A U-shaped iron core transporting/assembling tank is divided into a first leg iron core tank for housing a first leg iron core, a second leg iron core tank for housing a second leg iron core, and a lower-yoke iron core assembling tank. The first and second leg iron core tanks are integrated to constitute an erection tank. The lower-yoke iron core assembling tank has an opening portion for opening or closing which is formed in one longitudinal side surface of the lower-yoke iron core and through which the lower-yoke iron core can be carried in or out. The lower-yoke iron core assembling tank is connected at the opening portion which is opened when the lower-yoke iron core is housed in the lower-yoke iron core assembling tank.

U-shaped iron core transporting/assembling tank

Provided is a U-shaped iron core transfer/assembling method, by which a first leg iron core, a second-leg iron core and a lower-yoke iron core are housed in a first leg iron core tank, a second leg iron core tank and a lower-yoke iron core tank, respectively, and those iron cores are individually transported in sideways attitude. Next, the lower-yoke iron core is transferred into a lower-yoke iron core assembling tank. While the first leg iron core, the second leg iron core and the lower-yoke iron core being kept in the tilted postures, the first leg iron core tank, the second leg iron core tank and the lower-yoke iron core assembling tank are individually opened at their openings and are jointed to each other.

U-shaped iron core transporting/assembling method, and U-shaped iron core transporting/assembling tank

A stationary induction apparatus has: a winding to which AC current is supplied; an electrostatic shield which includes an electrostatic shield member having a hollow and an electrically conductive film wound around the electrostatic shield member, and which is configured to suppress the electric field of the winding; a housing which contains the winding, the electrostatic shield and the insulating fluid; an IC tag which has a sensor arranged in the hollow of the electrostatic shield member and configured to detect position of the electrostatic shield member, and a transmitter unit configured to transmit, by radio, information acquired by the sensor as a high-frequency signal having a frequency much higher than the frequency of the AC current; and a receiver unit which is arranged in the housing, receives the high-frequency signal transmitted by radio from the IC tag and transmits, by wire, the signal outside the housing.

Stationary induction apparatus and monitoring device thereof

A transformer transporting/assembling method comprises a transportation step of transporting a U-shaped iron core with an iron plate horizontally extending to a place near an installation site and an erection step of erecting the U-shaped iron core together with an erection tank from a state that the iron plate extends horizontally to a state that the iron plate extend vertically, with the U-shaped iron core contained in the erection tank. The erection step includes a sub-step in which a portal lifter composed of two booms which are vertically expandable and parallel movable with a predetermined distance therebetween and between which the erection tank is disposed and a beam horizontally connecting the two booms and vertically moved as the booms expands or contracts is used, the beam supports the erection tank through a flexible member at predetermined support portions, and the beam is vertically moved by expanding/contracting the booms.
