Transformer performance evaluation method and system based on detection project data distribution rule

Abstract

The present invention provides a transformer performance evaluation method and system based on the detection item data distribution rule. Key evaluation parameter test items of the transformer are determined according to the representation content of the detection item data on the transformer performance. By analyzing the distribution rule of the detection data of the key evaluation parameter test items of the same type of transformers, the basic evaluation cardinal number of the key evaluation parameter test items is formed, and the targeted transformer performance evaluation judgment method is formed according to the deviation degree of the detection data of the detection items corresponding to the target transformer relative to the basic evaluation cardinal number. According to the method, the overall performance condition of the equipment of the target transformer under the current data background can be represented, and the basic conditions of key components, manufacturing processes or links and the like of the equipment can be effectively represented, so that necessary technical support can be provided for procurement management of network access equipment; and equipment manufacturers can discover performance defects or technical defects of the equipment and take measures in time to improve the product quality.

Description

technical field [0001] The invention belongs to the technical field of power equipment performance evaluation, and more specifically relates to a transformer performance evaluation method and system based on the distribution rule of detection item data. Background technique [0002] The distribution transformer is directly facing the user end. Although the voltage level is low, it has a large stock and has a more direct impact on the user. For this reason, grid access testing for distribution transformers is an important means to ensure product quality. [0003] Since the existing research results are mostly focused on the condition maintenance, condition evaluation and fault analysis of the equipment operation link, there are few related researches in the equipment access link. Although a large amount of detection data obtained before the operation of the equipment can effectively characterize the performance of the equipment, it lacks effective analysis and application. ...

Although a large amount of detection data obtained before the operation of the equipment can effectively characterize the performance of the equipment, it lacks effective analysis and application

It can neither provide the necessary technical support for the material procurement of equipment users, nor provide the necessary technical support for equipment suppliers to understand the technical shortcomings and performance defects of their own equipment
