Ground fault circuit interrupter and detection method for the same

Abstract

Embodiments of the present disclosure relate to a ground fault circuit interrupter and a detection method for the same. The ground fault circuit interrupter comprises a ground fault circuit interruption switch, wherein when the ground fault circuit interrupter is connected to a power lines, the ground fault circuit interruption switch is coupled in series to the power lines, and the ground fault circuit interrupter comprises: a first drive circuit configured to drive the ground fault circuit interruption switch to open when being energized; a second drive circuit configured to drive the ground fault circuit interruption switch to close when being energized; and a controller configured to: in response to receiving a trigger signal for closing the ground fault circuit interruption switch, determine a state of the first drive circuit; and in response to determining that the first drive circuit is in a normal state, send to the second drive circuit a first connection signal to control the second drive circuit to switch on to close the ground fault circuit interruption switch; in response to determining that the first drive circuit is in an OFF state, not send the first connecting signal to the second drive circuit, thereby not energizing the second drive circuit. The solution according to embodiments of the present disclosure can eliminate safety hazards and ensure safety in electricity use.
