Transformer withstand voltage testing device

The utility model relates to the technical field of transformer testing, in particular to a transformer withstand voltage testing device. The withstand voltage testing device comprises a testing unit,a plurality of conveying units arranged at intervals in the front-back direction and a control unit. A plurality of test stations are arranged on the test unit; the control unit is connected with themultiple conveying units and controls the conveying units to convey the to-be-tested transformers to the corresponding testing stations to be aligned with the corresponding testing stations for voltage withstanding testing or outputs the tested transformers, and the testing time of the transformers is accumulated. Wherein a plurality of transformers can be placed on the plurality of conveying units, the control unit controls the conveying units to run to a test station of the test unit to carry out voltage withstanding test, and the control unit can monitor the test time of the transformer oneach conveying unit; when
