Abstract
The utility model discloses a heating cable used for the storing oil tank, the oil well-pipe and the oil pipeline. The utility model belongs to the technical field of the oil production's corollary equipment. Against the deficiencies of the prior art, a carbon fiber electric heating cable is provided that directly uses the AC dynamic power whose power frequency is 50HZ. The technical characters are that a conduction carbon fiber is connected with and is laid to the external surface of a dynamic power line served as a heating element; a conducting metal tightening clamp is adopted and makes the carbon fiber interconnect with the dynamic power line. The carbon fiber and the dynamic power line are formed into the carbon fiber electric heating cable. The advantages of the utility model are simple production, high intensity of product, oil proof, acid and alkali proof, corrosion proof, light weight and little investment. Without matching with a transform equipment of power supply, the conversion of heat efficiency can achieve as high as 98%. The utility model has wide serviceable range of voltage power, stable and reliable performance and long life. The utility model can be used for the heating and the heat insulation in the fields of oil field-wells, oil pipelines, storing oil tanks, rails, metallurgies and chemical industries and so on.
Description
Technical field
The utility model discloses a kind of heating cable that is used for oil storage tank, oil well oil conduit and oil pipeline, belong to Petroleum Production corollary equipment technical field.
Background technology
Kelvin effect electric-heating technology (the English SECT of abbreviation technology) is a kind of pipeline heating technique that middle nineteen sixties occurs.Initial stage is adopted power frequency (50Hz) alternating current, because of the low restriction that reaches electric current of AC impedance, can only be applicable to small-caliber steel pipe (1～2 inch), can not be directly used in the heating of large-diameter steel pipe.Thereby be used for the heating of large-diameter steel pipe, and must be at small-bore heating steel pipe of large-diameter steel pipe outside weld, heating small-bore heating steel pipe, indirect large-diameter steel pipe more earlier.This mode efficient is low, the investment height is eliminated.Then, intermediate frequency kelvin effect electric-heating technology has been used power electronic technology, has particularly adopted the IGBT power device.Thereby the heating in medium frequency power supply has reduced cost significantly, has also improved the frequency of output AC electricity simultaneously, has improved the AC impedance of steel pipe, makes intermediate frequency kelvin effect electric-heating technology can directly apply to the electric heating of large-diameter steel pipe.Above-mentioned mode of heating still exists power conversion loss, the deficiency that equipment has high input.
Summary of the invention
The utility model provides a kind of carbon fiber electrically heating cable of direct use 50Hz industrial frequency AC electrical source of power at the deficiency of prior art.
Technical characterictic of the present utility model is to connect in power power transmission line outside to lay conductive carbon fibre as heater, adopts the fastening card of metal of conduction that carbon fiber is connected with the power power transmission line, forms the carbon fiber electrically heating cable.
Below introduce structure of the present utility model in detail: a kind of carbon fiber electrically heating cable, constitute by the lead and the outer field restrictive coating of tape insulation layer, it is characterized in that forming electric heating body by the fastening card connection carbon fibre of conduction between the lead.
In the utility model when work,, according to the requirement of supply voltage, phase place and heating power, the specification of selecting to adapt to directly is laid in the oil pipe, and energized gets final product.
The utility model has overcome short, defective such as the heat efficiency is low, tensile strength is weak of the life-span of traditional heating cable, and stronger competitiveness is arranged on market, is top grade on the electric heating market.Advantage is reasonable in design, and manufacturing process is simple; Product strength height, oil resistant, acid and alkali-resistance, corrosion-resistant; In light weight, small investment does not need supporting power conversion device, and the heat efficiency is changed up to 98%; The voltage power scope of application is wide, stable and reliable working performance, and the life-span is long.Can be used for field heating and insulations such as oilfield, oil pipeline, oil storage tank, rail, metallurgy, chemical industry.
Description of drawings
Figure of description 1 is a structural representation of the present utility model.Among the figure: 1-lead, 2-fastening card, 3-carbon fibre, 4-restrictive coating, 5-insulating barrier.
Embodiment
Embodiment of the present utility model 1 is made up of two leads referring to accompanying drawing, is fit to the single phase alternating current power supply power supply.A kind of carbon fiber electrically heating cable is made of the lead 1 and the outer field restrictive coating 4 of tape insulation layer 5, it is characterized in that connecting carbon fibres 3 by the fastening card 2 of conduction between the lead 1 forms electric heating body.
Carbon fibre 3 places in the middle of the lead 1, also can apply the side at lead.
Among another embodiment of the present utility model, form, be fit to the three-phase alternating-current supply power supply by three leads.The outside that carbon fibre 3 is wrapped in lead 1 constitutes spiral, and two groups of adjacent carbon fibres 3 are sequence arrangement successively.
