The invention relates to an intelligent suspending frame for the calibration of a three-phase electric energy meter in a laboratory, and belongs to the technical field of electric energy meter calibration. The suspending frame comprises a suspending rod, a lifting rod, a supporting frame, a suspending base, a base, a supporting rod, a wiring seat and a thimble. The suspending rod is fixed to the lifting rod. The insertion portion of the lifting rod is inserted into a sliding chute disposed on the supporting frame. The lifting rod can move up and down along the sliding chute. The wiring seat isfixed to the base through the supporting rod and is arranged below the suspending rod. The thimble is connected with a current line, a voltage line, and a signal line. The intelligent suspending frame replaces a traditional inefficient manual wiring mode, achieves smart wiring, and avoids erroneous and missed connection caused by the fatigue of wiring workers in large-scale calibration.
