摘要
为了提高局部通风机供电安全性,提出在局部通风机上加装应急电源。该方案的提出可以启动应急电源为局部通风机提供动力,在双电源故障的情况下,最大限度地减少因电源故障造成的瓦斯积聚或爆炸事故,还可以大大提高局部通风机供电的安全性。
In order to improve the safety of local ventilation fan power supply,the addition of emergency power supply to the local ventilation fan is proposed.The proposed scheme can start the emergency power supply to provide power for the local ventilator and minimize the gas accumulation or explosion accident caused by power failure in case of double power failure which is to improve the safety of ventilation.
