"作为特高压设备中的'高精尖'产品，高端换流变压器是特高压直流输电工程的'核心心脏'，在电力跨区 域传输中承担着交直流转换'枢纽'和电压与功率'调节器'的作用。"特变电工相关负责人介绍，在"宁电 入湘"工程的受端衡阳换流站，高端换流变负责将高压直流电逆变为交流电，匹配衡阳本地电网电压等 级，实现与用户端的无缝衔接，承担着绿电转化的核心使命。 据介绍，±800千伏高端换流变压器，每台高达14.8米(约四五层楼)，重达570吨，长26.5米，宽8.4米，拥 有完全自主知识产权。这14台"巨无霸"，像威风凛凛的将军，保证了电力源源不断地供给湖南。 业内人士指出，"宁电入湘"工程全线竣工后，不仅将满足湖南用电需求、优化能源结构，更推动宁夏清 洁能源大规模外送，实现跨区域能源优化配置。 人民网北京8月20日电 (记者夏晓伦)8月20日，我国首条"沙戈荒"风电光伏大基地外送特高压通道 ——"宁电入湘"工程实现整体竣工，正式具备800万千瓦满负荷送电能力。该工程构建起新能源供给消 纳体系样板，每年可向湖南输送超360亿千瓦时清洁电力。 据了解，"宁电入湘"工程始于宁夏回族自治区中卫市中宁换流站，一路途经甘肃、陕西、重庆、湖 ...

Core Viewpoint - The completion of the "Ning Electric into Hunan" project marks a significant milestone in China's renewable energy infrastructure, enabling the transmission of over 36 billion kilowatt-hours of clean electricity annually to Hunan province [1][2]. Group 1: Project Overview - The "Ning Electric into Hunan" project is China's first "Shagohuang" wind and solar power base external high-voltage transmission channel, with a total investment of 28.1 billion yuan [1]. - The project spans 1,616 kilometers, starting from the Zhongning converter station in Ningxia and passing through Gansu, Shaanxi, Chongqing, and Hubei before reaching Hengyang in Hunan [1]. - The project is designed to have a full-load transmission capacity of 8 million kilowatts [1]. Group 2: Technological Innovations - The company has implemented digital quality management throughout the entire process of high-end converter transformer production, achieving a 100% qualification rate for batch production [2]. - The company has developed or optimized various products tailored to the project's specific geographical and climatic conditions, including steel-core aluminum stranded wire and epoxy resin-impregnated paper capacitive DC bushings [2]. Group 3: Economic and Social Impact - The project not only meets its economic and social objectives but also enhances the capabilities of the team involved, leading to technological advancements and the development of new products [2]. - The successful execution of such large-scale power engineering projects serves as a reference for the high-quality development of the power equipment industry in China [2].
