Description
Die vorliegende Erfindung betrifft eine Fotovoltaikanlage mit den Merkmalen des Oberbegriffs des unabhängigen Anspruchs 1 sowie eine Brandschutzsicherung für eine Fotovoltaikanlage.The The present invention relates to a photovoltaic system having the features the generic term of the independent Claim 1 and a fire protection for a photovoltaic system.
Fotovoltaikanlagen werden zur Erzeugung von elektrischer Energie durch Umwandlung von solarer Strahlungsenergie in vielfältigen Varianten eingesetzt. Bekannte Anordnungen sehen eine Vielzahl von einzelnen Fotovoltaikelementen vor, die bspw. auf Gebäudedächern oder auf Freiflächen aufgestellt und gruppiert sein können. Die einzelnen Elemente sind in der Regel in Gruppen in Serie geschaltet, so dass die bereitgestellte elektrische Gleichspannung zu einem Wechselrichter geleitet und in ein öffentliches Stromnetz eingespeist oder zu eigenen Verwendung bereitgestellt werden kann.photovoltaic panels are used to generate electrical energy by converting solar radiation energy used in many variants. Known arrangements see a plurality of individual photovoltaic elements in front, for example, on building roofs or in open spaces can be set up and grouped. The individual elements are usually connected in groups in series, so that the provided DC electrical voltage to a Inverters are fed and fed into a public grid or may be provided for its own use.
Im Schadens- oder Störfall, insbesondere bei Bränden, können die von der Anlage bereitgestellten elektrischen Spannungswerte jedoch zu Problemen führen, da bei den typischerweise auftretenden Brandtemperaturen die Leitungsisolierungen rasch verschmoren, so dass Kurzschlüsse entstehen können. Auftreffendes Löschwasser kann zusätzliche Probleme verursachen, da nicht isolierte Leitungsabschnitte in Verbindung mit dem Löschwasser zu Funkenüberschlägen führen können. Die Brandbekämpfung ist deshalb schwierig und für die Feuerwehrleute gefährlich. Zudem ist für die Brandbekämpfer nicht erkennbar, ob eine potenzielle Gefährdung durch stromführende offene Leitungen vorliegt oder nicht.in the Damage or accident, especially in fires, can the electrical voltage levels provided by the system but cause problems because at the typically occurring fire temperatures, the line insulation quickly spotted, leaving shorts can arise. Impinging extinguishing water can be extra Cause problems as uninsulated pipe sections connect with the extinguishing water too Sparking flashovers. The Firefighting is therefore difficult and for the firefighters dangerous. In addition, is for the firefighters not detectable, whether a potential hazard from live open Lines present or not.
Ein Ziel der vorliegenden Erfindung besteht darin, eine Sicherung für Fotovoltaikanlagen zur Verfügung zu stellen, die im Störfall, insbesondere bei auftretenden Bränden, eine Gefährdung der Brandbekämpfer zuverlässig verhindern kann.One The aim of the present invention is a fuse for photovoltaic systems to disposal in the event of a fault, especially when fires occur, a danger the fire-fighter reliable can prevent.
Dieses Ziel der Erfindung wird mit dem Gegenstand des unabhängigen Anspruchs erreicht. Merkmale vorteilhafter Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.This The aim of the invention is the subject of the independent claim reached. Features of advantageous developments of the invention result from the dependent ones Claims.
Eine erfindungsgemäße Fotovoltaikanlage umfasst wenigstens ein Fotovoltaikelement zur Dach- oder Freiflächenmontage und eine elektrische Verbindungsleitung zur Übertragung von Gleichspannung zu einer elektrischen Übergabestelle. Die Erfindung sieht eine thermische Sicherung in der elektrischen Verbindungsleitung zwischen dem wenigsten einen Fotovoltaikelement und der elektrischen Übergabestelle vor. Die thermische Sicherung sorgt für eine Unterbrechung der Leitungsverbindung und damit der elektrischen Leitung bei einer definierbaren Grenztemperatur, typischerweise bei einer Temperatur, wie sie bei Bränden auftritt. Die erfindungsgemäße thermische Sicherung ermöglicht somit eine effektive Brandsicherung und verhindert dadurch, dass bei einem Gebäude- oder Anlagebrand das Verschmoren von elektrischen Leitungsisolierungen zur Spannungsüberschlägen, Funkenflug oder Kurzschlüssen führen kann, wodurch Brandbekämpfer wie Feuerwehrleute erheblich gefährdet werden können.A Photovoltaic plant according to the invention comprises at least one photovoltaic element for roof or open space installation and an electrical connection line for transmission of DC voltage to an electrical transfer point. The invention provides a thermal fuse in the electrical Connecting line between the least one photovoltaic element and the electrical transfer point in front. The thermal fuse ensures that the line connection is interrupted and thus the electrical line at a definable limit temperature, typically at a temperature such as occurs in fires. The inventive thermal Backup possible thus an effective fire safety and thereby prevents at a building or plant fire the fouling of electrical wire insulations for flashovers, flying sparks or short circuits to lead can, making firefighters like Firefighters seriously endangered can be.
Als Thermosicherung kann insbesondere eine Schmelzsicherung zum Einsatz kommen, die bei einer von außen aufgebrachten Grenztemperatur von bspw. 180° C bis 220° C zu einer Unterbrechung einer elektrischen Verbindung führen kann. Die Grenztemperatur ist vorzugsweise so zu wählen, dass einerseits die hohen Temperaturen, die bei intensiver Sonneneinstrahlung auf die Kollektorflächen einwirken, nicht zu einer Unterbrechung der Leitungsverbindung führen, andererseits jedoch bei einem Brand eine Unterbrechung gewährleistet ist.When Thermal fuse can be used in particular a fuse come in from outside applied limit temperature of eg. 180 ° C to 220 ° C to interrupt a lead electrical connection can. The limit temperature is preferably to be selected such that on the one hand, the high temperatures, which in intense sunlight act on the collector surfaces, not lead to an interruption of the line connection, on the other hand However, a break in a fire is guaranteed.
Vorzugsweise ist innerhalb einer Serienschaltung von mehreren Fotovoltaikelementen wenigstens eine Thermosicherung vorgesehen. Von Vorteil ist es, wenn innerhalb einer Gruppe von Fotovoltaikelementen, die mittels einer Thermosicherung von einer weiteren Gruppe von Fotovoltaikelementen getrennt ist, eine Teilspannung von maximal 120 Volt abfällt. Bis zu einer solchen Teilspannung ist die Gefahr von Funkenüberschlägen noch relativ gering, während oberhalb dieser Grenzspannung eine Gefährdung von Personen droht, die zur Brandbekämpfung eingesetzt sind.Preferably is within a series connection of several photovoltaic elements at least one thermal fuse provided. It is an advantage if within a group of photovoltaic elements by means of a thermal fuse separated from another group of photovoltaic elements is, a partial voltage of a maximum of 120 volts drops. Up to such a partial voltage the risk of flashovers is still relatively low while above this limit voltage threatens a danger to persons, the fire fighting are used.
Eine weitere Ausführungsvariante sieht vor, dass jeweils Gruppen von in Serie geschalteten Fotovoltaikelementen endseitig mit wenigstens einer Thermosicherung versehen sind. Insbesondere kann an jedem Leitungsanschluss einer Gruppe von in Serie geschalteten Fotovoltaikelementen jeweils eine Thermosicherung angeordnet sein. Mit mehreren solcher Thermosicherungen ist somit eine ausreichende Brandsicherung ermöglicht.A further embodiment provides that each groups of photovoltaic elements connected in series end provided with at least one thermal fuse. Especially can be connected to each line terminal of a group of series Photovoltaic elements are each arranged a thermal fuse. With several such thermal fuses is thus a sufficient fire safety allows.
Eine erfindungsgemäße Ausführungsform sieht vor, dass die Thermosicherung als Unterbrechungskontakt oder -schalter ausgebildet ist, der bei einer definierbaren Grenztemperatur einen Leitungskontakt dauerhaft trennt. Die Thermosicherung kann insbesondere als Schmelzsicherung o. dgl. ausgebildet sein. Diese Schmelzsicherung kann insbesondere ein zylindrisches Gehäuse mit einer darin angeordneten vorgespannten Spiralfeder umfassen, deren vorgespanntes Ende mit einer Weichlotverbindung in einer der Stirnseiten des Gehäuses verankert ist, so dass bei Schmelzen des Weichlots die Spiralfeder entspannt und die elektrische Verbindung getrennt wird.A sees embodiment of the invention ago that the thermal fuse as a break contact or switch is formed, the at a definable limit temperature a Line contact permanently disconnects. The thermal fuse can in particular be designed as a fuse o. The like. This fuse In particular, a cylindrical housing with one disposed therein Preloaded coil spring include, whose biased end with a Weichlotverbindung anchored in one of the end sides of the housing is, so that when melting the soft solder, the coil spring relaxes and the electrical connection is disconnected.
Die Schutzhülse kann bspw. aus Kunststoff oder Keramik bestehen, die Spiralfeder vorzugsweise aus einem elektrisch gut leitfähigen Material wie eine Kupferlegierung. Mit der Legierung des Weichlots kann die Schmelztemperatur definiert und auf einen sinnvollen Schmelzpunkt von ca. 180° C bis ca. 220 ° C eingestellt werden, die bei auftretenden Bränden für eine zuverlässige Trennung der elektrischen Verbindung sorgen kann. Wahlweise kann auch eine geeignete Schmelzpille zum Einsatz kommen, mittels derer die vorgespannte Spiralfeder unter Herstellung eines elektrischen Leitungskontakts verankert ist, so dass sie bei einer definierten Grenztemperatur gelöst und entspannt wird, wobei der elektrische Kontakt dauerhaft getrennt wird.The protective sleeve can, for example, made of plastic or ceramic, the coil spring preferably made of a highly electrically conductive material such as a copper alloy. With the alloy of the soft solder, the melting temperature can be defined and set to a reasonable melting point of about 180 ° C to about 220 ° C, which can provide a reliable separation of the electrical connection in fires occurring. Alternatively, a suitable fusion pellet can be used, by means of which the prestressed coil spring is anchored to produce an electrical line contact, so that it is dissolved and relaxed at a defined limit temperature, the electrical contact is permanently disconnected.
Eine besonders vorteilhafte Variante der Brandschutzsicherung sieht vor, dass die thermische Sicherung in eine Steckverbindung integriert sein kann, die in eine vorhandene Steckverbindungsleitung eingefügt werden kann. Die thermische Sicherung kann bspw. in einem kurzen Steckerabschnitt angeordnet sein, der zwischen eine Steckverbindung eingefügt und somit in jede Verbindungsleitung nachträglich integriert werden kann. Damit ist grundsätzlich ein Einbau in jeder Steckverbindung möglich, wodurch auch die Nachrüstung von Altanlagen problemlos sichergestellt ist. Wahlweise kann die Thermosicherung auch in einem Fotovoltaikelement, in einem Schaltkasten und/oder innerhalb der Leitungsverbindung angeordnet bzw. dort integriert sein.A particularly advantageous variant of the fire protection system provides that the thermal fuse integrated into a connector which can be inserted into an existing connector line can. The thermal fuse can be arranged, for example, in a short connector section be inserted between a connector and thus in each connection line later can be integrated. This is basically an installation in each Plug connection possible, whereby also the retrofitting of old systems is easily ensured. Optionally, the Thermal fuse also in a Fotovoltaikelement, in a control box and / or disposed within the line connection or integrated there be.
Auf die beschriebene Weise ist ein vollständiger Schutz durch eine sichere Stringabschaltung im Brandfall ermöglicht. Durch mehrere Brandschutzsicherung im String, bspw. nach jedem dritten Modul, kann die Generatorspannung unter ein gefahrdrohendes Maß reduziert werden. Grundsätzlich ist die Konstruktion auf alle gängigen Fotovoltaik-Steckverbinder übertragbar.On the manner described is complete protection by a secure String shutdown possible in case of fire. Through several fire protection in the string, for example after every third module, the generator voltage can reduced to a dangerous level become. in principle is the construction on all common Photovoltaic connector transferable.
Die thermische Sicherung ist vorzugsweise so auszulegen, dass sie mit Strömen von wenigstens zehn Ampere belastet werden kann und eine Spannungsfestigkeit von mehr als 1000 Volt aufweist. Auf diese Weise wird ein Spannungsüberschlag auch bei Spannungen von bis zu 1000 Volt zuverlässig verhindert. Die Auslösetemperatur kann in gewünschten Grenzen eingestellt werden, indem bspw. eine geeignete Lotverbindung oder Schmelzverankerung der Feder ausgewählt wird.The Thermal fuse is preferably to be interpreted as having Stream can be loaded by at least ten amps and a dielectric strength of more than 1000 volts. In this way, a voltage flashover reliably prevented even at voltages of up to 1000 volts. The triggering temperature can be within desired limits be set by, for example, a suitable solder joint or Fused anchorage of the spring is selected.
