Gas-isolated heavy current transformer uses 2-stage heat exchanger with circulated heat transfer medium used for removing heat from isolation gas enclosing transformer

摘要

The transformer has a circulated heat exchange liquid, e.g. water, used for removing heat from the isolation gas enclosing the transformer via a 2-stage heat exchanger, the isolation gas provided by sulfur hexafluoride at a pressure of between 1 and 5 bar.
