Oil paper insulation aging stage identification system and method based on deep residual network

The invention provides an oil paper insulation aging stage identification system based on a deep residual network, and the system comprises a partial discharge detection device which is used for obtaining oil paper insulation partial discharge pulse phase distribution maps at different thermal aging stages; the detection data sample expansion unit is used for expanding a data sample based on the oil-paper insulation partial discharge pulse phase distribution map; the graying processing unit is used for graying the oil paper insulation partial discharge pulse phase distribution map after the data samples are expanded; and the deep residual network unit comprises a preprocessing module, m residual modules connected in series and a full connection layer module which are connected in sequence, and the deep residual network unit is used for classifying and identifying the oil paper insulation aging stage according to the grayed oil paper insulation partial discharge pulse phase distribution map. The system can eff
