摘要 本文研制了一种基于光纤光栅的振动传感器,可应用于油浸式变压器中的振动信号测量。文章首先描述了此传感器的原理结构以及其在变压器的特殊环境中测量振动信号的优势。通过模拟振动实验,进行了空载和油浸两种情况下传感器的性能测试,在油浸环境下,其测量振动信号的动态范围为400 Hz,测量精度可达1 Hz。最后在变压器绝缘油中进行温升实验,从40℃~100℃温度范围内,都能准确测量振动信号。 A vibration sensor based on fiber Bragg grating is proposed for the measurement of vibration sig-nals in oil-immersed transformers. This paper firstly describes the principle structure of the sensor and the advantages of the vibration signal in the special environment of the transformer. Through the vibration simulation test, no-load and oil two kinds of sensor performance test and under oil immersion environment, the measured vibration signal dynamic range for 400 Hz, the measurement accuracy is up to 1 Hz. Finally, the temperature rise experiment is performed in the transformer insulation oil, and the vibration signal can be accurately measured from the temper-ature range of 40?C - 100?C.
