Ltd. (hereinafter referred to as quasi electric) 2 * 330MW units, is north from French ALSTOM technology and components from the North assembly water hydrogen cooled brushless excitation generator, the stator winding and rotor winding in cold water hydrogen inner cooling, iron core and other components of hydrogen cooling. The hydrogen is forced to cycle by a rotary fan mounted at both ends of the rotor and cooled by two sets of hydrogen coolers arranged at the top of the stator frame. The hydrogen system is composed of generator stator shell, end cover, hydrogen cooler, seal tile, sealing oil system and hydrogen pipeline. Type T255-460 rated power 388.2MVA, rated current is 9339A, the power factor is 0.85, Y connection, the excitation voltage is 542V, rated current is 2495A, the hydrogen pressure is 0.3MPa, cooling water flow rate is 475m3/h, the cooling water temperature is 33 DEG C. The structure is as follows: Inspection and control of concealed seal point and hydrogen line by 4.3.3 In the generator maintenance focus on easy to overlook some of the hidden seal disintegration is a dead, such as thermal sealing wire terminations, interturn short circuit detector terminal, generator installed at the bottom of the hole, the generator outgoing line casing flange and seal the hydrogen pipeline, dont neglect due to catch the progress of these points to the maintenance. Remember that any seals are aging,
