Description

Einrichtung zur Energieversorgung der Hilfseinrichtungen von Hochspannungsstromrichtern Bei der Energieversorgung der Hilfseinrichtungen von Hochspannungsstromrichtern, zu denen unter anderem die Kathodenheizung, die Erregung, die Vakuumpumpe und die Steuerung gehören, muß darauf Rücksicht genommen werden, daß sich diese Hilfseinrichtungen gegenüber Erde auf dem gleichen 'hohen Potential befinden wie dias betreffend,-, Stromrichtergefäß selbst. Es ist üblich, zur potentialmäßigen Trennung der Hilfseinirichtungen von der auf Erdpotential befinälichen Energiequelle Isoliertransformatoren zu verwenden. Obwohl die für die Speisung der Hilfseinrichtungen zu übertragende Leistung nur klein ist, sind- die Abm-,ssun---en solcher Isoliertransformatoren und! damit auch ihr Preis unverhältnismäßig groß, und, zwar deshalb, weil bei den hier in Betracht kommenden Spannungeen der Einfluß der Leistung gegenüber dem Einfluß, der durch die notwendige Isolation bedingt ist, nahezu verschwindet.Device for supplying energy to the auxiliary devices of high-voltage converters When supplying power to the auxiliary equipment of high-voltage converters, to which among other things the cathode heating, the excitation, the vacuum pump and the Control, it must be taken into account that these auxiliary equipment opposite earth are on the same high potential as concerning dias, -, Converter vessel itself. It is customary for the potential separation of the auxiliary devices to use isolating transformers from the energy source which is at ground potential. Although the power to be transmitted for supplying the auxiliary equipment is only is small, are the dimensions, ssun --- s of such isolating transformers and! so too their price disproportionately high, and that is because they are considered here coming tensions the influence of the achievement versus the influence that by the necessary isolation is conditional, almost disappears.

Der Erfindung liegt die Aufgabe zugrunde, die Energieversorgung der Hilfseinrichtungen von auf hohem Potential befindlichem Stromrichtergefäß ohne Benutzung von Isoliertransformatoren durchzuführen. Diesgeschieht gemäß der Erfindung dadurch, daß zur Energieübertragung ein strömendes, gasförmiges oder flüssiges isolierendes Medium verwendet wird. In erster Linie kommt hierbei Druckluft oder Drucköl in Betracht. Abgesehen von dem Wegfall der Isoliertransformatoren kann der Aufwand für die Durchführung der Erfindung auch aus dem Grunde sehr klein gehalten werden, weil es möglich ist, Idas zur Energieübertragung dienende gasförmige oder flüssige Med-ium gleichzeitig zu der ohnehin meist notwendigen Kühlung des Stromrichtergefäßes zu benutzen. Insbesondere eignet sich Drucköl sehr gut zur Kühlung der Kathode- des Stromrichtergefäßes.The invention is based on the task of supplying energy to the Auxiliary equipment from the converter vessel at high potential without being used to be carried out by isolating transformers. According to the invention, this is done by that for energy transfer a flowing, gaseous or liquid insulating Medium is used. Primarily compressed air or pressure oil come into consideration here. Apart from that the elimination of the isolating transformers can reduce the effort are kept very small for the implementation of the invention also for the reason, because it is possible to use Idas for energy transfer in gaseous or liquid form Med-ium at the same time as the cooling of the converter vessel, which is usually necessary anyway to use. In particular, pressure oil is very suitable for cooling the cathode of the converter vessel.

Diejenigen Hilfseinrichtungen, wie- z. B. die Vakuumpumpe, die eine mechanische Betätigung verlangen, können, durch entsprechende Aushildung oder durch Kupplung mit geeigneten Kraftmaschinen unmittelbar von dem zur Energieübertragung dienenden Medium angetrieben werden. Dagegen wird für die Hilfsbetriebe, die, wie z. B. die Kathodenheizting oder die Erregung, elektrische Energie benötigen, ein ebenfalls auf Hochspannungspotential befindlicher Generator vorgesehen, der von einer durch das strömende Medium gespeisten Kraftmaschine angetrieben wird. Dabei können, soweit dies mit Rücksicht auf die Eigenart der einzelnen Hilfsbetriebe zulässig ist, mehrere oder auch alle Hilfsbetriebe aus einem gemeinsamen Generator gespeist werden. Für die isolierte Zuführung der Druckflüssigkeit bzw. des Druckgases brauchen keine besonderen Zuleitungen vorgesehen zu werden, da es möglich ist, die hohlen Stützisolatüren, auf denen das Stromrichtergefäß einschließlich des Zubehörs aufgebaut ist, als ZufÜhrungsleitungen zu benutzen.Those auxiliary facilities such as B. the vacuum pump, the one require mechanical operation, through appropriate training or by Coupling with suitable prime movers directly from the one for power transmission serving medium are driven. On the other hand, for the auxiliaries that, like z. B. the Kathodenheizting or the excitation, need electrical energy, a also provided on high voltage potential generator, which is from a prime mover fed by the flowing medium is driven. Included can, insofar as this is permissible with regard to the individual nature of the individual auxiliary operations is fed to several or all of the auxiliaries from a common generator will. Need for the isolated supply of the pressure fluid or the pressure gas no special leads have to be provided as it is possible to use the hollow Support insulating doors on which the converter vessel including the accessories is built is to be used as supply lines.
