TRANSFORMER Russian patent published in 1997 - IPC

FIELD: electrical engineering. SUBSTANCE: transformer secondary winding is three-dimensional turn that has coaxially arranged current-conducting cylinder 6 and central conductor 3. Transformer secondary (output) winding has two pairs of leads 1, 3 connected to two inductors 7, 8 (load) and two switches capable of shorting out these two pairs of leads thereby shorting out inductors connected to them. This makes it possible to operate into two inductors when switches are open, that is, to treat two parts at a time, or to operate into one inductor, with one switch closed, and to provide for on-line change-over to other inductor in case of changing process or size of treated part. EFFECT: enlarged functional capabilities. 2 cl, 2 dwg
