What is BS EN 50206-2 - Pantographs for metros and light rail vehicles about?
BS EN 50206 is a European standard that discusses the pantographs used in rolling stock for railway applications. BS EN 50206-2 is the second part of a multi-part series that outlines the general assembly characteristics that are to be applied to pantographs to enable current collection from the overhead line equipment.
BS EN 50206-2 defines the tests the pantographs must perform, excluding insulators.
BS EN 50206-2 relates to conventional suspended overhead line equipment and accessories. The systems (or part of them) which are rigidly suspended can require special consideration between the customer and the supplier.
Note 1: BS EN 50206-2 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 upon between customer and supplier, insulation coordination according to EN 50124-1 may be used.
Note 2: BS EN 50206-2 does not apply to pantographs used on mainline vehicles. These pantographs are considered in EN 50206-1.
Who is BS EN 50206-2 - Pantographs for metros and light rail vehicles for?
BS EN 50206-2 on pantographs for metros and light rail vehicles is useful for:
- Pantograph manufacturers
- Test centres
- Regulatory authorities
Why should you use BS EN 50206-2 - Pantographs for metros and light rail vehicles?
The electrical power supply of a tractive unit is achieved by the collection of current from the contact wire using one or more pantograph(s), installed on the traction unit or the vehicle. The contact strip of the pantograph which slides along the contact wire facilitates the transmission of power.
BS EN 50206-2 guideline assists you with technical requirements on the extension of the pantographs, electric values, static contact force tolerances, transverse rigidity, collector head, operating system, automatic dropping device (A.D.D.), protection against corrosion, pantograph mass, and force on the roof for pantographs used in metros and light rail vehicles.
BS EN 50206-2 guides on operating tests, endurance tests, resistance to shocks (supplementary type test), transverse rigidity test, air tightness tests, measurement of degrees of freedom of collector’s head (routine test), current collection tests (combined test) and heating tests for pantographs used in metros and light rail vehicles. This assists in enhancing the efficacy of pantographs to prolong their life.
BS EN 50206-2 also guides regarding inspection plans, reliability, and maintenance of pantographs used in metros and light rail vehicles.
With obedience and compliance to BS EN 50206-2, you can standardise the quality and performance of pantographs used in metros and light rail vehicles.
