摘要
介绍了一种对旋风机智能化微机保护器,该保护器以单片机为核心,具有漏电、过载、断相、短路等多种故障自动诊断及串行通信等功能,对掘进工作面不间断通风和风电、瓦斯电闭锁。经实际应用,效果良好。
In this paper, an intelligent microcomputer protective device taking the single chip microcomputer as core for disrotatory fan is introduced. The device has the functions of automatically diagnosing fault such as leakage, overload, short phase and short circuit as well as serial communication, which realizes blocking of wind power and gas power in heading face.
