Description

technical field [0001] The invention relates to the technical field of ultra-high voltage power grids, in particular to a real-time monitoring device and method for the dancing tension of interphase spacer rods of transmission lines. Background technique [0002] Galloping of transmission lines is a self-excited vibration with low frequency (0.1-5 Hz) and large amplitude (20-300 times the diameter of the wire) generated by uneven ice-coated wires under wind excitation. Galloping energy of high-voltage transmission lines is large and lasts for a long time, which can easily cause line flashover, tripping, loosening and falling off of tower bolts, and in severe cases, hardware and insulators will be damaged, wire strands and wires will be broken, and even towers will collapse, leading to major power grid accidents. [0003] As an effective means of galloping suppression, interphase spacers are introduced on a large scale. The on-site interphase spacer is suspended between the ...

Problems solved by technology

This method uses the method of image processing to monitor the galloping of the wire according to the difference shape of the template contour matching of the spacer before and after the galloping, and can realize the detection of the torsion angle of the galloping of the wire. , the quality of the captured digital image is difficult to guarantee, and it is difficult to accurately monitor the wire galloping

Moreover, this method can only monitor the galloping of the wires, and cannot monitor the mechanical properties such as tension and pressure on the interphase spacers during the galloping process.
