VLT® Low Harmonic Drives - Netzqualität erhalten

Vorteile aktiver Filter und drehzahlgeregelter Antriebe vereint

(PresseBox) (Hannover, )
Frequenzumrichter verhalten sich gegenüber dem speisenden Netz nicht neutral. Die Gleichrichterbrücken laden die in den Geräten enthaltenen Energiespeicher, wie Zwischenkreiskondensatoren, kontinuierlich nach. Dies führt zu einem stoßförmigen Ladestrom an Stelle eines kontinuierlichen Stromflusses. Die Folge sind Oberschwingungen oder Harmonische, die ins speisende Netz zurückgegeben werden und dessen Qualität negativ beeinflussen. Um diese Effekte bei seinen Frequenzumrichtern weiter zu reduzieren, stellt Danfoss im Bereich der High Power Drives die VLT® Low Harmonic Drives vor. Sie vereinen die Vorteile des aktiven Filters mit denen des drehzahlgeregelten Antriebs in idealer Weise. Die integrierten, optimal angepassten aktiven Filter eliminieren die durch den Frequenzumrichter hervorgerufenen
