Abstract

A power receiving and transforming system comprising a gas insulated switchgear, with transformers being disposed adjacent the gas insulated switchgear and metal enclosed switchgear sections disposed on opposite sides of the transformers with respect to the gas insulated switchgear. The metal enclosed switchgear sections have metal enclosed switchgear units juxtaposed in a direction in which the gas insulated switchgear and the transformers are juxtaposed. The metal enclosed sections are located opposite to each other in a direction perpendicular to the direction of the juxtaposition. Therefore, the metal enclosed switchgear sections can be arranged so as to have a width equal to a width of the gas insulated switchgear and the width will not change even if the number of feeders in the metal enclosed switchgear sections is increased thereby enabling the entire power receiving and transforming system to be regularly installed at a site.

Dependent claims

A power receiving and transforming system comprising:

a gas insulated switch gear;
transformers disposed adjacent said gas insulated switchgear;
and
a plurality of metal-enclosed switch gears disposed on a side of said transformers opposite to said gas insulated switch gear,
wherein said metal-enclosed switchgears are divided into first and second sections each of said first and second sections comprising a plurality of metal enclosed switch gear units arranged in rows and juxtaposed with fronts of the respective metal enclosed switchgear units facing in the same direction, the direction of said rows of said first section and the direction of said rows of said second section are in parallel to each other and correspond to a direction in which said gas insulated switchgear and said transformers are juxtaposed, said first and second sections being disposed such that, in a direction perpendicular to the direction of said rows, said fronts of said first and second sections confront each other or surfaces of said first and second sections opposite to said fronts confront each other.
