Abstract
The utility model provides a repair tube for a steel core aluminum alloy stranded wire, and the repair tube has the advantages of reliable crimping and convenient disassembly. The repair tube for the steel core aluminum alloy stranded wire is formed by opposing connection of two same half tubes in a drawing way. Each of the half tubes has a length of 420mm, an inner diameter of 43mm and an outer diameter of 68mm. In order to satisfy technical requirements of repair tubes of different types of the steel core aluminum alloy stranded wires, the physical dimension of the half tube can be adjusted to a length of 540mm, an inner diameter of 43mm and an outer diameter of 68mm. The repair tube has the advantages of simple structure, reliable crimping of conducting wires, flexible assembly and disassembly in a drawing way, convenient use, and good reinforcing effect.
Description
Technical field
The utility model relates to the splicing fitting that a kind of built on stilts electrical lead uses.
Background technology
The outer aluminium thigh wearing and tearing of twisted wire often can occur, fracture in work progress in overhead power line, circuit is in service also can be owing to the external force damage produces disconnected strand and the disconnected thigh of a vibration phenomenon.Find that this situation should in time give suitable conducting wire repair and process, the continuation of avoiding broken lot enlarges and causes the reduction of mechanical strength.The general drawer type repair sleeve that adopts carries out conducting wire repair now, and size was too little when existing repair sleeve assembled at drawer, easily distortion, and dismounting is inconvenient.Stipulate according to standard GB/T J 233 " construction of 110～500kV overhead power line and acceptance specification ": steel core aluminum alloy stranded wire accounts for 7%～25% of the aluminium thigh gross area at the damaged area of same section, should adopt repair sleeve to study for a second time courses one has flunked, when yet existing repair sleeve carries out crimping to steel core aluminum alloy stranded wire, because the length of repair sleeve is oversize, internal diameter is excessive, the problem that also can cause wire not press tightly.
Summary of the invention
The utility model provides a kind of repair sleeve for steel core aluminum alloy stranded wire, and crimping is reliable, convenient disassembly.
For achieving the above object, the utility model is taked following technical scheme:
The steel core aluminum alloy stranded wire repair sleeve is formed by two identical half body drawer type docking, and the length of half body is that 420mm, internal diameter are that 43mm, external diameter are 68mm.
The length of half body 420mm is not only applicable to the ground repair operation, and is convenient to be in operation and studies for a second time courses one has flunked, simultaneously so that two and half bodys folding with convenience when drawer assembles.The external diameter of half body 43mm internal diameter and 68mm, so that steel core aluminum alloy stranded wire is positioned between two and half bodys, after the assembling of two and half body drawer types it is carried out crimping, both having strengthened holding of wire puts forth effort, strengthened again the electrical contact performance of wire, so that the crimping of steel core aluminum alloy stranded wire is reliable, repair functional.
For the specification requirement of the repair sleeve that satisfies dissimilar steel core aluminum alloy stranded wires, can also adjust the physical dimension of half body, the length of half body is that 540mm, internal diameter are that 43mm, external diameter are 68mm.
The utility model is simple in structure, conductor compression jointing is reliable, the drawer mounting or dismounting are flexible, easy to use, reinforcing effect is good.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model.
Description of reference numerals: 1-half body; The 2-raised line; The 3-chute; 4-length; The 5-internal diameter; The 6-external diameter.
Embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
As shown in Figure 1, 2, steel core aluminum alloy stranded wire comprises two half identical bodys 1 with repair sleeve, joint face at half body 1 is provided with raised line 2 and chute 3, the raised line 2 of one of them half body 1 is complementary with the chute 3 of another half body 1, and this two and half body 1 is by raised line 2 and the docking of chute 3 drawer types.According to dissimilar steel core aluminum alloy stranded wires, adopt the repair sleeve of different structure size:
JX-900 repair sleeve, the length 4 of its half body are that 420mm, internal diameter 5 are that 43mm, external diameter 6 are 68mm, are applicable to JL/G3A-900/40 and JL/G1A-900/75 steel core aluminum alloy stranded wire;
JX-1035/75H repair sleeve, the length 4 of its half body are that 540mm, internal diameter 5 are that 43mm, external diameter 6 are 68mm, are applicable to the JLHA2X/G1A-1035/75 steel core aluminum alloy stranded wire.
When repairing wire, the steel core aluminum alloy stranded wire that needs are repaired is positioned between two and half bodys 1, and two and half bodys 1 carry out the drawer type assembling by raised line 2 and chute 3, again wire are carried out crimping.
