2 Sheets-Sheet 2 INVENTOR ATTORNEY Patented Feb. 18, 1930 UNITED STATES PATENT OFFICE ROBERT LB. GEORGE, OFSI-IARON, IENNSZLVANIA, ASSIG-NOR TO WESTINGHOUSE ELEC- TRIO & MANUFACTURING COMPANY, A LORPORATION OF PENNSYLVANIA REACTOR STRUCTURE Application filed May 10, 1329. Serial No. 361,946.
My invention relates to a winding or coil structure such as is utilized as a current-limiting reactor in an electrical circuit and more particularly to means for securing a reactor 6 coil to its support.
An object of my invention is to provide a reactor of improved construction wherein tie rods, which are usually employed to connect the end members together, are eliminated and the tension members are made integral parts of the support, whereby a strong, rugged and easily manufactured structure is ensured.
As an embodiment of my invention, I provide a reactor structure having separable end members, a suitable winding disposed therebetween and an adequate supporting means for said winding that is detachably secured to the end members.
For an understanding of my invention and for illustrations of some of the forms it may take, reference is made to the accompanying drawing in which,
Figure 1 is a view, partly in plan and partly in section, taken on the line 11 of Fig. 2,
Fig. 2 is a vertical sectional view taken on the line IIII of Fig. 1, looking in the direction of the arrows,
Fig. 3 is a vertical sectional view, similar 36 to Fig. 2, showing a modification of the means for detachably aiiixing the conductor-supporting structure to the end members.
Fig. A is a sectional view, taken on the line IVIV of Fig. 2, looking in the direction of the arrows, and
Fig. 5 is a perspective view of a horizontal spacing member.
Fig. 6 is-a perspective View of a modified form of a horizontal spacing member.
Referring to the drawing, a reactor 1 of any suitable character may have a supporting structure embodying insulating legs 2 and end plates 3 and 4. The winding 5 may be substantially of the character described in 'my copending application, Serial No. 234,385
filed November 19, 1927, and assigned to the Westinghouse Electric 8: Manufacturing Company.
The winding described in my aforesaid ap- 5 plication comprises a plurality of spiral conductor layers 6 disposed in superposed relation, the adjacent layers being supported by apertured horizontal spacing members 7 arranged in stacks or groups, all of which are disposed radially from the center line of the structure. The horizontal spacing members 7 are formed, preferably, of suitable insulating material and have the configuration illustrated in Fig. 5. The spacing members 7 are placed in superposed relation to a layer of the winding interposed therebetween, with their apertures in alignment. Extending between the adjacent convolutions of each layer of conducting winding and extending through the aligned apertures in the aforementioned horizontal spacing members 7 are vertical spacing members 8. The vertical spacing members 8 extend below the bottom layer of the winding and above the top layer of the winding. Spacing members 9 are located in certain of the spaces above and below the conductor layers, between the vertical spacing members. Any suitable holding means, for example, a bolt, as indicated at 10, extends through the spacing members 8 and 9 at both ends of the supporting structure, and each bolt has a nut 11 associated therewith.
The top and bottom end plates 3 and 4C are formed, preferably, of any suitable moldable material, such as concrete, which, if disposed in suitable molds, while in a fluid or semifiuid state, will retain, when hardened, the configuration imposed by the molds. The mold for the top end member 8 is of such shape as to provide passages 12 and 13. The passages 13 are for ventilating purposes and are in alignment with similar passages or apertures in the lower end plate.
After the winding is constructed according to my aforementioned copending application, it is set upon the lower end plate 4, a stud 14 having a hole to receive the bolt 10 is inserted in the passage or opening 12. Each stud 14 is provided with a nut 15 which may be turned to rigidly clamp the bottom portion of the conductor-supporting structure to the lower end plate 4. The space between the lower layer of the winding and the lower end plate is filled with a series of superposed apertured horizontal spacing members Terminals 18 and 19 of the reactor are attached to the bottom and top end plates 3 and 4, respectively, and serve to connect the,
reactor to a line conductor.
In Fig. 3 is llustrated another form of attachlng means for clamping the vertical spacing members of the winding supporting structure to the end plates. During the molding operation of the end plates, while the moldable material is still in a plastic or semiplastic state, openings or passages 20 are formed. At this time, recesses 21 may be formed or the end plate made substantially smooth. The reactance structure is clamped to the end plates 3 and 4 by means of U-shape metal supports 22, the base portions of which supporting members have apertures or openings 23 in their side walls through which the bolt 10 extends. The base portion of the U-shape members has an opening, or aperture, 24 which is in alignment with the pas sage 20. The U-shape support is inserted in the recess 21, and an attaching means, illustrated as a bolt 25, extends through the U- shape member 22 and the passage 20 and is provided with a nut 27, for securing the end plates 3 and 4 to the winding supporting structure. 7
It will be readily seen that, while the end plates are rigidly attached to the supporting are inserted in the recesses 21. The U-shape structure, it would be a simple and easy task to detach said plates if it should, at any time, become expedient or necessary.
From the foregoing description and disclosure, it will be evident that I have provided areactor structure which is rigid, rugged and easy to manufacture, and which eliminates the useof objectionable tie rods between the end members, and in which the tension members are integral parts of the coil-supporting -itructure. v 7
Since various changes and modifications may be made in the arrangement and assembly of the several features of my invention without departing from the'spirit and scope thereof, it is to be understood that no limitations are to be imposed, except those expressed in the appended claims.
