Abstract
The utility model discloses a self-cooling power cable. The power cable comprises a plurality of cable cores, wherein the plurality of cable cores are arranged around a sealed flexible metal pipe which can be introduced with a cooling medium; and a temperature measurement wire is arranged in the flexible metal pipe. According to the self-cooling power cable, the sealed flexible metal pipe is placed in the middle of an original product, and a temperature-measuring wire is placed in the metal pipe and used for measuring the actual temperature of the whole cable; and water flow can pass through the metal pipe. When the temperature of the cable reaches a preset alarm temperature, alarm equipment connected with the temperature measuring wire automatically sends out alarms and water is injected into the metal pipe at first time, so that the temperature of the cable can be quickly reduced. According to the self-cooling power cable, the cable is prevented from being broken down or burnt due to temperature rise, so that a fire disaster caused by over-high temperature of the cable can be prevented, and the product can be applied to all places with electrical equipment and has good practicality and economy.
Description
Technical field
The utility model belongs to the power cable technical field, is 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.
The utility model content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model provides a kind of from lowering the temperature power cable, 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 adopted in the utility model 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 utility model 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.

Fig. 2 is the structural representation from the power cable of lowering the temperature.
Embodiment
Further illustrate the utility model below in conjunction with accompanying drawing, this embodiment is implemented under take technical solutions of the utility model as prerequisite, should understand these modes and only be used for explanation the utility model and be not used in restriction scope of the present utility model.
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.
