Guidance for installation procedures and tolerances of hydroelectric machines - Part 5: Bulb turbines and generators
IEC 63132-5:2023 to establish, in a general way, suitable procedures and tolerances for the installation of hydroelectric turbines and generators. This guide presents a typical assembly. It should be recognized that there are many possible ways to assemble a unit. The size of the machines, design of the machines, layout of the powerhouse and delivery schedule of the components are some of the elements that could result in additional steps, the elimination of some steps and/or assembly sequences.
Lignes directrices des procédures et tolérances d’installation des machines hydroélectriques - Partie 5: Turbines et alternateurs de type bulbe
IEC 63132-5:2023 doit établir, de manière générale, des procédures et des tolérances appropriées pour l’installation de turbines et de générateurs hydroélectriques. Ce guide présente un assemblage typique. Il faut reconnaître qu’il existe de nombreuses façons possibles d’assembler une unité. La taille des machines, la conception des machines, la disposition de la centrale et le calendrier de livraison des composants sont quelques-uns des éléments qui pourraient entraîner des étapes supplémentaires, l’élimination de certaines étapes et / ou des séquences d’assemblage.
