Abstract
A floor-heating cable multi-spot temperature monitoring device and a floor-heating cable with temperature sensors arranged in a spaced way both belong to the electric heating field and overcome defects existing in the conventional single-spot cable temperature monitoring means and characterized by small detecting range and safety hazard existence. The floor-heating cable multi-spot temperature monitoring device provided by the utility model is composed of digital temperature sensors arranged on multiple points along the floor-heating cable, a group of (three) temperature signal transmission lines shared by the temperature sensors, a temperature signal processing circuit connecting the temperature sensors and a temperature over-limit breaker controlled by the temperature signal processing circuit. The floor-heating cable provided by the utility model is formed by arranging the digital temperature sensors with a certain distance between adjacent two sensors and the temperature signal transmission lines connecting the sensors in a part between a shielding layer and an outer protecting layer of a conventional floor-heating cable, or between the shielding layer and an insulating layer or inside the outer protecting layer. The floor-heating cable multi-spot temperature monitoring device achieves multi-spot temperature monitoring along the whole line of the laid floor-heating cable, eliminates the monitoring blind area and prevents harm generated by the using of the cable in an over-limit temperature condition.
Description
Technical field
The invention belongs to electric-heating technology, be specifically related to the overheated monitoring of Geothermal electric cable.
Background technology
Along with the progress of technology and the people demand to the quality of making the life better, take imbed under the flooring heating cable as the geothermal heating mode of thermal source with its easily mat formation, controllability is strong, reduce expenses, be subjected to less the advantages such as other people restrict, be widely used gradually.For the Geothermal electric cable that prevents from imbedding the flooring overheatedly makes cable fault even causes disaster because of what the reasons such as overload or heat radiation be not smooth caused.Usually all at the other set temperature sensor of cable, and by temperature signal control cables power switch.The use-pattern of existing temperature sensor in electric underground heat mostly is the single position that cable will be drawn ground that is arranged on.This observing and controlling mode only reflects the cable temperature of a local location.To leaving other positions of cable leading out position, because having the not smooth coverture of heat conduction, ground makes this place's temperature over-range, form potential safety hazard.
Summary of the invention
The purpose of this invention is to provide a kind of Geothermal electric cable multipoint temperature monitoring device and by the Geothermal electric cable of setting the subsidiary temperature sensor of spacing, overcome the heating temp that the sensing range that existing single-point monitoring cable temperature exists is little, can not reflect whole section cable diverse location more comprehensively, have the shortcoming of potential safety hazard.
One group of (three) temperature signal transmission line that the Geothermal electric cable multipoint temperature monitoring device that the present invention provides is shared by the digital temperature sensor that arranges along the Geothermal electric cable multiple spot, temperature sensor, the processes temperature signal circuit that connects temperature sensor, and the temperature over-range isolating switch of processes temperature signal circuit control forms.
The Geothermal electric cable by setting the subsidiary digital temperature sensor of spacing that the present invention provides comprises heating wire, heat-resistant insulating layer, the wire netting outside the heat-resistant insulating layer or the foil shielding layer of parcel heating wire, the outer external protection of screen layer of existing Geothermal electric cable.The improvement of doing is in that spacing arranges digital temperature sensor and the temperature signal transmission line of one group of (three) connecting sensor of drawing along temperature sensor place interlayer by setting between screen layer and the external protection or between screen layer and the insulation course or in external protection.Make insulation processing between the contact of temperature sensor and temperature signal transmission line and the adjacent conductor.
Good effect of the present invention is: realized the Geothermal electric cable all fronts multipoint temperature monitoring to laying, eliminated the monitoring blind area, avoided cable to use the harm that brings under the temperature that transfinites.
