Computation and Analysis of Static and Dynamic Radial Stability of Power Transformer Inner Winding

Article Preview

Abstract:

In this paper, the size of winding electromagnetic force after short circuit has been acquired through leakage field calculation and analysis on power transformer, and based on the computation results, the radial stability experimental results of large capacity power transformer inner winding short-circuit model were compared to the simulation values to guide actual product analysis and checking. With the accumulated simulation experience on this model, then a type of sfz9-80MVA power transformer inner coil static and dynamic stability has been checked to confirm the radial instability phenomenon could whether or not occur on this product.
