The invention discloses an alternating voltage test verification device for verifying an automatic single-phase kilowatt-hour meter production line. The alternating voltage test verification device comprises an insulating shell which is connected with the interior of the insulating shell through terminal blocks. The interior of the insulating shell comprises a resistive voltage division sampling circuit which is used for sampling high-voltage input signals, output signals of the resistive voltage division sampling circuit are transmitted to a measurement and detection unit for measuring the sampled voltage, the measurement and detection unit is communicated with an MCU unit through an SPI (serial peripheral interface), and a measurement value is displayed on a display module controlled by the MCU unit; a power source and a management unit thereof supply power to the MCU unit and the measurement and detection unit. The alternating voltage test verification device is simple, direct, portable and convenient for operators to connect wires, test and read data, and voltage withstanding test efficiency can be improved greatly.
