Abstract
The invention relates to an anti-galloping spacer, which comprises a bracket and wire clamps, wherein the wire clamps are arranged on the end corner parts of the bracket and are connected with bundle conductors; the lower part of the middle part of the bracket is fixedly connected with a lambdoid pendulum device; the lambdoid pendulum device comprises a lambdoid frame plate and spherical pendulums; the top end of the lambdoid frame plate is fixedly connected to the bracket body on the lower part of the middle part of the bracket; and the spherical pendulums are fixedly connected to two bottom end heads of the lambdoid frame plate. In the spacer, the two ends of the pendulums are spherical, and the two pendulums are fixed on the left side and the right side of the bottoms of two pendulum frame plates through two screws respectively and are symmetrically distributed, so that galloping of the entire anti-galloping spacer can be effectively suppressed, the galloping amplitude can be reduced, and the harm of wire galloping can be reduced.
Description
Technical field
The present invention relates to the conductor spacer that a kind of superhigh pressure, UHV transmission line are used, particularly a kind of anti-bouncing spacer.
Background technology
At a distance, jumbo superhigh pressure, UHV transmission line, every phase conductor has adopted two, three, four, the six roots of sensation, eight and above oidiospore lead.In order to satisfy electric property, reduce the surface potential gradient, and under short-circuit conditions, unlikely generation electromagnetic force causes attract each other collision, whiplash between wire harness, though or cause the relative motion of moment, but accident can return to the design pitch state after eliminating, and needs to guarantee that bundle conductor wire harness sub-conductor spacing remains unchanged, and the conductor spacer of suitable specification and quantity is installed in suitable position in span for this reason.Lead spacer is installed, can also plays certain inhibitory action to subspan oscillation and aeolian vibration simultaneously.
In the practical application, adopt the conductor spacer bundle conductor often, conductor spacer self is often waved.
Waving is that wire icing forms a kind of low frequency that is produced behind the on-circular cross-section, the self-excited vibration of large amplitude, and amplitude generally below 12m, can cause gold utensil to damage and broken string, the serious meeting generation circuit accident of falling the tower.The inducement of conductor galloping can reduce wire icing (especially inhomogeneous icing), wind-force and three main aspects of line construction (comprising lead natural frequency, lead pattern, tension force, span, line alignment etc.) usually.Waving of transmission line brings great loss and harm once for the countries in the world circuit.Successively took place repeatedly to wave on China Hunan, Hubei, Anhui, Henan, North China and northeast and other places, and waved and relate to big leap and general circuit, the region relates to mountain area, hills and Plain; Meteorological condition relates to glaze, snow rime, and ice and snow is from several millimeters to tens millimeters.It involves a wide range of knowledge, and the kind complexity.
It is generally acknowledged that the probability that bundle conductor waves than single conductor is big.Solve the problem of waving of overhead transmission line with effective mode, research, exploitation is anti-, and to wave device be one of difficult problem that needs to be resolved hurrily.
At present, the anti-dancing device that adopts is varied both at home and abroad, comprising stockbridge damper, flow spoiler, inter-phase spacer, off resonance pendulum damper device, double pendulum anti-pendulum device etc., but owing to structural reason, they anti-waved effect and all do not reached the degree of line security of allowing, and we can say that its effect is unfavorable.
Summary of the invention
In view of the afore-mentioned and the deficiency of traditional conductor spacer, the invention provides and a kind ofly can effectively suppress to wave generation, reduce to wave amplitude, reduce the preformed bouncing-prevention damping spacing rod of the harm of conductor galloping.
Technical scheme of the present invention is: the present invention includes support and wire clamp, described wire clamp is located at the bracket end angular position, is used to connect bundle conductor, and the bottom in described support centre position is fixedly connected with the herringbone pendulum hookup; Described herringbone pendulum hookup comprises lambdoid deckle board and spherical pendulum, and the top of described herringbone deckle board is fixedly connected on the bottom support body in described support centre position, and described spherical pendulum is fixedly connected on two footing terminations of described herringbone deckle board.
Pendulum two among the present invention is spherical in shape, two pendulums are bolted to the left and right sides, two pendulum deckle board bottoms by two respectively, are symmetrically distributed, and make whole anti-dance conductor spacer can effectively suppress to wave generation, reduce to wave amplitude, reduce the harm of conductor galloping.
