Description
Gleichrichter. Die Anmelderin hat- gefunden, dass im Gegensatz zu den Literaturangaben in einer Entladungsröhre die Durchschlagspannung de"; Gases nicht auf dem Stoff der Elektro- den, besonders der Kathode, unabhängig ist, sondern dass bei nicht- zu grossem Elektroden- abstand oder nicht zu grossem Gasdruck die Durehschlagspannung für ein bestimmtes Gas grösstenteils durch den Elektrodenstoff be stimmt wird.
Diese Eigenschaft hat die An- melderin zür Anfertigung eines Gleielirich- ters benutzt-. In der einfachsten Gestalt be steht er zum Beispiel_ aus einer mit einem so- genannten Edelgas, wie zum Beispiel Argon, gefüllten Entladungsröhre und zwei Elektro den von verschiedenem Stoff, wie zum Bei spiel Eisen und Magnesium. Die Durchschlag- spannung ist nun erheblich niedriger, wenn das Magnesium die Kathode bildet, als wenn die Eisenelektrode Kathode ist.
Bei zweck mässig gewählter Wechselspannung wird da her nur dann Strom durchgelassen, wenn das Ma-nesium die Kathode ist, so dass unbedingt tz Gleichrichtung eintritt. Die zugehörige Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungs- gegeiListandes. Sie zeigt einen GleichLrieUter mit Eleldroden aus ungleichartigen Stoffen, welcher in der Hauptsache durch eine kugel- förmigeGlasröhrel, eineKathode2 aus Mag nesium und eine Anode<B>3</B> aus Eisen gebildet wird.
Die Elektroden sind durch Stromein- führungsdrähie <B>6</B> und<B>7,</B> welche luftdicht in Glasstützen'8 und<B>9</B> eingeschmolzen sind, mit den Aussenleifungen verbunden. Um Zer- stäl--tbungen der Elektroden vo#zube-agen, wel che, die Wirkung des Gleichrichters ungün stig beeinflussen würde, ist zwischen den ElektrodIen ein Schirm 4 angeordnet, welcher mittelst Halterdrähte <B>5</B> befestigt ist. Dieser Schirm wird zweckmässig aus Glimmer oder Metall oder irgend einem andern geeigneten Material hergestellt.
Die Gasfüllung des Gleichrichters kann aus Argon oder einem andern Edelgase bestehen. Wechselströme werden, wenn die Spannung an der Entla- dungsröllre etwa<B>110</B> Volt beträgt, einseitig durchgelassen und demnach in pulsierenden Gleichstrom verwandelt,
Rectifier. The applicant has found that, in contrast to the literature in a discharge tube, the breakdown voltage de "; gas is not independent of the material of the electrodes, especially the cathode, but that if the electrode spacing is not too large or not too high gas pressure the breakdown voltage for a certain gas is largely determined by the electrode material.
The applicant has used this property for the production of a rectifier. In its simplest form it consists, for example, of a discharge tube filled with a so-called noble gas, such as argon, and two electrodes made of different materials, such as iron and magnesium. The breakdown voltage is now considerably lower when the magnesium forms the cathode than when the iron electrode is the cathode.
With an appropriately chosen alternating voltage, current is only allowed to pass if the magnesium is the cathode, so that rectification absolutely occurs. The accompanying drawing illustrates an exemplary embodiment of the subject matter of the invention. It shows an equalizer with elbow electrodes made of dissimilar materials, which is mainly formed by a spherical glass tube, a cathode 2 made of magnesium and an anode 3 made of iron.
The electrodes are connected to the external leads by current lead wires <B> 6 </B> and <B> 7 </B>, which are airtightly fused in glass supports 8 and 9. In order to prevent destruction of the electrodes, which would have an unfavorable effect on the effect of the rectifier, a screen 4 is arranged between the electrodes, which screen is fastened by means of holding wires 5. This screen is expediently made of mica or metal or any other suitable material.
The rectifier's gas filling can consist of argon or another noble gas. If the voltage at the discharge roller is about <B> 110 </B> volts, alternating currents are let through on one side and are therefore converted into pulsating direct current,
