【摘要】 论文回顾了光学电流互感器近年来的进展，分析了该技术领域存在的问题，报告了保偏反射膜温度特性对光学电流互感器的灵敏度性能的影响。在影响互感器灵敏度性能的诸多因素中，温度特性是一个关键的因素。故对保偏反射膜的温度特性进行测量对光学电流互感器的设计具有重要意义。然而对保偏反射膜的温度特性的测量，目前还鲜见报道。本论文旨在填补这方面研究的空白。在论文中作者提出了测量保偏反射膜的温度特性的方法，并从理论研究、计算机仿真、实验验证三个方面对这些方法进行了研究。研究发现：当温度发生变化时，光学电流互感器的灵敏度随之发生改变。因此，在实际系统设计中对光学玻璃电流传感头应采取必要的温度控制或补偿措施。更多还原

【Abstract】 In this paper the latest progress and existing problems in the field of optical current sensor is reviewed and analyzed, the effects of temperature features of polarization-preserving reflecting medium layer on sensitivity of a bulk glass optical current transformers(BGOCT) are investigated, the results are reported. The temperature features is one of the important factors that affect the sensitivity of OCS. The measurement of the temperature features of polarization-preserving reflecting medium layer is significant to the design of BGOCT. However, the report about the method of measuring the temperature features of polarization-preserving reflecting medium layer is rarely to seen. The aim of this paper is to fill the blank in this area of research. In this paper, the author proposes the method of measuring the temperature features of polarization-preserving reflecting medium layer and researches this method by means of theoretical analysis, computer simulation and experimental investigation. The results show that the system sensitivity changed in a certain range with the temperature varying. Therefore some technical means of temperature compensation of control to the BGOCT’s sensing head should be taken in the design procedures for practical systems.更多还原
