Oil transformers type TME

Three-phase oil transformers to lower voltage type TME with capacity from 25 to 1000 kVA. The high voltage of transformers is 6 or10 kV and they are designed to be mounted on platforms for excavators and electric equipment.
Transformers TME are resistant to shocks and vibrations that occur when starting and stopping the rotary platform of excavators and inclination of 12 °. Transformers can be installed at a distance of 6 meters from the axis of rotation of the platform.
To increase the cooling surface of transformers TME from 25 up to 1000 kVA the radiators are mounted.
Transformers TME 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 or Dyn-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.
For mounting transformers TME on the platform, and also to drag them to the appropriate distances are provided corresponding skids.
Transformers TME 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
