Description

Transformers TMF power oil series

- three-phase dvukhobmotochny lowering with flange conclusions. With power from 250 to 1000 kVA are issued and are intended for internal and external installation. Can work as independent products, and as a part of KTP.
Radiators are applied to increase in a surface of cooling in transformers.

TMF 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.

Tanks of transformers - rectangular. On narrow opposite walls of a tank inputs which are closed by boxes with consolidations are located.
Maslorasshiritel provides 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. The 1000 kVA transformers are supplied with the gas relay.
