<p>PURPOSE:To reduce the total unit set up width of an equipment by changing the manner of set up so that parallel main bus bars may have a two-deck structure after the passing point of bus bar section lines. CONSTITUTION:A power transmission-and-distribution equipment of double-bus bar system, provided with two systems of bus bar units, is constituted of power receiving lines (I, VIII), power transmitting lines (III, VI), bus bar connecting lines (II, VII) and bus bar section lines (IV, V). Two-line parallel three-phase collective bus bars 1, 2 are arranged parallelly to the surface of the ground. This arrangement of the bus bars is changed in positions X1, X2 of the bus bar section lines (IV, V) that is, plane constitution of upper and lower bus bars 1a, 1b and 2a, 2b is formed.</p> |
