Description

technical field [0001] The invention relates to a transmission line galloping testing method and device, in particular to a transmission line galloping dynamic data collection method and device. Background technique [0002] Due to the eccentric icing of the wires of the transmission line, a low-frequency, large-amplitude self-excited vibration generated under wind excitation is called galloping. This vibration and galloping have no consistency between the phase lines and are extremely It may cause insufficient air gap between conductors, resulting in flashover and tripping, and at the same time, it will cause serious damage to the anti-vibration and anti-galling fittings and devices installed in the gear, resulting in serious consequences such as slipping of spacers, loosening and breaking of anti-vibration hammers, and even causing insulators to fail. , Damage to connecting fittings and iron towers.

Problems solved by technology

[0002] Due to the eccentric icing of the wires of the transmission line, a low-frequency, large-amplitude self-excited vibration generated under wind excitation is called galloping. This vibration and galloping have no consistency between the phase lines and are extremely It may cause insufficient air gap between conductors, resulting in flashover and tripping, and at the same time, it will cause serious damage to the anti-vibration and anti-galling fittings and devices installed in the gear, resulting in serious consequences such as slipping of spacers, loosening and breaking of anti-vibration hammers, and even causing insulators to fail. , damage to connecting fittings and iron towers

[0003] In the traditional technology, the method of simulating icing by bonding the airfoil resin to the wire, and then using the fan to drive the wire galloping is similar to the actual wire galloping, but the cost is extremely high and the galloping effect is difficult to control. In order to solve the above problem, a method and device for collecting dynamic data of transmission line galloping are now provided
