Abstract
Description
Die vorliegende Erfindung betrifft einen Wechselrichter, insbesondere einen für Solaranlagen geeigneten Wechselrichter, sowie ein Verfahren zum Abdichten des Wechselrichters.The The present invention relates to an inverter, in particular one for Solar systems suitable inverter, as well as a method of sealing of the inverter.
Wechselrichter für Solaranlagen sind dem Fachmann hinreichend bekannt. Sie umfassen ein Gehäuse zur Aufnahme der elektronischen Komponenten und eine Maßnahme zur Kühlung der Leistungsbauteile der elektronischen Komponenten.inverter for solar systems are well known to those skilled in the art. They include a housing for Inclusion of electronic components and a measure to cooling the power components of the electronic components.
Je nach Anwendungsfall des Wechselrichters ist dieser einer mehr oder weniger sauberen Umgebung ausgesetzt. Insbesondere im landwirtschaftlichen Bereich ist es aber wesentlich, dass der Wechselrichter eine ausreichende Schutzklasse aufweist, um zu verhindern, dass die zum Beispiel in Ställen existierenden aggressiven Gase ins Innere des Wechselrichtergehäuses gelangen und dort zu einer Korrosion der elektronischen Komponenten führen. Herkömmlicherweise wird daher das Wechselrichtergehäuse möglichst hermetisch abgedichtet, was zu einem komplizierteren und teureren Aufbau des Wechselrichters führt.ever after application of the inverter this is one more or exposed to less clean environment. Especially in the agricultural However, it is essential for the inverter to have sufficient Has protection class to prevent, for example, in Stables existing aggressive gases get into the interior of the inverter housing and lead to corrosion of the electronic components. traditionally, therefore becomes the inverter housing preferably hermetically sealed, resulting in a more complicated and expensive Structure of the inverter leads.
Aufgabe der vorliegenden Erfindung ist es daher, einen Wechselrichter mit einem ausreichenden Staub- und Gasschutz bei gleichzeitig einfachem Aufbau sowie ein Verfahren zum einfachen Abdichten eines Wechselrichters zu schaffen.task The present invention is therefore an inverter with a sufficient dust and gas protection with a simple design and a method for easily sealing an inverter to accomplish.
Diese Aufgabe wird gelöst durch einen Wechselrichter mit den Merkmalen des Anspruchs 1 bzw. ein Verfahren zum Abdichten eines Wechselrichters mit den Merkmalen des Anspruchs 5. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der jeweiligen Unteransprüche.These Task is solved by an inverter having the features of claim 1 or a method of sealing an inverter with the features of claim 5. Advantageous embodiments and developments The invention are the subject of the respective subclaims.
Der Wechselrichter weist ein Gehäuse zur Aufnahme der elektronischen Komponenten auf, und dieses Gehäuse weist wiederum einen Anschluss für eine Überdruckquelle auf, mit welcher im Innern des Gehäuses ein Überdruck erzeugt werden kann.Of the Inverter has a housing for receiving the electronic components, and this housing has turn a connection for a pressure source on, with which in the interior of the housing, an overpressure can be generated.
Aufgrund des Überdrucks im Innern des Gehäuses des Wechselrichters kann auf einfache Weise ein Eindringen von Staub und Gasen verhindert werden, wobei die Dichtigkeit des Gehäuses selbst geringer ausfallen kann. Der Aufbau des Wechselrichtergehäuses wird so vereinfacht und führt zu einer Senkung der Herstellungskosten.by virtue of of overpressure inside the case The inverter can easily prevent dust from entering and gases are prevented, with the tightness of the housing itself lower can fail. The structure of the inverter housing is so simplified and leads to a reduction in production costs.
Vorzugsweise wird im Innern des Gehäuses mittels der Überdruckquelle ein im Wesentlichen konstanter Überdruck erzeugt.Preferably is inside the case using the overpressure source a substantially constant overpressure generated.
Es hat sich gezeigt, dass bereits ein geringer Überdruck von weniger als 200 mbar ausreicht, um ein Eindringen von Staub und Gasen bei den üblichen Luftdruck- und Temperaturschwankungen zu verhindern.It has been shown to already have a low gauge pressure of less than 200 mbar is sufficient to allow penetration of dust and gases in the usual To prevent air pressure and temperature fluctuations.

Der oben beschriebene Wechselrichter kann in vorteilhafter Weise zum Beispiel für Solaranlagen verwendet werden. Er kann wegen seiner verbesserten Abdichtung insbesondere auch in schwierigen Umgebungen eingesetzt werden, wie beispielsweise landwirtschaftlichen Ställen, in denen aggressive Gase (z. B. Ammoniak) existieren, die bei herkömmlichen Wechselrichtern ohne hermetisch abgedichtetes Gehäuse insbesondere eine Korrosion der Kupferteile der elektronischen Komponenten hervorrufen.Of the The inverter described above can advantageously for example for Solar systems are used. He can because of his improved Sealing especially used in difficult environments such as agricultural stables, in which aggressive gases (eg ammonia) exist, which in conventional Inverters without hermetically sealed housing in particular cause corrosion of the copper parts of the electronic components.
