Description
Transformers three-phase oil the TMG type with gofrobaky natural oil cooling, with the switch without excitement, included in the alternating current main with a frequency of 50 Hz, are intended for transfer and distribution of the electric power in the conditions of a temperate and frigid climate. Transformers are not intended for work in the conditions of jolting, vibration, blows, to explosive and chemically active environment. In production of TMG transformers it is applied the technical solutions increasing their reliability and reducing operational expenses.

Transformers are executed in tight execution with full filling with oil. There is no dilator and a gas pillow. Temperature changes of volume of oil are compensated by change of volume of corrugations of a tank due to their plastic deformation.

The message of oil with environment is not present that excludes moistening, oxidation and shlamoobrozovany oils. Before filling oil is decontaminated, filling is made in a special vakuumzalivochny chamber at deep vacuum that provides removal oil oxidation is excluded from the oil dissolved in it air, removal from isolation of air inclusions, the high electric durability of isolation of the transformer is provided. Oil does not change the properties during all service life of the transformer.

Excessive pressure in tanks at operation of transformers does not exceed 0,2-0,25 kgfs/cm2. For restriction of pressure in tanks at overloads with power from 25 to 250 kVA safety valves are installed, and are installed in the 1000 kVA transformers above, the gas relay, thermosignalling device TKP-160sr. For control of level of oil transformers of all capacities are supplied with an oil indicator of float-operated type.
