爆炸性环境中电气设计的要点分析

Key Points Analysis of Electrical Design in Explosive Atmosphere

根据GB 50058—2014《爆炸危险区域电力装置设计规范》及相关规范,从工程设计角度论述了爆炸区域的划分、爆炸性环境防爆电气设备的正确选型和防雷防接地等相关内容。提出爆炸性环境中电气设计人员应经济、合理地选用防爆电气设备,做好防雷接地设计工作,并辅以建筑物的防爆设计、加强通风等措施,以防止爆炸条件的形成及减轻爆炸危险的严重程度。

Accordign to GB 50058--2014 and relevant regulations, from the perspective of engineering design,this paper discussed the explosive area division,the proper selection of explosion-proof electric： equipments and the lightning protection grounding in explosive atmosphere. It is pointed out that the electrical designers should select the economic and reasonable explosion-proof electric equipments in explosive atmosphere, and conduct the lightning protection grounding design. The explosion-proof design, strengthening ventilation and other measures are adopted in building, in order to prevent the formation of explosive conditions and reduce the severity of explosion hazard.
