Description
Technical field
The utility model relates to a kind of heating cable, specifically a kind of overlength carbon fiber heating cable.
Background technology
Heating cable is heating in the winter time, accept by increasing people, the inner core of conventional heating cable is made up of cold line hot line, outside is made up of insulating barrier, ground connection, screen and oversheath, after heating cable energising, hot line generates heat, and runs between the temperature of 40 ~ 60 DEG C, be embedded in the heating cable in packed layer, heat energy is passed to heated body by the mode of heat transfer (convection current) with the far-infrared radiation mode of the 8-13um sent.
Although heating cable is mated formation flexibly, go for any area and house type.But owing to being adopt the heating of conventional metals silk, technical finesse is improper, easily produces electromagnetic radiation after energising, can produce harmful effect for old man, child, pregnant woman.So manufacturer is by arranging screen or changing metal ingredient and two method led mode and connect up, offset the electromagnetic radiation of heating cable.
Carbon fiber heating cable is that one is connected in parallel circuit, namely between these two power lines of live wire and ground wire, the mode of many carbon fiber heating cables in parallel carries out laying and work, the electric current of each root line with heating function is not more than 0.8A, so when carbon fiber heating cable ground heating system starts, electric current is steady, and electromagnetic radiation is little.
The mode of connection this in parallel of carbon fiber heating cable is because the resistance characteristic of carbon fiber self determines, and make the length of every root carbon fiber heating cable must control below 12.5 meters, if exceed this length, its heating property will obviously reduce at once.So the type of attachment of existing carbon fiber heating cable hangs many carbon fiber heating lines, every root carbon fiber heating line and power line vertical connection on a horizontal power line.And this mode of connection of heating cable can meet the laying needs of indoor ground-heating completely, so, carbon fiber heating cable is also mainly used for the limited application places of household ground heating heating system, Yoga room, sauna house, health care bed equal length at present, and application scenario is heated for the overlength of pipeline type, because self active length of carbon fiber heating cable limit, also cannot meet the use needs of this kind of overlength heating application scenario, therefore, existing carbon fiber heating cable also has very large use limitation.
Utility model content
The purpose of this utility model is just to provide a kind of overlength carbon fiber heating cable, to solve the problem that can not be used in pipeline class overlength heating occasion that existing carbon fiber heating cable exists.
The utility model is achieved in that a kind of overlength carbon fiber heating cable, be provided with in oversheath as two of the live wire of power line and zero line parallel wires, between two described wires, be provided with the carbon fiber heating line that some length is identical or substantially identical; First of root, row are connected into the end to end form of the tail of front after described carbon fiber heating line, the odd point of the above-mentioned end to end point of described carbon fiber heating line is connected on a wherein wire of two described wires, and the even number point of the above-mentioned end to end point of described carbon fiber heating line is connected on another root wire in two described wires.
Insulating barrier is enclosed with respectively on described wire He on described carbon fiber heating line.
The utility model is connected to the connection type on different conductor in turn with the head and the tail tie point of carbon fiber heating line, ensure that the parallel-connection structure of all carbon fiber heating lines, make every root carbon fiber heating line still can keep maximum heating efficiency, and the syndeton end to end successively of carbon fiber heating line just makes the length of heating cable to extend arbitrarily, thus form the overlength heating cable with the single flat belt that but length exactly alike with common carbon fibers heating cable heating efficiency can extend arbitrarily, thus overcome the use limitation of existing carbon fiber heating cable existence, achieve the application of carbon fiber heating cable in the overlength occasions such as pipeline.
The utility model, owing to overcoming the technological deficiency of common carbon fibers heating cable length limited, thus, can be useful in the various working environments such as deicing or snow melting is antifreeze, pipe insulation, soil heating.The antifreeze deicing or snow melting comprising the various places such as exterior stair, overpass, building roof, gutter, drainage pipe, parking lot, track, airfield runway, highway, ramp, bridge floor of deicing or snow melting, also comprise the anti-freeze anti-damages of anti-sleet disaster such as electric power tower, cable, equipment, accumulated snow, the icing hidden danger brought can be prevented, improve fail safe, ensure the normal work of electric power facility; Pipe insulation comprises the pipe insulation of petroleum pipeline, water supply line, fire protection pipeline etc., also comprises the antifreeze of the outdoor and equipment such as tank body insulation, oil, electric power and insulation, can ensure the normal work and use of pipeline, tank body and equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the wiring schematic diagram of the carbon fiber heating line in the utility model.
Embodiment
As shown in Figure 1, the utility model is provided with in oversheath 1 as two of the live wire of power line and zero line parallel wires 2, is provided with the carbon fiber heating line 3 that some length is identical or substantially identical between two wires 2; Insulating barrier is enclosed with respectively on two wires 2 He on carbon fiber heating line 3.Insulating barrier adopts heating cable common used material to make, the injection molding body that oversheath 1 is commonly used for heating cable.
In Fig. 2, first of root, row are connected into the end to end form of the tail of front after carbon fiber heating line 3, and be positioned at the centre of two wires 2, the above-mentioned end to end point of carbon fiber heating line 3 is connected on a wire (live wire) two wires from the odd point of cable section start, the even number point of the above-mentioned end to end point of carbon fiber heating line 3 is connected on another root wire (zero line) in two wires.Carbon fiber heating line can infinitely continue down in this way, forms a flat overlength carbon fiber heating cable (Fig. 1).
Due to the parallel connection structure of carbon fiber heating line, the operating current of each root carbon fiber heating line is made to be not more than 0.8A, so the starting current of carbon fiber heating cable is steady, and due to the electromagnetic radiation of carbon fiber heating line little, thus the present invention can also omit the setting of the screen in conventional heating cable, and the cost of manufacture of heating cable is reduced further.
The pipe laying mounting means of carbon fiber heating cable comprises following three kinds:
One, straight line is wound around:
By one or more carbon fiber heating cable along pipeline straight line setting on one side, fixed by carbon fiber heating cable with aluminum foil and adhesive tape or installation aluminium strip, at second end of pipeline, constant spacing is not more than 50cm.
Two, wave is wound around:
Heating cable is combined with each other with wave and pipeline, cable length needed for every mitron road is determined by load needed for design every meter, and then determine wave radius of curvature R, should wave amplitude be made even during laying as far as possible, to ensure the Homogeneouslly-radiating of carbon fiber heating cable system, paste carbon fiber heating cable with aluminum foil and adhesive tape along Wave curved, or paste knee with aluminum foil and adhesive tape.
Three, spiral winding:
Carbon fiber heating cable is spirally wrapped on pipeline equably by every mitron road Len req, fixes along the hand of spiral with aluminum foil and adhesive tape, or fix the upper end of heating cable and pipeline with aluminum foil and adhesive tape.
