750kV alternating current withstand voltage test equipment for high altitude

The invention discloses high altitude 750kV alternating current withstand voltage test equipment, which comprises a mounting frame, a test mechanism, a lifting mechanism and a driving mechanism, and is characterized in that the mounting frame is provided with a first surface and a second surface which are opposite to each other, and the first surface is used for being arranged on transportation equipment; the test mechanism is arranged on the second surface; the lifting mechanism is arranged on the mounting frame; the driving mechanism is arranged on the mounting frame and used for driving the lifting mechanism to ascend or descend. Compared with the prior art, the 750kV alternating current withstand voltage test equipment for the high altitude does not need to be transported by adopting a transformed truck carriage, so that the transformation cost is saved, the test cost is further reduced, meanwhile, the external insulation size of the equipment can be greatly increased, and the test efficiency is improved.
