<p>A high-voltage rectifier comprises, immersed in a reservoir filled with an electrically insulating medium, a transformer with a secondary sectioned winding, each section (7) of which is provided with a metallic screen and which comprises two coils (9), high-voltage tapping (27); rectifier elements (15) mounted on supporting insulators (25). Each section of the secondary winding of the transformer is connected to one of the rectifier elements (15) and forms a rectifier stage. The metallic screens are shaped as split metallic rings (10) between which are placed insulating rings (18). On the external surface of each of the metallic rings (10) are fixed windings (9) of one of the sections (7) of the secondary winding which are connected to the metallic ring (10) through internal tappings (11) of each of the coils (9) of the section (7) of the secondary winding. The metallic rings (10) and the insulating rings (18) are connected with each other by means of slots (15) and corresponding projections (16). </p> |
