外鉄形変圧器タンクの流体-構造連成解析

抄録

Strong demand exists to reduce the noise in transformers for the sake of the environment. The noise of transformers can generally be reduced by increasing the size of the machines. However, this leads to increased costs, so a non-resonant design is needed for the transformer core, coil, and tank. This report, presents our investigation on the numerical analysis modeling method of the shell-type transformer tank. The results were that the numerical analysis model that modeled the tank and the oil flow channel could predict the natural frequency with an error of less than 12%.
