Accelerated thermal aging test device and method for insulating cushion block of oil-immersed transformer

The invention relates to the technical field of transformer testing, in particular to an oil-immersed transformer insulation cushion block accelerated thermal aging testing device and method.The oil-immersed transformer insulation cushion block accelerated thermal aging testing device comprises a bottom plate, a support, an L-shaped box, a driving assembly, a testing box, a supporting assembly and a pressure applying assembly; the insulation cushion block can be rapidly immersed in oil or taken out, meanwhile, a dry and suitable installation environment is provided for a traditional pressure sensor, the temperature testing range of a test is widened, meanwhile, an insulation cushion block supporting structure with the adjustable height is arranged, the aging environment of the insulation cushion block at different depths and different positions can be simulated, and the test efficiency is improved. Therefore, the test result is closer to the actual use condition, the accuracy of the test data is ensured, and
