(2) an maintainer holds an insulating rod of the installation assembly by hand, an electric clamping jaw at the upper end of the insulating rod clamps a balance weight cylinder of a connecting piece, moves the balance weight cylinder to the upper part of a bolt at the top of the transformer, sleeves a through hole at the upper end of a safety belt on the bolt at the top of the transformer, controls the electric clamping jaw to open and close, moves the electric clamping jaw to the position near a nut, controls the electric clamping jaw to clamp the nut, and then swings the insulating rod to enable the nut to be in threaded connection with the bolt at the top of the transformer;
(3) fix the safety belt lower extreme at the maintainer waist, the maintainer climbs to on overhauing the operation platform through the both sides ladder, overhauls the operation, overhauls the in-process, if the height of overhauing the platform is not enough, lifts up the second plate body of folded sheet, opens the folding leg of second plate body below to support the tip of third plate body in connecting rod one side, fixed stay.
