umspannstation for underground energieverteilungsnetze

摘要

Transformer centre, intended, although not exclusively, for use in underground medium voltage electrical networks. The centre is characterized in that it allows the upper roof to be completely replaced without affecting the urban area that surrounds it. The design of the roof, made up of three slabs, allows the use of metallic framework to be avoided, while maintaining the watertightness of the seal. Furthermore, the use of a removable paneled floor in the work and cable suspension area allows the depth of the excavation necessary to house the centre to be reduced. Finally, the placing of the transformers in the sides allows the substitution of one of them to increase the number of medium voltage cubicles in the centre and to effect a complex electrical design.
