二滩水电站550kV扩建工程GIS母线涡流损耗的论证与探讨

摘要

550kV ZF15-550 GIS is used at enlarging enginnering of ertan hydropower station. Taking 550 kV/4000 A busbars of aluminium, stainless steel and boiler steel as research subjects separately, the backset wastage is calculated and analyzed with finite element analysis method. Through comparing, the economic and practical project is obtained.%　　二滩水电站550 kV扩建工程采用ABB ZF15-550型GIS。分别以铝材、不锈钢、锅炉钢550 kV/4000 A母线为研究对象，采用有限元分析方法对涡流损耗进行了计算、分析，并通过比选，得出了经济、实用方案。
