Electric leakage detection device of electrical appliance

The invention discloses an electric leakage detection device of an electrical appliance, and belongs to the field of electric power detecting. The electric leakage detection device comprises a current sensor, a detection controller, an A/D conversion module and a central processing module. The current sensor is connected with the detection controller, the detection controller is connected with the A/D conversion module, and the A/D conversion module is connected with the central processing module. The central processing module comprises a single-chip microcomputer and further comprises a display unit, an alarm unit and a communication unit, all of which are connected with the single-chip microcomputer. After electric leakage occurs in the electrical appliance, electric leakage information can be remotely transmitted in time through the electric leakage detection device and be reported to a near-end worker through the display unit and the alarm unit, accordingly, electric leakage can be handled in time, and electric shock, fire disasters and other accidents can be prevented.
