Abstract
The utility model discloses a temperature-sensitive power cable including a plurality of conductors and two elastic metal conductors. Temperature-sensitive insulation layers are formed outside the two elastic metal conductors through extrusion molding by adopting temperature-sensitive insulation material and then the two elastic metal conductors are twisted with each other, thereby forming an insulation temperature-sensitive element. The conductors are provided with insulation layer formed through extrusion molding and then twisted together, thereby forming an insulation wire core. The insulation temperature-sensitive element is arranged in gaps among the conductors. The conductors are provided with a sheath formed through extrusion molding. According to the utility model, the temperature-sensitive element is arranged in the insulation wire core of the temperature-sensitive power cable and is connected with an external controller electrically. When the temperature-sensitive power cable overloads or the environmental temperature rises to a certain temperature limit, the temperature-sensitive insulation material of the temperature-sensitive element is melted. The two elastic metal conductors of the temperature-sensitive element short out. A signal is transmitted to the controller. The controller cuts off power supply according to corresponding instruction actions, thereby preventing the temperature-sensitive power cable or a device from being damaged.
Description
Technical field
The utility model relates to the power cable field, specifically is a kind of temperature-sensitive power cable.
Background technology
The insulation of common power cable and sheath material are generally polyvinyl chloride, cross-linked polyolefin etc., and these materials can be aging rapidly until the cable outlet fault in cable overload or high temperature occasion etc.How to avoid cable in overload or the safe operation of high temperature occasion, protection and other equipment are not damaged, and are the problems that industry is explored always.
The utility model content
The purpose of the utility model provides a kind of temperature-sensitive power cable, on the basis of common cable, adds temperature-sensing element; When the temperature rise of cable overload or ambient temperature reach the temperature that cable can bear; The temperature-sensing element action is cut off the electricity supply, and protection cable or equipment are not compromised.
The technical scheme of the utility model is following:
A kind of temperature-sensitive power cable; Include many conductors and two elastic metallic conductors; It is characterized in that: described two elastic metallic conductors adopt temperature-sensitive insulating material extrusion moulding that mutually stranded formation insulation temperature-sensing element behind the temperature-sensitive insulating barrier is arranged outward respectively; Described many conductors have mutually stranded formation insulated wire cores behind the insulating barrier through extrusion moulding respectively outward, and in the gap of described insulation temperature-sensing element between many conductors, described many conductors are outer to have sheath through extrusion moulding.
Described temperature-sensitive power cable is characterized in that: described two elastic metallic conductors are steel wire.
Described temperature-sensitive power cable is characterized in that: described insulation temperature-sensing element is electrically connected with external controller.
The beneficial effect of the utility model:
The temperature-sensing element of the utility model is arranged between the cable insulation core; And be electrically connected with external controller, when cable overload or ambient temperature raise the temperature limit that reaches certain, the temperature-sensitive insulating material of temperature-sensing element melted; Two elastic metallic conductors short circuit of temperature-sensing element; Signal is passed to controller, and controller has prevented that according to the command adapted thereto action power dump cable or equipment are damaged.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1; A kind of temperature-sensitive power cable; Including the outer temperature-sensitive insulating material extrusion moulding that adopts respectively of three conductors 1 and 2, two elastic metallic conductors of two elastic metallic conductors 2 has mutually stranded formation insulation temperature-sensing element behind the temperature-sensitive insulating barrier 3, and three conductors 1 are outer to have mutually stranded formation insulated wire cores behind the insulating barrier 4 through extrusion moulding respectively; In the gap of insulation temperature-sensing element between three conductors 1, through extrusion moulding sheath 5 is arranged outside three conductors 1.
Two elastic metallic conductors 2 are steel wire; The insulation temperature-sensing element is electrically connected with external controller.
The manufacture craft of the utility model is following:
Combine the actual conditions conductor to adopt suitable conductor according to the GB/T3956 regulation, conductor should be bright and clean, phenomenons such as no burr, overlap.Insulating barrier is extruded on plastic extruder, can not occur coming unstuck, bad phenomenon such as bottom pour ladle, flake.The temperature-sensitive conductor adopts elastic metallic material such as steel wire etc.; The temperature-sensitive conductor coats the temperature-sensitive insulating barrier outward; The temperature-sensitive insulating barrier can not have phenomenons such as bottom pour ladle, according to the temperature of the long-term permission operation of cable the temperature of temperature-sensing element can be set, as 70 ℃, 90 ℃ etc.; Then that temperature-sensitive unit original paper is stranded, twisting pitch should meet process stipulation.Select suitable cabler that cable core and temperature-sensitive original paper are carried out stranding, the direction of stranding is a dextrad.The stranding lay ratio will comply with relevant regulations, and the speed of each parts also will be followed the pertinent regulations of operation card.The extrusion of sheath is with the extrusion of insulating barrier.
