ABSTRACT:
Disclosed is a power distribution substation for power distribution to a consumption pool having a high voltage unit divided into cells, each cell containing high voltage incoming connection equipments connected by high voltage cables to a power source having a voltage between 60 kV and 245 kV. The substation also has a transformers yard having at least one transformer connected to the high voltage incoming connection equipments, and a mid-voltage unit containing outgoing connection equipments connected to the transformer and linked to output power lines for power distribution under a voltage lower than or equal to 36 kV. Finally, the substation has a control room. The high voltage and mid-voltage units, the transformers yard and the control room are located in a single building having a roof where the high voltage incoming connection equipments, the transformer(s) and some of the outgoing connection equipments ate located at the same level inside the building. The substation includes an access passage that forms an integral part of the building. The access passage is designed to insure direct access to the cells of the high voltage unit, the transformers yard and the mid-voltage unit. The roof over the transformers yard has slats that may be opened and closed in order to allow cooling of the transformer(s) or recuperation of the heat generated by the transformer(s) whenever necessary. Preferably, the outgoing connection equipments of the mid-voltage unit are of the self-relieving switchless type and incorporate a removable circuit breaker permutation system. The substation is extremely compact, is of easy maintenance and is soundproof. It is non-polluting as it may have an oil retention system. This substation is thus particularly well adapted for urban use, while offering unlimited architectural designs.
