Description

一种带电作业拆卸和安装高压线T型线夹的装置 技术领域
本发明属于电力检修工程设备领域,具体涉及到一种带电作业拆卸和安装高压线T型线夹的装置。
背景技术
变电站高压线路分布着密密麻麻的高压线T型线夹,其作用是将高压线路向各个城市、乡镇进行分流。但由于高压线T型线夹常年裸露在室外,极易受到天气和环境的影响,例如降雪和刮风会导致高压线产生振动,使得连接板上的螺栓发生松动产生电火花,引发断线事故;同时恶劣环境下连接板上的螺栓也会遭受严重腐蚀,与连接板形成粘接,容易造成事故。因此,高压线T型线夹螺栓的松动或锈蚀现象,不仅是影响电网安全平稳运行的潜在隐患,而且也是对断电片区造成巨大经济损失的主要根源。
在高压线T型线夹螺栓出现松动或锈蚀时,需要及时对螺栓进行更换,以免酿成事故。更换螺栓时若断掉高压母线端电流,会造成母线供电区域停电,对生产、生活造成难以估量的经济损失。故目前一般采用人工在高空与高压母线先建立等电位,再对连接板螺栓进行拆装以完成更换。这种方法基于人工在等电位状态下对高压线T型线夹进行带电作业,作业时会受到带电作业距离的限制,导致作业人员难以施展动作,因而引起螺栓紧固扭矩未能达到国家标准,甚至出现扳手套筒无法套住螺栓的情况。此外,人工等电位带电作业必须经调度部门批准才能进行,其审批流程较为繁琐,导致出现松动或锈蚀的螺栓难以得到及时更换,增加了发生事故的风险。
