摘　　要：基于光纤光栅传感技术设计了一种用于监测变电站套管受力状态的光纤光栅三维拉力传感器.通过有限元仿真和实验测量结合的方式,实现了三维拉力传感器解调的设计和测试,在3个方向的灵敏度为0.01~0.02με·N-1.对传感器进行加载测试,测试结果与加载结果基本一致,在600 N加载范围内平均误差为5.13%,光纤光栅三维拉力传感器能够实现对三维拉力的准确测量.A three-dimensional tension sensor based on fiber Bragg grating sensing technology is designed to monitor the stress state of substation bushing. In combination with finite element simulation and experiment, the three-dimensional tension sensor is implemented and signal demodulation is realized. It is shown that the tension sensitivities in three directions of the sensor are all between 0.01με·N-1 and 0.02 με·N-1, loading test results are basically consistent with the values of added load, and the average error of the sensor is 5.13% for the load of 0~600 N. Therfore, the proposed tension sensor based on fiber Bragg grating is applicible in the measurement of three-dimensional tension with high accuracy.
