Feasibility of Remote Control and Development of Remote Control Devices and Sensors - Volume 7 - Feasibility Study of the Application of Solid State Motor Controllers to Underground Mining Machines.
NTIS: PB/224-256 Available for Reference At Bureau Libraries :72 pages
This work was directed toward a general study of solid-state control devices available, their potential use on electrical machinery used in underground mines, and the general effect that the use of solid- state devices might have on the safe operation of machines. The underground mine environment presents rather severe physical and electrical stresses to machinery. Silicon-controlled rectifiers (scr) that meet mine requirements are available. Although scr initial costs appear to be higher than costs for electromechanical contractors, savings should result from reduced maintenance requirements, safer operation, higher reliability, elimination of mechanical transmissions, elimination of rectifier centers, and standardization on ac power.
