Method and apparatus for mounting a large capacitor

摘要

A mounting arrangement for a capacitor package is disclosed. The capacitor package is suitable for use in electric drive traction applications that are subjected to high vibration. Such a capacitor package is relatively large and requires a unique mounting arrangement in order to account for a large mass and high vibration environment. The mounting arrangement provides a clamp load plane that is near the center of mass of the capacitor package.

主权项

1. A capacitor package having a length, width, and height, and a center of mass comprising:
a first and second generally planar oppositely facing surface having said width and height; the first and second surfaces having a mounting protrusion configured to form a portion of a bolted joint and having a first protrusion surface and a second protrusion surface separated by a thickness; and wherein the first protrusion surface of each mounting protrusion forms a clamp load plane that passes within approximately 10% of the height of a parallel plane containing the center of mass, said mounting protrusion includes two through-holes that extend from the first protrusion surface to the second protrusion surface and material savers located between said through-holes.
