Abstract
The utility model discloses a kind of automatic control heat tracing cable structure, automatic control accompanying-heat cable of the present utility model can be accomplished to allow heating system deacclimatize heated object system, copper stranded conductor is power source bus, is evenly crowded with the heating core material of conducting polymer composite between copper stranded conductor and insulated tube.When bus switches on power, electric current flows transversely through the heating core material between two buses, and core material is heated up, and its resistance increases thereupon automatically.When core material temperature is raised to certain value, resistance arrives greatly the degree almost blocking electric current, and core material temperature no longer rises.Meanwhile, core material is by sheath to the heat transfer of heated object system, and temperature declines, and when temperature drops to certain value, resistance reduces gradually, and core material heating temp rises.So move in circles, just can maintain heated object system steady temperature.
Description
Technical field
The utility model relates to field of cables, relates to a kind of automatic control heat tracing cable structure specifically.
Background technology
Automatic temperature-controlled heat tracing cable makes heater with a kind of conducting polymer composite, its heating power, automatically can adjust, controls self each point temperature and keep constant temperature.Traditional heat tracing cable structure uses invariable power heater, and it needs heated object to deacclimatize the mode of heating of heater.Traditional accompanying-heat cable does not allow repeatedly juxtaposition to use, and even there will be heat spot and burn the phenomenon of cable in heating process.
Utility model content
For deficiency of the prior art, the technical problems to be solved in the utility model there are provided a kind of automatic control heat tracing cable structure, temperature during this construction of cable energy volitional check heating, and can with the automatic regulation output power of the variations in temperature of heated object system.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of automatic control heat tracing cable structure, it comprises puts outermost reinforced sheath, inside by reinforced sheath, be coated with braid, inner restrictive coating, main insulating layer successively, described main insulating layer outer wall is wound with heating wire uniformly, three power source buss are coated with in main insulating layer inside, every root power source bus appearance is all surrounded by insulated tube, described power source bus is copper stranded conductor, has evenly been crowded with the heating core material be made up of conducting polymer composite in the gap between copper stranded conductor and insulated tube.
Further, described insulating barrier outer wall is provided with the groove mated with heating wire, the half-section of heating wire embeds in groove.
Further, described braid is that copper material is made.
Further, described braid is diamond weave structure.
Further, the often bundle copper cash of described braid is also provided with one deck fiber braiding layer outward.
Relative to prior art, the beneficial effects of the utility model are: automatic control accompanying-heat cable of the present utility model can be accomplished to allow heating system deacclimatize heated object system, copper stranded conductor is power source bus, is evenly crowded with the heating core material of conducting polymer composite between copper stranded conductor and insulated tube.When power source bus switches on power, electric current flows transversely through the heating core material between power source bus, and core material is heated up, and its resistance increases thereupon automatically.When core material temperature is raised to certain value, resistance arrives greatly the degree almost blocking electric current, and core material temperature no longer rises.Meanwhile, core material is by sheath to the heat transfer of heated object system, and temperature declines, and when temperature drops to certain value, resistance reduces gradually, and core material heating temp rises.So move in circles, just can maintain heated object system steady temperature.

Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is explained in detail.
Please refer to accompanying drawing 1, a kind of automatic control heat tracing cable structure of the present utility model, it comprises puts outermost reinforced sheath 1, inside by reinforced sheath 1, be coated with braid 2, inner restrictive coating 3, main insulating layer 5 successively, described main insulating layer outer wall is wound with heating wire 4 uniformly, three power source buss 7 are coated with in main insulating layer 5 inside, every root power source bus 7 appearance is all surrounded by insulated tube 6, described power source bus 7 is copper stranded conductor, has evenly been crowded with the heating core material be made up of conducting polymer composite in the gap between copper stranded conductor and insulated tube 6.
Please refer to accompanying drawing 2 ~ 3, described insulating barrier 5 outer wall is provided with the groove 51 mated with heating wire 4, the half-section of heating wire 4 embeds in groove 51, heating wire 4 coiling more for convenience, can better heat conduction at adstante febre, avoid, because heating wire is wound around uneven and local heating produces too high heat, cable being damaged.
Automatic control accompanying-heat cable of the present utility model can be accomplished to allow heating system deacclimatize heated object system, and copper stranded conductor is power source bus 7, is evenly crowded with the heating core material of conducting polymer composite between copper stranded conductor and insulated tube.When bus switches on power, electric current flows transversely through the heating core material between two buses, and core material is heated up, and its resistance increases thereupon automatically.When core material temperature is raised to certain value, resistance arrives greatly the degree almost blocking electric current, and core material temperature no longer rises.Meanwhile, core material is by sheath to the heat transfer of heated object system, and temperature declines, and when temperature drops to certain value, resistance reduces gradually, and core material heating temp rises.So move in circles, just can maintain heated object system steady temperature.
Please refer to accompanying drawing 1 and accompanying drawing 4, described braid 2 is made for copper material, described braid 2 is diamond weave structure, the often bundle copper cash 21 of described braid 2 is outer is also provided with one deck fiber braiding layer 22, fiber braiding layer 22 is played a supporting role, make braid 2 not yielding, structure is more stable, meanwhile, because copper cash 21 is embedded in fiber braiding layer 22, can not damage other structure of cable, simultaneously, copper cash 21 can play shielding action, does not need to do one deck screen more separately, therefore can save material.
The foregoing is only preferred implementation of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
