Description

变压器线圈
技术领域
本实用新型涉及变压器技术领域,具体讲是一种变压器线圈。
背景技术
变压器线圈是变压器的心脏,是变压器的重要部件。变压器突然短路事故是造成变压器损坏的主要原因,当发生突然短路时,变压器绕组受到极大地电磁力作用,使绕组变形,从而使变压器无法正常使用。
实用新型内容
本实用新型要解决的技术问题是,提供一种抗短路能力强、防止发生扭曲变形的变压器线圈。
本实用新型的技术方案是,提供具有以下结构的变压器线圈,包括绕制在低压线圈外周的高压线圈,其特征在于:所述高压线圈外壁设有多根固定的环形绝缘绑带,所述多根环形绝缘绑带沿高压线圈的轴线等分高压线圈。
所述环形绝缘绑带内部嵌有加强线。
所述环形绝缘绑带的内壁设有若干条径向的环形凹槽。
采用上述结构后,本实用新型与现有技术相比,具有以下优点:由于在高压线圈外壁增加了多根环形绝缘绑带,这样使线圈机械强度高;能更好地防止突发短路事故,避免线圈绕组受电磁力作用,幅向发生扭曲变形,增强变压器抗短路能力。
作为改进,所述环形绝缘绑带内部嵌有加强线,增加环形绝缘绑带的强度和韧性。
作为改进,所述环形绝缘绑带的内壁设有若干条径向的环形凹槽,增加与线圈外壁的贴合力,防止在意外状况下脱落。
附图说明
附图1是本实用新型的变压器线圈的结构示意图。
附图2是本实用新型的变压器线圈的环形绝缘绑带剖面示意图。
图中所示,1、低压线圈,2、高压线圈,3、环形绝缘绑带,3.1、环形凹槽,4、加强线。
具体实施方式
下面结合附图对本实用新型变压器线圈打包做进一步说明。
如图1和图2所示,本实用新型的变压器线圈,包括绕制在低压线圈1外周的高压线圈2,所述高压线圈2外壁设有多根固定的环形绝缘绑带3,所述多根环形绝缘绑带3沿高压线圈2的轴线等分高压线圈2。由于在高压线圈外壁增加了多根环形绝缘绑带,这样使线圈机械强度高;能更好地防止突发短路事故,避免线圈绕组受电磁力作用,幅向发生扭曲变形,增强变压器抗短路能力。
所述环形绝缘绑带3内部嵌有加强线4,增加环形绝缘绑带的强度和韧性。
所述环形绝缘绑带3的内壁设有若干条径向的环形凹槽3.1,增加与线圈外壁的贴合力,防止在意外状况下脱落。
