Abstract

A multipole high voltage circuit breaker is provided with a housing formed of a pair of flanged housing shells which are snap-fitted together along adjoining peripheral flanges. The thus assembled housing is provided with a plurality of intermediate walls and end walls for defining a plurality of compartments corresponding to respective ones of the poles of the circuit breaker. A switch actuator shaft is formed of a plurality of tubular bodies which are housed in respective ones of the compartments and coupled together for joint rotation. A plurality of fixed contacts extend through the housing and are bent so as to be directed radially toward the switch actuator shaft. The arrangement further includes a plurality of switch elements arranged on the switch actuator shaft, the elements being movable between engaged and disengaged positions with respect to the fixed internal contacts upon rotation of the switch actuator shaft. In a preferred arrangement, the shells which form the housing are identical to one another so as to be producible in only one mould. Each shell is provided with a peripheral flange which contains pins and mating recesses. When assembled, the pins engage in the recesses and are deformed to prevent separation of the shells. In this manner, an easily assembly multipole circuit breaker is produced.

Die Erfindung bezieht sich auf einen mehrpoligen Hochspannungs-Lastschalter nach dem Oberbegriff des Anspruches 1.The invention relates to a multi-pole high-voltage circuit breaker according to the preamble of claim 1.

Es ist bereits ein Hochspannungs-Lastschalter der im Oberbegriff des Anspruches 1 genannten Art bekannt (DE-U 79 21 721).There is already a high-voltage circuit breaker of the type mentioned in the preamble of claim 1 (DE-U 79 21 721).

Aufgabe der Erfindung ist es, den Hochspannungs-Lastschalter der im Oberbegriff des Anspruches 1 genannten Art so auszubilden, daß seine Teile auf besonders einfache Weise miteinander vereinigbar sind.The object of the invention is to design the high-voltage circuit breaker of the type mentioned in the preamble of claim 1 in such a way that its parts can be combined with one another in a particularly simple manner.

Die gestellte Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruches 1 angegebene Ausbildung gelöst.The object is achieved by the training specified in the characterizing part of claim 1.

  • FIG. 6 shows an enlarged end view of a current bridge compared to FIG. 1.

In Fig. 1 ist mit 1a eine als Schale ausgebildete erste Hälfte eines Gehäuses aus Isolierstoff bezeichnet.In Fig. 1, a first half of a housing made of insulating material is designated as a shell.

Die zweite Hälfte des Gehäuses besteht aus einer der ersten Gehäusehälfte gleichen und deshalb ebenfalls mit 1a bezeichneten Schale. Da die Schalen 1a untereinander gleich sind, genügt zu ihrer Herstellung eine einzige Form.The second half of the housing consists of a shell which is the same as the first half of the housing and is therefore also designated by 1a. Since the shells 1a are identical to one another, a single shape is sufficient for their production.

Beide Schalen 1a haben einen etwa halbkreisförmigen Querschnitt (Fig.4) und besitzen einen umlaufenden Flansch 1b.Both shells 1a have an approximately semicircular cross section (FIG. 4) and have a circumferential flange 1b.

In der Bestimmungslage liegen die Flansche 1b der Schalen 1a aufeinander und umschließen einen etwa zylindrischen Raum.In the position of determination, the flanges 1b of the shells 1a lie on one another and enclose an approximately cylindrical space.

Zum gegenseitigen Festlegen besitzen die Flansche 1b Ausnehmungen 1c (Fig.4) und Zapfen 1d. Die Ausnehmungen 1c und Zapfen 1d sind so angeordnet, daß nach der Vereinigung der Schalen 1a die Zapfen 1d der einen Schale 1a in die Ausnehmungen 1c der anderen Schale 1a eingreifen und umgekehrt.For mutual fixing, the flanges 1b have recesses 1c (FIG. 4) and pins 1d. The recesses 1c and pin 1d are arranged such that after the shells 1a have been combined, the pins 1d of one shell 1a engage in the recesses 1c of the other shell 1a and vice versa.

In nicht dargestellter Weise sind die Zapfen 1d in ihrer Bestimmungslage am freien Ende jeweils zu einem Nietkopf verformt, der so angeordnet ist, daß die beiden vereinigten Schalen 1a nicht mehr ohne Zerstörung aller Nietköpfe voneinander abgehoben werden können.In a manner not shown, the pins 1d are each deformed in their position of determination at the free end to form a rivet head which is arranged such that the two combined shells 1a can no longer be lifted from one another without destroying all of the rivet heads.

Jede der Schalen weist pro Pol zwei radial angeformte Schlote 1e auf, in die jeweils ein Kontaktstück 2 eingreift.Each of the shells has two radially molded chimneys 1e per pole, in each of which a contact piece 2 engages.

Jedes der Kontaktstücke 2 ist einmal abgekröpft (Fig.4) und von innen nach außen bis zur Anlage der inneren Biegekante an die Innenseite der zugeordneten Schale 1a in den jeweiligen Schlot 1e eingesteckt und gegen Zurückziehen festgelegt. Im dargestellten Beispiel weisen die in den Hohlraum der Schalen ragenden Abkröpfungen der Kontaktstücke 2 auf die Schalenachse (Fig.4).Each of the contact pieces 2 is cranked once (Fig.4) and from the inside to the outside until the inner bending edge abuts the inside of the assigned shell 1a inserted into the respective chimney 1e and fixed against withdrawal. In the example shown, the bent portions of the contact pieces 2 projecting into the cavity of the shells point to the shell axis (FIG. 4).

Ein Verschieben der Kontaktstücke 2 in Einsteckrichtung ist durch die Anlage ihrer inneren Biegekante gegen die Innenseite der zugeordneten Schale 1a verhindert.Movement of the contact pieces 2 in the insertion direction is prevented by the abutment of their inner bending edge against the inside of the assigned shell 1a.

Gegen Zurückziehen ist jedes Kontaktstück 2 durch ein Federstück 3 gesichert, das sich zwischen den aneinander angrenzenden Flächen des jeweiligen Schlotes 1e und des Kontaktstückes 2 erstreckt, sowie in eine nicht gezeigte Vertiefung des Kontaktstückes 2 eingreift und auf den Kopf des Schlotes 1e umgelegt ist.Each contact piece 2 is secured against retraction by a spring piece 3, which extends between the adjacent surfaces of the respective chimney 1e and the contact piece 2, and which engages in a recess (not shown) of the contact piece 2 and is folded over onto the head of the chimney 1e.

Anstelle zweier Kontaktstücke 2 pro Pol kann jede Schale 1a pro Pol auch nur mit einem Kontaktstück 2, ausgerüstet sein. In letzteren Falle könnte in nicht gezeigter Weise der dem einen Kontaktstück zugeordnete Schlot 1e auf dem Scheitel der jeweiligen Schale 1a angeformt sein.Instead of two contact pieces 2 per pole, each shell 1a per pole can also be equipped with only one contact piece 2. In the latter case, the chimney 1e assigned to the one contact piece could be formed on the apex of the respective shell 1a in a manner not shown.

Im dargestellten Beispiel ist jeweils das eine Kontaktstück 2 der einen Schale 1a dem diagonal gegenüberliegenden Kontaktstück 2 der anderen Schale 1a zugeordnet. Die jeweils einander zugeordneten Kontaktstücke 2 pro Pol sind durch-eine Strombrücke verbindbar. Die Strombrücken aller Pole sind von einer Welle getragen, die aus einer Stellung 0 in eine Schaltstellung ERDE und in entgegengesetzter Richtung in eine Schaltstellung EIN drehbar ist. In der Schaltstellung ERDE sind die einen einander zugeordneten Kontaktstücke 2 eines Poles miteinander durch die jeweilige Strombrücke miteinander verbunden, während in der Schaltstellung EIN die anderen einander zugeordneten Kontaktstücke 2 eines Poles durch die jeweilige Strombrücke miteinander verbunden sind. Im Beispiel handelt es sich also um einen sogenannten Dreistellungsschalter.In the example shown, one contact piece 2 of the one shell 1a is assigned to the diagonally opposite contact piece 2 of the other shell 1a. The respectively associated contact pieces 2 per pole can be connected by a current bridge. The current bridges of all poles are carried by a shaft which can be rotated from a position 0 to a switch position EARTH and in the opposite direction to a switch position ON. In the switch position EARTH are an associated contact pieces 2 of a pole connected to each other by the respective current bridge, while in the switch position ON the other associated contact pieces 2 of a pole are connected to each other by the respective current bridge. In the example, it is a so-called three-position switch.

Bei gegebener Stellung 0 der Welle und nur zwei Kontaktstücken 2 pro Pol würde es sich um einen Zweistellungsschalter handeln.Given the position 0 of the shaft and only two contact pieces 2 per pole, it would be a two-position switch.

Jede Strombrücke besteht nach den Fig. 1, 5 und 6 aus zwei Kontaktbacken 4, die von zwei untereinander gleichen Bügeln 5 (Fig.1 und 6) umgriffen sind, die mit ihren Schenkeln die Rücken der Kontaktbacken 4 umgreifen.According to FIGS. 1, 5 and 6, each current bridge consists of two contact jaws 4, which are surrounded by two mutually identical brackets 5 (FIGS. 1 and 6), which grip the backs of the contact jaws 4 with their legs.

An ihren beiden Enden ragen die Kontaktbacken 4 aus den U- förmigen Bügeln 5 heraus und besitzen dort, wie aus Fig. 5 ersichtlich, einen zum kontaktierenden Eingriff der Kontaktbacken 4 ausreichenden Abstand.At their two ends, the contact jaws 4 protrude from the U-shaped brackets 5 and there, as can be seen in FIG. 5, have a sufficient distance for contacting engagement of the contact jaws 4.

Wie aus Fig. 6 ersichtlich, erstrecken sich zwischen den Kontaktbacken 4 und den Rücken der Kontaktbacken 4 Kontaktdruckfedern 6, die auch zum Zusammenhalten der Kontaktbacken 4 und der Bügel 5 dienen.As can be seen from FIG. 6, contact pressure springs 6 extend between the contact jaws 4 and the back of the contact jaws 4 and also serve to hold the contact jaws 4 and the bracket 5 together.

Die Welle ist aus Rohrkörpern 7 aus Isolierstoff und einem ebenfalls aus Isolierstoff bestehenden Mitnehmer 1o zusammengesetzt. Pro Pol ist jeweils ein Rohrkörper 7 vorgesehen.The shaft is composed of tubular bodies 7 made of insulating material and a driver 1o likewise made of insulating material. One tubular body 7 is provided for each pole.

An dem einen Ende jedes Rohrkörpers 7 ist eine umlaufende Lagernut 7a mit einem eingelegten Gleitring 8 angeordnet und vor der Lagernut 7a eine Außenverzahnung 7b (Fig.2).At one end of each tubular body 7 is one encircling bearing groove 7a with an inserted sliding ring 8 and an external toothing 7b in front of the bearing groove 7a (FIG. 2).

Am anderen Ende jedes Rohrkörpers 7 ist eine Innenverzahnung 7c angeformt (Fig.3).An internal toothing 7c is formed on the other end of each tubular body 7 (FIG. 3).

Jeder Rohrkörper 4 besitzt ferner zwei angeformte Flügel 7d.Each tubular body 4 also has two integrally formed wings 7d.

In der Ebene der Flügel 7d ragt ein an den Rohrkörper 7 angeformtes Querrohr 7e (Fig.2,3, und 5) hinein.A cross tube 7e (FIGS. 2, 3, and 5) formed on the tubular body 7 projects into the plane of the wings 7d.

Ab den Enden jedes Querrohres 7e ist der jeweilige Flügel 7d in zwei Hälften geteilt, wie aus Fig. 5 ersichtlich.From the ends of each cross tube 7e, the respective wing 7d is divided into two halves, as can be seen in FIG. 5.

In jedes Querrohr 7e ist jeweils eine der aus dem Teilen 4,5 und 6 bestehenden Strombrücken verdrehsicher eingeschoben und zwar soweit, daß die Kontaktbacken 4 zwischen die Hälften der Flügel 7d ragen (Fig.5).In each cross tube 7e one of the current bridges consisting of parts 4, 5 and 6 is inserted in such a way that it cannot rotate, to the extent that the contact jaws 4 project between the halves of the wings 7d (FIG. 5).

Gegen Verschieben aus ihrer Soll-Lage sind die Strombrücken durch Formelemente 9 gesichert, von denen je eines auf jeder Hälfte der Flügel 7d unverlierbar aufgesteckt ist.The current bridges are secured against displacement from their desired position by shaped elements 9, one of which is captively attached to each half of the wings 7d.

In der Bestimmungslage greift jeweils die Außenverzahnung 7b eines Rohrkörpers 7 in die Innenverzahnung 7c eines benachbarten Rohrkörpers 7 ein.In the determination position, the external toothing 7b of a tubular body 7 engages in the internal toothing 7c of an adjacent tubular body 7.

Auf die Außenverzahnung 7b des an einem Ende eingriffsfreien Rohrkörpers 7 ist eine Innenverzahnung des ebenfalls rohrförmigen Mitnehmers 10 aufgesteckt, der in seiner freien Stirnfläche zwei Ausnehmungen 10a für den Eingriff einer nicht dargestellten Antriebswelle aufweist (Fig.1).An internal toothing is on the external toothing 7b of the tubular body 7 which does not engage at one end tion of the likewise tubular driver 10, which has two recesses 10a in its free end face for the engagement of a drive shaft (not shown) (FIG. 1).

Ferner besitzt der Mitnehmer 10 eine Lagernut 10b, die einen Gleitring 8 aufweist.The driver 10 also has a bearing groove 10b which has a slide ring 8.

In Fig. 1 sind alle Rohrkörper 7 und der Mitnehmer 10 in einer Flucht dargestellt. Durch Zusammenstecken aller Teile ergibt sich die Welle des Lastschalters.In Fig. 1, all tubular body 7 and the driver 10 are shown in alignment. By plugging all the parts together, the shaft of the load switch results.

Jede Schale 1a besitzt zwei Stirnwände 1f und zwischen jedem Pol eine Zwischenwand 1g (Fig.4), die in ihrer Bestimmungslage gemeinsam mit einer Stirnwand 1f beziehungsweise einer Zwischenwand 1g der anderen Schale 1a eine Begrenzungswand für einen Pol bilden.Each shell 1a has two end walls 1f and between each pole an intermediate wall 1g (FIG. 4) which, in their position of determination, together with an end wall 1f or an intermediate wall 1g of the other shell 1a form a boundary wall for a pole.

Die Zwischenwände 1g trennen die Pole untereinander, während die Stirnwände 11 das Gehäuse nach außen abschließen.The intermediate walls 1g separate the poles from one another, while the end walls 11 close off the housing.

Die Stirnwände 1f und die Zwischenwände 1g besitzen jeweils die Form einer halben Ringscheibe (Fig.4).The end walls 1f and the intermediate walls 1g each have the shape of a half washer (FIG. 4).

Nach dem Zusammenfügen der Schalen 1a greifen die Stirn- und Zwischenwände 1f, g jeweils in eine der Gleitringe 8 der von den Schalen 1a umschlossenen und aus den Rohrkörpern 7 sowie dem Mitnehmer 1o gebildeten Welle ein, die im Beispiel somit viermal gelagert ist.After the shells 1a have been joined together, the end walls and intermediate walls 1f, g each engage in one of the sliding rings 8 of the shaft enclosed by the shells 1a and formed from the tubular bodies 7 and the driver 10, which is thus mounted four times in the example.
