Description
Technical field
The present invention 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, except the heating cable of foreign brand name, domestic heating cable commercially also occupies a tiny space with the price of its material benefit and stable performance.Heating cable has safety, efficient, easy control, easily installs the various features such as (arbitrary shape can be become to install), life-span length, small investment, and the scope of application is more and more extensive.
The inner core of 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 run 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.
Heating cable take electric power as the energy, using heating cable as heater, heat is produced after heating cable energising, its heating temp is generally at 40 DEG C-60 DEG C, by contact conduction, heat packs is trapped among the medium of its periphery, then adds hot-air by convection type, and heat conduction accounts for 50% of heating cable caloric value.In addition, the human body far infrared of 7-10 microns the most suitable can also be produced after heating cable energising, to human body and space radiation.This part heat accounts for 50% of caloric value, and heating cable heating efficiency is close to 100%.
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 fibre material is a kind of Novel environment-friendlymaterial material of current field of heating, because advantages such as the life-span is long, electromagnetic radiation is little, environmental protection and energy saving, heat efficiency height, progressively having entered field of heating, is also the new material starting floor heating and field of heating in 2009.Carbon fiber heating cable adopts nonmetallic materials carbon to be heater, and thus can ensure not to be oxidized under heater low temperature, the life-span can ensure more than 50 years.
Carbon fiber also has new contribution at present on alternative heating materials core heater, abroad, on the core heater of a lot of energy-saving heating equipment by before the metal material that generally adopts progressively be upgraded to carbon fibre material, corrosion-resistant, anti-oxidant (metal is easily oxidized and causes partial breakdown), the high stability, the feature such as life-span longer (a lot of product generally can reach the steady operation time of 100000 hours at 300 degrees Celsius) and thermal conversion rate high (more than 97%) that make use of material are mainly considered in the application of carbon fibre material in heating.
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.
Summary of the invention
Object of the present invention 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 present invention 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 present invention 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 present invention, 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.
