Abstract
The utility model discloses a special fixed differential temperature detecting cable, belonging to the cable field, which comprises a PVC or PE outer sheath arranged as an outermost layer, the PVC or PE outer sheath is provided with a shielding layer, the shielding layer is provided with a bunch of cables, the bunch of cables is composed of and twisted with two reflow cables made by PTC, two core wire conductors coated by a NTC insulation layer, and two core wire conductors coated by a PVC insulation layer. The utility model is characterized in that the temperature rise in a detecting point can be obtained by the temperature difference compensation, a quick and sudden fire hazard and a slow temperature rise can be detected simultaneously and constantly in a large area. The utility model has the advantages of compound detection function, long detecting distant, repeated use, real-time monitoring function, multilevel alarm in different temperature grades, strong anti-mechanical damage ability and anti-electromagnetic interference ability.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of exploration cable.
Background technology
In the prior art, a kind of constant temperature exploration cable is arranged, mainly include two strands of heart yearns, cored wire conductor is surrounded by the NTC insulating barrier outward, and then is twisted into bunch of cables with two return wires, and screen is set outside bunch of cables, and screen is provided with the PVC oversheath outward.This cable can be used for the signal transmission, can be used as exploration cable and use, the outer NTC insulating barrier that is provided with of cored wire conductor is made by the NTC material, and the NTC material is a thermo-sensitive material, have following physical characteristics: promptly rising with temperature, its resistance is corresponding to be reduced, and descending with temperature, its resistance is corresponding to be increased; Therefore by detecting the insulation resistance between the outer NTC insulating barrier of optional position two cored wire conductors; promptly know the working temperature of this position cable; utilize temperature monitoring apparatus can show its working temperature; by obtaining the work temperature rise with the ambient temperature contrast; can set the warning temperature rise; or protectiveness is cut off cable work; when alarm temperature and ambient temperature differ bigger; this cable can reach good signal transmission and control; but; this constant temperature exploration cable can not be got rid of the influence of ambient temperature all the time in the acquisition of signal process; the ambient temperature that sets in the watch-dog; ambient temperature around the control appliance or a reference value given in advance often, rather than the actual temperature of cable service position detect temperature rise like this and will bring the problem that detects error.
The utility model content
The purpose of this utility model provides a kind of different constant temperature exploration cable, makes its temperature rise that can detect exploration cable more accurately, eliminates the error that ambient temperature causes.
The purpose of this utility model is achieved in that extraordinary different constant temperature exploration cable, comprise PVC or PE oversheath that outermost layer is provided with, be provided with screen in the PVC oversheath, be provided with bunch of cables in the screen, it is characterized in that: described bunch of cables comprises the return wire of two ptc materials, two cored wire conductor, two cored wire conductors that the PVC insulating barrier coats that the NTC insulating barrier coats, and the cored wire conductor that cored wire conductor that above-mentioned NTC insulating barrier coats and PVC insulating barrier coat and the return wire of ptc material are twisted into described bunch of cables.
During the utility model work, four cored wire conductors can carry out the signal transmission, can detect insulation resistance between the NTC insulating barrier and the insulation resistance between NTC insulating barrier and the PVC insulating barrier, two insulating resistance values are compared with computing can obtain the temperature rise of working more accurately, the temperature anomaly that the utility model can detect exploration cable optional position along the line changes, and can be used for fire alarm.But this product continuous large-area is surveyed fast burst fire and temperature rising at a slow speed simultaneously, has the complex probe function, its detection range is grown, can be reused, can monitor in real time, can also realize the multistage warning of different temperatures grade: adverse circumstances abilities such as its anti-mechanical damage, anti-electromagnetic interference are strong.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 PTC return wire, 2 screens, 3,6 cored wire conductors, 4 NTC insulating barriers, 5 oversheaths, 7 PVC insulating barriers.
Embodiment
As figure, be extraordinary different constant temperature exploration cable, comprise PVC or PE oversheath 5 that outermost layer is provided with, be provided with screen 2 in PVC or the PE oversheath 5, be provided with bunch of cables in the screen 2, cored wire conductor that described bunch of cables is coated by two PTC return wires 1, two NTC insulating barriers 43, two cored wire conductors 6 that PVC insulating barrier 7 coats are formed, and the cored wire conductor that above-mentioned NTC insulating barrier 4 coats and the cored wire conductor and the PTC return wire 1 of PVC insulating barrier 7 coatings are twisted into described bunch of cables.
But the situation that the extraordinary different constant temperature exploration cable of the utility model continuous monitoring ambient temperature along the line changes; Its pair cable structure can work in special rugged environments such as strong electromagnetic; The insulation resistance of sensing cable can recover behind overheated, the fire, and detector is reusable; A loop detector maximal use length 1000m, maximum pretective acreage 4000m
260 ℃～140 ℃ of alarm temperature setting ranges; Allow operating ambient temperature range-40 ℃～100 ℃; Can open a way and the short trouble warning; The static standby current of detector is less than 1mA; The State of alarm electric current is less than 10mA; Analog quantity standby current 4mA～20mA; Operating voltage 18V～26V; Work relative humidity 100%; The withstand voltage 10kV of senser.
