Electric vibration damper applying shear thickening fluid

Abstract

The invention discloses an electric vibration damper applying shear thickening fluid, and relates to the technical field of transformer substation electric power guarantee equipment. The electric vibration damper comprises an electric stay cable, a hoop tube and an annular tube cylinder. The hoop tube and the annular tube cylinder are made of silica gel or rubber material. The annular tube cylinder has a shell structure which is internally provided with a cavity, and a center channel is arranged on the axial direction of the annular tube cylinder. The cavity is internally filled with shear thickening fluid. The side surface of the annular tube cylinder is provided with an elastic shrinkage expansion sealing cap which is communicated with the cavity. The hoop tube penetrates through the center channel of the annular tube cylinder and is fixedly connected with the internal wall of the center channel. The hoop tube sleeves the external part of the electric stay cable. A gap between the hoop tube and the electric stay wire is provided with an annular gluing cavity which is internally filled with flexible glue. Both of the hoop tube and the annular tube cylinder have a half body butting sealing structure. The beneficial effects of the electric vibration damper applying shear thickening fluid are that vibration of the electric stay wire is reduced by applying shear thickening fluid so that the effect is obvious and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of substation power protection devices. Background technique [0002] The overhead power lines are affected by meteorological conditions such as wind, ice, and low temperature, causing the lines to vibrate and dance. The vibration frequency is high and the amplitude is very small. The wind vibration causes the power cable to be repeatedly bent at the suspension point, causing material fatigue, and finally leads to broken strands and broken wires. The frequency of galloping is very low, but the amplitude is very large, which can easily cause phase-to-phase flashover, resulting in serious accidents such as line tripping, power failure or burning of wires. A shock hammer is just a length of iron rod. Because it is hung at the suspension point of the line tower pole, it can absorb or weaken the vibration energy on the line, change the swing frequency of the line, and prevent the line from vibrating or gallopin...

Problems solved by technology

The above two methods rely on responsive mechanical or electromechanical structures, which are complex and costly

[0004] For the design of the anti-vibration hammer, it can turn from the mechanical or electromechanical direction to the application of new functional materials, and use new materials to replace complex mechanical structures. At present, there is no application precedent in the electric power industry.
