Abstract

The utility model discloses a thermosensitive color-changing light emitting cable which comprises a conductor, wherein a conductor shielding layer, an insulating layer, an insulating shielding layer, an inner jacket and an outer jacket are sequentially coated outside the conductor. A thermochromic light emitting protective layer is coated outside the outer jacket. According to the utility model, the thermochromic light emitting protective layer is further coated outside the outer jacket, wherein the protective layer mainly consists of electroluminescent powder, thermochromic powder and polyvinyl chloride resin or polyethylene resin and the like in a certain proportion. When leakage, short circuit or long-term overload operation of the cable occur to lead to local temperature rise of the cable, the protective layer on the surface of the cable emits light at night along with rise of temperature and the color of the cable changes at daytime so as to remind people that the cable is faulted, so that people can be immediately far from the faulted part and report to the cable maintenance crews for immediately solving faults. Thus, the operating state of the cable is effectively monitored, the safe operation of the cable is ensured, and the economic loss and casualties caused by accidents of short-circuit power failure, or even fire and the like are avoided.

Description

A kind of heat-sensitive variable colour luminous cable

Technical field

The utility model relates to the electric wire field, specifically refers to a kind of heat-sensitive variable colour luminous cable.

Background technology

Cable has the effect of signal transmission and electric energy transmitting, in installation and long-term use procedure, may damage because of external force, insulation and sheath are aging, long-term load running and the reasons such as environment and temperature make cable that the faults such as electric leakage or short circuit occur, and because the distance of cable laying is longer, some is also in the high-altitude, therefore difficulty is accurately promptly found trouble location, has caused larger difficulty also for the detection repair.Particularly in the concentration zones of cable laying, being difficult to which cable of difference directly perceived is to be in normal operating condition, and which cable is in the electric leakage state, and which cable is in the short circuit shut down condition.The running status of monitoring cable can not guarantee the safe operation of cable effectively, thereby causes accident, economic loss and the casualties such as short circuit outage even initiation fire.

The utility model content

The technical problems to be solved in the utility model provides a kind of running status of effectively monitoring cable, guarantees the safe operation of cable, avoid being short-circuited outage even initiation fire accident, the luminous cable of economic loss and casualties.

A kind of heat-sensitive variable colour luminous cable described in the utility model comprises conductor, successively from inner conductor shield, insulating barrier, insulation screen, inner sheath, the oversheath of outwards extruding, extrudes the luminous sheath of heat discoloration outside oversheath outside conductor.

The thickness of the luminous sheath of described heat discoloration is the 30%-50% of standard-required.

The beneficial effects of the utility model are:

The utility model is that the protective coverings of cable in general model and specification adds and squeezes the luminous sheath of one deck heat discoloration.When cable leaks electricity, short circuit or the operation of long-term g-load cause the cable local temperature to raise, the cable surface sheath is along with temperature raises at noctilucence, the phenomenon of change color occurs daytime, to remind people that cable breaks down, make people can be in time away from trouble location and report cable maintenance person to solve in time fault.The running status of monitoring cable has guaranteed the safe operation of cable effectively, avoid being short-circuited accident, economic loss and the casualties such as outage even initiation fire.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment:

As shown in Figure 1, a kind of heat-sensitive variable colour luminous cable described in the utility model, comprise conductor 1, outside conductor 1, successively from inner conductor shield 2, insulating barrier 3, insulation screen 4, inner sheath 5, the oversheath 6 of outwards extruding, outside oversheath 6, extrude the luminous sheath 7 of heat discoloration.

The luminous sheath 7 of heat discoloration described above is to be made of electroluminescent powder, heat discoloration powder and Corvic or polyvinyl resin.Described electroluminescent powder is a kind of fluorescent material with electroluminescence; Described heat discoloration powder is a kind of reversible heat discoloration material of microencapsulation, claim again warm variable pigments or temperature-sensitive powder, particle is spherical shape, average diameter is 2～7 microns, inside is electrochromic substance, the outside be thick layer approximately 0.2～0.5 micron can not dissolve the transparent outer cover that also can not melt, can be with the rising of temperature, descending, reversible color occurs.

The material of the luminous sheath 7 of heat discoloration is, 100 parts of Corvics, 1.3～2.2 parts in heat discoloration powder, 0.1～0.5 part of temperature-sensitive luminescent powder, 20～35 parts in misery 12 fat of O-phthalic, 15～35 parts in misery 11 fat of O-phthalic, 0.5～4.5 part of three salt stem lead sulfate, 0.5～2.5 part of disalt stem lead sulfate, 1.5～2.0 parts of barium stearates, 0.1～0.5 part of charge compensation agent, 3～10 parts of fillers, 0.05～0.10 part of colouring agent, 0.3～0.5 part in the bimodal class fluorescent material of rare earth, 0.3～0.5 part of diphenol propane (bisphenol-A), preparation technology adopts the general CABLE MATERIALS technique that is mixed with.By this kind CABLE MATERIALS being extruded in the outermost layer of electric wire, in the protection cable, when leak electricity, the reasons such as short circuit and electric current surge cause a serious accident and can change the cable outer layer color or send light before.

The process that extrudes of the luminous sheath 7 of the heat discoloration in the utility model is: at first the materials such as heat discoloration powder, electroluminescent powder are added by a certain percentage in the cable cover(ing) prescription of polyvinyl chloride resin main body, reach electric, the mechanical performance and the reprocessing technique performance that meet CABLE MATERIALS, processing temperature remains on below 200 ℃, the highest not above 230 ℃, and heated time should be not long, is generally about 10 minutes.The thickness of the luminous sheath 7 of this heat discoloration is 30%～50% of standard-required.

The utility model provides a kind of heat-sensitive variable colour luminous cable version and implementation method; the above only is preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
