Study of Dependence of Nonlinear Acoustic Parameter in Transformer Oil on Medium Temperature

Autor: Aleksandr V. Konoshenko, Elena V. Shvedova

Publikováno v: 2019 International Russian Automation Conference (RusAutoCon).

The paper studies acoustic characteristics of the transformer oil at the temperatures close to real ones during normal operation of high-voltage oil-filled equipment. It considers and determines such acoustic characteristic as a nonlinear acoustic pa

Diagnostics of Defective Areas of Liquid Insulation of Oil-Filled Electrical Equipment with Structural Heterogeneity

Autor: Aleksandr V. Konoshenko, Elena V. Shvedova, Svetlana N. Trofimova

Publikováno v: 2019 International Russian Automation Conference (RusAutoCon).

The reliability of high-voltage oil-filled electrical equipment is largely determined by the quality of liquid insulation. An analysis of the technical state of the oil-filled equipment insulation is an extremely difficult task, since the insulation

Autor: Dmitry V. Zakharychev, Alexander A. Bredikhin, Zemfira A. Bredikhina, Larisa V. Konoshenko

Publikováno v: Tetrahedron: Asymmetry. 18:1964-1970

Five chiral arylglycerol ethers 2-R-C 6 H 4 -O-CH 2 CH(OH)CH 2 OH (R = OMe, OEt, OPr n , OPr i , OBu t ) have been prepared in racemic and enantiopure form. The melting points and enthalpies of fusion of every species were measured by differential sc

New example of spontaneous resolution among aryl glycerol ethers: 3-(2-hydroxyphenoxy)propane-1,2-diol

Autor: Dmitry V. Zakharychev, Alexander V. Pashagin, Zemfira A. Bredikhina, Alexander A. Bredikhin, Aidar T. Gubaidullin, Larisa V. Konoshenko

Publikováno v: Mendeleev Communications. 19:208-210

The conglomerate-forming nature of 3-(2-hydroxyphenoxy)propane-1,2-diol was established by IR, DSC, and XRD methods; racemic diol could be resolved by a moderate efficiency preferential crystallization procedure.
