Electrical reactor

Claim 1

A SHUNT REACTOR HAVING A VOLTAGE RATING OF THE ORDER OF AT LEAST 200 KILOVOLTS FOR CONNECTION ACROSS AN ELECTRIC CIRCUIT COMPRISING, IN COMBINATION, DUPLICATE CIRCULAR CROSS-SECTION CYLINDRICAL CONDUCTIVE COILS MOUNTED WITH THEIR AXES IN PARALLEL SPACED APART RELATION AND THEIR ADJACENT PAIRS OF END FACES IN COPLANAR RELATION, EACH SAID COIL COMPRISING A PLURALITY OF SERIALLY CONNECTED COAXIAL PANCAKE SECTIONS AND BEING PROVIDED WITH OPPOSITE END TERMINALS, SEPARATE MAGNETIC STEEL YOKE MEMBERS BRIDGED ACROSS EACH COPLANAR PAIR OF SAID END FACES, EACH SAID YOKE MEMBER BEING AT LEAST AS WIDE AS THE OUTSIDE DIAMETER OF ONE OF SAID COILS AND AT LEAST AS LONG AS THE AXIAL SPACING THEREBETWEEN PLUS A DIAMETER OF ONE OF SAID COILS, SAID COILS BEING OPPOSITELY WOUND AND ELECTRICALLY CONNECTED IN PARALLEL CIRCUIT RELATION BETWEEN OPPOSITE PAIRS OF SAID END TERMINALS, MEANS CONNE CTING SAID OPPOSITE PAIRS OF END TERMINALS RESPECTIVELY TO SAID SEPARATE YOKE MEMBERS FOR ELECTRICAL OPERATION OF SAID YOKE MEMBERS AT OPPOSITE LINE VOLTAGE OF SAID ELECTRIC CIRCUIT, AND SEPARATE STRUCTURAL COLUMNS OF COMPRESSIVELY STRONG PARAMAGNETIC ELECTRICAL INSULATING MATERIAL IN THE WINDOWS OF SAID COILS FOR BEARING THE ATTRACTIVE MAGNETIC FORCE BETWEEN SAID YOKE MEMBERS AND KEEPING IT FROM BEING APPLIED TO SAID COILS, SAID YOKE MEMBERS MAGNETICALLY SHIELDING SAID COILS IN THE SENSE THAT THEY PREVENT CROSS AXIAL DIRECTION FLUX IN SAID COILS NEAR THEIR ENDS WHICH WOULD PRODUCE HIGH AXIAL ELECTROMAGNETIC COMPRESSIVE FORCES IN SAID COILS AND CREATE VIBRATION OF DESTRUCTIVE AMPLITUDE, SAID YOKE MEMBERS ALSO ELECTROSTATICALLY SHIELDING SAID COILS IN THE SENSE THAT THEIR CAPACITANCES FAVORABLY INFLUENCE THE DISTRIBUTION OF VOLTAGE IN SAID COILS UNDER IMPULSE CONDITIONS.
