Title
(EN) PUMPING UNIT WITH VERY LOW VOLTAGE THREE-PHASE MOTOR
(FR) GROUPE DE POMPAGE A MOTEUR TRIPHASE TRES BASSE TENSION
Abstract
(EN)
In this pumping unit, the motor (1) is supplied with a very low security voltage and the supply circuit comprises successively from the source (2) to the motor (1), a frequency converter (3) and a three-phase transformer (9).
(FR)
Dans ce groupe de pompage, le moteur (1) est alimenté en très basse tension de sécurité et le circuit d'alimentation comprend successivement de la source (2) au moteur (1), un convertisseur (3) de fréquence et un transformateur (9) triphasé.
