110千伏超一级能效变压器在三明尤溪投运

Core Viewpoint - The successful commissioning of the 110 kV ultra-high efficiency transformer at the Shentai Substation in Sanming marks a significant advancement in energy-saving technology within China's power sector, contributing to the country's green and intelligent grid development [1][3][5]. Group 1: Project Overview - The project is a national key energy-saving transformation initiative, developed collaboratively by State Grid Fujian Electric Power Research Institute and China Electric Power Research Institute, with on-site installation and debugging managed by State Grid Sanming Power Supply Company [3][4]. - The transformer utilizes a 0.20 mm ultra-thin oriented silicon steel, which is significantly thinner than the traditional 0.23 mm silicon steel, leading to reduced energy consumption and improved power transmission efficiency [3][4]. Group 2: Environmental Impact - The new transformer is projected to save approximately 5.5 million kWh of electricity over its 30-year lifespan, equivalent to the annual electricity consumption of 5,000 households, while also reducing coal consumption by 1,600 tons and cutting CO2 emissions by 4,400 tons, comparable to planting 240,000 trees [4]. - The reduction in grid losses will help stabilize power supply costs, providing tangible "green dividends" [4]. Group 3: Implementation and Collaboration - The project involved extensive collaboration during the design phase, ensuring that material specifications and performance requirements were aligned with local operational conditions [4]. - State Grid Sanming Power Supply Company maintained strict oversight throughout the installation and debugging processes, ensuring quality control and adherence to project specifications [4][5]. Group 4: Strategic Importance - This initiative represents a practical step towards building an environmentally friendly power grid and contributes to the establishment of a new energy system in China, serving as a replicable model for nationwide green and low-carbon transformation efforts [5].
