Strong Pollution Resistance of Oil-Immersed Transformers: Ensuring Stable Power Transmission

Oil-immersed transformers, as vital components in power systems, demonstrate excellent pollution resistance when faced with harsh environmental conditions and contaminants. They effectively withstand the influence of various pollutants, ensuring the normal operation and stable power transmission of transformers. This article explores the key features of oil-immersed transformers that contribute to their strong pollution resistance and their crucial role in ensuring the reliability of power systems.

 

  1. Protective Insulating Oil:

Oil-immersed transformers employ insulating oil as the insulation and cooling medium, which possesses outstanding pollution resistance properties. The insulating oil forms a uniform oil film, effectively isolating the transformer from external pollutants. Moreover, insulating oil exhibits high electrical insulation performance, effectively preventing breakdown and flashover caused by contaminants, ensuring the safe operation of the transformer.

 

  1. High Sealing Integrity:

Oil-immersed transformers are designed with a sealing structure that efficiently prevents the entry of external pollutants into the transformer's interior. The sealing structure includes the oil tank, oil seals, and insulation covers, which resist the intrusion of dust, moisture, salt spray, and other sources of pollution. This high sealing integrity not only protects the internal components of the transformer from contaminants but also contributes to extending its service life.

 

  1. Application of Corrosion-Resistant Materials:

The design and manufacturing of oil-immersed transformers incorporate corrosion-resistant materials, effectively resisting the corrosion and erosion caused by pollutants. For example, the use of corrosion-resistant coatings and materials to cover the external surfaces of the transformer prevents corrosion and damage to the metallic components caused by pollutants. This application of corrosion-resistant materials ensures the reliability and long-term stable operation of the transformer in harsh environmental conditions.

 

  1. Regular Maintenance and Cleaning:

Regular maintenance and cleaning are key to maintaining the pollution resistance performance of oil-immersed transformers. Regular inspections and cleaning of the external surfaces and cooling systems of the transformer help remove accumulated dust and dirt, preventing the accumulation and erosion of pollutants. Additionally, periodic replacement and monitoring of the insulation oil's condition ensure its cleanliness and optimal insulation performance.

 

Oil-immersed transformers possess strong pollution resistance, making them vital in ensuring reliable power transmission. The protective insulating oil, high sealing integrity, application of corrosion-resistant materials, and regular maintenance and cleaning collectively safeguard the transformer against the influence of pollutants. This robust pollution resistance enables oil-immersed transformers to operate stably in harsh environmental conditions, providing reliable electricity transmission and supply for power systems.
