Transformers power oil

Transformers power oil - three-phase dvukhobmotochny lowering common industrial application. With power from 25 to 1600 kVA are issued and are intended for internal and external installation.
Radiators or corrugated walls are applied to increase in a surface of cooling in transformers.

TM transformers are issued on the rated voltage of primary winding of 6 or 10 kV. Rated voltage of a secondary winding of 0,4 or 0,23 kV. Scheme and group of connection of windings U/Un-0, D/Un-11 or U/Zn-11.

Transformers are supplied maslorasshiritepy, providing availability of oil at all operating modes of the transformer and fluctuations of ambient temperature.
For protection of oil against influence of the external atmosphere the transformer is supplied with an airdehumidifier. The airdehumidifier is filled with a sorbent which absorbs moisture from the air coming to the transformer.
For control of level of oil on the transformer the float-operated oil indicator which fastens at an end face of a maslorasshiritel is established.
For measurement of temperature of the top butter layers in a tank the transformer is supplied with the arrow thermometer. Transformers with power from 1000 kVA are supplied with the gas relay.
