光纤测温系统在煤矿供电系统的应用

Application of Optical Fiber Temperature Measurement System in Coal Mine Power Supply System

煤矿井下电缆或高低压开关设备着火引发的重大火灾事故严重威胁煤矿安全,针对煤矿井下电气火灾事故的主要原因及特点,提出采用分布式光纤测温技术对井下供电系统全方位进行温度监测预警,甚至对于部分非一类重要负荷可在升温幅度达到燃点之前给予断电闭锁的反馈控制方案。本文讨论了光纤测温系统的原理结构、实施方案,以及光纤测温系统对煤矿供电安全的重要意义。

major fire accidents caused by coal mine underground cable or high and low pressure switch equipment fire seriously threaten coal mine safety, aiming at the main causes and characteristics of coal mine underground electrical fire accidents, In this paper, distributed fiber optic temperature measurement technology is used to monitor and warn the underground power supply system in all respects, even the feedback control scheme of power outage can be given before the temperature increase reaches the ignition point. This paper discusses the principle structure, implementation scheme and the significance of the optical fiber temperature measurement system for coal mine power supply security.
