The directional explosion-proof lightning arrester comprises a top shell, an equipment connecting end, an insulating core body, a shell I, a base, a shell II, a valve plate, a lower electrode and a spring piece II, and the bottom of the shell I is fixedly connected with a directional pressure relief device. By arranging the directional pressure relief device, the inner wall of the fixed cylinder is smooth and free of stress concentration points, the wall thickness of the pressure relief shell is smaller than that of the fixed cylinder, and when the lightning arrester breaks down, high-temperature and high-pressure gas is released through the pressure relief shell, so that the effect of directional pressure release of the lightning arrester is achieved, and personal injury accidents caused by comminuted explosion of the lightning arrester are avoided; the conical spring can enable the lantern ring and the elastic sealing ring to be attached to the connecting pipe more firmly, the sealing performance of the con
