Abstract

The invention relates to a switchgear cabinet comprising a framing (1) and covering parts (2, 3, 4) provided in the form of lateral walls, a rear wall, a sheet steel top, etc. A protective system provided for suppressing interferences caused by electromagnetic radiation is formed by film pieces (5, 6, 10) which are arranged between the framing (1) and the covering parts (2, 3, 4). The film pieces are electrically conductive and are fastened to the framing using common adhesive tapes before the covering parts are applied. The described construction of a switchgear cabinet permits a high degree of electromagnetic compatibility (EMV) while using few materials and less work time.

Schaltschrank mit einer Schutzeinrichtung gegen elektromagnetische StrahlungControl cabinet with a protective device against electromagnetic radiation
Die Erfindung betrifft einen Schaltschrank mit einem Gerüst und das Gerüst abdeckenden Umhüllungsteilen sowie mit einer Schutzeinrichtung gegen Störungen durch elektromagnetische Strahlung. Ein Schaltschrank dieser Art ist beispielsweise durch die EP 0 529 748 Bl oder die EP 0 528 240 AI bekanntgeworden.The invention relates to a control cabinet with a scaffold and the covering parts covering the scaffold and with a protective device against interference from electromagnetic radiation. A control cabinet of this type has become known, for example, from EP 0 529 748 B1 or EP 0 528 240 AI.
Die erwähnte Schutzeinrichtung hat die Aufgabe, einerseits das Austreten einer elektromagnetischen Strahlung aus dem Schaltschrank in die Umgebung zu verhindern, um Störungen anderer Geräte oder Anlagen zu vermeiden. Andererseits soll auch das Eindringen einer in der Umgebung vorhandenen störenden elektromagnetischen Strahlung in einen Schaltschrank verhindert werden, damit darin befindliche Geräte und Ausrüstun- gen nicht beeinflußt werden können. Die Beständigkeit gegen störende Einflüsse der beschriebenen Art wird als „elektromagnetische Verträglichkeit" (EMV) bezeichnet. Die möglichen Quellen einer störenden elektromagnetischen Strahlung sind vielfältig: es können beispielsweise Schaltlichtbö- gen von energietechnischen Schaltgeräten wie Schützen oderThe protective device mentioned has the task, on the one hand, of preventing electromagnetic radiation from escaping from the control cabinet into the environment in order to avoid interference with other devices or systems. On the other hand, the penetration of a disturbing electromagnetic radiation in the environment into a control cabinet is also to be prevented, so that devices and equipment located therein cannot be influenced. The resistance to interfering influences of the type described is referred to as "electromagnetic compatibility" (EMC). The possible sources of interfering electromagnetic radiation are diverse: for example, switching arcs from energy-related switching devices such as contactors or
Leistungsschaltern sein, ferner Geräte mit Leistungshalbleitern, insbesondere wenn diese im Teillastbetrieb arbeiten. Weitere Verursacher hochfrequenter Störungen sind alle Betriebsmittel, die ohnehin im Hoch- oder Höchstfrequenzbereich arbeiten, wie Mikroprozessoreinrichtungen und Sender. Die von solchen Einrichtungen ausgehenden Strahlungen können insbesondere benachbarte elektronische Anlagen beeinflussen, indem sie fehlerhafte oder ungewollte Reaktionen hervorrufen. An sich stellen die zum Bau von Schaltschränken eingesetztenBe circuit breakers, also devices with power semiconductors, especially if they work in partial load operation. Other sources of high-frequency interference are all equipment that works in the high or high frequency range anyway, such as microprocessor devices and transmitters. The radiation emitted by such devices can in particular influence neighboring electronic systems by causing incorrect or unwanted reactions. As such, they are used to build control cabinets
Materialien, beispielsweise Stahlblech mit einer Dicke von zwei mm, eine wirksame Barriere gegen den Durchtritt einer störenden elektromagnetischen Strahlung dar. Jedoch gibt es aus konstruktiv unvermeidbaren Gründen an Schaltschränken zahlreiche Stellen, an denen die Umhüllungsteile nicht direkt auf dem Gerüst aufliegen oder an denen betriebsbedingte Spalte vorhanden sind, wie an Türen. Durch solche Spalte können insbesondere hoch- und höchstfrequente Strahlungen (Mega- und Gigahertz-Bereich) hindurchtreten. Daher wurde bisher der Weg beschritten, solche Spalte gezielt strahlungssicher abzudichten, beispielsweise durch elektrisch leitfähige Türdichtungen aus elastischem Metallgewebe oder leitfähigem kompres- siblem Kunst- bzw. Schaumstoff. Diese gezielte Anbringung von Dichtungsmaterial erfordert ein sorgfältiges Arbeiten und ist stets mit der Unsicherheit verbunden, daß einzelne mögliche Durchtrittsstellen für störende Strahlungen übersehen werden.Materials, for example sheet steel with a thickness of two mm, represent an effective barrier against the passage of interfering electromagnetic radiation. However, for constructional inevitable reasons, there are numerous places on switch cabinets where the covering parts do not lie directly on the scaffolding or where there are operational gaps are present, such as on doors. High-frequency and ultra-high-frequency radiation (mega and gigahertz range) can pass through such gaps. For this reason, the path has so far been taken to seal such gaps in a radiation-proof manner, for example by means of electrically conductive door seals made of elastic metal fabric or conductive, compressible plastic or foam. This targeted application of sealing material requires careful work and is always associated with the uncertainty that individual possible passages for disruptive radiation are overlooked.
Der Erfindung liegt hiervon ausgehend die Aufgabe zugrunde, eine einfache und zuverlässige sowie preiswerte Schutzeinrichtung gegen Störungen durch elektromagnetische Strahlung zu schaffen. Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Schutzeinrichtung wenigstens ein biegsames Folienstück aus einer elektrisch leitfähigen Kunststoffolie aufweist, und daß das Folienstück zwischen dem Gerüst und den Umhüllungsteilen angeordnet ist. Die Verwendung einer Folie hat den Vorteil, daß grundsätzlich eine vollständige EMV-Ab- schirmung bzw. Abdichtung eines Schaltschrankes erzielt wird. Es ist daher ausgeschlossen, daß kritische Bereiche oder sy- stembedingte Öffnungen, z.B. Schraubenlöcher, übersehen werden- Sofern aber Öffnungen benötigt werden, z.B. für Lüftungsgitter oder Durchführungen für Leitungen, so lassen sich diese auf einfachste Weise durch Aufschneiden des Folienstük- kes herstellen. Da folienartige Kunststoffe, auch in elek- trisch leitfähiger Ausrüstung, preiswert erhältlich sind, stellen sie im Vergleich zu den bisherigen Mitteln eine günstige Alternative dar.Proceeding from this, the object of the invention is to create a simple, reliable and inexpensive protective device against interference from electromagnetic radiation. This object is achieved according to the invention in that the protective device has at least one flexible piece of film made of an electrically conductive plastic film and that the piece of film is arranged between the frame and the covering parts. The use of a film has the advantage that a complete EMC shielding or sealing of a control cabinet is basically achieved. It is therefore impossible for critical areas or system-related openings, eg screw holes, to be overlooked. However, if openings are required, for example for ventilation grilles or lead-throughs for cables, these can be produced in the simplest way by cutting open the piece of film. Since film-like plastics, also in electrically conductive equipment, are available inexpensively, they represent a cheap alternative to the previous means.
Schaltschränke weisen in der Regel wenigstens ein bewegbares Umhüllungsteil in der Gestalt einer Tür für den Zugang zum Innenraum auf. Damit auch hier die gewünschte EMV-Dichtigkeit besteht, kann das Folienstück für den gesamten Umfang des Gerüstes einschließlich der Tür bemessen sein, derart, daß das Folienstück an der Scharnierseite der Tür vom Gerüst auf die Tür übertritt. Leichter herstellbar sein kann die EMV-Abdich- tung nach einer Ausgestaltung der Erfindung jedoch dadurch, daß bei einem Schaltschrank mit einer durch ein bewegbares Umhüllungsteil zu verschließenden Zugangsöffnung wenigstens ein erstes Folienstück die Zugangsöffnung freilassend ange- ordnet ist und daß wenigstens ein gesondertes zweites Folienstück vorgesehen ist, das mit dem ersten Folienstück wenigstens örtlich elektrisch leitend verbunden ist.Control cabinets generally have at least one movable covering part in the form of a door for access to the interior. So that the desired EMC tightness also exists here, the film piece can be dimensioned for the entire circumference of the scaffold including the door, in such a way that the film piece on the hinge side of the door passes from the scaffold to the door. According to one embodiment of the invention, however, the EMC seal can be easier to manufacture in that, in the case of a switchgear cabinet with an access opening to be closed by a movable covering part, at least a first piece of film is arranged leaving the access opening free and that at least one separate second piece of film is provided is, which is at least locally electrically connected to the first piece of film.
Bei der Anbringung der Folienstücke am Gerüst und/oder Umhül- lungsteilen eines Schaltschrankes kann nicht ausgeschlossen werden, daß es zu einer Beschädigung kommt, die den angestrebten Schutz gegen elektromagnetische Strahlung örtlich beeinträchtigt. Diesem möglichen Einfluß kann dadurch entgegengewirkt werden, daß jeweils zwei oder mehr Folienstücke übereinander angeordnet werden, insbesondere in einer überlappenden Anordnung.When the film pieces are attached to the scaffolding and / or the covering parts of a control cabinet, it cannot be ruled out that damage will occur which locally impairs the desired protection against electromagnetic radiation. This possible influence can be counteracted by arranging two or more pieces of film one above the other, in particular in an overlapping arrangement.
Zu einem verringerten Arbeitsaufwand für die Herstellung der Schutzausrüstung eines Schaltschrankes kann ferner dadurch beigetragen werden, daß die Folienstücke aus einem unter dem Einfluß von Wärme schrumpfbaren Material bestehen. Es ist dann nämlich unerheblich, ob beim Anbringen der Folienstücke am Gerüst oder an den Uhüllungsteilen des Schaltschrankes Falten oder ähnliche Unregelmäßigkeiten auftreten, weil diese durch die anschließende Anwendung von Wärme, z. B. Heißluft, problemlos geglättet werden können.A reduced amount of work for the production of protective equipment for a control cabinet can also be contributed by the fact that the film pieces consist of a material that can be shrunk under the influence of heat. It is then irrelevant whether folds or similar irregularities occur when the film pieces are attached to the frame or to the covering parts of the control cabinet because these by the subsequent application of heat, e.g. B. hot air, can be smoothed easily.
Die Erfindung wird im folgenden anhand eines in den Figuren dargestellten Ausführungsbeispieles näher erläutert.The invention is explained below with reference to an embodiment shown in the figures.
Die Figur 1 zeigt in einer schematisch vereinfachten perspektivischen Darstellung ein Gerüst eines Schaltschrankes mit einem Folienstück und mehreren Umhüllungsteilen.FIG. 1 shows a schematically simplified perspective illustration of a framework of a control cabinet with a piece of film and a plurality of covering parts.
In der Figur 2 ist im Schnitt eine Einzelheit im Bereich einer Zugangsöffnung eines Schaltschrankes gezeigt.A detail in the area of an access opening of a control cabinet is shown in section in FIG.
Das in der Figur 1 gezeigte Gerüst 1 eines Schaltschrankes kann einen beliebigen geeigneten Aufbau besitzen, da die Erfindung unabhängig von der Beschaffenheit des Gerüstes 1 anwendbar ist. Vorzugsweise wird das Gerüst 1 jedoch mit Rücksicht auf eine hohe Unterdrückung störender elektromagnetischer Strahlungen aus Stahlblechteilen bestehen. Im Unter- schied zu Schaltschränken einer üblichen Bauart werden in der Figur 1 angedeutete sowie eine Umhüllungsteile 2, 3 und 4 (Seitenwände, Rückwand und Dachblech) nicht direkt an dem Gerüst 1 befestigt, sondern unter Zwischenlage biegsamer und elektrisch leitfähiger Folienstücke 5 und 6. Von diesen um- schließt das Folienstück 5 das Gerüst 1 etwa U-förmig, während das Folienstück 6 im wesentlichen eben und dem als Dachblech ausgebildeten Umhüllungsteil 4 zugeordnet ist. Eine Zugangsöffnung 7 an der Frontseite des Gerüstes 1 ist in der Figur 1 ohne Umhüllungsteil und ohne Folienstück gezeigt, da betreffende Einzelheiten dieses Zugangsbereiches näher in der Figur 2 dargestellt sind.The scaffold 1 of a control cabinet shown in FIG. 1 can have any suitable structure, since the invention can be used regardless of the nature of the scaffold 1. However, the scaffold 1 is preferably made of sheet steel parts with a view to a high suppression of disturbing electromagnetic radiation. In contrast to control cabinets of a customary type, sheathed parts 2, 3 and 4 (side walls, rear wall and roof panel) indicated in FIG. 1 are not fastened directly to the frame 1, but with flexible and electrically conductive film pieces 5 and 6 interposed. Of these, the piece of film 5 encloses the frame 1 approximately U-shaped, while the piece of film 6 is essentially planar and is assigned to the covering part 4 designed as a roof plate. An access opening 7 on the front of the scaffold 1 is shown in FIG. 1 without a covering part and without a piece of film, since the relevant details of this access area are shown in more detail in FIG.
Das Beispiel gemäß der Figur 2 geht davon aus, daß ein Folienmaterial mit einer hochfrequenzleitenden Beschichtung verwendet wird. Das hieraus bestehende erste Folienstück 5 ist an der Stirnseite des Gerüstes 1 mittels eines doppelseitigen Klebebandes 8 befestigt. Durch die Bemessung des Folienstückes 5 ist dafür gesorgt, daß ein überstehendes Endstück 9 verbleibt. An der Seitenfläche des Gerüstes 1 ist das überstehende um 180° umgelegte Endstück 9 gleichfalls mittels eines doppelseitigen Klebebandes 8 befestigt. Ein der Zugangsseite des Schaltschrankes zugeordnetes zweites Folienstück 10 liegt überlappend auf dem Endstück 8 auf und ist mittels eines Klebebandes 11 an der Seitenfläche des Gerüstes 1 befestigt. Je nach der Gestaltung eines die Frontseite des Schaltschrankes verschließenden bewegbaren Umhüllungsteiles kann das Folienstück 10 dieses Umhüllungsteil ganz oder teilweise bedecken.The example according to FIG. 2 assumes that a film material with a high-frequency conductive coating is used. The first piece of film 5 consisting of this is attached to the end face of the frame 1 by means of a double-sided adhesive tape 8. The dimensioning of the film piece 5 ensures that a protruding end piece 9 remains. On the side surface of the scaffold 1, the projecting end piece 9, which is folded over by 180 °, is also fastened by means of a double-sided adhesive tape 8. A second film piece 10 assigned to the access side of the control cabinet lies overlapping on the end piece 8 and is fastened to the side surface of the frame 1 by means of an adhesive tape 11. Depending on the design of a movable wrapping part which closes the front of the control cabinet, the piece of film 10 can cover this wrapping part in whole or in part.
Wie bereits erwähnt, eignet sich für die Zwecke der Erfindung insbesondere ein Folienmaterial mit einer hochfrequenzleitenden Beschichtung. Jedoch sind auch Kunststoffolien aus elek- trischleitfähigem Kunststoff erhältlich, die somit insgesamt elektrisch leitfähig sind und daher beidseitig durch Berüh- rung mit anderen leitfähigen Teilen zu kontaktieren sind.As already mentioned, a film material with a high-frequency conductive coating is particularly suitable for the purposes of the invention. However, plastic films made of electrically conductive plastic are also available, which are thus electrically conductive overall and are therefore to be contacted on both sides by contact with other conductive parts.
In dem Beispiel gemäß der Figur 1 wird davon ausgegangen, daß Folien mit einer der Höhe üblicher Schaltschränke entsprechenden Breite verfügbar sind. Sollten die Folien schmaler sein, können zwei oder mehr daraus gefertigte Folienstücke verwendet werden, um das Gerüst zu bedecken.In the example according to FIG. 1, it is assumed that foils are available with a width corresponding to the height of conventional control cabinets. If the films are narrower, two or more pieces of film made from them can be used to cover the framework.
Gut geeignet für die Zwecke der Erfindung ist ferner eine schrumpffähige Ausrüstung der Folien. Diese Eigenschaft er- möglicht nach dem Anbringen der Folienstücke am Gerüst mittels Klebestreifen durch Wärmeanwendung eine gewisse Glättung und Straffung, wodurch die Folienstücke zur Anlage am Gerüst gebracht werden. Also suitable for the purposes of the invention is a shrinkable finishing of the films. This property enables a certain smoothing and tightening after application of the film pieces to the scaffold by means of adhesive strips by applying heat, whereby the film pieces are brought into contact with the scaffold.
