Title
(DE) SCHALTUNGSANORDNUNG ZUR ANSTEUERUNG WENIGSTENS EINES ELEKTRISCH ANSTEUERBAREN MAGNETEN
(EN) CIRCUIT FOR THE DRIVE OF AT LEAST ONE ELECTRICALLY ACTUATED MAGNET
(FR) CIRCUITERIE D'EXCITATION D'AU MOINS UN AIMANT A EXCITATION ELECTRIQUE
Abstract
(DE)
Bei einer Schaltungsanordnung zur Ansteuerung wenigstens eines elektrisch ansteuerbaren Magneten mit einer zielgerichteten Ansteuerleistung, durch welche der Magnet ein Schaltglied in eine gewünschte Schaltposition schaltet, in welcher das Schaltglied gehalten ist, ist der Magnet nach seinem Umschalten des Schaltgliedes in die gewünschte Schaltposition in vorbestimmten Zeitintervallen wiederholt mit zu dieser Schaltposition korrespondierender Ansteuerleistung wenigstens kurzfristig beaufschlagt.
(EN)
The invention concerns a circuit for the drive of at least one electrically actuated magnet by means of an appropriately sized actuation power which causes the magnet to switch a switching element into the desired position where it is held in place. After the switching element has been switched into the desired position, the magnet is repeatedly acted on at predetermined time intervals, at least for a short period, by the actuation power corresponding to this switch position.
(FR)
L'invention concerne une circuiterie qui permet d'exciter au moins un aimant à excitation électrique, avec une puissance d'excitation ciblée, grâce à laquelle l'aimant commute un élément de commutation dans la position de commutation voulue, dans laquelle l'élément de commutation est maintenu. Après commutation de l'élément de commutation dans la position de commutation voulue, l'aimant est à nouveau sollicité à intervalles prédéfinis, au moins à court terme, par la puissance d'excitation correspondant à cette position de commutation.
