摘要

This comprehensive bibliometric analysis of superconducting transformer research from 1993 to 2023 reveals significant growth driven mainly by China, the USA, and Germany, with nearly 25% of publications involving international collaboration. The study highlights key research themes such as AC loss reduction, high-temperature superconductors, and fault current limiters, which are critical for enhancing energy efficiency, grid reliability, and ecological sustainability. Superconducting transformers, leveraging materials with near-zero electrical resistance at cryogenic temperatures, promise substantial societal benefits including improved grid stability and reduced greenhouse gas emissions. However, widespread adoption faces challenges like high initial costs, technical integration difficulties, and a pressing need for effective policy frameworks. The analysis underscores that successful implementation depends on coordinated efforts among researchers, policymakers, and industry leaders, emphasizing targeted policy interventions such as strategic investments, supportive regulations, and fostering international research consortia. Furthermore, it advocates for developing technical guidelines and infrastructure compatibility standards to facilitate seamless integration into existing energy systems, aligning with broader energy transition and climate objectives. The findings call for enhanced governmental and industrial commitment to innovation, highlighting the transformative potential of superconducting transformers not only to modernize energy infrastructures but also to drive economic transformation globally through sustainable and cooperative international efforts.
