HIGH TENSION TRANSFORMER Filed June 7, 1928 q II f a Fig.3. b c
% 777/erha Patented June 14, 1932 UNITED STATES PATENT OFFICE AUGUST MEYERHAN S, OF ENNETBAJJEN, SWITZERLAND, ASSIGNOR TO AKTIENGESELL- SCHAF'I" BROWN, BOVERI AND CIE., 0F BADEN, SWITZERLAND i HIGH TENSION TRANSFORMER Application filed June 7, 1928, Serial No.
It has already been proposed in a high tension transformer having cylindrical windings to enclose only the windings on each wound column in a vessel filled with insulating material and consisting of insulating material. The high tension winding has its highest potential in the middle of the vessel its ends being led out of the vessel, one in the middle thereof and the other at at least one of the vessel ends without a leading out insulator. The vessel thus surrounds the windings only, while the column part of the iron core extends through the hollow central space of the vessel and remains dry.
According to the invention, for high tension transformers, while retaining the oil vessel of insulating material surrounding the windings, the potential distribution and the terminal arrangement of the high voltage side, the iron core is also provided with oil cooling means, being also enclosed in the oil vessel.
In the accompanying drawing, two constructional examples of the invention are shown diagrammatically in longitudinal section and plan view, Figs. 1 and 2 showing the arrangement in which two limbs of a transformer are wound and Figs. 3, 4 and 5 an arrangement in which one limb is wound. Figs. 1 and 2 show a transformer having its two columns wound, the parts forming the columns being both enclosed in insulating cylinders c. In the middle of the same are the high tension terminals 7) of the high voltage winding a. The column parts m of the iron body 2' with their concentric low tension windings k lie each in the axis of the insulating vessel 0, while the yokes n lie in iron vessels p and g which are connected in an oil-sight manner to the cylindrical insulating vessels 0. The free space 0 separates the two limbs 0 of the vessel 0, p, 0, g. The lower part ;0 forms the bottom of the vessel, the upper part 9 being closed by a cover 7" and the liquid spaces in all the parts communicate freely throughout. In order to avoid induced currents in the metal parts p and g, longitudinal gaps s are provided in these parts, preferably where the cylinders c are nearest together, which gaps are filled 283,700, and in Germany June 13, 1927.
with insulating material and are made oiltight.
According to Figs. 3, 4 and 5 the opening 0 is omitted and the two columns of the iron core together with the winding are enclosed in a single insulating vessel 0. In this example only one of the two columns m of the transformer is wound. The insulating vessel 0 may either be of oval cross-section, as shown in Fig. 4 or as shown in Figure 5, of round cross-section. The bottom part ;0 and the upper part 9 with its cover 1" are in this case simple one-part bodies, similar to those used in ordinary oil transformers. They differ from the latter only in the insulating vessel 0 with the high voltage terminal 6 being led directly out of the middle without an insulator. The parts p and q of the box may be provided with cooling ribs or a water-cooled casing (t in Fig. 3). These parts may how ever be made of insulating material, just as the cylinder 0. The whole vessel may in this case be made in a single piece in a known manner.
lVhat I claim is:
1. A transformer having a rectangular shaped core carrying a high and low tension winding, a casing containing an insulating liquid and totally enclosing said transformer, the said casing being partly metallic and partly of insulating material, the part surrounding the windings being of insulating material and arranged in close proximity to the windings, the said high tension winding having its high potential end midway along its axial length and connected to a high tension terminal arranged midway along the axial length of the insulated part of the. casing which latter forms the sole leading-in insulator for the said high tension terminal.
2. A transformer as claimed in claim 1 wherein one leg only of the rectangular shaped core carries a winding.
3. A transformer as claimed in claim 1 wherein a plurality of the legs of the transformer carry windings.
In testimony whereof I have signed my name to this specification.
AUGUST MEYER-HANS.
