通过对GVPI高压交流电动机无防晕系统的定子绕组线圈槽部与端部结构进行分析，建立了相应的电路模型，对定子绕组的介质损耗因数（tanδ）与电容（C）随施加电压(U)的变化关系进行了测试及分析，并将绕组介质损耗因数的理论计算值与实测值进行比较。结果表明：定子绕组的介质损耗因数及其增量与电容及其增量成正比，同时由模型电路计算的介质损耗因数与试验实测值基本一致。

By analyzing insulation structure of global vacuum pressure impregnation(GVPI) AC motor sta-tor winding without anti-corona system, we built a corresponding circuit model to test the change of di-electric dissipation factor(tanδ) and capacitance of stator winding with the voltage, and the calculation val-ue of dielectric dissipation factor of stator winding was compared with the test value. The results show that the dielectric dissipation factor and its increment of stator winding are proportional to the capacitance and its increment. The calculation value of dielectric dissipation factor is consistent to the test value.
