基于电力光纤到户网络的电缆过热预警系统

The overheat warning system based on the Network of Power Fiber to the Home

电力光纤到户网络是一种使用光纤复合低压电缆实现光电同缆传输的场景,由于该种光纤复合低压电缆是一种将光传输单元和电缆复合而成的,缆线中电缆的温度会直接影响光传输单元的衰减,严重情况下,会导致通信中断。提出一种可以通过光纤的衰减来实时监测电缆温度异常并进行过热预警的系统,并对过热预警系统的装置、工作原理以及定位方法进行了分析和研究。

The Network of Power Fiber to the Home is a scene where optical fiber composite low-voltage cable is used to realize optical and cable transmission. The cable temperature will cause fiber attenuation because the optical fiber composite low-voltage cable is made up of optical fiber and cable. In serious cases, it can lead to network outage. Therefore, optical fiber attenuation can be used to monitor cable temperature abnormality in real time and carry out overheat warning.
