The invention provides a transformer on-load tap-changer hoisting device. The transformer on-load tap-changer hoisting device comprises a base, a supporting rod, a hoisting arm, a hoisting hook and ahoisting hook position adjusting mechanism. The base is used for being connected with a flange plate of an on-load tap-changer. The hoisting hook position adjusting mechanism comprises a first motor,a telescopic rod, a sliding rod, a fixed rod, a front pulley, a rear pulley and a second motor. The first motor is arranged at the tail end of the hoisting arm. One end of the telescopic rod is connected with the first motor, and the other end of the telescopic rod is connected with the sliding rod. The sliding rod is arranged at the front end of the hoisting arm in a sliding manner, is connectedwith the telescopic rod, and is provided with the front pulley. The fixed rod is arranged at the rear end of the hoisting arm and is provided with the rear pulley. The second motor is arranged on thesupporting rod and connected with the hoisting hook through a rope. The rope is supported on the front pulley and the rear pulley respectively. By means of the transformer on-load tap-changer hoistingdevice, hoisting inspection work in overhaul of the indoor transformer on-load tap-changer can be greatly facilitated, the hoisting inspection time is shortened, the problem that due to the narrow top space of an indoor transformer, hoisting cannot be carried out conveniently is solved, and then the work efficiency is improved.
本发明提供了一种变压器有载分接开关起吊装置,包括:底座、支撑杆、吊臂、吊钩和吊钩位置调节机构,底座用于与有载分接开关的法兰盘连接,吊钩位置调节机构包括第一电机、伸缩杆、滑动杆、固定杆、前滑轮、后滑轮和第二电机,第一电机设置在吊臂的尾端,伸缩杆一端与第一电机连接,另一端与滑动杆连接,滑动杆滑动设置在吊臂的前端并与伸缩杆连接,设置有前滑轮,固定杆设置在吊臂的后端,设置有后滑轮;第二电机设置在支撑杆上,通过绳索与吊钩连接,绳索分别支撑在前滑轮和后滑轮上。本发明能够极大的方便室内变压器有载分接开关大修中吊检的工作,减少吊检时间,解决因室内变压器顶部空间狭窄而不方便起吊的问题,进而提高工作效率。
