The utility model relates to a high-voltage fusing type direct-current lightning arrester, which comprises a single-column fusing type direct-current lightning arrester, the single-column fusing typedirect-current lightning arrester comprises a zinc oxide valve plate unit and a fuse which are connected in series, and the zinc oxide valve plate unit and the fuse are encapsulated by an epoxy cylinder to form the single-column fusing type direct-current lightning arrester. A plurality of single-column fusing type direct-current arresters are connected in parallel and then packaged to form a single arrester, and a plurality of single arresters are connected in parallel into a group to form an arrester group. According to the fusing type direct current lightning arrester group, a multi-columnand multi-branch parallel operation scheme is adopted; the fuse of the faulted column can be automatically fused before the characteristic failure breakdown of the single-column fusing type direct-current lightning arrester and the structure are not damaged; When the single-column fusing type direct-current lightning arrester breaks down and breaks down, the single-column fusing type direct-current lightning arrester automatically fuses and is isolated from the whole lightning arrester set, the remaining direct-current lightning arrester sets can continue to operate, it is guaranteed that thedirect-current system is not locked, and the reliability of the direct-current power transmission system is improved.
