Abstract
A motor control system includes a single, multicompartment enclosure mounted on a skid. The enclosure contains a transformer circuit and a motor controller circuit interconnected so that only external connections to a power source and a load are needed. When the circuits are energized, access to high voltage motor control components and to field replaceable fuses and output selection switches is prevented by a double interlocking mechanism which operates in conjunction with energizing and de-energizing the transformer.
The transformer of the transformer circuit includes a tertiary winding disposed radially between a primary winding and a secondary winding. The winding filters electrostatically coupled transients. A conventional electrostatic shield is also used so that the transformer is doubly shielded to electrostatic transients. The tertiary winding is connected to one or more capacitors to filter magnetically coupled transients. A current limiting fuse, a load sensing fuse and a primary make/break switch are connected in electrical series to the primary winding. Methods for energizing or operating a motor utilizing the primary switch and the load sensing fuse are also disclosed.
