ELECTROMAGNETIC SYSTEM FOR MAGNETOCALORIC REFRIGERATOR

摘要

Usage: in the technique of strong magnetic fields. SUBSTANCE: electromagnetic system (EMC) for a magnetocaloric refrigerator comprises a magnetic system consisting of n superconducting solenoids and an energy supply system consisting of n controlled current sources with control circuits. The EMC comprises a timing circuit coupled to current source control circuits. The number n of solenoids and controlled current sources n is determined by the formula n E (Tu / tH), where Tc is the time of the magnetization reversal cycle of the solenoids; tH is the time of their magnetization; E is the integer part of the number. The synchronization circuit provides synchronization of the moments of magnetization and demagnetization of the solenoids, which reduces the interaction of the magnetic system with the supply network, reduces the installed power of the equipment. 3 s.p. f-ly, 7 ill.
