Description
Technical Field
The utility model relates to a fire-retardant fire-resistant flexible cable of reversible discolouration type of temperature sensing can distinguish through discolouing when the cable generates heat.
Background
Telecommunication operators use a large amount of communication power supply wires in a machine room, and the problem of cable heating is mainly the problem of more feedback in the use process. The heating factors of the cable are many, such as the laying environment, the laying mode, the type selection of the cable and the like, and the heating aggregation of the cable is often influenced by small factors, so that the performance of the cable is influenced, and great potential safety hazards are brought. When communication power supply cable lays, generally tie the cable together and lay perpendicularly or the level, because the cable is mostly black, and is complicated intensive again, hardly finds concrete which circuit takes place the problem when the problem appears.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a fire-retardant fire-resistant flexible cable of reversible discolour type of temperature sensing is provided, this cable can show the condition of generating heat of cable obviously, high-efficiently.
In order to solve the technical problem, the temperature-sensing reversible color-changing flame-retardant fire-resistant flexible cable comprises a plurality of wire cores inside, wherein each wire core comprises a conductor, a high-heat-conductivity mineral fireproof layer is arranged outside each conductor, and a high-heat-conductivity mineral composite insulating layer is arranged outside each high-heat-conductivity mineral fireproof layer; the sinle silk has the filling layer outward, the filling layer comprises the netted filling rope of metal, the filling layer is formed around the covering through the fire-retardant area of metal outward, be the restrictive coating that discolours around the covering outside.
When the conductor generates heat, the high heat conduction material (metal mesh, ultra-thin metal fire-retardant area etc.) is changed into in the stranding packing and band, and the heat that the sinle silk produced carries out the heat transfer to the omnidirectional through the filling layer of the netted filling rope of metal, but the fire-retardant area of metal around the package efficient transmission gives the sheath heat to more be favorable to the change of sheath experience temperature and then the production warning that discolours.
Preferably, the high-thermal-conductivity mineral fireproof layer material is a mica tape, the high-thermal-conductivity mineral composite insulating layer material is ceramic silicone rubber, and the metal flame-retardant tape is a copper tape or an alloy tape.
The utility model discloses all use high thermal conductivity material from insulating material, packing, band, sheath, make between each structure transmission heat more high-efficient, sensitive, shorten the fault feedback time. The used sheath material has more obvious warning effect, high efficiency and repeated use.
The cable warning has the advantages of quick response time, obvious effect, reversible color and repeated recycling. The cable is in normal safe temperature range in the use, and the colour is as good as under the conventional state, when surpassing critical safe temperature, along with the gradual rise of temperature colour gradually becomes lighter, until colourless, can judge temperature and fault degree according to the colour depth. The color-changing sheath layer is a reversible color-changing sheath layer, after the fault is eliminated, the temperature is recovered to the safety limit, the color is changed back to the original color, and the process is reversible and can be used repeatedly in a large amount. Compared with the traditional product, the cable is safer, has larger current-carrying capacity and more excellent performance.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the temperature-sensitive reversible color-changing flame-retardant fire-resistant flexible cable includes a plurality of wire cores (e.g., two wire cores in fig. 1) inside, the wire cores include a flexible conductor 1, a mica tape is outside the conductor 1, and a ceramic silicone rubber is outside the mica tape.
The sinle silk has filling layer 4 outward, filling layer 4 comprises the netted filling rope of metal, and the netted filling rope of metal is the same with traditional netted filling rope structure of PP, and metal mesh (wire is woven) can the omnidirectional carry out heat transfer.
The filling layer 4 is wrapped by a copper belt (or an alloy belt) to form a wrapping layer 5, and the wrapping layer 5 is a color-changing sheath layer 6.
The color-changing sheath layer 6 is a reversible color-changing sheath layer, which can be an insulating layer material for cables capable of displaying temperature change disclosed in patent document with the publication number of CN105489280B, or is prepared by mixing temperature-sensitive color-changing powder (prepared by an electron transfer organic compound) into S-PVC (flexible polyvinyl chloride), and when the sheath is made, the color-changing powder is mixed into special color master batch, and the dosage of the color-changing powder is 0.5-1.0% of the plastic. The color-changing powder is fully and uniformly mixed with the color master batch and the plastic particles (a small amount of white oil can be used during mixing) and then is pressed.
When the cable is used, the color of the cable is not different from that of the cable in a conventional state within a normal safe temperature range, and when the critical safe temperature is exceeded, the color of the cable gradually becomes lighter along with the gradual rise of the temperature until the cable is colorless, and the temperature and the fault degree can be judged according to the color depth. After the fault is eliminated, the temperature is recovered to the safety limit, the color is changed back to the original color, and the process is reversible and can be repeatedly used in a large amount.
When the conductor generates heat, the heat that the sinle silk produced carries out the heat transfer to the omnidirectional through the filling layer of the netted filling rope of metal, but the fire-retardant area of metal is around package efficient transmission for the sheath heat to more be favorable to the change of sheath sensation temperature and then the production warning that discolours.
The above-mentioned embodiment does not limit the utility model in any way, and all the technical solutions that adopt the mode of equivalent replacement or equivalent transform to obtain all fall within the protection scope of the utility model.
