摘要
《煤矿安全规程》规定煤巷、半煤巷掘进工作面必须实现瓦斯电锁闭。针对瓦斯电锁闭功能的实现,本文提出了两套方案:一种是改造BGP系列矿用隔爆型高压真空配电装置,以实现瓦斯电锁闭;另一种是利用一种新装置—JDQB-1J型装置来实现瓦斯电锁闭。这对提高系统的可靠性具有重要意义。
〈The coal mine safety regulations〉is heading roadway, half coal roadway terms must realize gas itinerary. For gas electric locking function, this paper puts forward two schemes： one is the improvement of BGP series flameproof high--voltage vacuum distribution device, in order to achieve gas itinerary; another is to realize gas lock closure using a new device of JDQB-1J type device. It is of great significance to improve the reliability of the system.
