备用局部通风机开关警示红灯装置的研究与应用

Research and application of spare local fan switch warning red light device

为实时监控备用局部通风机供电是否正常,研究出备用局部通风机开关警示红灯装置,并在陈四楼煤矿的岩巷掘进工作面实施应用。该装置实现了对备用局部通风机的实时监控,避免风机双停事故,消除了备用局部通风机的潜在安全隐患。

For real-time monitoring of the operating state of the power supply of spare local fan, developed spare local fan switch warning light device, and application in rock heading face in Chensilou coal mine. The device has realized the real-time monitoring to the spare local ventilator, avoided double stop accident fan, and eliminated the potential safety hazard alternate local ventilator.
