IEC 62486:2017 pdf download.Railway applications – Current collection systems – Technical criteria for the interaction between pantograph and overhead contactline (to achieve free access)
1 Scope
This document specifies requirements for the interaction between pantographs and overhead contact lines, to achieve interoperability. NOTE These requirements are defined for a limited number of pantograph types, referred to as ‘interoperable pantograph’, together with the geometry and characteristics of compatible overhead contact lines. This document describes parameters and values for all planned lines and future lines.

3.1 arcing flow of current through an air gap between a contact strip and a contact wire usually indicated by the emission of intense light 3.2 automatic dropping device device that lowers the pantograph in the event of pantograph head failure or damage of the pantograph head [SOURCE: IEC 60494-1 :201 3, 3.2.1 9] 3.3 contact force vertical force applied by the pantograph to the overhead contact line Note 1 to entry: The contact force is the sum of forces of all contact points. 3.4 contact point point of the mechanical contact between a contact strip and a contact wire 3.5 contact wire height distance from the top of the rail (or road surface for overhead contact line system for trolleybus applications) to the lower face of the contact wire, measured perpendicular to the track Note 1 to entry: The contact wire height is measured perpendicular to the track or road surface. 3.6 continuous pantograph head profile pantograph head with collector strips and horns suspended in one piece 3.7 encroachment of the pantograph head above the contact plane perpendicular distance from the contact plane to the highest point of the pantograph head. The contact plane is the plane parallel to base frame of pantograph at the contact point Note 1 to entry: Additional information is given in EN 1 5273-1 :201 3, Figure 46. 3.8 maximum contact wire height maximum value of the contact wire height above rail level occurring in any possible case during the lifetime of the overhead contact line 3.9 maximum design contact wire height maximum theoretical contact wire height not including tolerances and uplift, which the pantograph is required to reach 3.1 0 maximum width of pantograph head maximum distance measured along the axis of the track between the outer edges of the contact strips 3.1 1 mean contact force F m statistical mean value of the contact force
