Integrated air cooling and arc resistant system for medium voltage drive

An integrated air cooling and arc resistant system for a voltage drive, the system comprising:

• a cabinet including a lower baffle and an upper baffle, the cabinet including an upper portion and a lower portion;
• a plurality of first power cells disposed in the cabinet;
• a plurality of second power cells disposed in the cabinet;
• a central chimney vertically disposed in a space between the plurality of first power cells and the plurality of second power cells;
• a transformer clamped between upper clamps and lower clamps while disposed in the cabinet and being underneath the plurality of first power cells and the plurality of second power cells, the transformer having a top end and a bottom end;
• and
• a vertical plenum disposed in a back of the cabinet, the vertical plenum configured to flow cool air passing from the plurality of first power cells and the plurality of second power cells towards the bottom end of the transformer,
• wherein the lower baffle is configured to prevent warm air from flowing from the transformer to the plurality of first power cells and the plurality of second power cells, and
• wherein the upper baffle is configured to force the warm air from the transformer and the cool air from the transformer into the central chimney.
