COMPLETE MULTIPLE-UNIT TRANSFORMER SUBSTATION Russian patent published in 2015 - IPC H02B7/06 E04B5/04 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering, to power engineering sites, power transmission lines and can be used at manufacture of transformer substations. A complete transformer substation, in which transformers, high-voltage and low-voltage electrical equipment is arranged, includes three units: a middle one and two side ones, which are mounted together by means of fastening bolts. Each unit is made of a framed housing covered with panels. Walls are of a blind type; the middle unit has only a rear wall, and the side units have rear and side external walls. Front walls of all the units are equipped with single-leaf doors at the side units and with double-leaf doors at the middle unit. After the units are installed, the substation can have overall dimensions of 7×5×3 metres under a common heat-insulated double-pitch roof. All the external blind walls and walls with doors of all the units are heat-insulated. Attaching walls of all the units (two side walls of the middle unit, and one side wall of each of the two side units) are of a framed shape without any covering with panels for easy installation and maintenance of electrical equipment inside the substation.

EFFECT: improvement of ease of operation.
