SHORT-CIRCUITING PROTECTION DEVICE FOR PERMANENT MAGNET GENERATOR (VERSIONS) Russian patent published in 2013 - IPC H02H7/06 

FIELD: electricity.

SUBSTANCE: device for the first facility contains permanent magnet generator (PMG), the first, second and third output terminals, the first, second and third windings of stator, protection unit, the first, second and third pair of tripping terminals, temperature sensors, at that each winding of stator is divided into the right and left part by protection unit, the first, second and third pair of electric terminals made as semiconductor rectifiers. The claimed device for the second facility PMG, the first, second and third output terminals, the first, second and third windings of stator, protection unit, the first, second and third pair of tripping terminals, temperature sensors, at that each winding of stator is divided into the right and left part by protection unit, the first, second and third pair of electric terminals made as thermal resistors.

EFFECT: increasing operating life of stator winding and decreasing tripping time of PMG windings at short-circuiting due to division of each PMG winding into parts.
