The introduction of tubular type hydro turbine

 

The space between the poles of the bulb turbine rotor excitation winding is small, and the number of excitation ampere turns is limited, so a higher power factor is selected. The moment of inertia and inertia time constant of the hydro-generator of the bulb-type unit are small, so the speed rise rate β value of the unit during load rejection is larger, generally greater than 45%, and the runaway speed can reach 2.5 to 3.5 times the rated speed. Compared with the vertical turbine generator of the same capacity, the rated speed of the bulb unit can be increased by more than 10%, the inner diameter of the generator can be reduced by more than 25%, and the weight of the entire unit (including the turbine) can be reduced by 25%, which is more economical A reasonable model, mostly used for low-head hydropower stations with a working head range of 3~25m.
