Description

一种环形电感绕线方法及其电感
技术领域
本发明涉及电器元件制备技术领域，具体是一种环形电感绕线方法及其电感。
背景技术
电感器(Inductor)是能够把电能转化为磁能而存储起来的元件，其一般由骨架、绕组、屏蔽罩、封装材料、磁心或铁心等组成。绕组是指具有规定功能的一组线圈，它是电感器的基本组成部分。
环形共模电感即是采用在磁环上绕制绕组，其绕组缠绕在磁环上呈环形分布。目前，环形（共模）电感绕组的绕制一般是采用两根绝缘线并排按次序绕制，两根绝缘线在磁环上交错排布，但是这种绕制方式很多情况下受尺寸限制不能延磁环一周内均匀的将全部圈数布线完成，这样磁动势不能均匀分布在磁环上，会产生较大的漏磁导致耦合性变差，漏感大。
发明内容
本发明的目的在于提供一种环形电感绕线方法及其电感，采用该方法绕制得到的电感能够保证两根绝缘线的绕线圈数完全相同，使磁动势均匀分布在磁环上，有效减少漏磁，且能满足高耐压的要求。
本发明解决其技术问题所采用的技术方案是：
一种环形电感绕线方法，所述方法采用两根不同颜色的绝缘线，第一绝缘线与第二绝缘线并排在磁环上顺时针绕制，起始绕制时第一绝缘线在左侧、第二绝缘线在右侧；
当绕制到第n圈时，第一绝缘线沿着已绕制的最右侧绝缘线的左侧绕制，第二绝缘线沿着已绕制的最右侧绝缘线的右侧绕制，直至在磁环上绕制完毕，n≥2。
本发明另一目的是提供一种环形电感，所述电感的绕组采用上述绕线方法制得。
本发明的有益效果是，采用本方法绕制得到的绕组，两根绝缘线的绕线圈数完全相同，能够使磁动势均匀分布在磁环上，绕组间耦合性好，可以有效减少漏磁，且能满足高耐压的要求。
附图说明
下面结合附图和实施例对本发明进一步说明：
图1是本发明方法绕制得到的绕组示意图；
图2是本发明方法绕制前四圈的绝缘线分布示意图；
图3是本发明得到的绕组磁路示意图；
图4是本发明得到的绕组磁动势与磁阻分布示意图；
图5是本发明得到的绕组磁路等效示意图。
具体实施方式
如图1所示，本发明提供一种环形电感绕线，所述方法采用两根不同颜色的绝缘线，本实施例采用红色与黄色，第一绝缘线A为红色，第二绝缘线B为黄色，第一绝缘线A与第二绝缘线B并排在磁环C上顺时针绕制；结合图2所示，图2中数字表示绕制的圈数，A1、B1表示第1圈的第一绝缘线与第二绝缘线，A2、B2表示第2圈的第一绝缘线与第二绝缘线，A3、B3表示第3圈的第一绝缘线与第二绝缘线，A4、B4表示第4圈的第一绝缘线与第二绝缘线；起始绕制时，也即是第1圈，第一绝缘线在左侧、第二绝缘线在右侧；
当绕制到第n圈时，第一绝缘线沿着已绕制的最右侧绝缘线的左侧绕制，第二绝缘线沿着已绕制的最右侧绝缘线的右侧绕制，直至在磁环上绕制完毕，n≥2。
本发明另一目的是提供一种环形电感，所述电感的绕组采用上述绕线方法制得。
本发明方法不仅可以用于两相绕组的绕制，还可以用于三相、四相绕组的绕制。
结合图3～5所示，由于本方法是将绝缘线均匀绕制在磁环上，这样磁路系统完全对称，即等截面均匀绕线的环形磁芯任意点间没有磁位差，即等磁位，在环外不会有任何散磁通，磁力线局限于导磁体内，漏磁可以做到最小。另外两绕组采用并绕，两个绕组间的间距最小，耦合度最好，漏感最小（小于0.3%）。
根据磁路欧姆定律磁动势 ，F=NI=Hl=ΦRm ,Fx为磁动势,Ux为x=0这一点的磁位差，Ucx为磁环其它相对位置的磁位差, Fx=Ucx+Ux, 可以看出Fx和Ucx变化趋势是一致的。也就是说，将图形Fx减去Ucx图形，就得到Ux分布情况。显然，Ux处处为零。即等截面均匀绕线的环形磁芯任意点间没有磁位差，即等磁位在环外不会有任何散磁通，磁力线局限于导磁体内。
以上所述，仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制；任何熟悉本领域的技术人员，在不脱离本发明技术方案范围情况下，都可利用上述揭示的方法和技术内容对本发明技术方案做出许多可能的变动和修饰，或修改为等同变化的等效实施例。因此，凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所做的任何简单修改、等同替换、等效变化及修饰，均仍属于本发明技术方案保护的范围内。
