摘要
国家规范明确规定了需要防爆设计的情况,防爆电气设备选型应综合考虑爆炸危险区域划分和介质的危险性,多组分爆炸性气体混合物可通过计算确定其级别。
Explosive proof design is clarified in standards definitely.Hazardous zone classification and explosive risk degree should be both considered in electrical equipment selection.The grade of explosive multi-component gas can be quantitative calculated.
