本发明属于电子技术,也就是当工作场所存在有爆炸性粉尘、瓦斯与空气混合物的危险时,例如在矿井、石油开采和化学工业企业等等,作为电气设备供电用和在矿井中防止爆炸危险火花产生的安全技术方法.很明显,装置是借助于快速动作可控硅分流器来保证供电电源输出电路的安全火花性能,当产生过我时,利用此分流器将输出端短路,以防止爆炸危险火花发生的可能性.除可控硅分流器外,它还包括在一定时间内关闭可硅控分流器的恢复电路,使防火花装置恢复工作状态.
The present invention pertains to the field of electronic technology, that is, when there is a risk of explosive dust, mixtures of gas and air present in the workplace, for example in mines, oil extraction and chemical industries, etc., as electrical equipment for power supply and for preventing explosion hazard in mines Generated by the safety technology method.It is clear that the device is by means of fast-acting thyristor shunt to ensure the safety of the power supply output circuit spark performance, when produced me, use this shunt to short-circuit the output to prevent the risk of explosion The possibility of sparks, in addition to SCR shunt, it also includes a certain period of time can shut down silicon-controlled rectifier shunt recovery circuit, the spark device back to working condition.
