摘要
Abstract
The proportion of the coal mine power supply system override trip caused by voltage lfuctuation, electrical interference, poor protection and switching performance is much higher than that of the short circuit overcurrent. Override trip will cause underground blackout, the ventilation system, production system will stop running, and result in signiifcant production safety problems. Based on many years of practice, the reasons of override trip in coal mine power supply system were comprehensively analyzed, some preventive measures and were put forward, Finally, the new technology to solve the tripping are discussed.关键词
