Description

Hintergrund der ErfindungBackground of the Invention

Die Erfindung betrifft eine Überspannungsschutzeinrichtung für Signal- und Steuerleitungen, insbesondere für eine signaltechnische Einrichtung, zur Anordnung zwischen einer Außenanlage und einer Innenanlage, mit mindestens zwei Reihenklemmen, die jeweils Teil eines Signalpfads sind, wobei die Reihenklemmen Anschlusskontakte zum Anschluss an die Innen- und Außenanlage aufweisen, einer Basisklemme mit einem Anschluss für eine Ableitung zur Erde, und mindestens einem mit den Reihenklemmen elektrisch verbundenen Überspannungsschutzgerät, wobei ein Steckergehäuse vorgesehen ist, in dem das Überspannungsschutzgerät eingebaut ist.The invention relates to an overvoltage protection device for signal and control lines, in particular for a signaling device, for arrangement between an outdoor system and an indoor system, with at least two terminal blocks, which are each part of a signal path, the terminal blocks connecting contacts for connection to the indoor and outdoor system have, a base terminal with a connection for a discharge to earth, and at least one overvoltage protection device electrically connected to the terminal blocks, a connector housing being provided in which the overvoltage protection device is installed.

Eine derartige Überspannungsschutzeinrichtung ist beispielsweise aus Phoenix Contact "Netz & Signal-Qualität TRABTECH PLUGTRAB PT-IQ Intelligenter Überspannungsschutz mit System", 2013 bekannt.Such a surge protection device is known, for example, from Phoenix Contact "Network & Signal Quality TRABTECH PLUGTRAB PT-IQ Intelligent Surge Protection with System", 2013.

DE 20 2011 002 019 U1 offenbart eine Anordnung zum Öffnen einer Leitungsverbindung innerhalb eines Basisteiles, welches zur Aufnahme eines Überspannungsableiter-Steckteiles vorgesehen ist, wobei im Basisteil für mindestens eine Leitungsverbindung ein unterbrechungsfreier Schaltkontakt vorgesehen ist. DE 20 2011 002 019 U1 discloses an arrangement for opening a line connection within a base part, which is provided for receiving a surge arrester plug-in part, an uninterrupted switch contact being provided in the base part for at least one line connection.

Bahntechnische Anlagen umfassen eine Vielzahl an strombetriebenen Elementen von Außenanlagen, z.B. Bahnsingale oder Weichen, welche über Leitungen (Signalpfade) mit einer Innenanlage (z.B. einem Stellwerk, beziehungsweise der Steuerungselektronik des Stellwerks) verbunden sind. Die Körper der Außenanlagen sind zwar i.A. geerdet, dennoch kann es bspw. durch induktive Einkopplung oder Potentialdifferenzen durch Spannungstrichter, verursacht beispielsweise durch Blitzferneinschlag, zu einem Überspannungseintrag in die Steuer- und Schaltelemente (z.B. Stellwerksinnenanlage) kommen, was zu Schäden und Betriebsausfällen führen kann.Railway engineering systems include a variety of electricity-operated elements of outdoor facilities, e.g. Railway signals or switches, which are connected via lines (signal paths) to an indoor system (e.g. a signal box or the control electronics of the signal box). The bodies of the outdoor facilities are generally grounded, however, overvoltage can enter the control and switching elements (e.g. interlocking system), for example due to inductive coupling or potential differences caused by voltage funnels, e.g. caused by remote lightning strikes, which can lead to damage and breakdowns.

Um Schäden und Funktionsausfälle in Stellwerken zu vermeiden, ist es bekannt, zusätzliche Überspannungsschutzeinrichtungen zu verwenden. Die Wirkung des Überspannungsschutzes beruht auf der Ableitung auftretender Überspannungen gegen Erde.In order to avoid damage and malfunctions in signal boxes, it is known to use additional surge protective devices. The effect of the surge protection is based on the dissipation of overvoltages to earth.

Es ist bekannt, Überspannungsschutzgeräte auf Basissockel zu montieren, die über Kabelverbindungen mit Trennmessreihenklemmen verbunden sind, wie es beispielsweise von Thales Deutschland GmbH unter Verwendung von PLUGTRAB Elementen von Phoenix Contact realisiert wird.It is known to mount surge protective devices on a base base, which are connected via cable connections to isolating measuring terminal blocks, as is done, for example, by Thales Deutschland GmbH using PLUGTRAB elements from Phoenix Contact.

Nachteilig an dieser Anordnung ist, dass die Überspannungsschutzeinrichtung zusätzlich zur Trennmessreihenklemme viel Platz einnimmt und die Ableitung über eine relativ lange Strecke erfolgt, was mit hohen Ableitinduktivitäten verbunden ist, so dass beim Ableiten große Störfelder induziert werden und eine höhere Spannung an der Ableitung gegen Erde im Falle einer auftretenden Überspannung besteht.A disadvantage of this arrangement is that the overvoltage protection device takes up a lot of space in addition to the isolating measuring terminal block and the derivation takes place over a relatively long distance, which is associated with high leakage inductances, so that large interference fields are induced during discharge and a higher voltage at the discharge line to earth in If there is an overvoltage.

Zudem ist es nicht möglich, thermische Überlastungen der Überspannungsschutzgeräte zu erkennen.In addition, it is not possible to detect thermal overloads in the surge protective devices.

Die Anordnung umfasst einen Adapter zur Aufnahme des für den Einsatz im Basisteil vorgesehenen Überspannungsableiter-Steckteiles, um dieses Steckteil zu parken, wobei an einem Fußteil des Adapters ein Mittel ausgebildet ist, welches den oder die Schaltkontakte im Basisteil öffnet. DE 20 2011 002 019 U1 discloses an arrangement for opening a line connection within a base part, which is provided for receiving a surge arrester plug-in part, an uninterruptible switch contact being provided in the base part for at least one line connection and being operable by a mechanical element of the plug-in part. The arrangement comprises an adapter for receiving the surge arrester plug-in part intended for use in the base part in order to park this plug-in part, a means being formed on a foot part of the adapter which opens the switch contact or contacts in the base part.

Aufgabe der ErfindungObject of the invention

Es ist daher Aufgabe der Erfindung, eine Überspannungsschutzeinrichtung vorzuschlagen, mit der die oben genannten Nachteile vermieden werden können. Insbesondere soll die Rückwirkungsfreiheit auf dem Betrieb, sowie die signaltechnische Sicherheit der Anlage sichergestellt und gleichzeitig der Abstand zwischen Ableitpfaden gering gehalten werden.It is therefore an object of the invention to propose an overvoltage protection device with which the disadvantages mentioned above can be avoided. In particular, the freedom from interference during operation and the signaling safety of the system should be ensured and at the same time the distance between discharge paths should be kept small.

Beschreibung der ErfindungDescription of the invention

Diese Aufgabe wird erfindungsgemäß durch eine Überspannungsschutzeinrichtung gemäß Anspruch 1 gelöst.This object is achieved by an overvoltage protection device according to claim 1.

Erfindungsgemäß weisen die Reihenklemmen und die Basisklemme jeweils einen Steckplatz zum Aufstecken des Steckergehäuses des Überspannungsschutzgerätes auf, wobei die Reihenklemmen jeweils ein unverlierbares Trennmesser (z.B. schwenkbar) zur temporären Auftrennung der Signalpfade aufweisen.According to the invention, the terminal blocks and the base terminal each have a slot for plugging in the plug housing of the surge protection device, the terminal blocks each having a captive separating knife (e.g. pivotable) for temporarily separating the signal paths.

Während im Stand der Technik das Überspannungsschutzgerät auf einem gesonderten Basissockel aufgesteckt und über Kabel mit der Trennmessreihenklemme verbunden ist, sind bei der erfindungsgemäßen Überspannungsschutzeinrichtung die Trennmessreihenklemmen (Reihenklemmen mit Trennmesser) mit einem Steckplatz ausgestattet, auf dem das Überspannungsschutzgerät aufgesteckt werden kann. Erfindungsgemäß wird also der Überspannungsschutz durch direktes Aufstecken der Überspannungsschutzgeräte auf die Trennmessreihen- und Basisklemmen realisiert. Dabei werden die Anschlüsse für Einzeladern der signaltechnischen Einrichtung mit den Reihenklemmen und die Erdanschlüsse mit den Basisklemmen verbunden. Die Basisklemmen sind vorzugsweise mit Ableitfüßen ausgerüstet, die einen gasdichten und stromtragfähigen Kontakt zu einer Montageschiene, z.B. DIN-Rail Montageschiene TS 35, ermöglichen, auf der die Reihenklemmen montiert werden können.While in the state of the art the overvoltage protection device is plugged onto a separate base and connected to the isolating measurement terminal block by cable, in the overvoltage protection device according to the invention the isolating measurement terminal blocks (modular terminals with isolating knife) are equipped with a slot on which the overvoltage protection device can be attached. According to the invention Surge protection implemented by plugging the surge protective devices directly onto the isolating measuring series and basic terminals. The connections for single wires of the signaling device are connected to the terminal blocks and the earth connections to the base terminals. The base terminals are preferably equipped with discharge feet, which allow gas-tight and current-carrying contact to a mounting rail, eg DIN-Rail mounting rail TS 35, on which the terminal blocks can be mounted.

Bei der erfindungsgemäßen Überspannungsschutzeinrichtung werden also Trennmessreihenklemmen als Bindeglied, z.B. zwischen Innen- und Außenanlagenverkabelung, eingesetzt. Die für die erfindungsgemäße Überspannungsschutzeinrichtung zu verwendenden Reihenklemmen müssen daher so dimensioniert sein, dass das Überspannungsschutzgerät aufgesteckt werden kann, ohne die Anschlusskontakte zum Anschluss an die Innen- und Außenanlage zu verdecken. Darüber hinaus müssen Steckergehäuse und Steckplatz so ausgestaltet sein, dass das Überspannungsschutzgeräte stoß- und vibrationsfest gemäß EN 50125-3 verbunden werden können, dies gilt insbesondere für den gemäß EN 50125-3 definierten Bereich außerhalb der Gleise (Abstand 1-3m vom Gleis).In the overvoltage protection device according to the invention, isolating measuring series terminals are used as a link, e.g. between indoor and outdoor wiring. The terminal blocks to be used for the overvoltage protection device according to the invention must therefore be dimensioned so that the overvoltage protection device can be plugged on without covering the connection contacts for connection to the indoor and outdoor system. In addition, the connector housing and slot must be designed so that the surge protective devices can be connected in a shockproof and vibration-proof manner in accordance with EN 50125-3, this applies in particular to the area outside the tracks defined in accordance with EN 50125-3 (distance 1-3m from the track).

Bei den Anschlusskontakten der Reihenklemmen handelt es sich um Anschlüsse für Einzeladern. Auf der Seite der Außenanlage können zwar vieldrähtige Kabel verwendet werden, diese werden dann jedoch als Einzelader angeschlossen. Das erfindungsgemäße Konzept berücksichtigt, dass Adern verschiedener Stromkreise an dem gleichen Überspannungsschutzgerät angeschaltet werden können. Dies ist insbesondere für signaltechnische Anlagen wichtig, da durch diese besondere Eigenschaft die Rückwirkungsfreiheit auf die sicherheitsrelevanten Elemente der Signaltechnik erhalten bleibt.The connection contacts of the terminal blocks are connections for single wires. On the side of the outdoor system, multi-wire cables can be used, but these are then connected as a single wire. The concept according to the invention takes into account that wires of different circuits can be connected to the same surge protection device. This is particularly important for signaling systems, since this special property ensures that there is no interference with the safety-relevant elements of signaling.

Für die Verwendung der erfindungsgemäßen Überspannungsschutzeinrichtung bei signaltechnischen Einrichtungen im Bahnbetrieb müssen die verwendeten Installationskomponenten (Reihenklemme, Basisklemme) und die Überspannungsschutzgeräte für den Einsatz in Anlagen der Leit- und Sicherungstechnik zugelassen sein.For the use of the overvoltage protection device according to the invention in signaling equipment in railway operation, the installation components used (terminal block, base terminal) and the Surge protection devices must be approved for use in control and safety systems.

Mit der erfindungsgemäßen Überspannungsschutzeinrichtung können Schäden und Funktionsausfälle in Stellwerken vermieden werden, die z.B. durch Überspannungen in den Verkabelungen zu den Außenanlagen, bedingt durch Blitzferneinschläge, entstehen können. Gleichzeitig kann die erfindungsgemäße Überspannungsschutzeinrichtung platzsparend montiert werden. Vorteilhaft ist auch, dass durch die erfindungsgemäße Steckverbindung zwischen Reihenklemme und Überspannungsschutzgerät die Ableitung und die Signaldurchführung am selben Ort erfolgen, also ohne Leitungsverbindung zwischen Reihen- bzw. Basisklemme und Überspannungsschutzgerät, so dass die abzuleitende Überspannung bei geringstmöglicher Ableitinduktivität zur Erde abgeleitet werden kann. Aufgrund der kurzen Ableitwege ergeben sich geringere Beeinflussungen insbesondere durch magnetische Felder auf umgebende Komponenten.With the overvoltage protection device according to the invention, damage and malfunctions in signal boxes can be avoided, e.g. overvoltages in the cabling to the outdoor facilities, caused by remote lightning strikes. At the same time, the surge protection device according to the invention can be installed in a space-saving manner. It is also advantageous that the plug-in connection according to the invention between the terminal block and the surge protection device leads to the derivation and the signal execution at the same location, i.e. without a line connection between the terminal block or the base terminal block and the surge protection device, so that the overvoltage to be dissipated can be discharged to earth with the least possible leakage inductance. Due to the short discharge paths, there is less influence, in particular by magnetic fields on surrounding components.

Die erfindungsgemäße Überspannungsschutzeinrichtung kann auch bei anderen als bahntechnischen Anlagen zum Einsatz kommen, insbesondere bei nicht geerdeten Anlagen, da die erfindungsgemäße Überspannungsschutzeinrichtung isoliert aufgebaut ist und die enthaltenen aktiven Teile nicht berührbar sind. Vorzugsweise entspricht die erfindungsgemäße Überspannungsschutzeinrichtung mindestens den Anforderungen für die Schutzart IP 20. Ebenso ist die erfindungsgemäße Überspannungsschutzeinrichtung besonders zum Schutz für Stromkreise geeignet, bei denen die Rückwirkungsfreiheit für den Betrieb zwingend erforderlich ist.The surge protection device according to the invention can also be used in systems other than railway systems, in particular in systems which are not grounded, since the surge protection device according to the invention is constructed in an insulated manner and the active parts it contains cannot be touched. The overvoltage protection device according to the invention preferably corresponds at least to the requirements for protection type IP 20. Likewise, the overvoltage protection device according to the invention is particularly suitable for protecting circuits in which the absence of interference is absolutely essential for operation.

Die erfindungsgemäße Überspannungsschutzeinrichtung ermöglicht einen zeitversetzten Einbau verschiedener Überspannungsschutzgeräte. Dadurch können Reihen- und Basisklemmen vorinstalliert werden, so dass die Anlage auch erst einmal ohne Überspannungsschutz in Betrieb genommen werden kann und eine spätere Nachrüstung möglich ist.The surge protection device according to the invention enables a time-delayed installation of various surge protection devices. This means that terminal blocks and base terminals can be preinstalled so that the system can be started up without overvoltage protection and retrofitting is possible later.

Erfindungsgemäß umfasst das Überspannungsschutzgerät mindestens zwei Ableitpfade, wobei jeder Ableitpfad eine Reihenschaltung eines Überspannungsableiters und eines Varistors umfasst. Die Erfindung sieht also unabhängige Ableitelemente vor. Als Überspannungsableiter kann beispielsweise ein Gasableiter dienen. Mittels der Kombination von Varistor und Überspannungsableiter kann gewährleistet werden, dass es im Betrieb nicht zu Rückwirkungen der signaltechnischen Einrichtungen kommt. Darüber hinaus wird im Regelbetrieb durch das Unterbinden von Leckströmen die Alterung der Bauelemente minimiert. Insbesondere können Signalstromkreise sowie Ein-/Ausgänge, die AC- oder DC-Spannungen führen, geschützt werden. Die Kombination von Varistor und Überspannungsableiter in Reihenschaltung gewährleistet eine Unterbindung des Folgestromes.According to the invention, the surge protection device comprises at least two discharge paths, each discharge path being a series connection of a surge arrester and a varistor. The invention therefore provides independent discharge elements. A gas arrester can serve as a surge arrester, for example. The combination of varistor and surge arrester can ensure that the signaling equipment does not have any repercussions during operation. In addition, the aging of the components is minimized in normal operation by preventing leakage currents. In particular, signal circuits and inputs / outputs that carry AC or DC voltages can be protected. The combination of varistor and surge arrester in series connection prevents the follow current.

Bei der erfindungsgemäßen Überspannungsschutzeinrichtung ist zwischen den Ableitpfaden eine Barriereeinrichtung angeordnet. Die Barriereeinrichtung soll vermeiden, dass sich die die Ableitpfade berühren können, und bewirkt somit eine unverlierbare Trennung zwischen beiden Ableitpfaden. Dadurch wird die Anschaltung verschiedener Stromkreise an ein Überspannungsschutzgerät ermöglicht, wobei die Rückwirkungsfreiheit auf den Betrieb, sowie die signaltechnische Sicherheit der Anlage sichergestellt wird und gleichzeitig der Abstand zwischen den Ableitpfaden gering gehalten werden kann. Die Barriereeinrichtung verhindert die unbeabsichtigte Berührung der Komponenten der Ableitpfade und ist vorzugsweise in Form einer Isolierplatte aus einem geeigneten elektrisch isolierenden Material ausgebildet. Vorzugsweise liegt die Durchschlagfestigkeit der Barriereeinrichtung bei >10kV/mm nach Alterung. Die gemäß EN 50124-1 erforderliche Spannungsfestigkeit zwischen beiden Ableitpfaden wird durch entsprechende Dimensionierung der Luft- und Kriechstrecken sichergestellt. Durch das Vorsehen der Barriereeinrichtung können mehrere Feldelemente über dasselbe Überspannungsschutzgerät angeschlossen werden. Dies ist insbesondere dann vorteilhaft, wenn dreiadrige Feldelemente (z.B. eine Doppelfadenlampe) mit Überspannungsschutzgeräten verbunden werden sollen, die jeweils zwei Ableitpfade aufweisen, da der verbleibende Ableitpfad dann nicht frei bleiben muss, wie dies bei den aus dem Stand der Technik bekannten Überspannungsschutzeinrichtung der Fall ist, sondern für ein anderes Feldelement verwendet werden kann. Darüber hinaus kann der Planungs- und Prüfaufwand reduziert werden.In the overvoltage protection device according to the invention, a barrier device is arranged between the discharge paths. The barrier device is intended to prevent the discharge paths from touching each other, and thus results in a captive separation between the two discharge paths. This enables the connection of various circuits to an overvoltage protection device, ensuring freedom from interference with the operation and the signaling safety of the system, while at the same time keeping the distance between the discharge paths small. The barrier device prevents the accidental contact of the components of the discharge paths and is preferably designed in the form of an insulating plate made of a suitable electrically insulating material. The dielectric strength of the barrier device is preferably> 10 kV / mm after aging. The required dielectric strength between the two discharge paths according to EN 50124-1 is ensured by appropriate dimensioning of the air and creepage distances. By providing the barrier device, several field elements can be connected via the same surge protection device. This is particularly advantageous when three-wire field elements (e.g. a double filament lamp) are to be connected to surge protection devices, each of which has two discharge paths, since the remaining discharge path does not then have to remain free, as is the case with the surge protection device known from the prior art but for a different field element can be used. In addition, the planning and testing effort can be reduced.
