Description
Schaltung zur selbsttätigen elektrischen Regelung der Temperatur in mehreren Räumen, insbesondere in Abteilen von Eisenbahnwagen, die wahlweise mit verschiedenen Heizmitteln (beispielsweise Dampf oder Elektrizität) geheizt werden Für die elektrische Temperaturregelung in den Abteilen von Eisenbahnwagen, die sowohl mit Dampf- als auch mit elektrischer Heizung ausgerüstet sind, ist eine Schaltung bekannt, bei der die Regelung der Heizmittelzufulir in jedes Abteil durch für jede Heizungsart besondere Schütze geschieht, die innerhalb eines Abteils durch ein Kontaktthermometer gesteuert werden. Die der gleichen Heizungsart zugeordneten Schütze aller Abteile liegen an einer gemeinsamen Speiseleitung. A15 Spannungsquelle dient eine .@kkttmulatorenl)atterie. Um einen unnötigen Energieverbrauch der Regeleinrichtung zu vermeiden, wird immer nur die Speiseleitung für diejenigen Schütze unter Spannung gesetzt,, die der gerade in Betrieb befindlichen Heizungsart zugeordnet sind. Die Steuerung zweier in verschiedenen Stromkreisen liegender Schütze durch ein Kontaktthermometer in jedem Abteil bedingt eine Leitungsverzweigung vor (oder hinter) jedem Kontaktthermometer.Circuit for automatic electrical control of the temperature in several rooms, especially in compartments of railroad cars, which optionally with various heating means (e.g. steam or electricity) For electrical temperature control in the compartments of railroad cars, both are equipped with steam as well as electrical heating is a circuit known in which the regulation of Heizmittelzufulir in each compartment by for each Type of heating special contactors happens within a compartment through a contact thermometer being controlled. The contactors of all compartments assigned to the same heating type are on a common feed line. A15 voltage source is used by a. @ Kkttmulatorenl) atterie. In order to avoid unnecessary energy consumption by the control device, always only energized the feeder for those contactors, those of the straight are assigned to the type of heating in operation. Controlling two in different Circuits of horizontal contactors are conditioned by a contact thermometer in each compartment a branch in front of (or behind) each contact thermometer.
Wie man sich an Hand des in der Zeichnung dargestellten Schaltbildes, aus dem die elektrischen Sperrventile 2o bis 27 zunächst wegzudenken sind, überzeugt, entstehen bei dieser Schaltung infolgedes Auftretens von unerwünschten Zweigströmen Schwierigkeiten, wie noch ausführlich' erläutert werden wird.How to use the circuit diagram shown in the drawing, from which the electric Stop valves 2o to 27 are initially imaginable are convinced, arise in this circuit as a result of the occurrence of undesirable Branch stream difficulties, as will be explained in detail later.
In der Zeichnung bedeuten i die Speiseleitung für die beispielsweise die Dampfheizung regelnden Schaltschütze 2, 3, 4, 5. 6 ist die Speiseleitung für die die elektrische Heizung regelnden Schaltschütze 7, 8, 9, 10. Die Kontaktthermometer i i, 12, 13, 14 befinden sich in den einzelnen Abteilen, und., die durch sie gesteuerten Schaltschützenpaare 7, 3, 8, 3 usw. regeln die Heizmittelzufuhr zu diesen Abteilen. Der Kontakt 15 verbindet die Speiseleitung 1 und der Kontakt 16 die Speiseleitung 6 mit dem positiven Pol A der im einzelnen nicht dargestellten Spannungsquelle. Die Kontaktthermometer i i bis 14 verbinden beim Ansprechen die Verzweigungspunkte B, C, D, E über die Leitung 17 mit dem negativen Pol F der Spannungsquelle und setzen dadurch diejenigen Schaltschütze in Tätigkeit, deren Speiseleitung mit dem Pol A verbunden ist.In the drawing, i mean the feed line for the contactors 2, 3, 4, 5, which regulate the steam heating, for example. 6 is the feed line for the contactors 7, 8, 9, 1 0 regulating the electrical heating. The contact thermometers ii, 12, 13, 14 are located in the individual compartments, and., The contactor pairs 7, 3, 8, 3, etc. controlled by them regulate the supply of heating medium to these compartments. The contact 15 connects the feed line 1 and the contact 16 connects the feed line 6 to the positive pole A of the voltage source, not shown in detail. When responding, the contact thermometers ii to 14 connect the branch points B, C, D, E via the line 17 to the negative pole F of the voltage source and thereby activate those contactors whose feed line is connected to the pole A.
Nimmt man nun an, daß gerade elektrisch geheizt wird, daß also der Kontakt 16 geschlossen ist, und nimmt man ferner an, daß alle Kontaktthermometer 11 bis 14 angesprochen haben, so fließen durch die Schaltschütze 7, 8, 9, io und die Kontaktthermometer 11, 12, 13, 14 Ströme. Öffnet jetzt beispielsweise das Kontaktthermometer i i seinen Stromkreis dadurch, daß seine Quecksilbersäule 18 außer Berührung kommt mit dem Kontakt i9, so wird dadurch jedoch das Schaltschütz 7 nicht, wie beabsichtigt, stromlos, sondern der Strom fließt jetzt durch das Schaltschütz 7 über den Verzweigungspunkt B, das Schaltschütz 2 und über die entsprechenden Abschnitte der spannungslosen Speiseleitung i durch die Schaltschütze 3, 4 und 5 und die Kontaktthermometer 12, 13, 14, die ja noch nicht geöffnet haben, zum negativen Pol F der Speisequelle. Dies hat zur Folge, daß das Schaltschütz 7 nicht - oder nicht mit Sicherheit - abfällt, da der hindurchfließende Strom nur wenig unter die Hälfte des Anspreehwertes des Schaltschützes absinkt. Auch wenn eines der übrigen Kontaktthermometer schon geöffnet hätte, würde das Schaltschütz des neu ansprechenden Kontakt thermometers noch mit den Strömen durch die Schaltschütze aller anderen belastet. Ein weiterer Nachteil dieser Schaltung wäre, daß die Kontaktc der Kontaktthermometer selbst zusätzlich durch diese Zweigströme belastet würden.If one now assumes that there is currently electrical heating, that is, the Contact 16 is closed, and it is also assumed that all contact thermometers 11 to 14 have responded, so flow through the contactors 7, 8, 9, io and the contact thermometers 11, 12, 13, 14 currents. For example, now open the contact thermometer i i his circuit in that his mercury column 18 comes out of contact with the contact i9, then the contactor 7 is not, as intended, de-energized, but the current now flows through the contactor 7 via the branching point B, the contactor 2 and over the corresponding sections of the dead Feed line i through the contactors 3, 4 and 5 and the contact thermometer 12, 13, 14, which have not yet opened, to the negative pole F of the supply source. This has the consequence that the contactor 7 does not - or not with certainty - will drop out, because the current flowing through it is only slightly below half of the response value of the Contactor drops. Even if one of the other contact thermometers is already open would have, the contactor of the new responsive contact thermometer would still with the currents through the contactors of everyone else. Another disadvantage this circuit would be that the Kontaktc the contact thermometer itself in addition would be burdened by these branch currents.
Zur Vermeidung dieses Übelstandes ist es schon bekanntgeworden, die Verzweigüngspunkte B, C, D, E in die Kontaktthermometer zu verlegen, und zwar so, daß man die' Zuleitungen zu den Schaltschützenpaaren getrennt an die Kontaktthermometer herangeführt und statt nur eines Kontaktdrahtes zwei Kontaktdrähte in die Kapillarröhren der Kontaktthermometer eingeschmolzen hat, die auf gleicher Höhe liegen und durch die Quecksilbersäule gleichzeitig geschlossen, aber auch gleichzeitig geöffnet und getrennt werden. Dies° Doppelkontaktthermometer haben den Nachteil, daß sich zwischen den beiden in geringem Abstand voneinander in die Kapillarröhre eingeschmolzenen Kontaktdrähten im Laufe der Zeit eine leitende Brücke bildet, da die Kontaktthermometer bekanntlich an den Offnungs- und Schließungsstellen allmählich verschmutzen, und da sich an der Glaswand Stoffe niederschlagen, die - zum Teil wenigstens - aus feinst verteiltem Quecksilber bestehen. Leicht kann auch der Fall eintreten, daß die Quecksilbersäule bei ihrem Absinken ein Quecksilbertröpfchen zwischen den beiden so dicht nebenexnanderliegenden Kontaktdrähten in der Kapillarröhre zurückläßt, so daß die Kontaktdrähte durch Kurzschluß miteinander verbunden sind. In beiden Fällen ist der durch die Verwendung von Doppelkontaktthermometern erstrebte. Zweck vereitelt.To avoid this inconvenience, it has already become known that To relocate branch points B, C, D, E in the contact thermometer, as follows, that the 'supply lines to the contactor pairs are separated to the contact thermometer and instead of just one contact wire, two contact wires into the capillary tubes the contact thermometer has melted, which are at the same height and through the mercury column closed at the same time, but also opened and at the same time be separated. This ° double contact thermometers have the disadvantage that between the two melted into the capillary tube at a small distance from each other Contact wires form a conductive bridge over time as the contact thermometer is known to gradually pollute at the opening and closing points, and because substances are deposited on the glass wall which - at least in part - are made of the finest distributed mercury. It can also easily happen that the mercury column as they sink a droplet of mercury between the two so close together Leaves contact wires in the capillary tube, so that the contact wires by short circuit are connected to each other. In both cases this is due to the use of double contact thermometers aspired. Purpose foiled.
Im Gegensatz zu der bekannten Maßnahme schlägt die Erfindung vor, die Stromverzweigung außerhalb der Kontaktthermometer zu belassen. also jeweils Kontaktthermometer mit nur einem Öffnungs- und Schließungskontakt zu verwenden und in die Stromkreise der Schaltschütze elektrische Sperrventile einzuschalten, die den Strom nur in derjenigen Richtung durchlassen, in der er im Betriebsfall der Schaltschütze beim Ansprechen der Kontaktthermometer fließt.In contrast to the known measure, the invention proposes to leave the power branch outside the contact thermometer. so each To use contact thermometers with only one opening and closing contact and to switch on electrical shut-off valves in the circuits of the contactors, the only let the current through in the direction in which it would run when the Contactors flow when the contact thermometer responds.
In dem Schaltbild der Zeichnung sind in die Kreise der einzelnen Schaltschütze Gleichrichter 20, 21, 22, 23, 24, 25, 26, 27 als elektrische Sperrventile eingeschaltet, die verhindern, daß in der erwähnten Weise unerwünschte Zweigströme durch die einzelnen Schaltschütze fließen. 28, 29, 30, 31 sind die bisher schon üblichen, den Kontaktthermometern parallel geschalteten Sperrventile (Gleichrichter), die zur Funkenlöschung dienen.In the circuit diagram of the drawing are the circles of the individual contactors Rectifiers 20, 21, 22, 23, 24, 25, 26, 27 switched on as electrical shut-off valves, which prevent undesired branch currents through the individual in the manner mentioned Contactors flow. 28, 29, 30, 31 are the usual contact thermometers shut-off valves (rectifiers) connected in parallel, which serve to quench sparks.
Die vorgeschlagene Schaltung ist auch anwendbar in denjenigen Fällen, in denen statt eines Kontaktthermometers mehrere bei verschiedenen Temperaturen ansprechende Kontaktthermometer umschaltbar parallel geschaltet sind. Hierbei ergibt sich noch gegenüber der Verwendung von Doppelkontaktthermometern der zusätzliche Vorteil, daß der jetzt anzuwendende Umschalter wesentlich einfacher gebaut sein kann, da die Kontaktthermometer nur einpolig umgeschaltet werden müssen.The proposed circuit can also be used in those cases in which instead of one contact thermometer several at different temperatures responsive contact thermometers are switchable in parallel. This results in there is also the additional benefit compared to the use of double contact thermometers Advantage that the switch to be used now be built much simpler can, as the contact thermometers only have to be switched single-pole.
