The invention discloses a transformer oil filtering device for a high-altitude area and a filtering method thereof, and particularly relates to the field of transformer oil filtering, the transformer oil filtering device for the high-altitude area comprises an oil filter, the input end of the oil filter is connected with an oil outlet main pipeline, and the output end of the oil filter is connected with an oil inlet main pipeline; the oil tanks to be filtered are arranged in multiple groups and are respectively communicated with the oil outlet main pipeline; the plurality of groups of empty oil tanks are respectively communicated with the oil inlet main pipeline; and the oil injection pipeline is communicated with the oil inlet main pipeline, and a switching valve is installed at the joint of the oil injection pipeline and the oil inlet main pipeline. During oil filtering operation, oil inlet and outlet pipelines do not need to be disassembled for oil tank switching, the oil paths are switched through the cor
