To aZZ whom it may concern.-
Be it known that 1, Sun is'rinn ZIANI DE FERRANTI, a subject of the Queen of Great Britain, residing at St. Benet Chambers, Fen church Street, inihe city of London, England, electrician, hnvcinvented certain new and useful Improved Means for Distributing Electric Energy, ofwhich thefollowing is aspecilication.
Letters Patent on this invention have been granted to me in the following countries: in Great Britain, No. 15,141, dated December 9, 1885, and No. 15,251, dated December 11, 1885; in France, No. 180,176, dated December 9,1886; in Italy, No. 21,119, dated March 31, 1887, and in Belgium, No. 75,875, dated January 8, 1887.,
My invention relates to what are known-as. electrical converters, by means of which. currents of one intensity may be con verted into currents of a different intensity in all systems of distribution where such conversion is required-as, for instance, for electric lighting, motive power, &c.; and more especially my invention relates to systems in which dynamoelectric machines generating alternating currents of high intensity are employed and such currents converted into currents of lower intensity at or near the places where the lights are to be exhibited or the energy utilized.
In the accompanying drawings, Figure 1 is a plan, partly in section, of a converter in the form of a G ramme ring. The figureshows two forms-the one to the left and the other to the right of the figure. Fig.2 is a transverse verticcl section. I will describe first the arrangement shown on the left side of Fig. 1.
M is the central bundle of soft-iron strips or ribbons. These ribbons are insulated from each other by interposed layers of paper, or otherwise, and their ends are bro ughttogether in metallic contact. The core is thus formed of a bundle ofiron strips, each forminga continuous magnetic circuit. Over this there is applied an insulation, 'N, consisting of a lapping of paper and shellac. Upon this the copper spiral O is wound. Outside the copper there is another insulutiugcovering, P.
Q Q, are rings or windings formed of insulated wire, and they are coupled together to form the primary or dynamo circuit.
R is an outer covering ofinsulatcd material (N0 model.) Patontedin Eng and December 0, 1885, No. 15,141, and Deo. 180,176, in Belgium January 8, 1887, No. 75,815, and in Ital;
separating the rings Qfroin an pntside jacket, S, formed of thin sheets of soft iron, either made into rings or simply wound upon the outside of the converter, so as to form a magnetic circuit outside the rings Q continuous from end to end of the winding. T is asiinilar hoop or hoops of soft iron within the rings Q,andlthere also forming a closed or partially-closed magnetic circuit.
The description already given appliesto the arrangement on the left side of the figure. On the right side thepriinaryand secondary wires are wound upon the ring as an ordinary Gramme ring is wound. The former arrange. ment, however, is preferable, because the construction is easier, and also because ventile' tiou-spaccs are left, which is a matter of much importance, though no claim is made herein to such an arrangement. The ends of the coreribbons M are brought together after the coils or rings are upon them, and the two ends of each ribbon are placed in metallic contact, while by an insulation of paper each ring is separated from its neighbor. The part of the ring in which this overlapping takes place is preferably left unwound.
This invention is in some essarily limited to the core being made up of a bundle of strips, each forming an independent magnetic circuit, because, so far as I am aware, I am the first to use a core having its ends united to form a closed magnetic circuit in connection with one or more independent exterior magnetic circuits or rings or layers of iron, and I have accordingly claimed such matter in the third claim below recited.
The converters which I have described in this specification may be used not only for reducing from a high tension to a. low, but also for increasing from a. low tension to a. high or simply for transferring energy from one circuit to another. I make these converters of all sizes, from a few ounces in weight for telephonic useand for other purposes \there'thc amount of electrical energy to be converted is small up to a ton or more in weight,whers the electrical energy to be converted islarge. Beyond the latter dimensions it may perhaps he more convenient to employ several converters to supply'thc some main circuit.
