Elektrisch geheizte Wärmespeicher werden in der Regel mit einem von einer Uhr gesteuerten Sperrschalter versehen, der die Benutzung des Speichers nur zu bestimmten Zeiten gestattet. Bisher hat man hierzu selbständige Schaltvorrichtungen verwendet. Nach der Erfindung wird eine wesentliche Vereinfachung erreicht, indem man den ohnehin zum Schutz des Heizkörpers erforderlichenElectrically heated heat accumulators are usually controlled by a clock Provide a lock switch that only allows the memory to be used at certain times. So far you have this independent switching devices used. According to the invention, an essential one Simplification is achieved by removing what is already required to protect the radiator
ίο selbsttätigen Ausschalter gleichzeitig als Sperrschalter benutzt. Dieser Ausschalter wird meist von einem Kontaktthermometer bedient, das bei Überschreitung einer bestimmten Temperatur die parallel zum Heizkörper liegende Wicklung eines Ausschaltrelais für den Heizstrom kurzschließt. Es ist also nur nötig, ' einen von der Uhr gesteuerten einfachen Schalter parallel zu dem Thermometer zu schalten, der bei Beginn der Sperrzeit die Relaiswicklung kurzschließt und bei Beendigung der Sperrzeit den Kurzschluß wieder aufhebt.ίο automatic off switch at the same time as locking switch used. This off switch is usually operated by a contact thermometer, which when a certain temperature is exceeded the winding of a switch-off relay for the heating current, which is parallel to the radiator shorts. It is therefore only necessary to switch a simple switch controlled by the clock in parallel to the thermometer switch, which short-circuits the relay winding at the beginning of the blocking time and when it ends the blocking time removes the short circuit again.
Damit wird nicht nur ein besonderer Sperrschalter, der für den gesamten Heizstrom bemessen sein müßte, gespeist, sondern gleichzeitig auch die Verwendung einer einfachen Schaltuhr ermöglicht, da deren Schalter nur für den gleichen sehr geringen Strom bemessen zu sein braucht wie das Kontaktthermometer. This not only creates a special lock switch that is designed for the entire heating current would have to be fed, but at the same time also enables the use of a simple timer, since its switch only needs to be rated for the same very low current as the contact thermometer.
In der Zeichnung ist eine Ausführungsform wiedergegeben.An embodiment is shown in the drawing.
In der Zuleitung zu dem Heizkörper β liegt ein Temperaturschalter, nämlich ein Relais a mit Quecksilberkippröhre b, welches in Kurzschlußschaltung durch ein Kontaktthermometer c bedient wird. Während nun sonst die Schaltuhr für den Sperrschalter bei A in die Hauptleitung eingeschaltet wurde, also einen Schalter für den vollen Strom des Heizkörpers e des Wärmespeichers benötigte, wird nach der Erfindung die Schaltuhr f parallel zum Thermometer c angeschlossen.In the supply line to the heating element β there is a temperature switch, namely a relay a with a mercury tilting tube b, which is operated in a short-circuit circuit by a contact thermometer c. While the timer for the locking switch at A was otherwise switched on in the main line, i.e. a switch was required for the full current of the heating element e of the heat accumulator, according to the invention the timer f is connected in parallel with the thermometer c .
Soll der Strom unterbrochen werden, so schließt die Uhr f den Schalter h. Letzterer bildet einen Kurzschluß zur Wicklung des Relais a, wodurch die Kippröhre b herunterfällt und der Strom unterbrochen wird. Beim öffnen des Schalters^ durch die Uhr f zieht der Magnet g die Kippröhre δ wieder an, und der Strom ist eingeschaltet.If the current is to be interrupted, the clock f closes switch h. The latter forms a short circuit to the winding of the relay a, whereby the tilt tube b falls down and the current is interrupted. When the switch ^ is opened by the clock f, the magnet g attracts the tilting tube δ again, and the current is switched on.
Die Wirkungsweise des Kontaktthermometers c wird dadurch nicht beeinträchtigt.This does not affect the functionality of the contact thermometer c.
Die Spulen des Relais α sind gewöhnlich für 10 Volt und 0,05 Ampere gewickelt, so daß der Schalter h den Nebenschluß zu einer Spule mit nur 0,5 Watt Stromverbrauch' bildet, also die kleinsten Dimensionen erhalten kann.The coils of the relay α are usually wound for 10 volts and 0.05 amperes, so that the switch h is shunted to a coil with only 0.5 watt power consumption ', that is to say can have the smallest dimensions.
