| Zusammenfassung: | The utility model relates to a ring main unit loop closing device, and especially relates to a ring main unit phase checking loop closing device. The ring main unit phase checking loop closing device is characterized in that an A grid transformer is individually connected with an A grid phase checking instrument and an A grid switching-on mechanism, a B grid transformer is individually connected with a B grid phase checking instrument and a B grid switching-on mechanism, and a C grid transformer is individually connected with a C grid phase checking instrument and a C grid switching-on mechanism. By utilization of the above technical scheme, the ring main unit phase checking loop closing device is safe and reliable, and economical and practical. |
