Transformers TSSh-170 are designed for connection to an alternating current network with a voltage of 110, 127, 220 or 237 V with a frequency of 50 Hz. Permissible deviations in voltage and frequency of the power supply network do not exceed the values established by state standards and lie within ±5 and 0.1%, respectively.
The design of the transformer type TSSh-170 and manufacturing technology ensure reliable operation without breaks in the windings and other damage, as well as the appearance of corrosion on metal parts under repeated cyclic exposure to temperatures, high humidity and mechanical loads specified in the operating conditions of television receiver power transformers. Technological processes impregnation of transformer windings, their sealing and varnishing after installation increase the service life of both the transformers themselves and the reliability of the equipment as a whole.
Transformers type TSSh-170 are designed for installation on a metal chassis of a TV power supply with additional fastening with four screws.
The winding data of the windings and electrical parameters of transformers of the TSSh-170 type are given in Table. 1 and 2. The windings of transformers on armored magnetic cores are located on one coil.

Design, characteristics and disassembly of an AC transformer, using an example . Beginning radio amateurs are often interested in knowing how this or that device or unit works, as well as a radio component, even a simple one. Today I’ll tell you how the popular network one works. I decided to disassemble it because I no longer needed it - with such non-modern voltages, and I didn’t want to assemble a tube amplifier. The transformer had been lying in the closet for a long time, taking up quite a lot of space, and the weight was huge, but it was of little use.
So, the task of a transformer is to increase or decrease the voltage without changing the frequency. Structurally, this transformer has several diode bridges on the panel, a powerful quenching resistor, and a distribution and connection panel for connection.
Let's start disassembling - bend the plates and remove the clamp that compresses the plates of the magnetic circuit so that it does not rattle or hum during operation.
We knock out a couple of plates and pick them out with a screwdriver; the plates here are W-shaped with a separate closing plate.
After we have pulled out a couple of records, we tap the rest with a light hammer and disassemble them until there are no records left at all.
It turns out to be a rather large pile of iron, which will no longer be needed, but if you decide to assemble another transformer later, do not lose the plates.
Next comes the cardboard frame of the windings on which the coils themselves are wound, on top there is a low-voltage winding with the highest current, here these are 6-volt windings of incandescent lamps, then there are all the other windings with a lower current, and closest to the core is the primary winding which is connected to the 220 V network.
Each winding layer is insulated with paraffin and special paper. The winding wire is a copper single-core winding wire coated with varnish insulation. The coils here wound neatly coil to coil.
The transformer works like this: voltage is applied to the primary winding, which creates a magnetic field in the magnetic circuit, which is then induced in secondary windings. The voltage depends on the number of turns, and the maximum current usually depends on the thickness of the turns.
Here is information describing the TSSh-170 from the reference book: Single-phase low-voltage power transformers of the TSSh-170 type are used in power supply devices for black-and-white television receivers ULT-40, ULT-47-Sh and ULT-50-Sh.
