基于圆柱螺旋光纤的杂散电流传感器研究
Study of stray current sensor based on cylindrical spiral fiber
摘要
Abstract
In order to solve the temperature sensitivity problem of stray current sensor, this paper proposes a rectangle sensitive loop based on a cylindrical spiral fiber. Firstly, the paper derives the Jones matrix of the rectangle sensor head based on the geometric rotation effect, combines with the structure of sensor, obtains the output representation of sensor. Then, it applies the genetic algorithm to optimize the characteristic pa-rameters of sensitive loop, which can be used to determine the optimization results. On these bases, the paper conducts the temperature experiments to test the performance of sensor. According to the results, the opti-mization results of the rectangle sensitive loop are that the length and the number of curve spirals are 1024mm and 35 in the long side while the two parameters are 876mm and 28 in the short side, the measurement error of the sensor is not greater than 0.4%.关键词
