Definitions

  • My invention relates to electrical apparatus comprising wholly or in part a winding.
  • object of my invention is to provide such electrical apparatus in which the reactance and the stresses due to the magnetic action are uniform in their distribution, or more nearly uniform than heretofore.
  • Another object of my invention is to provide an improved high current winding, and electrical apparatus comprising a high current winding, having taps whereby the voltage of the high current winding may be varied with a minimum unbalancing of the reactance and of the stresses due to the magnetic action.
  • Still another object of my invention is to provide a method of operating an electrical winding whereby the reactance and the stresses due to the magnetic action are continued uniform, or more nearly uniform than heretofore, as the number of operating turns is increased or diminished.
  • My invention is particularly applicable to electrical apparatus comprising wholly or in part ahelical winding wherein a plurality of conductors are disposed one outside another in coil groups, and also is particularly applicable to transformers in which there are a plurality of windings. It will be understood, however, that my invention is not limited to such a winding or to such a device, but from a broader aspect comprehends as well any other winding and any other apparatus in which there is a winding in which conductors in different coil groups are, in effect, connected in series to form a plurality of lots of series connected conductors traversing the same coils.
  • Fig. 1 While Fig. 3 is 3. dia rammatic vie illustrating the mode of ciinnections 811i ployed in Fig. 2.
  • the low voltage winding 5 is in the form of a helix.
  • Each turn of the five conductors forms in efli'eot a coil or coil group of a plurality of conductors, these coil groups 16, 17, 18, 19 and 20 being separated from each other, as appears from both ig. 1 and Fig. 2, for the purpose of providing ventilating spaces whereby the heat ge'nerated within the conductors 10-14 is more readily dissipated.
  • terminal 25 which is connected directly to conductor 12; as will be seen especially from Fig. .2, and as before indicated, conductor 12 occupies or constitutes the central layer and turn of each coil group.
  • Terminal 25 is connected to the lower end of the conductor 12, and the upper end of conductor 12 is connected to tap 26.
  • a terminal or connection board 27, suitably supported from the core 1, is provided for supporting in proper relation terminal 25, tap 26, and the other taps and terminals hereinafter described in connection with winding 5.
  • Terminal 26 comprises also, or is attached to, connector 29 through which the upper end of conductor 12 is connected to the lower end of conductor 11.
  • This connector 29 (like the other connectors hereafter mentioned) extends across the face of the low voltage winding 5, that is external to the same and from one end of the winding 5 to the other end thereof.
  • the opposite end of conductor 11 is connected to tap 30, resembling tap 26, and connector 31. like connector 29, connects the upper end of conductor 11 to the lower end of conductor 13.
  • the two conductors 11 and 13 are at opposite sides of conductor or layer 12 and are, radially, the nearest conductors and layers to the more central layer 12.
  • the upper end of conductor 13 is connected to tap 32 and by connector 33 is connected to the lower'end of conductor 10.
  • conductors 10 and 13 are at opposite sides of the central layer or conductor 12.
  • the upper end of conductor 10 is connected to tap 34 and by means of connector 35 is connected-to the lower end of the'remaining conductor and the conductor or the opposite side of and symmetrically related to conductor 12, namely, conductor 14.
  • the upper end of conductor 14 is connected to terminal 36.
  • the reactance or action of the leakage flux is also substantially the same (except for intensity of effect) whether the five conductors are active or whether only the four conductors are in operation. If it is necessar to still further reduce the number of actlve conductors by one, the connection to tap 34 is broken and the corresponding connection made to tap 32. With this arrange ment the circuit is completed through conductors or layers 12, 11, and 13 only, and in that order counting frolnterminal 25.
  • the conductor or layer 12 being the most central layer of the winding, when it is necessary to reduce the number of conductors by one I cut out one of the conductors or layers'farthest removed from the conductor 12, namely conductor 14 in the first instance above.
  • the number of active conductors I again out the active conductor or layer farthest removed from 12, and the active conductor located similarly to conductor 14 but on the opposite side of la er 12, namely conductor or layer 10.
  • WV henever it is possible to reduce the number of layers or conductors by two, I simultaneously cut out those two layers at opposite sides of and farthest removed from the central layer or conductor 12, such as conductors 10 and 14.
  • a winding comprising a plurality of coil groups in which conductors in each group are disposed one outside another radially and connected respectively in series with conductors in another coil group to form lots of series connected conductors, the lots being connected in series and taps for the windings being provided between each lot of conductors.
  • a winding comprising a plurality of coil groups in which a plurality of conductors in each group are disposed one outside another radially'and each of said plurality of conductors of each of said coil groups is connected in series with the similarly located'conductors in the other of said coil groups to form lots of conductors, the lots of conductors being connected in series and taps for the winding. being provided between each lotvof conductors.
  • a winding comprising a plurality of conductors disposed as a helix and one outside another radially, a conductor near the center of the coil groups providing one terminal of the winding, a connector from the opposite end of said conductor connecting the said conductor in series with a conductor at one side thereof, a connector connecting said second conductor in series with a conductor at the opposite side of the first mentioned conductor, and a tap for the winding connected thereto adjacent the first mentioned connection.
  • a winding comprising an odd number of conductors disposed as a helix and outside another radially,the center conductor providing one terminal of the winding, a. connector from the opposite end of said conductor connecting the said central conductor in series with a conductor immediately at one side thereof, a connector connectin said second conductor series with a 'con uctor immediately at the opposite side of the central conductor, other connectors completing the series connection of the conductor of the winding by similarly cross connecting pairs of conductors at opposite sides of the center conductor, and taps for the windings connected thereto adjacent each connector.
  • Electrical apparatus comprising a core, a winding thereon, and a second Winding on said core inductively related to the first mentioned winding, said second winding comprising a plurality of coil groups in which conductors in each group are connected in series with conductors in another coil group to form lots of series connected conductors, connectors extending from one end of the winding to the other connecting said lots of conductors in series, and taps for the windings connected thereto adjacent connectors.
