Description

一种太阳能发电用分裂式绕组结构
技术领域
本发明涉及一种分裂式绕组结构，尤其涉及一种太阳能发电用分裂式绕组结构。
技术背景
近年来我国可再生能源的发展比较迅速，包括风电、太阳能发电。由于太阳能发电逆变器目前容量为630kW，每个逆变器需配一个升压变压器，尤其是35kV侧高压电缆及相应高压设备投资费用大大增加，目前现有的分裂式绕组结构有轴向分裂和辐向分裂，轴向分裂在其中一个初级绕组短路的情况下，由于初、次级绕组间安匝的极度不平衡，极易造成绕组损坏。而辐向分裂结构制造费用将大大增加，且次级绕组分别对应的两初级绕组的短路阻抗相差很大。因此这两种结构均不十分适用，这一问题已经成为投资费用大大增加的重要因素。
发明内容
本发明克服了现有技术中的不足，提供一种太阳能发电用分裂式绕组结构，实现了初、次级绕组间安匝的平衡，防止了绕组损坏，减少了投资费用，降低了损耗。
本发明通过下述技术方案予以实现：
一种太阳能发电用分裂式绕组结构，包括第一初级绕组、第二初级绕组和次级绕组，所述的次级绕组绕于最外层，第一初级绕组与第二初级绕组位于内层且相互起绕至结束错开180度绕制。
所述的一种太阳能发电用分裂式绕组结构，其中第一初级绕组和第二初级绕组的电阻值与所述的次级绕组的阻抗相等。
所述的一种太阳能发电用分裂式绕组结构，其中第一初级绕组、第二初级绕组材质为铜箔或铝箔。
所述的一种太阳能发电用分裂式绕组结构，其中分裂式绕组结构为方形或圆形或椭圆形，其形状根据变压器铁心而定。
由于采用上述技术方案，本发明提供的一种太阳能发电用分裂式绕组结构具有这样的有益效果：实现了初、次级绕组间安匝的平衡，防止了绕组损坏，减少了投资费用，降低了损耗。
附图说明
图1是本发明的一种太阳能发电用分裂式绕组结构的结构示意图。
具体实施方式
下面通过具体实施方式对本发明作进一步详细描述。
请参阅图1，图中示出了本发明的一种太阳能发电用分裂式绕组结构，包括第一初级绕组1、第二初级绕组2和次级绕组3，次级绕组3绕于最外层，第一初级绕组1与第二初级绕组2位于内层且相互起绕至结束错开180度绕制，材质为铜箔或铝箔，电阻值与次级绕组3的阻抗相等。同时，该太阳能发电用分裂式绕组结构为方形或圆形或椭圆形，其形状根据变压器铁心而定。
新的解决方案两个逆变器送至一个有两个初级绕组的分裂式变压器。这样大大缩小了高压侧的投资费用，也减少了变压器的投资费用，同时降低了总的变压器的损耗。目前现有的分裂式绕组结构有轴向分裂和辐向分裂，轴向分裂在其中一个初级绕组短路的情况下，由于初、次级绕组间安匝的极度不平衡，极易造成绕组损坏。而辐向分裂结构制造费用将大大增加，且次级绕组分别对应的两初级绕组的短路阻抗相差很大。新的方案解决了上述问题。
以上实施方式对本发明进行了详细说明，本领域中普通技术人员可根据上述说明对本发明做出种种变化例。因而，实施方式中的某些细节不应构成对本发明的限定，本发明将以所附权利要求书界定的范围作为本发明的保护范围。
