Description
Von einphasigen, selbst nicht regelbaren. Heizvorrichtungen, die in einer Anzahl von Drei oder einem Vielfachen von Drei installiert sind und von einem symmetrischen Drehstromsystem gespeist werden, wird oft eine gesonderte Temperatur- und Leistungsregelung verlangt. Dies kann in bekannter Weise dadurch erreicht werden, daß man drei getrennte, temperaturgesteuerte zweipolige Schütze verwendet, die auf der Primärseite von drei getrennten, spannungsgeregelten Einphasentransformatoren zur Speisung der genannten Heizvorrichtungen mit je einem Schütz je Transformator eingeschaltet sind.From single-phase, even not controllable. Heating devices that come in a number of three or one Multiples of three are installed and fed by a symmetrical three-phase system, a separate temperature and power control is often required. This can be done in a known manner be achieved that one uses three separate, temperature-controlled two-pole contactors, the on the primary side of three separate, voltage-regulated single-phase transformers for supply of the heating devices mentioned are switched on with one contactor per transformer.
Nur für die gesonderte Regelung der Leistung von Hand oder selbsttätig und/oder für die gemeinsame Regelung der Leistung für die genannten Heizvorrichtungen können in ebenfalls bekannter Weise drei Einphasentransformatoren oder ein Dreiphasentransformator der Manteltype mit Lastschaltern oder Stufenschaltern zur Betätigung im Betrieb oder in spannungslosem Zustand ausgerüstet werden.Only for the separate regulation of the service manually or automatically and / or for the joint Regulation of the power for the heating devices mentioned can also be used in a known manner Way three single-phase transformers or one three-phase transformer of the jacket type with load switches or step switches for actuation during operation or in the de-energized state will.
Demgegenüber ist die Erfindung gekennzeichnet durch die Kombination eines Dreiphasen-Manteltransformatoa-s, dessen Primärwicklungen jeder Phase getrennt am Drehstromnetz angeschlossen sind, derart, daß eine äußere Dreieckschaltung entsteht und jede Primärwicklung mit einer Anzahl von Regelanzapfungen ausgeführt ist, die an gesondert von Hand betätigbare oder selbsttätig temperaturgesteuerte Last- oder Stufenschalter angeschlossen sind, und von. getrennten, in die beiden Zuleitungen von jeder Primärwicklung zum speisenden Sammelschienensystem eingeschalteten zweipoligen Schützen oder Schaltern, die von Hand betätigt oder von den Temperaturwächtern, in den getrennten an den Sekundärwicklungen des Transformators angeschlossenen Heizvorrichtungen gesteuert werden, die jede aus zwei an vier Klemmen geführten Hälften für Reihen- oder Parallelschaltung in jeder sekundären Wicklungsphase bestehen.. Die Eckpunkte der Dreieckschaltung sind, gewissermaßen in. das speisende Sammelschienensystem verlegt. Die Unterbrechungsorgane werden von Hand betätigt oder von Temperaturwächtern in den gesonderten, an den Sekundärwicklungen des Transformators angeschlossenen Heizvorrichtungen gesteuert, die jede aus zwei Hälften mit vier Klemmen für Reihen- oder Parallelschaltung in jeder sekundären Wicklungsphase bestehen.In contrast, the invention is characterized by the combination of a three-phase jacket transformer, whose primary windings of each phase are connected separately to the three-phase network, in such a way that that an outer delta connection is created and each primary winding with a number of control taps is carried out, the separately manually operated or automatically temperature-controlled Load switches or tap changers are connected, and from. separate, in the two leads from each Primary winding to the feeding busbar system switched on two-pole contactors or Switches that are operated manually or by the temperature monitors, in the separate heating devices connected to the secondary windings of the transformer can be controlled, each consisting of two halves led to four clamps for series or There are parallel connections in every secondary winding phase. The corner points of the delta connection are, so to speak, in. the feeding busbar system relocated. The interruption devices are operated manually or by temperature monitors in the controlled by separate heating devices connected to the secondary windings of the transformer, each consisting of two halves with four terminals for series or parallel connection in each secondary Winding phase exist.
Die Vorteile dieser Anordnung sind, daß nur ein Dreiphasentransformator benötigt ist an Stelle von drei Einphasentransformatoren für drei einphasig angeschlossene Heizvorrichtungen oder Öfen, insbesondere elektrische Blockwärmeöfen. Hierdurch werden große Ersparnisse im Preis, Gewicht und Platz AnordnungThe advantages of this arrangement are that only a three phase transformer is required instead of three single-phase transformers for three single-phase connected heating devices or ovens, in particular electric block heating furnaces. This results in great savings in price, weight and space arrangement

Die Erfindung ist im folgenden, an Hand der Zeichnung beschrieben, die in den Fig. 1, 2 und. 3 drei verschiedene Schaltarten der Heizvorrichtungen gemäß der Erfindung zeigt.The invention is described below with reference to the drawing described in Figs. 1, 2 and. 3 three different types of switching of the heating devices according to of the invention shows.
Der dreiphasige Manteltransformator ist in Fig. 1 generell mit 1 bezeichnet. Jede Primärwicklung 2 hat Anzapfungen 3 für getrennte Spannungsregelung jeder Phase. Die Primärwicklungen des Transformators sind, durch das speisende Sammelschienensystem 4 in Dreieck geschaltet. Die Spannungsregelung erfolgt mit Hilfe von gewöhnlichen Stufenschaltern, oder Lastschaltern 5, die getrennt von Hand oder automatisch in Abhängigkeit von. den Ofentemperaturen mit Hilfe von Thermoelementen 7 über Regler 9 betätigt werden. Diese Regelung ist durch den Umschalter 12 angedeutet. In den Zuleitungen zu den Primärwicklungen sind zweipolige Schütze 6 oder Schalter angeordnet, die von Hand betätigt oder von Thermoelementen 7 beeinflußt werden, die an den einzelnen Öfen 8 angeordnet sind. Mit 9 sind die Temperatur- und Leistungsregler bezeichnet. Um zwei Reihen Sekundärspannungen zu erhalten, die im Verhältnis 1 :2 stehen, werden die Sekundärwicklungen 10 des Transformators in an sich be-The three-phase jacket transformer is designated generally by 1 in FIG. 1. Each primary winding has 2 Taps 3 for separate voltage regulation of each phase. The primary windings of the transformer are connected in delta by the feeding busbar system 4. The voltage regulation takes place with the help of ordinary tap changers, or load switches 5, which are separated from Manually or automatically depending on. the oven temperatures with the help of thermocouples 7 can be operated via controller 9. This regulation is indicated by the switch 12. In the supply lines Two-pole contactors 6 or switches, which are operated by hand, are arranged for the primary windings or be influenced by thermocouples 7, which are arranged on the individual ovens 8. With 9 the temperature and power controllers are designated. To get two rows of secondary voltages, which have a ratio of 1: 2, the secondary windings 10 of the transformer are
