Description
HINTERGRUND DER ERFINDUNGBACKGROUND OF THE INVENTION
Die vorliegende Erfindung betrifft eine DC-(Gleichstrom)-Stromerkennungs- und Schutzvorrichtung, insbesondere eine automatische DC-Stromerkennungsvorrichtung mit einer Schutzschaltung zur Vermeidung von Überspannungen und Überströme, und die auch die verschiedenen Zustände anzeigt, um Störungen und Fehler des Systems vorzubeugen.The The present invention relates to a DC (direct current) current detection and protection device, in particular an automatic DC current detection device with a protection circuit to prevent overvoltages and overcurrents, and which also the different states indicating to interference and to prevent system errors.
Gleichsstromquellen kommen häufig in der Industrie und im Alltagsleben zur Anwendung. Der Wechselstrom wird dabei in Gleichstrom umgewandelt. Um eine Überlastung eines Gleichstromnetzes zu vermeiden, wird eine Erkennungsschaltung für das optimale Einstellen dieses Systems benötigt. Mit der vorliegenden Erfindung soll eine automatische Gleichstromerkennungsvorrichtung zum Schutz gegen Überspannungen und Überströme geschaffen werden, das sich zum Vermeiden einer Überspannung sowie eines Überstromes eignet für den Fall, wenn der Benutzer es versäumt, eine Stromlast auszuschalten, oder für den Fall einer abnormalen Funktion von Generatoren, eines Verkehrsunfalls oder eines Kurschlusses usw.DC sources come often used in industry and in everyday life. The alternating current is converted into direct current. To overload a DC network too avoid, will provide a detection circuit for optimally setting this Systems needed. The present invention is an automatic DC detection device for protection against overvoltages and overflows are created this is to avoid overvoltage as well as an overcurrent suitable for the case when the user fails to turn off a power load, or for the case of an abnormal function of generators, a traffic accident or a short-circuit, etc.
