本技术主要涉及高压开关
,特指一种双柱旋转开启式隔离开关的导电底座。
技术介绍
在电力系统中,双柱旋转开启式隔离开关包括双柱水平旋转开启式和双柱V型旋转开启式隔离开关,广泛应用于各35KV及以上电压的变电站,目前,双柱旋转开启式隔离开关的导电底座绝大部分为铸件结构,结构复杂,且铸造成本高,铸件种类多,重量高,散热较差,工作不可靠,阻碍了电力系统长久稳定的运行,且增大了电网在运行和维护中的成本。
技术实现思路
本技术要解决的技术问题是,克服现有双柱旋转开启式隔离开关导电底座的不足,提供一种结构简单、工作可靠的导电底座装置。本技术解决其技术问题采用的技术方案是:一种双柱旋转开启式隔离开关的导电底座,包括接线座和小矩管,小矩管装设于接线座的侧面的外表面,接线座的侧面的内表面与柔性导电带的一端相连,小矩管装于导电杆内部;柔性导电带的另一端与导电轴的下端固连,接线端子安装于导电轴上端,接线端子和导电轴固连。接线座下部设有凸台,接线座上部与凸台均开设有轴孔,导电轴穿过接线座上部的轴孔和凸台的轴孔;接线座上部的轴孔内、凸台的轴孔内均装有设于导电轴外周的绝缘轴套。进一步,接线座、小矩管和柔性导电带三者的接触面均开设有螺栓安装孔,三者通过穿过螺栓安装孔的螺栓贯穿相连。进一步,小矩管的前端面和后端面均开有螺杆安装孔,小矩管装于导电杆内部,小矩管通过穿过螺杆安装孔的螺杆与导电杆贯穿相连。进一步,接线座的纵向截面为“口”字形结构,以利于增强其散热性能和降低制造成本。接线座的材料宜为铝型材,铝型材包括但不限于6061-T6或6005-T5铝型材。 ...
