NEW DEVELOPMENTS IN ROLLING STOCK AND POWER SUPPLY TECHNOLOGY

NOVOE V TEKHNIKE PODVIZHNOGO SOSTAVA I ELEKTROSNABZHENIIA

This pamphlet contains seventeen reports, which are enumerated below: automatic regulation of thermal conditions of transformers on semiconductor valves; wave processes in traction circuits, accounting for influence of the "two conductor-rail" system; parallel operation of AC traction substations of electrified railroads; research into rail potentials of AC traction networks; statistical voltage transformer for reserve feeding of the "Seima-3" protection system. No-contact measuring transformers in automatic control systems for recording wear and tear of rolling stock wheels; required frequency characteristics of DC traction substation smoothing mechanisms; reliability of apparatus of remote control electrical supply systems; experimental definition of slipping paths of locomotive wheel pairs; experimental research into dependence of transferable hydrocoupling moment on output pressure; calculation of body deformation of spray force pumps of type D100, D49, and IID45 diesels as the result of installation stress; investigation into protection of traction motors in transitional conditions on electric locomotives with electrical coupling of axles; increase in protection effectiveness of high voltage circuits from heating of passenger trains; investigation into possibilities for metallization by means of spray-coating as a method for the restoration of axle journals of wagon wheel pairs with roller axle boxes; influence of structural parameters on the tenacity of rail steel; hardenability of steel for highly stable rails; stability of results during the testing of stabilized steels for wear and tear.
