Description
一种铜绍设备线夹
技术领域
[0001 ] 本实用新型涉及一种铜铝设备线夹。
背景技术
[0002] 在电力系统中，导线与电气设备端子相连接时通常采用设备线夹，用以传递电气负荷。目前，铜、铝是电力输送过程中的主要材料，由于铝质轻、价格低廉、导电性能好，一般用作基质，铜较重而且价格高，但稳定性好、导电性能好，不容易被腐蚀，一般用于接触部位。铜铝连接会产生电化学反应，增大接触电阻，烧毁线夹，因此现有的设备线夹通常采用铜铝过渡设备线夹，这种设备线夹通常是一端为铜质材质，另一端为铝质材质，铜铝之间通过两种材质的狭小截面摩擦焊接或闪光焊接的方式对接。铜铝的这种连接方式导致线夹存在致命的弱点：首先是对焊接工艺要求极高，很容易在铜铝的接触处发生断裂，造成电网故障或更大的事故；而且铜材使用较多，成本较高。
实用新型内容
[0003] 本实用新型提出一种铜铝设备线夹，能很好地解决铜铝通过端面对接方式闪光焊或摩擦焊的设备线夹容易断裂的问题，而且减少了铜的用量，大大节约了成本，弥补了现有技术中的不足之处。
[0004] 本实用新型的技术方案是这样实现的：
[0005] 一种铜铝设备线夹，包括铝主体和铜板，所述铝主体包括一体的铝质压接管和铝排，所述铜板通过钎焊覆盖在所述铝排的下表面，所述铜板和所述铝排上设有相互对应的安装孔。
[0006] 所述铝质压接管和所述铝排之间成30°角弯折过渡状一体连接。
[0007] 所述安装孔为四个。
[0008] 所述铜板和所述铝排的尺寸相一致。
[0009] 所述铝质压接管的远离所述铝排的一端的管腔内插接支撑杆。
[0010] 本实用新型的有益效果为：在铜和铝之间采用钎焊平面接触的方式能很好地解决铜铝通过端面对接方式闪光焊或摩擦焊的设备线夹容易断裂的问题；设备线夹出线角度由原来的180°改进为30°，大大改善了导线的受力情况；仅仅覆盖一层铜板层，可以大大减少铜的用量，节约了成本；综上所述本实用新型有效消除了设备线夹裂纹的重大缺陷，彻底避免因设备线夹裂纹缺陷发展至断裂故障，造成高压引线脱落接地事故的发生，提高了设备的安全可靠运行，避免了重大经济损失。
附图说明
[0011] 为了更清楚地说明本实用新型实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本实用新型的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
[0012] 图I为本实用新型实施例所述的铜铝设备线夹的后视图；
[0013] 图2为本实用新型实施例所述的铜铝设备线夹的侧视图；
[0014] 图3是铜铝对接闪光焊型设备线夹的主视图；
[0015] 图4是铜铝对接闪光焊型设备线夹的侧视图。
[0016]图中：
[0017] I、铜板；2、铝质压接管；3、铝排；4、安装孔；5、铜铝接触面。
具体实施方式
[0018] 下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
[0019] 如图1-2所示，本实用新型实施例所述的铜铝设备线夹，包括铝主体和铜板1，所述铝主体包括一体的铝质压接管2和铝排3，所述铜板I通过钎焊覆盖在所述铝排3的下表面，所述铜板I和所述铝排3上设有相互对应的安装孔4。
[0020] 所述铝质压接管2和所述铝排3之间成30°角弯折过渡状一体连接。
[0021] 所述安装孔4为四个。
[0022] 所述铜板I和所述铝排3的尺寸相一致。
[0023] 所述铝质压接管2的远离所述铝排3的一端的管腔内插接支撑杆。
[0024] 其中，在铜和铝之间采用钎焊平面接触的方式连接可以增加铝铜的接触面积，降低电阻，铜铝接触面紧密、可靠，水及空气都无法进入铜铝接合面，二者不易出现氧化现象，能很好地解决铜铝通过端面对接方式闪光焊或摩擦焊的设备线夹容易断裂的问题；设备线夹出线角度由原来的180°改进为30°，大大改善了导线的受力情况；仅仅覆盖一层铜板层，可以大大减少铜的用量，节约了成本；综上所述本实用新型有效消除了设备线夹裂纹的重大缺陷，彻底避免因设备线夹裂纹缺陷发展至断裂故障，造成高压引线脱落接地事故的发生，提高了设备的安全可靠运行，避免了重大经济损失。
[0025] 如图3-4为铜铝对接闪光焊型设备线夹，由于铜铝接触面5的面积狭小，很容易在铜铝接触处断裂。
[0026] 以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
