PERIODICAL: Vestnik,e.lektropromyshlennosti 19599 Nr 8, pp 73-71- (USSR) ABSTRACT: A.session of the Temporary Commission on.Transformer Con- struction-was held under the Chairmanship of Engineer S.I. Rabinovich to consider the maia characteristics of a series of small and medium-output transformers with aluminium windings. The session was attended by represen- tatives of research and design institutes, GOSPLAN USSR, GOSSTROY USSR, the Cormittee of Standards and Measuring Instruments, the Ministries of Power 'Stations,, Agriculture - and Communal Economk of the RSFSR and also transformer manufacturers-and users.from. Moscow, Leningrad, Sverdlovsk, Zaporozhtye, Yerevan and other towns. The report of Engineer LoM. Shnitser noted the tendency to use aluminium instead of copper for small and medium transformers but not for large because of the high resistivity and low mechanical Card 1/3 Maw SOV/110-59-81--20/24 .,A COnference on Transformer Construction. strength of aluminium. The amounts of material-required for_.. transrormers of different sizes with copper and aluminium windings were compared and the use of aliminium was re- commended for small transformers. Engineei M.G. Gukasyan described the development of a series of transfornters of the first frame size using alminium windings, The dimensions were,20% greater than for the corresponding transformer with copper winding; the total weight was 5% _--greater-and- -the--- Must be used for,the cores. 'Engineer I.S. Kaliniohanko described the,dasign of a 1000 kVA 10 kV-transformer with aluminium windings using a core of hot-rolled steel. Several types.of transformer were designed and some of them were made; the leading characteristics are tabulated. The author considers it possible to construct transformers with, aluminium windings, but the manufacturinq costs for.the materials and labourwill be more expensive and the total costs from 5 to 10% greater than for trwisfonaers Ath copper windings. The scale of rdtiags shou.1d, however, be revised. EngIneer K,K. Balashov noted tits possibilitr of Card 2/3- S.OV/110-59-8-20/24 A Ponference on-Transformer Construction-4 reducing transformer losses by the use of aluminium windings.

The economy-of copper that would result from ooaverting power transformers of outputs-up-to 180 kVA to aluminitm windings -would be about 3600 tons per year: if all *small and medium transformers were made-with aluminimn windings the economy of copper should be.at least 25000 tons~during the Seven Year Plan, A fmrther 20% economy of copper would accrue if power transformers of up to 5600 kVA viere~to be designed with aluminium w1indings. Cold-rolled steel. should be used in transformers with aluminium windings. There is 1 table. Card 3/3 IFANIYUO G.G*9 iwh.; Pamcael". m.i, inzh,;, auLr-um,.,PB,.., YATSIM, A.Ge; ZARWO~ G.,740 iazh.

They disturb the reaction of uranium~and decrease its yield. It is *ith a view to stud~y these dis- turbingef4f"eCtS that the change of the thermodynamic potential AF~o ir. the reactions quoted-in Table 2 hasbeen calculated for different in- tervals of temperature, starting data being taken from Table 1. The calculated temperature dependence of the free energy of potassium and sodium fluorides on reaction with calcium and magnesium is represented in the attached diagram.

Tba alloys were pr6auceVIrom 99~9 ~a pure rare earths and fromspeotrally pijre leads, The method 01sed permits a determination of the activity ai of one of thealloy componerits and the variation of the chemical potential during the formation:~of the alloy according to the formula: &jLi -RT,lnai. The evaporation :rate of lead from the alloys .(which is proportonal to the vavor~preasure)' was measured between 700 and 9000C; ai for lead was calculated for 7,2iD-8000C (Table 1). According to known formulas thei authors further deterinined the partial enthalpies and entropies of alloj- formation, and the in;~kegral enthalpies and entropies of the alloy formation by graphical intej;ration of the Dyugem-Margules equation. The.latter enthalpies.of all lihree systems were found to be only slightly different. It is conclude4i -therefrom that the interactions of the three rare earths studied with lea:d belong to the same type. The negative sign of the entropies of alloy f''ormation is related-to the sign. of the formation enthalpies, iae., to a strengthening of interatomic bonds Card 2/4 m 1-14 -Pb~. ~ ~ There JAre - I I-f igure 3 t6blegi, and , , 0 d *i oc The referonoe-to ~ --I ,.c an non-Sovilet-bl - - -. .cation is given tvq the body of , the abstract. , ~ ;- I . 7 1~ Vs.
