技术领域
本发明涉及一种铜与铝合金配合使用方法适用于各种电压等级 的电线电缆、 母线、 变压器、 开关、 套管的导体中使用。 背景技术
现有的电线电缆、 母线行业为了提高载流量、 降成本， 提出了高 强度铜包铝电缆导体、 扩径钢芯铝绞线、 空心电缆、 高压空心电缆、 组合导体结构电力电缆、 多分裂铜或铝母线。但还是没找到一个更有 效果降成本、提高载流量的办法。上述系列产品的导体采用是铜、铝、 铜包铝、 铜铝之间有绝缘隔离的导体， 其缺点：
①铜载流量小， 温升高， 成本高。
②铝载流量小， 温升高， 铝导电率与铜比相对较差及易氧化。
③铜包铝载流量小， 温升高， 铜包铝工艺复杂， 是冶金结合（现有技 术铜与铝的配合使用必须是冶金结合， 不然有电化学反应）， 铜铝 的粘合性是铜与铝不分层， 是一个整体， 电流密度分布不均匀。等 径的铜线与铜包铝线相比， 铜线比铜包铝线载流量大， 等径的铜包 铝电缆与铜电缆相比不节能， 并且废旧铜包铝电线电缆在回收中， 铜铝分离工艺复杂， 污染严重。
④多分裂铜或铝母线的缺点： 载流量小， 温升高， 铜铝之间有绝缘隔 离，铜铝电化学反应解决了，但铜、铝是两个独立导体，不等电位， 两个导体间的电磁场相互干扰， 相互降低载流量。 发明内容
本发明的目的是克服现有技术的缺点，提出保留铜与铝合金的本 体氧化层（氧化层很薄， 电阻很小）作为隔离保护层， 防止电化学反 应， 铜与铝合金（如铝镁合金、 稀土铝合金）配合是搭接结合， 通过 隔离保护层的分裂，铜、铝合金形成两个相对独立但电位相等的导体， 相互之间不会产生电磁干扰， 电流密度分布均匀效果大大提高。
实现本发明目的的技术方案：本发明一种铜与铝合金配合使用方 法是用于：①圆形导体采用外层导体是铜、内层导体是铝合金，用铜、 铝合金的本体氧化层作为隔离保护层， 导体结构有铜套铝合金棒（大 直径为棒， 直径小于 5mm为线）、 铜套铝合金管、 铜绞铝合金线、 扩 径铜绞铝合金绞线、铜绞钢芯铝合金绞线、扩径铜绞钢芯铝合金绞线； ②矩形导体外面是铜， 铝合金带（排）在中间， 用铜、 铝合金带（排) 的本体氧化层作为隔离层。上述导体根据电压等级需要可在导体上外 加绝缘层或屏蔽绝缘层。
本发明的有益效果是：一种铜与铝合金配合使用方法是用铜与铝 合金的本体氧化层作为隔离保护层， 铜与铝合金配合是搭接结合， 电 流密度分布均匀效果比铜、 铝、 铜包铝 （铜铝冶金结合）、 铜铝之间 有绝缘隔离的导体要好。①等径的铜线与铜套铝合金线相比， 铜套铝 合金线载流量大， 温升低； ②等径的铜棒与铜套铝合金棒相比， 铜套 铝合金棒载流量大， 温升低； ③等径、 等截面的铜管与铜套铝合金管 相比， 铜套铝合金管载流量大， 温升低； ④等径的铜绞线与铜绞铝合 金线相比， 铜绞铝合金线载流量大， 温升低。一种铜与铝合金配合使 用方法所形成的导体比铜、 铝、 铜包铝、 铜铝之间有绝缘隔离的导体 载流量大， 温升低。金属氧化层做隔离保护层的应用实现了提高载流 量、 温升低、 降成本的节能效果。
