摘要
温度监测是预防电力电缆大量使用引发事故的常规方法,通过对国内外4种常用电力电缆测温技术的分析,认为光纤光栅温度传感技术抗电磁干扰能力强,布置灵活,可实现多目标温度的快速准确测量;阐述了光纤光栅传感器的测温原理;实际应用表明,利用光纤光栅传感器监测电力电缆温度安全可靠、精度高、监测距离远。
Temperature measurement is the conventional technique to prevent cable accidents caused by use of cables in abundance.By analysis of four common cable temperature measurement techniques both here and abroad,fiber grating sensing technique is considered to be well capable in anti-electromagnetism,flexible in configuration and realizable in multi-objective fast and accurate temperature measurement.The paper also expounds temperature measurement principle of fiber grating sensor.The application indicates that fiber grating sensor in cable temperature measurement system is characterized by its safety and reliability,high accuracy and remote monitoring distance.
