摘要(Abstract)：

针对变压器绝缘油微水测量不准确造成的变压器故障，通过理论推导、数值仿真和实验测量，设计了λ/2微波同轴谐振腔传感器，利用HFSS仿真软件对同轴谐振腔进行仿真设计，同时进行了绝缘油微水测量实验，得出当微水体积分数小于50×10~(-6)时，测量误差在2%以内，验证了同轴谐振腔传感器测量变压器绝缘油微水的可行性，实现了绝缘油微水的精准监测。
Aiming at the transformer faults caused by inaccurate measurement of the insulating oil moisture content in the transformer, a λ/2 microwave coaxial resonator sensor is designed through theoretical derivation, numerical simulation and experimental measurement. At the same time, HFSS simulation software is used to simulate and design the coaxial resonator, and the insulating oil moisture measurement experiment is carried out. The results show that when the moisture content is less than 50×10-6, the measurement error is less than 2%, which verifies the feasibility of measuring transformer insulating oil moisture with coaxial cavity sensor and realizes accurate monitoring of insulating oil moisture.
