Abstract
The invention relates to a live processing device and a processing method for poor contact of an ultra high-voltage transmission line jumper current guiding plate. the processing device comprises a live operation fastening clamp main body, a lengthened insulated handle and a transverse lever tightening armrest, wherein the live operation fastening clamp adopts a G type structure form of a live loading and unloading clamp and is made of a titanium-aluminum alloy, a conductive coating is sprayed on the surface, connection between the clamp and the wire is carried out when the transverse lever tightening armrest axially rotates to apply pressure to the wire, and the current guiding wire for live processing of the poor contact defect work on the ultra high-voltage transmission line current guiding plate is made of a soft copper stranded wire. An insulating tape is used for being tightly wound at the end part of the bare copper stranded wire and the three-dividing point position of the copper stranded wire, a hydraulic compression mode is adopted to connect the copper stranded wire and the clamp, the insulating tape is used for being wound at the connection part, and the copper wire can be prevented from being separated by a steel sheet. The technical scheme provided by the invention is simple, safe and convenient.
Description
technical field [0001] The invention relates to a treatment device and a treatment method for extra-high voltage live work, in particular to a treatment device and a treatment method for poor contact of a jumper drain plate of an extra-high voltage line. Background technique [0002] UHV lines, as the backbone grid in the future, are responsible for the transmission of large load currents. The reliability of operation is extremely high, and it is very difficult to conduct power outage maintenance. to huge direct and indirect losses. In the prior art, the common method to deal with the poor contact defect of the line jumper drain plate is power outage treatment: after the equipment is turned over for maintenance, the drain plate is disassembled, the contact surface is polished, cleaned, conductive paste is applied, and the bolts are tightened. When limited by factors such as system reliability, and based on the consideration that the load current cannot be interrupted, the l...
