PURPOSE:To enable a uniform dispersion of the coolant by a few number of dispersion means by a method wherein a dispersion means is rotated under a utilization of the coolant injection force. CONSTITUTION:Pipe 8 is provided with a dispersion means 11 having such a structure as a leading end of the nozzle is rotated under a utilization of reaction force of coolant flow in such a way as found in the sprinkler. Since the injection port of the dispersion means 11 the rotated, the coolant 5 is relatively uniformly dispersed over a wide area. Thereby, the transformer main body 3 stored in the sealed container 11 with electric insulation gas 2 is cooled by an evaporation heat generated when the dispersed coolant 5 is evaporated. |
