摘　　要：对三相五柱式没有平衡绕组(没有角接绕组)的YNa0联接组别的自耦变压器进行纵绝缘结构分析。针对自耦变压器自身结构特点,应用波过程及电场计算软件着重对高压线圈与调压线圈(不同结构)主纵绝缘结构进行计算,最终确定线圈形式、匝绝缘厚度、段间油道等结构参数,并对其绝缘弱点区域采取了绝缘加强措施,保证了绝缘结构的安全可靠。The paper analyzed the longitudinal insulation structure of three-phase five limbs core without balance winding(without corner joint winding)YNa0 connection group autotransformer.Aiming at the autotransformer’s feature,this paper calculated main and longitudinal insulation structures of high tension coil and regulating coil(different structure)with the wave process and electric field simulation software,and finally defined the structural parameter such as coil format,interturn insulation thickness,oil gap between windings disks and so on.The insulation measures were strengthened in those weak insulation areas to ensure the safety and reliability of insulation structure.
