Abstract

The invention relates to an evaluation method for insulating material performance for a converter transformer. The evaluation method for the insulating material performance for the converter transformer comprises the steps that general physical property data and dielectric property data of insulating materials on the converter transformer are obtained; the general physical property data and the dielectric property data are processed, and then a corresponding standard deviation is calculated according to the processed data; a weight column vector is obtained according to the standard deviation;and a value of the general physical property, a value of the dielectric property and a comprehensive value are obtained according to the weight column vector. According to the evaluation method for the insulating material performance for the converter transformer, the achievement of the technical effect of optimizing insulating material performance comprehensive evaluation is facilitated.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a method for evaluating the performance of insulating materials used in converter transformers. Background technique [0002] As an important power transmission and transformation equipment, the converter transformer's operational reliability is directly related to the safe operation of the entire power system. At present, oil-paper insulation is the main insulation form of converter transformers. The characteristics of insulating paperboard directly or indirectly affect the reliability, safety and service life of related equipment. However, the working conditions of oil-paper insulation in converter transformers are very complicated and harsh. Power system Adjustment of frequency characteristics and voltage characteristics, switching of operating modes, and changes in the external environment (such as temperature and humidity) will all cause changes in the physical, chemical...
