Description

一种用于10kV线路变压器的自适应铜铝过渡线夹装置
技术领域
本发明涉及一种变压器线夹，尤其涉及一种用于10kV线路变压器的自适应铜铝过渡线夹装置，属于输电线路设备技术领域。
背景技术
目前10kV线路变压器低压桩头采用设备线夹铜铝过渡，由于铜和铝的热膨胀系数不一致，所以导致线夹过流发热时，铜铝过渡处容易发生断裂、烧化等现象，将导致缺相，从而引起相应地区大面积停电，造成不必要的损失。
发明内容
本发明要解决的技术问题是：提供一种用于10kV线路变压器的自适应铜铝过渡线夹装置，该线夹设计能适应任何配电变压器桩头，且当线夹过流发热时，由于铜和铝的热膨胀系数不一致，铜与铝过渡处会接触更加紧密，减少接触电阻，使线夹不易发生断裂，有效的解决了上述存在的问题。
本发明的技术方案为：一种用于10kV线路变压器的自适应铜铝过渡线夹装置，它包括槽块和楔块，所述槽块为方形结构，在槽块的中间设有圆柱形线孔一，在线孔一的侧边有连通的U形槽孔，楔块为方形结构，楔块中间有通孔且通孔内垫有筒垫，筒垫的中间有线孔二，在楔块的侧壁上固定连接有卡座，卡座上设有方孔，卡座伸入U形槽孔内通过螺栓与槽块连接，螺栓位于方孔内。
所述槽块的侧壁上设有螺孔，螺孔内有锁紧螺钉一，卡座通过锁紧螺钉一在U形槽孔内进行锁紧。
所述楔块的侧壁上设有锁紧螺钉二，所述锁紧螺钉二穿过筒垫伸入线孔二内对导线进行锁紧。
所述卡座与线孔一的相对面为弧形面，弧形面上设有螺纹，与弧形面相对的卡座侧壁上设有凹槽，锁紧螺钉一的端部位于凹槽内进行卡紧。
所述筒垫和锁紧螺钉二的材料为铝，其余材料均为铜。
本发明的有益效果是：与现有技术相比，采用本发明的技术方案，该线夹设计能适应任何配电变压器桩头，且当线夹过流发热时，由于铜和铝的热膨胀系数不一致，铜与铝过渡处会接触更加紧密，减少接触电阻，使线夹不易发生断裂，该线夹槽块和楔块契合时，由槽块侧面铜螺栓固定，由槽块下底面铜螺钉推进，使U形槽孔内的变压器桩头能契合牢固，楔块上部由两铝螺钉固定穿过通孔的铝导线。铝导线位于铝材的筒垫内，发热时由于铝的热膨胀系数要比铜大，所以筒垫会胀大更进一步的卡紧在楔块内，而不会产生断裂、烧化等现象了，取得了很好的使用效果。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将参照本说明书附图对本发明作进一步的详细描述。
实施例1：如附图1～6所示，一种用于10kV线路变压器的自适应铜铝过渡线夹装置，它包括槽块2和楔块4，所述槽块2为方形结构，在槽块2的中间设有圆柱形线孔一1，在线孔一1的侧边有连通的U形槽孔9，楔块4为方形结构，楔块4中间有通孔且通孔内垫有筒垫6，筒垫6的中间有线孔二11，在楔块4的侧壁上固定连接有卡座10，卡座10上设有方孔12，卡座10伸入U形槽孔9内通过螺栓3与槽块2连接，螺栓3位于方孔12内。
进一步的，槽块2的侧壁上设有螺孔8，螺孔8内有锁紧螺钉一7，卡座10通过锁紧螺钉一7）在U形槽孔9内进行锁紧。
进一步的，楔块4的侧壁上设有锁紧螺钉二5，所述锁紧螺钉二5穿过筒垫6伸入线孔二11内对导线进行锁紧。
进一步的，卡座10与线孔一1的相对面为弧形面13，弧形面13上设有螺纹，与弧形面13相对的卡座10侧壁上设有凹槽14，锁紧螺钉一7的端部位于凹槽14内进行卡紧。变压器桩头通过弧形面13上的螺纹与卡座10相互配合，再用锁紧螺钉一7进行锁紧，保证了连接可靠。
进一步的，筒垫6和锁紧螺钉二5的材料为铝，其余材料均为铜。
该线夹设计能适应任何配电变压器桩头，且当线夹过流发热时，由于铜和铝的热膨胀系数不一致，铜与铝过渡处会接触更加紧密，减少接触电阻，使线夹不易发生断裂，该线夹槽块和楔块契合时，由槽块侧面铜螺栓固定，由槽块下底面铜螺钉推进，使U形槽孔内的变压器桩头能契合牢固，楔块上部由两铝螺钉固定穿过通孔的铝导线。铝导线位于铝材的筒垫内，发热时由于铝的热膨胀系数要比铜大，所以筒垫会胀大更进一步的卡紧在楔块内，而不会产生断裂、烧化等现象了，取得了很好的使用效果。
本发明未详述之处，均为本技术领域技术人员的公知技术。最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
