Abstract: In order to improve the automation level of distribution lines, the number of FTU of distribution lines has increased sharply, and the workload of relevant operation and maintenance has increased greatly. The existing operation and maintenance mode of hood type FTU has the following problems: the preparation process is cumbersome, the time is long and the efficiency is low; Operators have the risk of falling from height; The site environment is complex, and it is difficult or impossible to climb the pole in some weather or terrain. This paper introduces the development process of a kind of non climbing lever for distribution automation hood type FTU. This device can simplify the operation and maintenance process of distribution automation FTU, and improve the operation efficiency and the operation safety level of operation and maintenance personnel.
