Description

Veränderlicher Luftkondensator mit unbeweglichen Plattensätzen und einem Stufenschalter Man hat bereits die mit Drehkondensatoren verbundenen Mängel dadurch zu beheben versucht, daß man ortsfeste Plattensysteme teilweise mit Drehplattensystemen untereinander serienweise ab- oder zuschaltet oder auch die eine Reihe der Platten stufenweise einschaltbar gestaltete, die Gegenplattenreihe dagegen in der üblichen Weise drehbar anordnete. Die erste Ausführungsform hat unter anderem den erheblichen Nachteil einer ungenauen Abstimmung, während bei der zweiten Anordnung der Nachteil hervorzuheben ist, daß nur eine Plattenreihe stufenweise ein- oder abschaltbar ist, die anderen Platten aber infolge ihrer leitenden Verbindung an der kapazitiven Änderung insofern unvorteilhaft mitwirken, als sie Anlaß zu Störungen und Kapazitätsverlusten geben.Variable air condenser with immobile plate sets and a tap changer One already has the shortcomings associated with variable capacitors Attempted to remedy that one fixed plate systems partially with rotating plate systems switches on or off in series with one another or also one row of the plates designed to be switched on step by step, the counter plate row, however, in the usual Way rotatably arranged. The first embodiment has, among other things, the substantial Disadvantage of inaccurate tuning, while the disadvantage of the second arrangement It should be emphasized that only one row of panels can be switched on or off in stages, the other plates, however, because of their conductive connection to the capacitive change to the extent that they contribute disadvantageously as they give rise to malfunctions and loss of capacity give.

Die Erfindung betrifft einen veränderten Luftkondensator mit unbeweglichen Plattensätzen und einem Stufenschalter, bei dem erfindungsgemäß die halbkreisförmig angeordneten Kontaktflächen des Schalters ein stufenweises .Zu- bzw. Abschalten sowohl der positiven als auch der negativen Kondensatorbelegungen gestatten. - Dadurch nehmen grundsätzlich nur die eingeschalteten Plattenpaare an der kapazitiven Änderung teil. Außerdem kann der ganze Kondensator auf einen denkbar kleinsten Raum beschränkt werden, was gerade mit Hinblick auf größere Empfangsapparaturen von Vorteil ist. Der auf der Zeichnung in einem Ausführungsbeispiel veranschaulichte Kondensator besteht aus vier aus zweckmäßig gewähltem Material hergestellten Isolierplatten a, b, c und d, die durch die metallenen Säulen e und f in bestimmten, durch die Anbringung der übrigen Apparateteile bedingten Abständen voneinander montiert sind. Zwischen den Isolierplatten b, und c sind die positiven und negativen Kondensatorplatten g isoliert gelagert. Zwischen den Isolierplatten c und d liegt die bewegliche Feineinstellung 1a, während der Stufenschalter i zwischen den Isolierplatten a und b angebracht ist. Die positiven und negativen Kondensatorplatten g sind mit den Kontaktstellen k des Stufenschalters galvanisch, L, so verbunden, daß durch Drehung der Skalenscheibe m die beiden isoliert voneinander montierten Kontaktfedern n und o bei gewünschter Kapazitätssteigerung nacheinander je eine positive und negative Kondensatorplatte g in den Stromkreislauf einschalten bzw. umgekehrt, wenn eine Verminderung der Kondensatorkapazität gewünscht wird, ausschalten. Die Differenz zwischen den sich auf diese Weise jeweils um je eine positive und negative Platte vergrößernden bzw. vermindernden Kapazitätsumfängen wird durch eine bewegliche, nicht über den Umfang des Kondensators hinausragende Feineinstellung überbrückt.The invention relates to a modified air condenser with immovable plate sets and a step switch, in which according to the invention the semicircular arranged contact surfaces of the switch allow the positive and negative capacitor assignments to be switched on and off in stages. - As a result, only the pairs of plates that are switched on take part in the capacitive change. In addition, the entire capacitor can be limited to the smallest possible space, which is particularly advantageous with regard to larger receiving equipment. The capacitor illustrated in an exemplary embodiment in the drawing consists of four insulating plates a, b, c and d made of appropriately selected material, which are mounted by the metal columns e and f at certain distances determined by the attachment of the other parts of the apparatus. The positive and negative capacitor plates g are insulated between the insulating plates b and c. The movable fine adjustment 1a is located between the insulating plates c and d, while the tap changer i is mounted between the insulating plates a and b. The positive and negative capacitor plates g are galvanically connected to the contact points k of the tap changer, L, in such a way that, by turning the dial m, the two insulated contact springs n and o each switch on a positive and negative capacitor plate g one after the other in the circuit if the capacity increase is desired or vice versa, if a reduction of the capacitor capacity is desired, switch it off. The difference between the capacitance scopes, each increasing or decreasing by one positive and one negative plate, is bridged by a movable fine adjustment that does not protrude beyond the scope of the capacitor.

Wirkungsweise des' veränderlichen Luftkondensators mit Stufenschaltung: Durch die positive Polklemme p tritt der elektrische Strom in die Metallsäule e ein. Von hier aus fließt er in die beiden festen Platten r und s der Feineinstellung sowie über eine dehnbare Stromleitung, beispielsweise eine Spiralfeder w, in die Kontaktfeder n, und von dort über die Kontaktstellen h in die jeweils eingeschalteten positiven Platten des Kondensators. Von der negativen Polklemme q tritt der elektrische Strom in die drehbare Feineinstellungsplatte t, durch die vom Skalenknopf 2c angetriebene Metallsäule v, und geht von dort über die Kontaktfeder o des Stufenschalters und die Kontaktstellen k in die jeweils eingeschalteten negativen Kondensatorplatten. Nunmehr wird die Abstimmung, d. h. die Erhöhung bzw. Verminderung des Kapazitätsumfanges des Kondensators durch Drehung der Skalenscheibe m des Stufenschalters und durch Drehung des Skalenknopfes u der Feineinstellung vorgenommen.How the variable air condenser works with step switching: The positive pole terminal p causes the electric current to enter the metal pillar e. From here it flows into the two fixed plates r and s of the fine adjustment and via an elastic power line, for example a spiral spring w, into the contact spring n, and from there via the contact points h into the respectively switched-on positive plates of the capacitor. From the negative pole terminal q, the electric current enters the rotatable fine adjustment plate t, through the metal column v driven by the dial 2c, and from there passes via the contact spring o of the tap changer and the contact points k into the respectively switched-on negative capacitor plates. The adjustment, ie the increase or decrease of the capacitance range of the capacitor, is now carried out by turning the dial m of the tap changer and by turning the dial u for fine adjustment.
