Abstract

The invention provides an electrical equipment defect detection and maintenance method. The method includes the steps that a configuration file with a preset text format is generated according to attribute parameters, operating environment parameters and equipment state parameters of electrical equipment; text clustering processing including word segmentation, stop word screening, bag-of-words model establishment, feature word selection and feature vector model establishment is carried out on the configuration file, and automatic judgment and classification are carried out according to the similarity between defect information of the electrical equipment under the condition that how many defect types exist specifically is unknown beforehand; then, automatic matching is completed according to defect types having been known beforehand and corresponding keywords so as to obtain the defect type of the electrical equipment; accordingly, defect warning and maintenance can be carried out on the electrical equipment according to the defect type. By means of the method, the efficiency of defect detection and maintenance of the electrical equipment is improved, cost is reduced, and accuracy is improved as well.

Description

technical field [0001] The invention relates to the technical field of electric equipment maintenance, in particular to a defect detection and maintenance method for electric equipment. Background technique [0002] With the continuous development of the social economy, the power load has increased rapidly, and the number of substations has also increased year by year. Therefore, the operation quality of the primary power equipment in the substation needs to be paid more and more attention. Effective maintenance of substation power equipment and rapid repair of defects are important ways to improve the quality of substation operation. [0003] Detection and maintenance of power equipment defect status is an important part of power equipment management. The number of defects in power equipment directly reflects the health and maintenance quality of power equipment. How to effectively control the occurrence of defects in power equipment, minimize the occurrence of similar def...
