Description

Schaltanlaqenleistunqskontakt und Leistunqskontaktisolierunq  Switching circuit power contact and power contact isolation
Beschreibung description
Die Erfindung betrifft einen Schaltanlagenleistungskontakt für eine Schaltanlage, insbesondere eine Niederspannungsschaltanlage mit eine Leistungskontaktisolierung gemäß dem Oberbegriff des Anspruchs 1. The invention relates to a switchgear power contact for a switchgear, in particular a low-voltage switchgear with a power contact insulation according to the preamble of claim 1.
In bekannten Kontaktsystemen sind in aller Regel Kontaktelemente eingesetzt, die in ein Kupfer oder Messingelement eingelegt werden. Der Stromfluss erfolgt hauptsächlich über das Kontaktelement, kann aber unter Umständen auch vom jeweiligen Kontaktpin auf den Buchsen Körper direkt übertragen werden, was bei Nennstrom eher unproblematisch ist. In known contact systems contact elements are used as a rule, which are inserted into a copper or brass element. The current flow takes place mainly via the contact element, but may also be transmitted directly from the respective contact pin on the sockets body, which is rather unproblematic at rated current.
Nachteilig kann es bei derartigen Anordnungen, im Falle eines Kurzschlusses jedoch zu einem vergleichsweise hohen Stromfluss kommen, welcher auch eine dynamische Bewegung des jeweiligen Kontaktpins oder der jeweiligen Kontaktbuchse verursachen kann. Diese Bewegung kann dazu führen, dass es zu einem elektrischen Kontakt zwischen Pin und Buchse außerhalb des Kontaktelementes kommen kann. Da der Strom im Kurzschlussfall vergleichsweise hoch ausfallen, führt dies unter Umständen zu einer mechanischen und elektrischen Beschädigung auf beziehungsweise Pin und Buchse, was wiederum deren Kontaktverhalten nachteilig beeinflussen und verändern kann. However, a disadvantage of such arrangements, in the case of a short circuit, may be a comparatively high current flow, which may also cause a dynamic movement of the respective contact pin or the respective contact socket. This movement can lead to an electrical contact between pin and socket outside of the contact element. Since the current in the short circuit case comparatively high, this may lead to mechanical and electrical damage or pin and socket, which in turn can adversely affect their contact behavior and change.
Vorgenannte Nachteile zu überwinden stellt sich der Erfindung die Aufgabe ein verbessertes Leistungskontaktelement für eine Schaltanlage anzugeben, bei welchem im Falle eines Kurzschlusses eine mechanischen und/oder elektrische Beschädigung von Kontaktpin oder Kontaktbuchse weitestgehend vermieden wird. Diese Aufgabe wird gelöst durch einen Leistungskontakt für eine Schaltanlage, insbesondere eine Niederspannungsschaltanlage, mit den Merkmalen des Anspruchs 1 . Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sowie eine Leistungskontaktisolierung und Schaltanlage, insbesondereTo overcome the aforementioned disadvantages, the invention has the object to provide an improved power contact element for a switchgear, in which in the case of a short circuit, a mechanical and / or electrical damage of Kontaktpin or contact socket is largely avoided. This object is achieved by a power contact for a switchgear, in particular a low-voltage switchgear, with the features of claim 1. Advantageous embodiments and further developments of the invention as well as a power contact insulation and switchgear, in particular
Niederspannungsschaltanlage, mit wenigstens einem solchen Leistungskontakt sind in weiteren Ansprüchen und der nachfolgenden Beschreibung angegeben. Low-voltage switchgear, with at least one such power contact are specified in further claims and the following description.
Demgemäß weist der erfindungsgemäße Schaltanlagen-Leistungskontakt eine wenigstens eine Isolierschicht in der Art wenigstens eines elektrischen Isolierelementes innerhalb der Kontaktbuchse und/oder außen auf dem Kontaktpin auf, welches im Falle einer relativen Bewegung von Kontaktpin und Kontaktbuchse verhindert, dass Strom außerhalb des dafür vorgesehenen Kontaktelementes fließt und den Stromfluss auf das Kontaktelement begrenzt. Accordingly, the switchgear power contact according to the invention has at least one insulating layer in the manner of at least one electrical insulating element within the contact socket and / or on the outside of the contact pin, which prevents in the case of a relative movement of Kontaktpin and contact socket that current flows outside the designated contact element and limits the current flow to the contact element.
Somit wird auch im Falle einer dynamischen Bewegung garantiert, dass der Strom nur über das Kontaktelement fließt und eine Beschädigung an Pin oder Buchse verhindert ist. Thus, even in the case of a dynamic movement is guaranteed that the current flows only through the contact element and damage to pin or socket is prevented.

Auch ist vorsehbar, dass die Isolierung mittels eines partiell unterbrochenen Körpers, beispielsweise mittels Noppen oder Schlitzung, bewirkt ist, so dass nicht zwingend eine geschlossene Isolierschicht ausgebildet sein muss. It is also conceivable that the insulation is effected by means of a partially interrupted body, for example by means of knobs or slits, so that it is not absolutely necessary for a closed insulating layer to be formed.
Vorteilhaft sind als Isolationsmedien dabei sowohl aus Kunststoff in Form von Festkörper oder Folie gebildete Medien sowie in zunächst flüssiger Form vorliegenden Medien wie Lacke oder Laminierungen und dergleichen vorsehbar. It is advantageous as isolation media both plastic in the form of solid or foil formed media as well as initially liquid form present media such as paints or laminations and the like providable.
