EN IEC 60077-3:2019

Railway applications - Electric equipment for rolling stock - Part 3: Electrotechnical components - Rules for DC circuit-breakers

IEC 60077-3:2019 is available as IEC 60077-3:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60077-3:2019 gives the rules for circuit-breakers, the main contacts of which are connected to DC power and/or auxiliary circuits. The nominal voltage of these circuits does not exceed 3 000 V DC according to IEC 60850. This part of IEC 60077, together with IEC 60077-2, states specifically: a) the characteristics of the circuit-breakers; b) the service conditions with which circuit-breakers complies with reference to: - operation and behaviour in normal service; - operation and behaviour in the case of short circuit - dielectric properties; c) the tests for confirming the compliance of the components with the characteristics under the service conditions and the methods to be adopted for these tests; d) the information to be marked on, or given with, the circuit breaker. This second edition cancels and replaces the first edition, issued in 2001. This edition includes the following main technical changes with regard to the previous edition: - procedure of verification of temperature rise is changed; - air-tightness test as type test, insulation resistance measurement are added.

IEC 60077-3:2019 est disponible sous forme de IEC 60077-3:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60077-3:2019 donne, en complément des règles générales de l'IEC 60077‑2, les règles relatives aux disjoncteurs dont les contacts sont connectés aux circuits à courant continu de traction et/ou aux circuits des auxiliaires. La tension continue nominale de ces circuits n'excède pas 3 000 V CC, conformément à l'IEC 60850. En complément de l'IEC 60077-2, la présente partie de l'IEC 60077 précise particulièrement: a) les caractéristiques des disjoncteurs; b) les conditions de service que les disjoncteurs supportent du point de vue: - du fonctionnement et du comportement en service normal; - du fonctionnement et du comportement en cas de court-circuit; - des propriétés diélectriques; c) les essais de conformité des composants avec les caractéristiques dans les conditions de service ainsi que les méthodes d'essai correspondantes à utiliser; d) les informations à donner ou à marquer sur le disjoncteur. Cette deuxième édition annule et remplace la première édition, parue en 2001. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - modification de la procédure de vérification de l'échauffement; - ajout de l'essai d'étanchéité comme essai de type et de la mesure de la résistance d'isolement.
