Abstract
The utility model discloses a kind of cable of certainly lowering the temperature with persistent loop structure, comprise polyether-ether-ketone liner core, three heat radiation cavitys along annular space distribution are provided with in polyether-ether-ketone liner core, the madial wall of heat radiation cavity near polyether-ether-ketone liner core center is provided with projection, be provided with power conductor in projection, the external polyether-ether-ketone insulating barrier of power guide forms kinetic insulation core; Polyether-ether-ketone liner core is coated with powder separator, polyether-ether-ketone external sheath layer outward successively, polyether-ether-ketone external sheath layer outer wall is interval with annular boss, be provided with looping pit in annular boss, on annular boss sidewall, opposite side is respectively equipped with recirculated water water inlet, recirculated water delivery port.The utility model is by being distributed in independently in cavity by three power conductors, the impact that heats up of mutual electric current is less; Annular boss can as heat radiation terrace with edge, and heat radiation cavity can coordinate cooling holes water filling or other cooling liquid to carry out fast cooling protection cable core as required, extends cable useful life.
Description
technical field:
The utility model relates to electric wire, particularly relates to a kind of cable of certainly lowering the temperature with persistent loop structure.
background technology:
The power cable of the motor in high-temperature work environment, high-temperature baking cannot be born, the electric current that power cable bears is also increasing, secondly cable is along with the passing of service time, and cable exists the phenomenons such as aging, and its ampacity is also by reduction in various degree, once electric current exceeds rated current-carrying capacity, cable will generate heat, and after reaching uniform temperature, cable will puncture, burn, and fire will be caused time serious often to occur.
Therefore, need the construction of cable reasonable in design to enable effective radiating and cooling, thus extend the useful life of cable.
utility model content:
The purpose of this utility model is to provide a kind of cable of certainly lowering the temperature with persistent loop structure, and novel in structural design, can use for a long time, lower the temperature fast and effectively, increase the service life in hot environment.
The technical solution of the utility model is as follows:
With the cable of certainly lowering the temperature of persistent loop structure, it is characterized in that: comprise polyether-ether-ketone liner core, three heat radiation cavitys along annular space distribution are provided with in polyether-ether-ketone liner core, the madial wall of heat radiation cavity near polyether-ether-ketone liner core center is provided with projection, be provided with power conductor in projection, the external polyether-ether-ketone insulating barrier of power guide forms kinetic insulation core; Described polyether-ether-ketone liner core is coated with powder separator, polyether-ether-ketone external sheath layer outward successively, polyether-ether-ketone external sheath layer outer wall is interval with annular boss, looping pit is provided with in annular boss, on annular boss sidewall, side is provided with the recirculated water water inlet with looping pit UNICOM, and opposite side is provided with the recirculated water delivery port with looping pit UNICOM.
The described cable of certainly lowering the temperature with persistent loop structure, is characterized in that: described powder separator adopts refractory ceramics powder and silicate powder to be mixed according to equal proportion.
The utility model has the advantages that:
1, the utility model novel in structural design, by being distributed in by three power conductors independently in cavity, the impact that heats up of mutual electric current is less;
2, heat radiation cavity of the present utility model is not when temperature exceedes cable normal working temperature, can play the effect of heat radiation; Work long hours in hot environment, time core temperature exceedes cable normal working temperature, water filling or other cooling liquid in looping pit can be coordinated to carry out fast cooling, and protection cable core, extends the useful life of cable.
3, the utility model is equally also applicable to work in cold environment, can carry out warming temperature by filling heat-conductive wet goods medium in looping pit, the preference temperature of protection cable core work.
4, annular boss of the present utility model can, as heat radiation terrace with edge, coordinate blower fan etc. to carry out cable cooling.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
See accompanying drawing:
With the cable of certainly lowering the temperature of persistent loop structure, comprise polyether-ether-ketone liner core 1, three heat radiation cavitys 2 along annular space distribution are provided with in polyether-ether-ketone liner core 1, the madial wall of heat radiation cavity 2 near polyether-ether-ketone liner core center is provided with protruding 3, be provided with power conductor 4 in protruding 3, the outer polyether-ether-ketone insulating barrier 5 of power conductor 4 forms kinetic insulation core; Polyether-ether-ketone liner core 1 is outer is coated with powder separator 6, polyether-ether-ketone external sheath layer 7 successively, polyether-ether-ketone external sheath layer 7 outer wall is interval with annular boss 8, looping pit 9 is provided with in annular boss 8, on annular boss 8 sidewall, side is provided with the recirculated water water inlet 10 with looping pit UNICOM, and opposite side is provided with the recirculated water delivery port 11 with looping pit UNICOM.
Powder separator 6 adopts refractory ceramics powder and silicate powder to be mixed according to equal proportion.
