Electric water heater with omnibearing electricity leakage protection function

The utility model relates to an electric water heater with an electric leakage and circuit breaking protection function. An electric leakage and circuit breaking protector of an electric water heater still comprises a zero sequence current transformer, a zero sequence current signal amplifying circuit, and a tripping relay. The utility model is characterized in that the tripping relay is a three-pole linking relay, and the contacts of three poles are respectively connected in series with an earthing wire of an electric water heater, and an incoming wire of the zero line and the live wire of a power source; at least one zero sequence current transformer is sheathed on a water inlet pipe or a water outlet pipe of the electric water heater; the zero line and the live wire simultaneously penetrate through the zero sequence current transformer; the working power sources of the tripping relay and the zero sequence signal amplifying circuit are connected to the zero line and the live wire on the outer side of the contact of the tripping relay. The utility model provides full electric leakage and circuit breaking protection, aiming at ubiquitous electric leakage and self electric leakage of electric appliances caused by incorrect connection of lines by people.
