Description
技术领域 technical field
本发明涉及一种电力隔离开关检修专用工具,尤其是一种适用于对GW5型隔离开关检修的专用吊架,属于发电、变电或配电技术领域。 The invention relates to a special tool for overhauling a power isolating switch, in particular to a special hanger suitable for overhauling a GW5 type isolating switch, and belongs to the technical field of power generation, transformation or distribution.
背景技术 Background technique
变电站隔离开关在长时间运行后,会出现转动部位锈死现象,使隔离开关的操作非常困难,因此需要对隔离开关的轴承进行定期检修和维护。一般隔离开关轴承位于支持瓷瓶的底部,在对轴承检修时,必须首先将支持瓷瓶拆卸(参看附图1、附图2)。由于支持瓷瓶的重量较大,例如GW5型防污隔离开关一侧支持瓷瓶重量为75KG,普通隔离开关一侧支持瓷瓶的重量为52KG,如果采用徒手拆卸方式,不仅操作者劳动强度大,而且存在着安全隐患;如果利用吊车辅助拆卸,受场地限制和停电范围的影响,实施起来也相当困难。 After the substation isolating switch has been in operation for a long time, the rotating parts will rust and die, which makes the operation of the isolating switch very difficult. Therefore, the bearings of the isolating switch need to be inspected and maintained regularly. Generally, the bearing of the isolating switch is located at the bottom of the supporting porcelain bottle. When the bearing is overhauled, the supporting porcelain bottle must be disassembled first (see attached drawings 1 and 2). Due to the heavy weight of the supporting porcelain bottle, for example, the weight of the supporting porcelain bottle on one side of the GW5 anti-pollution isolating switch is 75KG, and the weight of supporting the porcelain bottle on the side of the ordinary isolating switch is 52KG. If a crane is used to assist dismantling, it is also quite difficult to implement due to site restrictions and the scope of power outages.
