摘 要: 近几年来煤矿瓦斯事故不断发生。瓦斯已经成为煤矿企业的最重要的自然灾害之一。而贺西矿是高瓦斯矿井,瓦斯治理尤为重要。本文通过对贺西煤矿井下局扇双三专供电的原理进行分析,对贺西煤矿井下局扇双三专供电进行了改进,为了实现风电闭锁和瓦斯电闭锁功能,在每路风机的开关电源侧分别安装一台智能型断电仪,分别为各自的风机服务,受控于监测系统的地面中心站。每一组风机开关的常开接点与断电仪常闭接点串联形成输出的控制线路与另一组风机形成的控制线路并联,这样的话就实现了风电闭锁和瓦斯电闭锁功能。而且,为了风机的切换方便,采用了主副局扇自动切换的方式,当主局扇突然停止运转时,副局扇自动启动,且反应时间很短,从而保证了工作面的正常通风,使贺西矿井下局扇供风基本实现不间断供风,消除了井下采掘面瓦斯超限的安全隐患,并且已经在贺西矿得到了广泛的应用。
关 键 词: 矿山电气工程;瓦斯;局扇;双三专电源;风电闭锁

Abstract: In recent years the gas accidents have occurred frequently. Coal mine gas enterprises is the most important one of the natural disasters. Hexi Mine is a high-gas coal mine gas control is particularly important. In order to achieve wind power and gas, locking locking function, in every way the switching power supply-side fan installing a smart-power device, respectively, for their respective fan, controlled by the central monitoring system of ground stations. Each fan switch normally open contact with the off-form series regular contact closure output of the control line and another group of fans formed the control of parallel lines, so to achieve a closed wind power and gas, locking function. Furthermore, in order to facilitate the fan switch, a deputy bureau chief of the main fan automatically switch the way, when the main fan suddenly stopped functioning, the deputy bureau chief fan automatically activated, and the reaction time is very short, so that the face of normal ventilation, based on the Hexi Coal Mine Bureau double-fan power supply three of the analysis of the principle of the coal mine-Hexi three of the dual-fan power supply was improved so that the underground mine-Hexi Wind fan for the basic realization of uninterrupted for wind, the elimination of underground mining of the gas gauge potential safety problems, and has been in the Hexi Mine had wide applications.
Key words: mine electrical engineering; natural gas; fans; the two-three powe; wind power artesian
