Automatic over-current protection geothermal cable system

Abstract

The invention relates to an automatic over-current protection geothermal cable system, belongs to the field of geothermal heating. The automatic over-current protection geothermal cable system comprises a ground thermal insulation layer (1) laid on the ground, and a vertical surface thermal insulation layer (2) laid at the front lower end of the periphery in the room, a an aluminum plating film (3) is laid on the ground thermal insulation layer (1), geothermal cables are fixed on the aluminum plating film (3), and a gap exists between the adjacent geothermal cables, a temperature detection device is arranged in the gap, and a steel wire mesh (5) is laid above the geothermal cables (5), and the steel wire mesh (5) is fixedly connected with the geothermal cables; the output end of a temperature detection device is connected with a comparison circuit, and the output end of the comparison circuit is connected with a power switch of the geothermal cables; the input end, except connecting with the temperature detection device, of the comparison circuit, is further connected with a preset temperature value, a cement layer (7) is laid on the steel wire mesh (5); and a decoration layer is laid on the cement layer (7).

Description

technical field [0001] The invention relates to the technical field of geothermal heating, in particular to a geothermal cable system with automatic overcurrent protection. Background technique [0002] As a winter heating method, geothermal cable electric heating is welcomed by the masses. In the current geothermal cable installation method, the wet geothermal cable installed in the cement is the main method. The current wet geothermal cable installation method is generally insulated. Thermal layer, aluminized film, steel wire mesh, geothermal cable, over-temperature protection temperature sensor, cement layer, and ground decoration layer. Generally, there is only one over-temperature protection temperature sensor in a room. This method of installation and laying cannot achieve good results. The heating effect is poor, the heat loss is large, the temperature rises slowly, and the over-temperature protection does not work, which makes some users dissatisfied with geothermal ...
