Introduction of Bulb Hydro Turbine Generator
Bulb-type hydro-generator refers to a hydro-generator in which the generator and bearings are arranged in a sealed shell shaped like a light bulb. The bulb-type water turbine generator is connected to the water turbine with a straight shaft and arranged in the flow channel. It is characterized by a compact and complex structure, and has special requirements such as moisture-proof and leak-proof. Since the bulb-type hydro-generator is installed in the underwater flow channel, the winding is prone to damp when it is stopped, so its rated voltage is lower than that of the general hydro-generator. The space between the poles of the rotor excitation winding is relatively small, and the number of excitation ampere turns is limited, so a higher power factor is selected.
