Arc suppression unit for compensation of capacitive currents earth fault

摘要

Field of use relates to electrical engineering, namely to a device for compensation of capacitive currents in electrical networks 6-35 kV. Summary of the utility model: quenching unit comprises a neutral forming transformer and the reactor placed in the same housing. Magnetic quenching unit is formed on the rods 4: 3 on a spatial rods disposed at 120 ° relative to each other, are installed working neutral forming transformer winding connected on a "zigzag"; at the 4th rod yoke having air gaps and installed in the center of a three-phase magnetic system has a working winding terminals which are connected to three-phase transformer neutral and ground bus. The achieved technical result: reduction in the active power losses, material capacity and overall dimensions, increase the reliability of operation and simplify maintenance.
