Analysis of Radial Deformation Degree of Power Transformer Windings Based on Maximum Deformation
摘要
Abstract
Aiming at the challenges of accurately quantifying the radial deformation degree of power transformer winding by winding frequency response characteristic analysis method and low voltage short circuit reactance method,a quantitative analysis method for the radial deformation degree of winding is proposed.This method uses the change rate of short-circuit reactance relative to the normal state when the winding generates the maximum radial forced buckling deformation to represent the degree of winding deformation.Case analysis shows that the proposed method is suitable for concentric winding,which can make up for the shortcomings of the current judgment method,and can accurately judge the radial deformation degree of winding,especially for large capacity and high impedance transformer,where the advantage is more obvious.关键词
