Description

卷铁心变压器线圈绕制结构 技术领域
本发明涉及电力设备领域，特别涉及一种卷铁心变压器线圈绕制结构。
背景技术
随着电力系统发展，人们越来越注重节能环保型产品的研发使用，由于卷铁心变压器具有三相平衡、空载损耗低、空载电流低、噪声低和成本低等优点，因此越来越受青睐。卷铁心配电变压器在很多时候都需要使用箔式线圈，而这种线圈一般采用卧绕的方法来进行绕制。但是，这种方法需要安装夹持铁心的夹具，使得绕线设备复杂、操作相对耗时。而且，对于箔式线圈来说，箔的平整度是非常重要的，如铜箔有划痕或损伤部位，卷绕时则容易损伤箔间的绝缘，从而降低变压器的可靠性。但是，卧绕线圈时，往往难以观察到铜箔向下一面的情况，使得操作者无法完全把控操作质量。此外，在绕制过程中，由于铁心的心柱受力，容易导致空载损耗变化；并且，在绕制完成后，需要对铁心进行翻转，而在翻转过程中，线圈容易发生移位导致线圈损坏。
发明内容
本发明旨在至少解决现有技术中存在的技术问题之一。为此，本发明提出一种卷铁心变压器线圈绕制结构，能够简化铁心的绕线设备，并降低因绕线而造成铁心损耗变化的机率，从而优化卷铁心的线圈绕制效果。
本发明实施例提供了一种卷铁心变压器线圈绕制结构,应用于卷铁心变压器，所述卷铁心变压器线圈绕制结构包括：铁心，所述铁心包括若干个心柱；绕线模具，所述绕线模具为中空结构，所述绕线模具套置在所述心柱上，所述绕线模具包括上部模具、中部模具和下部模具，所述中部模具的两端分别连接所述上部模具和所述下部模具，所述上部模具包括第一固定部件和第一旋转部件，所述下部模具包括第二固定部件和第二旋转部件，所述第一固定 部件与所述第一旋转部件连接，所述第二固定部件与所述第二旋转部件连接，所述第一固定部件和所述第二固定部件用于将所述绕线模具套设在所述心柱上，所述第一旋转部件和所述第二旋转部件用于带动所述中部模具转动；线圈，所述线圈为箔式线圈，所述线圈卷绕在所述中部模具上。
根据本发明实施例的卷铁心变压器线圈绕制结构，至少具有如下有益效果：工作时，将绕线模具套置在卷铁心的心柱上，并通过上部模具的第一固定部件和下部模具的第二固定部件将绕线模具与心柱固定，并使线圈在第一旋转部件、第二旋转部件和中部模具的转动下卷绕在中部模具上。通过在卷铁心变压器的线圈绕制过程中应用该卷铁心变压器线圈绕制结构，只需要安装绕线模具即可进行绕线，从而避免了传统的卧绕工艺中绕线设备需要安装铁心夹具以对铁心进行夹持的不便，简化了铁心的绕线设备，此外，由于在绕线过程中无需夹持铁心而是采用立绕的绕线方式，使得操作者能够方便地观察到铜箔另一面的情况，从而更好地把控操作质量，而且这种绕线方式，使得心柱在线圈的绕制过程中不受力，从而使得绕线前后铁心的空载损耗较为稳定，并在线圈绕制完成后无需对铁心和线圈进行翻转，从而降低了因绕线而造成铁心损耗变化的机率，优化了卷铁心的线圈绕制效果。

此外，下面所描述的本发明各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
随着电力系统发展，人们越来越注重节能环保型产品的研发使用，由于卷铁心变压器具有三相平衡、空载损耗低、空载电流低、噪声低和成本低等优点，因此越来越受青睐。卷铁心配电变压器在很多时候都需要使用箔式线圈，而这种线圈一般采用卧绕的方法来进行绕制。但是，这种方法需要安装夹持铁心的夹具，使得绕线设备复杂、操作相对耗时。而且，对于箔式线圈来说，箔的平整度是非常重要的，如铜箔有划痕或损伤部位，卷绕时则容易损伤箔间的绝缘，从而降低变压器的可靠性。但是，卧绕线圈时，往往难以观察到铜箔向下一面的情况，使得操作者无法完全把控操作质量。此外，在绕制过程中，由于铁心的心柱受力，容易导致空载损耗变化；并且，在绕制完成后，需要对铁心进行翻转，而在翻转过程中，线圈 容易发生移位导致线圈损坏。
为此，本发明提出一种卷铁心变压器线圈绕制结构及其绕制方法，能够简化铁心的绕线设备，并降低因绕线而造成铁心损耗的机率，从而优化卷铁心的线圈绕制效果。
下面结合附图，对本发明实施例作进一步阐述。
本发明实施例提出一种卷铁心变压器线圈绕制结构,应用于卷铁心变压器，卷铁心变压器线圈绕制结构包括：铁心100，绕线模具200和线圈300。
参照图1至图3，具体地，铁心100包括若干个心柱110；绕线模具200为中空结构，绕线模具200套置在心柱110上，绕线模具200包括上部模具210、中部模具220和下部模具230，中部模具220的两端分别连接上部模具210和下部模具230，上部模具210包括第一固定部件211和第一旋转部件212，下部模具230包括第二固定部件231和第二旋转部件232，第一固定部件211与第一旋转部件212连接，第二固定部件231与第二旋转部件232连接，第一固定部件211和第二固定部件231用于将绕线模具200套设在心柱110上，第一旋转部件212和第二旋转部件232用于带动中部模具220转动；线圈300为箔式线圈，线圈300卷绕在中部模具220上。
工作时，将绕线模具200套置在卷铁心的心柱110上，并通过上部模具210的第一固定部件211和下部模具230的第二固定部件231将绕线模具200套设在心柱110上，并使线圈300在第一旋转部件212、第二旋转部件232和中部模具220的转动下卷绕在中部模具220上。
可以理解的是，通过在卷铁心变压器的线圈300绕制过程中应用该卷铁心变压器线圈绕制结构，只需要安装绕线模具200即可进行绕线，从而避免了传统的卧绕工艺中绕线设备需要安装铁心100夹具以对铁心100进行夹持的不便，简化了铁心100的绕线设备，此外，由于在绕线过程中无需夹持铁心100而是采用立绕的绕线方式，使得操作者能够方便地观察到铜箔另一面的情况，从而更好地把控操作质量，而且这种绕线方式，使得心柱110在线圈300的绕制过程中心柱110不受力，从而使得绕线前后铁心100的空载损耗较为稳定，并在线圈300绕制完成后无需对铁心100和线圈300进行翻转，从而降低了因绕线而造成铁心100损耗变化的机率，优化了卷铁心的线圈300绕制效果。
需要说明的是，参照图1和图3，该卷铁心可以为三相立体卷铁心，也可以为单相卷铁心，本实施例并不对其做限制。
参照图1，示例性的，铁心100为三相立体卷铁心，心柱110的数量为三个。
参照图3，示例性的，铁心100为单相卷铁心，心柱110的数量为两个。
参照图1，示例性的，卷铁心变压器包括上夹件120和下夹件130，第一固定部件211与上夹件120连接，第二固定部件231与下夹件130连接。可以理解的是，将第一固定部件211与上夹件120连接，并将第二固定部件231与下夹件130连接，能够使绕线过程更加稳定。需要说明的是，第一固定部件211与上夹件120的连接方式，第二固定部件231与下夹件130的连接方式，可以为螺纹连接、卡扣连接等，本实施例并不对其做限制。
参照图1和图2，中部模具220为圆筒结构或为若干个可拼合成圆筒的弧形板结构。可以理解的是，圆筒结构可以使线圈300的卷绕更加均匀和快速。
参照图2，第一旋转部件212和第二旋转部件232分别为至少两个可拼接成环状的弧形板结构。可以理解的是，工作时，第一旋转部件212和第二旋转部件232将心柱110套置后再进行拼合固定。
示例性的，上部模具210和/或下部模具230还包括传动轮，传动轮用于带动中部模具220、第一旋转部件212和第二旋转部件232转动。工作时，外部设备驱动传动轮转动，从而带动中部模具220、第一旋转部件212和第二旋转部件232转动。需要说明的是，可以仅在上部模具210或下部模具230设置传动轮，也可以在上部模具210和下部模具230均设置有传动轮，本实施例并不对其做限制。需要说明的是，该传动轮可以为齿轮，也可以为皮带轮，本实施例并不对其种类做限制。需要说明的是，传动轮的数量可以为1个、2个等，本实施例并不对其数量做限制。
参照图4，示例性的，线圈300的出头端设有铜排310，铜排310的一侧设有软连接320。具体地，线圈300的出头方式采用焊接铜排310出头，铜排310一侧连接有软连接320，软连接320用作线圈300出头。
示例性的，线圈300的出头端包括水平部340和弯折部350，水平部340与弯折部350之间的夹角为90度。具体地，如图5B和图5D所示，线圈300为铜箔330制件，线圈300的出头采用折弯出头的方式，将铜箔330起头和首尾端部横向剪切成若干长条，长条之间可以有间隔，剪切完成后使长条向上90度折弯形成出头，使得水平部340与弯折部350之间的夹角呈90度。
需要说明的是，水平部340与弯折部350之间的夹角也可以为45度、60度等，本实施例并不对其做限制。
示例性的，应用该卷铁心变压器线圈绕制结构时，可以参照以下步骤。
首先，将上部模具210和下部模具230套置在心柱110上进行拼装和固定；然后，将中部模具220固定在上部模具210和下部模具230之间，调整中部模具220、第一旋转部件212和第二旋转部件232的位置以使中部模具220可转动；之后，将线圈300的出头固定在中部模具220所在的轴向高度范围内；最后，通过外部设备带动传动轮转动以使线圈300卷绕在中部模具220上。
可以理解的是，应用该卷铁心变压器线圈绕制结构，只需要安装绕线模具200即可进行绕线，从而避免了传统的卧绕工艺中绕线设备需要安装铁心100夹具以对铁心100进行夹持的不便，简化了铁心100的绕线设备，此外，由于在绕线过程中无需夹持铁心100而是采用立绕的绕线方式，因此在线圈300的绕制过程中心柱110不受力，使得绕线前后铁心100的空载损耗较为稳定，并在线圈300绕制完成或无需对铁心100和线圈300进行翻转，从而降低了因绕线而造成铁心100损耗的机率，优化了卷铁心的线圈300绕制效果。
示例性的，卷铁心变压器包括上夹件120和下夹件130，在将上部模具210和下部模具230套置在心柱110上进行拼装和固定之前，还需要将第一固定部件211与上夹件120连接，并将第二固定部件231与下夹件130连接以使绕线模具200套设在心柱110上。
可以理解的是，将第一固定部件211与上夹件120连接，并将第二固定部件231与下夹件130连接，能够使绕线过程更加稳定。需要说明的是，第一固定部件211与上夹件120的连接方式，第二固定部件231与下夹件130的连接方式，可以为螺纹连接、卡扣连接等，本实施例并不对其做限制。

示例性的，参照图5C至图5D，线圈300为铜箔330制件，线圈300的折弯出头方式可以为，在铜箔330的出头沿着绕制方向进行裁剪，将铜箔330的出头剪成若干长条，长条间留存有间隔，使长条向上呈90°角折弯引出，并固定在中部模具220所在的轴向高度内。
