Abstract :
We have developed the gas-cooling system of a
275 kV, 300 MVA class gas-insulated transformer. In our study
model experiments in which gas flow was substituted by water
flow equivalently and 2-dimensional numerical flow analyses
and network analyses were conducted. In this paper the outline
of the development and optimization condition to get high cooling
performance in SF6 gas-disc winding system of the transformer
are presented.
