Description

The crimping sleeve that transmission and distribution line is used
Technical field
The present invention relates to a kind of electric armour clamp, more particularly, relate to a kind of crimping sleeve that the high-low voltage transmission-distribution line road is used that is mainly used in, be a kind of can with the crimping sleeve of the C font of conductor compression jointing all-in-one-piece copper, aluminium or other metal material.
Background technology
Crimping sleeve is commonly called as " wire clamp ", is a kind of electric armour clamp commonly used, divides " tension-type wire clamp " and " non-tension-type wire clamp " two classes, and " non-tension-type wire clamp " is divided into " bolt lock type " again and presses " crimp type " two kinds.
Domestic a large amount of uses at present be " parallel groove clamp " of " bolt lock type ", this kind wire clamp is two ducts of processing and two or more bolt hole on thick aluminium flat board, again with two pairs of ditch aluminium flakes of two or more bolt lockings, to finish continuing of lead and lead, the contact area of wire clamp and lead is little, and contact resistance is bigger, temperature rise is higher, the electric property instability is so continuing of everywhere lead and lead needs to use two " parallel groove clamp ".
Because electric power can't store, for electric power can effectively be used, and the society need for electricity is ardent, " power failure operation " will cause the loss of the energy and to the inconvenience of bringing of society life, and " live line working " is trend and the irresistible trend got rid of of electric utility line construction and accident from now on.
When " live line working ",, whenever have only the bolt more than two or two need use " wrench " instrument lock nut because of each place of continuing of parallel groove clamp needs to use two, constructional difficulties degree height, the constructor is easier to take place electric shock accidents.
At the present crimp type C shape wire clamp that uses of the U.S. and Taiwan, its structure is the column that the cross section is the C word shape, and the surfaces externally and internally of wire clamp is a smooth surface.When this wire clamp used in " live line working ", because of each place of continuing only uses one, though " bolt lock type " wire clamp is low for its cost, and so that " hydraulic tongs " instrument crimping of insulated handle to be arranged, it was simple and easy to construct, and the constructor electric shock accidents can not take place.But C shape crimping sleeve or jointing clamp that the Taiwan Ju Ze company and the U.S. produce now all are U.S.'s specifications, and at home and abroad market is rather popular, and structurally also there is following shortcoming in this wire clamp:

04. existing C shape copper, aluminium jointing clamp because of can't effectively closely filling up the duct space after the crimping, and then cause that pulling force is little, resistance big, temperature rise, cause easily that the folder inside conductor gets loose, the wire clamp scaling loss, cause the feeder line fault accident.
05. existing C shape copper, aluminium jointing clamp can't effectively closely be filled up because of duct space after the crimping, cause aqueous vapor or dust to enter the duct space, can produce the corrosion of wire clamp and lead, cause power circuit generation broken string accident.
06. existing C shape copper, aluminium jointing clamp, when inserting conductor compression jointing, the afterbody of matrix two ends duct, can't effectively fit tightly along lead, and be lead profile lining, and cause that the duct and the lead of wire clamp entity presents pancake after the crimping, do not meet wire clamp crimping requirement.
07. existing C shape copper, aluminium jointing clamp, according to the above, duct and the lead of wire clamp crimping entity are pancake, and lead more easily gets loose, and the diffusion of the line thigh of lead, reduce protective layer, corrode easily and break generation feeder line fault accident.
08. existing U.S. rule C shape copper, aluminium jointing clamp, according to the above, wire clamp crimping entity, the bottleneck of pulling force requirement standard is difficult to be broken through.Its maximum crimping lead only is equivalent to 107 couples of 107mm 2, its pulling force after continuing of wire clamp that surpasses this specification can not reach 454 kilograms of standard values; So, have inconvenience for continuing of copper, the big line of aluminum conductor footpath.
09. existing U.S. rule C shape aluminium jointing clamp, the big line of crimping footpath be to the specification in big line footpath, its length is long, crimping often, the wire clamp entity after the crimping presents curved shape, do not meet wire clamp crimping requirement.
10. existing U.S. rule C shape aluminium jointing clamp; in order to improve the resistance to tension of wire clamp; length by the lengthening wire clamp realizes; therefore the crimping number of times increases; the problem of bringing thus is that the wire clamp entity after the crimping is curved shape; when power circuit " live line working "; its " safe insulation rubber tube of the closed shape of opening "; can't penetrate lining; if penetrate reluctantly; crooked live part can expose outside the pipe, forms the potential work safety crisis that electric shock accidents takes place for " live line working " difficulty and live line working person.
11. existing C shape aluminium jointing clamp, wire clamp entity after the crimping presents curved shape, when angle of bend is big, cause is the temperature difference and spike off peak load day and night, cause and expand with heat and contract with cold, the wire clamp that accumulates over a long period can cause the lead that continues to get loose or breaks in knee fracture, produces the power circuit power outage, and loss and reduce the power supply income increases electric power.
12. existing C shape copper, aluminium jointing clamp, duct and lead are pancake after the wire clamp crimping, the lead that produces gets loose, corrosion, broken string, the feeder line fault that causes, can cause " owing to turn round mutually ", scaling loss user's facility cause damage for user or Utilities Electric Co., and cause the reparations dispute between user and the Utilities Electric Co..
