Abstract

DC60 (04/11/41) power-saving transformer For currents with three phases With transfer device Pressure automatically In autopilot of a three-wire three-wire system or a three-wire three-wire system. Will be made special By winding one set or several sets of the primary winding according to the phase. Which will be connected to the input terminal on a three-phase core; Which the connection of the excitation coil Which are connected to each other in series to wire a type with a three-phase core between the ends of the primary winding. By means of a combination of hybrids; Several electrical switches are connected between the ends of the primary and excitation coil. Which will be switched on / off Where it depends on the value being detected By means of a voltage receiver connected to the lead inversion or eject connector, and the connection and disconnection between the ends of the primary and excitation coil by switching on / off the switch. Of electric switch Is a step on the same value of the voltage Or the current between phases in order to automatically change the output voltage In accordance with the voltage side Into the voltage transfer circuit In a manner that is not interrupted So when the input voltage drops or rises, it will be detected automatically. And the cycle will be changed So that the output voltage Being kept within the range of forces Predefined output voltage This will prevent the load from being hit. Power-saving transformers For currents with three phases With automatic pressure transfer device In automatic transformers of a three-wire system with three phases Or a four wire system with three phases Will be made special By wrapping one set or several sets Of the primary winding according to phase Which will be connected to the imported connector on a three-phase core Which the connection of the excitation coil Which are connected to each other in series to string a type with a three-phase core. Between the ends of the primary winding By means of a combination of hybrids; Multiple electrical switches between The ends of the primary and excitation winding Which will be switched on / off Where, depending on the value being detected by the receiver, the voltage is connected to the reverse terminal. Or lead out connector And connection and disconnection between the ends of the primary and excitation coil. By shuffling the on / off switch Of electric switch Is a step on the same value of the voltage Or the current between phases in order to automatically change the output voltage In accordance with the input voltage on the voltage transfer circuit In a manner that is not interrupted So when the input voltage drops or increases, it will be automatically detected and the circuit will be switched off. So that the output voltage Being maintained within a predetermined range of output voltage This will prevent the load from being hit:
