摘　　要：详细分析矿井采用无功补偿进行节能降耗的重要意义,并从理论研究方面分析了采用无功补偿技术进行节能的原理。以井下变电所250 k W电机为例进行无功补偿实践,结果显示采用无功补偿后节能降耗效果明显,说明无功补偿在煤矿中的应用具有较好的前景。This paper made detailed analysis of the importance of saving energy and reducing consumption by using reactive compensation in coal mines, and analyzed the principle of reactive power compensation technology that is adopted to improve the energy saving from the aspects of theoretical research. Taking reactive power compensation practices in the underground substation 250 kW motor as example, results showed that the energy saving effect is obvious after using reactive power compensation, and reactive power compensation in the coal mine application has good prospects.
