Abstract

Electroaimant à courant sinusoïdal très basse tension (TBT) alimenté par batterie. L'invention consiste en une solution autonome et portable sans risque électrique pour son utilisateur. Constitué d'une électronique (1) intégrant un microcontrôleur pour générer des signaux carrés à variation de cycle, un circuit de puissance et un étage de filtrage. Le signal sinusoïdal issu du filtre est connecté au solénoïde (2) enroulé autour de l'âme métallique (3) constitutif de l'électroaimant. L'interrupteur (5) pilote le circuit de puissance par le biais d'une chaine de sécurité thermique et électronique. L'ensemble est intégré dans une poignée (4) et alimenté via le câble (6) par une batterie externe standard de type outillage électroportatif généralement portée à la ceinture de l'opérateur. L'électroaimant selon l'invention est particulièrement destiné aux contrôles non destructifs par magnétoscopie.Very low voltage (VLV) sinusoidal current electromagnet powered by battery. The invention consists of an autonomous and portable solution without electrical risk for its user. Consisting of electronics (1) integrating a microcontroller to generate cycle-varying square signals, a power circuit and a filter stage. The sinusoidal signal from the filter is connected to the solenoid (2) wound around the metal core (3) constituting the electromagnet. The switch (5) controls the power circuit via a thermal and electronic safety chain. The assembly is integrated into a handle (4) and powered via the cable (6) by a standard external battery of the power tool type generally carried on the operator's belt. The electromagnet according to the invention is particularly intended for non-destructive magnetic particle testing.
