INSULATION OIL COOLING TYPE DRY TRANSFORMER WITHOUT USING SPACER IN WINDING OF PRIMARY AND SECONDARY COILS

摘要

PURPOSE: An insulation oil cooling type dry transformer is provided to reduce the size and weight of the transformer by eliminating the necessity of forming a spacer in winding of primary and secondary coils. CONSTITUTION: An insulation oil cooling type dry transformer(1) is characterized in that the transformer is filled with an insulation oil so as to maximize insulation and cooling efficiency of primary and second coils. The transformer includes an insulation oil tank(6) arranged on the top of the transformer; and an insulation oil pipe(7) for connecting the insulation oil tank and the transformer such that the insulation oil of the insulation oil tank circulates through the transformer by a convection phenomenon. The insulation oil tank is supported by a bracket(10) arranged on the top of the transformer.
