Problems solved by technology

[0002] The current geothermal cable electric heating technology, its laying method is mainly wet laying method buried under cement, the structure of geothermal cable is mainly based on heating wire, single-layer insulation, single-layer shielding + ground wire, and the construction method is mainly In order to lay the heat insulation layer, steel wire mesh, geothermal cable, over-temperature protection temperature sensor, cement mortar + ground decoration layer, the laying and construction process is complicated, and due to the large construction site, there are few over-temperature protection temperature measurement sensors. , can not play the role of over-temperature protection, and because the geothermal cable and over-temperature protection temperature sensor are not well sealed during the construction process, the failure rate is high. Once damaged, it will be irreparable and there is no replacement. In order to solve these problems, some manufacturers have launched In the current dry laying method, the geothermal cable still uses the same products as the wet laying method, and the laying method is too simple, but the cement layer is canceled, and the ground decoration layer can only be the floor, which is limited. This type of dry laying method cannot be used in the living room, bathroom, kitchen and other places where tiles need to be installed in the family

Abstract

The invention relates to a dry type geothermal cable system with an intelligent over-current protection function, and belongs to the field of geothermal heating. The system comprises a heat insulationlayer paved on the ground, wherein the surface of the heat insulation layer is provided with grooves used for containing geothermal cables; a heat conduction layer is embedded into the grooves of theheat insulation layer, and the geothermal cables are laid in the grooves with the embedded heat-conducting layer, a current detection device is arranged in the grooves with the embedded heat-conducting layer, an aluminum plate is laid above the heat-conducting layer, and a grounding wire is connected to the aluminum plate, a decoration layer is laid on the aluminum plate, and the grounding wire and the geothermal cables are connected with a power supply; the current detection device is connected with a controller, and the controller is connected with the power switch, a preset temperature upper limit value is stored in the controller; the geothermal cable comprises a heating wire; and an insulating layer is wrapped outside the heating wire.

Description

Technical field [0001] The invention relates to the technical field of geothermal heating, in particular to a dry geothermal cable system with intelligent overcurrent protection. Background technique [0002] The current geothermal cable electric heating technology, its laying method is mainly based on the wet laying method buried under cement, the structure of the geothermal cable is mainly based on heating wire, single layer insulation, single layer shielding + ground wire, and the main construction method In order to lay the thermal insulation layer, steel wire mesh, geothermal cable, over-temperature protection temperature sensor, cement mortar + ground decoration layer, the laying and construction process is complicated, and due to the large area of ​​the construction site, the over-temperature protection temperature sensor is less distributed , Can not play the role of over-temperature protection, and because the geothermal cables and over-temperature protection temperature...
