Abstract
The utility model discloses a kind of cable of certainly lowering the temperature for steel works equipment, comprise polyether-ether-ketone liner core, the center of polyether-ether-ketone liner core is provided with thermometric core, three heat radiation cavitys along annular spread 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, power guide is external is coated with high temperature resistance glass fiber band lapping layer, polyether-ether-ketone insulating barrier formation kinetic insulation core successively; Liner core is coated with neatly rock layers, fire-retardant oxygen barrier lining, polyether-ether-ketone external sheath layer outward successively, polyether-ether-ketone external sheath layer is also provided with run through neatly rock layers, fire-retardant oxygen barrier lining, polyether-ether-ketone liner core and with heat radiation cavity UNICOM cooling holes.Three power conductors are distributed in independently in cavity by the utility model, and the impact that heats up of mutual electric current is less; 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 for steel works equipment.
background technology:
In iron and steel job shop, withdrawal straightening machine power is by motor driven, the power cable of motor cannot bear high-temperature baking, and the electric current that power cable bears is also increasing, and secondly cable is along with the passing of service time, there is the phenomenons such as aging in cable, its ampacity is also by reduction in various degree, once electric current exceeds rated current-carrying capacity, cable will generate heat, 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 for steel works equipment, 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:
For the cable of certainly lowering the temperature of steel works equipment, it is characterized in that: comprise polyether-ether-ketone liner core, the center of polyether-ether-ketone liner core is provided with thermometric core, three heat radiation cavitys along annular space distribution are provided with in the polyether-ether-ketone liner core of thermometric core periphery, 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, power guide is external is coated with high temperature resistance glass fiber band lapping layer, polyether-ether-ketone insulating barrier formation kinetic insulation core successively; Described polyether-ether-ketone liner core is coated with neatly rock layers, fire-retardant oxygen barrier lining, polyether-ether-ketone external sheath layer outward successively, polyether-ether-ketone external sheath layer is also provided with run through neatly rock layers, fire-retardant oxygen barrier lining, polyether-ether-ketone liner core and with heat radiation cavity UNICOM cooling holes.
The described cable of certainly lowering the temperature for steel works equipment, is characterized in that: described thermometric core is connected with alarm by controller.
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;
3, the utility model works long hours in hot environment, and time core temperature exceedes cable normal working temperature, cooling holes water filling or other cooling liquid can be coordinated to carry out fast cooling, and protection cable core, extends the useful life of cable.
4, the utility model is also provided with the liner core of polyether-ether-ketone material, oversheath hydrous water talcum layer, fire-retardant oxygen barrier layer etc., has excellent resistance to elevated temperatures.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
See accompanying drawing:
For the cable of certainly lowering the temperature of steel works equipment, comprise polyether-ether-ketone liner core 1, the center of polyether-ether-ketone liner core 1 is provided with thermometric core 2, three heat radiation cavitys 3 along annular space distribution are provided with in the polyether-ether-ketone liner core of thermometric core 2 periphery, the madial wall of heat radiation cavity 3 near polyether-ether-ketone liner core center is provided with protruding 4, be provided with power conductor 5 in protruding 4, power conductor 5 is outer is coated with high temperature resistance glass fiber band lapping layer 6 successively, polyether-ether-ketone insulating barrier 7 forms kinetic insulation core; Polyether-ether-ketone liner core 1 is outer is coated with neatly rock layers 8, fire-retardant oxygen barrier lining 9, polyether-ether-ketone external sheath layer 10 successively, polyether-ether-ketone external sheath layer is also provided with run through neatly rock layers 8, fire-retardant oxygen barrier lining 9, polyether-ether-ketone liner core 1 and with the cooling holes 11 of heat radiation cavity UNICOM.
Thermometric core 2 is connected with alarm by controller, can monitor in real time, reporting to the police, carrying out cooling operation rapidly when reaching core temperature normal working temperature.
