摘　　要：笔者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。A circuit model of grading ring＇s paint film in series with a grading capacitor is established. The analysis of grading capacitor＇s dielectric loss via the model is in accordance with the measurement, which verifies the validity of the model. The calculation result indicates that paint film has large capacitance and dielectric loss. Thus the measuring line should connect with the clean point of grading capacitor to avoid effect of paint film in measurement of grading capacitor＇s dielectric loss.
