摘要
邹县发电厂1000MW超超临界机组封闭母线主回路的额定电流为26500A。其冷却方式采用强迫风冷还是自然冷却?通过技术和经济比较,证明自冷式母线的设计、制造及安装相对简单,又无风冷方式的附属设备,运行可靠性较高,维护工作量少。因此,建议该工程封闭母线采用自然冷却方式。
The rated current of enclosed bus-bar main circuit is 26 500 A for 1000 MW extra supercritical units in Zouxian Power Plant. The option for its cooling is forced air cooling or natural cooling. Through the technical and economical comparison it has proved that the self-cooling bus-bar is of simple design, manufacture and installation without accessory for air cooling, high reliable operation and less maintenance. So the natural cooling mode for the enclosed bus-bar is recommended for the project.
