| Zusammenfassung: | The utility model discloses an anti influence electricity nuclear phase device of transmission line for check the phase sequence with transmission line, including A looks incoming end, B looks incoming end, C looks incoming end, ground terminal, ground connection change over switch, three voltage measurement device, three current measuring device, ground connection change over switch connects A looks incoming end, B looks incoming end, C looks incoming end and ground terminal, three voltage measurement device is provided between A looks incoming end and the ground terminal respectively, between B looks incoming end and the ground terminal, between C looks incoming end and the ground terminal, three current measuring device is provided between A looks incoming end and the ground connection change over switch, between B looks incoming end and the ground connection change over switch, between C looks incoming end and the ground connection change over switch. When checking the phase sequence, at first will coordinate the end to want a measuring looks ground connection, switch over ground connection change over switch again, whether correctly judge by the current value and the magnitude of voltage that record. |
