厌氧罐区的电气设计

Electrical Design for the Area of Anaerobic Jar

厌氧罐产生含有主要成分为甲烷的沼气,甲烷为可燃性气体,厌氧罐区为爆炸性气体环境。该区域的电气设计主要包括爆炸危险区域划分、设备选择、配电、线路敷设、设备安装和防雷接地等,主要对该区域的电气设计进行简要介绍。

The anaerobic jar produces biogas,which is mainly composed of methane.Methane is flammable gas,therefore the area of anaerobic jar is explosive gas atmosphere.The electrical design for this area mainly includes the division of hazardous area,equipment selection,power distribution,cable laying,equipment installation,lightning protection and earthing,etc.The paper briefly introduces the electrical design of this area.
