| 摘 要： | 山东海阳及浙江三门核电1 250 MW机组离相封闭母线主回路的额定电流为36kA。 对其母线冷却采用强迫风冷、自然冷却2 种方式进行了技术和经济比较，证明了自冷式母线的设计、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，运行费用低。 因此，建议大电流封闭母线采用自然冷却方式。

| Abstract: | The rated current of enclosed bus-bar main circuit is 36 000 A for 1 250 MW units in Shandong Haiyang and Zhejang Sanmen Nuclear Power Stations.The self-cooling and forced-cooling options for bus-bar are analyzed through technical and economical comparisons,which has proved that the natural cooling bus-bar is of simple design,manufacture and installation without accessory for air cooling,high reliable operation,less maintenance and less operation cost.So the natural cooling mode is recommended for the large... |
