摘要
本文中作者对±1100kV直流输电(High Voltage Direct Current,HVDC)工程中的一台换流变压器初始设计方案的绕组温升进行了计算,发现了网侧绕组热点温升存在的问题,并通过试验验证了计算的准确性。
The temperature rise of the winding in initial design scheme for a converter transformer in the ±1100 kV direct current transmission project is calculated by the authors in this paper. The problems existing in the hot spot temperature rise of the winding on the grid side are found, and the accuracy of the calculation is verified by test.
