摘要
准确测量变压器内部温度具有重要研究意义。但测量变压器内部温度,不仅存在测量难度大的问题,而且测温点少。因此,提出了一种基于光纤光栅传感器的变压器卷铁心温度监测方法。将光纤光栅传感器嵌入变压器铁心,采用空分复用和波分复用的方法将传感器信息传入解调仪,解调仪将波长信号转换为数字信息并传入计算机,实现实时监控功能。仿真结果表明,与电信号传感器测量法(Electrical Signal Sensor Measurement,ESSM)、红外测温法(Infrared Temperature Measurement,ITM)及光纤测温法(Fiber Optic Temperature Measurement,FOTM)相比,光纤光栅卷铁心温度测量法(Fiber Grating Core Temperature Measurement,FGCTM)能有效提高变压器内部温度的检测精度。
Accurate measurement of the internal temperature of the transformer has important research significance.However,the problem of measuring the internal temperature of the transformer and the small temperature measurement point has been plagued by researchers. To solve this problem,this paper proposes a transformer core temperature monitoring method based on fiber Bragg grating sensor. Firstly,the fiber grating sensor is embedded in the transformer core. The method of space division multiplexing and wavelength division multiplexing transmits the sensor information to the demodulator,and the demodulator converts the wavelength signal into digital information and transmits it to the computer to realize the function of time monitoring. The simulation results show that compared with the Electrical Signal Sensor Measurement(ESSM),the Infrared Temperature Measurement(ITM) and the Fiber Optic Temperature Measurement(FOTM),the fiber grating proposed in this paper is compared. The Fiber Grating Core Temperature Measurement(FGCTM) can effectively improve the detection accuracy of the internal temperature of the transformer.
