Description
Technical Field
The utility model relates to a transmission line detection technology field that waves especially relates to a transmission line monitoring system that waves's coupling mechanism.
Background
In the transmission line, when the wire is subjected to the action of a transverse velocity wind load, a downward acceleration motion is generated, and the wire is subjected to the action of an aerodynamic moment to generate torsion. Conductor galloping occurs when the frequency of the torsional motion is synchronized with the frequency of its vertical motion. The conductor galloping is a low-frequency (0.1-3 HZ) and large-amplitude (> 10 m) vibration phenomenon, the galloping wave is a standing wave, and the full-gear overhead line does large-amplitude wave-type vibration during galloping and also swings. Conductor galloping is an important factor threatening the safe operation of the power grid. Besides causing electrical faults, conductor galloping also causes serious mechanical damages such as bolt looseness and falling, hardware fittings, insulators and jumper wire damage, strand breakage and wire breakage of the conductor, damage of tower materials and foundations and the like.
At present, the anti-loosening performance of an iron tower bolt is improved by the adoption of line galloping; the strength of key parts of the tower and related hardware fittings is properly improved; the span and the length of the strain section are properly reduced, the line trend of local areas is changed, and advance measures such as galloping zones are avoided. However, due to the limitation of the technical level of the prior art, along with the increase of the service life, the anti-loosening performance of the iron tower bolt is reduced, the key part of the tower and related hardware fittings are deformed, and the measures cannot completely stop line galloping. In order to prevent further damage from line galloping, line galloping must be detected in order to take action. The existing power transmission line galloping can only be detected to a specified point manually at regular intervals, and due to the fact that the detection points are numerous and are widely distributed in regions and are mostly distributed on barren mountains and mountains, detection efficiency is low and detection cost is high.
