Abstract
The invention relates to a multi-fission transmission lead torsional vibration swing-preventing device. More than two lead clamps for fixing transmission leads are evenly arranged on an annular spacer rod; a swing shaft can be rotatably arranged on the annular spacer rod through a bearing and the lead clamps are fixed on the swing shaft; and T-shaped swing rod is fixed at the bottom of the annular spacer rod and a balance weight ball and low-temperature anti-freezing fluid are held in an arc circular tube of the T-shaped swing rod. The torsion of overhead conductors can be prevented from rotating by self balance of round ball gravity; in addition, the multi-fission transmission lead torsional vibration swing-preventing device has the characteristics of simple structure, convenient installation and use and no need of frequent maintenance.
Description
Technical field
The present invention relates to the anti-device of waving that overhead transmission line is used, particularly mechanical type gravity self balancing device in order to stop transmission pressure to be waved.
Background technology
Conductor galloping is the key factor that threatens the overhead transmission line safe and stable operation, and one of the most serious country of disaster is waved by China, waves and can cause huge destruction to transmission line.Waving the reason of generation, is the aerial high voltage power transmission wire icing, because wire icing forms asymmetric circular section, causes conductor galloping thereby can bring out the self-excited vibration that lead produces a kind of low frequency, large amplitude under the effect of certain wind-force.If the initial stage at conductor galloping is not suppressed, the amplitude of then waving is increasing, gently then causes the flashover tripping operation, and is heavy then cause transmission line swinging cross, short circuit, broken string, major accident such as tower, cause large-area power-cuts, cause tremendous loss to national economy.
2008 in the snow disaster that China takes place, cause because of waving overhead transmission line conductor slippage, swinging cross, broken string and serious accident such as tower be exactly the strong clear proof of this harm.So, need a kind of not only economy, safety, environmental protection, but also can suppress waving of lead, reduce conductor galloping frequency and amplitude, and adapt to the anti-dancing device of different wind directions, with prevention with eliminate the generation of similar accident.
Summary of the invention
The purpose of this invention is to provide a kind of multi-fission transmission lead torsional vibration swing-preventing device simple in structure, easy to install.
The object of the present invention is achieved like this: a kind of multi-fission transmission lead torsional vibration swing-preventing device, more than two, with fixing uniform being arranged on the annular space rod of wire clamp of transmission pressure: swinging axle is arranged on the annular space rod rotationally through bearing, and wire clamp is fixed on the swinging axle; T type fork is fixed on annular space rod bottom, is loaded with weighted spherical ball and low temperature anti-icing fluid in the arc pipe of T type fork.
Above-mentioned configuration ball is counterweight iron ball or counterweight stainless steel ball.
Above-mentioned wire clamp is two, three, four, six or eight.
Divide on the ice coating wire more and produce when reversing to noncircular cross section when wind, wire clamp, wire clamp swinging axle and axle sleeve, annular space rod, circular arc pipe T type fork will reverse together.At this moment, low temperature anti-icing fluid in the circular arc pipe T type fork and iron sand ball counterweight will produce contrary reversing to counter-rotation, thereby disturb, suppress and consume the torsional oscillation energy that is produced in the conductor vibration, and final the inhibition excites the conductor galloping that produces because of torsional oscillation.
The invention has the beneficial effects as follows:
The present invention is simple in structure, cost is low, easy for installation, not only economic, safe but also environmental protection, does not need frequent maintaining.Certain economic benefits of the present invention and social benefit.
Description of drawings
Fig. 1 is the structural representation (front view) of one embodiment of the present of invention (conductors on quad bundled);
Fig. 2 is the stereogram of Fig. 1.
Embodiment
Fig. 1 Fig. 2 illustrates, and the present invention is made up of wire clamp 1, (wire clamp) swinging axle 2 (comprising bearing), annular space rod 3, (arc pipe) T type fork 4, low temperature anti-icing fluid 5 and weighted spherical ball 6.
More than two, with fixing wire clamp 1 uniform being arranged on the annular space rod 3 of transmission pressure 7: swinging axle 2 is arranged on the annular space rod 3 rotationally through bearing, and wire clamp 1 is fixed on the swinging axle 2; T type fork 4 is fixed on annular space rod bottom, is loaded with weighted spherical ball 6 and low temperature anti-icing fluid 5 (be that bearing outer ring is fixed on the annular space rod, swinging axle is fixed on the bearing inner race) in the arc pipe of T type fork.Corresponding to two divisions, tripartition, quadripartion, six division or eight bundle conductors, wire clamp is respectively two, three, four, six or eight.In general, wire clamp is arranged on rotationally on the annular space rod and gets final product.As, can not adopt bearing (just frictional resistance is bigger) or other existing mode.
Weighted spherical ball 6 is counterweight iron ball or counterweight stainless steel ball.When wind on many divisions icing noncircular cross section lead and produce when reversing, annular space rod and circular arc pipe T type fork are along with rotation.At this moment, anti-icing fluid in the circular arc T type fork and iron sand ball counterweight will and produce contrary reversing to contrary direction motion, suppress and will consume the torsional oscillation energy that is produced in the conductor vibration, thereby suppress to excite the conductor galloping that produces because of torsional oscillation.This anti-dance device is applicable to various bundle conductors such as two divisions, tripartition, quadripartion, six divisions and eight divisions.
This device can utilize steel to be welded.T type fork can adopt pitch circle Guan Yuyi joint bend pipe to be welded, and the degree of crook of bend pipe (being radius of curvature) can be suitably big, and simultaneously, the bend pipe wall should be smooth, is beneficial to the slip of weighted spherical ball.The section configuration of conductor spacer can be the annular of rectangle or parallelogram or similar rectangle (relative two limits are for camber line, and both sides are straight line in addition).Wire clamp is hinged on the conductor spacer.
