HIGH-VOLTAGE RECTIFIER TRANSFORMER Russian patent published in 2015 - IPC H02M5/00 H02M5/27 H02M7/04 H01F38/00 H01F38/06 

FIELD: electricity.

SUBSTANCE: device assembled as per the three-phase bridge rectifying scheme contains additionally a dielectric rod installed in the centre of the three-phase transformer with thread surface at a loose end and a nut fixing in series the first collecting washer, the first high-voltage capacitor, a metal washer, the second high-voltage capacitor, the second collecting washer as well as dielectric centring washers, which are mounted in the central cylindrical openings of the collecting washers and metal washer. At that thickness of the dielectric centring washers corresponds to thickness of the collecting washers and metal washer, wherein they are mounted. Beginnings of the secondary windings are wye-connected by the metal washer, while ends of the secondary windings with respective anodes of semiconductor rectifiers in the cathode group and cathodes of semiconductor rectifiers in the anode group are soldered. The cathodes of semiconductor rectifiers in the cathode GROUP are connected by the second collecting washer.

EFFECT: improving breakdown strength of the device.
