Title
(DE) VERFAHREN ZUR BEGRENZUNG EINES ELEKTRISCHEN STROMS DURCH EIN ELEKTRISCHES BAUTEIL UND BEGRENZUNGSVORRICHTUNG
(EN) METHOD FOR LIMITING AN ELECTRIC CURRENT PASSING THROUGH AN ELECTRICAL COMPONENT AND LIMITING DEVICE
(FR) PROCEDE POUR LIMITER UN COURANT ELECTRIQUE PASSANT A TRAVERS UN COMPOSANT ELECTRIQUE ET DISPOSITIF LIMITEUR
Abstract
(DE)
Zur Begrenzung eines elektrischen Stromes (I) durch ein elektrisches Bauteil (76), insbesondere die Läuferwicklung eines Turbogenerators, wird die thermische Belastung (b) des Bauteils (76) zugrunde gelegt. Damit wird sicher eine Überhitzung des Bauteils (76) vermieden und gleichzeitig eine volle Ausschöpfung des elektrischen Stromes (I), insbesondere bei einer Stoßerregung, erreicht.
(EN)
In order to limit the electrical current (I) passing through an electrical component (76), especially the rotor winding of a turbogenerator, the thermal load (b) of the component (76) is taken as a basis. This reliably prevents overheating of the component (76) and full evacuation of the electrical current (I) is simultaneously achieved, especially in case of shock excitation.
(FR)
Afin de limiter un courant électrique (I) passant à travers un composant électrique (76), notamment l'enroulement rotorique d'un turbogénérateur, il est prévu de se fonder sur la charge thermique (b) du composant (76). Ce qui permet d'éviter en toute fiabilité une surchauffe du composant (76) et de parvenir simultanément à vider complètement le courant électrique (I), notamment en cas d'excitation par choc.
