Problems solved by technology

Moreover, when the transmission wire is in a continuous and stable wind area, this vertical oscillation will last for a long time, which will cause the strands of the wire to dissipate wind energy through friction between the strands for a long period of time
This friction between the wire strands will cause the wear of the

Abstract

The invention provides a vertical vibration attenuation device and a method for determining the mass of a damping liquid medium in the vertical vibration attenuation device. The vertical vibration attenuation device comprises a rectangular inner shell, a rectangular outer shell, a cover plate connected with the rectangular outer shell and a wire chuck positioned on one side of the cover plate, andthe inner shell is a closed inner shell for accommodating the damping liquid medium; and damping pieces are arranged between the upper end of the inner shell and the inner wall of the outer shell andbetween the lower end of the inner shell and the inner wall of the outer shell in the axial direction. Two energy consumption structures are packaged in the vertical vibration attenuation device, thetwo energy consumption structures can consume and dissipate vertical wind vibration energy, and in addition, the damping liquid medium in the inner shell can improve the energy consumption effect. Therefore, the two energy consumption systems can effectively reduce vertical wind vibration of a large-span wire within the span.

Description

technical field [0001] The invention relates to the technical field of power grid disaster prevention, in particular to a vertical shock absorber and a method for determining the quality of a damping liquid medium in the vertical shock absorber. Background technique [0002] The large-span ultra-high-strength aluminum alloy stranded wire will generate breeze vibration under the action of continuous and stable wind, and the friction between the large-span wire strands will dissipate the energy of this breeze vibration. Moreover, when the transmission wire is in a continuous and stable wind area, this vertical oscillation will last for a long time, which will cause the strands of the wire to dissipate wind energy through friction between the strands for a long period of time . This friction between the wire strands will cause the wear of the wire, and in severe cases, it will cause the fracture of the worn position of the wire strands. The long-term micro-vibration and self-...
