Abstract

Description
技术领域
本发明涉及一种变压器绕线方法，尤其是一种可防止在次级线圈缠绕过程中发生线圈脱漆而造成短路问题的绕线方法。
背景技术
目前已知的变压器包括有：一绕线轴，一缠绕于前述绕线轴上的线圈，一组配置于前述绕线轴上的铁心，一封装于前述绕线轴与铁心外部的壳体所构成，而在前述缠绕于绕线轴上的线圈可区分为一初级线圈及次级线圈。而前述的初级线圈与次级线圈在缠绕时，先将初级线圈缠绕于初级线轴槽位上，待初级线圈缠绕完成后，在同一线轴上再缠绕次级线圈，因次级电压较高，圈数较多。
另外，在已知变压器中(如图1所示)，在次级线圈线轴上均采用多槽式方式设计，而此设计方式在次级线圈的绕线过程中，同一槽位铜线内会以不规则方式排列，造成铜线间电位差较大，如再加上铜线本身的绝缘不佳(针孔、刮伤...)，比较容易造成短路现象，影响电气输出特性，进而降低变压器的可信度及品质。
发明内容
本发明的主要目的，在于解决上述现有技术的缺陷，避免缺陷存在，本发明利用铜线以积层方式缠绕，缠绕完成的次级线圈，每圈铜线均平整排列，铜线间电位差较小，而每层铜线均包覆一层绝缘薄膜以作隔离，不易形成短路，可确保变压器输出电气特性，并可提高变压器的可信度与品质。
为实现上述目的，本发明于绕线轴的绕线区底层缠绕至少一层以上的初级线圈，在初级线圈缠绕完成后，于初级线圈上包覆一层第一绝缘层，再于第一绝缘层上缠绕多层的次级线圈，而每一层的次级线圈间包覆有第二绝缘层，或绕线轴上具有两绕线区，于任一绕线区缠绕至少一层以上的初级线圈，而在另一绕线区上缠绕多层的次级线圈，而每一层的次级线圈间包覆有第二绝缘层。

具体实施方式
参见图2、3-1所示，为本发明的变压器分解及侧视示意图。如图所示：本发明为一种变压器绕线方法，此绕线方法应用于超小型变压器(Sub-Miniature Tube Transformer)绕线结构上，此变压器至少包括有：一绕线轴1，一组配置于前述绕线轴1上的铁心2，一封装于前述绕线轴1与铁心2外部的壳体3所构成，前述的绕线轴1上具有一供缠绕线圈(图中未示)的绕线区11，此绕线区11两侧具有一相通的接合部12，此接合部12可供接合前述的一组铁心2，在绕线轴1与铁心2组装后，绕线轴1与铁心2外部封装一壳体3，以构成一可输出电能的变压器。
参见图3-2、3-3所示，为图3-1在A-A位置断面剖视及图3-2 的局部放大示意图。如图所示：在绕线轴1的绕线区11上可利用相同或不相同线径的漆包线(包覆有油漆表面的铜线)缠绕于绕线区上，以形成一初级线圈4及次级线圈5。
而此初级线圈4及次级线圈5在缠绕时，先于绕线区11底层缠绕至少一层以上的初级线圈4，而在初级线圈4缠绕完成后，于初级线圈4上包覆一层由绝缘薄膜所形成的第一绝缘层6，此第一绝缘层6完成包覆后，再于第一绝缘层6缠绕多层的次级线圈5，而在每一层的次级线圈5间包覆由绝缘薄膜所形成的第二绝缘层7；前述的次级线圈5的绕线方式，主要是避免铜线在绕线过程中发生脱漆的问题，以避免次级线圈5内的铜线与铜线接触，而形成短路状态，借以提高变压器的电气输出特性及可信度与品质。
参见图4-1所示，为本发明的另一变压器的绕线轴示意图。如图所示：此实施例的绕线轴1’与上述的绕线轴1大致相同，不同之处在于绕线轴1’上具有一相同或不相同大小的绕线区11’、12’，在绕线区11’可缠绕初级线圈(图中未示)，而绕线区12’可供缠绕次级线圈(图中未示)。
参见图4-2、4-3所示，为图4-1在B-B位置断面剖视及图4-2 的局部放大示意图。如图所示：在此绕线轴1’缠绕线圈时，是将至少一层以上的初级线圈4缠绕于绕线区11’位置上，而将至少一层以上的次级线圈5则缠绕于绕线区12’上，在次级线圈5缠绕过程中，在每一层的次级线圈5间包覆由绝缘薄膜所形成的第二绝缘层7，此第二绝缘层7可避免次级线圈5内的铜线与铜线发生脱漆而接触，形成短路状态。同时，利用不同绕线区11’、12’所缠绕的初级线圈4及次级线圈5，可以节省第一绝缘层6的制作及在缠绕线圈上更加省工时、工序，进而可降低制作成本。
可选择地，也可以在绕线轴(1’)上形成两绕线区(11’、12’)，而在每个绕绕区(11’、12’)上分别按照缠绕初级线圈、第一绝缘层以及次级线圈的顺序进行绕线。
进一步，本发明的变压器绕线方法，是利用铜线以积层方式缠绕，缠绕完成的次级线圈，每圈铜线均平整排列，铜线间电位差较小，而每层铜线均包覆一层绝缘薄膜以作隔离，不易形成短路，可确保变压器输出电气特性，并可提高变压器的可信度与品质。
