Description
Technical field
In the present invention relates to, the open-air transmission line of low pressure field, specifically a kind of transmission pressure with heating.
Background technology
More than existing overhead transmission line 10KV reaches, mainly be to be made of transmit electricity electric wire and tower bar, insulator etc., its electric wire is a steel reinforced aluminium conductor, and it is made around sub-thread or multiply steel wire external layer by the multiply aluminum steel.The main current-carrying electric energy transmitting of aluminum steel, steel wire bears mechanical stress, and the tower bar is used for support wire, and insulator is used for holding up or hangs lead and make lead and the insulation of tower bar.In the open air in the transmission line, climate change can make a big impact to circuit, when running into the bad weather of long-time low temperature sleet, conductive line surfaces is easy to be covered by ice and snow and freeze, as can not in time disposing the ice and snow on lead top layer, can make its ice sheet long-pending more thick more, when having surpassed the load capacity of lead and tower bar, be prone to wire fracture or the tower bar is pressed down, even collapse, destroy transmission system, caused very big economic loss.When in January, 2008, China south met with very serious low-temperature freezing rain and snow disaster, transmission line was subjected to heavy damage, and freezing on the cable is difficult to remove, and had also caused personnel casualty accidents in the process of repairing and maintenance.
Summary of the invention
The objective of the invention is provides a kind of simple and reasonable, in light weight, with low cost in order to solve the deficiency of above-mentioned technology, and when transmission line during at low temperature sleet icing, the heating wire that can connect in the core produces the transmission pressure of the band heating of heat melts icing layer.
The present invention solves the scheme that its technical problem takes: a kind of transmission pressure with heating; comprise conductor circle aluminum steel; electric heating wire; electric heating wire is that the lead outside that high-quality siderochrome aluminium electrothermal alloy material is made has fluoroplastic insulation layer composition; fibre reinforced plastic reinforcement; it is characterized in that being provided with the column type fibre reinforced plastic reinforcement in the middle of the lead; two electric heating wire side-by-side helixs are wrapped on the reinforcement; the terminal short circuit constitutes the loop; be provided with protective layer in the electric heating wire outside, outside conductor circle aluminum steel is twisted into transmission pressure around protective layer.
Described two electric heating wire diameters are that the pitch that 1.0mm is 600mm-800mm side by side is spirally wound on the reinforcement, and the terminal short circuit makes it constitute the loop.
The protective layer of described electric heating wire outside is a nonwoven fabrics, and overlapping wrapped nonwoven fabrics is thick to be 0.15mm, and wide is the protective layer of 40mm.
The present invention is reasonable in design, and is in light weight, easy to manufacture, and cost is low, in extensively being suitable for making somebody a mere figurehead, in the open-air transmission line of low pressure, can solve effectively that lead is not covered by ice and snow in the low temperature sleety weather.
The present invention is further described below in conjunction with drawings and Examples.

Mark among Fig. 1,2: 1, electric heating wire, 2, wire stylet, 3, conductor circle aluminum steel, 4, protective layer.
Embodiment
By Fig. 1; 2 as can be known; a kind of transmission pressure with heating; comprise conductor circle aluminum steel 3; electric heating wire 1; electric heating wire is that the lead outside that high-quality siderochrome aluminium electrothermal alloy material is made has fluoroplastic insulation layer composition; fibre reinforced plastic reinforcement; in the middle of lead, be provided with the wire stylet 2 of column type fibre reinforced plastic reinforcement; two electric heating wire 1 side-by-side helixs are wrapped on the wire stylet; the terminal short circuit constitutes the loop; be provided with protective layer 4 in the electric heating wire outside; outside conductor circle aluminum steel 3 is twisted into transmission pressure around protective layer 4, and the line of fibre reinforced plastic reinforcement 2 is directly wanted uniformity in the production process, guarantees the tensile strength of lead; two electric heating wire diameters are that the pitch that 1.0mm is 600mm-800mm side by side is spirally wound on the reinforcement, and the terminal short circuit makes it constitute the loop.The laying tension of electric heating wire is set 6-8N and is advisable, and the protective layer of electric heating wire outside is a nonwoven fabrics, and overlapping wrapped nonwoven fabrics is thick to be 0.15mm, and wide is the protective layer of 40mm.Its production process is wrapped in through wire drawing, softening conductor circle aluminum steel, electric heating wire on the wire stylet 2 of fibre reinforced plastic reinforcement, with the wrapped electric heating wire of nonwoven fabrics form protective layer, the round aluminum steel of conductor is stranded in protective layer and constitutes transmission pressure finished product, check outward, packs.
The present invention is simple in structure, reasonable in design, the weight saving of unit length, and easy to manufacture, cost is low, and construction install convenience is in extensively being suitable for making somebody a mere figurehead, in the open-air transmission line of low pressure.When running into the weather of low temperature sleet, use power supply 220V to get final product, electric heating wire is inserted the 220V power supply at any time heat, can solve the problem that open-air transmission line wire surface freezes effectively.
