Arc suppression unit for compensation of capacitive currents earth fault

摘要

Quenching unit consisting of the neutral forming transformer and quenching the reactor, placed in a single housing comprising chetyrehsterzhnevoy magnetic circuit, at 3 terminals of which are arranged three-phase neutral forming transformer windings connected according to the "zigzag", on the 4th rod having air gaps located reactor winding with terminals connected to the neutral of the transformer and the ground bus, characterized in that the rods, upper and lower yokes of the magnetic neutral forming transformer and spatially arranged symmetrically at an angle of 120 °, the magnetic circuit of the reactor shaft is located in the center of the transformer magnetic system.
