Temperature-based power transformation cabinet fault detection method and system

The embodiment of the invention mainly relates to the technical field of power transformation cabinet fault detection, in particular to a temperature-based power transformation cabinet fault detection method and system. The invention discloses a temperature-based power transformation cabinet fault detection method. The method comprises the following steps: S1, obtaining an environment temperature in a power transformation cabinet to obtain a first temperature value; s2, inputting the first temperature value and the part model of the fault to-be-judged part into a first temperature prediction model to obtain a second temperature value; the first temperature prediction model is trained through first data, the first data comprises a first temperature value, a part model and a second temperature value, the first temperature value is the environment temperature in the power transformation cabinet, and the second temperature value is the part temperature detected when the environment temperature in the power transf
