  Ұлғайтқыш - трансформатор багындағы майдың температура салдарынан өзгеруін реттеп отырады.
  The extender is the regulation of the oil due to temperature in transformer bug
  Расширитель – это регулирование масла за счет температуры в трансформаторном баге

  Трансформатор багы – трансформатордың активті бөлігі орналасатын ыдыс
  Transformer bug is a reservoir in which is located the active part of the transformer
  Трансформаторный бак – это резервуар, в котором расположена активная часть трансформатора

  Газды реле бакта бұзылған орындар,майдың ыдырауынан газ бөлінуінен сақтап, сигнал береді.
  Gas relay, destroyed places in the tank, provide alarm, preventing the release of gas due to the decomposition of oil.
  Газовое реле –предотвращает и дает сигнал при нарушении в баге и выделение газа при разложении масла

  Laminated and well insulated iron cores are used for the completion of the magnetic circuit and to reduce iron and eddy current losses. Laminated sheets are assembled in a series manner and to form the laminated core. The thickness of a core is kept 0.5 mm. The windings are wounded in the limb. Insulations are used between the high voltage and low voltage windings to prevent the short circuit. The primary and secondary winding are placed for the transformation of power. These may be wound in cylindrical or sandwich types. The tank or box protects all the windings and cores from the atmospheric effect . The three phase winding is inserted info the tank. The conservator is the drum, which is used as oil storage tank and it is mounted on the top of the transformer. The oll level indicator is used to indicate the oll level in the conservator. A breather is used to prevent the transformer oll from the atmospheric pressure. Buchholz relay is installed between the transformer tank and conservator. Buchholz relay is a qas actuated relay installed in oil immersed transformers for protection against all kinds of faults. Buchholz relay detects the incipient faults at a stage much earlier than is possible with other forms of protection. The bushings provide proper insulation between live conductor and earthed tank. Explosion vent provides an exit path to the qases produced in the transformer due to all kinds of faults. Diaphragm is used to discharge excess pressure in the atmosphere when excess pressure is developed inside the transformer during loading. These are used for transformer cooling purpose. Temperature qauqe is a thermometer which is mounted on the transformer to measure its temperature. Drain vaive is used to drain oil from the transformer . Oil is used for cooling purpose. The oil used should not have a flash point less than 1600 C. The freezing point should not be higher than 150C and ite viscosity should be 300C and 150C.
