DEVICE FOR PREVENTING GAS LEAK FIRE / EXPLOSION INCIDENT USING GAS SENSOR AND METHOD FOR CONTROLING THE APPARATUS

摘要

The present invention relates to an apparatus and method for preventing fire and explosion due to gas leakage by detecting a combustible gas sensor when a fuel gas such as LNG, LPG, or H ₂ leaks and controlling an alarm, a breaker, The gas sensor detecting the combustible gas; A detecting unit for amplifying and detecting an electrical signal detected by the gas sensor; And a control unit for controlling the alarm, the breaker, and the ventilator based on the detected signal, and a gas sensor for detecting the combustible gas; Comparing the concentration of the detected gas with the reference gas concentration; Generating an explosion warning if the concentration of the detected gas exceeds the reference gas concentration for a predetermined time; And controlling the breaker and the ventilator based on the concentration of the detected gas.
