Abstract

本实用新型螺旋高压接地棒线卡，具有反7形外卡和L形内卡，外卡的纵向卡臂的内壁与内卡的纵向卡臂的外壁连接，L形内卡的横向卡臂上设有螺纹孔，它穿接有一螺纹调节杆，螺纹调节杆的顶端安有顶板，螺纹调节杆的底端连有棒杆，反7形外卡纵向卡臂的内壁上开有调节孔，L形内卡的纵向卡臂上设有螺杆，螺杆穿过调节孔通过螺母与反7形外卡连接；所述调节孔的纵向长度10-15cm之间；本实用新型结构简单，使用方便，协助人员少，能有效增大或缩小线卡卡口的开口距离，满足不同规格变电站低压母线桥接地需求。

Description

螺旋高压接地棒线卡
㈠技术领域：本实用新型涉及电力企业工具，具体是螺旋高压接地棒线卡。
㈡背景技术：目前，传统的固定式螺旋接地棒线卡由于外卡和内卡为固定连接，线卡卡口的开口距离调节有限，不能满足不同规格变电站低压母线桥接地，在使用时不是很方便，协助人员多，工作效率不高。
㈢发明内容：本实用新型的目的就是对以上缺点进行改进。提出一种结构简单，使用方便，能有效增大线卡卡口的开口距离的螺旋高压接地棒线卡。 
本实用新型螺旋高压接地棒线卡，具有反7形外卡和L形内卡，外卡的纵向卡臂内壁与内卡的纵向卡臂外壁连接，L形内卡的横向卡臂上设有螺纹孔，它穿接有一螺纹调节杆，螺纹调节杆的顶端安有顶板，螺纹调节杆的底端连有棒杆，其特征在于：反7形外卡卡臂的内壁上开有调节孔，L形内卡的纵向卡臂外壁设有螺杆，螺杆穿过调节孔通过螺母与反7形外卡连接。
所述螺旋高压接地棒线卡，其特征在于：所述调节孔的纵向长度在10-15cm之间。
本实用新型结构简单，使用方便，协助人员少，能有效增大或缩小线卡卡口的开口距离，满足不同规格变电站低压母线桥接地需求。
㈣附图说明
图1是本实用新型整体结构示意图；
图2是反7形外卡结构示意图。
图中，1-反7形外卡，2-L形内卡，3-螺纹调节杆，4-顶板，5-棒杆，6-调节孔，7-螺杆，8-螺母，9-螺纹孔。
㈤具体实施方式：
参见图1，图2，本实用新型螺旋高压接地棒线卡的具体方案是：具有反7形外卡1和L形内卡2，外卡的纵向卡臂内壁与内卡纵向卡臂外壁连接，L形内卡的横向卡臂上设有螺纹孔9，它穿接有一螺纹调节杆3，螺纹调节杆的顶端安有顶板4，螺纹调节杆的底端连接有棒杆5，反7形外卡的纵向卡臂内壁开有调节孔6，调节孔6的纵向长度在10-15cm之间；L形内卡的纵向卡臂外壁上设有螺杆7，螺杆穿过调节孔6通过螺母8与反7形外卡连接。使用时，先根据不同规格变电站低压母线桥接地需求，松开侧部螺母，将内卡调节到适当位置，紧固螺母固定内卡，然后通过旋转棒杆来微调压板，这样卡口的开口度就能满足不同规格变电占低压母线桥接地需求。
