Abstract

A modular system applied to transformers, particularly power transformers, which comprises a structure having modules coupled between each other by fixation means, in such a manner that, the set thus formed, is positioned in the perimeter of the tank of the transformer and to which it is possible to connect several equipment and components, so that the referred components and equipment are positioned in the interior of the tank of the transformer, thus permitting the access to the referred components and equipment, when carrying out maintenance, supervision or control work, as well as to permit the optimization in the manufacture thereof, assembly, transport and installation.

Dependent claims

A modular system applied to transformers, comprising:

a structure comprising a plurality of modules having different dimensions, each module comprising piping that forms a closed shape that extends around a perimeter of a transformer tank, each module being coupled to the transformer tank by means of flanged connections, wherein the piping of larger dimensioned modules and of smaller dimensioned modules are coupled between each other by means of flanged connections, wedge, blind flange and by fitting, and the piping of the larger dimensioned modules comprise in their interior outlines and channels and in their exterior rails and the larger dimensioned modules support ventilation and cooling systems in their horizontal piping and the smaller dimensioned modules, which are comprised of vertical piping and upper and lower horizontal piping, support auxiliary circuit boxes, monitoring systems and valve piping.
