Stromdurchführvorrichtunq für hohe Drücke und TemperaturenCurrent carrying device for high pressures and temperatures
Die Erfindung betrifft eine Stromdurchführvorrichtung, die für Drücke und Temperaturen von mehreren tausend bar bzw. Kelvin ausgelegt ist.The invention relates to a Stromdurchführvorrichtung, which is designed for pressures and temperatures of several thousand bar or Kelvin.
Aus dem Stand der Technik sind Stromdurchführvorrichtungen für sehr hohe Temperaturen - diese kommen beispielsweise bei Kraftfahrzeug-Zündkerzen zur Anwendung - sowie Stromdurchführvorrichtungen für sehr hohe Drücke bekannt.Current carrying devices for very high temperatures - these are used, for example, in motor vehicle spark plugs - and Stromdurchführvorrichtungen for very high pressures are known from the prior art.
Eine Vielzahl dieser Anwendungsfälle beinhaltet lediglich eine der beiden Problemstellungen - also entweder "hoher Druck" oder "hohe Temperatur".Many of these applications only contain one of the two problems - either "high pressure" or "high temperature".
Bei Anwendungsfällen, bei denen die bekannten Stromdurchführvorrichtungen sowohl Temperaturen von mehreren 1000 K als auch Drücke von mehreren 1000 bar auszuhalten haben, treten bisher Probleme auf, da alle ausreichend druckfesten Stromdurchführvorrichtungen bei hohen Temperaturen ihre Festigkeit verlieren und dadurch unbrauchbar werden. Ausreichend temperaturfest ausgebildete Stromdurchführvorrichtungen wiederum können zwar den hohen Temperaturen standhalten, sind jedoch nicht ausreichend hochdruckbeständig.In applications in which the known current carrying devices have to withstand both temperatures of several 1000 K and pressures of several 1000 bar, so far occur problems because all sufficiently pressure-resistant Stromdurchführvorrichtungen lose their strength at high temperatures and thus unusable. Sufficiently temperature-resistant current carrying devices, in turn, can withstand the high temperatures, but are not sufficiently high pressure resistant.
Aufgabe der vorliegenden Erfindung ist es daher, eine Stromdurchführvorrichtung, die Drücke und Temperaturen bis zu mehreren 1000 bar und bis zu mehreren 1000 K standzuhalten vermag, anzugeben.The object of the present invention is therefore to provide a current feedthrough device capable of withstanding pressures and temperatures of up to several thousand bars and up to several thousand K.

Die erfindungsgemäße Stromdurchführvorrichtung besteht aus einem Flansch 1 , der eine durch ihn führende erste Stromdurchführung 5 aufweist. Diese ist für Temperaturen von wenigstens 400 K, vorzugsweise von wenigstens 3000 K, ausgelegt. Die erfindungsgemäße Stromdurchführvorrichtung weist ferner eine mit dem Flansch 1 verbundene Glocke 2 auf. In vorteilhafter weise sind Flansch 1 und Glocke 2 lösbar miteinander verbunden, vorzugsweise miteinander verschraubt 3.The current feedthrough device according to the invention consists of a flange 1, which has a first current feedthrough 5 leading through it. This is designed for temperatures of at least 400 K, preferably of at least 3000 K. The current feedthrough device according to the invention also has a with the Flange 1 connected bell 2 on. In an advantageous manner, flange 1 and bell 2 are releasably connected to one another, preferably screwed together. 3
An der dem Flansch 1 gegenüberliegenden Seite der Glocke 2 ist eine zweite Stromdurchführung 7 angeordnet, die für Drücke von wenigstens 500 bar, vorzugsweise von wenigstens 3000 bar, ausgelegt ist. Die beiden Stromdurchführungen 5 und 7 wiederum sind über eine Leitung 6 miteinander verbunden.On the side opposite the flange 1 side of the bell 2, a second current feedthrough 7 is arranged, which is designed for pressures of at least 500 bar, preferably of at least 3000 bar. The two current feedthroughs 5 and 7 are in turn connected to each other via a line 6.
Innerhalb der Glocke 2 ist ein druckübertragendes Medium 4 angeordnet. Bei diesem handelt es sich vorzugsweise um Wasser, ein synthetisches Öl, ein sog. Trafo-Öl oder ein Gemisch aus den vorgenannten Medien. Darüber hinaus können auch andere druckübertragende Medien und Gemische aus druckübertragenden Medien zur Anwendung kommen. Der Flansch 1 sowie die Glocke 2 sind abgedichtet, so dass das druckübertragende Medium 4 nicht entweichen kann.Within the bell 2, a pressure-transmitting medium 4 is arranged. This is preferably water, a synthetic oil, a so-called. Trafo oil or a mixture of the aforementioned media. In addition, other pressure-transmitting media and mixtures of pressure-transmitting media may be used. The flange 1 and the bell 2 are sealed, so that the pressure-transmitting medium 4 can not escape.
Die erfindungsgemäße Stromdurchführung ist jeweils so anzuordnen, dass die Unterbzw. Außenseite des Flansches 1 die hohe Temperatur "sieht". Der ebenfalls auf der Unter- bzw. Außenseite des Flansches 1 anliegende hohe Druck wird über den Flansch 1 sowie das druckübertragende Medium 4 an die Glocke 2 weitergegeben. Aus diesem Grund ist an der Oberseite der Glocke 2 bzw. auf der dem Flansch gegenüberliegenden Seite der Glocke 2 die zweite, für Drücke von wenigstens 500 bar ausgelegte Stromdurchführung 7 angeordnet.The current feedthrough according to the invention is in each case to be arranged so that the Unterbzw. Outside of the flange 1 "sees" the high temperature. The voltage also applied to the bottom or outside of the flange 1 high pressure is passed through the flange 1 and the pressure-transmitting medium 4 to the bell 2. For this reason, the second, designed for pressures of at least 500 bar current feedthrough 7 is arranged at the top of the bell 2 or on the opposite side of the bell 2.
Die in den Figuren 1 und 2 dargestellte Ausführungsform der erfindungsgemäßenThe embodiment of the invention shown in Figures 1 and 2
Stromdurchführvorrichtung weist ferner Mittel zur Einstellung des Vorspanndruckes des druckübertragendes Mediums 4 auf. Diese sind in Form einer Druckeinstell- bzw. Druckregeleinrichtung 8 ausgebildet, über die der gewünschte Vorspanndruck des druckübertragenden Mediums 4 erzeugt bzw. eingestellt werden. Damit wird eine Vorspannkraft auf den Flansch 1 bzw. die Stromdurchführung 5 aufgebracht.Stromdurchführvorrichtung further comprises means for adjusting the biasing pressure of the pressure-transmitting medium 4. These are in the form of a pressure adjustment or pressure control device 8, via which the desired pretensioning pressure of the pressure-transmitting medium 4 is generated or adjusted. Thus, a biasing force on the flange 1 and the current feedthrough 5 is applied.
Die Druckeinstell- bzw. Druckregeleinrichtung 8 kann des Weiteren so ausgebildet sein, dass sie auch als Einfüllvorrichtung für das druckübertragende Medium 4 dient. Die erfindungsgemäße Stromdurchführung ist vergleichsweise einfach aufgebaut und damit kostengünstig. Sie stellt in unterschiedlichen Anwendungsbereichen die einzige Möglichkeit dar, eine dauerfeste, temperatur- und druckbeständige Stromdurchführung zu schaffen.The pressure adjustment or pressure control device 8 may further be designed so that it also serves as a filling device for the pressure-transmitting medium 4. The current feedthrough according to the invention has a comparatively simple structure and is therefore cost-effective. It is the only way to create a durable, temperature and pressure resistant power feedthrough in different applications.
Die verwendeten Materialien der Stromdurchführvorrichtung werden durch den jeweiligen Anwendungsfall bestimmt. Der Flansch 1 und die Stromdurchführung 5 müssen selbstverständlich aus einem ausreichend temperaturbeständigen Material bestehen. Des Weiteren sind mögliche Eigenschaften desjenigen Mediums, mit dem der Flansch 1 und die Stromdurchführung 5 in Berührung kommen, zu berücksichtigen.The materials used in the current feedthrough device are determined by the particular application. The flange 1 and the current feedthrough 5 must of course consist of a sufficiently temperature-resistant material. Furthermore, possible properties of the medium with which the flange 1 and the current feedthrough 5 come into contact must be taken into account.
Die Glocke 2 sowie die Stromdurchführung 7 müssen aus einem ausreichend druckbeständigen Material mit hohen Festigkeitswerten bestehen. Ausschlaggebend für die Materialwahl ist dabei der auftretende Maximaldruck, der von Anwendungsfall zu Anwendungsfall variiert.The bell 2 and the current feedthrough 7 must be made of a sufficiently pressure-resistant material with high strength values. Decisive for the choice of material is the occurring maximum pressure, which varies from application to application.
