Magnetic Circuits.
The main activities area of our Company is production of magnetic circuits for transformers. Our equipment enables to manufacture magnetic circuits of any construction, dimensions and type.
Stranded strap magnetic circuits are characterized by possibility of use of different thickness material (up to a few micrometers), enabling to apply them for transformers at increased frequencies, by better use of material magnetic properties (especially of cold-rolled steel) than plate magnetic circuits, by slightly increased losses, availability of air gap in butts and lower production cost.
Sell-type, core-type and ring-type (toroidal) magnetic circuits are distinguished between magnetic circuits according to construction.
The following types of stranded (strap), shell-type and core-type magnetic circuits are produced:
- ØË – Ø-shaped strap magnetic circuit
- ØËÌ – Ø-shaped strap magnetic circuit with decreased ratio l1 /l
- ØËÎ – Ø-shaped strap magnetic circuit with increased aperture
- ØËÏ – Ø-shaped strap magnetic circuit with increased ratio B/l
- ÏË – core-type Ï- shaped strap magnetic circuit
- ÏËÌ – Ï-shaped strap magnetic circuit with decreased ratio l1 /l
All magnetic circuits of these types consist of two identical parts.
It is recommended to use magnetic circuits of ØË and ØËÌ types in transformers of the lowest weight at rated transformer power not more than 100 W (ØË type – at frequency of 400 Hz, ØËÌ type – at frequency of 50 Hz), magnetic circuits of ØËÎ type – in low-voltage transformers at frequency from 1,000 to 5,000 Hz and in high-voltage at frequency from 50 to 5,000 Hz, magnetic circuits of ÏË type – in low-voltage transformers at frequency from 50 to 400 Hz and at rated power more than 500 W and also in chokes.
