摘　　要：提出机组在基建、大小修期间检验发电机内冷却水系统通流情况的方法,利用发电机冷却水流量测量和热水流试验,检查发电机定子冷却水管道的通流情况,发现其分支管道的堵塞情况,防止机组在运行中发生发电机损坏事故。This article deals with the methods used to check the working conditions of the cooling water system of a turbogenerator in construction, during overhaul or in maintenance. By means of the flow measurement of generator cooling water and hot water flow tests, we can find the restricted or blocked branch piping so as to prevent the inservice generator from damage.

关 键 词：汽轮发电机 定子冷却水 流量测量
