自动有载调压技术在延深矿井中的应用

Application of On-load Automatic Voltage Regulation in Deepened Mines

针对大同煤矿集团燕子山矿矿井延深后,原来6 k V供电系统因供电距离增长、设备装机容量增大存在电压下降严重的问题,分析了目前可能采用的提高电压方法,阐述了煤矿对自动有载调压装置的技术要求及其技术工作原理。根据燕子山矿供电及负载的实际情况,进行了设备配置,达到了显著的使用效果,为解决老矿井延深后高压供电问题提供了一种应用技术。

After deepening mines in Yanzishan Mine, Datong Coal Mine Group, voltage drop occurred with the increase of supplying distance and installed capacity of equipment of the old 6k V supplying system. The available methods to increase the voltage were analyzed. The paper presented the technological requirements of on-load automatic voltage regulation equipment and its working principles. Based on the supply and load of Yanzishan Mine, equipment configuration achieved obvious effects and provided an practical technology for the high-voltage power supply after the deepening of old mines.
