Description
Technical field
The utility model belongs to electric heating element field, particularly relates to a kind of warm carbon fiber heat tracing belt of limit certainly based on PTC effect.
Background technology
Electric tracing utilizes electric tracing equipment to be heat energy by electric energy conversion exactly, by direct or indirect heat exchange, supplement by the hot equipment of companion by insulation material the heat that loses, and adopt temperature to control, reach and follow the tracks of and control the temperature of medium in the hot equipment of companion, make it to maintain in a reasonable and economic level.In the past, steam tracing is a kind of main heat preserving mode all the time.Its operation principle is dispelled the heat by steamtraced piping with the thermal loss of supplementary insulation pipeline.Because the heat dissipation capacity of steam is wayward, its insulating efficiency is in a lower level all the time.20 century 70s, american energy industry carrys out the imagination of alternative steam tracing with regard to proposition electric tracing scheme.At the beginning of the eighties at the end of the seventies, electric tracing technology extensively promoted by a lot of industrial departments comprising energy industry, replaces steam tracing with electric tracing comprehensively.
The electric tracing product ubiquity of current employing exothermic material resistance instability, the problems such as gradient of temperature is uneven, poor reliability, and useful life is short.
Utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of structure simple, exothermic material resistance stabilization, and gradient of temperature is even, and reliability is high, the warm carbon fiber heat tracing belt of limit certainly based on PTC effect of long service life.
For solving the problems of the technologies described above, the utility model realizes like this.
Based on the warm carbon fiber heat tracing belt of limit certainly of PTC effect, it comprises the conductive cores of two carbon fibers be set parallel to each other and tin-coated copper wire stranding; Be provided with outside described conductive cores and be covered with ptc layer; Thermally conductive insulating layer is provided with outside described ptc layer; Watertight composition is provided with outside described thermally conductive insulating layer; Polyethylene insulation sheath is provided with outside described watertight composition; Metal screen layer is provided with outside described polyethylene insulation sheath; Polyethylene insulation outer jacket is provided with outside described metal screen layer.
As a kind of preferred version, the utility model is wound around metal electric heated filament layer at described conductive cores external spiral.
It is simple that the utility model has structure, exothermic material resistance stabilization, and gradient of temperature is even, the features such as reliability is high, long service life.
Compared with prior art, the utility model tool has the following advantages.
(1) ribbon heater is corresponding is had automatic regulation output power by companion's hot system, therefore can not burn because of self-heating, but because actual needs heat compensates.
(2) low-temperature condition, Fast starting, homogeneous temperature, because each local all can be accompanied the variations in temperature at heat place automatically to regulate because of it.
(3) simple installation, safeguard simple, operation and maintenance expense is low.
(4) safe and reliable, purposes is wide, and free from environmental pollution, the life-span is long.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Protection range of the present utility model is not only confined to the statement of following content.
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1, conductive cores; 2, ptc layer; 3, thermally conductive insulating layer; 4, watertight composition; 5, polyethylene insulation sheath; 6, metal screen layer; 7, polyethylene insulation outer jacket; 8, metal electric heated filament layer.
Embodiment
Shown in Figure 1, a kind of warm carbon fiber heat tracing belt of limit certainly based on PTC effect, it comprises the conductive cores 1 of two carbon fibers be set parallel to each other and tin-coated copper wire stranding; Be provided with outside described conductive cores 1 and be covered with ptc layer 2; Thermally conductive insulating layer 3 is provided with outside described ptc layer 2; Watertight composition 4 is provided with outside described thermally conductive insulating layer 3; Polyethylene insulation sheath 5 is provided with outside described watertight composition 4; Metal screen layer 6 is provided with outside described polyethylene insulation sheath 5; Polyethylene insulation outer jacket 7 is provided with at described metal screen layer 6.The utility model is wound around metal electric heated filament layer 8 at described conductive cores 1 external spiral.
PTC effect and positive temperature coefficient effect refer in particular to resistivity of material raise along with temperature and increase, and in the characteristic that uniform temperature compartment resistivity sharply increases.
The utility model is between two parallel metal buses, extrude the core ribbon that one deck ptc material makes uniformly.Ptc material is through melt extruding, after cooling and shaping, and dispersion carbon particle wherein forms countless very thin conduction charcoal network.When they are connected across on two parallel bus, just form the PTC shunt circuit of core ribbon.When two buses of cable one end and power supply are connected, electric current flows transversely through ptc layer from a bus and arrives another root bus formation shunt circuit.PTC layer is exactly the resistance heater be connected in parallel on continuously between bus, and electric energy conversion is become heat energy, carries out tracing thermal-insulating to operating system.When core ribbon temperature is raised to corresponding high resistance area, resistance arrives greatly the degree almost blocking electric current, and the temperature of core ribbon will reach high limit and no longer raise (i.e. automatic temp limit).Meanwhile, core ribbon is conducted heat to the heated object system that temperature is lower by sheath, and the heat reaching unit interval transmission during stable state equals the electrical power of cable.The power output of cable is mainly controlled by the temperature of diabatic process and heated object system.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
