High sensitivity electric shock safety protection circuit

The utility model discloses a high sensitivity electric shock safety protection circuit, including relay J, rectifier bridge T, current transformer W and unidirectional thyristor Q1, relay J's contact J-1 is connected to current transformer W's winding N1's one end, relay J's contact J-1's other end connecting resistance R1, relay J and fuse FU, and the 220V alternating current is connected to fuse FU's the other end. The utility model discloses electric shock safety protection circuit adopts SF54123 type electric leakage safety protection dedicated chip as the master control original paper, in case the electric shock accidents appears on the power consumption main circuit, can extremely fast response, and break off the main circuit on the one hand, on the other hand sends the chimes of doom and reminds near the people in in time to take the rescue, therefore the circuit has reaction sensitivity, high, the manifold advantage of function of precision.
