In order to accurately find the heating defect factors of GIS substation equipment,make reasonable maintenance plan,this paper designs a GIS substation equipment heating defect factors identification system under vibration feature estimation.The data layer is used to collect and store the relevant data of GIS substation equipment,and the data of the data layer are transmitted to the application layer through the component layer.According to the received data,the vibration features are esti-mated in real time to judge whether the equipment has heating fault.The infrared image data of the equipment is extracted in the data layer to determine the heating area,and the relative temperature difference discrimination method is used to measure the temperature data of the heating area,The percentage of relative temperature difference is calculated.According to the set temperature threshold,the heating defect factors are identified and transmitted to the display layer.The experimental results show that the system can accurately locate the heating area and identify the heating defect factors in judging whether there is heating fault in GIS substation equipment.For a small heating area,the system can still locate accurately,and has better recog-nition effect of heating defect factors.
