Embodiment

[0012] Embodiments Embodiments will be described below with reference to the drawings.

[0013] A double-split wire equipotential outlet pulley, which includes two pulley blocks with the same structure, and four pulleys are installed between the left connecting plate 6 and the right connecting plate 11 of each pulley block through the pulley shaft, respectively the first pulley 1. The second pulley 2, the third pulley 4 and the fourth pulley 5. The first pulley 1 will be located below the lower conductor 10 of the double-split conductor, the second pulley 2 will be located above the lower conductor 10 of the double-split conductor, and the third pulley 4 will be located below the upper conductor 7 of the double-split conductor , the fourth pulley 5 will be positioned above the upper wire 7 in the double split wire. Weld the fulcrum 9 on one side connecting plate 6 of one pulley block, weld the positioning rod 3 on the same side connecting plate 6 of the other pulley block, on...

Abstract

Disclosed is an equipotential outlet trolley for a double bundle conductor. The trolley is characterized by comprising two sliding wheel groups with identical structures, each of the two sliding wheel groups comprises four sliding wheels installed between connection plates on two sides through sliding wheel shafts. A support shaft is installed on the connection plate on one side of one of the sliding wheel groups, and a locating rod is installed on the connection plate on the same side of the other sliding wheel group. One end of a movable insulating plate is hinged to the support shaft, and the other end of the movable insulating plate is matched with the locating rod. So as to facilitate the assembly, the two sliding wheels on the upper portion of a conductor and the two sliding wheels on the lower portion of the conductor are installed on two connection plates respectively and assembled at high altitudes. By means of the equipotential outlet trolley for the double bundle conductor, 220-KV double bundle conductors can be subjected to living outlet operation, so that living operation distances among phases can meet technical requirements, personnel and device securities are guaranteed, and the field operation security is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power transmission, and in particular relates to a double-split wire equipotential outlet pulley used for professional work on live lines such as power system operation and maintenance. Background technique [0002] During the operation and maintenance of the power system, it is often necessary for operators to enter the strong electric field to install spacers, deal with broken strands of wires, and overheating of crimping tubes. In the past, workers entered the electric field through insulating ladders. Since the double wires were easy to separate, gap discharges were caused, and the potential risk was high. Contents of the invention [0003] In order to solve the problem of personal safety in power system operation and maintenance live work, the following technical solutions are proposed. [0004] A double-split wire equipotential outlet pulley, its special feature is that it includes two ...
