Abstract
The utility model relates to a power transmission wire with the heating function, which belongs to the field of middle-low-voltage field power transmission lines. The power transmission wire comprises a conductor round aluminum wire, an electrical heating wire and a fiber-reinforced plastic reinforcing element, wherein the cylindrical fiber-reinforced plastic reinforcing element is arranged in the middle of the power transmission wire, the electrical heating wire is formed by fine fe-cr-al electrothermal alloy wire whose outer portion is provided with an insulating layer, two electrical heating wires are spirally wound on the fiber-reinforced plastic reinforcing element in parallel, and a terminal is short connected to form a return circuit, a nonwoven covering layer is arranged on the outer portion of the electrical heating wire, and the conductor round aluminum wire outside is twisted to be a power transmission wire around the nonwoven covering layer. The utility model has the advantages of simple structure, reasonable design, simple manufacture, low production cost and convenient construction and installation, and weight in unit length is lightened, the electrical heating wire can be connected with a 220V power supply to heat anytime in low-temperature rain and snow weather, and the problem that the surface of an electrical cable is freezing can be effectively solved.
Description
Technical field
During the utility model 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 caused personnel casualty accidents in the process of repairing and maintenance.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, provide a kind of simple and reasonable, in light weight, with low cost, when open-air transmission line during at low temperature sleet icing, the heating wire that can connect in the wire stylet produces the transmission pressure of the band heating of heat melts icing layer.
The utility model solves the scheme that its technical problem takes: a kind of transmission pressure with heating; comprise conductor circle aluminum steel; electric heating wire; 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; electric heating wire is provided with insulating barrier by high-quality siderochrome aluminium electrothermal alloy lead outside and forms; two electric heating wire side-by-side helixs are wrapped on the fibre reinforced plastic reinforcement; the terminal short circuit constitutes the loop; be provided with the nonwoven fabrics protective layer in the outside of electric heating wire, outside conductor circle aluminum steel is twisted into transmission pressure around the nonwoven fabrics protective layer.
The utility model 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.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the winding schematic diagram of electric heating wire at fibre reinforced plastic reinforcement.
Mark among Fig. 1,2: 1, electric heating wire, 2, reinforcement, 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; fibre reinforced plastic reinforcement 2; in the middle of lead, be provided with column type fibre reinforced plastic reinforcement 2; the lead outside that electric heating wire 1 is made by high-quality siderochrome aluminium electrothermal alloy material is provided with that the fluoroplastic insulation layer forms; two electric heating wire 1 side-by-side helixs are wrapped on the fibre reinforced plastic reinforcement 2; the terminal short circuit constitutes the loop; be provided with nonwoven fabrics protective layer 4 in the outside of electric heating wire 1, outside conductor circle aluminum steel 3 is twisted into transmission pressure around the nonwoven fabrics protective layer.The utility model is simple in structure, reasonable in design, and is easy to manufacture, and cost is low, the weight saving of unit length, 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, heating wire uses power supply 220V to get final product, and can insert the power supply heating during use at any time, can solve the problem that cable surface freezes effectively.
