Bei den bisher bekannt gewordenen Quecksilberunterbrechern, von welchen u. A. auf den in der Elektrotechnischen Zeitschrift, Jahrgang 1898, Heft 40, beschriebenen hingewiesen werden möge, wird ein gegen einen Kupfercontact geschleuderter Quecksilberstrahl zur Herbeiführung des zeitweisen Stromschlusses benutzt. Bei allen diesen Unterbrechern ist die Stromschliefsung mehr oder weniger von dem Zufall abhängig, da dieselbe, selbst wenn eine gleichmäfsige Bewegung des Quecksilberstrahls vorausgesetzt wird, infolge der beim Gebrauch des Unterbrechers unvermeidlich eintretenden Verunreinigung des Quecksilbers nicht immer mit Sicherheit erfolgen kann.In the case of the mercury breakers that have become known so far, of which, among others, the in the Elektrotechnische Zeitschrift, year 1898, issue 40, as described a ray of mercury thrown against a copper contact is used to induce it the temporary power supply. With all of these breakers the current is closed more or less dependent on chance, since the same, even if there is a steady movement of the mercury beam is assumed as a result of the inevitable occurring when using the breaker Contamination of the mercury cannot always occur with certainty.

Nach vorliegender Erfindung soll das Quecksilber nicht als stromschliefsendes Mittel, sondern nur für die Amalgamirung zweier Kupferflächen benutzt werden, die zur Stromschliefsung dienen, und von welchen die eine sich in stetiger Umdrehung befindet. Die dauernd amalgamirten Kupferflächen, welche hierbei stets mit neuen Quecksilbermengen in Berührung kommen, sichern eine durchaus gleichmäfsige Stromschliefsung, die in nachstehend näher beschriebener Weise periodisch unterbrochen wird.According to the present invention, the mercury should not be used as a current-closing agent, but rather can only be used for the amalgamation of two copper surfaces, which are used to close the current serve, and one of which is in constant rotation. That all the time amalgamated copper surfaces, which are always in contact with new quantities of mercury come, ensure an even power supply, which is described in the following is periodically interrupted as described in more detail.

In beiliegender Zeichnung zeigt:The attached drawing shows:

Fig. ι einen senkrechten Schnitt des vorliegenden Unterbrechers;Fig. Ι a vertical section of the present Breaker;

Fig. 2 einen Schnitt A-B von Fig. 1.FIG. 2 shows a section AB from FIG. 1.

Der Unterbrecher ist in einem aus Isolirmaterial hergestellten Gefäfse 1 untergebracht, welches durch einen Deckel 2 abgeschlossen wird. Letzterer trägt ein Lager 3, durch welches eine am oberen Ende mit einer Schnurscheibe 4 versehene Achse 5 hindurchgeführt ist. Am unteren Ende der Achse 5 ist ein hohler Körper 6 aus Hartgummi oder dergl. befestigt, der nach unten durch einen Kupfermantel 7 abgeschlossen wird, welcher am Boden mit einigen excentrisch angeordneten Bohrungen 8 versehen ist. Der cylindrische Theil des Kupfermantels 7 besitzt den aus Fig. 2 ersichtlichen Querschnitt, bei welchem zwei einander gegenüber liegende -Viertel herausgeschnitten sind, so dafs nur zwei dazwischen liegende Manteltheile 9 und 10 erhalten bleiben. Jeder dieser Theile 9 und 10 des Kupfermantels 7 ist mit einem bis in den Inn erträum des Gummikörpers 6 hineinreichenden, wagerechten Einschnitte 11 bezw. 12 versehen.The interrupter is housed in a vessel 1 made of insulating material, which is closed by a cover 2. The latter carries a bearing 3 through which a shaft 5 provided with a cord pulley 4 at the upper end is passed through. At the lower end of the axis 5 is a hollow body 6 made of hard rubber or the like. Attached, which is down through a copper jacket 7 is completed, which on the ground with some eccentrically arranged holes 8 is provided. The cylindrical part of the copper jacket 7 has that shown in FIG Cross-section in which two opposite quarters are cut out are, so that only two intermediate shell parts 9 and 10 remain. Each of these parts 9 and 10 of the copper jacket 7 is dreamy with one up to the inside of the rubber body 6 reaching in, horizontal incisions 11 respectively. 12 provided.

Seitlich von dem als Centrifuge wirkenden. Körper 6 ist die aus Kupfer hergestellte, den Stromschlufs vermittelnde Stange 13 angebracht, an deren unterem Ende sich das Stromschlufsstück 14 befindet, welches gegen den cylindrischen Theil des Kupfermantels η· anliegt. Die dichte Auflage dieses Stromschlufsstückes 14 wird dadurch gesichert, dafs die'Stange 13, welche in dem Lagerstücke 1 5 auf dem Zapfen 16 drehbar ist, unter der Einwirkung einer Zugfeder 17 steht, welche bestrebt ist, den unteren Theil der Stange 13 gegen den Körper 6 bezw. den Kupfermantel 7 zu drücken. Damit das Stromschlufsstück 14 bei der Umdrehung des Körpers 6 nicht in die Ausschnitte zwischen den vollen Theilen 9 und 10 des Kupfermantels 7 eintreten kann, ist oberhalb des Stückes 14 eine aus Isolirmaterial hergestellteTo the side of the one that acts as a centrifuge. Body 6 is made of copper, the Stromschlufs mediating bar 13 attached, the Stromschlufsstück located at the lower end 14, which η against the cylindrical part of the copper cladding · applied. The tight support of this power connection piece 14 is ensured by the fact that the rod 13, which is rotatable in the bearing piece 15 on the pin 16, is under the action of a tension spring 17 which tries to hold the lower part of the rod 13 against the body 6 resp. to press the copper jacket 7. So that the Stromschlufsstück 14 cannot enter the cutouts between the full parts 9 and 10 of the copper jacket 7 during the rotation of the body 6, an insulating material is made above the piece 14

Claims

Plate 18 attached, which their permanent support has 6 on the cylindrical part 22 of the rubber body.

A copper bracket 19, which passes through the vessel 1, is located below the centrifuge is and with its outer end 20 mediates the power supply line, while the current of the rod 13 through the on the bearing pieces 15 seated line piece 21 supplied will. The interior of the vessel 1 is approximately up to that indicated in the drawing Height filled with mercury, above which there is a layer of alcohol.

If the body 6 and the copper jacket 7 connected to it is replaced by a suitable If the drive is set in rapid rotation, the electrical circuit is released with every rotation 14 once with the shell part 9 and once with the shell part 10 in contact, while the cutouts in between cancel the electric circuit and thus the Interrupt power. The quick rotation of the centrifuge removes the mercury sucked through the bores 8, conveyed upwards and through the thin incisions 11 and 12 thrown outwards, being partly held by the electrical connection piece 14 and is taken along by the jacket parts 9 and ι ο sliding over it and thus creates an intimate contact between the copper surfaces lying opposite one another. That not taken or Trapped mercury falls to the ground and collects again in the vessel 1.

In the present circuit breaker, the one raised by the centrifuge is thus lifted Mercury is used to amalgamate the conductive surfaces and thereby the To perfect electrical circuit formation, as well as the sliding friction between the electrically conductive Reduce areas. In this way, the current is closed even with the supply of strong currents even at the fastest Revolution of the interrupter reached with certainty.

Since experience shows that when the centrifuge is rotated within the vessel 1 in the The surface of the mercury forms a funnel, the depth of which changes with the speed of rotation As the centrifuge increases, there is an obvious danger that the power cut-off will not take place Safety takes place when the mercury is below the centrifuge as a result of the funnel formation sinks. In order to exclude this possibility and at the same time the otherwise the course The centrifuge according to the present invention is to prevent disturbing funnel formation as far as possible eccentrically arranged in the vessel of the interrupter, as can be seen from the drawing is. In this way, without special precautions, it is achieved that the centrifuge also causes only a slight movement of the mercury at its fastest revolution.
