Abstract
The utility model discloses a steel-cored formed large-section aluminium-alloy conductor which comprises a steel-cored high-strength aluminum-alloy stranded conductor (2), and an outer conductor layer (1) consisting of multiple layers of Z-shaped conductors is wound around the steel-cored high-strength aluminum-alloy stranded conductor (2). The steel-cored formed large-section aluminium-alloy conductor has the advantages that: (1) the cross-section utilization rate of the conductor is larger; (2) the smooth surface of the formed conductor can reduce the influence of wind loads, and the wind load of the conductor is lower than that of a circular concentric stranded overhead conductor with the same diameter; (3) the formed conductor has good self-damping properties, therefore, the conductor has a good aeolian-vibration-resistant capacity and a good capacity of resisting vibrations caused by storm wind, rain, snow and dust storms; (4) because the outside surface of the conductor is smooth, therefore, the ice coating time of the conductor is reduced, and the ice and snow thawing is accelerated when temperature changes; (5) the product structure has a greater drag-to-weight ratio, which is an ideal characteristic of a long-span conductor; and (6) the conductor is more convenient to be matched with fittings, and the fittings can adopt supporting fittings same as those of the circular concentric stranded overhead conductor.
Description
Technical field
The utility model relates to the lead technology field, specifically a kind of heavy in section moulding aluminium alloy conductor.
Background technology
The construction of China's electric power system exists power supply (power plant), light electrical network phenomenon emphatically for a long time.In the lasting China that sharply increases of electricity needs, the construction of electrical network has become important topic, and is overheated for effectively solving the power supply construction investment that exists in the current power construction, and the electric power asset configuration disproportionate development drawback that the power grid construction under-capitalization causes.State Grid Corporation of China begins to strengthen on a large scale the power grid construction dynamics of investment, accelerates the extra-high voltage grid construction, improves transregional ability to transmit electricity.The electrical network focus technology research field that in strengthening the power grid construction process, relates to has the transmitting capacity of the electric wire netting of raising technology---and carry out the research that is the basis with novel conductive wire and novel shaft tower, comprise the research of the transmission pressure of high strength, high temperature resistant, low arc drop, low-resistivity.Exploitation to steel core moulding heavy in section aluminium alloy conductor is arisen at the historic moment, and according to electric power development and China's power transmission and transformation specification requirement, south electric network will have more than 3,000 ton of this product bid in next year; The output value will reach more than 6,000 ten thousand; Profit is nearly 6,000,000, and along with the promotion and application of this product, benefit will be more outstanding.In the recent period in the project; Propose by southwestern Electric Power Design Institute and Guizhou Electric Power Design Institute; The small stream Lip river is crossed Right Bank Hydropower Station and is sent electric Guangdong ± 500kV common-tower double-return DC line engineering 30mm heavy icing area to intend recommendation employing JLHA2X/G1A-1035/75 steel core moulding aluminium alloy wire, and structure and technology are designed and developed by enterprise voluntarily.
Heavy in section (moulding) aluminium alloy stranded conductor has all proposed more strict requirement to lead production equipment and production technology; And the domestic precedent of also not making heavy in section (moulding) aluminium alloy stranded conductor; Thereby the research of steel core moulding heavy in section aluminium alloy conductor will fill the domestic gaps more apparent necessity.
Summary of the invention
The purpose of the utility model is that development is a kind of when having transmission capacity, and diameter of wire is less, but sizable pulling force weight ratio is arranged, good antivibration ability, i.e. self-damping function admirable; Corrosion-resistant and can reduce or stop the lead generation to wave performance is to be applicable to that heavy icing area, wind load are big, the aerial condutor in the abominable area of climatic environment.
The utility model steel core moulding heavy in section aluminium alloy conductor comprises:: steel core high-strength aluminum alloy twisted wire conductor 2, the steel core high-strength aluminum alloy twisted wire conductor 2 outer wire external layers 1 that are wound with multilayer Z type lead composition.
The aluminium alloy of described steel core high-strength aluminum alloy twisted wire conductor 2 is aluminium-magnesium-silicon system.
Described Z type lead outer arc central angle is α, and the central angle of middle arc is β, and the radius of outer arc, middle orphan, inner arc is φ

The conductor layer that described Z type lead is formed is that the mutual interlock of many Z type leads is assembled.
The conductor layer that described S type (the S type is the opposite direction of Z type) lead is formed is that the mutual interlock of many S type leads is assembled.
The described lead made from SZ type aluminium-magnesium-silicon alloy single line and galvanized strand wires concentric stranding.That is: steel core high strength (aluminium-magnesium-silicon system) aluminium alloy stranded conductor, specification is 1040/75, the model specification of standard is JLHA2X/G1A---1040/75.
At JLHA2X/G1A---in the selection of 1040/75 structure; Adopt galvanized strand wires: 1+6+12/2.24; Adopt high strength (aluminium-magnesium-silicon system) aluminium alloy stranded conductor: 10/4.42+14/4.47+18/4.58+22/4.62; Internal layer wherein: S type 10/4.42 (being equivalent to circular diameter), adjacent internal layer: Z type 14/4.47 (being equivalent to circular diameter), adjacent outer: S type 18/4.58 (being equivalent to circular diameter), skin: Z type 22/4.62 (being equivalent to circular diameter), the external diameter of lead: 40.10 ± 1%d mm, total cross section: 1114 mm
2(being shown in the following figure)
The advantage of the utility model steel core moulding heavy in section aluminium alloy conductor is:
1. bigger conductor cross-section utilance.The round line concentric gallows empty conductor of it and same structure is during with diameter, and the cross section increases by 20 ~ 25%., its structure is tight, and mutual embedding joins very firmly and smooth surface between each single line, uses in the highlands and can reduce corona loss;
2. smooth shaped conductors surface can reduce the influence that wind carries, and its wind carries lower than the round line concentric gallows empty conductor of same diameter;
3. therefore the good self-damping characteristic of shaped conductors has good anti-aeolian vibration and uprising wind, rain, snow and sandstorm to cause the ability of vibration;
4. because its lead smooth outer surface, thereby reduced time of wire icing, temperature is stretched the thawing of ice and snow when becoming and is quickened;
5. this product structure has bigger pulling force weight ratio, is the desired characteristics of crossing over lead greatly;
6. gold utensil is supporting comparatively convenient, can adopt the identical supporting gold utensil of round line concentric gallows empty conductor;
This conductor structure design use the performance and the cross section of material.And the connection of gold utensil is similar with general lead, does not have specific (special) requirements.The conductor structure of close and firm can carry out the lead construction smoothly; It has overturned original round line some ideas of strand with one heart, with its distinctive shape, has promoted the level of used for transmission line lead; Make the lead life cycle longer, more reasonable, guaranteed the safe operation of lead.
