爆炸性混合物;④静电放电的火花能量达到爆炸性混合物的最小引燃能量。
Electrostatic disaster is caused under certain conditions, static electricity as a source of ignition caused by explosion and combustion conditions can be summarized as 4, namely: ① have a source of static electricity; ② static electricity can be accumulated and reach enough to cause spark discharge electrostatic voltage; ③ there is explosive mixture around the electrostatic discharge; ④ spark discharge energy reaches the minimum ignition energy explosive mixture.
