The invention provides a substation equipment AR auxiliary maintenance method based on a three-dimensional knowledge graph and a terminal. The method comprises the following steps: acquiring a sound signal, a vibration signal and an infrared thermal image of a fault occurrence position; respectively carrying out feature vector extraction on the sound signal, the vibration signal and the infrared thermal image to obtain a fault feature vector; comparing the fault feature vector with a plurality of sample feature vectors in a fault three-dimensional knowledge graph to calculate similarity; determining a fault reason and a target maintenance scheme according to the similarity and the fault three-dimensional knowledge graph, and visually displaying the target maintenance scheme; and acquiring real-time image information of the fault site, generating a virtual-real combined image according to the real-time image information and the target maintenance scheme, and inputting the virtual-real combined image into a dis
