Get Alternatives Energiekonzept zur Stromversorgung am PDF

By Oliver Richard Neubert

ISBN-10: 3842858175

ISBN-13: 9783842858176

Mit der Einführung der elektronischen Bahnübergangsicherungsanlagen konnte ein wichtiger Meilenstein in der Verwirklichung moderner Technik am Bahnübergang gesetzt werden. Zur Sicherstellung des technischen Fortschrittes unterliegt dieses procedure einer ständigen Weiterentwicklung. So konnten zum Beispiel in den letzten Jahren erfolgreich LED Signalgeber eingeführt werden.
Befinden sich BÜSA kurz hintereinander spricht guy von Bahnübergangsketten. In Bahnübergangsketten wird für jeden Bahnübergang eine eigene Schalteinrichtung mit Schalthaus, Batterie und Energieversorgungsanschluss benötigt. Zur Reduzierung dieser Kosten kann es sinnvoll sein, die Bahnübergangsanlagen in einer Kette in einem zentralen Schalthaus zu integrieren.
Die Integration der Schalteinrichtung stösst sehr schnell an ihre Grenze, da die Schrankenantriebe während des Schaltvorgangs kurzzeitig viel Energie benötigen und mit der heute eingesetzten Technik die Übertragungsstrecke limitiert ist.
Zum Speichern von Energie werden Doppelschichtkondensatoren verwendet. Die Forschung und Entwicklung von Doppelschichtkondensatoren ist mittlerweile so weit fortgeschritten, dass sich für diese Energiespeicher interessante Einsatzmöglichkeiten, auch in der Eisenbahntechnik, ergeben.
Es wäre denkbar, die Steuereinrichtung für mehrere Bahnübergänge in einem Schalthaus zu integrieren, obwohl die Bahnübergänge in weiteren Entfernungen auseinander liegen.
Die vorliegende Studie zeigt anhand von theoretischen Betrachtungen Möglichkeiten für den Einsatz von Doppelschichtkondensatoren auf. Hierbei werden insbesondere die planungstechnischen Parameter betrachtet.Oliver Neubert wurde 1980 in Hagen (Westf.) geboren. Nach seiner Berufsausbildung zum Energieelektroniker Anlagentechnik in einem grossen Infrastrukturunternehmen lernte er die Leit- & Sicherungstechnik als Angestellter in diesem Bereich kennen. Neben dem Beruf entschied sich Oliver Neubert seine Kenntnisse durch ein Studium zu erweitern und schloss dieses im Jahre 2010 an der Wilhelm Büchner Hochschule (Private Fernfachhochschule Darmstadt) mit dem akademischen Grad des Diplom Ingenieurs erfolgreich ab.
