Description
technical field [0001] The invention relates to the technical field of overhead transmission lines, in particular to a galloping detector for transmission lines. Background technique [0002] During the operation of overhead transmission lines, various disasters and accidents will occur due to natural conditions, threatening the safe and stable operation of the line, and galloping is one of the more serious hazards. Transmission line galloping is a phenomenon caused by aerodynamic instability. The occurrence of galloping in transmission lines is mainly due to the occurrence of large-scale rime weather under special meteorological conditions, which makes the surface of overhead transmission lines covered with ice, and the transmission lines generate low frequency (0.1-3.0) Hz and large amplitude (approximately 20 to 300 times the wire diameter) self-excited vibration. Galloping causes various hazards, such as flashover and tripping in light cases, damage to hardware and ins...
