Title
(EN) THREE-PHASE OVERHEAD ELECTRIC LINE WITH SPLIT PHASES
(FR) LIGNE ELECTRIQUE AERIENNE TRIPHASEE AVEC PHASES DIVISEES
Abstract
(EN)
A three-phase overhead electric line with split phases comprises wires (4) fixed on metallic spacers (5) forming in a plane perpendicular to the axis of the electric line contours of the cross-sections of the split phases (1, 2, 3). The contours of two split phases (1, 2) form circumferences whereas the third split phase (3) consists of two semi-phases the contour of each of them forming a circumference located coaxially to the circumference formed by the contour of another two split phases (1, 2). The minimal distance between the centres of the circumferences formed by the semi-phases is equal to the sum of the radii of those circumferences and provides for the required electric strength between the phases (1, 2) fixed together with the phase (3) through insulators (7) to the supports (8) the elements of which are located outside the space filled by the phases (1, 2, 3) and the air gaps therebetween.

Une ligne electrique aerienne triphasee avec phases divisees comprend des fils (4) fixes sur des elements d'espacement metalliques (5) formant dans un plan perpendiculaire a l'axe de la ligne electrique des contours des sections des phases divisees (1, 2, 3) Les contours de deux phases divisees (1, 2) forment des circonferences tandis que la troisieme phase divisee (3) consiste en deux demi-phases dont chaque contour forme une circonference situee coaxialement par rapport a la circonference formee par le contour d'une autre des deux phases divisees (1, 2). La distance minimum entre les centres des circonferences formees par les demi-phases est egale a la somme des rayons de ces circonferences et assure la resistance electrique requise entre les phases (1, 2) fixees ensemble avec la phase (3) par l'intermediaire d'isolant (7) sur les supports (8) dont les elements sont situes a l'exterieur de l'espace occupe par les phases (1, 2, 3) et les entrefers entre celles-ci.
