Description

BJL2型特高压空芯电抗器用压方绝缘铝绞线
技术领域
本发明涉及特高压空芯电抗器用导线制造技术领域。
背景技术
现有技术中电抗器采用普通圆铝线包覆绝缘层后进行单根绕制，线间承受5000伏以下电压值，不能满足特高压输变电要求。
普通铝线多根绕制时，由于股间绕制产生的不等长影响线间的电阻平衡，从而导致涡流损耗过大，不仅导致能源的浪费，而且由于发热温升带来较大的安全隐患。
普通铝线多根绕制时，圆铝线之间的间隙较大，导致绕制成的电抗器体积较大，不方便安装和使用，同时浪费现象较严重。
发明内容
本发明目的在于针对以上问题，提供一种能承受超高压、增强电阻平衡、体积小、绕制方便的BJL2型特高压空芯电抗器用压方绝缘铝绞线。
本发明包括由多根相同规格铝圆导线绞合压方而成的矩形线芯，在所述多根矩形线芯外侧顺时针包覆第一聚酯薄膜层和第二聚酯薄膜层，在所述第二聚酯薄膜层外侧逆时针包覆无纺布层。
本发明结构简单合理，工作时噪音小，温升慢、体积小、方便绕制，节约人力，提高工作效率。
附图说明
图1为本发明的结构示意图。
具体实施方式
如图1所示，本发明包括由多根相同规格铝圆导线1绞合压方而成的矩形线芯2，在多根矩形线芯2外侧顺时针包覆第一聚酯薄膜层3和第二聚酯薄膜层4，在第二聚酯薄膜层4外侧逆时针包覆无纺布层5。
