High efficiency paired phases busway system
View Patent ↗A paired phase electrical power distribution bus way system wherein the three phase paired conductors are surrounded and encapsulated by the neutral conductor and packed all together with the housing as a company element to obtain equal separation between the neutral bus bar assembly and the paired phase conductors. The neutral conductor or bus bar assembly consists of two covers that sandwich the three pairs of phase conductors and the insulator layers to achieve minimum and equal distance between them and to reduce and balance the impedance between the neutral and the paired conductors. The housing compresses each pair through the neutral conductor and insulation layer to maintain contact between the conductors, the neutral, and the housing to get efficient heat conduction to the outside.
1. A three-phase bus duct section comprising:
A) first, second and third bus bar pairs; each of said pairs including first and second flat bar conductors kept at a parallel and spaced apart relationship with respect to each other and said first and second flat bar conductors wherein said conductors are connected to achieve paired phase conductor effect, respectively;
B) neutral bus bar assembly having cooperative dimensions to encapsulate said first, second, and third pairs without being electrically connected; and
C) housing means supporting said neutral bus bar assembly.
2. The bus duct section set forth in claim 1 wherein a separation between said neutral bus bar assembly and said first, second, and third bus bar pairs is substantially the same.
3. The bus duct section set forth in claim 2 wherein said first and second flat bar conductors have opposing facing surfaces separated by an electrical insulator.
4. The bus duct section set forth in claim 3 wherein said housing means is grounded.
5. The bus duct section set forth in claim 4 wherein said neutral bus bar assembly transmits heat from said flat bar conductors to said housing means so that said heat is dissipated.
6. The bus duct section set forth in claim 5 wherein the encapsulation of said first, second, and third pairs results in a mechanically stable structure to withstand the effects of short circuits.
