In the context of the global acceleration of the transition to clean energy, wind power as an important form of renewable energy utilization, is booming. And behind the stable operation of wind farms, oil-immersed transformers play an extremely critical role, providing a solid guarantee for the efficient development of the wind power industry.
Oil-immersed transformers play an irreplaceable role in power transmission. With the continuous growth of power demand, power plants are often far away from the concentration of electricity cities and industrial areas. In the long-distance power transmission process, in order to reduce line losses, the voltage needs to be greatly increased. Oil-immersed transformers, with their excellent performance, can efficiently realize the voltage transformation. The step-up transformer converts the low voltage output from the power plant to a high voltage, allowing the power to be transmitted over long distances with low losses on the transmission lines. For example, in cross-regional ultra-high-voltage transmission networks, many large oil-immersed step-up transformers boost power from power plants to the million-volt level, ensuring that power can be stably delivered across hundreds or even thousands of kilometers to areas where electricity is needed.
Oil-immersed transformers are also indispensable in the field of power distribution. Once the high-voltage power has been delivered to the substations near cities and factories, it is once again reduced to a level suitable for the user by means of an oil-immersed transformer. Whether it is a distribution transformer that provides 220 volts of electricity to millions of households, or a special transformer that meets the 380-volt requirements of industrial production, oil-immersed transformers are able to accurately regulate the voltage to ensure the normal operation of all types of electrical equipment and industrial machinery.
In response to the complex power environment and special scenarios, the importance of oil-immersed transformers is more and more prominent. In some extreme weather areas, such as high temperature, high humidity or strong wind and rain environment, oil-immersed transformer because of its use of oil as insulation and cooling medium, with good heat dissipation performance and stable insulation characteristics, can continue to operate stably. In industrial production, especially for power stability requirements of the electronics, chemical and other industries, oil-immersed transformers reliable power supply to ensure the continuous operation of the production line, to avoid voltage fluctuations or power outages caused by huge economic losses.
In addition, oil-immersed transformers in wind farms to ensure the stability of the power output is also a great success. Wind power generation by the natural wind power influence, the output power fluctuation. Oil-immersed transformer can be unstable power buffer and regulation, through its own electromagnetic characteristics, the voltage and current optimization, reduce the wind changes caused by voltage fluctuations and current shock, so that the output of power is more stable, in line with the grid access standards. This feature is crucial for maintaining the stability of the power grid, avoiding the impact on the power grid caused by the unstable power output of wind farms and ensuring the reliable operation of the entire power system.
It can be said that the oil-immersed transformer as the core equipment in the power system, from the source transmission of electricity to the terminal distribution, throughout the entire power supply chain. It is not only the key to ensure stable and efficient transmission and distribution of electricity, but also an important cornerstone to support the economic development of modern society and people's good life. With the continuous development of power technology, oil-immersed transformers are also continuing to innovate and upgrade, the future will continue to play a more important role in the power system for the prosperity and progress of society.
