摘　　要：建立了均压环的漆膜与均压电容器串联的电路模型,模型的分析结论与测量结果相符,验证了模型的正确性。实例计算表明漆膜的电容量和介损值很大,因此在测量中要尽量避免漆膜的影响,测试线要接在金属接触良好的位置。This paper establish the model for paint film of grading ring and grading capacitor.The conclusion of model is according with the measuring data,which verify valid of the model.It indicates that paint film has obvious affection to measuring grading capacitor＇s dielectric loss according to calculating the test date.Thus measuring line should connect with the naked metal of grading capacitor to avoiding affection of the paint film.
