| titleOfInvention | ELECTRICAL TRANSFORMER, IN PARTICULAR FOR A ARC WELDING STATION |
| abstract | THE PRESENT INVENTION CONCERNS A MOBILE ELECTRIC TRANSFORMER COOLED BY DIRECT EXCHANGE WITH A CURRENT OF AIR GENERATED BY A FAN. IN ACCORDANCE WITH THE INVENTION THE FAN IS CONSTITUTED BY AT LEAST TWO TRANSFORMERS 1 WITH MAGNETIC CIRCUITS 2 INDEPENDENT OF WHICH THE PRIMARIES 3, ON THE ONE HAND, AND THE SECONDARIES 4, ON THE OTHER HAND, ARE CONNECTED IN PARALLEL AND, PREFERENCE, INCLUDED. , IN THE PRIMARY CIRCUIT 3 OF EACH TRANSFORMER 1, A BILATERAL TRIODE 19 SWITCHING DEVICE WHOSE ELECTRODE IS CONTROLLED BY A DIVIDER-DEPHASER CIRCUIT WHOSE RESISTANCE IS A VARIABLE RESISTANCE 22 SENSITIVE TO THE OPERATING TEMPERATURE OF THE TRANSFORMER. THERMISTANCE. THE INVENTION ENSURES AN INCREASE IN THE TRANSMITTED POWER FOR THE SAME COST PRICE. |
