Multilayer cylindrical transformer winding

The utility model discloses a multi-layer cylindrical transformer winding which comprises an inner layer, a plurality of winding layers are wound on the inner layer, an interlayer insulator is arranged between every two adjacent winding layers, an outer layer is wrapped outside the outermost winding layer, end insulators are respectively arranged at two ends of each winding layer, the end insulators and the interlayer insulators are bonded, and the outer layer is wrapped outside the outer layer. The winding layer is formed by spirally winding metal wires, the cross section of each metal wire is in a flat oval shape, every two adjacent circles of metal wires are tightly attached to each other, the structure is reasonable, and the problems that a winding is low in filling rate and low in mechanical strength are solved. 本实用新型公开了一种多层圆筒式变压器绕组，包括内层，内层上绕制有若干层绕线层，相邻两个绕线层之间设置有层间绝缘，最外层绕线层的外部包裹有外层，每层绕线层的两端分别设置有端绝缘，端绝缘和层间绝缘粘接，绕线层为金属导线螺旋绕制而成，金属导线的横截面为扁椭圆形，且相邻两圈金属导线相互紧贴，本实用新型结构合理，解决绕组填充率低和机械强度弱的问题。
