INDUCTANCE COIL OF CURRENT-LIMITING REACTOR Russian patent published in 2013 - IPC H01F27/28 H01F27/30 

FIELD: electrical engineering.

SUBSTANCE: inductance coil is cylindrically-shaped; it has turns wound by km parallel wires which beginnings are located at its one butt-end and ends at the other one. Parallel wires are divided into m groups forming n parts in a group; each of them is located at a certain height level and occupies m cocentres placed at least at one main frame. At least two parts forming one group are located in different cocentres. There are (n-1) of frames introduced additionally, placed at the coil height and rigidly interconnected and connected to the main frame. So each of n parts is placed at the respective frame. Parallel wires are joined in groups so that at least two groups of m groups are symmetrical in relation to the average line at the coil height where m is an integer number ≥4; n - integer number ≥2; k=1 - number of parallel wires in a group.

EFFECT: improving the use of technology due to widening of the assortment of process equipment suitable for manufacturing and reducing labour intensity at relatively low manufacturing costs comparable with manufacturing costs for inductance coils of current-limiting reactors for voltage of 10-35 kV die to use of analogical insulation of winding wire.
