Abstract

Ce dispositif pour assurer le refroidissement des équipements électromécaniques d’une centrale hydroélectrique, comprend au moins une canalisation d’accès ou conduite forcée (2) de l’eau, au niveau de la ou des turbines (3) actionnant un alternateur ou générateur (4) en vue de la production d’électricité, ce dispositif comprenant un circuit fermé au sein duquel circule un fluide caloporteur et notamment de l’eau, sous l’action d’une pompe, acheminant ledit fluide caloporteur ou l’eau au niveau d’un ou de plusieurs échangeurs individuels associés auxdits équipements électromécaniques, ledit fluide caloporteur ou l’eau étant refroidi au contact d’une source froide (1). Le refroidissement du fluide caloporteur ou de l’eau circulant dans le circuit de refroidissement par la source froide est réalisé au moyen d’un échangeur principal, constitué par la ou les grilles de filtration (8) positionnée(s) en amont de la (des) canalisations d’accès (2) de l’eau au niveau de la ou des turbines (3), ladite (lesdites) grilles étant constituée(s) de tubes (10, 11, 12) au sein desquels circule le fluide caloporteur ou l’eau et de barreaux (13) solidarisant partie desdits tubes entre eux. Figure pour l’abrégé : Fig 1This device for cooling the electromechanical equipment of a hydroelectric power station comprises at least one access pipe or penstock (2) for water, at the level of the turbine (s) (3) actuating an alternator or generator ( 4) for the production of electricity, this device comprising a closed circuit within which circulates a heat transfer fluid and in particular water, under the action of a pump, conveying said heat transfer fluid or water at the level one or more individual exchangers associated with said electromechanical equipment, said heat transfer fluid or water being cooled in contact with a cold source (1). The cooling of the heat transfer fluid or of the water circulating in the cooling circuit by the cold source is carried out by means of a main exchanger, consisting of the filtration grid (s) (8) positioned upstream of the ( of) water access pipes (2) at the level of the turbine (s) (3), said grid (s) consisting of tubes (10, 11, 12) within which the coolant circulates or the water and bars (13) joining part of said tubes together.
