EN 50122-1:2011

Railway applications - Fixed installations - Electrical safety, earthing and the return circuit - Part 1: Protective provisions against electric shock

This European Standard specifies requirements for the protective provisions relating to electrical safety in fixed installations associated with a.c. and/or d.c. traction systems and to any installations that can be endangered by the traction power supply system. It also applies to all aspects of fixed installations that are necessary to ensure electrical safety during maintenance work within electric traction systems. This European Standard applies to all new lines and to all major revisions to existing lines for the following electric traction systems: a) railways; b) guided mass transport systems such as 1) tramways, 2) elevated and underground railways, 3) mountain railways, 4) trolleybus systems, and 5) magnetically levitated systems, which use a contact line system, c) material transportation systems. This European Standard does not apply to: d) mine traction systems in underground mines; e) cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly or via transformers from the contact line system and are not endangered by the traction power supply system; f) suspended cable cars; g) funicular railways. This European Standard does not specify working rules for maintenance.

Železniške naprave - Stabilne naprave električne vleke - Električna varnost, ozemljitev in povezovanje - 1. del: Zaščitni ukrepi proti električnemu udaru

Ta evropski standard določa zahteve za zaščitne ukrepe v zvezi z električno varnostjo pri stabilnih napravah električne vleke na izmenični in/ali enosmerni tok in pri vseh inštalacijah, ki jih lahko ogroža napajanje sistema za vleko. Velja tudi za vse vidike stabilnih naprav, potrebnih za zagotavljanje električne varnosti med vzdrževalnim delom v električnih sistemih vleke. Ta evropski standard velja za vse nove vode in za vse večje prenove obstoječih vodov za naslednje električne sisteme vleke: a) železnice; b) vodene sisteme množičnega prevoza, kot so 1) tramvajske proge, 2) nadzemne in podzemne železnice, 3) gorske železnice, 4) trolejbusni sistemi in 5) sistemi z magnetnim lebdenjem, ki uporabljajo sistem voznih vodov, c) sisteme za prevoz materiala. Ta evropski standard ne velja za: d) rudniške vlečne sisteme v podzemnih rudnikih; e) žerjave, prenosne platforme in podobno opremo za prevoz po tirih, začasne strukture (npr. razstavne strukture), če niso napajane neposredno ali preko transformatorjev s sistema voznih vodov in jih ne ogroža napajanje sistema za vleko; f) viseče kabinske žičnice; g) vzpenjače. Ta evropski standard ne določa delovnih pravil za vzdrževanje.
