Timing leakage protection circuit and device containing same
A timing leakage protection circuit and a device containing the same. The timing leakage protection circuit includes a sensing unit, a switching unit, a ground fault circuit interrupter (GFCI) control unit, a switching control unit and an adjustable timing unit. The sensing unit and switching unit are used to be connected in series in a circuit to be protected. The switching control unit is configured to receive a control signal output by the GFCI control unit and control the switching unit to be open when receiving the control signal, so as to interrupt a circuit to be protected. Compared to the traditional leakage protection circuit, the circuit provided herein further has a timing function, so that the timing period can be controlled correspondingly according to different voltages, thereby reducing the circuit complexity and cost.

Disclosed herein is a leakage protector, which includes a housing. A base plate and a brush are arranged in the housing. A first conducting strip and a second conducting strip spaced apart are arranged on the base plate. The brush is provided with contact pins to contact the first conducting strip and the second conducting strip, respectively. The second conducting strip can generate different analog voltages, and the first conducting strip is configured to transmit different analog voltages to a microprocessor. A user can drive the brush to move through an actuating part, and set the power-on time of the leakage protector in one step.
