Abstract
The invention discloses a self-cooling power cable, which comprises a plurality of cable cores, wherein the plurality of cable cores are arranged around a sealed flexible metal tube into which cooling medium can be introduced; and a temperature measuring line is arranged in the flexible metal tube. According to the self-cooling power cable disclosed by the invention, the sealed flexible metal tube is put in the middle of the original product; the temperature measuring line is put in the metal tube and used for detecting the practical temperature of the whole cable; water flow possibly flows through the metal tube; once the temperature of the cable is up to the pre-set alarm temperature, alarm equipment connected to the temperature measuring line gives an alarm automatically and injects water in the metal tube at the first time to reduce the temperature; therefore, the temperature of the cable is rapidly decreased; breakdown and burnout of the cable caused by temperature increasing can be avoided; fire disasters caused by temperature increasing of the cable can be prevented; and the self-cooling power cable disclosed by the invention can be used in all places of electric equipment and has good practicability and economy.
Description
Technical field
The invention belongs to the power cable technical field, be specifically related to a kind of from lowering the temperature power cable.
Background technology
Power cable is for being connected between high-voltage power transmission line road and the power consumption equipment, plays a part power transmission, and power cable is widely used in factory, school, government, petrochemical industry, market etc. place.
As shown in Figure 1, power cable commonly used generally is comprised of conductor 4, insulating barrier 3, twining package tape 2 and oversheath 1, and the cable core number is not waited to 5 cores by 1 core, and the shape of conductor 4 can be circle, fan-shaped or semicircle, according to the needs of field of employment, can also make the steel-tape armouring type.Along with power consumption equipment continuous increase in the line, the electric current that cable bears is also increasing, secondly cable is along with the passing of service time, there are the phenomenons such as aging in cable, and its ampacity is also incited somebody to action reduction in various degree, in case electric current exceeds rated current-carrying capacity, cable will generate heat, cable will puncture, burn after reaching uniform temperature, will cause fire when serious, and common power cable just can not be realized reaching from cooling function from measuring.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the purpose of this invention is to provide a kind of power cable of certainly lowering the temperature, so that it has real-time detection cable temperature function, and can provide necessary condition for realizing the cable cooling.
Technical scheme: for achieving the above object, the technical solution used in the present invention is as follows:
A kind of from lowering the temperature power cable, comprise some cables core; Described some cables core are provided with the thermometric line around the sealed soft metal tube setting that can pass into coolant in flexible metallic hose.
Described cable core has 1 ~ 5, is located in the oversheath and by twining package tape or steel-tape armouring to wrap up.
Described cable core is comprised of the conductor of insulating barrier parcel; Being shaped as of described conductor is circular, fan-shaped or semicircle.
Described thermometric line links to each other with the controller of peripheral hardware, and described controller links to each other with alarm.
Beneficial effect: compared with prior art, of the present invention from lowering the temperature power cable, sealed soft metal tube of placement in the middle of original product is placed a thermometric line in the metal tube, be used for surveying the actual temperature of whole cable, may pass through current in the metal tube.After in case cable temperature reaches the alarm temperature of setting, connect the warning device of thermometric line with automatic alarm, and the very first time water filling in the metal tube is reduced temperature, realize rapidly the cooling of cable.Realized not can Yin Wendu raise and cause cable puncture, burn, guaranteed the fire that cable does not cause because temperature rise is too high, this product can apply to the place of all power consumption equipments.Have good practicality and economy.
Description of drawings
Fig. 1 is the structural representation of existing HDMI high-definition multimedia cable;
Fig. 2 is the structural representation from the power cable of lowering the temperature.
Embodiment
Further illustrate the present invention below in conjunction with accompanying drawing, this embodiment is implemented under take technical solution of the present invention as prerequisite, should understand these modes and only be used for explanation the present invention and be not used in and limit the scope of the invention.
As shown in Figure 2, the power cable of certainly lowering the temperature comprises being located in the oversheath 1 and by 1 ~ 5 cable core, flexible metallic hose 5 and the thermometric line 6 of twining package tape (cable powered by conventional energy) or steel-tape armouring (steel-tape armouring type power cable) 2 parcels; Every cable core forms by the conductor 4 that insulating barrier 3 wraps up, and being shaped as of conductor 4 is circular, fan-shaped or semicircle.Each bar cable core arranges around flexible metallic hose 5, is provided with thermometric line 6 in flexible metallic hose 5.Flexible metallic hose 5 is for passing into the sealed soft metal tube of coolant (water).
For realizing that thermometric line 6 can link to each other with the controller of peripheral hardware from cooling, this controller links to each other with alarm, and simultaneously, flexible metallic hose 5 can communicate with the water source of peripheral hardware, realizes automatically control cooling.
This power cable of certainly lowering the temperature is placed a sealed soft metal tube in the middle of original product, place a thermometric line in the metal tube, is used for surveying the actual temperature of whole cable, may pass through current in the metal tube.After in case cable temperature reaches the alarm temperature of setting, connect the warning device of thermometric line with automatic alarm, and the very first time water filling in the metal tube is reduced temperature, realize rapidly the cooling of cable.Realized not can Yin Wendu raise and cause cable puncture, burn, guaranteed the fire that cable does not cause because temperature rise is too high, this product can apply to the place of all power consumption equipments.
