在电流回路中，当通过导线的电流过高时，会导致线路高温，严重时可能引起火灾。因此实时监测电流线路的温度，对预防线路过载以及火灾的发生具有重要的意义。在理论分析光纤光栅温度传感机理的基础上，设计了用于导线负载检测的传感系统。在0~5A范围内，实验研究了光纤光栅温度传感器中心波长变化与导线负载之间的关系，验证了导线负载检测的可行性，为导线负载的实时监测，以及断路、短路故障的判断提供了一种新的方法。

In the current circuit, when the electric energy transmits in wire, the wire will generate heat be?cause of the high current through it, the high temperature will even result in a fire. Therefore, monitoring the current of the wire has important significance for the prevention of the overload and the fire of the wire. Based on the related theories of optical fiber grating temperature measurement, a sensing system for wire load detection is designed. The relationship between the changing of the center wavelength of the fiber grating temperature sensor and the wire load in 0~5 A is researched in experiments, Experimental results show that wire load detection is feasible and provides a new method for real-time monitoring of wire load and the judgment of open and short circuit fault.
