The method comprises the steps of calculating a current peak value when an electric appliance inserted into a socket fails, calculating a fault current threshold value of the electric appliance inserted into the socket according to the current peak value, determining that the electric appliance inserted into the socket is a fault device when the working current is larger than the fault current threshold value, disconnecting the electric connection between the socket and the electric appliance, and accurately judging whether the electric appliance fails or not and whether a short circuit exists in an internal circuit of the electric appliance through calculating the fault current threshold value of the electric appliance, so that the phenomenon that the electric appliance is damaged or even a fire disaster is caused finally due to the fact that the circuit or an electronic device is burnt out due to the short circuit of the fault electric appliance is effectively avoided, and the phenomenon that the power is increased suddenly due to the fault of the individual electric appliance, so that the use of other equipment is influenced is prevented.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
