Problems solved by technology

However, the existing on-line monitoring device for breeze vibration of transmission lines cannot guarantee the reliability of the measurement results when measuring the vibration of the conductor.
The reason is that the calibration of the breeze vibration online monitoring device is mainly for the vibration acquisition unit, that is, the vibration sensor, and cannot directly calibrate the entire breeze vibration online monitoring device

Abstract

The invention provides a method of calibrating a transmission line aeolian vibration online monitoring device. The method comprises steps: 1, the transmission line aeolian vibration online monitoring device is connected with a measuring standard device; 2, the vibration excitation frequency and the vibration excitation amplitude outputted by the measuring standard device are set; and 3, the measuring value of the transmission line aeolian vibration online monitoring device is acquired, and the measuring value and the actual output value of the measuring standard device are compared. The method of calibrating the transmission line aeolian vibration online monitoring device provided by the invention has the advantages that the actual working condition of the transmission line aeolian vibration online monitoring device can be simulated to the maximum degree, and data measured by the transmission line aeolian vibration online monitoring device are closer to actual application compared with relative vibration data by an acquisition unit relative to a mounting interface.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of power transmission lines, in particular to a calibration method for an on-line monitoring device for breeze vibration of power transmission lines. Background technique [0002] The periodic vibration generated by the breeze blowing the transmission line, if no anti-vibration measures are taken, may lead to fatigue and broken strands of the conductor, seriously affecting the safety of the line. At present, the power production department generally uses the breeze vibration online monitoring device to measure and monitor the vibration of the transmission line in real time, so as to select appropriate anti-vibration measures. However, the existing on-line monitoring device for breeze vibration of transmission lines cannot guarantee the reliability of the measurement results for the measurement of conductor vibration. The reason is that the calibration of the breeze vibration online mon...
