Withstand voltage test equipment

The invention provides a withstand voltage test device, relates to the technical field of series resonance withstand voltage tests, and is used for solving the technical problem that the test efficiency of the withstand voltage test device is low. The withstand voltage test device comprises a bottom plate, a variable-frequency power supply and an excitation transformer, and the variable-frequency power supply and the excitation transformer are both fixedly installed on the top surface of the bottom plate; the variable-frequency power supply is configured to be connected with an external power supply, the variable-frequency power supply is also electrically connected with the exciting transformer, and the exciting transformer is configured to boost the voltage output by the variable-frequency power supply so as to perform a withstand voltage test on the to-be-tested cable. The variable-frequency power supply and the exciting transformer are fixed on the same platform, so that the system is highly integrated, a
