The creep-resistant aluminum alloy copper-aluminum transition terminal has the advantages that: 1) the conductor connecting pipe is made of creep-resistant aluminum alloy so that the conductor connecting pipe is consistent with a cable conductor from material components to creeping property; 2) the inner hole of the aluminum connecting pipe adopts the structures of a fan, a tile, a semi-circle or the like and is consistent with domestic low-voltage power cable conductors so that the construction is convenient and the heat stability of connectors can be greatly improved; and 3) the terminal is manufactured by adopting the friction welding technology.
Description
Technical field
Interference of the utility model and an anti-creep transition copper and aluminum alloy terminal, specifically applied to a low-voltage power distribution network cable connectors and industrial transition joints with copper and aluminum.
Background technology
Along with the high speed development of China's economic construction, every profession and trade continues to increase the demand of electric power, and the market space of wires and cables industry is huge.But the copper, the aluminium conductor itself that in the electric wire product structure, account for main component exist the shortcoming that is difficult to overcome, and division is following:
1, the big (8.89g/cm of the density of pure cu conductor
3), and the copper ore resource whole world is deficient, China is again a typical poor copper state.Leap to the first in the world from the smart copper consumption figure of China in 2004, cause the electric equipment cost to increase considerably.
2, the mechanical strength of fine aluminium conductor is on the low side, and welding performance is poor, and contact resistance is big, in engineering project, applies being restricted; Poorer because of the creep-resistant property of fine aluminium conductor, cause the aluminium conductor power cable on practical applications, frequently to break down.
3, the mechanical performance and the electric property comprehensive advantage that have along with aluminium alloy technological continuous development and perfect technology, particularly creep resistant aluminium alloy conductor make its advantage that is used for electric wire and cable conductor more and more obvious, and its market share is ascendant trend year by year.
Usually the copper-aluminium transition terminal that manufactures and designs mainly is made up of copper lug and conventional aluminium tube connector.Its structure is shown in Figure 1:
Its nose adopts electrician's copper, tube connector to adopt the common aluminium of 1350 trades mark more more.It is following that ordinary copper aluminium transition terminal is used for its major defect of aluminium alloy cable:
1, the general aluminium of 1350 trades mark easy place creep under the effect that temperature constantly changes for a long time makes its physical dimension produce irreversible change.
2, cylindrical tube connector is used for lv power cable special-shaped conductor (like fan-shaped, watt type, semi-circular); Because the two shape differs too big; Even when joint, take the shaping measure; Also be difficult to guarantee to accomplish conductor the profile of rounding, cause between conductor outer surface and the tube connector inwall space inhomogeneous, bring hidden danger for cable operation steady in a long-term.
Summary of the invention
The purpose of the utility model is that a kind of construction that increases substantially the stability of cable joint, reduces joint significantly of development becomes, and is applied to the creep resistant aluminum alloy copper aluminium transition terminal of low voltage electric network and industrial power distribution net.
The utility model creep resistant aluminum alloy copper aluminium transition terminal comprises: copper lug 1, and the aluminium connecting tubes 2 that links to each other with copper lug 1, aluminium connecting tubes 2 is provided with interconnecting hole 3.
Described interconnecting hole cross sectional shape is fan-shaped, watt shape, semicircle and and the corresponding shape of the cross-section of cable.
The material of described tube connector 2 is the creep resistant aluminium alloy, and its chemical constituent mass percent is:
Si≤0.12，Fe?0.35-0.75，Cu?0.15-0.25，Mg≤0.05，Zn≤0.05，
B 0.001-0.04, other element (single)≤0.03, other element (summation)≤0.1, Al surplus.
The material of said copper lug 1 is a T2 trade mark electrician copper.
Adopt the aluminium connecting tubes of creep resistant aluminum alloy materials as the copper-aluminium transition terminal, its performance meets company standard Q/WL.J01-XX requirement, and specific targets are following.
1) mechanical performance
Tensile strength (MPa): annealed condition 60-115
Half annealing or unannealed state 105-150,
Elongation >=10%
2) electric conductivity
20 ℃ of resistivity (Ω mm
2/ m): mean value≤0.028264, individual point≤0.028450
%IACS: mean value >=61.0, individual point >=60.6
The preparation method of the utility model creep resistant aluminum alloy copper aluminium transition terminal, its step is following:
1) adopt T2 trade mark electrician copper rod to form copper lug 1 through machining according to the specification pattern of design;
2) adopt the creep resistant aluminium alloy to be cast into aluminium connecting tubes, the chemical constituent mass percent of creep resistant aluminium alloy is:
Si≤0.12，Fe?0.35-0.75，Cu?0.15-0.25，Mg≤0.05，Zn≤0.05，
B 0.001-0.04, other element (single)≤0.03, other element (summation)≤0.1, Al surplus.
3) adopt friction-welding technique that copper lug 1 and aluminium connecting tubes 2 are welded together;
4) the copper-aluminium transition terminal is repaired back vanning warehouse-in.
The advantage of the special-shaped aluminum alloy copper aluminium of the utility model creep resistant transition terminal is:
1, adopting the creep resistant aluminium alloy to do conductor connecting tube reaches an agreement itself and cable conductor from the material composition to the croop property;
2, the aluminium connecting tubes endoporus adopts structures such as fan-shaped, watt shape, semicircle consistent with domestic lv power cable conductor, and convenient construction increases substantially the joint thermal stability;
3, adopt Friction welding technique, guarantee that transition terminal cast interface under the effect that temperature constantly changes does not change.
