Power supply system for carbon crystal floor heating system

Abstract

Disclosed is a power supply system for a carbon crystal floor heating system. The power supply system for the carbon crystal floor heating system comprises standard three-phase power and a control unit; the carbon crystal floor heating system is divided into three groups of carbon crystal plate units; all the groups of carbon crystal plate units comprise carbon crystal floor heating radiant panels with the same or approximate number and specifications; each carbon crystal floor heating radiant panel comprises a heat conduction layer and a carbon crystal plate which are vertically stacked; the heat conduction layers of the three groups of carbon crystal plate units are communicated and grounded; a power supply end of one group of carbon crystal plate unit is arranged between a null line and each phase power supply of the standard three-phase power in a connecting mode, and therefore induced leakage current of the carbon crystal floor heating system to the ground can be reduced. The control unit comprises a plurality of temperature sensors, three ways of control switches and a control center, wherein the control center real-timely monitors signals of the temperature sensors, compares the signals with a set value and sends control pulses with different frequencies or duty ratios to the control switches, and therefore temperature constancy of the carbon crystal floor heating radiant panels can be maintained. By means of the power supply system for the carbon crystal floor heating system, induced electricity acting on the carbon crystal floor heating system is mutually cancelled out, and the problem of induced electric leakage in livestock breeding is solved.

Description

technical field [0001] The invention belongs to the technical field of heating products, and relates to a power supply unit of a floor heating system based on carbon crystal materials. Background technique [0002] At present, carbon crystal floor heating has been widely used in family residences. The working principle of carbon crystal materials is that after nano-carbon crystals are electrified, under the action of an electric field, carbon crystal molecular groups produce a large amount of far-infrared rays with a wavelength of 8-15um. Far-infrared rays are like the radiant energy of the sun's rays, which are easily absorbed by the human body or objects, causing the body temperature to rise rapidly and realizing the conversion of electrical energy to heat energy. Tested by the National Far-infrared Testing Center, the intensity of far-infrared waves generated by the carbon crystal plate unit is over 30%. Therefore, 100% of the electrical energy input of the carbon crysta...

Problems solved by technology

[0003] When carbon crystal floor heating is used in poultry farms, when 220V single-phase AC power supply is used, the insulating layer and non-insulating layer materials surrounding the carbon crystal heating plate will make the carbon crystal heating plate surrounded by the humid environment of the farm. When the surface layer is connected to the ground, a large leakage current will be generated directly into the ground, especially when the number of carbon crystal plates used in the breeding farm is large, the air isolation at the front end of the power supply will be caused by excessive leakage current If the switch exceeds the leakage rating and trips frequently, and consumes a lot of energy; if the surface layer of the induced voltage is insulated from the ground, the leakage current will be connected to the ground through the body of the livestock when the body of the livestock touches the ground, causing the livestock to frequently Being shocked by induction, affecting the normal life of poultry and livestock
