煤矿井下环境恶劣，湿度大，温度高，漏电和单相接地故障经常出现在低压电网中，容易导致煤尘、瓦斯爆炸。本文介绍了一种基于光纤通信的智能控制装置，控制信号采用光纤传输，利用光纤的防暴、抗干扰强等优点，比原始的智能控制更能有选择性的断开故障线路，减少停电范围，提高供电可靠性。
煤礦井下環境噁劣，濕度大，溫度高，漏電和單相接地故障經常齣現在低壓電網中，容易導緻煤塵、瓦斯爆炸。本文介紹瞭一種基于光纖通信的智能控製裝置，控製信號採用光纖傳輸，利用光纖的防暴、抗榦擾彊等優點，比原始的智能控製更能有選擇性的斷開故障線路，減少停電範圍，提高供電可靠性。

Under a harsh environment of high humidity and high temperature underground the coal mine, electricity leakage and single-phase ground fault are common occurrences at the low-voltage grid, which easily lead to coal dust and gas explosion. This paper describes an intelli-gent control device based on optical fiber communication, which transmit control signals through optical fiber by use of its advantages such as explosion-proof and disturbance-proof, so as to better selectively disconnect the fault line than the primitive intelligence control, lessening the power failure range and improve power supply reliability.
