Description

Elektrischer Stromunterbrecher Die Erfindung bezieht sich auf elektrische Stromunterbrecher, wie Schaltrohre bzw. Schaltstifte für elektrische Gasschalter, Hochspannungsausblasesicherungen, Röhrenfunkenstrecken o. dgl, bei dellen das zur Lichtbogenlö schung benötigte Löschgas durch den Ahschaltlichtbogen selbst aus den gasa@gebenden Schaltraumwandungen erzeugt wird.Electrical Circuit Breaker The invention relates to electrical Circuit breakers, such as switching tubes or switching pins for electric gas switches, High-voltage blowout fuses, tube spark gaps or the like, in the case of dents Arc extinguishing required extinguishing gas through the switching arc itself from the gasa @ giving control room walls is generated.

Die bisher zum Aufbau derartiger Stromunterbrecher bekannten Stolle. wie Fiber. Borsäure. Kunstharze auf Harnstoffbasis o). tdgl., erfüllen jedoch die verschiedenartigen Allforderungen nur zum Teil. So weist z. L. Fiber starke Formätnd@rungeln in feuchter Atnmosphltäre auf, während Borsäure nur eilte geringe mechanische Festigkeit besitzt. Die Kunstharze auf Harnstoffbasis lassen sich nicht leicht bearbeiten und weisen gleichfalls keilte hinreichende mechanische Festigkeit auf.The studs known up to now for the construction of such circuit breakers. like fiber. Boric acid. Urea-based synthetic resins o). daily, but meet the various universal demands only in part. So z. L. Fiber strong moldings in a moist atmosphere, while boric acid hastened only low mechanical strength owns. The urea-based synthetic resins are not easy to work and also have wedges of sufficient mechanical strength.

Die Erfindung besteht demgegenüber in der Verwendung von vulkanisierten Mischpolymnerisaten als Schaltraummaterial. Diese erfindungsgemäßen Mischpolymerisate erfüllen g@genülbetr den bisher bekannten und vorgeschlag@nen Stoffen gleichzeitig alle Anforderungen. die an das für die gasabgebenden Schaltraumwandungen v@rwendete Material gestellt w@rden müssen, zumal es sich beine @rfindungsgetmäß5en Material nicht um ein thermoplastisches, sondern um ein elastisches i\Iaterial handalt- Ferner zeigt das erlindungsgem @ße Material innerhalb der lpraktisclh in Frag@ k@mmenden Tlimp@raturgrenzen k@in@rlci V@rantuderungen hinsichtlich seiner nie-@hallischen Eigensclh@ttent in der Wärme wie auch in der halte @o daß beispielsweise bei den auttr@tenden B@trielhtempcertern @etwa 7o @ . kein Fli@ßen des Ma@erials statttindet.In contrast, the invention consists in the use of vulcanized Mixed polymers as switch room material. These copolymers according to the invention meet the requirements of the previously known and proposed substances at the same time all requirements. the one used for the gas-emitting control room walls Material must be provided, especially since it is based on the invention not a thermoplastic, but an elastic material shows that according to the invention @ ße material within the practice in Ask @ k @ mmenden Tlimp @ raturgrenzen k @ in @ rlci opinions regarding his Dutch property in warmth as well as in hold @o that for example at the auttr @ tenden B @ trielhtempcertern @ about 7o @. no flowing of the material takes place.

Eine besonders nute Anpassungsmöglichkeit ergibt sich gemäß der weiteren Erindung durch die Verwendung eines Mlischpolymerisates, das Butad@en als Komponente enthält bzw. durch die Verwendung eines Misch-@olymerisates aus Buta@ien und Acry1säurenitrll.A particularly good customization option arises according to the other Invention through the use of a mixed polymer, the butad @ en as a component contains or through the use of a mixed @ olymers of buta @ ien and Acry1säurenitrll.
