Description
Technical field
The present invention relates to a kind of crimping sleeve that the high-low voltage transmission-distribution line road is used that is mainly used in, be commonly called as wire clamp, especially a kind of can be with wire clamp and conductor compression jointing all-in-one-piece copper, aluminium or other metal material drive 8 shapes, H shape wire clamp.
Background technology
Crimping sleeve is commonly called as wire clamp, is a kind of electric armour clamp commonly used, is divided into " tension-type wire clamp " and " non-tension-type wire clamp " two classes, and " non-tension-type wire clamp " is divided into " bolt lock type " and " crimp type " two kinds again, and crimp type is divided into out two kinds of 8 shapes and H shapes again.
Domestic a large amount of uses at present be " parallel groove clamp " of " bolt lock type ", this kind wire clamp is to make two ducts and two or more bolt hole on thick aluminium flat board, finish continuing of lead and lead with the pressure of two or more pairs of ditch aluminium flakes and nut clamping screw again, the contact area of wire clamp and lead is little, adapting electric voltage is bigger, and temperature rise is higher, and electric property is unstable, 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, and " power failure operation " causes the inconvenience of the loss of the energy and society life, and " live line working " is the trend and the irresistible trend of electric utility line construction and accident maintenance 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.
" live line working " used and opened 8 shapes or H shape metal material jointing clamp, because of each place of continuing only uses one, " bolt lock type " wire clamp is low for its cost, and so that " hydraulic tongs " instrument crimping of insulated handle to be arranged, it is simple and easy to construct, and the constructor electric shock accidents can not take place.Surpass the wire clamp of this specification, the pulling force after it continues can not reach standard value.
But in the prior art, wherein, the Taiwan Ju Ze company and the U.S. produce now opens 8 shapes, H shape crimping sleeve or jointing clamp, is U.S.'s specification, and at home and abroad market is rather popular, but structurally also there is following shortcoming in this wire clamp:
1. the existing 8 shape wire clamps of opening, copper only have 3 kinds of specifications, and its maximum is equivalent to 60,100, and-60,100mm
2, above the wire clamp of this specification, the pulling force after it continues can not reach standard value 454kg; The wire clamp of aluminium matter is the resistance to tension after the length by the lengthening wire clamp improves it and continues, but because the increase of length causes the increase of crimping number of times, thereby is difficult to guarantee the linearity and the cylindricity of wire clamp after the crimping, and then causes the decline of the quality that continues.Though plurality of specifications is arranged, all be U.S.'s specification, be not suitable for Chinese metric system lead and use, also do not open 8 shape copper, aluminium jointing clamp at present at Chinese metric system lead design.
2. existing open 8 shape copper, aluminium jointing clamp, same specification, the little line of crimping footpath to little line footpath lead after, can't effectively closely fill up because of the duct space, cause the pulling force, resistance, temperature rise etc. of wire clamp to be difficult to meet international standard.Referring to table one, for example: 14,38-14, the wire clamp of 38 specifications, when the lead, 14 of the lead of crimping 14-14,22-14 ,-38 lead, its value of thrust all can not reach standard value, and just can reach standard value when the lead of the big line warp of crimping.
3. existing 8 shape copper, the aluminium jointing clamp opened because of can't effectively closely filling up the duct space after the crimping, and then causes that pulling force is little, resistance big, temperature rise, causes easily that the wire clamp inside conductor gets loose, the wire clamp scaling loss, causes the feeder line fault accident.
4. have now and open 8 shape copper, aluminium jointing clamp, can't effectively closely fill up, 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 because of duct space after the crimping.
5. existing open 8 shape copper, aluminium jointing clamp, when inserting conductor compression jointing, the afterbody of matrix two ends duct can't be effectively fit tightly and is the lining of lead profile along lead, the crooked again interlayer outside that is involved in the middle of the matrix.Cause that the duct and the lead of wire clamp entity all presents pancake after the crimping, do not meet wire clamp crimping requirement.
6. existing 8 shape copper, the aluminium jointing clamp opened, according to the above, wire clamp crimping entity, duct and lead are pancake, and lead more easily gets loose, and the diffusion of the line thigh of lead, reduces protective layer, corrodes easily and breaks generation feeder line fault accident.
7. existing 8 shape copper, the aluminium jointing clamp opened, according to the above, wire clamp crimping entity, pulling force require the bottleneck of standard to break through than difficult.The copper 8 shape jointing clamps of opening of the U.S., maximum only is equivalent to 100 couples of 100mm
2The line footpath, its maximum is equivalent to 60,100, and-60,100mm
2, above the wire clamp of this specification, the pulling force after it continues can not reach standard value 454kg; So its specification only has 3 kinds,, there is inconvenience to continuing of the big line of what copper conductor footpath.
8. existing open 8 shape aluminium jointing clamps, though that the specification of the U.S. has is multiple, the wire clamp that big line directly uses, its length is long, crimping often, the wire clamp entity after the crimping presents curved shape, does not meet wire clamp crimping requirement.
9. the existing 8 shape aluminium jointing clamps of opening; in order to improve the pulling force of wire clamp; length by the lengthening wire clamp realizes, so the crimping number of times increases, and 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.
10. the existing 8 shape aluminium jointing clamps of opening, 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, causes and expands with heat and contract with cold, and accumulates over a long period, wire clamp can rupture at Qu Jiaochu, cause the lead that continues to get loose or break, produce the power circuit power outage, loss and reduce the power supply income increases electric power.
11. existing 8 shape copper, the aluminium jointing clamp opened, duct and lead are pancake after the wire clamp crimping, the lead that produces gets loose, the burn into 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..
In the prior art, wherein, the H-shaped crimped aluminium clip that the Taiwan Ju Ze company and the U.S. produce now all is U.S.'s specification, and is rather popular on the market at home and abroad, but this wire clamp is plate shaped cover plate, also has following shortcoming on the structure:
1. the H shape jointing clamp of existing plate shaped cover plate is U.S.'s specification, and the crimping that can not be fit to the metric system aluminum conductor of China's use fully continues.The steel-cored aluminium cable that China uses now, same nominal area because of using steel core linear diameter difference, causes the steel-cored aluminium cable diameter difference of same nominal area.So the H shape jointing clamp of existing plate shaped cover plate can't satisfy the demand that Chinese steel-cored aluminium cable crimping continues fully.At present also not at China's Aluminum lead 16~240mm
2The H shape jointing clamp of the plate shaped cover plate of design, (contain compression shape lining aluminum steel if need at the China's Aluminum lead, naked aluminium stranded conductor, steel-cored aluminium cable) the H shape jointing clamp of the plate shaped cover plate of redesign, for guaranteeing the H shape jointing clamp of same specification, the crimping minimum is to minimum, and maximum is to the lead driving fit fully of maximum, its pulling force, resistance, temperature rise can both meet international standard, then 16~240mm
2Need to use following 21 kinds of specifications to satisfy.
2. though the H shape jointing clamp of existing plate shaped cover plate is U.S.'s specification, but the aluminum conductor of same specification crimping U.S. specification, when also having the aluminum conductor minimum to the crimping of minimum line footpath, because of plate shaped cover plate gos deep into duct, can't effectively fill up the duct space, cause pulling force, resistance, temperature rise etc. to be difficult to meet international standard, cause use after, the failure accident of power circuit takes place.
3. the H shape jointing clamp of existing plate shaped cover plate, same specification crimping aluminum conductor maximum are during to the max line footpath, and plate shaped cover plate just in time is covered and is connected H shape jointing clamp body two ends, forms the thin seam of two place's fragilities, and be more perishable and come off.
4. the H shape jointing clamp of existing plate shaped cover plate, when often needing to do once above wire clamp crimping, cover plate often occurs from the crimping fracture first time, the crimping that the has a strong impact on aluminum conductor quality that continues.
5. have the H shape jointing clamp of plate shaped cover plate now, before conductor compression jointing, cover plate need do that 45 degree are gone up folding so that when inserting lead, toward up rolling over 90 degree, easily cause cover plate fracture because plate shaped cover plate does not have the design of interior stopping groove, through last folding lead is inserted duct and under fold to after the end prevents that lead from skidding off duct, easy breaking releasing, so that can't crimping.
6. above-mentioned the 5th situation, the easiest generation when live line working is because the operator hand is worn the leather glove that rubber gloves add protection; point very dumb; through regular meeting plate shaped cover plate is fractureed, so that during construction cost, especially often occur in unskilled operator.

11. the crimping sleeve that this transmission and distribution line is used, because of at random locking depression being arranged or/and the design setting of lock projection at random, and the locking rod is arranged or/and the design setting of the locking ditch of oblique line shape or zigzag shape, its key is to place the locking depression of wire clamp or/and lock projection, or the locking rod is or/and the locking ditch has stress equilibrium and interlocking after inserting conductor compression jointing, therefore, wire clamp and lead can fit tightly, the pulling force that wire clamp after the crimping can bear increases, rule rule of thumb: pulling force is big, temperature rise, resistance can be little, thereby it is little to reach resistance, the Expected Results that temperature rise is low.Do not have the locking rod and be provided with the design of locking ditch, maximum to the max line footpath, pulling force can conformance with standard, and maximum value of thrust is unreliable to below the maximum, and minimum to the minimum line footpath, general difficulty meets the pulling force standard.Through result of the test, wire clamp has locking rod and the design of locking ditch to be provided with, and its pulling force is on average greater than the design setting of not having locking rod and/or locking ditch: 1) maximum max line is directly improved more than 1/4 do not waited.2) maximum directly following raising does not wait more than 1/3 to max line, and the more little gap in line footpath is big more.
Referring to table 2, for originally opening the pulling experiment parameter after 8 shape copper, aluminium jointing clamp are set up locking rod and locking ditch, no matter wire clamp for same specification is big line directly directly all can reach and be higher than pulling force to the pulling force behind the conductor compression jointing in little line footpath to little line footpath or little line to big line footpath, big line footpath standard value as can be seen from experimental data, and there is not same specification, the little line of crimping is directly to behind the lead of little line footpath, can't effectively closely fill up because of the duct space, pulling force, resistance, temperature rise that causes wire clamp etc. is difficult to meet international standard (referring to table 1).And wire clamp after the crimping and lead be shape linearly, can flexural deformation, meet wire clamp crimping requirement.
13. the present invention opens 8 shape copper, aluminium or other metal material jointing clamp developer, be engaged in electric utility work all one's life, has again to produce the practice working experience that U.S. rule are opened 8 shape copper, aluminium jointing clamp for many years.Novel 8 shape copper, the aluminium jointing clamp opened is through the qualification test result, and pulling force, resistance, temperature condition all are better than existing U.S. specification and open 8 shape copper, aluminium jointing clamp.For continuing of lead have construction simple and easy, durable in use, small and exquisite pragmatic, save resource, energy savings, raising job security, reduce line accident and line loss, enhancing power supply reliability, increase the multiple advantage and the benefit of power supply income.
14. originally open the jointing clamp of 8 shape copper, aluminium or other metal material, because of the locking depression being arranged or/and the design of lock projection, the locking rod is perhaps arranged or/and the design setting of locking ditch, remove and use on the high-low voltage transmission-distribution line road, can prevent outside the feeder line fault accident, be used in indoor circuit and more can avoid causing the disaster of fire or the line of entering house to drop, common people's electric shock accidents takes place because of the joint generation spark that gets loose.
Compare with tradition " parallel groove clamp " 15. originally open the jointing clamp of 8 shape copper, aluminium or other metal material, following obvious advantage arranged:
(1) the every place lead place that continues, wire clamp needn't use two, only needs to use once, can save half national resources.
(2) wire clamp is in light weight, and pulling force, resistance, temperature condition are good, can save national resources.
(3) can prevent the electric power line failure power outage, reduce the loss of supply.
(4) crimping is quick, favourable feeder line fault repairing, power supply ahead of time.Lower society's injury that " power outage " causes, especially traffic signals, smelting furnace and high-tech industry are the most serious.
(5) wire clamp is simple in structure and be integrally formed, and " producing quality " guarantees, can expect.
(6) wire clamp uses the crimping tool crimping, and " crimping quality " guarantees, can expect.
(7) " live line working " to wear insulated tube easy, hot line clamp can not expose, and can avoid electric shock accidents.
(8) the wire clamp lead that fully is covered after the crimping, lead can not corrode, and power supply reliability is good.
(9) duct of aluminum steel folder scribbles anti-oxygen protection oil, has anti-oxygen concurrently and strengthens electric conductivity.
(10) easy to carry, can alleviate workmen's load, increase work capacity.
In sum, of the present invention the crimping sleeve that transmission and distribution line is used, it opens 8 shape jointing clamps via locking depression at random, lock projection at random; The setting of the locking ditch of locking rod, oblique line shape or zigzag shape has reduced the compression of matrix inner surface and the tension stress of outer surface, and has been integrally formed, continue as lead and lead and to be to use " Press Plier " instrument, wire clamp and lead are pressed into one, and because of wire clamp and the whole closely pressing of lead, adapting electric voltage is little, temperature rise is low, electric property is extremely stable, so continuing of everywhere lead and lead only need be used one, and construction fast, and the quality that continues is good; Its H shape aluminium jointing clamp, surfaces externally and internally at matrix duct and cover plate is provided with lock projection or/and the locking depression, perhaps be provided with the locking rod or/and the locking ditch, its effect is to reduce the drawing of duct surfaces externally and internally, compression, fracture in the time of can preventing to roll on the cover plate, wire clamp cover plate when crimping has been overcome be easy to produce the phenomenon that ruptures or come off.Make the sickleshaped cover plate can do can not rupture less than 90 the going up folding of degree.And lead enters the following foldings that cover plate behind the duct of H shape jointing clamp can be made 135 degree, makes lead can not skid off wire casing.The sickleshaped cover plate is crispaturaed along duct and lead bending, effectively fills up the space of duct, and lead is closely pressed together on wire clamp matrix and cover plate, driving fit in full force and effect after the crimping, and tightness greatly improves.And improve the level of pulling force, resistance, temperature rise greatly, accord with national border standard level fully, play the effect of continuing of high-quality lead.
