Transformer operation risk assessment method and device, electronic equipment and storage medium

The invention discloses a transformer operation risk assessment method and device, electronic equipment and a storage medium, which are used for solving the problem that in the prior art, the research on the operation risk of a residence transformer is relatively limited, differential operation between transformer clusters and environment working conditions are not considered, and the risk assessment result is easy to break away from the reality. The method comprises the following steps: firstly, acquiring a top oil temperature and a winding hot-spot temperature of a to-be-evaluated transformer, and calculating a first overload risk value based on the top oil temperature and the winding hot-spot temperature; calculating an aging acceleration factor of the to-be-evaluated transformer in combination with the winding hot-spot temperature, and calculating a second overload risk value according to the aging acceleration factor; acquiring outdoor meteorological data, and calculating a random failure risk value of t
