CONTROLLED ELECTRIC REACTOR Russian patent published in 2019 - IPC H01F21/08 H01F29/14 

FIELD: electrical engineering.

SUBSTANCE: controlled electric reactor belongs to the field of electrical engineering and can be used as a shunt reactor to regulate voltage and reactive power in high-voltage power lines. Reactor contains an electronic control system and an electromagnetic part, including the coiled sections of the power winding and the control winding in each phase of the reactor, as well as a core magnetic core, the rods of which are made of elements arranged in series along the height and divided into two parallel parts, respectively, internal and external. Nonmagnetic gap is made in the inner part and the outer part of the rod element, the wires turns of the power winding sections cover the cross section of the rod entirely, and the wires turns of the control winding sections – partially. Number of sections of the control winding is paired, the ends of adjacent sections in the control winding are connected in parallel, the direction of winding in them is opposite, parallel parts of the reactor core element are made in the form of the disks from the electrical steel plates radially laminated around the perimeter, separated from other rod elements by nonmagnetic gaps, the control winding sections are located inside the external disk, power winding sections are located outside the external drive, the electronic control system is designed as a controlled constant voltage source, its output terminals are connected to the ends of a pair of control winding sections.

EFFECT: possibility of controlled low-voltage magnetization of local elements of the magnetic core is provided.
