Abstract

本申请公开了一种励磁变压器冷却风机更换装置，包括支撑架，支撑架上设置有多个安装板，支撑架的支撑杆分别设置在安装板两侧，每个安装板上设置有风机组件，风机组件包括设置在安装板上端的支撑座，支撑座上安装有电机，电机与叶片传动连接，支撑架下部安装有多组滑轮，滑轮下方设置有滑轨，滑轨下部设置有滑槽，滑轨之间连接有横板；通过拉动支撑架使得安装板带动风机组件从滑轨中滑出到空旷位置进行维修更换，相比于在励磁变压器侧边狭小的维修环境，增加了对冷却风机更换维修的便捷性，将风机组件拉动到远离电气设备的位置进行更换维修，提高了工作人员对冷却风机维修时的安全性，有益于提高对励磁变压器冷却风机的维修效率。
