Description
<Desc/Clms Page number 1>
Anordnung zum Betrieb von gas-oder dampfgefüllten Entladungsgefässen mit Glüh- kathode
Es ist schon vorgeschlagen worden, die Heiz- spannung für eine Glühkathoden-Gleichrichter- röhre einer Hilfswicklung des Gleichrichtertransformators zu entnehmen, deren Spannung auf Grund der Zunahme des Transformatorstreuflusses mit zunehmender Belastung des
Gleichrichters in einem gewissen Ausmass abnimmt, wodurch der ansteigenden zusätzlichen Aufheizung, welche die Kathode durch den Entladungsstrom erfährt, Rechnung getragen werden soll.
Die Erfindung ermöglicht es, bei einer solchen Anordnung jedes gewünschte Ausmass der Lastabhängigkeit des Heizstromes sowohl bei Strom- richtertransformatoren mit starker, insbesondere künstlich erhöhter Streuung als auch bei solchen mit niedriger bzw. normaler Streuung zu erzielen, und zwar dadurch, dass die Hilfswicklung aus zwei Teilen besteht, deren Summen-oder Differenzspannung dem Heizkreis zugeführt wird und die an solchen verschiedenen Stellen des Transformators angebracht sind, dass sich die in ihnen induzierten Spannungen mit zunehmender Transformatorbelastung, also zunehmendem Streufluss in verschiedenem Masse ändern.
Die Teile der Hilfswicklung können insbesondere so angeordnet werden, dass der eine davon mit demselben Fluss wie die Primärwicklung oder mit demselben Fluss wie die Sekundärwicklung oder mit dem Streufluss und der andere mit einem anderen dieser drei Flüsse verkettet ist.

Arrangement for the operation of gas or vapor-filled discharge vessels with a hot cathode
It has already been proposed to take the heating voltage for a hot cathode rectifier tube from an auxiliary winding of the rectifier transformer, the voltage of which, due to the increase in the transformer leakage flux, increases with the load on the
Rectifier decreases to a certain extent, whereby the increasing additional heating, which the cathode experiences due to the discharge current, should be taken into account.
With such an arrangement, the invention makes it possible to achieve any desired extent of the load dependency of the heating current both in converter transformers with strong, in particular artificially increased, scatter and those with low or normal scatter, namely by having the auxiliary winding from two There are parts whose total or differential voltage is fed to the heating circuit and which are attached to such different points on the transformer that the voltages induced in them change to different degrees with increasing transformer load, i.e. increasing leakage flux.
The parts of the auxiliary winding can in particular be arranged in such a way that one of them is linked with the same flux as the primary winding or with the same flux as the secondary winding or with the leakage flux and the other with another of these three fluxes.
