Description

Technical Field

[0001] The invention relates to a transmission line sub-conductor anti-adhesion isolation wire clamp and method that can be installed live, belonging to the technical field of transmission line operation and maintenance. Background Art

[0002] Wire adhesion and whipping: Whipping refers to the phenomenon that the electromagnetic force of the upper wire on the lower wire is greater than or equal to the deadweight of the lower wire under the influence of comprehensive factors such as current, temperature, wind speed, and light, resulting in the two wires "sticking" together. The upper and lower wires keep sticking, separating, sticking again, and separating again, making a loud friction sound, like the sound of a whip. Whipping can cause wire strand breakage, irregular elongation, and other phenomena, and the current-carrying capacity and mechanical stress will decrease. If not handled in time, there is a risk of line breakage. Once whipping occurs on a transmission line, the line maintenance personnel will immediately rush to the site for maintenance and promptly eliminate potential safety hazards in the line.

[0003] The conductors of 220kV power supply system are mostly arranged vertically in double split form, that is, double split sub-conductors: each phase conductor in the transmission line is composed of two conductors of a certain cross-section, which is an upper and lower structure. The distance between the two conductors is between 30-50 cm, which is used to increase the single-phase transmission cross-section of the transmission line to reduce the generation of corona in the line and improve the power transmission capacity of the line. The 220kV line is generally split in two. Affected by environmental factors such as strong winds, local micro-meteorology, ice and snow adhesion, and superimposed with internal factors such as increased concentrated output load of new energy transmission, transmission lines in high-cold areas (such as the Bashang area of ​​Chengde) are prone to adhesion and whipping of sub-conductors, which causes wear, strand breakage and even line breakage between sub-conductors. Taking manual power outage to install isolation wire clamps is an important way to solve the above problems, but there are practical problems such as the need for line power outage, long operation hours, difficulty in manual line operation, and large swing of the operation point due to gusty weather. Slight dancing during large-spacing phase-to-phase operation may even cause insufficient safety distance, which directly endangers the personal safety of emergency workers.

[0004] The Chinese patent in the prior art "A tool for preventing phase-split conductors from sticking together" has an application number of CN202121241364.0 and an application date of 2021.06.04. The technical solution is: external connection plates are provided on both sides of the connecting hardware, and an adjustment hole is provided at the bottom end of the connecting hardware. The top and middle ends of the connecting hardware are respectively movably connected with connecting shaft one and connecting shaft two, and the left and right sides of connecting shaft one and connecting shaft two are meshed with fixing nut one, and the top of the external connection plate and the inner cavity of the adjusting hole are movably connected with a plug-in shaft, and the left and right ends of the plug-in shaft are meshed with fixing nut two, and the middle part of the plug-in shaft is movably connected with a hanging plate, and a wire wrapping clamp is fixedly installed at the bottom end of the hanging plate, and connecting buckles are provided at the front and rear ends of the wire wrapping clamp, and the bottom end of the connecting buckle is movably connected with a bottom plate, and the bottom end of the connecting buckle is meshed with fixing nut three. When in use, wrap the wire clamp at the top of the external connection plate on the surface of the upper split conductor, wrap the wire clamp at the bottom end of the connecting hardware on the surface of the lower split conductor, and then use two connecting buckles to buckle on the left and right sides of the two wire clamps respectively, pass the bottom plate through the bottom end of the connecting buckle, and then tighten the fixing nut three, so that the two split conductors can be fixed; when installing, plug the hanging plate into the middle of the plug-in shaft, so that the two wire clamps are respectively fixed on the top of the external connection plate and the bottom end of the connecting hardware, and then tighten the fixing nut two, so that the plug-in shaft is fixed to the connecting hardware and the external connection plate; when it is necessary to adjust the distance between the two split conductors, just unscrew the fixing nut two at the bottom end of the connecting hardware, and then pull the connecting shaft out of the adjustment hole, and then plug the connecting shaft downward into the corresponding adjustment hole, so as to adjust the distance of the wire clamp at the bottom end of the connecting hardware, that is, adjust the position of the lower split conductor downward. However, the above-mentioned existing technology is based on manual installation, with high labor costs, many operations at high places, and high construction safety risks. When in use, most of them adopt means such as adjusting the installation of spacers in the sub-conductors and increasing the sub-conductor spacing of the suspension wire clamp. The length of the spacer is fixed. Although the sag of the two sub-conductors of the double-split conductor should be the same in the design of the conductor, both the influence of the natural environment and the error during construction will cause a certain high sag difference between the two sub-conductors. When laying out the wire, if the upper sub-conductor is laid out less than the design, the upper sub-conductor will forcibly pull the lower sub-conductor through the spacer, which will seriously increase the wear of the conductor, and the displacement of the spacer due to the wear of the conductor will occur. In severe cases, the aluminum wire of the sub-conductor will break. If the lower sub-conductor is laid out larger during laying out, the upper sub-conductor will bear the deadweight of another sub-conductor due to the spacer, and the wear of the conductor will also increase, and the force will be close to the breaking force, causing problems such as broken strands. Therefore, the use of spacers will lead to poor stability, heavy workload, and heavy tools. Therefore, it is necessary to shut down the power supply for installation, resulting in reduced power supply reliability. Summary of the invention
