Core Viewpoint - The introduction of the first high-altitude environmentally friendly transformer using soybean oil in Maduo County, Qinghai Province, marks a significant advancement in sustainable energy technology in ecologically sensitive areas [1][12]. Group 1: Technology and Innovation - The 10 kV transformer operates using modified soybean oil instead of traditional mineral oil, which is difficult to decompose and poses environmental risks [3][4]. - Soybean oil has a nearly 100% biodegradation rate, significantly reducing pollution risks in case of leaks, and has a higher ignition point, enhancing operational safety [3][4]. - The development involved extensive research to improve the oil's resistance to aging and low temperatures, crucial for high-altitude environments [4][6]. Group 2: Environmental Impact - The transformer has a capacity of 400 kVA and uses approximately 275 kg of oil, expected to reduce carbon emissions by 660 kg per unit over its lifecycle, equivalent to the annual carbon reduction of planting 70 trees [6]. - The environmentally friendly oil is less harmful to the internal insulation materials of the transformer, potentially extending its service life by over 30% and reducing maintenance costs [6]. Group 3: Implementation and Future Prospects - The first pilot transformer was successfully tested in Xining four months prior, demonstrating reliable performance and paving the way for broader application in challenging environments [7][11]. - The successful deployment in Maduo County, at an altitude of 4,300 meters, showcases the technology's adaptability and reliability under extreme conditions [11]. - The initiative represents a replicable model for eco-friendly power grid construction, allowing for infrastructure development without compromising environmental integrity [11].
青海全面推广高海拔环保型配电变压器
10千伏植物油配电变压器是指在配网变压器中使用植物油作为绝缘物质,因植物绝缘油 提取自天然植物,具备良好的生物降解性,降解率近100%,发生泄漏时可迅速在自然环境 中分解,大幅降低变压器漏油对土壤和水源的污染风险。同时,植物绝缘油燃点更高,不易 燃烧,使设备运行更加安全可靠。相比之下,传统变压器普遍采用矿物绝缘油,这类油品多 源自石油提炼,在自然环境中极难分解,一旦发生渗漏,将对周边土壤和水源造成持久性污 染。 与普通食用植物油不同的是,植物绝缘油需要解决抗氧化稳定性不足和低温流动性受限 两大难题。国网青海省电力公司积极探索"大豆油基+复合添加剂"技术方法,选用大豆油为 基础油,融入添加环保型抗氧化剂和高效降凝剂,如同为变压器注入了"抗衰老屏障"与"低 11月5日,从国网青海省电力公司获悉,继西宁地区首次试点运行后,10千伏植物油配 电变压器在青海省果洛藏族自治州玛多县挂网运行,标志着高海拔环保型变压器在青海进入 全面推广阶段。这是我国首次研发和推广应用高海拔环保型变压器,为三江源地区生态保护 与电网建设协调发展树立了新的典范。 此次在玛多县挂网运行的10千伏植物油配电变压器容量为400千伏安,变压器整体用油 ...
