Anotation

IEC 60077-2:2017 provides general rules for all electrotechnical components installed in power circuits, auxiliary circuits, control and indicating circuits, etc., on railway rolling stock. The purpose of this document is to adapt the general rules given in IEC 60077-1 to all electrotechnical components for rolling stock, in order to obtain uniformity of requirements and tests for the corresponding range of components. This new edition includes the following main technical changes with regard to the previous edition: - short circuit breaking capacity; - rated short-time withstand current; - critical currents range; - specification of climatic conditions. This standard is to be read in conjunction with IEC 60077-1:2017. L’IEC 60077-2:2017 donne les regles generales applicables a tous les composants electrotechniques installes dans les circuits de puissance, circuits auxiliaires, circuits de commande et de controle, etc., installes sur le materiel roulant ferroviaire. Le present document a pour but dadapter les regles generales donnees dans l’IEC 60077-1 aux composants electrotechniques du materiel roulant afin dharmoniser les exigences et les essais a la gamme de composants correspondante. Cette nouvelle edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - pouvoir de coupure en court-circuit; - courant assigne de courte duree admissible; - plage de courants critiques; - specification des conditions climatiques. Cette norme doit etre lue conjointement avec lIEC 60077-1:2017.
