The galloping of the overhead transmission line seriously threatens the safe operation of the transmission system. The ultra-high voltage transmission conductor galloping is the self-excited vibration with low frequency (about 0.1 Hz-3 Hz) and large amplitude (about 5-300 times of the diameter of a transmission line), has the vibration characteristic of one or more half-wave forms in a span, and belongs to the problem of aerodynamic instability. When the galloping happens, the conducting wire can generate complex coupling vibration in the horizontal direction, the vertical direction and the torsional direction, and the mechanism of the galloping is very complex. The extent of the wire galloping hazard depends on the duration of the wire galloping, the severity of the galloping, and the configuration of the wire. The hazards of the galloping of the power transmission line are as follows: flashover causes disconnection of a system breaker and electric arc burning of the wire, and comprises wire damage, insufficient wire-to-ground distance, loosening of a bolt of the iron tower, fatigue damage of key parts of the iron tower caused by accumulated galloping damage, fatigue damage of a jumper wire joint, fatigue damage of a suspension point of an insulator, damage of an insulator string, damage of a spacer and an anti-vibration hammer and the like. Widely-used electric equipment applied to the transmission line has weaker ability of preventing the transmission line from galloping, has unobvious anti-galloping effect, and can not meet the requirements of long-distance and large-span transmission development of the ultra-high voltage transmission line. The damage of the power transmission line can cause the breakdown of a power supply system, which not only causes great economic loss, but also causes secondary disasters such as fire and the like, and causes great threat to the life and property of the society and people.
