The utility model relates to a multifunctional verification device integrated with a mutual inductance access type three-phase meter and a concentrator. Two sides of a workbench are transversely provided with multiple mutual inductor access type acquisition units in a spacing way. The multiple mutual inductor access type acquisition units are identical in structure and respectively provided with multiple connecting columns used for acquisition. The middle part of the workbench is provided with a lifting supporting plate in a guiding way. The two sides of the upper end of the lifting supporting plate are transversely and evenly provided with multiple detection modules in the spacing way. The detection modules of the two sides are corresponding to the mutual inductor access type acquisition units on the workbench in a one-to-one way. A main frame below a power supply cabinet is internally provided with a master control cabinet in a fixing way. The position, which is arranged on one side of the master control cabinet, in the main frame is fixedly provided with a switching device. An existing three-phase meter automatic verification wire can be modified, a device enabling an electric information acquisition terminal to be automatically connected is installed, and connection with a detection circuit is realized via coordination with the switching device so that various production detection requirements can be flexibly met by an assembly line and efficiency can be effectively enhanced.
