摘要
用理论分析和计算机仿真的方法研究了环境温度变化导致的光源中心波长移动和传感头材料Verdet常量与应力双折射变化对光学电流互感器输出性能的影响·结果表明:环境温度由10℃变化到30℃时,归一化尺度因子降低了1.379%·其中光源中心波长随温度的变化对输出尺度因子的影响大于其他光学参量温度特性的影响·因此,在光学电流互感器设计中,必须采取必要的技术措施减小或补偿传感头温度特性对系统的不利影响·
The effects of the central wavelength shift of the source and the variations of the parameters of the sensing head （Verdet constant and linear birefringence） due to ambient temperature fluctuation upon the scale factor of a bulk-glass optical current transformer are theoretically analyzed and digitally simulated. The results show that the normalized output scale factor will decrease 1. 379%, when the ambient temperature changes from 10℃ to 30℃, among which the effect of the central wavelength shift with temperature upon the scale factor is greater than the others. Therefore, it is necessary to adopt proper technical measures to decrease or compensate the undesirable effects of the temperature characteristics of the sensing head.
