The Factors Affecting Analysis Of Generator Hydrogen Humidity And Dehumidification Research

Currently most of the internal generator power plants using hydrogen to cool the stator core and the rotor,However,due to the normal operation o,a small amount of hydrogen mixed with the inevitable water vapor generated within the generator.It may cause condensation,This insulation and safe operation of generators pose a major threat,It is necessary to remove hydrogen contained water and hydrogen gas to maintain a low dew point.Hydrogen generator system from steam generator seal oil in the water,the generator seal oil in the water from lubricating oil,lubricating oil in the water from the turbine shaft seal system.Seal gap too large,the turbine shaft seal steam system leaks,steam leaks through the adjacent bearing block oil turbine,oil return suction system and then into the main fuel tank,causing excessive water content of lubricating oil.So if you want to reduce the dew point generator hydrogen system must begin from the viewpoint of reducing the turbine shaft sealing gap,After water vapor into the turbine lubricating oil,lubricating oil filter system can remove part of the water,the water enters the generator seal oil system can also be removed by vacuum tank and vacuum pump.But after intercepting layers still a small amount of water vapor into hydrogen generator system,then only remove the water through the generator hydrogen drier,it can maintains a dew point in the hydrogen system within the required range.By analyzing the hydrogen generator system and process water vapor source,the source and analyze all aspects of the middle,using different ways to remove moisture.So that generators can be more safe and stable operation,and create more economic value for the state and society.
