A large-current sleeve dismounting device vertically installed on a three-phase combined type main transformer low-voltage connecting box comprises a lift truck, the lift truck comprises supports arranged on the two sides, first lifting rods are arranged on the inner sides of the supports, a second lifting rod is fixedly arranged between the two first lifting rods, and the bottom of the second lifting rod is connected with a sleeve through a connecting piece. The sleeve is driven to move up and down. According to the dismounting device and method for the large-current sleeve vertically installed on the three-phase combined type main transformer low-voltage connection box, a modularized lifting truck is used for replacing a traditional lifting method, the current sleeve is easily pulled out from a transformer oil tank or a voltage connection box installation flange, the sleeve is accurately placed in place, and the dismounting efficiency is greatly improved. Meanwhile, a hoisting device erected on an equipment shell and a framework is used for replacing a roof fixed hoisting point to hoist and translate a large-current sleeve in a closed space. The operation risk, difficulty and workload of dismounting and mounting of the sleeve are reduced, and it is ensured that the large-current sleeve is safely, efficiently and conveniently dismounted and mounted.
三相组合式主变低压连接箱上垂直安装的大电流套管拆卸装置,包括升降车,所述升降车包括设于两侧的支架,在支架的内侧设有第一升降杆,在两个第一升降杆之间固定设有第二升降杆,第二升降杆的底部通过连接件与套管连接,用于带动套管上下移动。本发明提供一种三相组合式主变低压连接箱上垂直安装的大电流套管拆卸装置及方法,利用模块化的升降车取代过去的提拉方法,从变压器油箱或电压连接箱安装法兰轻松上拨出电流套管,并将套管精准落放到位,同时利用搭设在设备外壳及构架上的起吊装置取代房顶固定吊点,起吊、平移封闭空间的大电流套管。降低了套管拆装的作业风险、难度及工作量,确保安全、高效、便拆装大电流套管。
