我们覃李煤矿地处武鸣县北面,由双桥变电站用10千伏送电到矿场,距离30多公里,变压器低压侧只有280～300伏,最低只达到250伏。在这种情况下,矿井不但无法生产,就连抽地下水都不行。经常因电压低烧坏电动机,有时一天烧坏好几台,给生产带来很大的困难。为了大战一百天,完成上级交给的打800米运输大巷隧道工程的任务,克服电压低、电机停的被动局面,多出煤,支援工农业生产,在矿党委的领导下,学大庆,鼓实劲,勇于攻难关。我们吸取了外地的先进经验,用4.5千瓦电动机带一台50千
Qin Li coal mine is located in the north of Wuming County, Shuangqiao Substation with 10 kV power transmission to the mine, more than 30 kilometers away from the low voltage side of the transformer only 280 ~ 300 volts, the lowest only reached 250 volts. In this case, the mine can not only not produce, even pumping underground water will not work. Often the motor is burnt out because of the low voltage, and sometimes several burned several times a day, which brings great difficulties to the production. In order to achieve the goal of fighting 800-meter-long transport tunnel project, the task of overcoming the problem of low voltage and motor stop, extra coal to support industrial and agricultural production, under the leadership of mine party committee, to learn Daqing Drum strength, brave enough to storm off. We have learned advanced experience in the field, with a 4.5 kilowatts motor with a 50 thousand
