Leakage current detection and interruption device for power cord and related electrical connectors and electrical appliances

A leakage current detection and interruption device, comprising:

• a switch module, including a reset switch, coupled to power supply lines between an input end and an output end and configured to control an electrical connection between the input end and the output end;
• a leakage current detection module, including at least one leakage current detection ring and a signal processing circuit coupled to the at least one leakage current detection ring, configured to detect a leakage current on the power supply lines and to generate a leakage fault signal in response thereto;
• a drive module, including a drive coil and a drive circuit coupled in series to the drive coil, coupled to the leakage current detection module and the switch module, and configured to control the switch module to disconnect or connect the electrical connection between the input end and output end;
• a wireless communication module, including a signal processing chip and a photocoupler, wherein the signal processing chip is coupled to the output end of the power supply lines via the photocoupler, and configured to detect a power loss at the output end, wherein the wireless communication module is further configured to wirelessly transmit information regarding the power loss to a remote control device;
• and
• at least one power supply circuit, configured to supply a power to the leakage current detection module and the wireless communication module.
