摘　　要：用模拟电荷法计算绝缘筒轴线的电场分布， 研究５００ｋＶ无分压电容器组合式光学电流电压传感器电场信号的取样方式并讨论了均压环的设置对电场分布、绝缘结构、传感点信号灵敏度的影响， 传感位置的选择， 绝缘筒热胀冷缩对信号准确度的影响及传感器的安装方式，This paper describes the calculation of electric field distribution on 500kV OMU using charge simulation method, and studies the sampling method of electric field signals of sensor of OMU. The influence of grading ring on the field distribution, insulation structure and sensitivity of sense area are discussed. The selection of sense position and its installation are also proposed.
