Description
Die Erfindung bezieht sich auf einen an das Wechselspannungsnetz angeschlossenen Heizstromverbraucher, dessen Leistung durch vorgeschaltete steuerbare Gleichrichter im Bereich bis zur Vollast stetig veränderbar ist.The invention relates to an alternating voltage network connected heating current consumer, whose output is controlled by upstream controllable Rectifier in the range up to full load is continuously changeable.
Bei allgemein bekannten Schaltungen dieser Art werden steuerbare Ventile verwendet, die in Antiparallelschaltung sowohl eine Anschnittssteuerung der negativen als auch der positiven Halbwelle der sinusförmigen Netz-Wechsel spannung zulassen. Hierfür sind auch symmetrische Thyristoren geeignet, welche die Antiparallelschaltung in sich vereinigen.In generally known circuits of this type, controllable valves are used which are connected in anti-parallel both a gate control of the negative as well as the positive half-wave of the sinusoidal Allow mains alternating voltage. Symmetrical thyristors are also suitable for this, which unite the anti-parallel connection.
Der Erfindung liegt die Aufgabe zugrunde, einen Heizstromverbraucher der eingangs genannten Art so zu gestalten, daß der insbesondere für Heizstromverbraucher kleiner Leistung beträchtliche Aufwand zur Steuerung der Verbraucherspannung verringert wird.The invention has for its object to be a Make heating current consumers of the type mentioned so that the particular for heating current consumers low power reduces the effort required to control the consumer voltage will.
Die Erfindung besteht darin, daß der Heizstromverbraucher für eine Nennspannung vom etwa χ\ψϊ-fachen der vorgesehenen Netz-Wechselspannung ausgelegt ist und daß in die Netzzuleitung lediglich ein einziges in nur einer Stromrichtung stromdurchlässiges steuerbares Ventil geschaltet ist.The invention consists in that the heating current consumer is designed for a nominal voltage of about χ \ ψϊ- times the intended mains alternating voltage and that only a single controllable valve permeable in only one current direction is connected to the mains supply line.
Es sind auch Schaltungen bekannt, bei denen nur ein einziges, in einer Stromrichtung durchlässiges steuerbares Ventil verwendet wird (Buch »Silicon Controlled Rectifier Manual«, 1961, General Electric Comp. New York, S. 124 bis 126, oder auch Buch von W. T a e g e r , »Steuerungs- und Regeltechnik«, Francksche Verlagshandlung W. Keller & Co., 1963, S. 42).Circuits are also known in which only a single one, which is permeable in one current direction controllable valve is used (book "Silicon Controlled Rectifier Manual", 1961, General Electric Comp. New York, pp. 124 to 126, or also book by W. T a e g e r, »Control and regulation technology«, Francksche Verlagshandlung W. Keller & Co., 1963, p. 42).
Dabei wird ein Verbraucher im Bereich von Null bis zu einem Maximalwert stetig in seiner Leistungsaufnahme eingestellt. Über die Auslegung des Verbrauchers bezüglich seiner Nennspannung ist dort nichts ausgesagt.A consumer is continuously adjusted in its power consumption in the range from zero to a maximum value. About the interpretation of the consumer nothing is stated there with regard to its nominal voltage.
Durch die Erfindung werden nicht nur der schaltungstechnische Aufwand für die Steuerungselemente sowie die Anzahl der Bauteile kleiner, sondern auch für den Verbraucher wirkt sich die niedrigere Nennspannung vorteilhaft aus. Bei Heizwendeln wird die Länge des Drahtes kleiner, während der Querschnitt größer wird. Dadurch ergeben sich eine größere Festigkeit und Haltbarkeit.The invention not only reduces the complexity of the circuitry for the control elements As well as the number of components is smaller, the lower rated voltage also affects the consumer advantageous. With heating coils, the length of the wire is smaller, while the cross-section gets bigger. This results in greater strength and durability.
Die Wirkungsweise und Einzelheiten der Erfindung werden an einem Schaltbild erläutert.The mode of operation and details of the invention are explained using a circuit diagram.
F i g. 1 zeigt das vereinfachte Schaltbild eines erfindungsgemäßen Heizstromverbrauchers.F i g. 1 shows the simplified circuit diagram of an inventive Heating current consumer.
F i g. 2 zeigt einstellbare Kurvenformen der am Verbraucher liegenden Speisespannung.
Der Verbraucher 1 mit dem in Reihe geschalteten Thyristor 2 ist an die Netzspannung Un angeschlossen.
Durch das Steuergerät 3 wird der Thyristor 2 über seine Steuerelektrode 4 anschnittsgesteuert. Die am
Verbraucher liegende Spannungszeitfläche kann vonF i g. 2 shows adjustable waveforms of the supply voltage applied to the consumer.
The consumer 1 with the series-connected thyristor 2 is connected to the mains voltage Un . The thyristor 2 is gated-controlled by the control device 3 via its control electrode 4. The voltage time area at the consumer can be from
ίο Null über einen mittleren Wert nach F i g. 2 b bis zum
Maximum nach F i g. 2 a geregelt werden. Der maximal mögliche Effektivwert der Kurvenform nach F i g. 2 a
ist gerade das VyT-fache der Netzspannung Un. Für
diese reduzierte Netzspannung ist der Verbraucher ausgelegt. Deshalb kann man auf die Durchschaltung
auch der 2. Halbwelle einer Sinuswelle verzichten, wobei trotzdem eine Aussteuerung des Stromverbrauchers
auf seine volle Nennspannung möglich ist.
Das Steuergerät 3 kann in beliebig bekannter Art ausgeführt werden. Es kann manuell betätigt werden,
oder auch durch automatische Regelgrößen, wie beispielsweise die Temperatur eines Heizlüfters.ίο zero over a mean value according to F i g. 2 b up to the maximum according to FIG. 2 a. The maximum possible effective value of the curve shape according to FIG. 2 a is just VyT times the line voltage U n . The consumer is designed for this reduced mains voltage. This is why you can do without the second half-wave of a sine wave, although it is still possible to drive the power consumer to its full rated voltage.
The control device 3 can be designed in any known manner. It can be operated manually or by automatic control variables, such as the temperature of a fan heater.
Einen weiteren Vorteil bietet die Erfindung, wenn man einen Schalter 5 nach F i g. 1 vorsieht, welchen man wahlweise handbetätigt oder auch automatisch schließen kann. Dadurch kann man kurzzeitig dem Stromverbraucher die doppelte Leistung zuführen, weil dann die volle Wechselspannung mit beiden Sinushalbwelleri, wie in Bild 2 c, am Verbraucher liegt.The invention offers a further advantage if one uses a switch 5 according to FIG. 1 provides which you can choose to close manually or automatically. This can be used for a short time Feed electricity consumers twice the power, because then the full AC voltage with both Sinus half-wave, as in Figure 2 c, is on the consumer.
In dieser Weise lassen sich Anheizzeiten verkürzen.In this way, heating-up times can be shortened.
