Oil-Immersed Power Transformer

The 35kV Oil Immersed Transformer is a widely used electrical device, responsible for transforming the voltage of high voltage electrical grids to meet low voltage electrical demands. This article will explore the construction, operation, and application of the 35kV Oil Immersed Transformer. Construction The 35kV Oil Immersed Transformer is composed of two main components: the transformer body and the oil tank. The transformer body consists of a high-voltage coil, a low-voltage coil, an iron core, and insulation materials. The oil tank is responsible for storing the transformer oil, cooling the transformer, and maintaining electrical insulation. The oil tank is divided into two parts: an upper and lower part. The upper part contains auxiliary equipment such as a level gauge, oil temperature gauge, and gas relay. The lower part ensures that the transformer oil continually circulates, ensuring oil quality by reducing oxygen content, preventing pollution, and ensuring optimal performance. Operation The 35kV Oil Immersed Transformer operates based on Faraday's Law of Electromagnetic Induction. This law states that when a high voltage current passes through the high-voltage coil of the transformer, it generates an alternating magnetic flux, which induces an electromotive force in the low-voltage coil. The transformer core plays a critical role in facilitating the transformation of high voltage to low voltage. The oil in the transformer serves as a crucial element in maintaining the transformer's electrical insulation, absorbing and dissipating heat, and reducing the transformer's oxygen content to prevent insulation aging. Application The 35kV Oil Immersed Transformer is primarily applied in 220kV/110kV power substations in the power system. It transforms high voltage electrical energy into low voltage electrical energy, providing electricity to cities, industries, and rural areas. Additionally, transformers are used in other industries, including railways, aviation, mining, and military. Railway substations often have special requirements for transformers, including the need for high humidity, vibration resistance, and magnetic interference protection. In conclusion, the 35kV Oil Immersed Transformer plays a vital role in both residential and industrial settings and is critical in ensuring the efficient and smooth operation of the power system. Effective maintenance and management are necessary to ensure optimal performance and extend the transformers' lifespan. The 35kV Oil Immersed Transformer is a crucial component in power distribution systems worldwide, and its importance cannot be underestimated.
