The invention discloses a rapid connection device for jumper of power transmission lines. The rapid connection device comprises a first connection pipe, a second connection pipe and a middle connection pipe, wherein conical openings are formed in two ends of the middle connection pipe, and an annular clamp groove is formed in the inner side of each conical opening of the middle connection pipe; connecting screw holes I are formed in the annular clamp grooves; a plurality of connecting jaws are arranged at one ends of the first connection pipe and the second connection pipe and arranged annularly; one ends of the connecting jaws are rotationally connected with end parts of the first connection pipe or the second connection pipe through torsion springs, and connecting screw holes II are formed in the other ends of the connecting jaws; the connecting jaws are connected with the annular clamp grooves through bolts; guide grooves are formed in the inner walls of the conical openings; guidebulge blocks sliding along the guide grooves are arranged on the connecting jaws; jumper clamp devices are arranged at outer ends of the first connection pipe and the second connection pipe. The rapidconnection device is simple in structure and stable in connection.
Description
technical field [0001] The invention relates to the technical field of electric equipment, in particular to a jumper quick connection device for power transmission lines. Background technique [0002] At present, there are mainly two types of connecting tooling for jumpering overhead power transmission lines, one is bolt parallel groove clamps, and the other is hydraulic connecting pipes. The use of bolts and trench clamps has the problems of small contact surface, large contact resistance and unreliable connection. When using hydraulic connecting pipes, due to the heavy hydraulic equipment, there are defects such as high-altitude hydraulic operation is difficult, the working hours are long, and it cannot adapt to the change of power grid operation mode. Contents of the invention [0003] The purpose of the present invention is to provide a jumper quick connection device for transmission lines to ensure the safe operation of the power grid. [0004] In order to solve the...
