摘要针对干式空心电抗器高电压和强磁场的极端环境,采用埋入式光纤布拉格光栅测温技术,实现了对35 kV干式空心电抗器工作状态下的温度监测。研制出一种结构简单、体积小且抗电磁干扰的光纤布拉格光栅温度传感器,将传感器埋在导线外包封层表面相邻两根通风条之间,距离电抗器上沿约40 cm。温升实验结果表明,达到稳定状态后,最内导线层与最外导线层温度较低,分别约为82 ℃ 和72 ℃;中间各层温度相接近,分布在90～100 ℃之间,其中第6导线层温度最高约为100 ℃。埋入式光纤布拉格光栅温度传感器稳定可靠、准确度高、抗电磁干扰,能够实现极端环境下对35 kV干式空心电抗器温度的在线监测,对维护电网的安全稳定具有重大意义。

Abstract：High temperature seriously threatens the security and the stability of the dry-type air-core reactor operation.In this paper,concerning its extreme high voltage and strong magnetic field environment,the temperature monitoring for the 35 kV dry-type air-core reactor under the working condition using embedded (fiber Bragg grating) FBG is implemented.An optical FBG temperature sensor with the characteristics of simple structure,small volume,and electromagnetic interference resistance is developed.The sensor is then buried in the lead sealing surface casing between two adjacent ventilation bars.The distance to the top of the reactor is about 40 cm.The temperature experimental results show that,after reaching steady state,the temperature of the inner conductor layer and the outer conductor layer are relatively low,about 82 ℃ and 72 ℃ respectively,and the temperatures in the middle are distributed between 90 ℃ and 100 ℃.The highest temperature of the conductor layer 6 is about 100 ℃.The designed embedded optical FBG temperature sensor is stable and reliable,with high precision and electromagnetic interference resistance.It can realize the on-line temperature monitoring in the extreme environment for 35 kV dry-type air-core reactors,and is vital to maintain the security and stability of the power grid.

Key words： Dry-type air-core reactor optical fiber Bragg grating embedded type temperature measurement on-line monitoring
