  • Generator seal assembly
    Patent number: 11378188
    Abstract: A generator seal assembly for preventing leakage of coolant in a generator is presented. The seal assembly includes a coolant side seal ring having a plurality of coolant side seal ring segments. The coolant side seal ring segment includes a seal fluid channel and radial holes circumferentially distributed along the seal fluid channel from leading edge to trailing edge through which seal fluid enters the seal fluid channel. Additional radial holes are circumferentially distributed along the seal fluid channel in a region near leading edge. Additional seal fluid enters the seal fluid channel in the region near leading edge through the additional radial holes such that pressure of seal fluid in the region is increased higher than pressure of the coolant to prevent leakage of the coolant in the region near leading edge due to ration of generator shaft.
