Railway applications - Rolling stock - Electric equipment in trolley buses - Safety requirements and current collection systems
This European Standard applies to electrical systems on board of vehicles of the type trolleybus, as defined in 3.1, fed with a nominal line voltage (Un) between 600 V d.c. and 750 V d.c. This European Standard defines the requirements and constructional hints, especially to avoid electrical danger to the public and to staff. Where special requirements are existing for trolleybuses, hints are given for mechanical and functional safety as well as for protection against fire. This European Standard covers vehicles intended for public transport of persons. This Standard applies to: - trolleybuses, - buses with current rail for guidance in the road surface, - guided buses with bipolar roof current collector. This European Standard does not apply to: a) electric driven vehicles with only internal power supply: 1) hybrid vehicles, 2) diesel - electric vehicles, 3) fuel - cell vehicles, 4) battery vehicles, b) vehicles with safe protective bonding: 1) rubber tyred commuter trains, 2) guided buses with supply by a separate current rail, 3) rail guided buses with unipolar roof current collector, c) vehicles operated outside publicly accessible areas: 1) electric driven lorries on motorways. Guidance and current rails are special solutions and at this time are not under standardization like trolleybus current collectors and overhead contact lines (OCL). It refers mainly to earthed networks, but reference is made also to galvanically insulated networks. Annex A is related to detailed design features for trolleybuses. Annexes B and C are related to the connection systems. The detailed scope of these annexes is given in Annex B.

Cette Norme européenne s’applique aux systèmes électriques à bord des véhicules de type trolleybus, définis en 1.3.1, alimentés par une tension de ligne (Un) comprise entre 600 V c.c. et 750 V c.c. Cette Norme européenne définit les exigences et les recommandations de construction, particulièrement pour éviter les dangers de type électrique pour le public et le personnel. Lorsque les trolleybus sont soumis à des exigences particulières, des recommandations sont dispensées, concernant aussi bien la sécurité mécanique et fonctionnelle que la protection contre les incendies. Cette norme Européenne concerne les équipements de transport public. Elle s’applique aux : - trolleybus, - autobus équipés d’un rail de traction électrique pour le guidage sur la surface de roulement, - autobus guidés par un système de captage de courant bipolaire sur la toiture. Cette norme ne s’applique pas aux : - véhicules électriques équipés d’une alimentation électrique interne, - véhicules hybrides, - véhicules diesel - électriques, - véhicules à pile à combustible, - véhicules à batterie, - véhicules équipés d’une liaison de protection sécurisée, - trains de banlieue à pneumatique, - autobus guidés alimentés par un rail d’alimentation en courant, - autobus guidés par rail équipés d’un système de captage de courant unipolaire sur la toiture, - véhicules fonctionnant hors des zones accessibles au public, - poids lourds électriques sur autoroute. Le guidage et les rails de courant sont des solutions spécifiques et ne sont pas soumis à la normalisation comme les systèmes de captage de courant et les lignes aériennes de contact (LAC) des trolleybus. Elle traite principalement des réseaux mis à la terre, mais traite également des réseaux isolés galvaniquement. L’Annexe A spécifie les éléments de conception détaillés des trolleybus. Les Annexes B et C traitent des systèmes de connexion. Le domaine d'application de ces Annexes est détaillé dans l’Annexe B.
Železniške naprave - Vozna sredstva - Električna oprema v trolejbusih - Varnostne zahteve in povezovalni sistemi
Ta evropski standard se uporablja za električne sisteme v trolejbusih, ki so opredeljeni v točki 1.3.1 in se napajajo z nazivno napetostjo (Un) med 600 V in 750 V enosmerne napetosti.
Ta evropski standard opredeljuje zahteve in napotke za načrtovanje ter zlasti za preprečevanje kakršne koli nevarnosti električnega toka za javnost in osebje. Pri posebnih zahtevah za trolejbuse so podani napotki za mehansko in funkcionalno varnost ter protipožarno zaščito.
Ta evropski standard zajema vozila, namenjena javnemu prevozu oseb. Ta evropski standard se uporablja za:
– trolejbuse,
– avtobuse s tokovnimi tračnicami za vodenje na površini droga,
– vodene avtobuse z bipolarnim strešnim tokovnim odjemnikom.
Ta standard se ne uporablja za:
– električna vozila z notranjim električnim napajanjem,
– hibridna vozila,
– dizelsko-električna vozila,
– vozila na gorivne celice,
– akumulatorska vozila,
– vozila z varnimi zaščitnimi vodniki,
– potniške vlake z gumijastimi pnevmatikami,
– vodene avtobuse, ki se napajajo prek ločene tokovne tračnice,
– tračno vodene avtobuse z monopolarnim strešnim tokovnim odjemnikom,
– vozila, ki obratujejo zunaj javno dostopnih območij,
– električne tovornjake na cestah, rezerviranih za motorna vozila.
Vodilne in tokovne tračnice so posebne rešitve, ki tokrat niso predmet standardizacije, kot so tokovni odjemniki na trolejbusih in kontaktni vodniki (OCL).
Standard se nanaša predvsem na ozemljena omrežja, vendar se v njem pojavijo tudi sklici na galvansko izolirana omrežja.
Dodatek A se nanaša na podrobne oblikovne značilnosti trolejbusov.
Dodatka B in C se nanašata na priključitvene sisteme. Podrobnosti o področju uporabe teh dodatkov so navedene v dodatku B.
