摘要
煤矿井下电缆着火引发的重大事故严重威胁煤矿安全生产,针对煤矿井下电缆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电缆沿线温度进行监测预警,给出了分布式光纤测温系统的组成、原理和光缆布设方案,对保证井下电力系统的安全运行、煤矿安全生产有非常重要的意义。
The grave accident that Underground power cables ＇ fire invited threatening coal mine safety in production, aimed at the main cause and characteristics of underground cable conflagration accident, adopted distributed optic fiber temperature monitoring technology to early warning along the line , the composition, principle and sensing optical fiber assembly method of the temperature monitoring system based on distributed optic fibre sensing technology are presented. The system have very important meaning to ensuring that the underground electric system safety works and coal mine safety produces.
