摘　　要：绝缘气体压力的变化对光电电压互感器的影响不可忽视 ,这是新的传感原理引出的新问题。本文分析了该影响的原因和表现形式 ,提出了减小影响的具体解决方法。理论分析及实验结果表明 :绝缘气体压力的变化对光电电压互感器准确度的影响可控制在± 0 .The influence of the insulation gas pressure change on optical voltage transformer couldn't be neglected. It's a new problem created by the new sensing principle. This paper has analyzed the reasons and patterns of the influence and given the methods to reduce the influence. Both theoretic analysis and experimental results show that the influence of the insulation gas pressure change on the accuracy of optical voltage transformer may be reduced to ±0.1%.
