Oil transformers type TMF

Three-phase oil transformers to lower voltage type TMF with capacity from 25 to 1000 kVA. The high voltage of transformers is 6 or10 kV and they are designed to be mounted on the outside and inside buildings.
Transformers TMF can work alone or in transformer substations.
To increase the cooling surface of transformers TMF from 100 up to 1000 kVA the radiators are mounted.
Transformers TMF are manufactured at the rated voltage of the primary winding 6 or 10 kV. Rated voltage secondary winding is 0.4 kV.
Scheme and connection group of windings Yyn-0, Dyn-11, Yzn-11.

Design features

Transformer tanks are rectangular. On the opposite narrow walls of the tank are provided fixing holes in which the screws are tightened.
Transformers TMF are equipped with conservator, which provides the right amount of oil under all operating conditions of the transformer and fluctuations of ambient temperature.
In order to protect the oil from external weather conditions on conservator is mounted silicone dehumidifiers.
The dryer is filled with a sorbent which absorbs moisture before the entry air from outside inside the transformer.
To check the oil level on the side of the conservator is mounted floating magnetic oil level indicator.
To check the temperature in the upper layer of oil in the transformer tank is mounted thermometer.
Oil transformers with capacity ratings above 1000 kVA are provided with a Bochholz relay
