The invention discloses a typhoon-prevention damping wire clamp for an electric transmission wire of a straight pole and tower. The typhoon-prevention damping wire clamp comprises a hanging plate, a wire clamp ship body and damping springs, wherein the upper end of the hanging plate is arranged on a cross arm of the straight pole and tower, and the wire clamp ship body is arranged at the lower endof the hanging plate; a transverse wire through hole is formed in the wire clamp ship body, a spring groove is concavely formed in the inner wall of the wire through hole, and the damping springs arearranged in the spring groove. The wire through hole is formed in the wire clamp ship body, after the electric transmission wire penetrates through the wire through hole, when the electric transmission wire vibrates or gallops under the action of a typhoon, the self weight of the electric transmission wire and wind load are mainly borne by the damping springs, and typhoon prevention and shock absorption can be conducted by using the damping characteristics of the damping springs, so that the electric transmission pole and tower are protected.
Description
technical field [0001] The invention relates to the field of disaster prevention and mitigation of power grid power transmission equipment, in particular to a vibration-damping clamp for a straight pole tower power transmission wire used for typhoon prevention. Background technique [0002] Under the action of strong wind or typhoon, it has the greatest impact on the operation of coastal transmission lines; if the windproof design level of transmission towers is lower than the actual wind speed, transmission equipment such as transmission towers will be damaged, which will affect the operation of the grid and the reliability of power supply, especially after disasters It takes a lot of time to repair and restore the normal operation of the transmission tower, which greatly affects the reliability of the power supply of the power system. The power transmission of the grid mainly depends on the transmission wire, which is suspended on the transmission tower through the clamp. ...
