Abstract
Description
Die Erfindung betrifft eine Berstscheibenanordnung für eine elektrische Schaltanlage nach dem Oberbegriff des Anspruches 1.The The invention relates to a rupture disc arrangement for an electrical switchgear according to the preamble of claim 1.
Wenn in einer elektrischen Schaltanlage, Niederspannungs- oder Mittelspannungsschaltanlage, aufgrund einer Störung ein Lichtbogen entsteht, dann wird durch den Lichtbogen das innerhalb der Schaltanlage befindliche Gas erhitzt, wodurch sich auch der Druck plötzlich erhöht. Dies kann dazu führen, dass das Gehäuse der elektrischen Schaltanlage explodiert, was für Bedienpersonen, die sich zufällig in dem Raum befinden, in dem die Schaltanlage steht, gefährlich auswirken kann.If in an electrical switchgear, low-voltage or medium-voltage switchgear, due to a fault an arc is created, then by the arc inside heated gas of the switchgear, which also causes the Pressure suddenly elevated. This can cause that the case the electrical switchgear explodes, causing operators who are themselves fortuitously in the room where the switchgear is located will be dangerous can.
Aus diesem Grunde besitzen solche Schaltanlagen so genannte Berstscheibenanordnungen, das sind Bereiche, in denen Wandabschnitte mit geringerer Festigkeit angeordnet sind, die ein gezieltes Ausströmen der heißen Gase ermöglichen. Diese Berstscheibenanordnungen können insbesondere dort vorgesehen sein, zum Beispiel an der Deckwand, wo durch das Ausströmen des heißen Gases eine Gefährdung von Personen vermieden ist.Out For this reason, such switchgear have so-called rupture disc arrangements, the are areas where wall sections with lower strength are arranged, which allow a targeted outflow of hot gases. These rupture disc arrangements can especially be provided there, for example on the top wall, where by the outflow of the hot Gases a hazard avoided by persons.
Es ist eine Berstscheibenanordnung bekannt geworden, bei der die Berstscheibe in einen Ring aus Kunststoff eingesetzt ist, der unter Zwischenfügung einer Dichtung gegen die Wandung der Schaltanlage angelegt und daran festgeschraubt wird. Dieser Kunststoffring besitzt zwar ausreichende Festigkeit; der Kunststoff hat aber die Eigenschaft, zu fließen, so dass die Verbindung zwischen dem Gehäuse der Schaltanlage und der Berstscheibenanordnung und damit die Dichtigkeit verschlechtert werden.It is a rupture disc arrangement has become known in which the rupture disc Inserted in a ring of plastic, the interposition of a Gasket against the wall of the switchgear and screwed tight becomes. Although this plastic ring has sufficient strength; of the But plastic has the property to flow, so the connection between the case the switchgear and rupture disk assembly and thus the tightness be worsened.
Aufgabe der Erfindung ist es, eine Berstscheibenanordnung der Eingangs genannten Art zu schaffen, bei der eine Verschlechterung der Dichtigkeit vermieden ist.task The invention is called a rupture disc arrangement of the input To create a type in which a deterioration of the tightness avoided is.
Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruches 1.These The object is achieved by the features of claim 1.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Further advantageous embodiments of the invention are the dependent claims remove.
Anhand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung dargestellt ist, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile näher erläutert und beschrieben werden.Based the drawing in which an embodiment the invention is shown, the invention and others advantageous embodiments and improvements of the invention and more advantages closer explained and described.
