The invention relates to a multi-station alternating-current voltage testing device, and belongs to the technical field of electric energy measurement. According to the multi-station alternating-current voltage testing device, a movable trolley is adopted, the movable trolley comprises a high-voltage source, a display detection unit and testing trays, the testing trays are at least two in number and are arranged on different supporting layers of the movable trolley, each testing tray is provided with at least two testing stations, each testing station is provided with a testing clamp corresponding to a product to be tested, the high-voltage source is in parallel connection with power supply terminals of the testing stations, the display detection unit comprises display modules corresponding to the testing stations respectively, and each display detection module is used for displaying an insulation leakage current parameter value measured on the corresponding testing station. By means of the testing device, multiple electric energy measurement products can be tested at the same time, each product is independently displayed and warns, and the problems that a voltage-resistant testing instrument can only detect one electronic product at a time and manual wiring achieved by workers is complex are solved.
