Research On On-line Monitoring System Of Zhenjiang Yangtze River Long Span Transmission Line Aeolian Vibration

Of aeolian vibration fatigue caused by the wire off shares is a major threat to the safe operation of the transmission line. The breeze vibration of high-voltage overhead line conductors is due to the incentive effect of the wind caused by a high frequency, small amplitude of the wire movement, prevalent in the high-voltage overhead lines. Leap, especially in large due to the span, suspension and some open waters, the impact of micro-meteorological conditions of wind direction and wind speed, temperature, etc., greatly increased the vibrational energy of the wind lost wire, wire vibration strength than ordinary files from the serious. Breeze vibration caused by the conductivity, ground fatigue accident off shares, through the cumulative effect of a cumulative process and time. The large amount of evidence that:aeolian vibration of a serious threat to the overhead transmission lines, especially the big leap safe operation. Big leap in the operation of the transmission line has a special and important position in the event of the fatigue damage of certain circuit components, such as Grounded the OPGW fatigue off shares, fittings, spacers and tower components fatigue damage or wear will be a serious threat to the safe operation of the transmission line, causing major losses to the national economy. Therefore, the span of the anti-vibration and monitoring has been of concern for the line workers, important for the design, operation and scientific research departments.Discussed in aeolian vibration of the mechanism of transmission lines, the online measurement system span guide, ground monitor and IT remote monitoring, and measurement data were analyzed in order to line operation and maintenance work to help.
