全氢冷透平发电机

Turbine Generator With Hydrogen Cooling for Stator Winding and Rotor Winding

近年来,随着燃气-蒸汽联合循环的发展和燃气轮机单机容量的增大,全氢冷透平发电机再次引起人们的重视。回顾全氢冷发电机的发展历程,重点介绍西屋、GE、阿尔斯通和西门子公司的典型全氢冷透平发电机的冷却方式和结构特点。

In recent years,totally hydrogen cooled turbine generators(THCTG) have drawn attentions to us again,in company with improvements of CC generation technology and increasing unit capacity of gas turbine.This reviews the progress history of hydrogen cooled generator,and then put emphasis on introducing THCTG’s ventilation circuits and structure features of Westinghouse Co.,GE Co.,Alstom Co.and Siemens Co.
