The invention discloses a lightning prevention and ground potential high-voltage counterattack suppression protection circuit of a power line. The protection circuit comprises a TMOV module circuit and a lightning current frequency impeder, wherein the TMOV module circuit is connected in parallel to the power line, and the lightning current frequency impeder is connected in series to a ground wire. By the protection circuit, the technical problems that normal tripping cannot be achieved, power-frequency short circuit is caused and a fire is caused existing in a lightning prevention device in the prior art, and lightning surge voltage can be mutually conducted and interfered along a weak ground wire when flowing through lighting prevention ground and entering a combined ground network to cause ground potential high-voltage counterattack and high-voltage conduction existing in a grounding device are solved.
