摘　　要：根据光学电流传感器的开环机理,只有从外部为光学电流传感器引入新的独立量才能消除环境温度等外因的影响以实现高精度测量。论文提出了一种新的独立量自适应光学传感理论,即通过对两组或两组以上的独立输出量进行自适应运算获得与干扰无关的测量结果。应用该理论设计了光路独立量自适应光学电流传感器和光电独立量自适应光学电流传感器。并以标准检测系统为测试平台对光电独立量自适应光学电流传感器的测量性能进行了检测,结果证明该传感器已达到了0.2级的测量水平。Because of the open loop characteristic of optical current transducer (OCT), the only way to eliminate the influence of external factors such as environmental temperature is to lead the external independent variables into OCT to realize the measurement with high accuracy. Here, a new adaptive optical transducing theory based on independent variables is proposed, i.e., by means of the adaptive operation of two groups or more independent output variables the measured results which are not related to the interferences can be obtained. By use of above-mentioned theory, the adaptive OCT based on independent variables in light path and the adaptive OCT based on optoelectric independent variables are designed. Taking the standard authoritative detecting system for testing platform, the measuring performance of the adaptive OCT based on optoelectric independent variables is detected. The detection results show that its measurement accuracy reaches the measuring level of 0.2 grade.
