Abstract:Uneven heating of the pantograph slide is the reason for limiting the pantograph removal of the maximum permissible long-term current from the contact network. The highest heating point is observed in the center of the pantograph head relative to the path axis, which can be taken into account when developing a pantograph slide cooling device. Existing models of the thermal state of the pantograph slide do not describe the transient modes of distributed heating of a closed-type structure (euro pantograph head) … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
