随着我国煤炭工业的发展,为煤矿服务的矿用防爆电器制造业也不断增多,因而防爆电器的设计、制造、检验、维护者们也就需要更多、更系统的关于防爆电器的理论知识。当我们欣喜读到《矿用防爆电器设计、制造、检验、维护知识讲座》(以下简称《讲座》)后,认为该《讲座》很有现实意义。首先《讲座》改变了“通用电器+防爆外壳=矿用防爆电器”的传统观念,而煤矿的具体环境所需要的电器,正是《讲座》中明确提出的“矿用电器+防爆外壳”才是矿用防爆电器这一新的观念。另外《讲座》介绍了由于煤矿的特定环境决定的矿用防爆电器产品技术条件的制定,给设计者以明确而又细腻的指导。其次,对于快速开门式矿用防爆电器产品是煤矿深受欢迎的。其原因是我国目前生产的电器元件
With the development of China’s coal industry, mine explosion-proof electrical equipment manufacturing services for the mine are also increasing, so the design, manufacture, testing, maintenance of explosion-proof electrical appliances also need more and more systematic theoretical knowledge of explosion-proof electrical appliances . When we are delighted to read the “mine explosion-proof electrical design, manufacture, inspection, maintenance knowledge seminar” (hereinafter referred to as “seminar”), that the “seminar” is of great practical significance. First of all, “Lecture” changed the traditional concept of “General Electric + Explosion-proof Enclosure = Explosion-proof Electrical Apparatus for Minerals.” However, the electrical appliances required for the specific environment of a coal mine are just the “Explosion- Mine is explosion-proof electrical appliances this new concept. In addition, ”Lecture" introduced due to the specific environmental coal mine explosion-proof electrical products, technical conditions, to give designers a clear and detailed guidance. Second, the rapid open-door mining explosion-proof electrical products is popular coal mine. The reason is that China’s current production of electrical components
