Connection device for transmission towers and insulators based on hydraulic dampers

Abstract

The invention discloses a connection device for a transmission tower and an insulator based on a hydraulic damper. One end of the universal ball joint is connected to the cross arm of the transmission tower, one end of the connection end plate is hinged to the insulator, and the vertical hydraulic damper is vertically placed on the upper and lower parts. In the frame formed by connecting the connecting plate and the surrounding side plates, the piston is connected with the inner plate, and the outer periphery of the lower part is connected with multiple small hydraulic dampers, and the outer periphery of the inner plate is connected with multiple small hydraulic dampers. The free ends of the small hydraulic dampers are into the groove of the side plate and slide horizontally; the vertical hydraulic damper and the small hydraulic damper control the displacement and energy consumption in the vertical and horizontal directions through expansion and contraction, and reduce the coupling effect between the transmission tower and the wire. The invention has the advantages of weakening the coupling effect between the transmission tower and the wire, and effectively improving the wind resistance of the tower wire.

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...

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
