ShareINFLUENCE OF TRANSVERSE MAGNETIC FIELD ON BREAKDOWN CHARACTERISTICS OF VACUUM, GASEOUS HELIUM AT LOW TEMPERATURE AND LIQUID HELIUM.
Author(s) : HARA M.
Type of article: Article
Summary
THE DIELECTRIC STRENGTH OF COAXIAL CYLINDRICAL GAPS IN VACUUM, GASEOUS HELIUM AT LOW TEMPERATURE OR LIQUID HELIUM HAS BEEN INVESTIGATED UNDER DC STRESSES IN THE PRESENCE OF TRANSVERSE MAGNETIC FIELD. EXPERIMENTAL RESULTS SHOW THAT THE DIELECTRIC STRENGTH IN VACUUM IS LOWERED DRASTICALLY BY THE APPLICATION OF TRANSVERSE MAGNETIC FIELD. THEREFORE, A HIGH VOLTAGE TEST UNDER FULL LOAD CURRENT IS RECOMMENDED TO ENSURE THE SAFE DRIVE OF SUPERCONDUCTING DEVICES WITH VACUUM ELECTRICAL INSULATION. A METHOD FOR IMPROVEMENT OF VACUUM INSULATION PERFORMANCE IS PROPOSED ON THE BASIS OF DISCUSSION ON BREAKDOWN MECHANISM.
