Development of a Maintenance Platform for Three-phase Combined Forced Oil Circulation Air-cooling Transformer
For large capacity hydro-turbine generator units located in remote areas with inconvenient transportation,three-phase combined forced oil circulation air-cooling transformer that is small and easy to transport is often selected.The top space above the oil tank of this type of transformer is narrow and full of pipelines,which limits the maintenance operation space.The installation positions of some sleeves and fire sprinkler systems,as well as the laying of the accident oil pool and pebbles at the bottom of the oil tank,increase the safety risks of maintenance personnel falling from heights,and also make it impossible for the ordinary scaffolding to meet the requirements of on-site maintenance.Therefore,a maintenance platform is developed for the three-phase combined forced oil circulation air-cooling transformer,which is convenient for maintenance,safe and reliable,of strong universality,can be quickly disassembled and assembled,and of low cost.The social and economic benefits are significant.
