DETERMİNATİON OF TECHNICAL FEATURES OF THE NEW GENERATION ELECTRIC CARRIERS OF THE AZERBAIJANI RAILWAY

Abstract

The main issues facing the locomotive economy were examined at the AzerbaijanRailways CJSC and the existing logistics base of the locomotive park was analyzed. It was expedientto purchase new locomotives showing the age structure of the Locomotive Park. For this purpose,the development of technical requirements for the production and commissioning of new locomotivesand motor vehicles, as well as the development of material and technical basis for the technicalmaintenance and repair system, as well as the development of advanced repair technology.The ATD uses the Az4A and Az8A electric locomotives from the new power circuits of staticconverters of electric motors in the main electric locomotives, and the functional circuits andenergetic diagrams of locomotives are installed. The use of asynchronous traction motors in newlocomotives is 1.5 times higher than the engine power compared to the constant dynamics of directcurrent; This allows you to increase 2.0 times, ATD can operate at rated power at all speeds, use lessnon-ferrous metals, use less environmentally friendly materials, reduce the complexity of repair andmaintenance. At the same time the number of locomotives decreases and the reliability and servicelife of locomotives increases. One of the main innovations in the new electric locomotives is thecorrect choice of structural schemes of traction transmission in the transmission of motion for thesupply of ATD.Functional diagrams and power schemes of locomotives are constructed using power supplycircuits of static converters of electric static electric locomotives in the main electric locomotivesusing electric locomotives Az4A and Az8A. The article analyzes the existing material and technicalbase of the locomotive fleet in the system of Azerbaijan Railways. The structure of the locomotive fleet and the tasks facing it are determined. The launch of international transport corridors and thegrowth of Azerbaijan's economic capacity have increased the demand for freight and passengertraffic. To this end, in connection with the purchase and commissioning of new locomotives andvehicles, the issues facing the Azerbaijani Railway will be resolved. As a result of the operation ofnew locomotives, the efficiency of the railway transport process will increase and train safety will beensured. In connection with the commissioning of new locomotives in the locomotive industry, thefollowing complex issues will be considered.
