220kV双分裂导线专用挂脚滑车的设计

Design of hook pulley specially used for 220kV two bundled lines

通过对220kV双分裂导线出线检修工作方法的分析,找出了目前检修工作中存在的技术难点,设计了一种适用于220kV双分裂导线输电线路的专用检修挂脚滑车,可较好地解决检修中的问题。

According to the analysis on overhaul process of 220kV two bendled conductors output line,the technical difficult points existed in current overhaul work were found.A hook pulley,which is specially suitable for overhaul of 220kV two bendled conductors transmission line,was designed;and the problem in overhaul can be better solved by using the pulley.
