Abstract

本发明涉及一种绝缘穿刺式线夹，其包括铜铝线夹、连接线夹、穿刺丝杠及过渡绝缘线，过渡绝缘线的两端分别连接有铜铝线夹，铜铝线夹与连接线夹的一侧相连，连接线夹的另一侧为开口侧，穿刺丝杠安装在连接线夹的上、下两面。本发明通过绝缘操作杆的旋转带动穿刺丝杠旋转，便能快速穿过铜铝排绝缘层，可随时更换绝缘导线；保证了线路不停电的情况下即可悬挂接地线，减少停电，提高经济效益。

Description

绝缘穿刺式线夹
技术领域
本发明属于电力输变电技术领域，涉及一种绝缘穿刺式线夹，适用于接点过热时悬挂接地线。
背景技术
东北地区温差大，铜铝的膨胀系数又很高，因此经常造成螺栓松动，螺栓在松动的状态下，长时间运行会造成接点过热放电碳化，铜铝排碳化严重如果不及时处理就会造成爆炸事故发生，为了预防事故的发生，在电力系统运行与检修过程中，经常需要作业人员在接点过热的情况下悬挂接地线，变压器出线绝缘排没有专用的接地端，为了避免过热无法操作，所以经常需要停电悬挂接地线。
发明内容
本发明针对上述现有技术中存在的问题，提供了一种绝缘穿刺式线夹，解决了现有技术中接点过热需要停电悬挂接地线的问题。
本发明的技术方案如下：
包括铜铝线夹、连接线夹、穿刺丝杠及过渡绝缘线，过渡绝缘线的两端分别连接有铜铝线夹，铜铝线夹与连接线夹的一侧相连，连接线夹的另一侧为开口侧，穿刺丝杠安装在连接线夹的上、下两面。
所述的连接线夹的形状为直角U形。
所述的穿刺丝杠的一端设有连接环，穿刺丝杠的另一端设有穿刺丝杠尖，穿刺丝杠尖设置在连接线夹的内部。
所述的连接线夹的上端面设有6个穿刺丝杠，连接线夹的下端面设有1个穿刺丝杠。
所述的铜铝线夹通过螺栓与连接线夹相连。
本发明的优点效果如下：
在U型连接线夹上加装针式穿刺丝杠，通过绝缘操作杆的旋转带动穿刺丝杠旋转，便能快速穿过铜铝排绝缘层，可随时更换绝缘导线；保证了线路不停电的情况下即可悬挂接地线，减少停电，提高经济效益。
附图说明
图1为本发明的结构示意图。
图2为图1的侧面结构示意图。
图中，1、铜铝线夹，2、连接线夹，3、穿刺丝杠，4、连接环，5、穿刺丝杠尖，6、过渡绝缘线，7、螺孔。
具体实施方式
实施例
如图1-2所示，包括铜铝线夹1、直角U形连接线夹2、穿刺丝杠3及过渡绝缘线6，过渡绝缘线6的两端分别连接有铜铝线夹1，铜铝线夹1与连接线夹的一侧通过螺栓螺孔7相连，连接线夹的另一侧为开口侧，穿刺丝杠安装在连接线夹的上、下两面。所述的穿刺丝杠的一端设有连接环4，穿刺丝杠的另一端设有穿刺丝杠尖5，穿刺丝杠尖设置在连接线夹的内部。所述的连接线夹的上端面设有6个穿刺丝杠，连接线夹的下端面设有1个穿刺丝杠。
使用时，用绝缘操作杆锁住穿刺丝杠的连接环，利用绝缘操作杆举起线夹放在线路上待连接的铜鋁排一平位置，将铜铝排对准直角U形连接线夹的开口侧，待铜鋁排全部进入连接线夹后，紧固操作杆，等上下穿刺丝杠扎入铜鋁排绝缘层后，拆下绝缘操作杆。
