摘要: 根据静电隐患的分析理论和某货场的实测数据,对铁路危险品货场中的静电隐患进行了直接评估与机理分析,并提出了流动人体模型和人体一手推车模型.实测数据、直接评估、机理和模型分析表明,铁路危险品货场中存在着严重的静电隐患:(1)人体静电电击明显存在;(2)既存在易燃易爆货物,又存在多种静电源,且静电放电能量大于许多易燃货物的最小点火能量,静电放电引燃引爆的隐患难以排除.因此,铁路危险品货场中静电隐患的防护必须受到重视.文中最后提出了具有切实参考作用的预防措施.

Abstract:

Acc0rding to the analytical theory of electrostatic hidden troubles and the practical data gathered in a Railwav Freight Yard for dangerous goods,the electrostatic hidden hazards in the railway freight yard fo r dangerous goods were directly evaluated and analyzed,and two models,namely,the Floating Human Body Model and the Hu-man Body-BaITow Model,ere put forward.Some feasible preventive measures were finally presented in the paper·
The Dractical data,the resuIts of direct evaluation,mechanism analysis and model analysis all show that there exist serious electrostatic hidden hazards in the railway freight yard for dangerous goods because there lS an obvious state of electrostatic shock to the human body,and there are not only lots of easy-burning or easy-blasting goods but also manv kinds of electrostatic sources in the railway freight yard.The electrostatic discharge energy exceeds the mini-mum igniting energy of most easy-burning goods,thus resulting in the dificulty in the removal of hidden hazards of
buming and blasting caused by electrostatic discharge.Therefore,more attention should be paid to the protection of electrostatic discharge in the railway freight yard for dangerous goods.

Key words: railway freight yard for dangerous goods, electrostatic hidden trouble, measurement, evaluation, mechanism analysis, model analysis, preventive measure
