摘　　要：采用一种光纤布拉格光栅三维拉力传感器对变电站高压套管的安装方式进行了测试,并对套管端部受力状态进行了长达1500h的长时间监测。通过测量不同安装方式下套管端部的受力,优化了引下线方式和金具安装类型;对套管端部受力进行长时间监测,得到套管端部存在三维拉力和温度引起的热应力的结果,并在三维力中得到可能为风载荷加载在跨线上引起变电站结构晃动的低频信号频率为0.18Hz和0.22Hz。基于光纤布拉格光栅三维拉力传感器,初步实现了对变电站的健康监测,推动智能电网的发展。Three-dimensional(3D)tension sensor based on fiber Bragg grating(FBG)is used to test the installation state of high-voltage bushing in substations,and the stress state of the bushing end is continuously monitored for 1500 h.By measuring the stress at the end of the bushing under different kinds of installation,the arrangement of the down line and fittings installation type are optimized.By monitoring the stress at the end of the bushing for a long time,the 3D tension and the thermal stress due to temperature changing at the end of the bushing are measured.Low-frequency signals(0.18 and 0.22 Hz)are obtained from the 3D tension,which are due to substation shaking resulting from the wind load on the cross line.The health monitoring of the substation is preliminarily realized by the 3D tension sensor based on FBG,which can further facilitate the development of the smart grid.
