Leakage Protection Circuit, Electrical Equipment, and Leakage Protection Method

Abstract

The present disclosure relates to a field of protection circuit technology, and discloses a leakage protection circuit, an electrical equipment, and a leakage protection method. The leakage protection circuit comprises: a leakage detection switch; a voltage detection unit, configured to detect an input voltage of a power supply to generate a voltage detection signal; a drive unit, configured to determine a type of input voltage of the power supply based on the voltage detection signal; a threshold generation unit, configured to generate a leakage protection threshold based on the type of the input voltage; a leakage protection unit, configured to detect an operation current flowing through the leakage detection switch and control a load to be in an off state if leakage is detected. The present disclosure not only expands the application scenarios, but also ensures the accuracy.
