Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any inventive step, are within the scope of the present invention.
As shown in figure 1, the utility model is a special operation tool for live disconnection and connection of a lead wire of a 220kV transformer substation, which comprises an insulating ladder head and an insulating rope ladder; the insulation ladder head is composed of two L-shaped insulation rod main bodies 1 and 2 with opposite openings, the two L-shaped insulation rod main bodies 1 and 2 are fixedly connected through two insulation cross rods 3 and 4 and an insulation U-shaped rod 5, a U-shaped ring 6 is arranged at the lower end of the insulation U-shaped rod 5, an insulation rope can be bound on the insulation U-shaped rod 5 when needed, the U-shaped ring 6 can prevent the insulation rope on the insulation U-shaped rod 5 from sliding, an insulation U-shaped rod 7 is arranged between the insulation cross rod 3 at the rear side of the insulation ladder head and the insulation U-shaped rod 5, the insulation U-shaped rod 7 is connected with the two L-shaped insulation rod main bodies 1 and 2 through an L-shaped notch 8, the insulation U-shaped rod 7 can rotate within 90 degrees, is convenient to carry and transport when being parallel to the insulation ladder head and is convenient for an operator to sit when being vertical to the insulation ladder head, pulleys 9 are arranged at the upper ends of the two L-shaped insulation rod main bodies 1 and 2, the insulation ladder head can rotate clockwise after exceeding a lead 12 to hang the lead, the insulating ladder head passes through pulley 9 and slides on the wire, and pulley 9 lower part is equipped with the safety catch 10, and the insulating ladder head hangs and dies the safety catch 10 lock after going into wire 12, prevents that insulating ladder head from deviating from wire 12, and two L type insulator spindle main parts 1 and 2 lower extremes are equipped with ring 11, and insulating ladder head accessible ring 11 is connected with insulating rope ladder 13.
