L'usine Hydro-électrique de Blondel.
The Blondel Hydro-Electric Plant
L'usine André Blondel est aujourd'hui toujours la centrale hydro-électrique la plus productive de France. L'exploitation de l'usine est assurée par E.D.F.
The André Blondel Power
Plant is today the hydro-electric power station
most productive of France.
The exploitation of the factory is ensured by
E.D.F.
La production annuelle est en moyenne supérieure à 2 milliards de kwh. Il faudrait brûler 369 000 tonnes de fuel pour obtenir la même quantité d'électricité.
L'usine-écluse de Blondel permet un trafic fluvial très intense: environ 5700 bateaux, de commerce ou de plaisance qui empruntent chaque année la voie navigable à grand gabarit qu'est le canal de dérivation.
The annual production is on
average higher than 2 billion kWh. It would be
necessary to burn 369 000
tons of fuel to obtain the same quantity of
electricity.
The factory-lock of Blondel
allows a very intense river traffic:
approximately 5700 boats,
of trade or pleasure which borrow each year the
inland waterway from large
gauge which is the diversion canal.
A l' intérieur de l'usine, on trouve la salle des machines de dimensions impressionnantes comportant 6 groupes de type kaplan :
At the interior of the factory,
one finds the engine room of impressive size
comprising 6 groups of the
Kaplan type:
Chacune de ces turbines , équipée d'une roue-hélice à pales mobiles entraîne à la vitesse de 58000 K.V.A.qui produit du courant d'une tension de 10500 volts. Près de l'usine, le poste de transformation d' E.D.F. élève cette tension à 220 000 volts pour l'alimentation du réseau français de transport d'énergie électrique.
Each one of these turbines,
equipped with a mobile blade wheel-propeller
involves at the speed of
58000 produced K.V.A.qui of the current of a tension of 10500 volts. Close
to the factory, the switchyard of E.D.F. raise this tension with 220 000
volts for the French electricity grid.

Andre Blondel's Biography: Andre Blondel Another Biography
blondel
from the "Journal of the Optical Society of America"
(as a scientific unit of measurement)
A unit of luminance suggested in 1942, and named
for the French physicist A. E. Blondel
(1863-1938). One blondel is pi lumens per square meter per steradian;
it is equivalent to the
apostilb.
Parry Moon.
A system of photometric concepts.
Journal of the Optical Society of America, volume 32, pages 348-362
(June 1942).
The unit is pi times the lumens per square meter
per steradian. Such a name is
impossibly cumbersome, so a new name is proposed, the blondel, after
André Blondel who did
pioneer work in photometric nomenclature.
