To provide a power receiving and transforming device for protecting various equipment inside the device body from being exposed to water when an area therearound is flooded.
In the power receiving and transforming device for transforming electricity transmitted from an electric power station via a substation, an air-sealing protection member 2 is provided covering a whole cubicle 1. The internal volume of the protection member 2 is determined to limit a water exposure level inside the protection member 2 when flooded at a predicted water level H, within an allowable value h, by means of a balance between the compressive force of water 12 entering from the lower part of the protection member 2 on sealed air 13 inside the protection member 2 and the repulsive force of the compressed air.
