oil immersed transformer
Oil immersed transformers represent a crucial advancement in power distribution technology, serving as essential components in electrical systems worldwide. These transformers utilize insulating oil as both a cooling medium and dielectric material, ensuring efficient operation and enhanced safety. The transformer's core and windings are completely submerged in specially formulated mineral oil, which serves multiple critical functions. The oil efficiently dissipates heat generated during operation, prevents oxidation of internal components, and provides superior insulation properties. This design allows for optimal performance in high-voltage applications, ranging from 500 kV to 1200 kV. The transformer's robust construction includes radiators for heat dissipation, conservators for oil expansion, and sophisticated monitoring systems to maintain oil quality and temperature. These transformers are particularly valued in power generation stations, industrial facilities, and large-scale power distribution networks, where reliability and efficiency are paramount. Their design incorporates advanced features such as Buchholz relays for gas detection, temperature indicators, and oil level monitors, ensuring safe and continuous operation. The oil immersion technology also extends the transformer's operational lifespan by protecting critical components from environmental factors and electrical stress.
