Abstract

Un dispositivo per fissare in modo amovibile ad un trasformatore un raddrizzatore a diodi raffreddato, con i diodi riuniti in una colonna, presentante corpi di raffreddamento e munito di un raffreddamento forzato per smaltire il calore elettrico dissipato su ogni due lati dei diodi ha un corpo di raffreddamento parallelepipedo che poggia su di essi con pressione e che è munito di un sistema di canali per un liquido di raffreddamento. Ogni secondo corpo porta un pezzo conduttore formato in un pezzo a gomito con cui tali corpi sono avvitati al trasformatore ciascuno tramite un'ala del pezzo a gomito. Ogni secondo degli altri corpi porta un pezzo conduttore pure formato come elemento a molla, però ruotato dal piano di fissaggio degli elementi conduttori al trasformatore di 90° rispetto agli altri e avvitato allo stesso modo alla barra collettrice di corrente continua in altri punti.A device for detachably fixing a cooled diode rectifier to a transformer, with the diodes united in a column, having cooling bodies and equipped with forced cooling to dispose of the electric heat dissipated on each two sides of the diodes has a body of parallelepiped cooling that rests on them with pressure and which is equipped with a system of channels for a cooling liquid. Each second body carries a conductive piece formed in an elbow piece with which these bodies are screwed to the transformer each by means of a wing of the elbow piece. Each second of the other bodies carries a conductive piece also formed as a spring element, however rotated by the plane of fixing of the conductive elements to the transformer by 90 ° with respect to the others and screwed in the same way to the direct current busbar at other points.
