| 摘要 |
The present invention relates to a grounding device for high voltage instruments, particularly for earthing switches and earthing switches disposed on a power plant disconnecting switch, consisting of a frame (1) with a drive shaft (9) bearing (3) located at the point of a central insulator (2) on the frame (1), wherein the drive shaft (9) is connected at its one end with a drive (10). Two “V” or “U” shaped grounding bars (4), being located on the drive shaft (9) are connected above with each other by a first electrically conducting cross bar (5) with electrically conducting contacts (8) that are fixedly attached at the point of insulators (2), whereby on the ground potential, both the grounding bars (4) are connected with each other by means of a second electrically conducting cross bar (11) and joined with the frame by an elastic electrically conducting coupling (6). |
