矿用防爆电器制造是为煤炭生产服务的重要行业,全国专门从事矿用防爆电器制造的生产厂大小不下百余家。各大矿务局和大型矿井的机修厂有的也生产矿用防爆电器产品。矿用防爆电器量大面广、品类繁多,估计全国年产值在3亿元左右。除老产品外,每年还有大量新产品投放市场。矿用防爆电器作为特殊电器之一,至今尚缺少专门著作较系统、完整、科学地论述其设计原理和设计方法,对其制造、检验和维护的专业介绍也不多见。造成矿用防爆电器的一次
Mine explosion-proof electrical manufacturing is an important industry for coal production services, the country specializing in mine explosion-proof electrical manufacturing plant size of no less than a hundred. Some major mining bureau and large mine mechanic factory some also produce mining explosion-proof electrical products. Explosion of large quantities of mine explosion, a wide range of categories, it is estimated that the national annual output value of 300 million yuan. In addition to the old products, there are a large number of new products on the market every year. Mine explosion-proof electrical appliances as one of the special appliances, there is a lack of specialized works more systematic, complete and scientific discussion of its design principles and design methods, manufacturing, inspection and maintenance of professional introduction is rare. Cause mining explosion-proof electrical time
