This invention provides a YOLO-based method for identifying fault types in 10kV distribution network lines, comprising: constructing a fault image dataset and data augmentation; constructing an improved YOLOv8 fault identification model architecture; constructing a multi-task loss function for fault identification; training the line fault identification model; inference detection based on line inspection images; post-processing optimization of fault detection results; and outputting identification results. This invention achieves high-precision, robust, and real-time intelligent identification and classification of various types of line faults in 10kV distribution networks, effectively improving the efficiency of intelligent inspections and the timeliness of fault early warnings, and ensuring the safe and stable operation of the distribution network.

The invention relates to a hydrogen storage alloy composite material and a preparation method thereof.The preparation method comprises the following steps that S1, hydrogen storage alloy powder, an organic solvent and a coating layer raw material are in contact and subjected to ball milling treatment, and a first product is obtained; the coating layer raw material comprises a first metal source and a first organic ligand, or the coating layer raw material comprises an MOF material; and S2, optionally, carrying out roasting carbon deposition treatment on the first product. According to the preparation method provided by the invention, the air poisoning resistance of the hydrogen storage alloy material can be improved.
