The invention relates to the technical field of power grid operation monitoring, in particular to automatic inspection equipment for power grid operation. The equipment comprises a visible light shooting module, an infrared imaging shooting module, an ultraviolet imaging shooting module, a graying processing module, an infrared visible light fusion device, an ultraviolet visible light fusion device and a fusion result processing device. The visible light, ultraviolet light and infrared light three-in-one fusion automatic inspection function can be realized, carrying of monitoring equipment isreduced, one-by-one disassembly and assembly are not needed, and time and labor are saved. A judgment result is output, the position of a heating point is accurately obtained, and fault misinformationis avoided. A heating point training sample is compared with an infrared visible light image through a convolutional neural network to improve the accuracy of finding the heating point, a discharge phenomenon training sample is compared with a discharge phenomenon visible light image through the convolutional neural network to improve the accuracy of finding a discharge phenomenon without manually observing the image for judgment, automatic and accurate cruise diagnosis is achieved, and the risk of manual judgment errors is avoided.
