Abstract

To meet the high reliability and efficient operation requirements of 220kV distribution equipment in electrolytic aluminum plants, this paper delves into the key issues related to design and reliability. It explores design optimization strategies from various perspectives, including electrical main wiring, equipment selection, and layout design. These strategies include using a double busbar connection to enhance power supply reliability and flexibility, and selecting equipment based on load characteristics and operating conditions. The reliability analysis considers the impact of factors such as short-circuit current, relay protection, and automation systems on the reliable operation of the distribution equipment, and proposes corresponding optimization measures. The research findings are valuable for improving the performance of 220kV distribution equipment in electrolytic aluminum plants and ensuring stable production operations, providing strong technical support for engineering design and operation maintenance.
