Multi-neutral electrical busway

Canalisation multiple de barres omnibus neutres

Abstract

A three-phase electrical power distribution busway having neutral busbars configured to have a higher current carrying capacity than each of the phase busbars of the busway is described. The neutral busbars have a combined cross-sectional area which is greater than the cross-sectional area of each of the phase busbars. The neutral busbars have a rectangular cross section configured to reduce the skin effect and reduce ohmic heating caused by increased neutral busbar currents resulting from non-linear loads.
Canalisation multiple de barre omnibus d'acheminement de courant électrique triphasé comportant des barres omnibus neutres conçues pour avoir une capacité d'acheminement du courant plus élevée que chacune des barres de phase de la canalisation. Les barres neutres présentent une section transversale combinée supérieure à la section transversale de chacune des barres de phase. Les barres neutres présentent une section transversale rectangulaire, étudiée pour réduire l'effet de surface et l'échauffement par effet Joule consécutifs à un accroissement des courants dans les barres neutres sous l'effet de charges non linéaires.
