Problems solved by technology

This maintenance method cannot obtain real-time and accurate operation information of power equipment, and most of the obtained information is lagging behind. During the maintenance interval, the faulty operation status of the power system cannot be discovered in time, which increases the risk of system operation. , and even cause serious accidents
At the same time, the method of maintaining the power system according to rigid plans and regulations on the one hand brings unnecessary economic losses to enterprises and companies;

Abstract

The invention discloses a quantitative evaluation method and device for the health degree of a distribution transformer, equipment and a medium. The method comprises the steps of obtaining state indexdata of a distribution transformer; for the qualitative state index data, receiving score values input by operation and maintenance personnel; processing the quantitative state index data by adoptinga linear scoring method, and determining a score value of the quantitative state index data; calculating the subjective weight of each state index data in the overall situation of the defect tree; calculating objective weights of the state index data in the defect tree globally; calculating the comprehensive weight of each state index data according to the subjective weight and the objective weight of each state index data in the overall situation of the defect tree; and calculating a score value of the health degree of the distribution transformer according to the score value and the comprehensive weight of each state index data. According to the method, the health degree of the distribution transformer can be accurately evaluated, the inspection efficiency of the distribution transformer is improved for power enterprises, and a guarantee is provided for high-reliability operation of a power distribution network.

Description

technical field [0001] The invention relates to a distribution transformer health quantitative evaluation method, device, equipment and medium, and belongs to the field of differentiated operation and maintenance of electrical equipment in a medium-voltage distribution network. Background technique [0002] The distribution network has the characteristics of various types of equipment, a large number of equipment, a wide range of operating points, a complex network structure, and a poor security environment, which leads to a sharp increase in the inspection workload of the distribution network. [0003] Under the actual situation of limited operation and maintenance manpower and material resources, the inspection personnel have heavy tasks, which cause certain safety hazards. At present, for some important equipment such as distribution transformers, manual regular inspections are used, which fail to automatically identify the health and importance of each equipment to achie...
