【摘要】 以琼斯矩阵为数学工具,利用理论分析和计算机仿真的方法研究了单层保偏反射膜反射相移的色散特性和光学玻璃的Verdet常数色散特性以及它们对光学玻璃电流互感器灵敏度的综合影响。结果表明:这种影响可使互感器输出波动超出国家技术标准的要求。因此,应对光源采取恒温控制,并对光源驱动电流恒流控制或对系统输出结果采取补偿措施。更多还原

【Abstract】 The dispersion properties of the reflection phase shift of polarization-preserving reflecting medium layers and Verdet constant of optical glass and their joint effects upon the sensitivity of a bulk glass optical current transformer are theoretically analyzed by taking Jones’ matrix as a mathematical tool and simulated with a computer.The investigation results show that the effects will make the output fluctuation beyond the requirements of the concerned national technical standard.Therefore,it is necessary to stabilize the driving current and the ambient temperature of the optical source or compensate the output of the system by some technical means.更多还原
