Provided is an anti-shunt-running circuit of a mechatronic electric energy meter. The circuit comprises a resistor, a polypropylene capacitor, leads and current sampling amplifiers. The resistor is connected in series in a metering loop, the polypropylene capacitor is connected in parallel with the resistor, and the output ends of the two current leads are respectively connected with the current sampling amplifiers. The resistance of the resistor is less than or equivalent to 50ohm, and the capacitance of the polypropylene capacitor in parallel connection with the resistor is greater than or equivalent to 10microfarad. The anti-shunt-running circuit of the mechatronic electric energy meter has the advantages that connection of the resistor in the resistance of 50ohm does not influence the metering accuracy and stability; in common states, the resistor is connected with the capacitor in parallel, and the current sampling currents has relatively high resistance to common-mode interference, so that the potentials at the two ends of the current sampling circuits are consistent, and shunt running does not occur in the electric energy meter; even if the shunt running phenomenon occurs, the current sampling amplifiers output signals, and the electric energy meter is automatically reset after receiving the signals; and thus, faults of the electric energy meter are effectively reduced, and the operational reliability of equipment is improved.
