摘　　要：试验并分析了复合绝缘子均压环对电场分布的影响。指出复合绝缘子沿面场强和电压分布极不均匀 ,高压侧芯棒在高场强作用下的电老化和化学腐蚀是芯棒脆断的重要因素。根据确定均压环参数的要点 ,推荐了 330 kBased on test results, this paper analyzes the effect of grading ring of polymer insulator on the field distribution. It is presented that the surface field distribution and the voltage distribution is strongly non uniform and the electrical ageing and the chemical corrosion of H.V.end of FRP rod by high field are important reason of brittle fracture of FRP rod. The main points establishing the structure parameters of grading ring are introduced. Furthermore, the parameters of grading ring used on 330 kV polymer insulators are recommended.
