Modularized power supply test system and operation method

The invention provides a modularized power supply test system and an operation method, and belongs to the technical field of power supply detection, and the system comprises a test pedestal, a comprehensive test bench and an industrial control computer. By arranging a plurality of test bases comprising a plurality of test interface power supplies for fixing and connecting the power supply to be tested, corresponding tool clamps are configured according to pins of the power supply to be tested and are connected and fixed with peripheral equipment, if a piece to be tested needs to be replaced, only a power supply module on the tool needs to be replaced, the vast majority of repeated connection work is avoided, and the test efficiency is improved. The test efficiency is improved. The electrical parameter change conditions of a power supply to be tested in different load states are measured by arranging a comprehensive test board comprising an electronic load and a plurality of test instruments; and the test proc
