REGULATING SYSTEM Filed March 25, 1926 Inventor:
Vincent M. Mon'tsinger,
His Attorney Patented Apr. 29, 1930 UNITED STATES PATENT, OFFICE VINCENT I. MONTSINGER,
ELECTRIC REGULATING SYSTEM Application filed March 25, 1926. Serial No. 97,445.
My invention relates to regulating systems and particularly to a system for obtaining a constant alternating current voltage from a variable voltage source of alternating current and its object is to provide an improved arrangement for accomplishing this result.
In accordance with my invention, I provide a transformer which has its primary winding connected in series with an impedance across the variable voltage source and its secondary winding connected to the circuit across which it is desired to maintain the voltage constant and means for varying the reluctance of the magnetic circuit of the transformer in response to the suppl voltage so that the voltage induced in t e secondary winding remains substantially constant.
My invention will be better understood from the following description, taken in connection with the accompanying drawing, and
its scope will be pointed out in the appended claims.
In the accompanying drawing, which shows one embodiment of my invention, 1 represents a source of alternating current, the voltage of which varies, and 2 represents a distribution circuit, such as a lighting circuit, across which it is necessary to maintain the voltage substantially constant. In'order to maintain a substantially constant voltage across the circuit 2, I provide a transformer 3 which comprises a stationary core member 4 and a movable core member 5 which is arranged to be actuated by an electromagnet 6. The electromagnet 6 is connected across the variable voltage source 1, so that the air gap between the two core members is in- 4 creased when the source voltage increases and is decreased when the source voltage decreases. The electromagnet 6 acts against a biasing spring 7 which tends to pull the two core members together. The electromagnet 6 and spring 7 therefore coact to increase and decrease the reluctance of the magnetic circuit of the transformer as the supply voltage varies.
The primary winding 8 of the transformer is connected in series with an impedance 9,
shown as a reactance, across the source 1 and the secondary winding 10 of the transformer is connected across the load circuit 2. These Windingsmay be wound on the same or different core members as desired.
The operation of the arrangement shown in the drawing is as follows :When the voltage of the source 1 is normal the electromagnet 6 is so designed that it maintains the core members separated a predetermined amount so that the current in the primary circuit has a certain value for a given load connected across the secondary circuit 2. This primary current produces a voltage drop across the reactance 9 so that the proper voltage is impressed upon the primary winding 8 to cause the proper voltage to be induced in the secondary winding 10.
When the voltage of the source 1 increases, the electromagnet 6 increases the air gap be tween the two core members 4 and 5 so that the reluctance of the magnetic circuit of the transformer is increased. Consequently, the
primary exciting current increases and the voltage drop across the impedance 9 is increased. The magnet 6 and spring 7 are so arranged that for any increase in the supply voltage the air gap is increased the necessary amount to increase the voltage drop across the impedance 9 substantially the same amount as the supply voltage increases. Therefore, the voltage impressed upon the rimary winding 8 and the voltage induced in the secondary winding remain substan tially constant.
The arrangement operates in a similar manner to decrease the air gap when the supply voltage decreases, so that the primary exciting current is decreased the necessary amount to produce a decrease in the voltage drop across the impedance 9 which is substantially equal to the decrease in the supply voltage.
\Vhile I have, in accordance with the pat ent statutes, shown and described one particular embodiment of my invention, changes and modifications will be obvious to those skilled in the art and I, therefore, aim in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of my invention.
- What I claim as new and desire to secure by Letters Patent of the United States, is
1. In a regulating system, avariable voltage source of alternating current, a load cir-. cuit, a transformer having a primary winding connected across said source and a secondary winding connected across said load circuit, an impedance connected in series with said primary winding, and means responsive to the voltage of said source for'varymg the reluctance of the magnetic circuit of said transformer.
2. In a re ulating system, a variable voltage source 0 alternating current, a load circuit, an impedance, a transformer comprising a primary winding connected in series with said impedance across said source, a secondary winding connected across said load circuit, a stationary core member and a movable core member, biasing means arranged to maintain said core members together whereby the reluctance of the magnetic circuit of said transformer is relatively low, and
electrores onsive means responsive to the voltage 0 said source arranged to move said core members apart to increase the reluctance of the magnetic circuit of said transformer. In witness whereof, I have hereunto set my hand this 22nd day of March, 1926.
