Abstract

The invention discloses an energy-feed composite anti-galloping energy dissipation spacer comprising a body, wherein a cavity is formed inside the body; an excitation coil is mounted on the inner sideof the body; a metal clamp is arranged on the outer side of the body; a first insulating layer is arranged between the excitation coil and the body for insulation; a ring barrel filled with a magnetorheological fluid is arranged in the inner ring of the excitation coil; a metal ball which can roll in the ring barrel is arranged in the ring barrel; a plurality of piezoelectric generating units areinstalled at intervals on the inner ring of the ring barrel along the circumferential direction; pressure sensors is disposed at the two ends of each piezoelectric generating unit; the piezoelectricgenerating unit is connected in series with an electric energy extraction and storage unit, a controller and the excitation coil to form a closed loop; the inner ring of each piezoelectric generatingunit is provided with a second insulating layer; and an electromagnetic particle vibration absorption body is disposed on the inner side of the second insulating layer.

Description

technical field [0001] The invention relates to vibration reduction technology for power equipment and transmission lines, in particular to an energy-feeding composite type anti-galling energy-consuming spacer. Background technique [0002] With the rapid development of economy and industry, my country's social development has rapidly increased the demand for electric energy, and electric energy has become a necessity for social development. At present, the conductors in the transmission lines are mostly split, and when the conductors are unevenly covered with ice along the circumference and subjected to lateral winds, low-frequency, large-scale self-excited vibrations occur, that is, transmission line galloping. Line galloping will cause line tripping, which will cause electrical failure. In addition, it will cause damage to fittings, insulators, and jumpers, broken wires, broken wires, damage to tower materials and foundations, and serious mechanical damage such as loose b...
