Abstract

The vibration-resistant cabinet or box, for electrical equipment, is designed to withstand earthquakes, and similar shocks and accordingly has a resonant frequency greater than 10 Hz. It allows access for servicing from the front and/or rear despite the effects of vibration. Diagonal struts (5) form an X linking the four corners of the cabinet's frame. The struts are pivoted about vertical axes (a, a') at the frame's corners and are rigidly locked together (8) at their crossover point.

Description

Vorrichtung an SchaltschränkenDevice on control cabinets

Die Erfindung bezieht sich auf eine Vorrichtung an im wesentlichen aus einem Profilrahmengestell und darauf befestigten Blechplatten bestehenden Schaltschrank zur Aufnahme elektrischer oder elektronischer Baugruppen mit Türen auf Vorder- und/oder Rückseite.The invention relates to a device at substantially Control cabinet consisting of a profile frame and sheet metal plates attached to it to accommodate electrical or electronic assemblies with doors on the front and / or Back.

Derartige Schaltschränke finden hauptsächlich Verwendung zur kompakten Anordnung von elektronischen Baugruppen', die in Einschüben zusammengefaßt, mit elektrischen Verbindungsmitteln an die üblicherweise auf der Rückseite des Schranks befindlichen Schaltmittel der Verdrahtungsebene anschließbar sind.Such cabinets are mainly used for compact Arrangement of electronic assemblies', which are combined in inserts, with electrical connection means to the usually on the back of the cabinet located switching means of the wiring level can be connected.

Schaltschränke, wie auch Schalttafeln und Schaltpulte stellen mechanisch schwingungsfähige Systeme dar, deren Eigen- oder Resonanzfrequenz in der Größenordnung von einigen Hertz liegt.Control cabinets, as well as control panels and control panels, provide mechanical systems capable of oscillation, whose natural or resonance frequency is of the order of magnitude of a few Hertz.

In Katastrophenfällen (Erdbeben; Flugzeugabsturz) kann es vorkommen, daß auf derartige Schränke, die fest mit dem Untergrund verbunden sind, Schwingungen niedriger Frequenz und hoher Ampli tude um eine oder mehrere der drei Raumachsen übertragen werden, die, wenn sie in den Eigenresonanz>ereich des Schranks fallen, zu plastischen Verformungen dc fi ranks, zurBeschädigung seines Inhalts und der zu diesem führenden elektrischen Verbindungen führen können.In the event of a disaster (earthquake; plane crash) it can happen that on such cabinets, which are firmly connected to the ground, vibrations low frequency and high amplitude around one or more of the three spatial axes which, if they fall within the natural resonance range of the cabinet, to plastic deformation of dc fi ranks, to damage to its contents and the can lead to this leading electrical connections.

Für Schaltschränke, die in erdbebengefährdeten Gebieten Verwendung finden sollen, sind deshalb Prüfungen auf Erdbebenbestän- digkeit vorgeschrieben, durch welche nachzuweisen ist, daß ihre --en-.equenz oberhalb 10 bzw. 15 Hz liegt und daß auch bei Beschleunigungen bis zu 1 g die Funktion der mechanischen und elektrischen Teile gewährleistet bleibt und keine plastischen Verformungen auftreten.For control cabinets that are used in earthquake-prone areas should find, therefore tests for earthquake resistance age prescribed by which it is to be proven that their --en-. sequence above 10 or 15 Hz and that the function of the mechanical also at accelerations of up to 1 g and electrical parts are guaranteed and no plastic deformation occurs.

5 besteht demgemäß die Aufgabe, serienmäßige Schaltschränke der eingangs genannten Art mit möglichst einfachen Mitteln so zu versteifen, daß die Eigenfrequenz des schwingungsfähigen Systems "Schaltschrank' größer 10 Hz ist, wobei die Zugänglichkeit zum Schrankinhalt zu Nartungs- oder Schaltzwecken über Vorder-und/oder Rückseite des Schranks erhalten bleiben muß. 5 is accordingly the task of standard control cabinets of the initially to stiffen said type with the simplest possible means so that the natural frequency of the vibratory system "control cabinet" is greater than 10 Hz, whereby the accessibility to the contents of the cabinet for maintenance or switching purposes via the front and / or back of the cabinet must be preserved.

ine Lösung dieser Aufgabe wird in einer Vorrichtung gesehen, die dadurch gekennzeichnet ist, daß aus jeweils zwei einen stumpfen Winkel einschließenden Profilstäben gebildete Winkelstreben mit den Enden ihre Schenkel bei den oberen und unteren Sckpunkten des Schrankrahmens auf dessen Rück- und/oder Vorderseite um senkrechte Achsen schwenkbar befestigt sind und daß die Winkelstreben paarweise mittels eines an ihren Scheiteln angreifenden Spannverschlusses kraft- und formschlüssig verbindbar sind.A solution to this problem is seen in a device that thereby is characterized in that each two profile bars enclosing an obtuse angle formed angled struts with the ends of their legs at the upper and lower vertexes the cabinet frame can be pivoted about vertical axes on its rear and / or front side are attached and that the angle struts in pairs by means of a at their apices attacking toggle fastener are non-positively and positively connectable.

Mit dieser Vorrichtung wird eine sehr wirksame Diagonalversteifung des Schrankrahmengestells erzielt, wobei gleichzeitig durch die Auftrennmöglichkeit des Knotens der Diagonalstreben die gute Zugänglichkeit des Schrankes gewährleistet wird.This device is a very effective diagonal stiffener of the cabinet frame achieved, while at the same time by the possibility of separation the knot of the diagonal struts ensures good accessibility of the cabinet will.

Zur Erläuterung der Erfindung ist in den Figuren 1 und 2 ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung an Schaltschränken schematisch dargestellt und im folgenden beschrieben.An exemplary embodiment is shown in FIGS. 1 and 2 to explain the invention the device according to the invention shown schematically on control cabinets and described below.

Der in Figur 1 in einer Ansicht von vorne und in Figur 2 in einer Ansicht von oben dargestellte Schaltschrank besteht im wesentlichen aus einem quaderförmigen Profilrahmengestell 1, welches mit hier nicht im einzelnen gezeichneten Blechplatten 2 verkleidet ist. Vorder- und Rückseite des Schranks sind mit zweiflügeligen Türen 3 verschließbar, die in Figur 1 der Ubersichtlichkeit halber nur angedeutet sind. Da die Türen 3 wenig zur Versteifung der übrigen, einen Kastenrahmen bildenden Schrank- teile beitragen können, sind Winkelstreben 4 vorgesehen, die paarweise an Vorder- und Rückfront des Schaltschranks angeordnet Diagonalversteifungen bilden.The in Figure 1 in a view from the front and in Figure 2 in a The switchgear cabinet shown from above consists essentially of a cuboid Profile frame 1, which is not shown here in detail with sheet metal plates 2 is disguised. The front and back of the cabinet have double doors 3 closable, which are only indicated in Figure 1 for the sake of clarity. Since the doors 3 do little to stiffen the rest of the cabinet, which forms a box frame share can contribute, angled struts 4 are provided, which are in pairs at the front and Diagonal stiffeners are arranged at the rear of the control cabinet.

Die Winkelstreben 4 bestehen aus jeweils zwei, einen stumpfcn nkel einsch]ießenden Profilstäben 5. Die Enden 6 der die inkelstrebenschenkel bildenden Stäbe 5 sind bei den oberen unc unteren Eckpunkten des Schrankrahmens 1 auf dessen Rück- und/ode.The angle struts 4 each consist of two, one obtuse nkel including profile rods 5. The ends 6 of the legs forming the incisal strut Rods 5 are at the upper and lower corners of the cabinet frame 1 on it Return and / ode.

Vorderseite um senkrechte Achsen a - a' schwenkbar mit diesen verbunden.Front about vertical axes a - a 'pivotally connected to these.

Zur ITerstellung einer Diagonalverstrebung ist an den sich In eingeschwenkter Lage gegenüberstehenden Scheiteln 7 eines Paares von Winkelstreben 4 ein Spannverschluß 8 vorgesehen, der die Winkelstreben 4 kraft- und formschlüssig verbirldel.To create a diagonal bracing, the In is swiveled in Position of opposite vertices 7 of a pair of angle struts 4 a tension lock 8 provided, which verbirldel the angled struts 4 non-positively and positively.
