Leakage protection circuit, circuit board and electrical equipment

The utility model discloses an electric leakage protection circuit, a circuit board and electrical equipment. The electric leakage protection circuit comprises an AC power supply, a rectification branch, a relay branch, an indication branch, an electric leakage acquisition branch and a load electrical appliance. When the relay branch is in the first working state, the rectification branch is turned off, and the AC power supply is connected with the load electric appliance. The electric leakage acquisition branch is connected with a shell of a load electric appliance to detect electric leakage current; the electric leakage acquisition branch is connected with the relay branch and supplies power to the relay branch through the electric leakage current so as to enable the relay branch to act; when the relay branch is in the second working state, the load electric appliance is turned off, the alternating current power supply is connected with the input end of the rectification branch, and the output end of the re
