The utility model discloses a safe anti-explosion lightning arrester which comprises an insulating shell, an anti-explosion coil, a varistor and a top speed conduction coil. The varistor is arranged in the insulating shell, the top end of the varistor is fixedly connected with an energy-gathering metal ball through an upper conducting plate, an upper connecting piece and an electric conductive core body, a high voltage electrode is fixed to the middle position of the upper end of the energy-gathering metal ball, the bottom end of the varistor is connected with a ground conductive electrode through a lower conducting plate and a lower connecting piece, the top speed conduction coil is connected to the middle of the varistor and connected with the anti-explosion coil, and the bottom end of the anti-explosion coil is connected with the ground conductive electrode. The safe anti-explosion lightning arrester is simple in structure assembly, effective explosion prevention can be carried out through a protection circuit when the arrester is subjected to large voltage surge, and the safe anti-explosion lightning arrester is safe and reliable.
