Abstract
The utility model provides a when the splicing sleeve carries out the crimping to aluminum alloy core high conductibity aluminum stranded conductor, cause the aluminum stranded conductor and harm or cracked problem that aluminum alloy core high conductibity aluminum stranded conductor splicing sleeve solves to have now. The utility model provides an aluminum alloy core high conductibity aluminum stranded conductor splicing sleeve, this splicing sleeve include external pressure takeover, aluminium bushing pipe and aluminum alloy bushing pipe, the utility model has the advantages of that shock -resistant fatigue resistance is strong, the grip distributes is even, bear the weight of and holding the reinforce, effectively avoiding using for a long time the grip lax, the suitable popularization and application. Meanwhile, thus this splicing sleeve has reached energy saving and consumption reduction's target owing to used three pieces bushing pipes to reduce the weight that outer diameter that the external pressure took over has reduced the splicing sleeve. Have using value and vast potential for future development.
Description
Technical field
The utility model relates to the connection gold utensil that wire connects in a kind of electric power system overhead power line, and particularly a kind of aluminium alloy core high conductivity aluminium stranded conductor splicing sleeve, belongs to power engineering apparatus field.
Background technology
In electric power system overhead power line, often there is as inadequate in length, that the disconnected stock of wire wearing and tearing is serious problem in the connection that can relate between wire and wire, just uses splicing sleeve to connect in the case.For encouraging technological progress, the hard-drawn aluminium wire (conductance is respectively 61.5%IACS, 62%IACS, 62.5%IACS, 63%IACS) of different high conductivity is combined with LHA1 and LHA2 respectively, replace common hard-drawn aluminium wire, thus reduction resistance loss, reach energy-saving and cost-reducing target at long distance, high-capacity direct current transmission line.The splicing sleeve of current connection steel-core-aluminium hinge line the core of two wires to be connected is put steel pipe crimping, and then put aluminum pipe and carry out crimping respectively in the both sides of crimping point and form.It is little that the aluminium alloy core of aluminium alloy core high conductivity aluminium stranded conductor has D.C. resistance, conductance is high, the advantages such as quality is little, but due to aluminium alloy core case hardness low relative to Q235, traditional splicing sleeve structure cannot adapt to the connection of aluminium alloy core high conductivity aluminium stranded conductor at all.Therefore, a kind of lead splicing sleeve that can adapt to aluminium alloy core high conductivity aluminium stranded conductor and connect is needed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of aluminium alloy core high conductivity aluminium stranded conductor splicing sleeve, mainly solves existing splicing sleeve when crimping aluminium alloy core high conductivity aluminium stranded conductor, aluminium stranded conductor is caused to the problem of damage or fracture.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of aluminium alloy core high conductivity aluminium stranded conductor splicing sleeve, this splicing sleeve comprises outer aluminium hydraulic pressed connecting pipe, aluminium bushing pipe and aluminium alloy bushing pipe; The inside center position of described outer aluminium hydraulic pressed connecting pipe is aluminium alloy bushing pipe, and in the both sides of described aluminium alloy bushing pipe, symmetrically an aluminium bushing pipe respectively arranged by type.
Further, described aluminium alloy bushing pipe and aluminium bushing pipe are hollow cylinder shape.
Further, described aluminium alloy bushing pipe material is 6063 aluminium alloys, and aluminium bushing pipe material is 1050A aluminium.
The beneficial effects of the utility model:
Splicing sleeve of the present utility model is center configuration aluminium alloy bushing pipe in aluminium hydraulic pressed connecting pipe outside, and the both sides outside in aluminium hydraulic pressed connecting pipe respectively configure an aluminium bushing pipe.Internal lining pipe can firmly be crimped formation good conductor with splicing sleeve main body, aluminium alloy core and aluminium stranded conductor by it, and to aluminium alloy core high conductivity aluminium stranded conductor without any damage.This utility model has that shock-resistant fatigue resistance is strong, grip is evenly distributed, carry the power of hold by force, effectively avoids using the advantages such as grip is loose for a long time, suitablely applies.Meanwhile, this splicing sleeve reduces the outside dimension of outer aluminium hydraulic pressed connecting pipe owing to employing three bushing pipes thus decreases the weight of splicing sleeve, reaches energy-saving and cost-reducing target.Have using value and vast potential for future development.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of aluminium alloy core high conductivity aluminium stranded conductor splicing sleeve, this splicing sleeve comprises outer aluminium hydraulic pressed connecting pipe 1, aluminium bushing pipe 2 and aluminium alloy bushing pipe 3; The inside center position of described outer aluminium hydraulic pressed connecting pipe 1 is aluminium alloy bushing pipe 3, and in the both sides of described aluminium alloy bushing pipe 3, symmetrically an aluminium bushing pipe 2 respectively arranged by type.
Described aluminium alloy bushing pipe 3 is hollow cylinder shape with aluminium bushing pipe 2.
Described aluminium alloy bushing pipe 3 material is 6063 aluminium alloys, and aluminium bushing pipe 2 material is 1050A aluminium.
During installation, expose aluminium alloy core by after the outer aluminium stranded conductor of two aluminium alloy core high conductivity aluminium stranded conductor ends of continuing blocks, then aluminium alloy core high conductivity aluminium stranded conductor is inserted into respectively the center of aluminium alloy bushing pipe 3 from the end being provided with aluminium bushing pipe 2.Aluminium alloy bushing pipe 3 is crimped from center to two ends, thus aluminium alloy bushing pipe 3 and two aluminium alloy cores connect as one, afterwards the aluminium alloy bushing pipe 3 after crimping is pushed in outer aluminium hydraulic pressed connecting pipe 1, two aluminium bushing pipes 2 are pushed respectively in outer aluminium hydraulic pressed connecting pipe 1, with hydraulic method by outer aluminium hydraulic pressed connecting pipe 1, aluminium bushing pipe 2 and aluminium alloy core high conductivity aluminium stranded conductor compress thus ensure splicing sleeve have enough grips to wire.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
