Research on the Distribution Characteristics of Transformer Axial Vibration under Short-Circuit Conditions Considering Damping Parameters

The existing research on the distribution characteristics of displacement and acceleration transformer axial vibration under short-circuit conditions is based ignoring damping parameters. An accurate description windings, especially for winding conditions, has a poor effect. In this paper, damping, stiffness, mass parameters between windings are comprehensively considered, classical “mass-spring-damping” mathematical model established. After solving, natural frequency, main mode shape, displacement, each wire cake multi-degree-of-freedom (multi-DOF) system were quickly obtained. relationship deformation was discussed, axis summarized as well distribution.
