Intelligent leakage protector with special wave protection function

The utility model discloses an intelligent electric leakage protector with a special wave protection function. A power supply line accessed to a user passes through the zero-sequence current transformer. A rear primary winding is wound on the zero-sequence current transformer; wherein the secondary winding is wound on the permanent magnet switch, the permanent magnet switch drives the release to act to control the on-off of a power supply circuit connected to a user, the power supply circuit connected to the user is a three-phase alternating current, and one phase of circuit is grounded or connected with a zero line after being connected with a resistor with the resistance value of 1k-2k ohms in series. The utility model provides a low-voltage transformer area leakage protector with a special wave protection function. A contact current special waveform formed by human body electric shock is detected; compared with leakage current waveforms formed by other media and the ground, a special waveform is defined, a
