The present invention relates to an electric equipment state detection method and device, a computer device and a storage medium. The method comprises the steps of: obtaining historical oil temperature and a historical load rate of an electric device; inquiring an evaluation strategy table according to the historical oil temperature and the historical load rate to obtain a corresponding oil temperature-load state evaluation value, performing difference verification of the historical oil temperature and the historical load rate to obtain a difference level parameter, and performing clustering analysis of the historical load rate to obtain load rate classification data; and determining the state of the electric device according to the state evaluation value, the difference level parameter and the load rate classification data. The electric equipment state detection method and device, the computer device and the storage medium enrich the data sources of detection of the state of the electric device and improve the accuracy of the detection result so as to improve the objectivity of the evaluation of the device state.
