WIND COOLING DEVICE OF DRY-TYPE TRANSFORMER AND DRY-TYPE TRANSFORMER

摘要

PROBLEM TO BE SOLVED: To provide a wind cooling device of dry-type transformer, capable of achieving cost reduction and high cooling performance without increasing a floor space of a dry-type transformer.;SOLUTION: A wind cooling device 16 cools a dry-type transformer 15 having a core 1 and a coil 2 wound around the core 1 with cooling air. The wind cooling device 16 includes: a flexible pipeline 4 which is disposed below the coil 2, surrounding the core 1 in a plan view and along at least a part of an outer periphery of the coil 2 and which is provided with a plurality of holes open toward the coil 2 and formed along the longitudinal direction; a cooling fan for supplying cooling wind to the pipeline 4.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
