Abstract
A low inductance bus bar arrangement suitable for industrial voltage levels, and for power applications contains two or more elongate electrical conducting bars having rounded edges. Strips of dielectric insulating material are located between two of the elongate electrical conducting bars. The conducting bars are oriented in substantially parallel relationship to one another with the dielectric insulating material having a height of the cross-section thereof substantially greater than the height of the cross-section of the conducting bars. The bus bar arrangement also provides low inductance to the connecting devices.
Claims25

- two or more elongate electrical conducting bars having rounded edges thereon;
- one or more strips of dielectric insulating material, each strip of dielectric insulating material being located between two of said elongate electrical conducting bars, said strips of dielectric insulating material having a height and length being greater than the height and length, respectively of said elongate electrical conducting bars.
A low inductance bus bar arrangement comprising:
- two or more elongate electrical conducting bars having rounded edges thereon;
- one or more strips of dielectric insulating material, each strip of dielectric insulating material being located between two of said elongate electrical conducting bars, said strips of dielectric insulating material having a height and length being greater than the height of said elongate electrical conducting bars;
- and
- apertures extending through the electrical conducting bars and strips of dielectric insulating material wherein said conducting bars and strips are held together using a fastening means extending through the apertures.
A low inductance bus bar arrangement comprising:
- two or more elongate electrical conducting bars having rounded edges thereon and having their height substantially vertically oriented;
- one or more strips of dielectric insulating material, each strip of dielectric insulating material being located between two of said elongate electrical conducting bars, said strips of dielectric insulating material having a height and length being greater than the height of said elongate electrical conducting bars;
- and
- a connecting foot affixed to each of said conducting bars by a fastener inserted through an aperture within a conducting bar, said fastener having a head being recessed within the aperture of the conducting bar and protruding through said aperture and through a coaxial aperture within the connecting foot.
A low inductance bus bar assembly comprising:
