Description
Die Erfindung betrifft eine Ausbildung und Anordnung von Magneten für Vakuumapparate. Mit Hilfe dieser Magnete soll eine Einwirkung auf die Bewegung der Dampfstrecke im Innern des Apparates ausgeübt werden, beispielsweise um eine bestimmte Bahn des Lichtbogens zu erzwingen. Erfindungsgemäß wird der Magnet derart gestaltet und derart an der Wandung des Vakuumgefäßes befestigt, daß er nach dem Zusammenbau einen Teil des geschlossenen Gefäßes bildet. Dabei werden die Nachteile der bekannten Anordnungen vermieden, bei denen ein Teil des magnetischen Systems außen, der andere im Innern des Gefäßes liegt, und die Gefäßwand beide Teile voneinander trennt.The invention relates to a design and arrangement of magnets for vacuum apparatus. With the help of these magnets, an action is to be exerted on the movement of the steam path inside the apparatus be, for example, to force a certain path of the arc. According to the invention the magnet is designed and so attached to the wall of the vacuum vessel that after assembly forms part of the closed vessel. The disadvantages of the known Avoid arrangements in which one part of the magnetic system is outside, the other inside the vessel, and the The wall of the vessel separates the two parts.
In der Figur ist ein Beispiel der Erfindung gezeichnet, ι ist die Gefäßwand des Vakuumapparates, 2 ein Topfmagnet, dessen in-In the figure, an example of the invention is drawn, ι is the vessel wall of the vacuum apparatus, 2 a pot magnet whose internal
ao nerer Polkern 3 von der Magnetspule 4 umschlossen wird. Eine Platte S dichtet die Magnetspule gegen den Vakuumraum ab, 6 ist ein ringförmiges Gefäß mit der Quecksilberelektrode 7. Der Lichtbogen ist durch die punktierten Linien angedeutet und befindet sich im Magnetfelde, das von dem Pol 3 radial zu dem Ringpol 8 ausstrahlt. Bei dieser Anordnung findet eine ständige Drehung des Lichtbogens in der Rinne 6 statt. Die Gefäßwand ι wird zweckmäßig mit dem Magneten 2 an den Stellen 9 verschweißt oder verlötet. Die Zuführungen 10 zum Magneten können isoliert an irgendeiner Stelle des Topfes nach außen geführt werden. Luftdicht braucht diese Durchführung nicht zu sein, da die Platte 5 .den luftdichten Abschluß des Vakuum 6 herstellt. Auch diese Platte wird zweckmäßig mit dem Magneten 2 verschweißt oder verlötet. Bei dem gezeichneten Beispiel ist der Boden 11 des Topf magneten zusammen mit der Platte 5, der Spule 4 und dem Pol 3 von unten eingesetzt und mit dem Teil 2 irgendwie befestigt. Auch diese Verbindung braucht wegen des Abschlusses durch die Platte 5 nicht luftdicht zu sein. ao nerer pole core 3 is enclosed by the magnetic coil 4. A plate S seals the magnetic coil from the vacuum space, 6 is an annular vessel with the mercury electrode 7. The arc is indicated by the dotted lines and is located in the magnetic field that radiates from pole 3 radially to ring pole 8. With this arrangement there is a constant rotation of the arc in the channel 6. The vessel wall ι is expediently welded or soldered to the magnet 2 at the points 9. The feeds 10 to the magnet can be isolated to the outside at any point in the pot. This implementation does not need to be airtight, since the plate 5 creates the airtight seal for the vacuum 6. This plate is also expediently welded or soldered to the magnet 2. In the example shown, the bottom 11 of the pot magnet is inserted together with the plate 5, the coil 4 and the pole 3 from below and attached to the part 2 somehow. This connection also does not need to be airtight because of the closure by the plate 5.
