摘要
随着工作面功率的加大,矿井电压过低造成设备启动困难或不启动现象,甚至造成欠电压跳闸,因此1140V电压等级升高到3300V将是煤矿发展的前进方向。
With the working power increasing, low voltage in the mine causes start difficulty or start failure of equipment or even undervoltage tripping. So it is the development direction of the mine to increase the voltage from 1140V to 3300V.
