Description
Technical field
The utility model relates to field of cable technology, particularly a kind of thermometric alarm cable.
Background technology
Fire is that the personnel that cause injure and one of disaster of property loss, and along with the fast development of China's economy, the extensive use of automatic technology, the increase of various electric installation, further increases the danger of breaking out of fire.In safety in production, also constantly occur news, some frequent accident still happens occasionally so far, and becoming of having is more and more outstanding, and the fire incident caused because of ignition of cable, power outage occupy significant proportion wherein.
According to electric power accident analysis, the fire incident caused due to cable fault accounts for suitable vast scale.Fire is once occur, and large area cable can be caused badly to ruin, and unit, by forced-stopping machine, causes great direct economic loss.Real time temperature detects and can give warning in advance, to take effective measures in time.According to large-scale power transformer, generator, circuit breaker, instrument transformer, electric capacitor temperature monitoring requirement that is inner or surperficial, bus, lay transducer at device interior or surface, realize temperature and monitor in real time.
Utility model content
For the needs of existing thermometric alarm cable development, the utility model provides a kind of thermometric alarm cable, adds the temperature measurement accuracy of cable, improves the temperature resistant grade of cable.
The technical solution of the utility model is achieved in that
A kind of thermometric alarm cable, comprise conductor, be disposed with insulating barrier and oversheath outside conductor, conductor is made up of the inner wire set gradually from inside to outside, semi-conductive layer and outer conductor, and semi-conductive layer is the NTC type ceramic band of wrapped sintering.
Wherein, preferably, also screen is provided with between described insulating barrier and described oversheath.
Wherein, preferably, described screen adopts silver-coated copper wire braiding to form.
Wherein, preferably, described inner wire and outer conductor are resistivity and the little copper alloy conductor of temperature coefficient of resistance.
Wherein, preferably, described insulating barrier is that the polytetrafluoroethylmaterial material of 250 DEG C is pushed and formed by adopting temperature resistant grade.
Wherein, preferably, described oversheath is adopt temperature resistant grade to be that the polytetrafluoroethylmaterial material of 250 DEG C pushes formation.
Wherein, preferably, described oversheath is formed for adopting the wrapped sintering of polytetrafluoroethylene band.
NTC type pottery, i.e. negative temperature coefficient (Negative Temperature Coefficient, NTC) ceramic material, is used widely in temperature survey, temperature control and temperature-compensating etc.
The beneficial effects of the utility model:
1. semi-conductive layer of the present utility model adopts wrapped sintering NTC type ceramic band, adds temperature measurement accuracy, improves whole cable temperature resistant grade.
2. oversheath of the present utility model adopts high-temperature resistant polytetrafluoroethylmelt material; Shielding adopts high temperature resistant silver-coated copper wire, improves whole cable temperature resistant grade.
