Elektrisch beheizter Durchlauferhitzer für DrehstromanschlußElectrically heated water heater for three-phase connection

Die Erfindung betrifft einen elektrisch beheizten Durchlauferhitzer für Drehstromanschluß, und zwar einen solchen, bei dem in hintereinandergeschalteten Heizkanälen unmittelbar vom Wasser umspülte Heizwendeln angeordnet und den Heizkanälen einen elektrischen Wasae: säulenwiderstand bildende Widerstandskanäle vor- und nachgeschaltot sind.The invention relates to an electrically heated water heater for three-phase connection, namely one in which in series-connected Heating ducts arranged directly from the water bathed heating coils and the heating ducts an electric Wasae: Resistance channels forming column resistance upstream and downstream are.

Es ist bei solchen Geräten üblich, für jede Drehstromphase -ein Heiz· , wendelpaar in Reihenschaltung vorzusehen und die Heizwendelpaare einseitig zu einem Sternpunkt zu verbinden. Dabei ergeben sich jedoch gewisse Schwierigkeiten insofern, als bei hintereinandergeschalteten Heizkanälen der, Sternpunkt durch einen kurzen Wasserverbindungskanal mit einem Phasenanschlußpunkt in Verbindung kommt'. Zwischen Phase und Null (Sternpunkt) liegt also nur ein kurzer Wasserweg, so daß elektrolytische Erscheinungen auftreten können, die zur allmählichen Zerstörung der Anschlußklemmen führen. Wollte man den Wasserweg der Terbindungskanäle durch Vergrößerung der Heizkanalabstände verlängern, um einen größeren' elektrischen Widerstand zwischen den Heizkanälen zu erhalten, so würde das zu einer erheblichen Vergrößerung des Gerätes und des Durchflußwiderstandes führen.It is customary in such devices to provide a heating coil pair in series for each three-phase phase and to connect the heating coil pairs to a star point on one side. In this case, however, certain difficulties arise insofar as, in the case of heating ducts connected in series, the 'star point is connected to a phase connection point through a short water connection duct'. There is only a short water path between phase and zero (star point), so that electrolytic phenomena can occur, which lead to the gradual destruction of the connection terminals. If one wanted to rbindungskanäle the waterway T e by increasing the Heizkanalabstände extend to a larger 'electrical resistance between the heating channels to obtain, this would lead to a considerable enlargement of the device and the flow resistance.

Diese Schwierigkeiten werden erfindungsgemäß dadurch behoben, daß · für jede Drehstromphase (R.S.T.) zwei in benachbarten Heizkanälen angeordnete, zueinander parallelgeschaltete Heizwendeln vorgesehen und die sechs Heizwendelenden zum Sternpunkt (o) zusammen-According to the invention, these difficulties are eliminated by the fact that for each three-phase phase (R.S.T.) two heating coils arranged in adjacent heating channels and connected in parallel are provided and the six heating coil ends together to form the star point (o)

gesohaltet sind und daß die Heizkanäle, deren Heizwendeln_an_ver- are kept and that the heating channels, whose heating coils_an_ver-

schiedenen Phasen liegen, im Bereich des Sternpunktes (o) miteinander verbunden sind. Durch eine elektrische Parallelschaltung der beiden an einer Phase liegenden Heizwendeln ist es möglich, die wasserseitige Hintereinandersphaltung der Heizkanäle so vor- different phases are connected to each other in the area of the star point (o). By electrically connecting the two heating coils on one phase in parallel, it is possible to arrange the heating channels one behind the other on the water side.

zunehmen, daß durch die Ve^bindungskanäle keine Potentialdifferenz · überbrückt wird. Man kann daher den Abstand der Heizkanäle sehr gering machen und auf diese Weise zu einem Kanalkörper von kleinen Abmessungen gelangen.increase so that there is no potential difference through the connecting channels is bridged. You can therefore make the distance between the heating channels very small and in this way a channel body of small Dimensions arrive.

In bekannter Weise können die Hgizkanäle in einem Isolierstoffblock untergebracht werden. Dabei ist es zweckmäßig, die Anordnung so zu treffen, daß die Heizkanäle in zwei zueinander parallelen Ebenen hintereinanderliegen und einerseits paarweise miteinander durch senkrecht zu den Ebenen verlaufende Kanäle und andererseits die Heizkanalpaare im Bereich des Sternpunktes (o) durch parallel zu den Ebenen liegende Kanäle verbunden sind. Dabei kann der Abstand der Heizkanäle so klein sein, wie es der für die Überschlagsicherheit erforderliche Mindestabstand der Anschlußklemmen zuläßt.In a known manner, the Hgiz channels can be accommodated in a block of insulating material. It is expedient to make the arrangement such that the heating channels lie behind one another in two mutually parallel planes, and on the one hand one another in pairs to the planes extending channels and on the other hand Heizkanalpaare in B e reaching the star point (O) located by vertically through parallel to the planes Channels are connected. D a at the distance of the heating channels can be as small as permitted by the space required for the rollover safety minimum distance of the terminals.

Mit 1 ist der Kaltwassereinlaß bezeichnet, an den sich ein Widerstandskanal 2 anschließt, der relativ lang und eng ist und infolgedessen einen erheblichen elektrischen Wassersäulenwiderstand bildet.

Die Heiz·- wendeln sind paarweise elektrisch parallelgeschaltet und die sechs Enden der Heizwendelpaare 7, 7', 7" sind miteinander zu einem Sternpunkt ο verbunden. Das Heizwendelpaar 7 ist in den benachbarten Heizkanälen 4, 4' untergebracht, die durch einen Verbindun£3-kanal 4" im Bereich des Phasenanschlusses R miteinander in Verbindung stehen. In gleicher Weise sind die Heizwendelpaare 7'? 7" in den Heizkanalpaaren 5? 5' bzw. 6, 6' untergebracht und an die1 with the cold water inlet is referred to, to which a resistance channel 2 connects, which is relatively long and narrow and as a result forms a significant electrical water column resistance. The resistor channel 2 opens out into a system of series-connected heating channels 4> 4 1> 5> 5 '"6>6'" to ^ as a "outlet-resistance channel 3 is connected. For each three-phase current phase RS, T.

Die Heizkanäle 4' und 5 bzw. 5' und 6 sind durch Kanäle 8 bzw. 9 miteinander verbunden, die im Bereich des Sternpunktes ο -■liegen, so daß-sie keine Potentialdifferenz überbrücken. Bei dieser Anordnung liegt sowohl zwischen den Potentialen der Phasenanschlüsse E.S.T. und dem Sternpunkt ο als auch zwischen den einzelnen Phasenanschlüs^en R.S.T. selbst ein langer widerstandsbildender Wasserweg, obwohl die Verbindungskanäle 4M> 5"» 6", 8 und 9 äes Heizkanalsystems sehr kurz sind.
