浅析煤矿低压线路熔断器电流的整定

Analysis of Current Setting of Fuse in Low-voltage Circuit in Collieries

熔断器作为煤矿井下低压过流保护装置之一,可以有效防止机电设备损坏,对于高瓦斯矿井可以有效防止矿井火灾、瓦斯煤尘爆炸等事故,所以对低压线路过流保护装置过流保护值的合理整定对矿井安全供电起着重要作用。

As one of low--voltage over current protection device underground coal mine, fuse can effectively pre vent the damage to electrical and mechanical equipment,accidents such as fire disaster and gas and coal dust ex plosion. So the reasonable setting of over current protection value of low--voltage circuit over current protection device plays an important role in safety power supply in coal mine.
