REGULATOR SYSTEM.
Application mm September 16, 1921. Seria1 m. 501,144.
T all whom z't mag; concern:
Be it known th'at I EDWIN E. LEER, 'a citizen of the United tates, and a resident of Wilkinsburg, in the county of Allegheny and State 015 Pennsylvania, l1ave invented a new and useful Improvement in Regulator Systems, of Which the following is a specification.
My invention relabes to regulator systems and it has speoial relation t0 means associated therewith to compensate for variations in a supply circuit by reason of variations in the loadthereupon.
\ One object of my invention is to provide a. compensatory means of the above-indicated character which shall be relatively simple and compact ih construction and eflicient and reliable in operation.
Another ob'ect of my invention is t0 pro vide means 0 the abWe-indicated character panying drawing, wherein panel for the compens'ator.
60 with the voltage of t The princi 1es of the present inventionwill be descri ed in conneetion with an inductiori regulator but it will be understood thatsuch description is illustrative only.
An induction regulator of well-known construction is indieated at 1 and has a; eurrent coil 2 ancl a voltage coil 3. The regulator is controlled b a. reversible motor 4, whi ch is energized om conductors 5 sonnected to any convenien't source of power; through gearing 10. Reversing switches 6 and 7 govern the operation of the motor 4 in the one or the otherdirection. The coils 8 and 9 of the reversing switches a're respectively connected tocontact mernbers 11 and 12 which are eontrolled by the operation of a pivoted lever 13 having a control magnet 14 secured thereto. The coi1 15 0f electromagnet 14 is ener ized, in accordance e supply circuit, through a voltage tra'nsformer 16. The illustration 015 the induc tion regulator and its control apparatus is diagrammatic since its specific structure is not a part. of the present inventi0n.
rel-ation with the coil 15 pf control magnet 14, and includes a transformer 18, the pri mary Winding 19 of Which is energized fr0m the supply circuit thr ough a, current trans- .former 21. The leads 23 and 24 015 the secondary winding 22 of transformer 18 are connected, resp6ctively, to control levers bearingthe same refernce numerals and loeated upon the contr0l panel 20 (Fig. 2), for a purpose to be hereinafter explained. A reactance coil 25, WhlGh' constitutes the primary Winding of a reactance transf0rmer 26, is connected in series relation with the primarywinding 19 of transformer 18. The w1nding 25 comprises a plurality of sections divided by a series of taps, indicated at 27 28, 29, 30, 31, 32, 33, 34, 35 and 36. It will be noted that taps 27 to 31, inclusive, embrace relatively small sections of the winding 25, whereas taps 32 to 36, ii1clusive, embra;ee relatively large sections of the winding 25. The taps 27 to 36, inelusive, are electrieally connected to the contact laut tons 2710 36, inclusive,of the eontrol panel 20. "Control levers 37 and 38 engage with the contact butoons 27 to 36 to determine the number 01 energized sections of the winding' 25.
The secondaiy winding 39 of the reactance transformer 26 is connected in series relation With the coil 15 of the control magnet 14. A variable resistor 41, having 21 series 0f taps therefrom, indicated at 42, 43,
- 44, 45, 46, 47, 48, 49, 50 ancl 51, respectively,
is connected in series relation With the secondary winding 39 and also in series relation with the coil 14 of the control magnet. It Will be noted that taps 47 to 51, inclusive, embrace relatively small sections of the resistor 41, whereas taps 42 to 46, vinclusive,
embrace relatively large sections of the resistor 41. The taps 42 to 51, inclt1sive, are
electrically conneeted to the contact buttons 42 to 51, inclusive, 0f the control panel 20. The control arm 24 selectively engages contact buttons 42 to 46, inclusive, ancl contfol arm 25 selectivel y engages contact buttons 47 to 51, inelus1ve.
It is well known that, when the distributiori point is removed from the transm'1ssion line regulator, variations in load produce variations in drop in the feeder cir cuit. With the present' invention, the compensation includes both reactance and resistance elements to maintain a .constant voltage at the center of distribution. Also,
in the present invention, steps of di:lferi1t sizes enablevariations of difl'ering degreea to be efi'ected.
When no compensation is required, the ontrol arm 24 will e'ngage contactbutton 46, and control arm 23 will engage cntact Control arms 37 and 38 will respectively engage contact-buttons 27 and 36. Vhen maximum compeusationis required, control arm 24 will iengage contact button 42, and control arm-23 will engage contact button 51. Control arms 37 and 38 will respectively engage contact buttons 31 and 32. Obviously, an interr'nediate steps bet ween no compensation and full compensation u1ay be' obtaiined, the coi1i;rol arms .38 and 24 g iiihg relativelylarge steps Cf comp'ei1sati'on, and control arms3'i and 23 givi-ng the intermediate sfebs.
