Abstract
The utility model discloses a kind of heat discoloration early warning cable, power cable technical field, solve cable in conventional art poor without colour change function, heat resistance, without the problem of warning function, comprise the wire that some naked coppers are stranded, described wire is wrapped with insulating barrier and forms conductor, some temperature sensing springs are provided with between described conductor, Mica tape layer is provided with outside described conductor, copper tin braid is provided with outside described mica lapping layer, be provided with overcoat outside described copper tin braid, described overcoat surface is provided with fluorescence photochromic layer.The utility model provides a kind of cable with heat discoloration warning function, avoids the problem that cable is short-circuited because overloading, and simultaneously when temperature is too high, is changed by the color of cable outer layer, gives the replacing of workmen to cable and provides convenient.The utility model practical value is high, can be widely used in power cable technical field.
Description
Technical field
The utility model relates to power cable technical field, specifically, particularly relates to a kind of heat discoloration early warning cable.
Background technology
Cable is a part indispensable in daily life, general cable is primarily of the cable heart, insulating barrier, braid and protective jacket composition, wherein insulating barrier and protective jacket mainly adopt polyvinyl chloride, cross-linked polyolefin, this type of material is under high temperature occasion, due to cable load operation and hot environment, cable is easily made to be short-circuited, the fault such as aging, and this type of cable does not possess colour change function, when an error occurs, the change of color can not be there is in cable according to the change of ambient temperature, the function of early warning cannot be played, and then reduce the replacing efficiency of cable.
Summary of the invention
The utility model discloses a kind of heat discoloration early warning cable, for solve cable in conventional art poor without colour change function, heat resistance, without the problem of warning function.
The utility model is achieved through the following technical solutions:
A kind of heat discoloration early warning cable, comprise the wire that some naked coppers are stranded, described wire is wrapped with insulating barrier and forms conductor, some temperature sensing springs are provided with between described conductor, Mica tape layer is provided with outside described conductor, be provided with copper tin braid outside described mica lapping layer, be provided with overcoat outside described copper tin braid, described overcoat surface is provided with fluorescence photochromic layer.
Described fluorescence photochromic layer is temperature-sensitive Masterbatch.
Described fluorescence photochromic layer can according to different temperature range variable colors.
Described fluorescence photochromic layer manifests from night by day differently distinguishes look.
Filler is provided with between described conductor and described Mica tape layer.
Described filler is expansion material.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by adding temperature-sensitive Masterbatch at fluorescence photochromic layer, according to different temperature range variable colors, manifest different colors with night by day, still can clearly recognize in different environments, play the function of early warning, prevent from causing mechanical damage to cable; And when high temperature, fluorescence photochromic layer occur specific can discrimination color, the replacing for cable provides index directly perceived, decreases the incidence of accident; Set up temperature sensing spring between the conductors, when cable load operation, temperature sensing spring expands, and makes the spaced apart between conductor simultaneously, increases, and avoids wire load comparatively large, the situation of cable short circuit occurs.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation in the utility model front.
In figure: 1, wire; 2, insulating barrier; 3, temperature sensing spring; 4, mica lapping layer; 5, copper tin braid; 6, overcoat; 7, fluorescence photochromic layer; 8, filler.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of heat discoloration early warning cable, comprise the stranded wire of some naked coppers 1, described wire 1 is wrapped with insulating barrier 2 and forms conductor, some temperature sensing springs 3 are provided with between described conductor, Mica tape layer 4 is provided with outside described conductor, be provided with copper tin braid 5 outside described mica lapping layer 4, be provided with overcoat 6 outside described copper tin braid 5, described overcoat 6 surface is provided with fluorescence photochromic layer 7.
Described fluorescence photochromic layer 7 is temperature-sensitive Masterbatch.
Described fluorescence photochromic layer 7 can according to different temperature range variable colors.
Described fluorescence photochromic layer 7 manifests from night by day differently distinguishes look.
Filler 8 is provided with between described conductor and described Mica tape layer 4.
Described filler 8 is expansion material.
The utility model provides a kind of cable with heat discoloration warning function, avoids the problem that cable is short-circuited because overloading, and simultaneously when temperature is too high, is changed by the color of cable outer layer, gives the replacing of workmen to cable and provides convenient.The utility model practical value is high, can be widely used in power cable technical field.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
