Abstract

The invention discloses a distribution transformer health assessment method, and the method comprises the steps: building a distribution transformer health assessment index hierarchical structure model according to an assessment index of a distribution transformer; Calculating subjective weights and objective weights of the evaluation indexes; Calculating a comprehensive weight according to the subjective weight and the objective weight; Calculating the weighted sum of the evaluation indexes according to the comprehensive weight to obtain a comprehensive score of the health state of the distribution transformer; And sorting the distribution transformers according to the comprehensive scores of the health states of the distribution transformers. According to the distribution transformer health assessment method, the problem that the assessment result is easily distorted because the weight setting is too subjective only depending on an analytic hierarchy process is avoided; Through calculating the subjective weight and the objective weight, more accurate distribution transformer health assessment is realized, maintenance personnel are helped to comprehensively and timely master the health condition of the distribution transformer, so that enterprises can timely arrange the maintenance work of the distribution transformer, and the distribution transformer faults are reduced.

Description

technical field [0001] The present application relates to the technical field of distribution network operation and maintenance, in particular to a distribution transformer health assessment method. Background technique [0002] Distribution transformer, referred to as distribution transformer, refers to a static electrical device in power distribution system that transforms AC voltage and current according to the law of electromagnetic induction and transmits AC energy. Distribution transformers directly face end users, and their health and operating conditions are directly related to the safety and reliability of power supply. Distribution transformers are important assets of power grid companies. At present, major power grid companies attach great importance to distribution transformer health inspections, mainly relying on system monitoring combined with manual regular inspections to complete distribution transformer faults or abnormal repairs. [0003] At present, the A...
