针对用电负荷不断上升，新建变电站工程不断增多导致的工作量大大提升和传统吊装穿线装置低效等问题，提出一种面向室内变电站机组吊装的穿线装置。这种穿线装置利用触发块和上下推拉机构解除机构锁定，通过配重块下落，带动在可调速收线盘上的尼龙绳穿线，最后牵引钢丝绳完成穿线。本文将穿线装置应用于室内变电站机组吊装测试，结果表明，穿线过程耗时短，效率高，安全性高，且满足室内变电站机组吊装的工作要求。
Aiming at the problem that the electric load is rising, the workload of the new substation project is increasing, and the traditional hoisting and threading device is inefficient, a threading device for indoor substation unit hoisting is proposed. The threading device utilizes the trigger block and the up and down push-pull mechanism to unlock the mechanism, and the nylon rope is threaded on the adjustable speed take-up reel by the weight falling, and finally the wire rope is threaded. In this paper, the threading device is applied to the indoor substation unit hoisting test. The results show that the threading process is short in time, high in efficiency, high in safety, and meets the working requirements of indoor substation unit hoisting.
