In the utility model, the accompanying-heat cable of tool kelvin effect is outer surfaces single or the many oil field petroleum pipelines that are laid in equably, it includes heart yearn, is coated on the insulating barrier of described heart yearn outer surface, be coated with one deck in the periphery of described insulating barrier and will pass into electric current and concentrate on the magnetic steel tube boot of endosexine, between described steel tube dirt-proof boot and described insulating barrier, be filled with packing layer, described accompanying-heat cable welding or be banded on the outer wall of described oil field petroleum pipeline, and be welded to connect galvanic circle joint between the steel tube dirt-proof boot of described accompanying-heat cable tail end and heart yearn.
The material of described heart yearn is oxygen-free copper-wire, and described heart yearn screws and forms in the shape of a spiral again after twisting into thigh by sub-thread copper rod or stranded copper wire line hinge.
Described stranded copper wire twisted wire hinge twists into after helical form, and the pitch screwing is 10-50 centimetre.
Described steel tube dirt-proof boot is the steel pipe with ferromagnetic property, and wall thickness is 1.5-3 centimetre.
The material of described packing layer is glass wool cloth, fills up the gap between described insulating barrier and described steel tube dirt-proof boot.
The thickness of described insulating barrier is between 1.1～2.0mm, and material is polytetrafluoroethylene.
The rated voltage of described accompanying-heat cable is 3000V or below 3000V, temperature resistant grade is below 250 DEG C or 250 DEG C.
Brief description of the drawings
Fig. 1 is the structural representation of accompanying-heat cable in the utility model.
Fig. 2 is the operation principle schematic diagram of accompanying-heat cable in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is elaborated.
As shown in Figure 1, tool kelvin effect companion heat (heating) cable in the utility model, its rated voltage is 3000V and below 3000V, temperature resistant grade is below 250 DEG C and 250 DEG C, include core 1 and be coated on the insulating barrier 2 in heart yearn 1 outside, be coated with a ferromagnetic steel tube boot 4 in the periphery of insulating barrier 2, between steel tube dirt-proof boot 4 and insulating barrier 2, be filled with packing layer 3, this packing layer 3 is mineral matter layer, mineral material is wherein glass wool cloth, be used for filling the gap between insulating barrier 2 and steel tube dirt-proof boot 4, utilize this mineral matter layer can protect insulating barrier 2, and there is certain insulating effect, also produce frictional resistance simultaneously, insulating barrier 2 prevents between heart yearn 1 and steel tube dirt-proof boot 4 wearing and tearing when because expand with heat and contract with cold, occurrence positions changes, wherein the preferred material of insulating barrier 2 is polytetrafluoroethylene, but also other insulating material, its thickness is between 1.1～2.0mm, guarantee not to be short-circuited between heart yearn 1 and steel tube dirt-proof boot 4
The material of heart yearn 1 is oxygen-free copper-wire, can be to screw and form in the shape of a spiral again after sub-thread copper rod or stranded copper wire line hinge twist into thigh.Can also be circular copper wire (or copper stranded conductor) or the conductor with identical functions, if this heart yearn 1 screws and forms in the shape of a spiral again after adopting line hinge to twist into thigh, the pitch screwing be 10-50 centimetre.
Steel tube dirt-proof boot 4 is for having the steel pipe of ferromagnetic property, and wall thickness is 1.5-3 centimetre.
In the utility model, tool kelvin effect accompanying-heat cable is in use evenly distributed on petroleum pipeline around, and be close to the surface of petroleum pipeline, that is to say, can or be banded on the outer wall of oil field petroleum pipeline accompanying-heat cable welding, and be welded to connect galvanic circle joint between the steel tube dirt-proof boot 4 of accompanying-heat cable tail end and heart yearn 1, make heart yearn and steel tube dirt-proof boot form a loop.Accompanying-heat cable is with together buried or built on stilts laying of petroleum pipeline, after laying completes, the heart yearn of accompanying-heat cable end 1 and steel tube dirt-proof boot 4 are welded to connect to conduction by loop joint, thereby companion's heat (heating) cable of kelvin effect and heating power supply form galvanic circle.When alternating current is in the time that cable passes through the steel pipe walls of steel tube dirt-proof boot 4, according to kelvin effect principle, electric current on heart yearn 1 equates with the size of current on steel tube dirt-proof boot 4, opposite direction, the magnetic direction producing is also contrary, affected by magnetic fields power, the electric current of steel tube dirt-proof boot 4 is confined to the very thin one deck of steel tube dirt-proof boot 4 inner surfaces, that is to say, electric current is not to flow along the even tube wall of steel tube dirt-proof boot 4, but the internal surface of steel pipe layer that concentrates on steel tube dirt-proof boot 4 passes through, and steel tube dirt-proof boot 4 inner surface resistance become large, generation current thermal effect, realize electric cable heating object, through heat conduction, the medium temperature in petroleum pipeline and petroleum pipeline is raise again.And steel tube dirt-proof boot 4 outer surface of steel tube voltages, electric current are zero, self form insulation system, the oil of extraction is carried safely and reliably in petroleum pipeline pipeline.As shown in Figure 2.
In the utility model, companion's heat (heating) cable of tool kelvin effect can adopt the method manufacture of prefabricate, also can adopt integral prefabricated method manufacture.
In sum, in the utility model, companion's heat (heating) cable of tool kelvin effect has following characteristics:
