In more detail

Transformer three - phase oil TMTO - 80 type

The transformer three - phase oil the TMTO - 80/0,38 - U1 type is intended for heat treatment of concrete and soil, power supply of the hand electric tool and temporary lighting.

Operating conditions

The transformer is intended for operation in areas with temperate climate, at:
not to explosive and chemically active environment.
installation height above sea level - no more than 1000 m.
The transformer is not calculated for work in conditions;
joltings, vibrations, blows in chemically active environment.
at frequent inclusions from power supply to 10 times a day.
Operating mode - long.
Ambient air temperature - 45C to + 40C.
Relative air humidity - no more than 80% at + 25C.

Structure of graphical symbol

TMTO - H/0,38 - U 1
T - the transformer three - phase.
M - cooling oil with natural air circulation and oils.
THAT is for heat treatment.
X - power rating, kVA
0,38 - rated tension of winding of VN, kV.
U1 - climatic modification and category of placement in accordance with GOST 15150

Technical characteristics

The TMTO - 80/0,38 - U1 transformer are issued with rated voltage of the primary winding (the highest tension) 380B inclusive and secondary winding (the lowest tension) - 42B, with step voltage regulation on winding of the highest tension or on winding of medium voltage. For this purpose transformers are equipped with tension switch which joins winding of medium voltage. Tension is regulated without excitation, at disconnected from transformer network from VN. Control bands are given in the table.
Scheme and group of the U/D/D/11 - 11 connection.
Power - 80 of kVA.
Hz frequency - 50.
Idling losses - 270 W.
Losses of short circuit - 2200 W.
Current of idling of - 2,3% .
The mass of oil is - 155 kg.
Total weight - 425 kg.

Design of transformers

Tanks of transformers welded, oval in the plan. Radiators are applied to increase in surface of cooling. Raising of the transformer is assembled carried out for the hooks located under upper frame of tank. Are below located stopper for oil descent, the crane (stopper) for oil filling, stopper for oil test capture, grounding bolt. On cover of tank there is inputs BH, HH, dilator, stopper for oil replenishment. The active part consists of the magnetic conductor made of cold - rolled electrotechnical steel, windings and the high - voltage switch. Windings of transformers from aluminum wires. Inputs of BH and HH of outside installation, removable, insulators checkpoints porcelain.

Assembly

Final assembly is carried out carefully and precisely according to Cd. Windings are established, and fasten on the corresponding rods of magnetic conductor then mounting of yoke, electrical connections and drying under vacuum is carried out. Before installation of active part in transformer tank, connection of windings, coefficient of transformation and angular error of shift of phase vectors is checked.

Final assembly

After careful drying and check of the moments of tightening of bolted connections the active part is established in transformer tank, the cover of the transformer fastens and it is filled with oil. At stage of final mounting, the transformer is completed with the ordered accessories.

Tests

All transformers are exposed standard and to acceptance tests according to GOST 11677 and normative documentation.
