500kV compact type electric transmission line three-phase bundled conductor galloping simulation test platform

Abstract

The invention discloses a 500kV compact type electric transmission line three-phase bundled conductor galloping simulation test platform. The 500kV compact type electric transmission line three-phase bundled conductor galloping simulation test platform is characterized by comprising a three-phase bundled conductor traction field system, a three-phase bundled conductor galloping platform system and a three-phase bundled conductor tension field system. A three-phase bundled conductor is erected through a reaction wall and a tension end steel framework, a bundled conductor galloping testing machine exerts vibration on the three-phase bundled conductor, three-phase bundled conductor galloping in the actual engineering is simulated, and therefore galloping fatigue test research, galloping-prevention performance test research and novel galloping-prevention fitting development test research can be carried out on the three-phase bundled conductor and a whole inter-phase spacer composed of an inter-phase spacer body and an inter-phase spacer connecting fitting. The 500kV compact type electric transmission line three-phase bundled conductor galloping simulation test platform has the advantages of being real in simulation, reliable in result and the like.

Description

technical field [0001] The invention is a 500kV compact power transmission line three-phase split wire galloping simulation test platform. Background technique [0002] In the construction of my country's power grid, due to the construction of a large number of water, thermal and nuclear power plants in recent years, large-scale, long-distance, and large-capacity power transmission projects have also appeared one after another. However, due to the limitation of line corridors, 500kV compact power transmission Lines have become a subject of much concern in the construction of ultra-high voltage power grids. However, conductor galloping is a difficult point in the research of 500kV compact transmission lines. The galloping of conductors will not only cause damage to towers, conductors, fittings and components, but also cause frequent tripping and power outages of the line, endangering the safe operation of transmission lines, and causing major damage. Economic losses affect th...

Problems solved by technology

The direct reason is that there has been no "500kV compact transmission line three-phase split conductor galloping simulation test platform", to conduct galloping fatigue test research and anti-galling performance test research on the overall interphase spacer, but to use the interphase spacer in the overall interphase spacer The main body and the interphase spacer connecting fittings are separated, and the galloping fatigue test and the galloping performance test are carried out separately. The actual running state of galloping of the three-phase split conductors of the 500kV compact transmission line is not simulated, which makes the simulation lack of authenticity. The simulation results are consistent with the actual Large error
