specific Embodiment

[0093] Oil-immersed transformers are composed of iron core, winding, insulation, casing and necessary fixing parts. Large-scale transformers often have oil passages between turns and layers of windings, so that transformer oil can circulate in the box to improve heat dissipation efficiency.

[0094] As a device that realizes energy transfer and voltage conversion, all application functions of the transformer come from the transformer itself. Based on a certain mechanical structure, it realizes the conversion of electric and magnetic energy, and uses oil as a medium to assist insulation and heat dissipation to ensure electromagnetic energy. implementation of the conversion. Therefore, the ontology of the knowledge graph can be established according to the physical structure and physical characteristics of the transformer. Corresponding to the actual equipment in the physical world, the interrelated relationship of the knowledge ontology also corresponds to the physical relation...

Abstract

The invention discloses an ontology design method of a power equipment knowledge graph, belongs to the technical field of power system intelligent power transformation, and aims to analyze and hierarchically classify power equipment knowledge according to the physical structure and function of power equipment so as to construct the power equipment knowledge ontology. Power equipment knowledge ontology is divided into physical equipment group components, physical characteristic quantities, physical phenomena, equipment application ontology and the like, equipment is described by utilizing structural attributes and functional attributes of the equipment, multi-source and multi-structure knowledge is expressed by using unified layered and classified knowledge ontology, and a direct relationship between the knowledge and physical equipment is established. The knowledge ontology is preliminarily formed, knowledge embedding and completion are carried out on the framework, and power equipmentknowledge is expanded and enriched.

Description

technical field [0001] The invention belongs to the technical field of electric power system intelligent transformation, and in particular relates to an ontology design method of a power equipment knowledge map. Background technique [0002] Power equipment includes relevant standards and specifications, product design, inspection and testing, operation and maintenance management, and troubleshooting records, etc., accumulating a large amount of data and record text. How to realize the computer representation of these knowledge for fast query, intelligent search and knowledge reasoning is of great value for standardizing the arrangement of digital knowledge of power equipment, the application of theoretical and empirical knowledge, and improving the level of equipment operation and maintenance, maintenance and training. [0003] Most of the established power equipment knowledge bases are a combination of multi-source and different structural knowledge, which are usually desc...
