煤矿井下低压无功补偿技术探析

Discussion on Low Voltage Reactive Compensation Technology for Coal Mine Underground

煤矿井下电网普遍存在功率因数偏低的问题,造成供电系统电压降加大和无功电流增大,使得电气设备启动困难,无功损耗严重。论述了煤矿井下低压供电系统无功现状以及无功补偿技术在井下的发展应用情况,并且阐述了TSC井下低压无功补偿装置的设计思想。

The problems of lower power factor exist in the electric network of coal mine underground, which leads to the power supply system increase and reactive current increase, make electric equipment start difficultly and reactive loss se-rious. The paper discribes the reactive conditions of the low vohage powper supply system for coal mine underground and the development of reactive compensation technlogy and give a design idea of the low voltage reactive comcpensation de- tvice for TSC underground.
