Power transmission tower wire anti-windage yaw device and method

By using a wind-response damper that is fixedly connected to the crossarm of the tower and supported by a support component, combined with an information acquisition module and a controller, the opening of the damping hydraulic valve is adjusted in real time. This solves the problem that traditional wind deflection prevention measures are ineffective under extreme conditions, and effectively suppresses conductor vibration and ensures stable operation of the device.

Abstract

The invention provides a power transmission tower wire windage yaw preventing device and method, and belongs to the technical field of power transmission line safety equipment. The power transmission tower wire windage yaw prevention device comprises a supporting assembly, an insulating rod, an information acquisition module and a controller. The supporting assembly is fixedly connected to an iron tower cross arm. A wind response damper is hinged to the end of the supporting assembly. The wind response damper is used for absorbing vibration of the wire. The top end of the insulating rod is connected with the wind response damper, and the bottom end is hinged with a connecting assembly; the top of the connecting assembly is fixedly connected with an iron tower cross arm. And the information acquisition module is used for outputting and acquiring wind speed information. The controller is in communication connection with the information acquisition module and the wind response damper; the controller is configured to: receive wind speed information; the opening degree of a damping hydraulic valve in the wind response damper is adjusted according to the wind speed information, so that vibration of the wire can be absorbed in different weathers. A set of system with structure supporting and dynamic adjusting functions is constructed, and the windage yaw preventing effect is synergistically improved from the two aspects of structure stability and damping adaptability.
