一、推广煤电钻综合保护器的必要性过去,采掘工作面煤电钻经常出现烧毁,电缆被砸造成的漏地、短路等事故,直接影响生产和安全。根据《煤矿安全规程》407条的规定:“煤电钻必须设有检漏、短路、过负荷、远距离启动和停止煤电钻的综合保护装置。”我局选用了上海电器厂生产的BZ80-2.5Z 与淮南望峰岗煤机厂生产的 ZZ8L-2.5型(以下分别简称为 BZ 和 ZZ 型)两种煤电钻综合保护器在全局推广使用,目前井下使用的340台煤电钻已全部配用综合保护器。经过近三年使用证明,综合保护器具有的短路、过载、远方停送电及漏地等
First, the promotion of integrated coal mine electric drill necessity In the past, coal mining drill face often appear burned, cable smashed caused by leakage, short circuit and other accidents, a direct impact on production and safety. According to “Coal Mine Safety Regulations” Article 407: “Coal electric drill must be equipped with a comprehensive protection device for leak detection, short circuit, overload, long-distance start and stop coal electric drill.” Our bureau chooses the BZ80 -2.5Z and ZZ8L-2.5 (hereinafter referred to as BZ and ZZ respectively) manufactured by Huainan Wangfenggang Coal Mine Machinery Factory are widely used in the global promotion. Currently, 340 coal-fired power drills All equipped with integrated protector. After nearly three years of use proved that the integrated protection has a short circuit, overload, stop power and so far to leak
