Abstract
Description
Es ist bekannt, dass schädliche Überspannungen
Bei elektrischen Leitungen, die der Übermittlung von Signalen dienen, führt der Schutz vor Überspannungen zu einem Zielkonflikt zwischen Kriterien, welche die Schutzwirkung beschreiben, einerseits und der nicht beabsichtigten Beeinflussung des zu übertragenden Signals im ungefährdeten Betrieb andererseits.In the case of electrical lines which serve to transmit signals, the protection against overvoltages leads to a conflict of objectives between criteria which describe the protective effect, on the one hand, and the unintentional influence on the signal to be transmitted during safe operation, on the other hand.
Das zu übertragende Signal kann im überpannungsfreien Normalbetrieb unbeabsichtigt gedämpft werden durch den Wirkleitwert oder Blindleitwert des Schutzelements
Wenn die Leitwerte des Schutzelements nicht konstant sind, sondern von der anliegenden Spannung abhängen, der Zusammenhang zwischen dem Strom durch das Schutzelement und die Spannung über dem Schutzelement also nichtlinear ist, kann das Schutzelement in Verbindung mit der umgebenden Beschaltung unbeabsichtigt Oberwellen oder Intermodulationsprodukte der im zu übertragenden Signal enthaltenen Frequenzen verursachen.If the conductivities of the protection element are not constant, but depend on the applied voltage, that is, the relationship between the current through the protection element and the voltage across the protection element is non-linear, the protection element in conjunction with the surrounding circuitry may inadvertently create harmonics or intermodulation products cause transmitted signals.
Im ungestörten Betrieb sind Funkenstrecken frei von Nichtlinearitäten. Der Leitwert wird durch die Kapazität zwischen den Elektroden bestimmt. Je kleiner diese Kapazität ist, umso größer ist der Frequenzbereich, im welchem der kapazitive Blindstrom für die technische Anwendung nicht relevant ist. Diese Eigenschaften prädestinieren Funkenstrecken als Schutzelemente für signalübertragende elektrische Leitungen.In undisturbed operation, spark gaps are free of nonlinearities. Conductance is determined by the capacitance between the electrodes. The smaller this capacitance is, the larger the frequency range in which the capacitive reactive current is not relevant for the technical application. These properties predestine spark gaps as protective elements for signal-transmitting electrical lines.
Nachteilig ist jedoch erstens, dass Funkenstrecken nur für Ansprechspannungen ab 90 V handelsüblich sind.The disadvantage, however, first, that spark gaps are commercially available only for threshold voltages from 90 V.
Nachteilig ist zweitens, dass die tatsächliche Ansprechspannung bei impulsförmigen Überspannungen wesentlich über den angegebenen Nennwerten der Ansprechspannung liegt, so kann eine Funkenstrecke mit einer Nennansprechspannung von 90 V bei realistischen impulsförmigen Überspannungen erst bei mehreren 100 V ansprechen [1].Secondly, it is disadvantageous that the actual response voltage for pulse-like overvoltages is significantly above the specified nominal values of the response voltage, so a spark gap with a nominal response voltage of 90 V can only respond to several 100 V at realistic impulse-type overvoltages [1].
Eine Lösung des zweiten Problems liegt wie in
Exemplarisch kann das System mit einer handelsüblichen symmetrischen Funkenstrecke nach ITU K12 [2] aufgebaut werden. Das Verzögerungsglied muss das Signal mindestens um den internen Verzug zwischen beiden Teilfunkenstrecken verzögern, der nach [2] bis zu 200 ns betragen kann.As an example, the system can be constructed with a commercially available symmetrical spark gap according to ITU K12 [2]. The delay element must delay the signal at least by the internal delay between the two partial spark gaps, which can be up to 200 ns after [2].
Der Überspannungsableiter kann dämpfungsarm realisiert werden mit einer Leitung als Verzögerungsglied, deren Mindestlänge 40 m beträgt.The surge arrester can be realized with low attenuation with a line as a delay element whose minimum length is 40 m.
Eine kompaktere, in Geräte integrierbare, aber stärker dämpfende und als Tiefpass wirkende Anordnung ist mit einer Induktivität anstelle der Verzögerungsleitung realisierbar.A more compact, device-integrated, but more strongly attenuating and low-pass arrangement can be realized with an inductance instead of the delay line.
Die Tiefpasswirkung einer Induktivität als Verzögerungsglied kann durch eine passive Allpass-Schaltung gemäß
