Transformers is one of the types of distribution transformers, in this type of transformer tank filled with oil. The special design of this type of transistor has made it used in many industries. The desire that this type of transformer has compared to other oil transformers is its tank design. Oil circulation makes the transformer cool. But if the oil is in contact with the air, it will be eroded. In fact, the oxygen in the air if combined with the oil, the sludge around the nucleus and coils, prevents the oil from circulating and the function of the oil. The device is impaired. Transformers are also divided into two types of hermetic transformers with gas cushion and hermethrough transformer without gas cushions.

Oil transformers are transformers that use oil to store transformer at healthy temperature levels. The reason for naming these transformers to the oil transformer is that they use a cooling or insulated liquid that is made of mineral oil. It has high resistance. So if it is exposed to high temperatures and chemicals, it is very durable. The transformer coils and magnetic circuits are immersed in the oil, causing the device to cool. As we have said, the oil transformer uses combustible liquids to cool. As a result, it is very suitable for outside places. Of course, this feature is also a disadvantage of this device.
Currently, given the advancement in oil transformer technology, it is possible to replace flammable oil with liquids that are more stable and less flammable, and the oil transformer can be used in places of environmental standards. They also have better cooling transits than other transmuts, as the fluid in this type of transistor creates better cooling conditions. The advantage of oil transformers is that units can withstand more pressure. Also repairing this type of transformer is low -cost compared to other transformers.

You may also have repeatedly asked what the difference between the hermestic and oil transformer, in the oil transformer, the oil plays a key role, such as cooling, insulating and absorbing air humidity. The coils are placed inside the oil tank. The oil used in this type of transformer is mineral, but it should be noted that ascorl should not be used because of its toxicity and damage to environmental conditions. But in hermitter transformers, the oil tank is not elastic, and in low powers, increased oil volume is compensated and in high powers the nitrogen bag is used to absorb moisture. Protecting and preventing damage to transfers is used, because if the oil becomes too hot, the transformer may explode. The most important difference between hermitted and oil transformers is that the hermetic transformers do not need maintenance and for use in external places such as Wet or dusty environments are very suitable. These transists are used in chemical plants, oil and gas terminals. In fact, places where access to regular maintenance is difficult to choose this transformer is very suitable.
Transformer is a device that helps power from one circuit to another without frequency change and is used to supply electrical energy. Transformers have different types and people choose the device based on the need, application and environmental conditions.

Special design that has a trans -hectic has made it used in a wide range of sectors. The most important advantage of these transformers over other types of oil transformers is its tank design. Oil is considered as one of the most important parts in the hermitter transformer (which cools the transformer by its circulation), which is eroded if exposed to open air, that is, oxygen in the air if combined with The oil elements cover the sludge around the nucleus and the coils and prevent the oil from circulating. As a result, the heat of the nucleus and coil rises and the function of the device is impaired. These transists can be used due to the lack of oil erosion and the need to replace the oil in areas where the transcription is not possible due to the installation conditions as well as the humid areas. Transformers are converted into two categories of hermitic transformer with gas cushions and hermeter transformer without gas cushions.

This type of transistor, also known as trans -hermethmic tank, has an empty space, above the oil surface filled with neutral nitrogen gas. In this type of transmitic transmitter, a specific level for oil is defined. The reason for using nitrogen gas, as mentioned, is neutral that it does not react with the oil and does not erode the oil. In addition, there is no other misconduct on the interior parts. When expanding the oil, the atoms of the gas are compressed, thereby providing the space for oil expansion, and by the oil contraction, the atoms return to their original state. One of the problems of the hermestic transformer is that any abnormal conditions such as sudden flow increases, lightning causes some gas to dissolve in the oil and cause bubbles in the oil that will disrupt the cooling function of the oil.

In hermitter -free, gas -free transformers are actually transformer that prevents direct air and oil contact with their completely closed tank, thereby avoiding air and oil contact. This transformer has reservoirs whose walls are elastic designed to expand with oil expansion of tank walls, thereby providing the space for increased volume of oil, and when the oil contracts the walls to the walls. The first state returns. The active part of the transmitic transmitter without a gas cushion that includes coils and cores is completely in the oil.
