Description

用于制造盘式绕组的方法
技术领域
本发明涉及一种用于制造盘式绕组的方法。一个优选应用在于干式变压器的高压绕组。 
背景技术
特别是在按照真空浇注技术制造的线圈的高压线圈领域中使用盘式绕组。在此，导体带(尺寸例如为20mm宽，0.2mm厚)与线匝绝缘体(例如30mm宽，0.1mm厚)彼此上下地卷绕成“盘”，其中所述绕组始端在绕组芯附近。例如在100线匝之后结束所述盘，该导体带被折叠90°并且在绕组芯方向上被往下引导成新的盘。在那里所述导体带重新被折叠90°并且其被卷绕成另一盘。这种盘式绕组能够由多个这种类型的、并排设置盘组成。在所述盘式绕组、或者该绕组的最后盘完成后以真空浇注法进行封装。 
发明目的 
本发明所基于的任务是，给出一种用于制造盘式绕组的优化方法。 
该任务按照本发明通过用于制造带有至少三个并排设置盘的盘式绕组的方法得到解决， 
·其中在卷绕过程内与绕组同时地在每两个盘之间制成中间绝缘体； 
·其中连接导体在中间绝缘体内以对角线形式从一个盘的末端延伸至另一盘的始端并且所述中间绝缘体借此分成两个分区，也就是带有三角形截面的第一中间绝缘区(其在对角线下方构成)和带有倒三角形截面的第二中间绝缘区(其在对角线上方构成)； 
·其中在从左往右推进的盘式绕组情况下，与盘的绕组同时地在盘左侧的第二中间绝缘区中安置绝缘体并且在盘右侧的第一中间绝缘区中安置绝缘体； 
·并且其中在从右往左推进的盘式绕组情况下，与盘的绕组同时地在盘右侧的第二中间绝缘区中安置绝缘体并且在盘左侧的第一中间绝缘区中安置绝缘体。 
利用本发明可获得优点尤其是在于，在卷绕过程内能够实现两个盘彼此间的所期望的连接走向，而在此不会产生很难用绝缘体、例如树脂粗纱卷绕的中空空间。借此在紧凑的、节省空间的构造情况下确保高压线圈或变压器的良好电气特性。 
本发明的有利拓展方案在从属权利要求中表征。 
附图说明
以下根据在附图中示出的实施例阐述本发明。其中： 
图1示出了在从左往右推进的盘式绕组情况下实施制备步骤期间盘式绕组的剖面的侧视图； 
图2示出了制成的盘式绕组的分区的侧视图； 
图3示出了制成的盘式绕组的侧视图； 
图4示出了从右往左推进的盘式绕组。 
具体实施方式
在图3中示出了制成的盘式绕组的侧视图。在示出例子中从左往右推进的、围绕绕组芯8的盘式绕组9具有四个盘，其中在盘式绕组9的各个盘之间分别设置有中间绝缘体。在此，也参考最初的、也适用于本发明的阐述。关于中间绝缘体这具体指： 
·在第一盘1和第二盘2之间设置有第一中间绝缘体A； 
·在第二盘2和第三盘3之间设置有第二中间绝缘体B； 
·在第三盘3和第四盘4之间设置有第三中间绝缘体C。 
下面详细论述中间绝缘体的制造。 
在此，在图1中示出了在实施的制备步骤期间从左往右推进的盘式绕组9的剖面的侧视图。在具体示出的、被实施的制备步骤中，第一盘1已经制成，而第二盘2刚被卷绕。在盘1、2之间设置有中间绝缘体A。每个盘具有(或应该具有)预规定数目的由导体带5组成的线匝，其中在每两个线匝之间有同样带形的线匝绝缘体6。该导体带5以连接导体7A形式连续地从第一盘1的末端引导至第二盘2的始端。在中间绝缘体截面内，该连接导体7A几乎相应于中间绝缘体A的对角线，所述对角线将中间绝缘体A分成两个分区，也就是 
·分成带有三角形截面的第一中间绝缘区A1，其在对角线下方构成并且在所述第一中间绝缘区A1中在前面进行的制备步骤中在卷绕第一盘1时已经安置绝缘体以及 
·分成带有倒三角形截面的第二中间绝缘区A2，其在对角线上方构成并且在所述第二中间绝缘区A2中在所实施的制备步骤期间与盘2的绕组同时地安置绝缘体，这通过曲折形的线条轮廓画出草图。 
类似的制备措施适用于在实施的制备步骤期间被卷绕的盘2和在下一个制备步骤中待卷绕的盘3之间的中间绝缘体B，因为所述中间绝缘体B的截面以同样的方式被几乎与中间绝缘体B的对角线相应的连接导体7B分成两个分区，也就是 
·分成带有三角形截面的第一中间绝缘区B1，其在该对角线下方构成并且在所述第一中间绝缘区B1中在所实施的制备步骤期间与盘2的绕组同时地安置绝缘体，这通过曲折形的线条轮廓画出草图，以及 
·分成带有倒三角形截面的第二中间绝缘区B2，其在对角线上方构成并且在所述第二中间绝缘区B2中在下一个制备步骤中在卷绕下一个盘3时才安置绝缘体。 
综合来看，因此，本发明规定，盘的绕组与在盘的两侧所需的中间绝缘体的两个分区一起制造，为此，在卷绕导体带5和线匝绝缘体6 期间所述绝缘体同时地以倒三角形截面在一(例如左)侧和三角形截面在另一(例如右)侧安置在盘旁边。 
该绝缘体例如能够由一种或多种玻璃纤维纱组成，所述玻璃纤维纱利用树脂浸渍。对此替代地，也能够使用预先浸渍的材料。特别是在湿浸渍法中，导体带5和线匝绝缘体6之间的中间空间利用树脂填充也是可能的。 
在图2中示出了制成的盘式绕组9(从左往右推进的盘式绕组)的分区的侧视图，所述盘式绕组9由以下组成 
·第一盘1，其由以所期望的线匝数目的导体带5和线匝绝缘体6构成； 
·第二盘2，其由以所期望的线匝数目的导体带5和线匝绝缘体6构成； 
·在盘1和2之间的第一中间绝缘体A，其分成带有三角形截面的第一中间绝缘区A1和带有倒三角形截面的第二中间绝缘区A2，其中所述连接导体7A在两个中间绝缘区A1、A2之间构成对角线界面； 
·第三盘3，其由以所期望的线匝数目的导体带5和线匝绝缘体6构成； 
·在盘2和3之间的第二中间绝缘体B，其分成带有三角形截面的第一中间绝缘区B1和带有倒三角形截面的第二中间绝缘区B2，其中所述连接导体7B在两个中间绝缘区B1、B2之间构成对角线界面； 
·第四盘4，其由以所期望的线匝数目的导体带5和线匝绝缘体6构成； 
·在盘3和4之间的第三中间绝缘体C，其分成带有三角形截面的第一中间绝缘区C1和带有倒三角形截面的第二中间绝缘区C2，其中所述连接导体7C在两个中间绝缘区C1、C2之间构成对角线界面。 
当然，前面的阐述以其整体仅适用于阐述位于两个盘之间的中间绝缘体、在当前情况下的中间绝缘体A、B、C。与此不同地，在第一盘1中省却了带有倒三角形截面(例如在从左往右推进的盘式绕组情 况下盘式绕组的左侧)的中间绝缘区的制备。在最后的盘、这里是盘4中同样也省却了带有三角形截面(例如在从左往右推进的盘式绕组情况下盘式绕组的右侧)的中间绝缘区的制备。 
当然，前面的阐述以其整体也适用于从右往左推进的盘式绕组，如其在图4中画出的草图。
