Mining electric energy quality on-line detection system

The invention relates to a mining electric energy quality on-line detection system, which comprises a mining explosion-proof and intrinsically safe electric energy quality on-line detection device, anexplosion-proof mutual inductor, a mining communication base station and a mining network switch. According to the system, detection points can be arranged in each underground power supply facility;full coverage of coal mine underground power grid electric energy quality detection is realized; an underground special environment electric energy quality detection blind area in a coal mine power grid is eliminated; the underground coal mine power grid operation level is comprehensively reflected; the underground coal mine special electric energy quality problems (such as a coal mining machine,a scraper machine and a rubber belt conveyor) can be mastered; and a pollution source of the power grid electric energy quality can be positioned, so that reliable data support is provided for comprehensive evaluation of the co
