Description
Schaltungsanordnung zur selbsttätigen elektrischen Regelung der Heizung in Fahrzeugen, vorzugsweise Eisenbahnfahrzeugen In der Patentanmeldung H 18147 VIIIb/201 ist eine Schaltungsanordnung zur selbsttätigen elektrischen Regelung der Heizung in Fahrzeugen, vorzugsweise Eisenbahnfahrzeugen, mit mehreren mit Temperaturfühlern ausgerüsteten Abteilen oder Räumen beschrieben, bei der jeder Temperaturfühler durch sein Ansprechen bei Überschreitung der zulässigen Höchsttemperatur einen Hilfswiderstand überbrückt. Alle diese Hilfswiderstände sind miteinander in Reihe in einen Hilfsstromkreis geschaltet, dessen Strom, sobald eine festgesetzte Mindestzahl von Temperaturfühlern angesprochen hat, ein Relais zum Ansprechen bringt, das in an sich bekannter Weise ein Stellglied (Schaltschütz, Magnetventil od. dgl.) steuert, das die allen Abteilen oder Räumen zugeführte Heizenergie herabsetzt oder abschaltet. Die Anordnung ist im übrigen so getroffen, daß der Ansprechstrom für das Relais erst dann erreicht wird, wenn mehrere Temperaturfühler angesprochen und ihren Hilfswiderstand überbrückt haben, so daß die Herabsetzung der Heizleistung davon abhängig ist, ob in mehreren Abteilen die zulässige Temperatur überschritten ist oder nicht.Circuit arrangement for automatic electrical control of the heating in vehicles, preferably railway vehicles In patent application H 18147 VIIIb / 201 is a circuit arrangement for automatic electrical control of the heating in vehicles, preferably railway vehicles, with several with temperature sensors equipped compartments or rooms are described in which each temperature sensor through its response when the maximum permissible temperature is exceeded an auxiliary resistor bridged. All of these auxiliary resistors are connected in series with one another in an auxiliary circuit switched its current as soon as a set minimum number of temperature sensors has responded, brings a relay to respond in a manner known per se an actuator (contactor, solenoid valve or the like.) Controls the all compartments or rooms reduced or switched off heating energy. The arrangement is otherwise taken so that the response current for the relay only then reached is activated when several temperature sensors are addressed and their auxiliary resistance is bridged have, so that the reduction in heating power depends on whether in several Compartment the permissible temperature is exceeded or not.
Bei dieser Anordnung haben jedoch die Fahrgäste keinen Einfluß darauf, auf welchen Temperatursollwert die Heizung eingeregelt wird. Es ist aber meist sehr erwünscht, wenn auch den Reisenden eine gewisse Einflußnahme auf die Einstellung der Heizung - beispielsweise entsprechend ihrem bei Tag und bei Nacht unterschiedlichen Wärmebedürfnis - möglich ist. Um nun eine solche Einflußnahme bei der beschriebenen Anlage wiederum in der Art zu ermöglichen, daß eine Änderung der sich einstellenden Temperatur von dem Wunsch der Fahrgäste mehrerer Abteile abhängig ist, wird nach der Erfindung vorgeschlagen, in an sich bekannter Weise in jedem Abteil oder Raum mehrere bei verschieden hohen Temperaturen ansprechende Temperaturfühler vorzusehen, von denen wahlweise jeweils einer von Hand einschaltbar ist.With this arrangement, however, the passengers have no influence on The temperature setpoint to which the heating is regulated. But it is usually very desirable, even if travelers have some influence on attitudes the heating - for example, depending on how it differs by day and night Heat requirement - is possible. To now such an influence in the described Plant in turn in such a way as to enable a change in the setting Temperature depends on the wishes of the passengers of several compartments, is according to of the invention proposed in a manner known per se in each compartment or room to provide several temperature sensors that respond to different high temperatures, one of which can optionally be switched on manually.
An die Stelle einer der Zahl der einzustellenden Heizstufen entsprechenden Anzahl einzelner Temperaturfühler in jedem Abteil kann auch nur ein in an sich bekannter Weise auf verschiedene Ansprechtemperaturen umschaltbarer Temperaturfühler treten Die Zeichnung zeigt ein Ausführungsbeispiel der Schaltungsanordnung nach der Erfindung, bei der als umschaltbare Temperaturfühler Quecksilberkontaktthermometer dienen, die für drei Heizstufen ausgebildet sind.Instead of one corresponding to the number of heating levels to be set Number of individual temperature sensors in each compartment can only be one which is known per se Way to different response temperatures switchable temperature sensors step The drawing shows an embodiment of the circuit arrangement according to the invention, where mercury contact thermometers serve as switchable temperature sensors, which are designed for three heating levels.
W1, W2 ... W" sind die zu überbrückenden Hilfswiderstände der einzelnen Abteile, deren Reihenschaltung einen Zweig einer Brückenschaltung bildet, die sich im übrigen aus den Widerständen W", Wy und WZ zusammensetzt und an den Diagonalpunkten r1 und B gespeist wird. An die Diagonalpunkte C und D ist ein Relais R angeschlossen, das bei Überschreitung eines gewissen Brückenstromes anspricht und dadurch die Herabsetzung der Heizenergiezufuhr auslöst. T1, TZ . . . T" sind die Ouecksilberkontaktthermometer, von denen jedes drei Kontaktelektroden El, E2 und E3 aufweist, die in das Kapillarrohr in verschiedenen Höhen eingeschmolzen sind, so daß sie bei verschieden hohen Temperaturen von der Quecksilbersäule erreicht werden. Hl, H2 ... H" sind von Hand bedienbare Heizwahlschalter, mit denen wahlweise eine der Kontaktelektroden der einzelnen Kontaktthermometer eingeschaltet und somit die dieser Elektrode zugeordnete Ansprechtemperatur eingestellt werden kann. Jedoch regelt sich die Heizanlage, wie schon erwähnt, immer nur auf diejenige Temperatur ein, die an den Heizwahlschaltern mehrerer Abteile übereinstimmend eingestellt wurde.W1, W2 ... W "are to be bridged auxiliary resistances of the individual compartments, whose series circuit forms a branch of a bridge circuit, which in the rest of the resistors W" composed, Wy and WZ, and is fed to the diagonal points r1 and B. A relay R is connected to the diagonal points C and D , which responds when a certain bridge current is exceeded and thereby triggers the reduction of the heating energy supply. T1, TZ . . . T "are the mercury contact thermometers, each of which has three contact electrodes E1, E2 and E3, which are fused into the capillary tube at different heights so that the mercury column can reach them at different temperatures. Hl, H2 ... H" Manually operated heating selector switches with which one of the contact electrodes of the individual contact thermometers can be switched on and the response temperature assigned to this electrode can be set. However, as already mentioned, the heating system only ever adjusts to the temperature that has been set on the heating selector switches in several compartments.
