Problems solved by technology

This utility model patent uses the function of the damper to consume energy and reduce the energy amplitude, but on the one hand, the coupling effect between the line and the tower does not change, and on the other hand, it may cause the spectrum overlap between the transmission tower and the wire, and strengthen the wire and the internal resonance effect of the transmission tower, aggravating the vibration of the transmission tower

Abstract

The invention discloses a power transmission tower and insulator connecting device based on hydraulic dampers. One end of a universal spherical hinge is connected with a cross arm of a power transmission tower, one end of a connecting end plate is hinged with an insulator, vertical hydraulic dampers are vertically placed in a frame formed by connecting upper and lower connecting plates and peripheral side plates, a piston of each vertical hydraulic damper is connected with an inner plate, a plurality of small hydraulic dampers are connected to the periphery of the lower portion, a plurality ofsmall hydraulic dampers are connected to the periphery of the inner plate, and the free ends of the small hydraulic dampers are placed in grooves of the side plates and slide horizontally; the vertical hydraulic damper and the small hydraulic damper control displacement and energy consumption in the vertical direction and the horizontal direction through stretching and retracting, and the coupling effect of the power transmission tower and the wire is reduced. The device has the advantages that the coupling effect of the power transmission tower and the wire is weakened, and the wind resistance of the tower wire is effectively improved.

Description

technical field [0001] The invention relates to the technical field of transmission line devices, in particular to a connection device between a transmission tower and an insulator based on a hydraulic damper. Background technique [0002] The transmission tower-line system includes transmission towers, conductor (ground) wires, insulators and fittings, and has the characteristics of a tower-like structure and a large-span structure. [0003] The structure of the transmission tower is high and flexible, and the span of the transmission wire is large, which determines that the transmission line itself is a wind load sensitive structure. Unbalanced energy distribution, geographical differences between load centers and power generation centers, high-voltage, ultra-high-voltage, and ultra-high-voltage lines are constantly being built, and the span of transmission lines is constantly increasing, and the height of transmission towers is also constantly rising. The disaster proble...
