Power transformers, TS-270, ST-270, were produced on splitting, core cores of the O-shaped shape made of E-320 steel tape, a cross-section of 25x50 mm, and were intended for installation in color lamps, or into lamp-semiconductor TVs. In TCA-270 transformers, the core is slightly smaller and has a cross section of 25x45 mm.
Rated power of transformers - 270 watts. Connecting the primary winding of transformers to the 220 volt network, is made to the conclusions 1 and 1, and at the same time conclusions 2 and 2 conclusions.
The primary winding in these transformers of the last editions can be performed only by 220 volts (no output 3).
It must be borne in mind that the motch data given here may differ on your transformers you have Due to the changes in the factors of manufacturers, time stages and other conditions and should be taken only as the basis. If necessary, determine a more accurate number of turns of the windings of the available transformer, wrap an additional winding with a known amount of turns, measure the voltage on it and calculate your transformer on it.
Picture 1.
The appearance of transformers TS-270, ST-270.
These transformers have several modifications, and all of them are interchangeable. These are TS-270-1 transformer types, TS-270-2, TSA-270-1, TSA-270-2, ST-270-1. Transformers Power TCA differ from TS transformers by the fact that their windings are made by aluminum wire. This was done to reduce the value of mass production of transformers.
The transformer circuit is shown in Figure 2, motch data and electrical characteristics of transformers, in Table 1.

* - Voltages are given for semi-windings (eg 5-15). Voltage of the entire winding 5-5 "equal to 5-15 + 15" -5 ".
There may be variants of TS-270 transformers, the windings of which 4-4 "and 9-9" are made separately.
- Winding 4-4 \u200b\u200b"(4-14 + 14" -4) corresponds to the data above.
- The winding 9-9 "(9-19 + 19" -9 ") contains only 6 (3 + 3) turns, respectively, the total nominal voltage of the entire winding is 2.2 volts.
A large problem is the absence of power transformers for amateur structures. Tanov, TN, TA and CCP on the market less, and the quality of them leaves much to be desired.
It should also be noted that the quality of the cores are - that more lottery! I came across the cores from TC180, characterized by the initial magnetic permeability of 5 (!!!) times.
More or less stable quality of OSM-0.4 cores, OSM-0.63, OSM-1.0, released to 82 years. Various TCs, TP, etc. you need to pre-simulate.
Siloviki at TSSH170.
The most common is iron TSSH170:
set of ears 30 * 60 mm, window 19 * 53 mm.
In the original, the primary has 2 turns on the volt, which gives the induction of 1.25 td, that for this iron, to put it mildly, is a bit too much.
Here are options for a good and very good security fork on this gland.
1. Bmax \u003d 0.8 T..
A) Permit - 675 turns with a wire with a PEV-1 with a diameter of 0.63 (0.67) mm, 9 layers of 75 turns in the layer. Active resistance Periods - 8.2 Ohm.
B) the screen of copper foil.
C) Secondary - 270 + 270 + 270 + 270 turns with a wire with a PEV-1 with a diameter of 0.51 (0.55) mm, 4 sections of 3 layers of 90 turns in the layer. The end of the first section connect with the beginning of the fourth, the end of the second with the beginning of the third. We obtain symmetric semi-windows with an active resistance of 12.3 +12,3 Ohm.
At the same time on the secondary, 175 + 175 volts. You can power the output cascades on the EC36-, 6C19P, 6C41S, 6C33S lamps.
Such a trance will be able to digest 140 W in the load, which is quite good.
2. Bmax \u003d 0.7 T..
For special gourmet
A) Permit - 780 turns with a wire PEV-1 with a diameter of 0.59 (0.64) mm, 10 layers of 78 turns.
Active impedance primary - 10.9 Ohm.
B) the screen of copper foil.
C) Security - the same as in the first example: 1080 turns with a wire of 0.51 (0.55) mm. Only in this case it will give 290 volts of the change, say, for a pair of 300V or 6P42С.
This trance is 120 W, too tolerant.
I note that for Andrei Nikitina and some other self-delicacles, I wind the influence transformers with an induction of 0.6 TL on this gland - almost extremely low BMAX value!
Siloviki on TC180-2, TC250-2m.
This iron is also very widespread.
Let's see what can be made on it.
PLR21 * 45 with a window 28 * 86 mm.
Gabritary winding - 11 * 80 mm.
Motat Calick for G72:
A) Permit - 1368 turns with a wire of PTTV-2 with a diameter of 0.63 (0.69) mm, 6 layers of 114 turns on each coil. Active primary resistance - 12.4 Ohm.
B) the screen of copper foil.
C) seconds - 3540 turns with a wire of PEV-1 with a diameter of 0.4 (0.45) mm, 10 layers of 177 turns on each coil. Active resistance 49 + 49 ohms. From the secondary, we remove 275 + 275 volts of the change. For G72, GMI11, GM5B and the lamps like them - the most!
Such a security film pulls 140 W, i.e. You can connect a pair of Gu72, with a total current of about 250 mA. And all this with BMAX \u003d 0.77 TL!
Silovik on TCA270.
This iron with a modest section of the PL25 * 45 has a giant window: 40 * 100 mm.
Those. You can wind more wire
To obtain an induction of 0.8 TLs, it is necessary to wind 1100 turns.
Mothe:
A) The primary - 1104 turns with a wire of PEV-2 with a diameter of 0.95 (1.03) mm, 6 layers of 92 turns on each coil. Active primary resistance - 4.8 Ohm.

C) seconds - 3120 turns with a wire PEV-2 with a diameter of 0.67 (0.73) mm, 12 layers of 130 turns in the layer. Active resistance - 18 + 18 ohms.
At the same time on the secondary, 306 + 306 volts.
The resulting trans will easily digest 310 W.
Silovik on TC270-1.
This trance is a bigger piece: pl25 * 50.
For the same BMAX, the turns must be smaller - 990.
A) the primary - 984 turns with a wire PEV-2 with a diameter of 1.08 (1.15) mm, on each coil of 6 layers of 82 turns. Active primary resistance - 3.5 Ohm.

This trance is energized and 400 W.
Silovik on OSM-0.4.
These security officials were originally calculated on ugly high induction - 1.5 T..
Hence all their shortcomings.
With normal induction - 0.8 TL - they are quite good.
A) Permit - 612 turns with a wire of Padevo 2 with a diameter of 0.9 (0.96) mm, 9 layers of 68 turns in the layer. Active primary resistance - 3.85 Ohm.
B) the screen of copper foil.
C) secondary - 276 + 276 + 276 + 276 turns with a wire PEV-2 with a diameter of 0.67 (0.725) mm.
In each section, three layers of 92 turns. The end of the first section is connected to the beginning of the fourth, the end of the second with the beginning of the third. We obtain two semi-windows with an active resistance of 8 + 8 ohms. AC voltage on the secondary - 195 + 195 volts.
Such a trans will pull 350 W (with a current density in the first 2.5 A / mm2, the power of all the transcenes described above is indicated at 2a / mm2).
Siloviki on TC70, TC80, TC90, TS100.
All these so different transformers are based on iron PM22 * 32 with a window 22 * \u200b\u200b60 mm. Gabritary winding 9 * 54 mm.
Iron them, fortunately, is very good and stable by parameters.
You can read them on Bmax \u003d 1 TL.

The power of such a trance is 90 W at 2,5 / mm2 in the primary.
Silovik on sh40 * 70 with a window 20 * 60 mm.
Gabritary winding 17 * 56 mm.
Somehow I came across a scale of these transformers with a very good gland (E3412, apparently).
The window is not enough, but something can be fit there:
A) Permit - 413 turns with a wire of PEV-1 with a diameter of 0.88 (0.94) mm, 7 layers of 59 turns in the layer. Active primary resistance - 3 Ohm.

Induction in the gland - 0.85 T.
Silovik on standard gland shn20 * 40 with a window 20 * 52 mm.
Gabritary winding - 17 * 47 mm.
These trances with transvitovsky gland also have suddenly and in large quantities. Iron - E330A - 0.35 (E3413A).
Therefore, I laid an induction of 1.1 T.
A) the primary - 1120 turns with a wire PEV-1 with a diameter of 0.5 (0.55) mm, 14 layers of 80 turns in the layer. Active primary resistance - 16 ohms.

Switching, as well as in previous cases: The end of the first section is connected to the beginning of the fourth, the end of the second with the beginning of the third. We get 185 + 185 volts with an active resistance of a half-winding of 40.6 + 40.6 ohms.
Power this transformer - 108 W at current density in the primary 2.5 A / mm2.
Silovik on the gland P15 * 32 with a window 26 * 82 mm.
This is a good 100-watt iron (E330A) was used in military instruments. Published very durable in appearance (but fragile in reality ) with black carbic coils. Warry winding 10.5 * 76 mm.
That's what you can get on it:

Silovik on the gland of the output from the "surf".
This is iron plm25 * 50 with a window 42 * 68 mm.
The case is aggravated by extremely stupid coils with a height of a brush of only 11 mm, although 18 mm can be made. Therefore, we make new frames with a dimming winding 18 * 64 mm.
A) Permit - 952 turns with a wire PEV-1 with a diameter of 0.88 (0.94) mm, on each coil 7 layers of 68 turns in the layer. Active primary resistance - 5.2 Ohm.

Just a pleasant trans
Finally, an option on good old E43-0.35 gland with a large window.
Sh32 * 43 with a window 28 * 60 mm. Gabritary winding - 25 * 56 mm.
To obtain an induction of 0.8 TLs, we need to wind 921 turns.
Let's see what happens:
