Title (EN) ELECTRIC SCREEN DEVICE
(FR) ECRAN ELECTRIQUE
Abstract: front page image
(EN)In an electric screen device (2) which is constituted of a pair of electrode members (12 and 12) opposedly positioned on both sides of a water inlet channel (1) and a DC pulse impressing device (13) for impressing a DC pulse across the members (12 and 12) and checks the entrance of a living thing into the channel (1), the product of the peak value of the electric field created between the members (12 and 12) and the body length of the living thing to be checked is more than 0.1 V, the impressing time of the DC pulse falls within a range from (2) msec to 200 msec, and the duty factor of the DC pulse is less than 0.5.
(FR)L'invention concerne un écran électrique (2) comprenant une paire d'électrodes (12 et 12) disposées de manière opposée de part et d'autre d'une conduite d'arrivée d'eau (1) et un dispositif (13) servant à appliquer une impulsion de courant continu à travers les éléments (12 et 12) et vérifiant l'entrée d'un corps vivant dans la conduite (1). Le produit de la valeur de crête du champ électrique créé entre les éléments (12 et 12) et la longueur du corps vivant à vérifier est supérieur à 0,1 V. La durée d'application des impulsions de courant continu tombe dans une plage comprise entre 2 et 200 msec et le coefficient d'utilisation des impulsions de courant continu est inférieur à 0,5.
