Description

Die Erfindung betrifft Schaltanlagen mit von magnetischen Antriebseinrichtungen steuerbaren Schaltgeräten, insbesondere mit Vakuumschützen, wobei die Schaltgeräte entsprechend der Anzahl zu schaltender Phasen jeweils blockweise in einem Gehäuse angeordnet und von diesem jeweils dreiseitig umgeben sind und im Gehäuse von einem oberen und von einem unteren Kontaktanschlußstück lösbar von demselben schraubbefestigt sind.
Schaltanlagen der eingangs definierten Art sind u. a. aus der Druckschrift "Catalog HG 11.21, 1997, 3TL Vacuum Contactors, Page 3/5" bekannt.
Die Schaltanlagen sind mit Vakuumschützen im Spannungsbereich bis zu 12 kV (Kilo-Volt) ausgestattet, wobei jeweils drei Vakuumschütze gemeinsam in einem Gehäuse untergebracht sind.
Die drei Vakuumschütze sind von dem Gehäuse dreiseitig derart umgeben, daß die oberen und die unteren Kontaktanschlüsse der Vakuumschütze von vorne her frei zugänglich sind. Das Gehäuse der Vakuumschütze wird außerdem von unten durch eine magnetische Antriebseinrichtung und von oben durch eine isolierte Abdeckung begrenzt. Die konstruktiven Anforderungen hinsichlich der notwendigen Spannungfestigkeit und der thermischen Belastbarkeit sind durch entsprechend große Abstände der spannungsführenden Teile zueinander sowie durch entsprechend große Dimensionierung der Kontaktanschlußstücke mit großer Oberfläche zur ausreichenden Wärmeableitung gelöst.
Die der Erfindung zugrundeliegende Aufgabe besteht darin, Schaltanlagen bei Erweiterung des Spannungsbereiches auf 24 kV anzugeben, bei denen die Schaltgeräte ebefalls in kompakter Bauweise aufgebaut und die durch den höheren Spannungsbereich bedingten höheren Erwärmungen wesentlich verbessert abgeleitet sind.
Erfindungsgemäß wird dies durch die Merkmale

  • 1.1 die Schaltgeräte weisen jeweils separate Gehäuse auf, 1.2 die Gehäuse sind jeweils durch zwei separate, spiegelbildlich zueinander angeordnete Polschalen gebildet,
  • 1.3 das obere und das untere Kontaktanschlußstück bilden jeweils einen oberen und einen unteren Kühlkörper,
  • 1.4 der obere und der untere Kühlkörper sind jeweils zwischen separat zugeordneten Vakuumschütz-Befestigungsstegen der Polschalen lösbar befestigt,
  • 1.5 der obere Kühlkörper ist im Umfangsbereich der Schaltgeräte mit zentrisch zu diesen verlaufende Lüftungsschlitze versehen,
  • 1.6 der untere Kühlkörper ist im Umfangsbereich der Schaltgeräte mit mittensymmetrisch angeordneten Lufteintrittsöffnungen versehen,
    • erreicht.The invention relates to switchgear with switchgear that can be controlled by magnetic drive devices, in particular with vacuum contactors, the switchgear being arranged block-wise in a housing in accordance with the number of phases to be switched and surrounded by this on three sides in each case and detachably in the housing by an upper and a lower contact connecting piece the same are screw-fastened.
    Switchgear of the type defined in the introduction are known, inter alia, from the publication "Catalog HG 11.21, 1997, 3TL Vacuum Contactors, Page 3/5".
    The switchgear is equipped with vacuum contactors in the voltage range up to 12 kV (kilo-volts), whereby three vacuum contactors are housed together in one housing.
    The three vacuum contactors are surrounded on three sides by the housing in such a way that the upper and lower contact connections of the vacuum contactors are freely accessible from the front. The housing of the vacuum contactors is also delimited from below by a magnetic drive device and from above by an insulated cover. The design requirements with regard to the necessary dielectric strength and the thermal load-bearing capacity are solved by correspondingly large distances between the live parts and by correspondingly large dimensions of the contact connectors with a large surface area for sufficient heat dissipation.
    The object on which the invention is based is to specify switchgear assemblies when the voltage range is expanded to 24 kV, in which the switching devices are also constructed in a compact design and the higher heating caused by the higher voltage range is derived in a substantially improved manner.
    According to the invention, this is due to the features
  • 1.1 the switching devices each have separate housings, 1.2 the housings are each formed by two separate pole shells arranged in mirror image to one another,
  • 1.3 the upper and the lower contact connecting piece each form an upper and a lower heat sink,
  • 1.4 the upper and the lower heat sink are detachably fastened between separately assigned vacuum contactor fastening webs of the pole shells,
  • 1.5 the upper heat sink is provided in the peripheral area of the switchgear with ventilation slots running centrally to it,
  • 1.6 the lower heat sink is provided in the circumferential area of the switching devices with center-symmetrically arranged air inlet openings,
    • reached.

    Durch den Ersatz des einstückigen Gehäuseteils durch die den Schaltgeräten jeweils zugeordneten zwei Polschalen lassen sich ohne wesentliche Vergrößerung des Einbauvolumens auch für den Spannungsbereich bis 24 kV kompakte Schaltanlagen mit den notwendiger Weise einzuhaltenen Spannungsfestigkeiten herstellen. Die beiden spiegelbidlich zueinander angeordneten Polschalen, die unmittelbar auf der magnetischen Antriebseinrichtung schraubbefestigt sind, lassen sich darüber hinaus für die unterschiedlichen Schaltgeräte bzw. Vakuumschütze in einfacher Weise durch verschiedene Abstände zueinander anpassen. Mit den einheitlichen Polschalen lassen sich also ohne konstruktive Veränderungen praktisch beliebige Gehäuse zur Aufnahme der Schaltgeräte oder Vakuumschütze zusammenstellen. Die gleichzeitge Ausgestalltung der oberen und unteren Kontaktanschlußstücke als entsprechende obere und untere Kühlkörper ermöglichen eine ausreichende Wärmeableitung für den 24 kV - Spannungsbereich. Als besonders vorteilhaft ist in diesem Zusammenhang die Anordnung der Lüftungsschlitze im oberen Kühlkörper und die der Lufteintrittsöffnungen im unteren Kühlkörper anzusehen. Durch die nach oben unverschlossenen Polschalen wird von unten her durch die Lufteintrittsöffnungen ein Kühlluftstrom gezieir am Umfang des Schaltgerätes bzw. des Vakuumschützes und deren Kontaktanschlüsse vorbeigeführt, der durch die Lüftungsschlitze der oberen Kühlkörper entweicht. Durch diesen gezielt lenkbaren Kühlluftstrom ist praktisch ein aktives Kühlsystem wirksam, mit dem die erhöhte thermische Belastbarkeit in diesem Spannungsbereich erreicht ist.By replacing the one-piece housing part with the Leave switching devices assigned to two pole shells itself without significantly increasing the installation volume for the voltage range up to 24 kV compact switchgear with the necessary dielectric strengths to be observed produce. The two are arranged in mirror image to each other Pole shells that are directly on the magnetic drive device are screw-fastened, can also be for the different switching devices or vacuum contactors in adapt easily to each other by different distances. With the uniform pole shells, you can without constructive changes practically any housing Assemble the switchgear or vacuum contactors. The simultaneous configuration of the upper and lower contact fittings as corresponding upper and lower heat sinks allow adequate heat dissipation for the 24 kV voltage range. Is particularly advantageous in this connection the arrangement of the ventilation slots in the upper heat sink and that of the air inlet openings in the lower View heat sink. Through the unlocked top Pole shells are from below through the air inlet openings a cooling air flow geieir on the circumference of the switching device or the vacuum contactor and their contact connections, through the ventilation slots of the upper heat sink escapes. Through this specifically steerable cooling air flow virtually an active cooling system with which the increased thermal load capacity in this voltage range is reached is.

    Eine vorteilhafte Ausgestaltung der Erfindung sieht in diesem Zusammenhang außerdem die Merkmale

  • 2.1 der obere Kühlkörper weist nach Außen gerichtete, zentrisch und mittensymmetrisch angeordnete Kühlrippen auf,
  • 2.2 der untere Kühlkörper weist eine nach Außen gerichtete, kugelförmige Begrenzungskontur auf,
    • vor.
    Mit den nach Außen gerichteten Kühlrippen lassen sich im Hinblick auf die Oberflächenvergrößerung bekannter Maßen größere Wärmrmengen in der Zeiteinheit abführen.
    Die kugelförmigen Begrenzungskonturen der unteren Kühlkörper, die in gleicher Weise nach Außen gerichtet sind, gewährleisten durch die vergrößerten Abstände eine höhere Spannungssicherheit.An advantageous embodiment of the invention also sees the features in this context
  • 2.1 the upper heat sink has outwardly directed, centrally and centrally symmetrically arranged cooling fins,
  • 2.2 the lower heat sink has an outwardly directed, spherical boundary contour,
    • in front.
    With the cooling fins facing outwards, larger amounts of heat can be dissipated in the unit of time in view of the increase in surface area of known dimensions.
    The spherical boundary contours of the lower heat sinks, which are directed outwards in the same way, ensure greater voltage security due to the increased spacing.

    Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht die Merkmale

  • 3.1 der obere und der untere Kühlkörper sind jeweils mit zur Längachse des Schaltgerätes spiegelsymmetrich angeordneten Kühlkörperbefestigungen versehen,
  • 3.2 der obere und der untere Kontaktanschluß sind mit den freien Enden jeweils nach Außen gerichtet,
    • vor.
    Damit sind die Schaltgeräte zwischen den Polschalen sicher lösbar befestigt und darüber hinaus die oberen und unteren Kontaktanschlüsse mit weitem Abstand zueinander gut zugänglich.
    Die Erfindung wird durch ein figürlich dargestelltes Ausführungsbeispiel in drei Figuren näher erläutert, wobei die Figur 1 eine Vorderansicht auf den Seitenbereich des lediglich angedeuteten Schaltgerätes mit dem Innenbereich der Polschale zeigt, die
    Figur 2

    Figur 3
    nähere Einzelheiten des unteren Kühlkörpers erkennen läßt.
    A further advantageous embodiment of the invention sees the features
  • 3.1 the upper and the lower heat sink are each provided with heat sink fastenings arranged mirror-symmetrically to the longitudinal axis of the switching device,
  • 3.2 the upper and the lower contact connection are each directed towards the outside with the free ends,
    • in front.
    This means that the switching devices are securely detachably fastened between the pole shells and, moreover, the upper and lower contact connections are easily accessible with a large distance between them.
    The invention is explained in more detail by means of a figurative exemplary embodiment in three figures, with FIG. 1 showing a front view of the side region of the merely indicated switching device with the inner region of the pole shell, which

Zum besseren Verständnis ist das Schaltgerät VS in seiner Einbaulage zwischen dem oberen und unteren Kühlkörper KKo und KKu innerhalb einer Polschale mit dünner Zeichenlinie angedeutet. Um nähere Einzelheiten sichtbar zu machen, ist die zweite seitlich vorhandene Polschale in der Figur 1 nicht dargestellt. Innerhalb der Polschalen PS sind die Vakuumschütz-Befestigunsstege VB... vorgesehen, die zur Befestigung der oberen und unteren Kühlkörper KKo und KKu mittels der Kühkörperbefestigungen KB... dienen.
    Weiterhin ist angedeutet, daß das Schaltgerät VS am oberen Kühlkörper KKo mit der Vakuumschützbefestigung SB verbunden ist und der untere Kühlkörper KKu im wesentlichen die Lagefixierung des Schaltgerätes VS bewirkt. Der obere Kühlkörper KKo weist darüber hinaus den oberen Kontaktanschluß KAo auf, der im Einbauzustand zwischen den Polschalen PS - dargestellt ist, wie bereits erwähnt, in dieser Ansicht nur die hintere Polschale - zur Herstellung der elektrischen Verbindung frei zugänglich ist. Zur besseren Wärmeableitung ist der obere Kühlkörper KKo mit zum Vakuumschütz VS zentrisch angeordneten Kühlrippen KR... ausgestattet, die in ihrer Höhe von Innen nach Außen mit verringerter Oberflache entsprechend der anfallenden thermischen Belastung versehen sind. Zwischen den einzelnen Kühlrippen KR... sind die Lüftungsschlitze LS... angedeutet, aus denen der Kühlluftstrom KLS aus dem Schaltgerät VS herausgeführt wird.
    Unterhalb des lediglich angedeuteten Schaltgerätes VS ist der untere Kühlkörper KKu angeordnet, deren kugelförmige Begrenzungskontur BK sowie deren unterer Kontaktanschluß KAu - wie die Kühlrippen KR .. und deren oberer Kontaktanschluß KAo des oberen Kühlkörpers KKo - nach Außen gerichtet sind. Der untere Kühlkörper KKu ist im Umfangsbereich des Schaltgerätes VS mit mittensymmetrisch angeordneten Lufteintrittsöffnungen LE... derart versehen, daß sich zwischen dem unteren und dem oberen Kühlkörper der Kühlluftstrom KLS einstellt, der für eine ausreichende Wärmeabfuhr vom Schaltgerät VS im Zusammenhang mit den Kühlrippen KR .. des oberen Kühlkörpers KKo sorgt. Mit diesem durch Schlotwirkung entstehenden Kühlluftstrom KLS wird das Schaltgerät also aktiv gekühlt und ist somit für den höheren Spannungsbereich einsetzbar.    FIG. 1 shows the inside of the pole shell PS, to which the upper and lower contact connections KAo and KAu with the associated upper and lower heat sink KKo and KKu are screw-fastened by means of the respective heat sink attachment KB ... For better understanding, the switching device VS is indicated in its installation position between the upper and lower heat sink KKo and KKu within a pole shell with a thin line of characters. In order to make further details visible, the second side pole shell is not shown in FIG. 1. The vacuum contactor mounting webs VB ... are provided within the pole shells PS and are used to attach the upper and lower heat sinks KKo and KKu using the heat sink attachments KB ...
    Furthermore, it is indicated that the switching device VS on the upper heat sink KKo is connected to the vacuum contactor mounting SB and the lower heat sink KKu essentially fixes the position of the switching device VS. The upper heat sink KKo also has the upper contact connection KAo, which is shown in the installed state between the pole shells PS - as already mentioned, in this view only the rear pole shell - is freely accessible for establishing the electrical connection. For better heat dissipation, the upper heat sink KKo is equipped with cooling fins KR ... centrally arranged to the vacuum contactor VS, the height of which is provided from the inside to the outside with a reduced surface according to the thermal load. The ventilation slots LS ... between which the cooling air flow KLS is led out of the switching device VS are indicated between the individual cooling fins KR ...
    The lower heat sink KKu is arranged below the merely indicated switching device VS, the spherical delimitation contour BK and the lower contact connection KAu thereof - like the cooling fins KR .. and the upper contact connection KAo of the upper heat sink KKo - are directed outwards. The lower heat sink KKu is provided in the circumferential area of the switching device VS with center-symmetrically arranged air inlet openings LE ... in such a way that the cooling air flow KLS occurs between the lower and the upper cooling body, which ensures sufficient heat dissipation from the switching device VS in connection with the cooling fins KR. of the upper heat sink KKo. With this cooling air flow KLS resulting from the chimney effect, the switching device is actively cooled and can therefore be used for the higher voltage range.

    Die Figur 2 zeigt den oberen Kühlkörper KKo mit dem oberen Kontaktanschluß KAo mit Sicht auf den Bereich des unmittelbar angrenzenden, nicht dargestellten Schaltgerätes. Besonders zu erkennen ist hier die zentrische Anordnung eines Teils der Kühlrippen KR..., zwischen denen sich die Lüftungsschlitze LS befinden. Mitten- und spiegelsymmetrisch um die Vakuumschützbefestigung SB des oberen Kühlkörpers KKo sind die Kühlkörperbefestigungen KB... angeordnet. Desweiteren sind zur Versteifung und zur Oberflächenvergrößerung in den Randbereichen der oberen Kühlkörper KKo weitere Kühlrippen KR... vorgesehen.FIG. 2 shows the upper heat sink KKo with the upper one Contact connection KAo with a view of the immediate area adjacent switching device, not shown. Especially to Here you can see the central arrangement of part of the Cooling fins KR ..., between which the ventilation slots LS are located. Center and mirror symmetry around the vacuum contactor mounting SB of the upper heat sink KKo are the heat sink attachments KB ... arranged. Furthermore are for stiffening and to increase the surface area in the edge areas the upper heat sink KKo further cooling fins KR ... are provided.

    Die Figur 3 läßt nähere Einzelheiten des unteren Kühlkörpers KKu mit dem unteren Kontaktanschluß KAu durch Sicht auf die von dem Schalgerät abgewandte Außenseite erkennen. Hier ist in besondere Weise die Anordnung der Lufteintrittsöffnungen LE... neben dem ebenfalls hier nicht dargestellten Schaltgerät zu erkennen. Durch die seitliche mittensymmetrische Anornung der Lufteintrittsöffnungen LE... können diese zur Vergrößerung der sogenannten Schlotwirkung entsprechend groß ausgeführt sein, ohne das ein Stabilitätsverlust durch Querschnittverringungen auftreten kann.
    Wie die oberen Kühlkörper KKo (Fig.2) sind auch die unteren Kühlkörper KKu mitten- und spiegelsymmetrisch um das nicht dargestellte Schaltgerät angeordnet.    FIG. 3 reveals further details of the lower heat sink KKu with the lower contact connection KAu by looking at the outside facing away from the switching device. The arrangement of the air inlet openings LE ... in addition to the switching device, also not shown here, can be seen here in a special way. Due to the central symmetrical arrangement of the air inlet openings LE ..., they can be made large enough to increase the so-called chimney effect, without loss of stability due to cross-sectional reductions.
    Like the upper heat sinks KKo (Fig.2), the lower heat sinks KKu are arranged in the center and mirror symmetry around the switching device, not shown.
