Because the infrared electric heating metal wall surrounding plate wall heating system has the possibility of being in direct contact with a human body in application, the system must be provided with grounding protection and a leakage protector in a circuit from the safety point of view.
The electrothermal film as the heating core of infrared electrothermal metal wall boarding is a planar heating body, when the surface is covered with planar material (such as metal plate) with certain conductive property, the electrothermal film and the planar conductive material can form a capacitor structure. When the electrothermal film is electrified, an induced current (leakage current) is formed on the structural layer, and the size of the induced current is related to the area, the power supply voltage and the frequency of a product. The induced current will flow along the ground line to ground, but the leakage current is a non-fault current.
The leakage protector is used for the circuit to generate leakage fault due to insulation, and when the leakage current is more than 30 milliamperes, the leakage protection switch can act to cut off the power supply. However, the earth leakage protector does not have the capability of identifying non-fault and fault leakage, and the earth leakage protector can act to trip as long as the value of the leakage reaches a certain degree (30 milliamperes).
