Simulation Analysis and Benchmarking Validation of Magnetic, Electromagnetic and hybrid Shields in Large Power Transformers
(0) according to different theories the magnetic shunt, the electromagnetic shield and a combination of both in power transformer have protective shielding functions to mental components and decrease stray-field loss (including eddy current loss and hysteresis loss), avoiding damage to insulation devices caused by partial overheating for overconcentration of the loss.This paper will build a 2D modeling and simulation which proves the improved platform measuring the the shield loss and flux density of the transformer product model can provide a more reasonable flux complementary condition.Three kinds of shield in the model will be calculated by 3-D model simulation to research and compare the loss and flux density of the magnetic shunt, the electromagnetic barrier and the hybrid shield, which is of significant analyzable and referable value for optimizing the design of magnetic shields in large power transformers.
