Description

Die Erfindung bezieht sich auf einen Schaltpol für ein Hochspannungsnetz der im Oberbegriff von Patentanspruch 1 angegebenen Art.The invention relates to a switching pole for a high-voltage network specified in the preamble of claim 1. Art.

Ein derartiger Schaltpol ist z.B. in der US 5729888 bereits offenbart, wobei die Schalteinrichtung im Schaltpolgehäuse eine Vakuumschaltröhre ist. Diese Vakuumschaltröhre ist in einer oberen Hohlkammer des in montiertem Zustand stehend angeordneten Schaltpolgehäuses angebracht, wobei die Festkontaktseite oben und die Bewegkontaktseite unten liegt. Auf der Festkontaktseite ist der Festkontakt der Vakuumschaltröhre leitend mit einem Eingangsanschlussstück verbunden, das koaxial zur Mittellängsachse des Schaltpolgehäuses verläuft und mit einem zum Leitungsanschluss dienenden Gewindestück aus dem oberen Ende des Gehäuses heraussteht. Am unteren Ende ragt aus der Vakuumschaltröhre ein Führungsrohr heraus, das mit dem beweglichen Kontakt der Schaltröhre gekoppelt ist und eine Mittelöffnung in einem topfförmigen Sammelring eines seitlich aus dem Gehäuse herausstehenden Abgangsanschlussstücks durchsetzt. Der Bewegkontakt ist unter axialer Koppelung mit einer isolierten Schaltstange verbunden, die im oberen Endbereich ständig leitend mit dem Abgangsanschlussstück verbunden ist. Zum Ein- bzw. Ausschalten der Schaltröhre lässt sich die Schaltstange z.B. durch einen Nockenmechanismus nach oben bzw. unten verstellen, wobei die Kontakte der Vakuumschaltröhre aufeinandergedrückt bzw. auseinanderbewegt werden. Zur laufenden Überwachung des Schaltzustandes bzw. des Betriebs sind am Schaltpolgehäuse ein Stromsensor und ein Spannungssensor angeordnet. Der ringförmige Stromsensor umschließt das Eingangsanschlussstück und ist somit im oberen Endbereich des Schaltpolgehäuses angeordnet. Demgegenüber ist der stabförmige Spannungssensor unterhalb des seitlich im Mittelbereich des Schaltpolgehäuses angeordneten Abgangsanschlussstücks in die Rohrwand integriert, welche den unteren Längenbereich der Hohlkammer an ihrem Umfang begrenzt.Such a switching pole is eg in the US 5729888 already disclosed, wherein the switching device in Schaltpolgehäuse is a vacuum interrupter. This vacuum interrupter is mounted in an upper hollow chamber of the standing in the assembled state arranged Schaltpolgehäuses, the fixed contact side is above and the Bewegkontaktseite down. On the fixed contact side of the fixed contact of the vacuum interrupter is conductively connected to an input terminal which is coaxial with the central longitudinal axis of the Schaltpolgehäuses and protrudes with a serving for line connection threaded piece from the upper end of the housing. At the lower end protrudes from the vacuum interrupter, a guide tube which is coupled to the movable contact of the interrupter and passes through a central opening in a cup-shaped collecting ring of a laterally protruding from the housing outlet connection piece. The moving contact is connected under axial coupling with an insulated switching rod, which is constantly connected in the upper end region in a conductive manner with the outgoing connecting piece. To turn on or off the interrupter, the shift rod can be adjusted for example by a cam mechanism up or down, the contacts of the vacuum interrupter are pressed together or moved apart. For continuous monitoring of the switching state or the operation, a current sensor and a voltage sensor are arranged on the switching pole housing. The annular current sensor encloses the input terminal and is thus arranged in the upper end of the Schaltpolgehäuses. In contrast, the rod-shaped voltage sensor below the laterally arranged in the central region of the Schaltpolgehäuses outlet fitting is integrated into the tube wall, which limits the lower length of the hollow chamber at its periphery.

Ein anderes Beispiel von Schaltpol wird in WO-A-9527297 offenbart.Another example of switching pole is in WO-A-9527297 disclosed.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Schaltpol der im Oberbegriff von Patentanspruch 1 angegebenen Art mit einer hohen Durchschlagsicherheit bei einer kombinierten Anordnung von Strom- und Spannungssensor anzugeben.The invention is therefore an object of the invention to provide a switching pole specified in the preamble of claim 1 type with a high breakdown safety in a combined arrangement of current and voltage sensor.

Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen von Patentanspruch 1.The solution of this problem arises from the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Der Schaltpol für ein Hochspannungsnetz umfasst ein Schaltpolgehäuse aus festem Isolierstoff, in dem eine Schalteinrichtung mit Fest- und Bewegkontakt angeordnet ist, deren Bewegkontakt über den richtungsumkehrbaren Vorschub einer Schaltstange zwischen der ein- und der ausgeschalteten Stellung bewegbar ist, wobei in der Einschaltstellung mittels der Schalteinrichtung ein Eingangsanschlussstück auf der Festkontaktseite elektrisch leitend mit einem Abgangsanschlussstück auf der Bewegkontaktseite verbunden ist. Der Schaltpol umfasst darüber hinaus eine Sensoranordnung, die einen Strom- und einen Spannungssensor aufweist. Erfindungsgemäß sind der Stromsensor und der Spannungssensor an der Umfangswand des Schaltpolgehäuses an einem zugeordneten Anschlussstück angeschlossen, wobei der Stromsensor in einem Teilentladungen verhindernden Umfangsabstand zum Spannungssensor an der Umfangswand des Schaltpolgehäuses angeordnet ist.The switching pole for a high voltage network comprises a Schaltpolgehäuse of solid insulating material, in which a switching device is arranged with fixed and moving contact whose moving contact on the direction reversible feed a shift rod between the on and the off position is movable, wherein in the closed position by means of the switching device an input terminal on the fixed contact side is electrically conductively connected to an outgoing terminal on the Bewegkontaktseite. The switching pole furthermore comprises a sensor arrangement which has a current and a voltage sensor. According to the invention, the current sensor and the voltage sensor are connected to the peripheral wall of the switching pole housing at an associated connection piece, wherein the current sensor is arranged in a partial discharge preventing circumferential distance to the voltage sensor on the peripheral wall of the Schaltpolgehäuses.

Durch die gemeinsame Anordnung von Strom- und Spannungssensor an einem der Anschlussstücke, insbesondere am Abgangsanschlussstück, kann bei ausgeschalteter Vakuumschaltröhre z. B. ein Kurzschluss im an das Abgangsanschlussstück angeschlossenen Netzbereich festgestellt werden. Dabei liegen das Hochspannungspotential des Spannungssensors und das Erdpotential des Stromsensors insbesondere durch den zwischen den Sensoren vorgesehenen Umfangsabstand räumlich derart auseinander, das inhomogene Feldverläufe und örtliche Überschreitungen der Durchschlagfeldstärke des Isoliermaterials und somit Teilentladungen sicher vermieden sind. Mit anderen Worten: Die gleichzeitig an eines der Anschlussstücke des Schaltpols angeschlossenen Strom- und Spannungssensoren sind derart zueinander beabstandet und an die Umfangswand angeordnet, dass eine hohe Durchschlagsicherheit der Isolierung sichergestellt ist.Due to the common arrangement of current and voltage sensor on one of the fittings, in particular at the outlet connection piece, with switched off the vacuum interrupter z. B. a short circuit in the connected to the outgoing connector network area are detected. In this case, the high voltage potential of the voltage sensor and the ground potential of the current sensor in particular spatially so far apart by the provided between the sensors circumferential distance, the inhomogeneous field courses and local exceedances of the breakdown field strength of the insulating material and thus partial discharges are avoided. In other words, the current and voltage sensors connected at the same time to one of the connecting pieces of the switching pole are spaced apart from one another and arranged on the peripheral wall in such a way that a high breakdown safety of the insulation is ensured.

Der dem Anschlussstück zusätzlich zugeordnete Spannungssensor oder Stromsensor kann ggf. der vom anderen Anschlussstück verlegte Spannungssensor bzw. Stromsensor sein. Alternativ kann aber auch beiden Anschlussstücken ein Spannungssensor oder ein Stromsensor zugeordnet werden, falls die Strommessung weiterhin auch am anderen Anschlussstück erfolgen soll.The voltage sensor or current sensor additionally assigned to the connection piece may optionally be the voltage sensor or current sensor installed by the other connection piece. Alternatively, however, a voltage sensor or a current sensor can also be assigned to both connecting pieces if the current measurement should continue to be carried out on the other connecting piece as well.

Durch die erfindungsgemäße Anordnung der Sensoren wird erreicht, dass die an einem gemeinsamen Anschlussstück anliegenden Potentiale von Spannungs- und Stromsensor räumlich besser ausgesteuert bzw. abgesteuert werden. Wegen des Versatzes in Umfangsrichtung des Schaltpolgehäuses ergibt sich neben der räumlichen Entzerrung der Sensoren unweigerlich auch eine feldtechnische Optimierung des dem Anschlussstück zugeordneten Sensorpaars.As a result of the arrangement of the sensors according to the invention, it is achieved that the potentials of the voltage and current sensors applied to a common connection piece are spatially better controlled or deactivated. Because of the offset in the circumferential direction of the Schaltpolgehäuses results in addition to the spatial equalization of the sensors inevitably also a field-technical optimization of the connector associated sensor pair.

Wenn der Schaltpol nur mit einem Spannungs- und einem Stromsensor versehen ist, lassen sich diese Sensoren vorzugsweise um 180 Grad oder in einem anderen vorgebbaren Winkel versetzt am Umfang des Schaltpolgehäuses anordnen, was im Hinblick auf die Vermeidung von Teilentladungen besonders sicher ist.If the switching pole is provided with only one voltage and one current sensor, these sensors can preferably be arranged at 180 degrees or at a different predeterminable angle on the circumference of the switching pole housing, which is particularly safe in terms of avoiding partial discharges.

Falls dieser Umfangsversatz von 180 Grad nicht möglich ist, sollte der Stromsensor gegenüber dem Spannungssensor um einen Winkel von mindestens 90 Grad versetzt an der Umfangswand des Schaltpolgehäuses angeordnet sein. Hierdurch kann bei Schaltpolen unter in Hochspannungsnetzen üblichen Bedingungen noch eine TE-freie Anordnung (TE= Teilentladungen) des Sensorpaars erreicht werden. Dieser Umfangsversatz um einen Winkel von 90 Grad lässt sich selbst dann noch einhalten, wenn der Schaltpol an seiner Umfangswand neben dem Stromsensor noch zwei Spannungssensoren aufweist, die diametrisch angeordnet sind.If this circumferential offset of 180 degrees is not possible, the current sensor should be arranged offset relative to the voltage sensor by an angle of at least 90 degrees on the peripheral wall of the Schaltpolgehäuses. As a result, it is possible to achieve a TE-free arrangement (TE = partial discharges) of the sensor pair in switching poles under conditions which are usual in high-voltage networks. This circumferential offset by an angle of 90 degrees can be maintained even if the switching pole next to the current sensor has two voltage sensors on its peripheral wall, which are arranged diametrically.

Aufgrund ihrer länglichen Form lässt sich der Spannungssensor oder lassen sich die beiden Spannungssensoren z.B. durch Einbetten bzw. Eingießen jeweils in einen zugeordneten Bereich der Umfangswand des Schaltpols integrieren. Vorteilhaft werden die Spannungssensoren dabei so angebracht, dass die konstruktiv festgelegte Isolationswanddicke des Schaltpolgehäuses auch zwischen Sensor und Hohlraum gegeben ist.Due to its elongated shape, the voltage sensor can be let or the two voltage sensors can be used e.g. by embedding or pouring respectively in an associated area of the peripheral wall of the Schaltpols integrate. Advantageously, the voltage sensors are mounted so that the structurally defined insulation wall thickness of the Schaltpolgehäuses is also given between the sensor and cavity.

Um dies bei möglichst geringer und gleichmäßiger Wanddicke des Schaltpolgehäuses zu ermöglichen, sind die Spannungssensoren jeweils in einen Gehäusesteg integriert, der tunnelartig erhaben entlang dem Außenumfang des Gehäuses verläuft. Vorzugsweise ist die Länge des Gehäusestegs dabei so bemessen, dass auch die angeschlossene Sensorleitung mit einem Längenabschnitt in den Gehäusesteg integriert sein kann. Wenn das Anschlussstück mit dem Sensorenpaar radial vom Schaltpol absteht, lässt sich der Stromsensor vorzugsweise in einem Abstand zur Umfangswand des Schaltpols in ein das Anschlussstück isolierendes Abzweigrohr des Schaltpolgehäuses integrieren. Die zugehörige Sensorleitung des Stromsensors kann dabei vorteilhaft in einen weiteren erhabenen Gehäusesteg integriert sein, der vom Abzweigrohr zum Fuß des Schaltpols verläuft.To enable this with the smallest possible and uniform wall thickness of the Schaltpolgehäuses, the voltage sensors are each integrated in a housing bar, which extends tunnel-like raised along the outer circumference of the housing. Preferably, the length of the housing web is dimensioned such that the connected sensor line can be integrated with a longitudinal section in the housing web. If the connection piece projects radially from the switching pole with the pair of sensors, the current sensor can preferably be integrated at a distance from the peripheral wall of the switching pole into a branching tube of the switching pole housing insulating the connecting piece. The associated sensor line of the current sensor can be advantageously integrated into a further raised housing web, which runs from the branch pipe to the foot of the Schaltpols.

In zum Gehäusesteg ähnlicher Weise kann auch die Sensorleitung des Spannungssensors in einem durch den Versatz zum Stromsensor bedingten Umfangsabschnitt in einen Ringwulst des Schaltpolgehäuses integriert sein, der sich unter etwa viertelkreisförmiger Krümmung zwischen dem Gehäusesteg des Spannungssensors und dem Abzweigrohr erstreckt.In a manner similar to the housing web, the sensor line of the voltage sensor can be integrated in an annular section of the switching pole housing in a peripheral section caused by the offset to the current sensor, which extends under approximately quarter-circle curvature between the housing web of the voltage sensor and the branch pipe.

Vorzugsweise ist der Spannungssensor über eine etwa rechtwinklig abgebogene Sensorleitung an das Hochspannungspotential der Bewegkontaktseite angeschlossen. Die Sensorleitung kann dabei aus einer Litze bestehen, die in einem unter einem Winkel von 90 Grad abgebogene Schutzrohr geführt ist. Alternativ kann die Sensorleitung des Spannungssensors aus einem entsprechend abgebogenen Drahtleiter bzw. Drahtbügel bestehen.Preferably, the voltage sensor is connected via an approximately bent at right angles sensor line to the high voltage potential of the Bewegkontaktseite. The sensor line can consist of a strand, which is guided in a bent at an angle of 90 degrees protective tube. Alternatively, the sensor line of the voltage sensor may consist of a correspondingly bent wire conductor or wire bracket.

Eine möglichst gleichmäßige Wanddicke des Schaltpolgehäuses mit erhabener Einbettung von Sensoren und ggf. Sensorleitungen wirkt sich vorteilhaft auf den Materialverbrauch bei der Herstellung des Gehäuses aus. Zudem kann die Wärmeabfuhr bei starker Wärmebelastung des Schaltpols problemloser erfolgen.The most uniform possible wall thickness of the Schaltpolgehäuses with raised embedding of sensors and possibly sensor lines has an advantageous effect on the material consumption in the manufacture of the housing. In addition, the heat dissipation can be done without problems with strong heat load of Schaltpols.

At this connection piece 4 can be connected to the feeding power line.

Daran anschließend ist der Hohlquerschnitt der Umfangswand 3 zu einer zylindrischen Hohlkammer erweitert, die sich etwa bis zur Höhenmitte der Umfangswand 3 erstreckt. In diese Hohlkammer ist mittels einer geeigneten Vergussmasse eine Vakuumschaltröhre 5 unbeweglich angebracht, die koaxial zur Mittellängsachse 6 angeordnet ist. Die Vakuumschaltröhre 5 umfasst in üblicher Weise einen Fest- und einen Bewegkontakt, deren Kontaktflächen nicht eingezeichnet unter Vakuum in der Schaltkammer der Schaltröhre 5 angeordnet sind. Der unbewegliche Festkontakt ist dabei ständig, z. B. über eine feste Stange, leitend mit dem Eingangsanschlussstück 4 verbunden. Demgegenüber ist der Bewegkontakt mit einer Bewegkontaktstange 7 verbunden, welche durch ein Führungsrohr mittig aus der unteren Stirnseite der Vakuumschaltröhre 5 heraussteht. Die Durchführung der Bewegkontaktstange ist dabei z.B. mittels eines geeigneten Faltenbalges hermetisch abgedichtet.Subsequently, the hollow cross section of the peripheral wall 3 is expanded to a cylindrical hollow chamber which extends approximately to the middle of the height of the peripheral wall 3. In this hollow chamber, a vacuum interrupter 5 is immovably mounted by means of a suitable potting compound, which is arranged coaxially to the central longitudinal axis 6. The vacuum interrupter 5 comprises in a conventional manner a fixed and a moving contact whose contact surfaces are not shown under vacuum in the switching chamber of the interrupter 5 are arranged. The immovable fixed contact is constantly, z. B. via a fixed rod, conductively connected to the input terminal 4. In contrast, the moving contact with a Bewegkontaktstange 7 is connected, which protrudes centrally through a guide tube from the lower end face of the vacuum interrupter 5. The implementation of the Bewegkontaktstange is e.g. hermetically sealed by means of a suitable bellows.

Im darunter liegenden Abschnitt vergrößert sich der von der Umfangswand 3 umschlossene Hohlquerschnitt des Schaltpolgehäuses 2 etwa kegelstumpfförmig. Im Wesentlichen entlang der Mittellängsachse 6 des Schaltpolgehäuses 2 ragt in den kegelförmigen Hohlquerschnitt eine Schaltstange 8 hinein, deren unteres Ende im Einbauzustand an einem nicht gezeigten Hubmechanismus angelenkt ist. In einem mittleren Längenbereich besteht die Schaltstange 8 aus einem Isolatorwerkstoff, während sie im oberen Endbereich aus leitfähigem Material besteht. Dabei ist das obere Ende der Schaltstange 8 unter axialer Abstützung mit dem Ende der Bewegkontaktstange 7 gekoppelt, so dass die Bewegkontaktstange 7 gemeinsam mit dem oberen Ende der Schaltstange 8 bewegt wird. Die Koppelung muss hierbei oberhalb eines Druckstückes 9 erfolgen, das einen teleskopartig längenveränderbaren Abschnitt der Schaltstange mittels einer Schraubendruckfeder überbrückt, die axial zwischen zwei Ringtellern der Schaltstange abgestützt ist. Hierdurch kann die Schaltstange 8 mit einem Überhub versehen werden, durch den die Kontakte im Einschaltzustand mit einer definierten Kraft aufeinandergedrückt werden, die aus der Federkraft der zusammengedrückten Schraubendruckfeder resultiert. Hierdurch ergeben sich Vorteile im Hinblick auf die Kurzschlussfestigkeit der Vakuumschaltröhre 5.In the section below, the area enclosed by the peripheral wall 3 hollow cross section of the Schaltpolgehäuses 2 increases approximately frustoconical. In essence, along the central longitudinal axis 6 of the Schaltpolgehäuses 2 projects into the conical hollow cross section a shift rod 8, whose lower end is hinged in the installed state to a lifting mechanism, not shown. In a middle length range, the shift rod 8 is made of an insulator material, while it is made of conductive material in the upper end region. In this case, the upper end of the shift rod 8 is coupled under axial support to the end of the Bewegkontaktstange 7, so that the Bewegkontaktstange 7 together with the upper end the shift rod 8 is moved. The coupling must in this case take place above a pressure piece 9, which bridges a telescopically length-variable portion of the shift rod by means of a helical compression spring, which is supported axially between two Ringtellern the shift rod. In this way, the shift rod 8 can be provided with an overstroke, by which the contacts are pressed in the on state with a defined force, which results from the spring force of the compressed helical compression spring. This results in advantages with regard to the short-circuit resistance of the vacuum interrupter 5.

Um bei eingeschalteter Vakuumschaltröhre 5 einen Stromfluss zu ermöglichen, ist der leitende Endbereich der Schaltstange 8 z. B. über ein flexibles Leiterband, einen Schleifkontakt oder ähnliches ständig leitend mit einem Abgangsanschlussstück 10 verbunden, das die Umfangswand 3 im Mittelbereich durchsetzt und seitlich von dieser absteht. Zur Isolierung des Abgangsanschlussstücks 10 ist ein Abzweigrohr 11 vorgesehen, das vorteilhaft einteilig mit der Umfangswand 3 ausgebildet sein kann. In das Abzweigrohr 11 ist in einem seitlichen Abstand zur Umfangswand 3 ein ringförmiger Stromsensor 12 eingebettet, mit dem sich der Stromfluss im Abgangsanschlussteil 10 auf übliche Weise induktiv erfassen lässt. Die zugeordnete Sensorleitung 13 des Stromsensors 12 ist dabei in einen Gehäusesteg 14 eingegossen, der senkrecht zwischen der Mitte des Abzweigrohrs 11 und dem Fuß des Schaltpolgehäuses 2 verläuft. Hierdurch wird auch eine winkelsteifere Anbindung des radial abragenden Abzweigrohrs 11 erreicht. Zur Erhöhung der Knicksteifigkeit des tunnelartigen Gehäusestegs 14 selbst, können eine oder mehrere in Umfangsrichtung der Umfangswand 3 verlaufende Verstärkungsrippen 15 vorgesehen werden.In order to enable current flow when the vacuum interrupter 5 is switched on, the conductive end region of the shift rod 8 is z. B. via a flexible conductor strip, a sliding contact or the like constantly conductively connected to a outgoing connector 10 which passes through the peripheral wall 3 in the central region and projects laterally from this. To isolate the outgoing fitting 10, a branch pipe 11 is provided, which may advantageously be formed integrally with the peripheral wall 3. In the branch pipe 11, a ring-shaped current sensor 12 is embedded in a lateral distance from the peripheral wall 3, with which the current flow in the outgoing terminal part 10 can be detected inductively in the usual way. The associated sensor line 13 of the current sensor 12 is cast in a housing web 14 which extends perpendicularly between the center of the branch pipe 11 and the foot of the Schaltpolgehäuses 2. As a result, a more rigid connection of the radially projecting branch pipe 11 is achieved. To increase the buckling resistance of the tunnel-like housing web 14 itself, one or more reinforcing ribs 15 extending in the circumferential direction of the circumferential wall 3 can be provided.

Um zusätzlich eine messtechnische Erfassung der am Abgangsanschlussteil 10 anliegenden Spannung zu ermöglichen, ist ein stabförmiger Spannungssensor 16 vorgesehen, der in der Draufsicht gesehen um einen Winkel von 90 Grad versetzt zum Stromsensor 12 an der Umfangswand 3 angeordnet ist. Die versetzte Anordnung des Spannungssensors 16 sowie die Verlegung der zugeordneten Sensorleitung sind in Fig. 1 wegen des Schnittverlaufes nur andeutungsweise eingezeichnet.In order additionally to permit metrological detection of the voltage applied to the output terminal part 10, a rod-shaped voltage sensor 16 is provided, which, viewed in plan view, is arranged at an angle of 90 degrees to the current sensor 12 on the circumferential wall 3. The staggered arrangement of the voltage sensor 16 and the laying of the associated sensor line are in Fig. 1 because of the cutting process only hinted drawn.

In Verbindung mit Figur 2 ist die Anordnung des Spannungssensors 16 an der Umfangswand 3 deutlicher zu erkennen, da das Schaltpolgehäuse 2 in Fig. 2 gegenüber dem Schnittverlauf gemäß Fig. 1 bezogen auf die Mittellängsachse 6 um 90 Grad gedreht geschnitten ist. Hier ist sichtbar, dass der stabförmige Spannungssensor 16 vollständig in einen von der Umfangswand 3 erhaben abstehenden Gehäusesteg 18 eingebettet bzw. eingegossen ist, der entsprechend dicker ist als der Durchmesser des Spannungssensors 16. Dabei verläuft der Spannungssensor 16 parallel zur Mittellängsachse 6 des Schaltpolgehäuses 2. Der Gehäusesteg 18 ist oberhalb des Spannungssensors 16 etwa bis zur Höhenmitte des Schaltpolgehäuses 2 verlängert, so dass ein erster Längenabschnitt der Sensorleitung 17 in die Stegverlängerung eingebettet ist. Am oberen Ende dieses Abschnittes ist die Sensorleitung 17 zunächst um etwa 90 Grad abgebogen und verläuft danach unter Anpassung an die Umfangskrümmung der Umfangswand 3 in einem erhabenen Ringwulst 19, der sich vom oberen Ende des Steges 18 in einer Querebene bis zum Abzweigrohr 11 erstreckt, in das er hineingeführt und an das Abgangsanschlussstück 10 angeschlossen ist. Dieser abgewinkelte und abgebogene Verlauf der Sensorleitung 17 entspricht somit dem Verlauf der erhabenen Außenkontur des Steges 18 sowie des daran anschließenden Ringwulstes 19 und ist in Verbindung mit der perspektivischen Ansicht gemäß Figur 3 sowie der Schnittdarstellung gemäß der Figur 5 gut zu erkennen. Wie dargestellt, ist es hierbei vorteilhaft, wenn der einen Sensorleitungsabschnitt aufnehmende Längenbereich des Gehäusesteges 14 sowie der sich daran anschließende Ringwulst 19 unter Anpassung an den Leitungsquerschnitt der Sensorleitung 17 verjüngt sind.Combined with FIG. 2 the arrangement of the voltage sensor 16 on the peripheral wall 3 can be seen more clearly, since the switching pole housing 2 in Fig. 2 according to the cutting process according to Fig. 1 is cut rotated 90 degrees relative to the central longitudinal axis 6. Here it is visible that the rod-shaped voltage sensor 16 is completely embedded or cast in a raised from the peripheral wall 3 housing web 18, which is correspondingly thicker than the diameter of the voltage sensor 16. In this case, the voltage sensor 16 is parallel to the central longitudinal axis 6 of the Schaltpolgehäuses second The housing bar 18 is extended above the voltage sensor 16 approximately to the middle of the height of the Schaltpolgehäuses 2, so that a first length portion of the sensor line 17 is embedded in the web extension. At the upper end of this section, the sensor line 17 is first bent by about 90 degrees and then passes to adapt to the circumferential curvature of the peripheral wall 3 in a raised annular bead 19 which extends from the upper end of the web 18 in a transverse plane to the branch pipe 11, in he led in and connected to the outlet fitting 10. This angled and bent course of the sensor line 17 thus corresponds to the course of the raised outer contour of the web 18 and the subsequent annular bead 19 and is in conjunction with the perspective view according to FIG. 3 and the sectional view according to the FIG. 5 clearly visible. As shown, it is advantageous in this case if the length of the housing web 14 receiving a sensor line section and the annular bulge 19 adjoining it are tapered while being adapted to the line cross section of the sensor line 17.

Dem Spannungssensor 16 diametrisch gegenüberliegend, also in Umfangsrichtung um 180 Grad versetzt, ist auf der Umfangswand 3 des Schaltpolgehäuses 2 auf gleicher Höhe ein zweiter, baugleicher Spannungssensor 16' angeordnet, der sich ebenfalls parallel zur Mittellängsachse 6 erstreckt und in einen zugeordneten Gehäusesteg 18' eingebettet ist. Dieser Spannungssensor 18' soll die Spannung des Eingangsanschlussstücks 4 erfassen, weshalb seine Sensorleitung 17' innerhalb des Schaltpolgehäuses 2 entlang der Umfangswand 3 nach oben geführt ist. Wie insbesondere in Verbindung mit Figur 4 zu sehen ist, verläuft die erst im oberen Bereich etwa rechtwinklig abgebogene Sensorleitung 17' schräg zur Mittellängsachse 6 in einem entsprechend verlängerten Gehäusesteg 18, dessen Querschnitt über die Höhenerstreckung der Sensorleitung 17' entsprechend verjüngt ist.The voltage sensor 16 diametrically opposite, so offset in the circumferential direction by 180 degrees, a second, identical voltage sensor 16 'is disposed on the peripheral wall 3 of the Schaltpolgehäuses 2 at the same height, which also extends parallel to the central longitudinal axis 6 and embedded in an associated housing web 18' is. This voltage sensor 18 'is intended to detect the voltage of the input terminal 4, which is why its sensor line 17' is guided upward within the switching pole housing 2 along the peripheral wall 3. As in particular in connection with FIG. 4 can be seen, the sensor line 17 ', which is only approximately bent at right angles in the upper region, extends obliquely to the central longitudinal axis 6 in a correspondingly extended housing web 18 whose cross section is correspondingly tapered over the height extent of the sensor line 17'.
