The installation area can be greatly reduced. At the same time, such assembling makes it possible to arrange not only the primary connection part and the secondary connection part of the main transformer but also the control cable and the like in the cubicle. Therefore, the pits that were required in the past are not needed, and the site of the power receiving and transforming equipment, the construction cost, and the construction period can be significantly reduced.

幅に削減することができる。Further, the gas-insulated switchgear, which is a power receiving switchgear, is filled with an insulating gas in the factory, which eliminates the need for on-site gas treatment. The power distribution switchgear can be transported even when the second to third surfaces are lined up. By doing so, it is possible to reduce the work of connecting the high-voltage side busbar and the control line after the installation in the field, and it is possible to significantly reduce the number of workers and the time after the installation.

By collectively arranging the power receiving switchgear, the transformer panel, and the power distribution switchgear with their non-maintenance surfaces in contact with each other, the maintenance / inspection space can be gathered and the installation area of the entire power receiving and transforming facility can be significantly reduced. it can. At the same time, such assembling makes it possible to arrange not only the primary connection part and the secondary connection part of the main transformer but also the control cable and the like in the cubicle. As a result, pits are not required, and the site of substation equipment, construction costs, and construction period can be significantly reduced.
