Title:
ELECTROMAGNETIC PUMP COMPENSATION POWER SUPPLY APPARATUS AND ELECTROMAGNETIC PUMP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/001768
Kind Code:
A1
Abstract:
Provided, in parallel to an electromagnetic pump in a power supply system, is an electromagnetic pump compensation power supply mechanism (10) that will perform a power-factor correction function as a synchronous machine upon normal operation of a plant. The electromagnetic pump compensation power supply mechanism (10) is provided with an exciter stator permanent magnet apparatus (45) that can switch an exciter between a non-excited state and an excited state. The exciter stator permanent magnet apparatus (45) comprises exciter stator permanent magnets (15a), springs (16) that apply force to the exciter stator permanent magnets (15a) towards positions facing an exciter rotor winding (15b), and electromagnetic solenoids (20) that make the exciter stator permanent magnets (15a) move to positions not facing the exciter rotor winding (15b), in resistance to the force applied by the springs (16).
