Description

一种变压器顶盖升降装置Lifting device for a transformer top cover

技术领域 technical field

本发明涉及电网检修设备技术领域,尤其涉及一种变压器顶盖升降装置。 The invention relates to the technical field of power grid maintenance equipment, in particular to a lifting device for a transformer top cover.

背景技术 Background technique

变压器是工矿企业与民用建筑供配电系统中的重要设备之一,通常采用油浸式变压器,即变压器的器身(包括绕组与铁芯)都装在充满变压器油的油箱中,油箱用钢板焊成,中、小型变压器的油箱由相配装的箱壳和顶盖组成,变压器的器身放在箱壳内形成变压器本体,将顶盖打开就可对器身进行检修。 The transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. Oil-immersed transformers are usually used, that is, the body of the transformer (including windings and iron cores) is installed in an oil tank filled with transformer oil, and the oil tank is made of steel plates. Welded, the oil tank of medium and small transformers is composed of matching box shell and top cover. The transformer body is placed in the box shell to form the transformer body, and the top cover can be opened to repair the body.

在电网运行管理中,变压器更换高低压导电杆是日常维修的一项重要工作,变压器高低压导电杆是变压器中容易损坏的部件,它通常固定在变压器顶盖上,在维修更换时,通常需要将变压器顶盖抬起,由于设备比较沉重,通常采用吊机来拆卸,拉到维修车间修理更换,这样的传统维修方式会带来以下问题:变压器沉重,导致拆装困难,运输业较为困难,道路好的情况用吊车或叉车或手动葫芦等工具拆下装上,还得用车辆拉,部分配变坐落位置偏僻,车辆到不了现场,还得多人抬进抬出,这会导致维修进度慢,停电时间长而且维修费用也高;传统采用搭三角架倒链提拉的方法将变压器顶盖吊起,该方法效率低下,而且容易在起吊时晃动而碰伤变压器,造成不必要的麻烦。 In the operation and management of the power grid, replacing the high and low voltage conductive rods of the transformer is an important task for daily maintenance. The high and low voltage conductive rods of the transformer are easily damaged parts in the transformer. They are usually fixed on the top cover of the transformer. Lift the top cover of the transformer. Because the equipment is heavy, it is usually disassembled by a crane and pulled to the maintenance workshop for repair and replacement. This traditional maintenance method will bring the following problems: the transformer is heavy, which makes disassembly and assembly difficult, and the transportation industry is more difficult. If the roads are good, use tools such as cranes, forklifts, or manual hoists to remove and install them, and vehicles have to be used to pull them. Some distribution units are located in remote locations, and vehicles cannot reach the site. Many people have to carry them in and out, which will lead to maintenance progress. Slow, long power outage and high maintenance costs; the traditional method of lifting the top cover of the transformer with a tripod is used to lift the top cover of the transformer. This method is inefficient, and it is easy to shake and damage the transformer during lifting, causing unnecessary troubles .
