Description
Technical field
The utility model relates to the conductor spacer that a kind of superhigh pressure, UHV transmission line are used, the particularly preformed anti-skidding anti-damping conductor spacer of waving.
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.
At present, the conductor spacer of domestic typing mainly contains three kinds: (1) bolt type conductor spacer: the conductor spacer wire clamp adopts bolted, and utilizes bolt to obtain reliable grip.Therefore the size of bolt torsional moment is just particularly important, crosses the conference damage wires, too small then wire clamp grip deficiency.In order to obtain effectively constant grip, and get rid of the creep of lead and the influence of plastic deformation, utilize torque wrench to control the bolt torsional moment when mounted usually; In addition, bolt looseness then is the conductor spacer cause faults.(2) pin type wire clamp conductor spacer: pin type wire clamp conductor spacer is meant that the rubber that wire clamp is embedded in excellent conductive performance contains lead, when rubber is compressed to the limit, the insertion bearing pin is fixed, and utilizes the elastic force of rubber that lead is compressed, and can effectively avoid the problem of bolt looseness.But the installation of this conductor spacer needs specific purpose tool, is not easy to construction.(3) ball strand formula conductor spacer: the wire clamp of ball strand conductor spacer is generally made by aluminium alloy, is tie point with the steel ball of ball-and-socket and strut.Tangle bulb and stay pipe adopts the aluminium alloy rivet, and rivet and riveted joint place are easy to generate wearing and tearing and cause the accident.By bolt gland is locked and to realize that ball rod is connected with wire clamp.
Yet because lead is among the open-air natural environment, temperature changes with seasonal variations, and the cold phenomenon of the heat expansion of lead can make the diameter of lead change to some extent, thereby causes conductor spacer that holding of lead puted forth effort to be subjected to certain influence; Again because lead also has by a relatively large margin variation at run duration because of diversified factor causes its operating temperature thereupon, the action effect of this variations in temperature is similar to thermal cycle, and final also possibility cause wire clamp that holding of lead puted forth effort to descend because of causing bolt torque to descend.Conductor spacer is held the following general who has surrendered who puts forth effort to lead and may directly be had influence on conductor spacer and slippage may occur and scurry the position; cause the best position of conductor spacer off-design thus; thereby do not have should the producing effect of fixing cord, protection circuit of design; even may bring new danger vibration, stress to increase to lead in certain residing position of particular moment conductor spacer; even cause the lead fatigue rate to be accelerated, and then cause serious accident and loss such as circuit damage.
In addition, because traditional conductor spacer has adopted chuck formula structure, conductor spacer is to the clamping of lead and holding by bolt and nut group, fastening wire clamp and gland and realizing, the stress surface of lead is confined within the width of chuck, be generally tens millimeters, stress area is too small, exists because of producing stress to concentrate the safe addiction of damage wires to suffer from.The chuck formula structure of tradition conductor spacer, need the wire clamp clamp be fixed on the lead by bolt and nut, owing to used bolt and nut, so need strict control mounting torque when installing, otherwise, thereby perhaps cause conductor spacer to cause the suitable line grip of conductor spacer not up to standard to the clamping of lead is loose partially because of mounting torque is less than normal, perhaps cause conductor spacer that the clamping tension of lead is caused the damage that thereby the excessive compression of lead is damaged lead or interval self, have the hidden danger of secure context because of mounting torque is excessive.The mode that fixes by bolt and nut of tradition conductor spacer is installed on the lead, erection stage, and the fitting operation personnel need be with corresponding instrument (as: torque spanner etc.) to climb to carry out work high above the ground on the tower, and homework burden is bigger, inefficiency; Acceptance phase, for accurately check each wire clamp even each bolt mounting torque whether meet the requirements, the technical staff has to go up shaft tower by the base climbing, one by one the mounting torque of conductor spacer is measured, workload is big, the working strength height, work difficulty is big, and is dangerous high.If operating personnel are careless in the installation process, bolt and nut may fall from shaft tower, gently then causes bolt and nut to fall into thick grass or mountain valley and lose, and is heavy then hit the staff who assists under the tower and cause security incident.
Also have, 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.
