危险区域分级和危险区域电工设备的选用

Classification of hazardous area and electric equipment used in the area

危险区域电工设备由于使用条件比一般条件更为苛刻 ,因而在设计中应考虑更多的因素。对危险区域的分级、设备的要求及评价作了分析和对比 ,以供设计危险区域的电工设备时参考。

The working environment for electric equipment in hazardous area is severe. Therefore more factors should be taken into account in design. The classification of hazardous area, requirement and assessment for the equipment in the area are analyzed and compared in this paper which aims at giving reference to designing the electric equipment used in hazardous area.
