Hydraulic circuit regulated by iron pipes with water take-off at the top of an existing dam, uses turbines at different heights on face of dam fed by pipes from the top of the dam, with valves allowing each turbine to be bypassed

摘要

The hydraulic circuit has three turbines (TA,TB,TC) at different heights, on the outside of the dam wall. The turbines are supplied through pipes. Water is taken off at the top of the dam, with the intake between 2 and 5 meters below the water surface. Water is carried down to the turbines, which are connected in series. Valves (3-8) that can divert (DA,DB,DC) flow past each turbine.
