Description

Technical Field

[0001] The utility model relates to the technical field of disaster prevention and reduction of power grids, and in particular to an anti-dancing device. Background Art

[0002] Galloping is a low-frequency, large-amplitude self-excited vibration phenomenon caused by eccentric icing and strong winds on overhead wires. It occurs because overhead wires are affected by icing and strong winds.

[0003] Eccentric icing is a key factor in inducing galloping. It causes the conductor to be subjected to additional vertical lift and torsional torque. Under certain conditions, the aerodynamic damping force on the conductor not only fails to consume the low-frequency vibration energy, but will cause the energy to accumulate continuously, causing more and more intense vibrations, thereby inducing galloping and eventually causing the conductor to break, posing a safety hazard. In particular, overhead wires passing through railway lines and highways will intensify the galloping of the wires when trains and cars pass by, greatly increasing the probability of wire breakage. Once a wire breaks, it can easily cause a major safety accident. In traditional technical means, after the galloping occurs, the on-site operation and maintenance personnel do not have any emergency management technical means such as active suppression, elimination and stopping, and can only wait for it to stop and eliminate on its own.
