[0029] For a third embodiment, see Figure 5 , torsional electromagnetic damping anti-dance device, characterized in that the electromagnetic damping anti-dance device is mainly composed of an induction part and an excitation part, the induction part or the excitation part is disc-shaped, the two excitation parts are located on both sides of the induction part in the axial direction, and the three There are two air gaps between them. The induction component is mainly composed of a conductive plate 63 and a magnetic conductive plate 73. The conductive plate 63 is pasted and fixed on both sides of the magnetic conductive plate 73. The excitation component is mainly composed of a substrate 93, a permanent magnet 103 and a housing 83. , the magnetic poles of the permanent magnets 103 are arranged alternately along the circumferential direction N and S, and are fixed on the substrate 93 in turn. The magnetic poles of the permanent magnets 103 are in an axial magnetization structure ...

Abstract

The invention relates to a torsional electromagnetic damping power line anti-galloping device. The device mainly comprises a stator electromagnetic structure and a rotor electromagnetic structure. Thestator and the rotor are disc-shaped excitation parts or induction parts, the electromagnetic damping anti-galloping device is fixedly installed on a multi-split sub spacer clamped on a power line atpresent and is configured to absorb the galloping energy of the power line to generate damping to prevent the power line from galloping. The torsional electromagnetic damping anti-galloping device issimple in structure, easy to install, safe and reliable, low in cost and good in damping anti-galloping effect.

Description

technical field [0001] The invention relates to a torsion electromagnetic damping dance preventer, which belongs to the technical field of vibration control. Background technique [0002] Ice-covered galloping of overhead transmission line conductors is a form of disaster with high frequency, wide range of influence, and large losses. The frequent occurrence of galloping faults has seriously threatened the safe and stable operation of the power grid. In the face of increasingly complex meteorological environment factors, in order to build a strong national power grid and ensure the long-term safe and stable operation of the large power grid, safe, advanced, economical and reliable anti-galling theories and program measures are needed as a guarantee. Ice galloping on transmission lines has the characteristics of complex mechanism, difficult prevention and strong destructive power, and is an internationally recognized problem in the field of overhead transmission lines.
