Abstract

La présente invention porte sur un procédé de distribution d'énergie sans interruption lors du remplacement d'une ligne électrique connectée à chacun des poteaux électriques et de la modification de l'installation de celle-ci, et pendant une construction pour le changement d'emplacement de passe-système. Plus particulièrement, un remplacement de câble triphasé ininterrompu est réalisé par l'intermédiaire d'une séparation d'électricité séquentielle et d'une connexion de chaque phase, par utilisation d'un dispositif de modification de ligne électrique qui étend l'une des trois phases d'un câble de dérivation sur le sol ou sur un poteau électrique, et les poteaux électriques peuvent être remplacés et d'une construction pour la modification de l'emplacement d'installation des poteaux électriques à l'aide du même procédé. En conséquence, une construction efficace et raisonnable pour une distribution d'énergie ininterrompue peut être obtenue dans des endroits, tels que des centres villes dans des villes métropolitaines, où la sécurité des piétons est menacée en raison d'une proximité étroite avec des poteaux électriques, et où différents obstacles, tels qu'un contact avec des bâtiments, existent. En outre, en fonction des compétences et des préférences de l'électricien spécialisé dans la distribution d'énergie ininterrompue, le procédé de distribution d'énergie ininterrompue pourrait être sélectionné parmi une large gamme et appliqué à une large gamme, permettant ainsi d'étendre la zone de travail de distribution d'énergie ininterrompue, d'améliorer la sécurité en favorisant une stabilité psychologique du travailleur, et de réduire efficacement les pannes d'électricité et d'améliorer la qualité énergétique pendant une construction par extension de la zone de construction.
