Low-power-consumption overheating self-processing relay

The invention relates to the technical field of automation and control, in particular to a low-power-consumption overheating self-processing relay which comprises a machine body, a gravity balance mechanism is arranged on the upper portion of the machine body, and a magnetic suction scraper mechanism is arranged on the upper portion of the machine body. Meanwhile, according to the ohm law, in the same circuit, the current passing through a certain section of conductor is in direct proportion to the voltage at the two ends of the section of conductor and is in inverse proportion to the resistance of the section of conductor, that is, according to the ohm law, the input end is stable, that is, the voltage and the current are stably input, and due to the fact that the resistance is increased due to high temperature of the coil, the current is reduced; in the prior art, the voltage is too high due to the fact that overvoltage protection is not provided in the relay, components are burnt out and damaged, it can be
