Abstract
The invention relates to a smart electric meter with an external transformer. The smart electric meter comprises a smart electric meter body which is provided with a three-phase current inductance input socket. An induced current output line is electrically plugged into the three-phase current inductance input socket. The other end of the induced current output line is connected with an external transformer. The external transformer includes a T-shaped base. The top end of the T-shaped base is provided with a ring body which is of a structure formed by splicing two semi-arcs, wherein the first splicing joint has an opening, and the other splicing joint is equipped with a locking clamp spring used to lock the opening at the first splicing point. The ring body is internally provided with an electromagnetic induction module of which the output end is connected with the induced current output line. According to the smart electric meter body, the transformer is arranged outside, and a load line can be mounted in by directly opening the gap of the transformer, without the need for penetrating. The safety is high. The electrical cabinet does not need to be powered off. Cost saving is achieved.
