Description
Technical field
The utility model relates to a kind of conductor spacer bundle conductor syndeton.
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, and too small then wire clamp grip is not enough.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 processed 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.Through 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 receive certain influence; Again because lead also has variation by a relatively large margin 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 possibly directly had influence on conductor spacer and slippage possibly 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 maybe be in certain residing position of particular moment conductor spacer bring new danger vibration, stress to increase to lead, 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 through bolt and nut group, fastening wire clamp and gland and realizing, the stress surface of lead is confined within the width of chuck, is 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 through 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 through 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 each wire clamp of inspection 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, and working strength is high; 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.
The utility model content
In view of the afore-mentioned and the deficiency of traditional conductor spacer, the utility model provides the conductor spacer bundle conductor syndeton that a kind of structure is reasonable more, reliability is higher, fatigue resistance good, damping is good, non-skid property is good, easy for installation.
The technical scheme of the utility model is: comprise wire clamp; Said wire clamp is located at the bracket end angular position, is used to connect bundle conductor; Said wire clamp also comprises preformed armor rods; The head end position that said wire clamp is used to connect bundle conductor is hook-type, and the back side of said hook-type is provided with the location structure that is used to locate said preformed armor rods.
The back side of said hook-type is provided with the location structure that is used to locate said preformed armor rods and is at least two round table-like pins, and said at least two round table-like pins are in the circumferential laying of the axial line of said hook-type.
The back side of said hook-type is provided with the location structure that is used to locate said preformed armor rods in the circumferential protrusion of the axial line of said hook-type and the hollow arcuate convexity at the said hook-type back side.
The lead holding tank inner surface of said hook is provided with the elastic anti-slip neonychium; Be provided with in the middle of the extrados of said neonychium and protruding button two ends are installed are upwards rolled and be " mountain " font; And extrados and lead holding tank inner surface are fitted, and the intrados of said neonychium and wire diameter size are complementary; The protruding button of the installation of said neonychium is bonded in lead holding tank inner surface with the also chimeric back of installation with seccotine.
The mode of the connection bundle conductor of the utility model is improved to the preformed armor rods connected mode by position limiting structure, can free-handly install, and is easy for installation, good reliability, and installation quality is easy to control, and this product can keep its normal technical performance in the whole service life span; Because the characteristic of preformed armor rods makes its loosening problem that does not only have bolt, also has the loosening ability that compensation takes place owing to lead creep, plastic deformation and vibration.
