Zusammenfassung: | The utility model discloses a three-phase direct-type tool for replacing an electric energy meter without power cut, and relates to the field of electric energy meter replacement tools. Most of the conventional electric energy meter replacing tools without power cut adopt a relatively simple mechanical structure and a simple circuit, are relatively complicated in use and operation, are insufficient in intelligence and safety guarantee, and also adopt relatively complicated circuits, but are relatively complicated in structure and inconvenient to operate and maintain. The device comprises a control box and a connecting wire, an alternating current contactor and a control panel are arranged in the control box, and on-off indicating lamps of A, B, C and N phases and a self-locking switch are arranged on the front side of the control box. The electric energy meter can be replaced by a user without power failure, the intelligent operation reminding function is high, the overall operation is convenient, the meter r |
