Electrical shunt reactor

Claim 1

A SHUNT REACTOR HAVING A VOLTAGE RATING OF THE ORDER OF AT LEAST 200 KILOVOLTS COMPRISING, DUPLICATE SIDE-BY-SIDE CYLINDRICAL CONDUCTIVE COILS WITH THEIR AXES PARALLEL, SAID COILS EACH HAVING A CENTRAL WINDOW CORRESPONDING IN CROSSSECTIONAL EXTENT TO THE INNER DIAMETER OF SAID COILS AND HAVING OPPOSITE END FACES, SOLID CORES FORMED OF HIGH RELUCTANCE PARAMAGNETIC MATERIAL STRUCTURALLY RIGID IN COMPRESSION AND DISPOSED IN SAID WINDOWS, SAID CORES HAVING THEIR ENDS FLUSH WITH THE END FACES OF SAID COILS, AND A PAIR OF ELECTRICALLY CONDUCTIVE LAMINATED YOKE MEMBERS OF LOW RELUCTANCE MAGNETIC MATERIAL POSITIONED ACROSS THE ADJACENT END FACES OF SAID COILS AND CORES AT OPPOSITE ENDS THEREOF RESPECTIVELY WITH THEIR LAMINATIONS EDGEWISE TO SAID END FACES OF SAID COILS BEING AT LEAST EQUAL TO THE OUTTHE END FACES OF SAID COILS BEING AT LEAST EQUAL TO THE OUTSIDE DIAMETER OF SAID COILS, SAID COILS HAVING INTERCONNECTED CENTER TAPS COMPRISING THE LINE TERMINAL OF SAID REACTOR AND HAVING THEIR AXIALLY OPPOSITE ENDS ELECTRICALLY CONNECTED TO SAID YOKE MEMBERS, SAID YOKE MEMBERS BEING ELECTRICALLY CONNECTED TOGETHER AND TO GOUND THEREBY TO PROVIDE FOUR ELECTRICALLY PARALLEL CURRENT PATHS THROUGH SAID REACTOR, THE TURNS OF EACH COIL BEING OPPOSITELY WOUND BETWEEN ITS CENTER TAP AND ITS AXIALLY OPPOSITE ENDS SO THAT SAID FOUR CURRENT PATHS PRODUCE ADDITIVE MAGNETOMOTIVE FORCES IN A COMMON MAGNETIC CIRCUIT CONSISTING OF SAID COILS AND YOKE MEMBERS MAGNETICALLY IN SERIES, SAID YOKE MEMBERS ACTING AS MAGNETIC AND ELECTROSTATIC SHIELDS FOR SAID COILS AND SAID CORES ALONE SERVING AS MECHANICAL SEPARATORS FOR SAID YOKE MEMBERS.
