Abstract: Insulators are important devices used to support electrical wires and electrical isolation in power systems, and are of great significance for online test of the insulation status of transmission and distribution lines. In this paper, in view of the shortcomings of manually discriminating aerial images at this stage, an insulator image fault detection scheme based on Faster R-CNN is proposed, and the principle of feature extraction for convolutional neural networks is described, and an insulator detection model based on Faster R-CNN is constructed. Utilizing aerial insulator images and fault samples of aerial drones, the detection model is trained and tested, and insulator classification detection experiments and insulator fault location experiments are performed respectively. Experimental results show that the proposed insulator fault detection method can accurately detect and classify insulators, locate the fault location, and meet the real-time requirements.
Key words: insulator detection; fault location; convolutional neural network; image detection; deep learning
