The invention discloses a comprehensive test and analysis device for power transformer windings. The comprehensive test and analysis device comprises a direct-current resistance test module, a voltage ratio test module and a switching module which is used for switching the direct-current test module and the voltage ratio test module. Switching is performed through the switching module according to the corresponding test contents in power equipment tests, frequent changes of wiring in test by adopting two sets of fixtures is avoided, and efficiency in the power equipment tests can be obviously improved.
