煤矿井下电气设备防爆探讨

Exploration on Explosion-proof of Electrical Equipments Underground in Coal Mine

煤矿井下含有瓦斯、煤尘,当达到一定量值时遇有电弧、电火花及局部高温时,将会引起燃烧和爆炸。因而井下电气设备必须具有防爆性能,又要保证爆炸后不会使设备外壳变形。本文主要阐述了煤矿井下电气设备的防爆途径、防爆电气设备的应用技术及电气防爆管理等问题。

The underground well of coal mine contains fire damp and coal dust,when reaches a certain level,meeting the electric arc,spark or the local high temperature will cause fire and explosion.Therefore,the underground electric equipment must have the performance of explosion prevention,but also to ensure the equipment will not deform after explosion.The paper mainly discusses the explosion-proof methods of coal mine underground well electrical equipment,the application technology of explosion-proof electrical equipment and electrical explosion-proof management.
