Abstract
The utility model discloses a temperature-sensitive detection cable. The cable comprises a plurality of alloy conductors and two elastic metal conductors, wherein each alloy conductor is sequentially coated by a plastic foam layer and a silicone rubber insulation layer, and the conductors are stranded so as to form an insulation wire core; the two elastic conductors each is coated by an extruded temperature-sensitive insulation layer made of temperature-sensitive insulation material, and are stranded to form an insulation temperature sensitive component; the insulation wire cores are stranded into a harness, forming a cable core; a fireproof layer is arranged outside the cable core; the insulation temperature-sensitive components are arranged in gaps between the fireproof layer and the cable core; and the fireproof layer is coated by an extruded sheath layer. According to the utility model, the temperature-sensitive components are arranged among the insulation wire cores of the cable and electrically connected with an external controller, and when the cable is over-loaded or the environment temperature rises and reaches a certain temperature limit, the two elastic metal conductors are short-circuited, a signal is transmitted to the controller, and the controller cuts off the power supply according to corresponding instruction operation, thereby preventing the cable or equipment from being damaged; besides, the cable has good fireproof and anti-extrusion performance.
Description
Technical field
The utility model relates to power cable field, specifically a kind of temperature-sensitive detection streamer.
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 until the cable outlet fault rapidly 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, improve fire protecting performance and anti-extrusion performance, are the problems that industry is explored always.
The utility model content
The purpose of this utility model is to provide a kind of temperature-sensitive detection streamer; on the basis of common cable; add 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; cut off the electricity supply, protection cable or equipment are not compromised, and have improved simultaneously fireproofing of cable performance and anti-extrusion performance.
The technical solution of the utility model is as follows:
the temperature-sensitive detection streamer, it is characterized in that: include many alloy conductors and two elastic metallic conductors, described many alloy conductors are coated with respectively plastic foamed layer outward successively, mutually stranded formation insulated wire cores after silicone rubber insulation layer, described two elastic metallic conductors adopt respectively temperature-sensitive insulating material extrusion moulding that mutually stranded formation insulation temperature-sensing element after the temperature-sensitive insulating barrier is arranged outward, the mutual stranded bunchy of described insulated wire cores consists of cable core, cable core is provided with fireprotection layer outward, gap between fireprotection layer and cable core is equipped with the insulation temperature-sensing element, the outer extrusion moulding of fireprotection layer has restrictive coating.
Described temperature-sensitive detection streamer is characterized in that: described insulation temperature-sensing element is electrically connected to external controller.
The beneficial effects of the utility model:
Temperature-sensing element of the present utility model is arranged between the cable insulation core, and be electrically connected to external controller, when cable overload or ambient temperature raise the temperature limit that reaches certain, the temperature-sensitive insulating material of temperature-sensing element melts, and two elastic metallic conductors short circuit of temperature-sensing element passes to controller with signal, controller is according to the command adapted thereto action power dump, prevented that cable or equipment are damaged, in addition, cable fire-proof and anti-extrusion performance are good.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
referring to Fig. 1, the temperature-sensitive detection streamer, include many alloy conductors 1 and two elastic metallic conductors 2, many alloy conductors 1 are outer is coated with respectively plastic foamed layer 3 successively, the rear mutually stranded formation insulated wire cores of silicone rubber insulation layer 4, silicone rubber insulation layer is extruded on plastic extruder, can not occur coming unstuck, bottom pour ladle, the bad phenomenon such as flake, two outer temperature-sensitive insulating material extrusion moulding that adopt respectively of elastic metallic conductor 2 have the rear mutually stranded formation insulation temperature-sensing element of temperature-sensitive insulating barrier 5, the mutual stranded bunchy of insulated wire cores consists of cable core, cable core is provided with fireprotection layer 6 outward, effectively improved the fireproofing of cable performance, gap between fireprotection layer 6 and cable core is equipped with the insulation temperature-sensing element, the outer extrusion moulding of fireprotection layer 6 has restrictive coating 7.
The insulation temperature-sensing element is electrically connected to external controller, is convenient to detection.
