A dry type transformer is a type of transformer that uses air in an insulating material for insulation. Compared with traditional oil-immersed transformers, dry type transformers have better environmental adaptability and fire resistance, so they are widely used in some special environments.
In high temperature environments, the performance of dry type transformers can generally be maintained better. First of all, the dry type transformer has no liquid insulating agent, so it will not cause the gasification or degradation of the insulating oil due to high temperature, thus improving the safety and reliability of the system. In addition, the insulating materials used in dry type transformers generally have high temperature resistance and can maintain good insulation performance in high temperature environments.
In addition, dry type transformers can better dissipate heat due to the absence of oil. In a high temperature environment, the transformer will be subjected to a greater heat load. And the heat of the dry type transformer will rapidly be distributed through the radiator and natural convection to ensure that the transformer works within the normal temperature range. Therefore, dry type transformers are not easy to overheat in high temperature environments and can maintain good performance.
In addition, dry type transformers also have some other advantages, for example, no maintenance can eliminate trouble that oil-immersed transformers need regularly change the insulation oil; Good corrosion resistance makes dry type transformers work in harsh environment for a long time; No noise, no pollution, etc. These advantages make the performance of dry type transformer in high temperature environment better guaranteed.
However, it should be noted that in extreme high temperature environments, the working parameters of the transformer may need to be adjusted or some additional measures taken to ensure its normal operation. In addition, for some special application scenarios, such as high temperature, high humidity, explosive and other environments such as mines and chemical plants, it may be necessary to use more special dry type transformer design and materials to meet specific requirements.
Performance optimization strategy in high temperature environment
Improve ventilation
In high temperature environment, the ventilation condition of dry type transformer is very important to its heat dissipation performance. Therefore, the ventilation design of the transformer should be optimized to ensure smooth air flow. At the same time, regularly clean the ventilation duct to prevent dust from affecting the heat dissipation effect.
Enhanced insulation measure
In high temperature environment, the insulation performance of dry type transformer may be affected to some extent. Therefore, insulation measures should be strengthened, and higher performance insulation materials and more reasonable insulation structures should be used to improve the insulation performance and high temperature resistance of the transformer.
Optimized load distribution
Reasonable adjustment of transformer load distribution to avoid overload operation. By optimizing the load distribution, the operating temperature of the transformer can be reduced and its service life can be extended.
Strengthen maintenance
Perform regular maintenance on the dry type transformer, including cleaning the heat sink, checking the insulation status, and replacing the aging parts. These measures ensure that the transformer maintains stable performance in high temperature environments.
