Description
Technical field
The present invention relates to a kind of aerial high-voltage bundle conductor protection gold utensil, specifically relate to a kind of preformed, revolution wire clamp formula conductor spacer.
Background technology
When built on stilts EHV transmission, to compare with solid conductor, bundle conductor can make that the inductance of power transmission line reduces, electric capacity increases, and its wave impedance to alternating current is reduced, and improves the ability to transmit electricity of circuit, so generally adopt bundle conductor.But; bundle conductor is waved through regular meeting's generation under the wind-force effect; this waving can produce excessive tension force to lead; make lead owing to fatigue accumulation and short-term, go offline; when serious; this phenomenon of waving can be to causing mechanical injuries as iron tower member, insulator string one class transmission facility, and What is more, waves to cause iron tower to collapse.Therefore, take effective and efficient manner to prevent that waving of transmission line from being problem demanding prompt solution.
The analysis showed that the generation reason that high pressure overhead power line is waved phenomenon has: the inhomogeneous icing of certain wind speed and direction and lead.Wherein the inhomogeneous icing of lead is an essential condition of transmission line galloping, therefore stops lead to produce inhomogeneous icing, or effectively reduces the degree of the inhomogeneous icing of lead, and is very favourable to the control transmission line galloping.In addition, when wind-force is very strong, can cause the lead subspan oscillation, subspan oscillation both can directly cause lead tired and destroy, more may make securing member loosening and make the lead wearing and tearing indirectly.Therefore to have the protection gold utensil that prevents conductor galloping and two kinds of anti-dance performances of subspan oscillation be the task of top priority in exploitation.
The protection gold utensil that uses on China's aerial high-voltage power transmission line has following two kinds of forms at present: (1) wire clamp is fixed wire clamps spacer rod type anti-dance device, fixed wire clamps spacer rod type anti-dance device is suppressing aspect transmission line aeolian vibration and the subspan oscillation certain effect is arranged, but this anti-dance device is unfavorable for the even icing of lead.(2) wire clamp is a rotary type wire clamp spacer rod type anti-dance device, rotary type wire clamp spacer rod type anti-dance device can reduce the degree of the inhomogeneous icing of lead, but the while has also been reduced the torsional rigidity of the integral body of bundle conductor, the upset of the lead of may causing a split under certain wind-force excitation.
Summary of the invention
In view of the above problems, the object of the present invention is to provide a kind of lead that can effectively stop to produce inhomogeneous icing, or effectively reduce the inhomogeneous icing degree of lead, thus prevent transmission line galloping, reduce preformed, the revolution wire clamp formula conductor spacer of subspan oscillation to the lead infringement.
Above-mentioned purpose of the present invention realizes by the following technical solutions:
A kind of preformed, revolution wire clamp formula conductor spacer provided by the invention, comprise: preformed armor rods, rotary type wire clamp, preformed wire clamp and conductor spacer body, its improvements are: described rotary type wire clamp and preformed wire clamp are the both sides that symmetry axis is installed in the conductor spacer body with the perpendicular bisector of conductor spacer body, described rotary type wire clamp clamps sub-conductor, described preformed armor rods is wrapped on the sub-conductor, and described preformed wire clamp clamps the sub-conductor that is wound with preformed armor rods.
Preferably preformed, revolution wire clamp formula conductor spacer of the present invention, described rotary type wire clamp and preformed wire clamp are symmetrical arranged or are provided with at interval.
In one preferably preformed again, the revolution wire clamp formula conductor spacer provided by the invention, described preformed wire clamp comprises preformed chuck of the wire clamp that is used for the clamping sub-conductor and connector, described connector is located at the lower end of the preformed chuck of wire clamp, the both sides of the preformed chuck of described wire clamp are provided with annular hanger, the lower end of described connector is arranged with the earhole that is used to connect the conductor spacer body, after the preformed chuck of described wire clamp clamps the sub-conductor that is wound with pre-wire, the two ends of described pre-wire are fixed on the annular hanger of the preformed chuck of wire clamp both sides.
In one preferably preformed again, the revolution wire clamp formula conductor spacer provided by the invention, the preformed chuck of described wire clamp be a half round post, and the arc place is installed with a rubber lining tile within it.
In one preferably preformed again, the revolution wire clamp formula conductor spacer provided by the invention, described rotary type wire clamp and preformed wire clamp all are fixedly connected on the conductor spacer body by set bolt.
With the prior art ratio, technical scheme provided by the invention has following beneficial effect:
In preformed, the revolution wire clamp formula conductor spacer provided by the invention, be provided with the rotary type wire clamp, this wire clamp can wind perpendicular to the conductor length direction when being subjected to the wind excitation and rotate, such rotation has suppressed to form freezing or accumulated snow of constant shapes on lead, effectively reduce the degree of the inhomogeneous icing of lead, thereby reduce the amplitude of waving of lead, change into the track of conductor galloping non-circular; Preformed armor rods is with the mode of the preformed chuck fixing cord of wire clamp, make wind on the lead energy that shakes pass to the preformed chuck of wire clamp to greatest extent by preformed armor rods, absorb oscillation energy by the rubber lining tile in this process, therefore preformed armor rods can effectively suppress the lead subspan oscillation, the subspan oscillation that minimizing high wind causes is to the damage of lead, in addition, the preformed chuck of wire clamp is taked half-cylindrical wire clamp head, has alleviated the total quality of conductor spacer.Therefore technical scheme provided by the invention is the anti-dancing device of a kind of composite type, and is simple in structure, easy for installation, safeguards easily, cheap, in light weight, applicable to the bundle conductor of arbitrary form.
