The invention discloses an electric meter box for a smart power grid, relates to the technical field of electric meter boxes, and solves the problems that the maintenance is influenced by the disorder of wires during the hot-line work in the use process of the existing electric meter box, and the maintenance danger is easily caused by the exposure of the wires. An electric meter box for an intelligent power grid comprises a meter box mechanism, an electric meter installation mechanism is installed on the inner side of the meter box mechanism, and the electric meter installation mechanism comprises a protection supporting plate, a wire output base, a protection frame, a movable connecting strip, an elastic clamping strip, a limiting connecting stand column, a sliding plate and a separation installation frame. A wire output base is fixedly installed on the lower end face of the protective supporting plate, limiting connecting stand columns are fixedly installed at the four end corners of the upper end face of the protective supporting plate correspondingly, and a separation installation frame is fixedly installed on the inner sides of the four limiting connecting stand columns. According to the invention, the electricity meter is installed and protected in a hidden manner, so that the live-line maintenance operation of the electricity meter can be conveniently realized, and the use safety can be conveniently ensured by arranging and winding the wire.
