Title:
COOLING SYSTEM OF OIL-IMMERSED TRANSFORMER AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2009/105966
Kind Code:
A1
Abstract:
A cooling system of an oil-immersed transformer comprises several heat exchangers (2) and several condensing devices (3). The heat exchangers comprise oil-loop portions and evaporation cooling medium portions. The respective liquid medium in the oil-loop portions and the evaporation cooling medium portions doesn't contact and mix each other. The condensing devices are connected to the evaporation cooling medium portions of the heat exchangers. A cooling method of an oil-immersed transformer involves transmitting heat to a liquid evaporation cooling medium with lower temperature by oil of an oil-immersed transformer, where the cooling medium is a single evaporation cooling medium, or mixed medium of two or more than two kinds of evaporation cooling mediums. A gaseous evaporation cooling medium is condensed into the liquid evaporation cooling medium through a condensing tune and a condensing device. The liquid evaporation cooling medium is inversely passed to the heat exchanger.
