Problems solved by technology

[0005] However, there are obvious disadvantages of interphase spacers
First of all, for the simultaneous galloping of two adjacent conductors, the phase-to-phase spacer is ineffective; secondly, when galloping occurs, the phase-to-phase spacer will force the two adjacent conductors to synchronize, so that the galloping energy of the conductors is more concentrated and strengthened, thereby causing damage to the transmission line and the tower. Greater harm; for compact lines, due to the triangular arrangement of the conductors, the interphase spacers are also subject to pressure and bending force while suppressing the tension generated by galloping. This compression and bending force can easily cause interphase spacers Damage to itself and the hardware connected to the wire

Embodiment Construction

[0026] The invention can be applied to high-voltage transmission lines in the range of 110kV to 1000kV.

[0027] Such as figure 1 As shown, the present invention includes a rigid rod body 3, an insulating shed 4, an adjustment plate 6 and a stay wire 7, the rigid rod body 3 is made of an inner epoxy resin glass drawing rod and an outer silicone rubber composite material layer, and the insulating shed shed 4 and silicone rubber composite material layer integrated structure.

[0028] The upper and lower ends of the rigid rod body 3 are respectively connected with a high-voltage end fitting 1 (connecting fitting) and an adjustment plate 6 , and the high-voltage end fitting 1 is used to connect the sub-spacers 9 . On the rigid rod body 3 between the high-voltage end fittings 1 and the adjusting plate 6, there are two end accessories: the upper pressure equalizing ring 2 and the lower pressure equalizing ring 13, and the upper pressure equalizing ring 2 and the lower pressure equa...

Abstract

The invention discloses a rigid phase-ground conductor spacer preventing gallop. The rigid phase-ground conductor spacer preventing the gallop comprises a rigid spacer body, an adjusting plate and a stay wire, wherein a connecting fitting and the adjusting plate are connected with the upper end and the lower end of the rigid spacer body respectively, two end portion accessories and insulating full skirts which are arranged between the two end portion accessories are arranged on the rigid spacer body and between the high-voltage end fitting and the adjusting plate in a sleeved mode, and the two ends of the stay wire are connected with the adjusting plate and the ground respectively. The rigid phase-ground conductor spacer preventing the gallop has the advantage of being capable of simultaneously restraining simultaneous gallop and asynchronous gallop of circuit wires.

Description

technical field [0001] The invention relates to the field of anti-dancing devices, in particular to a spacer bar. Background technique [0002] With the continuous expansion of the scale of the power grid and the deterioration of the natural environment, the galloping phenomenon of transmission lines and its hazards have gradually intensified, resulting in line tripping, disconnection, and in severe cases, the collapse of towers, causing major power grid accidents, and seriously threatening the normal operation of the power grid. [0003] At present, for the galloping of transmission lines, the main suppression measures are to install interphase spacers between the two-phase conductors, and use the interphase spacers to connect the galloping two-phase conductors, restrict each other during galloping, limit their respective galloping amplitudes, and at the same time ensure Insulation distance between phases to prevent mixed lines. [0004] The inter-phase spacer is mainly us...
