无线电控制瓦斯报警自动断电器主要适用于瓦斯浓度变化异常,有瓦斯爆炸危险的煤巷掘进工作面。用来自动监视瓦斯浓度的变化,当瓦斯浓度超限时,不仅发出声光信号,而且还能自动切断机电设备的电源,防止机电设备在瓦斯超限的条件下运行。当瓦斯浓度下降至允许值时,能自动送电或人工 Radio controlled automatic alarm gas alarm is mainly applied to abnormal gas concentration changes, there is the danger of gas explosion coal heading face. Used to automatically monitor the gas concentration changes, when the gas concentration exceeds the limit, not only sound and light signals, but also automatically cut off the power of mechanical and electrical equipment to prevent mechanical and electrical equipment in the gas over-limit conditions. When the gas concentration dropped to allowable value, can automatically send electricity or artificial
