Systems and methods for isolating a conduit enclosure for an explosion proof motor

摘要

An enclosure system for isolating a conduit enclosure for an explosion proof motor is provided. The enclosure system includes a stator enclosure defining a first enclosure opening. The enclosure system also includes a conduit enclosure coupled to the stator enclosure. The conduit enclosure comprises at least one side wall, a rear wall coupled to the side wall, and an interior cavity. The rear wall defines a first entry port having a first volume. The enclosure system further includes at least one electrical lead. The at least one electrical lead extends through the first enclosure opening, through the first entry port, and into the interior cavity. The at least one electrical lead occupies a portion of the first volume and leaves a remaining volume. The enclosure system also includes sealing compound. The sealing compound is coupled with the first entry port such that substantially all of the remaining volume is occupied.

1. An enclosure system comprising:
a stator enclosure defining a first enclosure opening; a conduit enclosure coupled to said stator enclosure, said conduit enclosure comprising at least one side wall, a rear wall coupled to said side wall, an interior cavity, and a support feature, said rear wall defining a first entry port having a first volume, said first entry port comprising two semi-circular voids, said support feature comprising a support bar coupled to said rear wall and extending across said first entry port, said support bar disposed between and defining said two semi-circular voids; at least one electrical lead extending from said stator enclosure through said first enclosure opening, through said first entry port, and into said interior cavity, said at least one electrical lead occupying a portion of said first volume and leaving a remaining volume; and sealing compound coupled with said first entry port such that substantially all of the remaining volume is occupied, wherein said support feature mechanically supports said sealing compound to withstand pressure from an internal explosion within at least one of said conduit enclosure and said stator enclosure.
