摘　　要：光学电流互感器作为电力系统换代产品具有突出的优点 ,但其传感部分易受温度影响为其最大弱点。文章简要介绍了其工作原理 ,对温度影响的原因作了理论分析 ,并有针对性地进行了多方面的试验 ,最后给出了温度影响的试验结果。As a kind of new generation product of the electrically system.The OCT is possessed of prominent advantages,but its transducer part is easyly effected by temperature influence.That is its main weakness.This paper introduces its working principle,analyses in theory the reason of the temperature influnce and carries out experiments correspendingly in many ways.At last,the resutls of the experiments of the temperature influence are given out in this paper.
