SWITCHGEAR INVESTIGATIONS FOR A 400-HP C.C. SUPERCONDUCTIVE PROPULSION SYSTEM

The report describes candidate switchgear for the electrical power circuit of a 400-horsepower ship propulsion system utilizing superconducting direct-current machinery. The switchgear comprises an intermittent duty rheostat, five single-pole single-throw contactors, current limiting fuses, and a controller which provides the proper sequencing of the various switchgear components for shipboard propulsion system control. The salient features of propulsion systems employing acyclic motors and generators are discussed, and the characteristics of several types of switchgear are examined to indicate the reasons for the selection of switchgear to be used in the 400-horsepower propulsion system. Detail designs for the fluid- displacement, liquid-metal contactor, the intermittent duty rheostat, and the controller will appear in future reports.
