摘要:
分析近年来煤矿重大瓦斯事故,多是由于主扇或局扇无计划停电停风后不能及时恢复送电,造成瓦斯积聚、超限,最终导致瓦斯爆炸,这对煤矿的安全生产运行产生重要影响。实践证明,采用依据煤矿供电系统特点研制而成的矿用电源快速切换装置,可显著提高供电系统的可靠性,确保风机的不断电运行,在一定程度上达到煤矿本质安全的目的。

Abstract:
According to the analysis of coal mine gas explosion accidents in recent years,the main reason is that the main ventilator was unplanned outage, power supply failed to recover in time, resulting in the accumulation of gas is over the limit, eventually lead to gas explosion, which have an important influence on the safety operation of coal mine.It has been proved that, the power supply rapid switching device developed for mine, can significantly improve the reliability of power supply system, ensure the continuous operation of the ventilators, reach to the purpose of intrinsic safety in coal mine in a certain extent.
Key words: mine, rapid switching device, gas explosion, ventilator, power supply system, grade trip
