Low-voltage surge protective devices - Part 31: Requirements and test methods for SPDs for photovoltaic installations
IEC 61643-31:2018 is applicable to Surge Protective Devices (SPDs), intended for surge protection against indirect and direct effects of lightning or other transient overvoltages. These devices are designed to be connected to the DC side of photovoltaic installations rated up to 1 500 V DC. These devices contain at least one non-linear component and are intended to limit surge voltages and divert surge currents. Performance characteristics, safety requirements, standard methods for testing and ratings are established. SPDs complying with this standard are exclusively dedicated to be installed on the DC side of photovoltaic generators and the DC side of inverters. SPDs for PV systems with energy storage (e.g. batteries, capacitor banks) are not covered. SPDs with separate input and output terminals that contain specific series impedance between these terminal(s) (so called two-port SPDs according to IEC 61643-11:2011) are not covered. SPDs compliant with this standard are designed to be permanently connected where connection and disconnection of fixed SPDs can only be done using a tool. This standard does not apply to portable SPDs Keywords: photovoltaic installations, lightning or other transient overvoltages

Parafoudres basse tension - Partie 31: Parafoudres pour usage spécifique y compris en courant continu - Exigences et méthodes d'essai des parafoudres pour installations photovoltaïques
IEC 61643-31:2018 est applicable aux parafoudres (SPD) de protection contre les effets indirects et directs de la foudre ou contre les surtensions transitoires. Ces dispositifs sont conçus pour être connectés en courant continu aux installations photovoltaïques de tension continue assignée jusqu’à 1 500 V. Ces dispositifs comportent au moins un composant non linéaire et sont utilisés pour limiter les surtensions et écouler les courants de foudre. Les caractéristiques de fonctionnement, les exigences de sécurité, les méthodes normalisées d'essai ainsi que les valeurs assignées applicables sont définies. Les parafoudres conformes à la présente norme sont exclusivement destinés à être installés en courant continu sur les générateurs photovoltaïques et en courant continu sur les onduleurs. Les parafoudres pour systèmes photovoltaïques (systèmes PV) avec stockage d’énergie (par exemple, les batteries d’accumulateurs, les batteries de condensateurs) ne sont pas couverts. Les parafoudres équipés de bornes d’entrée et de sortie séparées (désignés comme des parafoudres à deux ports selon l’IEC 61643-11:2011) avec une impédance série spécifique entre ces bornes ne sont pas couverts. Les parafoudres conformes à la présente norme sont conçus pour être raccordés de façon permanente lorsque la connexion et la déconnexion des parafoudres installés à poste fixe ne peuvent s’effectuer que par l’intermédiaire d’un outil. La présente norme ne s’applique pas aux parafoudres portables. Mots clés: installations photovoltaïques , foudre ou contre les surtensions transitoires
Nizkonapetostne naprave za zaščito pred prenapetostnimi udari - 31. del: Naprave za zaščito pred prenapetostnimi udari za posebno uporabo vključno z enosmernim tokom - Zahteve in preskusne metode za SPD za fotonapetostne inštalacije
Ta del standarda IEC 61643 se uporablja za naprave za zaščito pred prenapetostnimi udari (SPD) v primeru posrednih in neposrednih učinkov strele ali drugih prehodnih prenapetosti.
Te naprave so zasnovane za priklop na fotonapetostne inštalacije z enosmernim tokom do 1500 V.
Te naprave vsebujejo vsaj eno nelinearno komponento ter so namenjene omejitvi sunkov napetosti in preusmeritvi toka. Določene so značilnosti delovanja, varnostne zahteve, standardne metode za preskušanje in vrednosti.
Naprave za zaščito pred prenapetostnimi udari, ki so v skladu s tem standardom, so namenjene izključno za namestitev na enosmerno stran fotonapetostnih generatorjev in pretvornikov.
Naprave za zaščito pred prenapetostnimi udari za fotonapetostne sisteme s shranjevanjem energije (npr. baterije, kondenzatorske baterije) niso zajete.
Naprav za zaščito pred prenapetostnimi udari z ločenimi vhodnimi in izhodnimi terminali, ki vsebujejo posebno vzdolžno impedanco med temi terminali (v skladu s standardom IEC 61643-11:2011 t. i. naprava za zaščito pred prenapetostnimi udari z dvoje vrati), zahteve tega standarda ne zajemajo.
Naprave za zaščito pred prenapetostnimi udari, skladne s tem standardom, so zasnovane tako, da so trajno povezane, če je omenjene fiksne naprave mogoče povezati in ločiti samo z orodjem. Ta standard se ne uporablja za prenosne naprave za zaščito pred prenapetostnimi udari.
OPOMBA 1: Na splošno naprave za zaščito pred prenapetostnimi udari za fotonapetostne aplikacije ne vsebujejo specifične vzdolžne impedance med vhodnimi/izhodnimi terminali zaradi zadržkov v zvezi z električno učinkovitostjo.
OPOMBA 2: Kadar koli se v tem dokumentu sklicuje na električni ali napajalni sistem, se to nanaša na enosmerno stran fotonapetostne inštalacije.

Annex ZZ
(informative)
Relationship between this European standard and the safety objectives of Directive
2014/35/EU [2014 OJ L96] aimed to be covered
This European standard has been prepared under a Commission’s standardisation request relating to
harmonised standards in the field of the Low Voltage Directive, M/511, to provide one voluntary means of
conforming to safety objectives of Directive 2014/35/EU of the European Parliament and of the Council of 26
February 2014 on the harmonisation of the laws of the Member States relating to the making available on the
market of electrical equipment designed for use within certain voltage limits [2014 OJ L96].
Once this standard is cited in the Official Journal of the European Union under that Directive, compliance
with the normative clauses of this standard given in Table ZZ.1 confers, within the limits of the scope of this
standard, a presumption of conformity with the corresponding safety objectives of that Directive, and
associated EFTA regulations.
