21、10 Introduction The electrical power supply of a tractive unit is achieved by the collection of current from the contact wire by means of one or more pantograph(s), installed on the traction unit or on the vehicle. The contact strip of the pantograph which slides along the contact wire facilitates t
22、he transmission of power. The pantograph and the overhead line equipment form two oscillating sub-systems which can be displaced. There exists a unilateral sliding linkage between them, which shall ensure continuous contact. Their design shall allow for minimum wear of both sub-systems when used. BS
23、 EN 50206-2:2010EN 50206-2:2010 6 1 Scope This European Standard defines the general assembly characteristics which are to be applied to pantographs, to enable current collection from the overhead line equipment. It also defines the tests the pantographs have to perform, excluding insulators. This E
24、uropean Standard does not apply to pantograph dielectric tests, which are to be performed on the pantograph installed on the vehicle roof. If no other requirement is agreed between customer and supplier, insulation coordination according to EN 50124-1 may be used. This European Standard does not app
25、ly to pantographs used on main line vehicles: these pantographs are considered in EN 50206-1. This European Standard relates to conventional suspended overhead line equipment and accessories. The systems (or part of them) which are rigidly suspended will require special consideration between the cus
26、tomer and the supplier. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
