Electrical capturing system for train supplying and involving parameters

Abstract

Electric trains are powered by a current distribution device which depends on several parameters. The research works presented in this paper are located upstream of two types of important applications in the railway field: the electrical supply of trains involving the sliding or stationary pantograph/catenary contact and the famous problem of shunting of trains involving the wheel/rail rolling contact. These cannot be assumed without energy loss. In the case of train navigation, electric current can be transmitted by spots established between sources and the carbon strip. The quality of the pantograph/catenary contact obeys very strict specifications to ensure its maintenance, for permanent current connection. However mechanical aging of the contact and/or infrastructures, alteration of electrical contacts due to electrical arcing, the wear of collection strips during sliding, aging of the materials, are limiting effect for current flow. In this paper we will explicitly describe all the elements necessary to supply trains with electric current.
