Abstract

A high voltage disconnect switch, including a countercontact piece having switch countercontacts and being arranged for connection to a source of high voltage. Resilient pre-contact pieces are insulatingly connected to the countercontact piece and include switch contacts disposed for contacting the switch countercontacts. Movable primary contact pieces are arranged to be movable from a first position of separation from the pre-contact pieces and the countercontact piece to a second position in which the primary contact pieces are in contact with the pre-contact pieces but not with the countercontact piece and to a third position in which the primary contact pieces are in contact with both the pre-contact pieces and the countercontact piece. The pieces are configured and arranged relative to one another so that during the closing of the switch the countercontacts contact the contacts after the primary contact pieces are moved to the second position and before they are moved to the third position, and during the opening of the switch the countercontacts separate from the contacts after the primary contact pieces are moved to the second position and before they are moved to the first position.

Description

Die Erfindung bezieht sich auf einen Hochspannungstrennschalter gemäss den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a high-voltage disconnector according to the features of the preamble of claim 1.

Das Kontaktsystem eines Trennschalters ist im allgemeinen so ausgelegt, dass es nur im Leerlauf, d.h. ohne Strombelastung ein- und auszuschalten ist. Aus diesem Grunde sind bei Trennschaltern keine Vorkehrungen getroffen, welche das Einschaltvermögen erhöhen oder welche eine Ausschaltung von Last- oder Kurzschlussströmen ermöglichen.The contact system of a circuit breaker is generally designed in such a way that it can only be can be switched on and off without current load. For this reason, no precautions have been taken with disconnectors which increase the switch-on capacity or which enable the switching off of load or short-circuit currents.

In bestimmten Fällen muss auch für Trennschalter ein gewisses Ein- und Ausschaltvermögen gefordert werden. Dies ist z. B. der Fall, wenn der Schalter zum Ein- und Ausschalten einer längeren Leitung verwendet wird.In certain cases, a certain switch-on and switch-off capacity must also be required for disconnectors. This is e.g. B. the case when the switch is used to switch a longer line on and off.

Wenn ein solcher Schalter weiterhin zum Ein-und Ausschalten eines Sammelschienenabschnittes benutzt wird, dem ein zweiter stromführender Sammelschienenabschnitt parallel geschaltet ist, kann ein Schaltlichtbogen während der Öffnungsbewegung der Trennerkontakte entstehen.If such a switch is also used to switch a busbar section on and off, to which a second current-carrying busbar section is connected in parallel, a switching arc can occur during the opening movement of the isolating contacts.

Bei bekannten Trennschaltern, die keine besonderen Einrichtungen zur Erhöhung des Schaltvermögens haben, können durch die entstehenden Schaltfunken die Kontaktflächen beschädigt werden. Hierdurch wird mit der Zeit die Dauerstromtragfähigkeit vermindert. Je nach Strombelastung, der Aggressivität der Atmosphäre und der Dauer der Einwirkungen können derart beschädigte Kontaktstellen einen so hohen Übergangswiderstand annehmen, dass schliesslich die Kontaktstücke verschmoren und Betriebsstörungen die Folge sind.In the case of known disconnectors, which have no special devices for increasing the switching capacity, the contact surfaces can be damaged by the switching sparks which arise. This reduces the continuous current carrying capacity over time. Depending on the current load, the aggressiveness of the atmosphere and the duration of the effects, such damaged contact points can assume such a high contact resistance that the contact pieces will eventually burn up and malfunctions will result.

Aus der DE-A-3 120 129 ist ein Hochspannungstrennschalter mit einer Schere bekannt. Dieser Hochspannungstrennschalter ist mit Hauptkontaktstücken und einem Gegenkontaktstück ausgerüstet, wobei, um die oben genannten Mängel zu beseitigen, federnde, isoliert angebrachte Vorkontaktstücke vorgesehen sind, die mit zusätzlichen Schaltkontakten beim Einschalten vor den Hauptkontaktstücken schliessen und beim Ausschalten nach den Hauptkontaktstücken öffnen.From DE-A-3 120 129 a high voltage disconnector with scissors is known. This high-voltage isolating switch is equipped with main contact pieces and a counter contact piece, whereby, in order to eliminate the above-mentioned defects, resilient, insulated pre-contact pieces are provided, which close with additional switch contacts when switched on before the main contact pieces and open after switching off after the main contact pieces.

Diese zusätzlichen Schaltkontakte verfügen jedoch über einen relativ geringen Hub sowie über eine geringe Schaltgeschwindigkeit. Dadurch kann sich zwischen diesen zusätzlichen Schaltkontakten ein Lichtbogen ausbilden, der zu Abbrand und Kontaktverschlechterung führt. Desweiteren kann ein solcher Lichtbogen zwischen den zusätzlichen Schaltkontakten dazu führen, dass die Vorkontaktstücke ihre Funktion nicht mehr erfüllen und zwischen den Hauptkontaktstücken und dem Gegenkontaktstück ein Schaltlichtbogen auftritt, was die oben genannten Nachteile zur Folge hat.However, these additional switching contacts have a relatively short stroke and a low switching speed. As a result, an arc can form between these additional switching contacts, which leads to erosion and deterioration of the contact. Furthermore, such an arc between the additional switching contacts can lead to the precontact pieces no longer fulfilling their function and a switching arc occurring between the main contact pieces and the mating contact piece, which has the disadvantages mentioned above.

Der Erfindung liegt die Aufgabe zugrunde, eine Kontaktanordnung für Hochspannungstrennschalter verfügbar zu machen, bei der die Schaltgeschwindigkeit sowie der Hub an der Kontaktstelle zwischen den zusätzlichen Schaltkontakten vergrössert wird.The invention has for its object to provide a contact arrangement for high-voltage disconnectors, in which the switching speed and the stroke at the contact point between the additional switching contacts is increased.

Diese Aufgabe wird erfindungsgemäss durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in the characterizing part of claim 1.

Der Vorteil der Erfindung besteht darin, dass der beim Ausschalten zwischen den zusätzlichen Schaltkontakten auftretende Lichtbogen rasch erlöscht und die Entstehung eines Lichtbogens zwischen den Hauptkontaktstücken und dem Gegenkontaktstück mit Sicherheit verhindert wird.The advantage of the invention is that the arc occurring between the additional switching contacts is quickly extinguished and the occurrence of an arc between the main contact pieces and the counter contact piece is prevented with certainty.

Weiterbildungen der Erfindung sowie zweckmässige Ausgestaltungen sind den Unteransprüchen zu entnehmen, insbesondere wird durch die Löscheinrichtung gemäss Anspruch 2 die Effektivität der erfindungsgemässen Massnahme wesentlich erhöht.Further developments of the invention and expedient configurations can be found in the subclaims, in particular the effectiveness of the measure according to the invention is significantly increased by the extinguishing device according to claim 2.

In der Zeichnung sind zwei Ausführungsbeispiele von Kontaktanordnungen von Hochspannungstrennschaltern dargestellt. Es zeigen

  • Fig. 1 die Kontaktanordnung eines Hochspannungstrennschalters, die die Merkmale des Standes der Technik aufweist,
  • Fig. 2 eine Seitenansicht dieser Kontaktanordnung,
  • Fig. 3 ein Ausführungsbeispiel der erfindungsgemässen Kontaktanordnung und
  • Fig. 4 deren Seitenansicht.
The drawing shows two exemplary embodiments of contact arrangements of high-voltage disconnectors. Show it
  • 1 shows the contact arrangement of a high-voltage disconnector, which has the features of the prior art,
  • 2 is a side view of this contact arrangement,
  • Fig. 3 shows an embodiment of the contact arrangement according to the invention and
  • Fig. 4 the side view.

In Fig. 1 sind mit 1 die Vorkontaktstücke bezeichnet, die mit den Hauptkontaktstücken 2 zusammenwirken. Die Vorkontaktstücke sind in einer isolierenden Halterung 3 am Gegenkontaktstück 4 befestigt. An den Vorkontaktstücken 1 sind Schaltkontakte 5 und am Gegenkontaktstück 4 die mit ihnen zusammenwirkenden Gegenkontakte 5' angeordnet.In Fig. 1, 1 denotes the pre-contact pieces which cooperate with the main contact pieces 2. The pre-contact pieces are fastened to the mating contact piece 4 in an insulating holder 3. Switch contacts 5 are arranged on the pre-contact pieces 1 and the counter contacts 5 ′ which cooperate with them are arranged on the counter contact piece 4.

Während des Einschaltvorganges kommen zunächst die Vorkontaktstücke 1 in bekannter Weise mit den beweglichen Hauptkontaktstücken 2 an den Scherenholmen in Berührung. Da die Vorkontaktstücke jedoch in der isolierenden Halterung 3 am Gegenkontaktstück 4 befestigt sind, wird der Stromkreis erst im Zuge der weiteren Einschaltbewegung geschlossen, nämlich dann, wenn die Vorkontaktstücke 1 elektrisch leitend das Gegenkontaktstück 4 berühren. Diese Berührung erfolgt zunächst an den Schaltkontakten 5, 5' bevor die beweglichen Hauptenkontakte 2 den Gegenkontakt 4 berühren. Die Schaltkontakte 5, 5' übernehmen auch beim Ausschaltvorgang des Trennschalters die Funktion des Abschaltens von Rest-oder Kommutierungsströmen. Gegen den hierbei von dem Abschaltlichtbogen ausgehenden Abbrand können die Schaltkontakte besonders geschützt werden, indem man sie mit abbrandfestem Material ausstattet.During the switch-on process, the pre-contact pieces 1 first come into contact with the movable main contact pieces 2 on the scissor bars in a known manner. However, since the pre-contact pieces are fastened in the insulating holder 3 to the mating contact piece 4, the circuit is only closed in the course of the further switch-on movement, namely when the pre-contact pieces 1 touch the mating contact piece 4 in an electrically conductive manner. This contact takes place first at the switching contacts 5, 5 'before the movable main contacts 2 touch the counter contact 4. The switching contacts 5, 5 'also take over the function of switching off residual or commutation currents when the disconnector is switched off. The switching contacts can be particularly protected against the erosion caused by the shutdown arc by equipping them with erosion-resistant material.

Aus Fig. 2 geht die Lage der Schaltkontakte 5 und die Form der Vorkontaktstücke 1 hervor. Die Vorkontaktstücke 1 sind C-förmig ausgebildet und sind in den isolierenden Halterungen 3 gelagert. Diese Lagerung und die Schaltkontakte 5, 5' sind an den Enden des Gegenkontaktstückes 4 angeordnet, wobei als Schutz gegen eine mögliche Beeinflussung der Oberfläche des Gegenkontaktes durch den Schaltlichtbogen eine Blende 6, beispielsweise aus Kunststoff angordnet ist. Ausserdem verhindert die Blende 6 das seitliche Anschlagen des Scherenholmes, z. B. unter der Einwirkung starker Kurzschlusskräfte an der Schaltkontaktanordnung der Vorkontaktstücke.2 shows the position of the switching contacts 5 and the shape of the pre-contact pieces 1. The pre-contact pieces 1 are C-shaped and are mounted in the insulating holders 3. This mounting and the switching contacts 5, 5 'are arranged at the ends of the mating contact piece 4, with an aperture 6, for example made of plastic, being arranged as protection against possible influencing of the surface of the mating contact by the switching arc. In addition, the panel 6 prevents the side on hitting the scissor spar, z. B. under the influence of strong short-circuit forces on the switch contact arrangement of the pre-contact pieces.

Die erfindungsgemässe Ausgestaltung der Kontaktanordnung nach den Fig. 3 und 4 hat den Vorteil, dass der Hub der Kontaktstücke 8', 8" der zusätzlichen Schaltkontakte 8 wesentlich vergrössert wird, indem der Hub der Vorkontaktstücke 1 nicht mehr über ein einarmiges sondern über ein zweiarmiges Hebelsystem 7, 7' auf die an den den Hauptkontaktstücken 2 abgewandten Enden der gekreuzten Hebel 7, 7' angeordneten Schaltkontakte 8 übertragen wird. Dadurch wird eine Vergrösserung der Schaltgeschwindigkeit bzw. des Hubes an der Kontaktstelle erreicht. Der gemeinsame Befestigungspunkt 10 der zangenartig um diesen schwenkbaren Hebel 7, 7' ist gegenüber dem Gegenkontaktstück 4, ebenso wie die Hebel selbst, isoliert. Mittels einer Feder 11, im Ausführungsbeispiel als Druckfeder ausgebildet, wird ein Spreizen der Vorkontaktstücke 1 im ausgeschalteten Zustand sichergestellt. Ein Anschlag 12 begrenzt diesen Spreizhub.3 and 4 has the advantage that the stroke of the contact pieces 8 ', 8 "of the additional switching contacts 8 is significantly increased by the stroke of the pre-contact pieces 1 no longer using a single-armed but a two-armed lever system 7, 7 'is transferred to the switching contacts 8 arranged at the ends of the crossed levers 7, 7' facing away from the main contact pieces 2. This increases the switching speed and / or the stroke at the contact point Lever 7, 7 'is insulated from the mating contact piece 4, just like the levers themselves, by means of a spring 11, designed as a compression spring in the exemplary embodiment, to ensure that the pre-contact pieces 1 are spread out in the switched-off state.

Die Löschung der beim Ausschalten entstehenden Lichtbögen muss möglichst rasch erfolgen, um einen unnötigen Abbrand zu vermeiden. Hierzu dient eine Löscheinrichtung 9, die aus sogenanntem Hartgas-Material besteht. Dieses Material wird in unmittelbarer Umgebung der zusätzlichen Schaltkontakte 8 angeordnet, so dass beim Entstehen des Lichtbogens eine intensive Gasströmung erzeugt wird, die eine Löschung des Lichtbogens herbeiführt. Das Hartgas-Material kann in Form einer Hülse ausgebildet sein, die in ihrem Inneren die Schaltkontakte 8 aufnimmt, wobei das bewegliche Kontaktstück 8" sich annähernd in der Achse der Hülse bewegt, während das feststehende Kontaktstück 8' als federndes Kontaktstück, z.B. radial in die Hülse 9 eingreift. Die feststehenden Kontaktstücke 8' sind mit dem Gegenkontaktstück 4 über einen Kontaktträger 13 verbunden.The arcing that occurs when switching off must be extinguished as quickly as possible to avoid unnecessary burning. For this purpose, an extinguishing device 9 is used, which consists of so-called hard gas material. This material is arranged in the immediate vicinity of the additional switching contacts 8, so that an intense gas flow is generated when the arc arises, which causes the arc to be extinguished. The hard gas material can be designed in the form of a sleeve, which receives the switching contacts 8 in its interior, the movable contact piece 8 "moving approximately in the axis of the sleeve, while the fixed contact piece 8 'as a resilient contact piece, for example radially into the Sleeve 9. The fixed contact pieces 8 'are connected to the counter contact piece 4 via a contact carrier 13.

Den Schutz der zusätzlichen Kontaktstücke 8 der Löscheinrichtung 9 sowie des oberen Teiles des Hebelsystems gegen Witterungseinflüsse übernimmt eine Haube 14, die aus Metall oder aus witterungsbeständigem Kunststoff bestehen kann.The protection of the additional contact pieces 8 of the extinguishing device 9 and of the upper part of the lever system against weather influences is carried out by a hood 14, which can be made of metal or weather-resistant plastic.
