Description

Elektrischer Hochdruckdampferzeuger oder -dampfüberhitzer Die Erfindung betrifft einen elektrisch beheizten Hochdruckdampferzeuger oder -dampf= überhitzer, bei dem in für Flüssigkeits- oder Dampfdurchlauferhitzer bekannter Weise die Dampfrohre selbst als Heizwiderstände dienen und an eine mehrphasige Stromquelle so angeschlossen sind, daB; zwischen Ein- und Ausgang keine Spannung besteht.High pressure electric steam generator or superheater The invention relates to an electrically heated high-pressure steam generator or steam = superheater, in the manner known for liquid or steam flow heaters, the steam pipes themselves serve as heating resistors and are thus connected to a multi-phase power source are that; there is no voltage between input and output.

Gemäß der Erfindung ist ein hochdruckfestes, unverzweigtes Dampfrohr in verketteter Mehrphasenschaltung (Stern- oder Polygonschaltung) an die Stromquelle angeschlossen. Zu- und Ableitungsrohr können an das Durchlaufrohr an elektrischen Äquipotentialpunkten ohne isolierende Zwischenstücke angeschlossen werden. Durch die Vermeidung solcher Zwischenstücke, die bei hohen Drücken und Temperaturen schwer dicht zu halten sind, wird die Betriebssicherheit der Anlage wesentlich erhöht. Die Anordnung des Durchlaufrohres in einem einzigen unverzweigten Zug gestattet trotz der mehrphasigen Speisung eine mechanisch überaus einfache und widerstandsfähige Ausbildung des- Durchlaufrohres, das infolgedessen selbst bei den höchsten Drücken und Temperaturen vollkommen betriebssicher ausgeführt werden kann und in einfacher Weise den Anschluß an die Stromquelle in verketteter Mehrphas;enschaltung ermöglicht. Es erhält hierzu die Gestalt einer einfachen Rohrschlange, die mit einem Mindestmali von Verbindungsstellen an die Zu- und Ableitung angeschlossen und außerdem sehr einfach versteift werden kann.According to the invention is a high-pressure-resistant, unbranched steam pipe in chained multiphase circuit (star or polygon circuit) to the power source connected. Inlet and outlet pipe can be connected to the flow pipe on electrical Equipotential points can be connected without insulating spacers. By avoiding such spacers, which are difficult at high pressures and temperatures are to be kept tight, the operational safety of the system is significantly increased. The arrangement of the flow pipe in a single unbranched train is permitted despite the multi-phase supply, it is mechanically extremely simple and robust Formation of the flow tube, which as a result, even at the highest pressures and temperatures can be carried out completely reliably and in a simple manner Way enables the connection to the power source in a concatenated multi-phase circuit. For this purpose it is given the shape of a simple pipe snake, which with a minimum mali connected by connection points to the inlet and outlet and also very can easily be stiffened.

Die Zeichnung zeigt Ausführungsbeispiele der Erfindung. Fig. z gibt eine dreiphasige Sternschaltung, Fig. 2 eine Dreieckschaltung und Fig. 3 das Schema einer baulichen Anordnung des Durchlaufrohres wieder.The drawing shows exemplary embodiments of the invention. Fig. Z gives a three-phase star connection, Fig. 2 a delta connection and 3 shows the diagram of a structural arrangement of the flow pipe again.

Nach Fig. i bildet das Rohr b eine dreiphasige Doppelsternschaltung, in deren elektrischem Sternpunkt die Eintrittsstelle A tiiiCl die Austrittsstelle B liegen. An den Endeii der Sternarme sind bei C, B und F' die Phasenleitungen des Netzes j angeschlossen.According to Fig. I, the tube b forms a three-phase double star circuit, in its electrical star point the entry point A tiiiCl is the exit point B lie. At the end of the star arms are the phase lines of the at C, B and F ' Network j connected.

Nach rig. 2 liegen Ein- und Austr ittsstelle A und B an einem vorteilhaft zu erdenden Eckpunkt 3 des Schaltungspolygons C, D', F. After rig. 2, entry and exit points A and B are located at a corner point 3 of the circuit polygon C, D ', F.

Beiden Schaltungen ist gemeinsam, daß die an den einzelnen Abschnitten des Durchlatifrohres b auftretenden PI?asenspannungen sich auf dem Wege von der Eintrittsstelle A zur Austrittsstelle B zu Null ergänzen. Die anschließenden Leitungen /t und. i bleiben daher stromfrei und können ohne isolierende Zwischenstücke hochdrucksicher an das Rohr b angeschlossen «"erden.Both circuits have in common that those at the individual sections of the transit pipe b occurring pi? as tension on the way of the Add entry point A to exit point B to zero. The connecting lines / t and. i therefore remain current-free and can be protected against high pressure without insulating spacers connected to the pipe b «" earth.

Nach Fig.3 bildet das Dampfrohr eine einzige Rohrschlange, an der an geeigneten Stellen die Anschlüsse der verschiedenen Netzphasen angebracht sind. Die Schaltung entspricht hier beispielsweise der Dreieckschaltung nach Fig.2. Die Anordnung der Rohrwindungen in einem einzigen Zug hat u. a. auch den Vorteil, daß sich die Magnetfelder der drei Phasen bis auf die Streuung gegenseitig aufheben.According to Figure 3, the steam pipe forms a single coil on which the connections of the various mains phases are attached at suitable points. The circuit here corresponds, for example, to the delta circuit shown in FIG. the Arrangement of the pipe windings in a single train has, inter alia. also the advantage that the magnetic fields of the three phases cancel each other out except for the scattering.

Für große Leistungen können auch mehrere Rohrstränge parallel geschaltet werden. wobei zweckmäßig jeder davon nach Fig.3 ausgeführt wird.Several pipe strings can also be connected in parallel for high capacities will. each of which is expediently carried out according to FIG.
