摘　　要：全光纤电流互感器(FOCT)系统中λ/4波片的相位延迟角容易受环境温度的影响使FOCT产生测量误差,传感光纤中的线性双折射会影响光的偏振状态也会使FOCT产生测量误差。针对以上2个问题,分析了FOCT的测量精度和环境温度的关系,提出了一种温度性能优化方法;分析了FOCT的测量精度和线性双折射的关系,提出了一种合理确定传感环几何参数的方法,并在Labview平台上对温度性能优化方法的有效性进行了仿真验证。The λ /4 wave plate phase retardation is easily affected by the environment temperature,and it makes FOCT produce the measurement errors,and the linear birefringence in the sensing fiber affects the polarization state of light,and it also makes the FOCT produce measurement errors.Considering the two influence problems,the paper analyzed the relationship between the measurement accuracy and the temperature of the environment,and proposed a method to optimize the temperature performance of FOCT; the paper analyzed the relationship between the measurement accuracy and the linear birefringence,and proposed a method to determine the geometric parameters rationally,and verified the validity of the optimization method by Labview simulation.
