Abstract

A coil block fixation system (30) for a transformer comprises a coil block body to be coupled to a coil (19) of the transformer, and a supporting plate that is coupled to an upper surface (23) of the coil block body (10) opposite a bottom surface (24) of the coil block body (10). The coil block fixation system (30) further comprises two or more rods (3) that are coupled to an upper surface (21) of the supporting plate (1) opposite a bottom surface (22) of the supporting plate (1) for setting a load to the supporting plate (1) towards the coil block body (10). The supporting plate (1) and the coil block body (10) are formed geometrically in coordination with each other such that one comprise at least one recess (13, 14) and the other one comprise at least one protrusion (9, 16) that extends into the corresponding recess (13, 14) forming a respective movement limiter to counteract a translation and/or a rotation of the supporting plate (1) relative to the coil block body (10).
