COOLING SYSTEM FOR TRANSFORMER

摘要

PURPOSE: A cooling system of a transformer is provided to cool the transformer by circulating a cooling medium through a hollow of the transformer. CONSTITUTION: A cooling medium supply unit(100) supplies the cooling medium to a circulation transfer unit(200). The circulation transfer unit includes a first circulation pipe, a second circulation pipe, and a circulation pump. The first circulation pipe is connected to one end of the transformer winding. The second circulation pipe is connected to the other end of the transformer winding and the first circulation pipe. The circulation pump circulates the cooling medium through a hollow of the transformer winding. An insulation medium unit(600) is formed on both ends of the transformer winding. A cooling unit(300) cools the cooling medium circulated by the circulation transfer unit again.
