TURBINE FOR TIDAL CURRENT POWER PLANT WITH A PRESSURE CONTROL DEVICE

摘要

PURPOSE: A tidal power turbine with a pressure controlling device is provided to protect a generator by releasing irregular pressure disturbance of seawater. CONSTITUTION: A tidal power turbine with a pressure controlling device comprises a casing(30), a generator(40), and a buffering unit. An inlet port(33) is formed on one side of the casing into which seawater flows. An outlet port(37) is formed on the other side of an outlet through which seawater flows out. The casing has an inflow chamber(35) of seawater. The generator comprises a rotor(43) which is rotated by the flow of the seawater. The buffering unit buffers the pressure gradient within the inflow chamber.
