TRANSFORMER SYSTEM TO BE SET ON THE ROAD

摘要

PROBLEM TO BE SOLVED: To respond to further capacity increase of a transformer while maintaining the size of an outer casing of a transformer system to be set on the road.;SOLUTION: A transformer tank 3 accomodating the transformer 1 is disposed in the outer casing 2. The casing 2 is provided with ventilation holes 6b and 7 for releasing heat from the transformer 1. When the capacity of the transformer 1 is increased with the size of the outer casing 2 maintained, the heat radiation area of the transformer tank 3 is reduced in so far as the surface temperature of a ceiling board 6 of the outer casing 2 and the temperature of discharge air from the ventilation hole 6b provided in the ceiling board 6 of the outer casing 2 do not exceed predetermined values.;COPYRIGHT: (C)2006,JPO&NCIPI
