Abstract

Temperature controller prevents overheating of a solar system whilst the current supply of a photovoltaic module is interrupted to guarantee the safety of the system. Preferred Features: A bimetal pre-aged by tempering and arranged in a porcelain housing is fixed using sheet metal clips to interrupt the current supply at 100[deg] C. The controller is arranged in or close to the collector unit.

Description

Übertemperaturwächter für Globalstrahlungsbetriebene Solarthermische Kollektoreinheiten Der Übertemperaturwächter (1) besteht aus einem der Aufgabe angepasstem Thermostat. Hier sind zwei der Aufgabe entspechende Ausführungen vorgesehen. Beide Ausführungen sind mit einem vorgetemperten Bimetall ausgestattet, welcher eine gleichbleibende und dauerhafte Schaltfunktion gewährleistet. Findet die Temperaturüberwachung innerhalb des Kollektors statt, wird ein Keramikthermostat mittels Blechklips an den Rücklauf im Kollektor- Sammlergehäuse angeordnet. Wird das Thermostat in einer von aussen zugänglichen Fühlerhülse positioniert, so ist das Bimetall des Wächters in einer versiegelten Blechhülse untergebracht. In beiden Ausführungen wird der Leiter der stromerzeugenden Einheit mit dem Thermostat geschaltet. Um ein Überhitzen des Solarspeichersystems zu verhindern, wird die Stromzufuhr der Pumpe unterbrochen (Eigensicherheit). Dies geschieht bei konventionellen Systemen mittels Solarregler, der die Temperatur des Solarspeichers und-/oder des Kollektors erfasst und bei Übertemperatur die Stromzufuhr unterbricht. Mit der Einführung Globalstrahlungs-betriebenen Kollektorsystemen, die in der Regel ohne Netzstromanschluss, Fühler und Temperatur-Differehzregelung betrieben werden, ist die Eigensicherheit des System sicherzustellen. Dies wird mit dem Übertemperaturwächter realisiert. Dieser unterbricht bei 100°C die Stromzufuhr, so das der Kollektor in Stillstand versetzt wird. Ist der Kollektorinhalt verdampft, ist eine Überhitzung des Speichers nicht mehr möglich und die Eigensicherheit des Systems ist somit gewährleistet. Ein Wiederanlaufen der Pumpe ist, solange der Kollektor leer ist, nicht möglich, da die Stromzufuhr erst wieder erfolgt, wenn der Übertemperaturwächter eine Temperatur von 95 °C misst.Overtemperature monitor for global radiation powered Solar thermal collector units The overtemperature monitor (1) consists of a thermostat adapted to the task. Here are two the task entspechende versions intended. Both versions are equipped with a pre-annealed bimetal, which is a consistent and permanent switching function guaranteed. Finds the temperature monitor inside the collector, a ceramic thermostat is using Sheet metal clips on the return in collector collector housing arranged. If the thermostat is accessible from the outside Sensor sleeve positioned, such is the bimetal of the watchman in a sealed sheet metal sleeve accommodated. In both versions becomes the head of the electricity generating unit with the thermostat connected. To overheat the Solar storage system to prevent the power supply to the pump interrupted (intrinsic safety). This happens with conventional Systems by means of solar controller, the temperature of the solar storage and / or the collector detected and at excess temperature, the power supply interrupts. With the introduction Global radiation-driven collector systems, usually without mains connection, sensor and temperature-Differehzregelung is intrinsic safety of the system. This is realized with the overtemperature monitor. This interrupts at 100 ° C the power supply, so that the collector is stopped. is the collector contents evaporate, an overheating of the memory is not more is possible and the intrinsic safety of the system is thus ensured. A restart of the pump is, as long as the collector is empty, not possible, because the power supply is only again when the overtemperature monitor a Temperature of 95 ° C measures.
