| 1. | Since for ages , most of the mine high voltage support system are adopted 6kv power over energy , but recent years , with the development of highly output , highly efficient technologies , with the widely adopted of a large number of heavy excavated equipments and high power lifting services , especially the dramatically increase in load under the well and the usage of 10 kv high pressure motors , 10kv high voltage supply has gradually become dominant power supply for coal mining power supply system
长期以来,我国煤矿高压供电多采用6kv供电系统。但近年来随着煤矿高产高效技术的发展,大量重型采掘设备和大功率提升设备被广泛采用,特别是井下负荷急剧增加,以及10kv高压电机的投入使用,使得10kv供电开始逐渐开始进入煤矿高压供电系统。 |
