Description
Technical field
The utility model relates to a kind of electric power system carriage hollow wire, the middle intensity aerial condutor of the big capacity power transmission and distribution of particularly a kind of basic routing line and distribution line.
Background technology
At present, the lead that transmission line adopts has steel reinforced aluminium conductor, aluminium Baogang core aluminum stranded wire etc., and these transmission pressures all adopt the conventional aluminium material.Because the tensile strength of conventional aluminium material is low, the strengthening core elements such as additional steel core or aluminium Baogang core of in the conductor structure design, having to.Strengthening core elements such as steel core or aluminium Baogang core not only increase wire weight, significantly increase cost of transportation, and need higher iron tower and more firm iron tower foundation, and floor space is big.In addition, in the transmission line of alternation current, the magnetic hysteresis loss that reinforcing elements such as steel core or aluminium Baogang core also can cause has reduced the circuit transmission capacity.
The utility model content
The purpose of this utility model is to overcome defective and the deficiency of existing overhead power transmission with lead, provides that a kind of high strength, transmission capacity are big, the middle intensity aerial condutor of long service life.
The technical scheme that realizes the utility model purpose is a kind of middle intensity aerial condutor, comprises the non-heat-treatable aluminum alloy single line that multilayer concentric is stranded.
The single line shape that described each layer non-heat-treatable aluminum alloy single line is adopted can be identical or inequality, all can be for circular or special-shaped.
Can be gapped between described each layer non-heat-treatable aluminum alloy single line.
The scope in described gap is 0.2～2mm.
Described each layer non-heat-treatable aluminum alloy single line can select every layer all closely stranded/every layer all dredge around stranded/one or more layers dredges closely stranded around stranded+remainder layer arbitrarily.
Adopted technique scheme, the utlity model has following beneficial effect: (1) whole aerial condutor of the present utility model adopts aluminium alloy wire simultaneously as conducting element and reinforcing element, first, production technology is easy, cost is low, efficient is high; The second all aluminium alloy twisted wire is compared with isodiametric steel reinforced aluminium conductor, and the sag characteristic is good, and the comparable steel reinforced aluminium conductor of average tower height reduces about 3 meters, can effectively reduce the line construction investment; The 3rd, percentage elongation is big, and the aluminium alloy single line is 2 times of aluminum steel, makes this aerial condutor have good overload capacity and fatigue properties; The 4th, hot properties is good, and this aerial condutor does not produce loss of strength at 80 ℃ of continuous services, moves under higher temperature, and loss of strength is also few, and hot operation is played the artificial aging effect, raising conductivity 2～5%; The 5th, the load aspect is compared with the steel reinforced aluminium conductor of same diameter, horizontal loading, vertically quite powerful, and vertical load can reduce 10%; The 6th, compare with the steel reinforced aluminium conductor of same diameter, when externally condition was identical, when promptly division number, heading spacing, distance to the ground, phase spacing etc. were identical, its ground electric field intensity, magnetic field intensity, radio interference, audible noise etc. were also identical; The 7th, easy construction, this aerial condutor is twisted into by same material, and the feasible gold utensil that continues is simple, only need 1 its yield strength of splicing sleeve to be about 1.5 times of aluminum steel, compression-type continued be difficult for to produce lead bulge or lantern phenomenon, can reduce the crimping workload to anti-strong wire jumper, raises the efficiency, simultaneously because the hardness (Brinell hardness is 85) of aluminium alloy wire is 2 times of aluminum steel, but the weight ratio steel reinforced aluminium conductor is light, can reduce the conductive line surfaces scratch during the construction line-putting, improves construction quality.The 8th, this aerial condutor steel core free, there are not eddy current and magnetic hysteresis loss, alternating current-direct current resistance is smaller, ampacity than the steel reinforced aluminium conductor of same diameter is big, particularly during large capacity transmission, consumption reduction obviously, can satisfy the engineering instructions for use, reach the purpose of energy-conservation, consumption reduction, environmental protection, have obvious economic benefit and social benefit, be of great importance to building " resource-conserving, environmentally friendly " electrical network, this aerial condutor has natural resistivity to atmospheric corrosion simultaneously, has avoided the couple corrosion between aluminum steel and the galvanized steel wire, but extension lead service life.
(2) the structure choice scope of middle intensity aerial condutor of the present utility model is big, can select only structure for use according to actual conditions.
(3) the utility model is that a kind of transmission capacity is big, high, low, the long service life of project cost of pulling force substance ratio, and loss is little, the novel conductive wire of energy-conserving and environment-protective.
