Safety of power conversion equipment for use in photovoltaic power systems - Part 1: General requirements

This part of IEC 62109 applies to the power conversion equipment (PCE) for use in Photovoltaic (PV) systems where a uniform technical level with respect to safety is necessary.
This standard defines the minimum requirements for the design and manufacture of PCE for protection against electric shock, energy, fire, mechanical and other hazards.
This standard provides general requirements applicable to all types of PV PCE. There are additional parts of this standard that provide specific requirements for the different types of power converters, such as Part 2 - inverters. Additional parts may be published as new products and technologies are commercialised.

l'IEC 62109-1:2010 s'applique aux équipements de conversion de puissance (PCE – power conversion equipment en anglais) utilisés dans les systèmes photovoltaïques (PV) nécessitant un niveau technique uniforme en matière de sécurité. La présente norme définit les exigences minimales relatives à la conception et à la fabrication de PCE pour la protection contre les chocs électriques, les risques liés à l'électricité, les incendies, les dangers mécaniques et autres dangers. La présente norme fournit des exigences générales applicables à tous les types d'équipement de conversion de puissance photovoltaïque (PV PCE).

Varnost močnostnih pretvornikov, ki se uporabljajo v fotonapetostnih sistemih - 1. del: Splošne zahteve (IEC 62109-1:2010 (EQV))

Ta del IEC 62109 velja za močnostne pretvornike, ki se uporabljajo v fotonapetostnih sistemih, pri katerih je potrebna enotna tehnična raven glede varnosti.
Ta standard opredeljuje minimalne zahteve za projektiranje in izdelavo močnostnih pretvornikov za zaščito pred elektrošokom, energijo, požarom, mehanskimi in drugimi nevarnostmi.
Ta standard zagotavlja splošne zahteve, ki veljajo za vse vrste fotonapetostnih močnostnih pretvornikov. Dodatni deli tega standarda zagotavljajo posebne zahteve za različne vrste močnostnih pretvornikov, kot je 2. del - razsmerniki. Dodatni deli se lahko objavljajo, ko na trg pridejo novi proizvodi in tehnologije.
