老矿井采区供电电压提高方案

A Design to Raise Supply Voltage at the Working Face of an Old Coal Mine

老矿井采区供电电压不稳常会造成设备起动困难甚至不能起动,有时还会发生运行中的设备启动装置欠电压跳闸,严重威胁矿井安全.本文采用建设升压站提高采区供电电压,成功地解决了老矿井采区变电所电压偏低的问题,稳定了电压,大大提高了供电质量,保证了设备的正常起动和运转,为安全生产提供了强有力的保障.

If the supply voltage is unstable at the working face of an old coal mine, it can make equipment difficult to start and can cause operating equipment to trip due to undertension. This article proposes to build a step-up substation to raise the supply voltage at the working face in order to solve the problem of low voltage and voltage instability. Furthermore, the implementation of this proposal will improve the quality of the power supply, ensure the proper operation of equipment, and provide a strong guarantee for safety.
