Summary:The utility model relates to a combined grounding device for a hydropower station. The station mainly comprises a cross-river underwater grounding grid and a shore land grounding grid. The cross-river underwater grounding grid comprises cross-river longitudinal strand cables (1) and cross-river transverse strand cables (2). One end of each cross-river longitudinal strand cable (1) is connected with a dam grounding grid through a fixing point (7). Two ends of each cross-river transverse strand cable (2) are connected with the shore land grounding grid. The shore land grounding grid mainly comprises shore longitudinal strand cables (9) and shore transverse strand cables (8) that are fixedly disposed on the shore cliffs or in the mud. Electrolytic earth polar (10) is buried in the periphery of the shore land grounding grid. The electrolytic earth polar (10) is connected with the shore transverse strand cables (8) through hot melt soldering points (3). The device meets the requirements of the ground screen impose
