Abstract
Description
Die Erfindung betrifft einen Überspannungsschutz für eine Spannungsversorgung.The The invention relates to overvoltage protection for one Power supply.
Schaltungen für einen Überspannungsschutz sind allgemein bekannt. Es werden einzelne Varistoren im Spannungsnetz angeordnet, die über eine geeignete Verdrahtung mit einem Filter verbunden sind, welcher zur Entkopplung zwischen einem Grobschutz und einem ausgangsseitig vorgesehenen Feinschutz dient.circuits for overvoltage protection are well known. There are individual varistors in the voltage network arranged over a suitable wiring are connected to a filter, which for Decoupling between a coarse protection and an output side provided Fine protection is used.
In der Praxis hat sich herausgestellt, daß derartige Überspannungsschutzschaltungen problematisch sind, da durch die diskreten Verdrahtungen zum Filter die Sperrwirkung unkontrolliert beeinflußt wird.In In practice, it has been found that such overvoltage protection circuits are problematic, because through the discrete wiring to the filter the blocking effect is influenced uncontrollably.
Der Erfindung liegt die Aufgabe zugrunde, einen Überspannungsschutz für eine Spannungsversorgung anzugeben, die über eine weite Bandbreite eine gute Sperrwirkung gegen Überspannungen jeder Art aufweist.Of the Invention is based on the object, an overvoltage protection for a power supply indicate that over a wide bandwidth a good barrier against overvoltages of every kind.
Die Aufgabe wird nach den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The The object is achieved by the characterizing features of claim 1 solved.
Die aus einem eingangsseitigen Grobschutz und einem ausgangsseitigen Feinschutz sowie einer zwischen dem Grobschutz und dem Feinschutz angeordneten Entkopplung bestehende Schutzschaltung zeichnet sich dadurch aus, daß die Bauelemente des Grobschutzes, die Bauelemente des Feinschutzes und die Bauelemente der Entkopplung eng benachbart auf einem gemeinsamen Bauteileträger in einem gemeinsamen Gehäuse angeordnet sind.The from an input coarse protection and an output side Fine protection as well as one between the coarse protection and the fine protection arranged decoupling existing protection circuit is characterized in that the Components of coarse protection, the components of fine protection and the components of the decoupling closely adjacent to a common Component carrier in a common housing are arranged.
Aufgrund der engen Anordnung der Bauteile zueinander werden Leitungsinduktivitäten vermieden und damit eine Beeinträchtigung des verwendeten Filters weitgehend eliminiert. Die Anordnung in einem gemeinsamen Gehäuse schirmt die Schutzschaltung gegen äußere Einflüsse, insbesondere EMV-Einflüsse ab, so daß eine fehlerfreie Funktion auch unter schwierigen Einsatzbedingungen gewährleistet ist.by virtue of the close arrangement of the components to each other Leitungsinduktivitäten be avoided and thus an impairment the filter used largely eliminated. The arrangement in a common housing shields the protective circuit against external influences, in particular EMC influences, so that one error-free operation guaranteed even under difficult operating conditions is.
In der Praxis hat sich gezeigt, daß aufgrund der eng benachbart angeordneten Bauteile ohne Funktionsbeeinträchtigung eine hervorragende Schutzwirkung erzielt wird.In Practice has shown that due to the closely adjacent arranged components without functional impairment an excellent protective effect is achieved.
Die Bauteile des Grobschutzes und des Filters und/oder des Feinschutzes und des Filters, zweckmäßig alle Bauteile des Überspannungsschutzes, sind auf dem insbesondere als Platine mit Leitungsbahnen ausgebildeten Bauteileträger mit geringem Abstand voneinander angeordnet, wobei als geringer Abstand ein Abstand von weniger als 10 mm, vorzugsweise weniger als 5 mm zwischen den Bauteilen verstanden wird.The Components of the coarse protection and the filter and / or the fine protection and the filter, all appropriate Components of the overvoltage protection, are formed on the particular as a circuit board with conductor paths component support arranged at a small distance from each other, being less Distance a distance of less than 10 mm, preferably less is understood as 5 mm between the components.
Zur elektromagnetischen Abschirmung ist das Gehäuse aus einem elektrisch leitfähigen Material gebildet, insbesondere als Aluminiumgehäuse ausgebildet.to Electromagnetic shield is the housing made of an electrically conductive material formed, in particular designed as an aluminum housing.
Vorteilhaft besteht der Grobschutz aus Varistoren, wobei ein Varistor über einen Überspannungsableiter mit dem Erdleiter verbunden ist. Zweckmäßig sind beide Varistoren des Grobschutzes über einen gemeinsamen Überspannungsableiter mit der Erde verbunden, wobei über den Überspannungsableiter der Grobschutz galvanisch vom Erdleiter getrennt ist. Zweckmäßig wird hierzu als Überspannungsableiter ein gasgefüllter Überspannungsableiter verwendet.Advantageous the coarse protection consists of varistors, whereby a varistor has a surge arrester connected to the ground wire. Appropriately, both varistors of the Rough protection over a common surge arrester being connected to the earth, being over the surge arrester the coarse protection is galvanically isolated from the earth conductor. It is useful for this purpose as a surge arrester a gas-filled surge arrester used.
Die Entkopplung zwischen dem Grobschutz und dem Feinschutz ist als Filter ausgebildet, der als Gleichtaktfilter, Gegentaktfilter bzw. Tiefpaßfilter gestaltet sein kann. Ein derartiger Filter besteht aus einer in jeder Leitung angeordneten Reihenschaltung aus einer Induktivität und einem ohmschen Widerstand, sowie aus einem zwischen den Leitungen der Phase angeschlossenen Kondensator. Die Induktivitäten sind zweckmäßig als Längsspulen ausgebildet, während die ohmschen Widerstände jeweils als Spule mit einem Eisenkern ausgebildet sind.The Decoupling between the coarse protection and the fine protection is as a filter designed as a common mode filter, push-pull filter or low-pass filter can be designed. Such a filter consists of an in each line arranged series connection of an inductance and a ohmic resistance, as well as one between the lines of the phase connected capacitor. The inductors are useful as longitudinal coils trained while the ohmic resistances are each formed as a coil with an iron core.
