浅析发电机运行中的漏氢

Essay on Hydrogen Leakage of Hydrogen Cooled Generator

漏氢是氢冷发电机运行中普遍存在的现象,漏氢量则是氢冷发电机安全运行的主要技术指标之一,漏氢的大、小标志着发电机冷却效果的好坏,显示了发电机运行的经济性、安全性。所以对运行中氢冷发电机漏氢(量)的控制就显得十分重要。发电机漏氢的因素很多,涉及到运行、检修等各个方面,本文以焦作电厂3号、4号氢内冷汽轮发电机为例,讨论其运行中漏氢的现象、原因与控制。

Leakage of hydrogen is a general phenomenon in the running of hydrogen cooled generator. The amount of leakage is one of the prime qualications of hydrogen cooled generator.The quantity of hydrogen leakage test the efficiency of generator cooling system and show the economy and safety capability of the generator.There are many factors that can cause hydrogen leaking, which involves the operation and overhauling quality of the generator and so on.Here taking #3 generator #4 enerator for example, we analyse the phenomenon cause and reducement of the hydrogen leakage.
