  Aufladesteuerung für elektrische Speicherheizungen 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 Restwärme erfasst.   Mit-4-ist   ein mit einem   Fühler --6-- verbundener   Temperaturbegrenzer bezeichnet, der die Temperatur der Speicherheizung auf den höchst zulässigen Wert begrenzt. 



   Die dargestellte Aufladesteuerung funktioniert wie folgt : Befindet sich die Speicherheizung zu Beginn einer Aufladeperiode in voll aufgeladenem Zustand,   d. h.   es wurde seit der letzten Aufladeperiode der Speicherheizung fast keine Wärme entnommen, so sind zu diesem Zeitpunkt sämtliche Kontakte-a, b, c und 4', 4",   4"'--des   Thermostaten bzw. die   Temperaturregeleinrichtung --3-- und   des   Temperaturbegrenzers --4-- geöffnet   und die Speicherheizung bleibt bis zum Zeitpunkt der Unterschreitung eines bestimmten Temperaturwertes vom Netz getrennt.

   Ist zu Beginn einer Aufladeperiode ein bestimmter Temperaturwert unterschritten, so sind alle Kontakte--4', 4", 4"'--des Temperaturbegrenzers--4-und der Kontakt-c-des Thermostaten bzw. der Temperaturregeleinrichtung --3-- geschlossen, und es wird, wie in der Zeichnung dargestellt, die   Heizkörperanordnung--II--mit   der geringeren Heizleistung gespeist. Ist zu Beginn einer Aufladeperiode in der Speicherheizung ein bestimmter etwas tiefer gelegener Temperaturwert unterschritten, so sind die Kontakte-b und c-des Thermostaten bzw. der 
 EMI2.1 
 --3-- geschlossen. Wird--II- vom Netz abtrennt und die Heizkörperanordnung --I-- mit der grösseren Heizleistung an das Netz anschliesst.

   Ist zu Beginn einer Aufladeperiode ein bestimmter noch tiefer gelegener Temperaturwert unterschritten, so sind die   Kontakte--a, b und c--des Thermostaten--3--   geschlossen und es spricht sowohl der Leistungsschalter--l-als auch der Leistungsschalter--2an, wodurch beide   Heizkörperanordnungen-I   und   II-an   das Netz angeschlossen werden. Um eine kontinuierliche Aufladung der Speicherheizung trotz des während der Aufladeperiode stattfindenden öffnens der   Kontakte-a und b-sicherzustellen,   sind die Leistungsschalter --1 und 2-mit 
 EMI2.2 
    2'-versehen.2--abfallen lässt,   so dass nur die schwächere   Heizkörperanordnung--II--an   das Netz angeschlossen ist.

   Wird trotz dieser Reduzierung der Heizleistung die höchst zulässige Temperatur erreicht, so trennt der Temperaturbegrenzer auch die   Heizkörperanordnung--II--vom   Netz ab. 



   Die die Antriebe der Leistungsschalter steuernden Kontakte-a, b,   c-können   auch einzelnen Thermostaten angehören, deren Temperaturansprechwerte gestaffelt sind. Diese Kontakte müssen also nicht von einem einzigen Antrieb betätigt werden. 



   PATENTANSPRÜCHE : 
1. Aufladesteuerung für elektrische Speicherheizungen, bei der wenigstens zwei je eine Heizkörperanordnung enthaltende Teillastschaltungen vorgesehen sind, in die jeweils ein durch eine Temperaturregeleinrichtung in Abhängigkeit von der Temperatur der Speicherheizung automatisch betätigter Leistungsschalter bzw. ein Schütz eingesetzt ist, wobei die Temperaturansprechwerte der die einzelnen Leistungsschalter betätigenden Schaltvorrichtungen der Temperaturregeleinrichtung gestaffelt 
 EMI2.3 
 zwei Teillastschaltungen (I, II) mit unterschiedlich hohen Heizleistungen als Umschalter ausgebildet ist, an den ein in die Leitungsanordnung (7) zwischen Leistungsschalter (2', 2", 2"') und Heizkörperanordnung der andern Teillastschaltung (II) mündender Leitungszweig (8) angeschlossen ist.

  Charge control for electric storage heaters
 EMI1.1
 

 <Desc / Clms Page number 2>

 Residual heat recorded. A temperature limiter connected to a sensor --6-- is designated with -4-, which limits the temperature of the storage heater to the highest permissible value.



   The charging control shown works as follows: If the storage heater is in a fully charged state at the beginning of a charging period, i. H. Almost no heat has been extracted from the storage heater since the last charging period, so at this point in time all contacts-a, b, c and 4 ', 4 ", 4"' - of the thermostat or the temperature control device --3-- and of the temperature limiter --4-- is open and the storage heater remains disconnected from the network until the temperature falls below a certain value.

   If the temperature falls below a certain value at the beginning of a charging period, all contacts - 4 ', 4 ", 4"' - of the temperature limiter - 4 - and the contact c - of the thermostat or the temperature control device --3-- closed, and it is, as shown in the drawing, the radiator assembly - II - fed with the lower heating power. If, at the beginning of a charging period in the storage heater, the temperature falls below a certain, somewhat lower level, then contacts-b and c-of the thermostat or of the
 EMI2.1
 --3-- closed. Is - II- disconnected from the network and the radiator arrangement --I-- with the greater heating power is connected to the network.

   If, at the beginning of a charging period, the temperature falls below a certain lower temperature value, the contacts - a, b and c - of the thermostat - 3 - are closed and both the circuit breaker - l - and the circuit breaker - are speaking 2an, whereby both radiator assemblies-I and II-are connected to the network. In order to ensure continuous charging of the storage heater in spite of the opening of contacts-a and b-during the charging period, the circuit breakers -1 and 2 are with
 EMI2.2
    2'-provided. 2 - can drop so that only the weaker radiator arrangement - II - is connected to the mains.

   If the maximum permissible temperature is reached in spite of this reduction in the heating output, the temperature limiter also disconnects the radiator arrangement - II - from the mains.



   The contacts-a, b, c-controlling the drives of the circuit breakers can also belong to individual thermostats, the temperature response values of which are graded. These contacts do not have to be operated by a single drive.



   PATENT CLAIMS:
1. Charging control for electrical storage heaters, in which at least two partial load circuits are provided, each containing a radiator arrangement, in each of which a circuit breaker or a contactor is inserted automatically operated by a temperature control device depending on the temperature of the storage heater, the temperature response values of the individual circuit breakers actuating switching devices of the temperature control device staggered
 EMI2.3
 two part-load circuits (I, II) with different heating capacities is designed as a changeover switch, to which a line branch (8 ) connected.
