国外工作面高压供电及对我国工作面供电升压的看法(上)

HIGH VOLTAGE SUPPLY ON COAL FACE IN FOREIGN COUNTRIES AND VIEWS ON VOLTAGE ESCALATION OF COAL FACE IN CHINA

文章介绍了80年代以来,国外日产万吨综采工作面供电技术的发展,列举了国外高产高效工作面机械装备的情况、单机容量、技术特征及其供电电压(2.3～5 kV)。作者结合我国具体情况,根据5点理由,认为我国采区供电升压宜分两步走:第一步先采用3.3kV,第二步再过渡到6kV。

The paper introduces the technique development of power supply on mechanical mining coal face at a daily output of 10000t in foreign countries since 80's, emunerstes the mechanical equipment, the capacity of single machine, the technical feature and the supplying voltage (2.3kV-5kV) of high production high efficiency coal face in these countries. In the light of the specific condition of our country, the paper proposes by reason of five points, the voltage escalation in mining area in our country ought to be taken in two steps, first escalate to 3.3kV and then to 6kV.
