接地防静电火灾的效力与辅助措施

Efficiency of Grounding on Anti-static Fire Hazard and Auxiliary Measures

针对近年来因在接地防静电中忽视辅助措施,发生多起静电火灾的问题,分析了接地防静电的效力和接地后仍可能引发静电火灾的原因:管输液流与管道内壁、管口之间形成电位,发生火花放电。基于此提出了常用接地防静电的必要辅助措施。

Due to the auxiliary measures in grounding being neglected,static fire hazards occur in recent years.Aiming at the issue,efficiency of grounding of anti-static fire hazard and reasons of static fire still occurred after grounding are analyzed.Results display that this type of fire hazard is mainly induced by spark discharge from potentials formed between transported liquid and pipe inner wall and pipe orifices.Necessary auxiliary measures for grounding of anti-static fire hazard are presented.
