Abstract

Using the leakage current of transmission line insulator can effectively characterize the external insulation state of insulator, which plays an important guiding role in flashover prevention and control. However, the actual situation is complex. How to correspond the monitoring data and various maintenance information with the leakage current has become a problem to be solved. Knowledge graph can present the knowledge structure relationship between different entities in a visual way, and can achieve the purpose of efficient data storage and accurate retrieval. Based on the knowledge graph, this paper will obtain the influencing factors of leakage current by analyzing the existing data and using knowledge extraction, and Neo4j is used to build the relationship between nodes, edges and attributes, and then complete the construction of knowledge graph. This is of great significance to improve the accuracy of leakage current prediction and use the predicted value to guide flashover prevention and control.
