在煤矿安全生产中,防止瓦斯爆炸,需抓好两个控制,一是控制瓦斯浓度,使其始终保持在《煤矿安全规程》允许的范围内:二是控制高温引爆源。安设瓦斯风电闭锁的目的就是当停风或瓦斯超限时,切断控制范围内所有非本质安全型电气设备及电缆上的电源,防止电气失爆引起
In coal mine safety production, to prevent gas explosion, need to grasp the two controls, one is to control the gas concentration, so that it always remain in the “coal mine safety regulations” allowable range: the second is to control the high temperature detonation source. The purpose of installing gas wind power lockout is to cut off the power supply on all non-intrinsically safe electrical equipment and cables in the control range when the wind stopped or the gas overrun to prevent electrical explosion
