Oil immersed transformer main and auxiliary accessories

The main accessories of transformers include the following:
(1) Iron core: serves as a pathway for magnetic field lines and also serves as a support for the winding.
(2) Winding: As a path for current.
(3) Oil tank: As the outer shell of the transformer, the oil tank is filled with oil, playing a role in heat dissipation and insulation.
(4) Oil conservator: on the one hand, it can regulate transformer oil, ensure that the oil tank is full of transformer oil, and reduce the contact area between transformer oil and air, so as to slow down the deterioration rate of oil.
(5) Voltage regulation device: Change the tap of the coil, change the turn ratio of the high and low voltage coils, and adjust the voltage to stabilize it.
(6) Respirator: Equipped with an adsorbent to absorb moisture from the air.
(7) Explosion proof pipe: in case of internal fault of transformer, release the pressure to protect the transformer oil tank from damage.
(8) Thermometer: measures the upper oil temperature of a transformer.
(9) Bushing: It is not only the insulation between the lead and the ground (shell), but also plays a role in fixing the lead.
(10) Cooling device: dissipates the heat generated by the transformer during operation.
(11) Oil purifier: absorb the water, acid and oxide in the transformer oil circulating inside the transformer by means of silica gel, Activated alumina and other adsorbents filled inside, so that the oil can be purified and the service life of the oil can be extended. A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). The main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to their usage, they can be divided into: power transformers and special transformers (furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high-frequency transformers, impulse transformers, instrument transformers, electronic transformers, reactors, inductors, etc.). The circuit symbol commonly uses T as the beginning of the number, such as T01, T201, etc.
