Einrichtung zur zeitlich begrenzten Erhöhung der Heizleistung einer BelagsheizungsanordnungDevice for temporarily increasing the heating power of a covering heating arrangement
Gegenstand der Erfindung ist eine Einrichtung zur zeitlich begrenzten Erhöhung der Heizleistung einer Belagsheizungsanordnung, insbesondere einer Heizungsanordnung eines Straßen- oder Brückenbelages, bei gegebenem Anschlußwert dieser Heizungeanordnung an das elektrische Energieversorgungsnetz.The invention relates to a device for a time-limited Increasing the heating power of a surface heating arrangement, in particular a heating arrangement of a street or Bridge covering, with a given connection value of this heating arrangement to the electrical power supply network.
Heizungsanordnungen dieser Art sind schon an zahlreichen kritischen Stellen des Straßennetzes im Betrieb, um ein plötzliches Vereisen dieser Stellen und damit Unfälle zu vermeiden. Solche Anordnungen haben jedoch einen hohen Energiebedarf, und es ist daher wünschenswert, daß mit der Heizleistung spar-Heating arrangements of this type are already critical to numerous Place the road network in operation in order to prevent these areas from suddenly icing over and thus accidents. However, such arrangements have a high energy requirement, and it is therefore desirable that the heating power is

sam umgegangen wird. Andererseits wird von einer solchen Heizungsanordnung erwartet, dass sie den Belag auch bei sehr tiefen Temperaturen einwandfrei von Schnee und Eis freihält. Dies bedingt bei den üblichen elektrischen Heizungsanordnungen einen hohen Anschlusswert an das Energieversorgungsnetz und damit aufwendige Installationen, die in den seltensten Fällen voll ausgenützt werden.sam is handled. On the other hand, it is expected of such a heating arrangement that they also cover the floor with very keeps snow and ice perfectly free of snow and ice at low temperatures. This is necessary with the usual electrical heating arrangements a high connection value to the power supply network and thus complex installations that are in the in the rarest cases are fully exploited.
Es ist daher vorteilhafter, wenn man den Anschlusswert so festlegt, dass er dem üblicherweise benötigten Energiebedarf entspricht. Die Belagsheizungsanordnung muss aber trotzdem imstande sein, den erwähnten, aussergewöhnlichen Bedingungen genügen zu können und die dafür notwendige Heizleistung abgeben zu können.It is therefore more advantageous to set the connection value in such a way that that it corresponds to the energy requirements usually required. The covering heating arrangement must, however, still be capable be able to meet the extraordinary conditions mentioned and provide the necessary heating power to be able to.
Hierfür eignet sich erfindungsgemäss die eingangs erwähnte Einrichtung, welche gekennzeichnet ist durch eine vom Energieversorgungsnetz unabhängige Energiequelle, welche durch eine Messvorrichtung gesteuert wird und bei einer von der Messvorrichtung den Anschlusswert überschreitenden Heizleistung die zusätzliche Heizleistung in die Belagsheizungsanordnung einspeist.According to the invention, the one mentioned at the beginning is suitable for this Device which is characterized by an energy source that is independent of the energy supply network and which is provided by a Measuring device is controlled and when the measuring device exceeds the connected load heating power feeds the additional heating power into the covering heating arrangement.
Ein Ausführungsbeispiel dieser Einrichtung ist anhand eines Anschlussschemas aus der beiliegenden Zeichnung ersichtlich.An exemplary embodiment of this device is shown in the accompanying drawing using a connection diagram.
Die Einrichtung besteht aus Belags- und Meteorologie-Sonden 1, einer Verstärkereinheit 2, einer zentralen Rechen- und Steuereinheit 3, einer Zusatzenergiequelle 4 und einem Spannungswandler 5, einer Aufschalteinheit 6, einem Leistungsschalter und der eigentlichen Belagsheizungsanordnung 8. Sie ist an das örtliche Energienetz 9 mit den Phasenleitern R, S, T angeschlossen. The device consists of surface and meteorological probes 1, an amplifier unit 2, a central computing and control unit 3, an additional energy source 4 and a voltage converter 5, a connection unit 6, a circuit breaker and the actual covering heating arrangement 8. It is connected to the local energy network 9 with the phase conductors R, S, T.
Aufgrund der Signale der Sonden 1 errechnet die zentrale Steuer-On the basis of the signals from the probes 1, the central control

einheit 3 die notwendige Heizleistung, um die Bildung einer Eis- oder Schneeschicht auf der Belagsoberfläche zu verhindern. Ist die verlangte Leistung grosser als der maximale Anschlusswert der Belagsheizungsanordnung an das Energieversorgungsnetz , so wird die Spannung an der Heizungsanordnung kurzfristig erhöht. Zu diesem Zweck schaltet die Steuereinheit 3 über die Aufschalteinheit 6 die zusätzliche Energiequelle 4 ein, welche über den Spannungswandler 5 die Spannung am Leistungsschalter 7 über diejenige des Netzes 9 erhöht. Die genannte Leistung der Heizungsanordnung beträgt nun:unit 3 the necessary heating power to prevent the formation of a layer of ice or snow on the surface of the pavement. If the required power is greater than the maximum connection value of the covering heating arrangement to the energy supply network , the voltage on the heating arrangement is increased for a short time. To this end, the Control unit 3 via the connection unit 6 the additional Energy source 4, which via the voltage converter 5, the voltage at the circuit breaker 7 over that of the network 9 increased. The stated output of the heating arrangement is now:
P=P + N ALTP = P + N OLD
P = GesamtleistungP = total power
U = ZusatzspannungU = additional voltage
P = NetzanschlussleistungP = grid connection power
R = HeizungswxderstandR = heating resistance
Diese Aufschaltung wird von der zentralen Steuereinheit kontrolliert. Als Energiequelle 4 wird mit Vorteil eine Batteriegruppe oder eine von einem Verbrennungsmotor angetriebene Generatorgruppe eingesetzt.This activation is controlled by the central control unit. A battery group or one driven by an internal combustion engine is advantageously used as the energy source 4 Generator group used.
