The invention relates to the technical field of flexible direct current power transmission, and discloses a lightning arrester configuration method and equipment for an extra-high voltage flexible straight valve, which can be used for respectively configuring a first lightning arrester and a second lightning arrester on an upper bridge arm and a lower bridge arm of a high-end valve group in the extra-high voltage flexible straight valve and configuring a third lightning arrester on an upper bridge arm of a low-end valve group in the extra-high voltage flexible straight valve. And a capacitive spherical lightning arrester is configured on the direct current bus between the high-end valve group and the low-end valve group. According to the invention, when related faults may cause overvoltage of the extra-high voltage flexible straight valve, the first lightning arrester, the second lightning arrester and the third lightning arrester configured on the extra-high voltage flexible straight valve and the capacitive
