Micro-controlled electricity-saving protection device

The utility model discloses a micro-control electricity saving protection device, which comprises a power input end, a direct current feed circuit, a control circuit, an over-voltage detection circuit, a current leakage detection circuit, a load power detection circuit and a controllable switch circuit; wherein the controllable switch circuit is connected in a power feed circuit and receives the switch control signal output from the control circuit to further control the opening and closing of the power feed circuit; the input end of the control circuit receives the detection signal output from the over-voltage detection circuit, the current leakage detection circuit and the load power detection circuit to further determine the states of the switch control signals output from the output ends of the over-voltage detection circuit, the current leakage detection circuit and the load power detection circuit; the input end of the direct current feed circuit is connected with the power input end to ensure that the input voltage is converted into low voltage direct current to provide operational power supply for the control circuit, the over-voltage detection circuit, the current leakage detection circuit and the load power detection circuit. By adopting the micro-control electricity saving protection device, not only the equipment security can be enhanced, but also the power cut can be performed during the waiting of the electric appliances through power detection, to achieve the purposes of energy conservation and environmental protection.
