Problems solved by technology

However, the inventor found that the anti-galling and vibration reduction control used on transmission lines in actual engineering is mostly passive control. Considering the influence of various factors, passive control has certain limitations, lacks self-regulation function, and suppresses the amplitude of vibration. Limited, unable to meet the requirements of UHV, long-distance and long-span power transmission in the current power industry

Abstract

The invention discloses a swing suppression energy dissipation device. The swing suppression energy dissipation device comprises a connection part and an energy dissipation part. The left and right sides of the energy dissipation part are each provided with an energy dissipation cylinder. The left and right energy dissipation cylinders belong to airtight cylindrical tubes. The energy dissipation cylinders contain magneto-rheological fluid. A magnet exciting coil is coiled on the periphery of each cylindrical tube and connected with a piezoelectric unit. The cylindrical tubes on the two sides are each internally provided with a rolling wheel. A gear is arranged between the two cylindrical tubes. The rolling wheels and the gear are fixed through a connecting shaft and can rotate coaxially. The connection part is composed of a hollow box-type tube in the middle and toothed plates on the left and right sides. Piezoelectric power generation units are arranged at the bottom end of the hollowbox-type tube and in the middle position of the interior of a main body of the energy dissipation part correspondingly. The two ends of each piezoelectric power generation unit are provided with pressure sensors. The box-type tube is internally provided with a mass body. The mass body is connected with the two ends of the box-type tube through springs. The toothed plates of the connection part are engaged with the gear of the energy dissipation part. The periphery of the whole energy dissipation part is totally enclosed.

Description

technical field [0001] The invention relates to a novel anti-galling device, in particular to the technology of suppressing galloping and energy consumption of a power transmission line, which mainly controls the galloping phenomenon of the power transmission line under the action of wind load. Background technique [0002] Galloping of transmission lines will occur when the surrounding ice is covered and side wind acts. The galloping of transmission lines is a problem that must be paid attention to in the process of power transmission and needs to be solved seriously, because galloping of transmission lines will cause various hazards. For example, it will cause the breakage of the wire, damage the restraint device at the connection part of the wire, make the connecting bolt fall off, even cause the toppling of the transmission tower, and cause a serious electric safety accident. [0003] Aiming at the problem of galloping of transmission lines, various technical measures ha...
