500kv clamp removal and installation method

Abstract

The invention relates to a method for dismantling and installing a 500kV wire clamp, including equipment wire clamps, wire clamps, and a two-way wire tensioner. The two-way wire tensioner includes a base fixedly installed on the wire wire clamp, and a rotating shaft is horizontally arranged in the base. One end of the rotating shaft is fixedly connected with a winding drum, and the other end of the rotating shaft is connected with a two-way ratchet wrench; a pull rope is threaded between the wire clamp and the bolt hole of the equipment clamp, and the draw rope passes through one end of the equipment clamp and is fixedly connected with a limit card Buckle, the pull cord passes through one end of the wire clamp and is firmly connected to the winding drum; when in use, the winding drum is driven forward and reverse by a two-way ratchet wrench, and then the pull rope is tightened and loosened. When the pull rope is tightened, The wire clamp is close to the equipment clamp until it fits, and the connecting screw is used to connect the two to complete the installation; when the pull rope is loosened, the wire clamp is separated from the equipment clamp to complete the removal. The invention adopts a two-way wire tensioner and a pull rope to cooperate to tighten the wire clamp and the equipment clamp, which is easy to install and remove, convenient to use, and high in assembly and disassembly efficiency.

Description

Technical field: [0001] The invention relates to a method for removing and installing a 500kV line clamp. Background technique: [0002] One of the routine tasks for primary equipment maintenance of 500kV substation is to remove the contact surface between equipment clamps and wire clamps, including wire clamps connected between switches, CTs, and switches, and wires connected to high-voltage side bushings of 500kV transformers. Clips, etc., because the wires are long, the cross-section is large, the torsion, tension, and their own weight are large, and the location is at a height of more than 10 meters, removal and installation are a major problem for maintenance personnel. [0003] The existing 500kV clamp removal and installation method is: rely on daily tools, and the operator stands in the high-altitude vehicle body and pulls the wire manually to complete the removal and installation of the clamp. Because the entire removal and installation depend on manpower, Moreover...

Problems solved by technology

[0003] The existing 500kV clamp removal and installation method is: rely on daily tools, and the operator stands in the high-altitude vehicle body and pulls the wire manually to complete the removal and installation of the clamp. Because the entire removal and installation depend on manpower, Moreover, it belongs to high-altitude operations, the risk of falling from high altitudes is high, and it requires a lot of physical strength of the operators.
