Abstract
PVA
Vorrichtung zur löschtechnischen
Spannungsfreischaltung von Photovoltaikanlagen zur Ermöglichung
des Einsatzes von Löschmitteln. PVA-Vorrichtung
(
Description
Photovoltaikanlagen (PVA) üblicher Bauart bestehen meist aus einer oder mehrer elektrochemischen Zellen zur Spannungserzeugung. Diese sog. Solarzellen sind sowohl auf privaten als auch auf öffentlichen Gebäuden montiert und koppeln die durch Licht erzeugte Spannung ans öffentliche elektrische Netz an. Zur Spannungsnutzung werden daher elektrische Leiter aus der PVA nach außen, an das elektrische Netz des Gebäudes, oder und an das öffentliche Netz geführt.photovoltaic systems (PVA) more common Type usually consist of one or more electrochemical cells for voltage generation. These so-called solar cells are both private as well as on public buildings mounted and couple the voltage generated by light to the public electrical network. For voltage use therefore electrical Ladder out of the PVA to the outside, to the electrical network of the building, or and to the public Network led.
Der in den Schutzansprüchen angegeben Erfindung liegt das Problem zugrunde, dass im Falle eines Brandes der Einsatz von Löschmitteln aufgrund der an der PVA auftreten hohen Spannung nicht möglich ist.Of the in the protection claims The invention is based on the problem that in the case of Fire the use of extinguishing agents due to the high voltage occurring at the PVA is not possible.
Dieses Problem wird durch die in den Schutzansprüchen aufgeführten Merkmale gelöst.This Problem is solved by the features listed in the claims.
Mit der Erfindung wird erreicht, dass die PVA in so weit spannungsfrei geschaltet wird, dass der Einsatz von Löschmitteln ermöglicht wird.With The invention achieves that the PVA in so far tension-free is switched, that the use of extinguishing agents is made possible.

Ausführungsbeispiel
der Erfindung wird anhand der
Den weiteren Schutzansprüchen liegt das Problem zugrunde, dass auch im Falle einer notwendigen Reparatur oder/und Instandhaltung des öffentlichen elektrischen Netzes/des elektrischen Gebäudenetzes eine sichere Spannungsfreischaltung zwingend notwendig ist, um Gefahren zu vermeiden und Sicherheitsvorschriften zu genügen.The further protection claims the problem is that even in the case of a necessary Repair and / or maintenance of the public electrical network / electrical building network a safe disconnection is absolutely necessary to hazards to avoid and comply with safety regulations.
Dieses Problem wird mit den weiteren Schutzansprüchen gelöst.This Problem is solved with the further claims.
