Study of the basic criteria of the pantograph and overhead line interaction in operating conditions

Abstract

In this work, the basic criteria of the process of the pantograph and overhead line interaction of railway rolling stock are considered. An analysis of the causes and consequences of impaired current collection was also performed. The analysis of existing systems and technical means for determining the qualitative and quantitative indicators of the pantograph and overhead line interaction was carried out and their classification was carried out according to the location, the principle of obtaining information and controlled parameters. Based on the results of research, the main quantitative and qualitative indicators of the interaction of current collectors with the overhead line in the conditions of operation on the railways of Ukraine, which should be subject to control, have been established. Field tests were also conducted to determine such indicators in real operating conditions of railway rolling stock. According to the results of the research, an experimental complex was developed to determine the indicators of the interaction of current receivers of various types of rolling stock with the contact network in operating conditions.
