Abstract

Transformateur compact utilisant de l'huile de silicone comme diélectrique liquide. Il comprend un couvercle amovible 30 pourvu d'une chambre d'expansion 32 étanche aux liquides dont l'intérieur communique librement avec l'intérieur de la cuve étanche aux liquides 26, une poche 40 placée dans la chambre et munie d'une ouverture 42 communiquant avec une ouverture 34 pratiquée dans la chambre et un diélectrique liquide 50 remplissant la cuve et l'espace compris entre la poche et la chambre d'expansion. Application aux transformateurs pour moteur à traction.Compact transformer using silicone oil as the liquid dielectric. It comprises a removable cover 30 provided with a liquid-tight expansion chamber 32, the interior of which communicates freely with the interior of the liquid-tight tank 26, a pocket 40 placed in the chamber and provided with an opening 42 communicating with an opening 34 made in the chamber and a liquid dielectric 50 filling the tank and the space between the pocket and the expansion chamber. Application to transformers for traction motors.
