根据中波科技合作协定,中国矿山电气——井下供电考察组于1983年12月4日至24日赴波兰对煤矿井下供电系统进行了技术考察。自1977年以来,波兰煤矿井下千伏级供电系统及矿用电气设备有较大发展,简述如下: 一、1000V供电系统逐步得到推广从七十年代采用1000V供电以来,至今井下电气设备用1000V和500V的约各占50％,估计在全国64个矿井中: 井下全部采用1000V供电约12个采区采用1000V供电约25个工作面采用1000V供电约25个由于1000V供电有明显的技术经济效益,所以在推广过程中很少有阻力。
According to the China-Poland Science and Technology Cooperation Agreement, the Chinese mine electrical-underground power supply inspection team went to Poland from December 4 to December 24, 1983 to conduct a technical inspection on the coal mine power supply system. Since 1977, there has been a great development of the kilowatt-class power supply systems and mine electrical equipment in the underground coal mines of Poland. The brief introduction is as follows: 1. The 1000V power supply system has been gradually popularized. Since the 1000V power supply in the 1970s, up to now, And 500V about 50% each, estimated at 64 mines in the country: all underground using 1000V power supply about 12 mining area using 1000V power supply about 25 working face using 1000V power supply about 25 1000V power supply has obvious technical and economic benefits , So there is little resistance in the promotion process.
