    摘要:

    研究了使用光纤光栅传感器监测电力变压器中变压器油的降解。与新的变压器油相比,老化的变压器油有较高的折射率,这可被光纤光栅传感器光谱响应的波长偏移检测出来。结果表明符合击穿电压测试,该测试是变压器油老化检测的标准测试,同时该传感器与温度无关。

    Abstract:

    The degradation of transformer oil in power transformer using fiber Bragg grating sensor was discussed. The survey results showed that aging transformer oil had a higher refractive index compared to fresh transformer oil. This could be detected by the wavelength shift of the spectral response of fiber Bragg grating sensors. The results complied with the breakdown voltage test which was the standard test of transformer oil aging detection. The sensor was independent with temperature in the mean time.
