EN 50539-11:2013

Low-voltage surge protective devices - Surge protective devices for specific application including d.c. - Part 11: Requirements and tests for SPDs in photovoltaic applications

This European Standard defines the requirements and tests for SPDs intended to be installed on the d.c. side of photovoltaic installations to protect against induced and direct lightning effects. These devices are connected to d.c. power circuits of photovoltaic generators, rated up to 1 500 V. It takes into account that photovoltaic generators: • behave like current generators, • that their nominal current depends on the light intensity, • that their short-circuit current is almost equal to the nominal current, • are connected in series and/or parallel combinations leading to a great variety of voltages, currents and powers from a few hundreds of W (in residential installations) to several MW (photovoltaic fields). The very specific electrical parameters of PV installations on the d.c. side require specific test requirements for SPDs. SPDs with separate input and output terminal(s) that contain a specific series impedance between these terminal(s) (so called two port SPDs according to EN 61643-11) are currently not sufficiently covered by the requirements of this standard and require additional consideration. NOTE In general SPDs for PV applications do not contain a specific series impedance between the input/output terminals due to power efficiency considerations. SPDs complying with this standard are exclusively dedicated to be installed on the d.c. side of photovoltaic generators. PV installation including batteries and other d.c. applications are not taken into account and additional requirements and tests may be necessary for such applications. SPDs for which the manufacturers declares short circuit mode overload behaviour, shall require specific measures to ensure that such devices will not endanger the operator during maintenance and replacement due to possible d.c. arcing.

Nizkonapetostne naprave za zaščito pred prenapetostnimi udari - Naprave za zaščito pred prenapetostnimi udari za specifične aplikacije, vključno z enosmernimi - 11. del: Zahteve in preskusi za SPD v fotovoltaičnih aplikacijah

Ta evropski standard določa zahteve in preskuse za naprave za zaščito pred prenapetostnimi udari (SPD), namenjene za namestitev na enosmerno stran fotovoltaičnih inštalacij za zaščito pred posrednimi in neposrednimi učinki strele. Te naprave so povezane z enosmernimi napajalnimi tokokrogi fotovoltaičnih generatorjev z napetostjo do 1500 V. Standard upošteva, da za fotovoltaične generatorje velja:
• delujejo kot generatorji toka,
• njihov nazivni tok je odvisen od intenzivnosti svetlobe,
• njihov kratkostični tok je skoraj enak nazivnemu toku,
• povezani so v serijah in/ali vzporednih kombinacijah, s katerimi nastane velika raznolikost napetosti, tokov in moči, tj. od nekaj sto W (v stanovanjskih inštalacijah) do več MW (fotovoltaična polja). Zelo specifični električni parametri fotovoltaičnih inštalacij na enosmerni strani zahtevajo specifične preskusne zahteve za naprave za zaščito pred prenapetostnimi udari. Naprav za zaščito pred prenapetostnimi udari z ločenimi vhodnimi in izhodnimi terminali, ki vsebujejo posebno vzdolžno impedanco med temi terminali (v skladu s standardom EN 61643-11 t. i. naprava za zaščito pred prenapetostnimi udari z dvoje vrati), zahteve tega standarda trenutno ne zajemajo dovolj, pri čemer jih je treba dodatno obravnavati. OPOMBA Na splošno naprave za zaščito pred prenapetostnimi udari za fotovoltaične aplikacije ne vsebujejo specifične vzdolžne impedance med vhodnimi/izhodnimi terminali zaradi zadržkov v zvezi z električno učinkovitostjo. Naprave za zaščito pred prenapetostnimi udari, ki so v skladu s tem standardom, so namenjene izključno za namestitev na enosmerno stran fotovoltaičnih generatorjev. Fotovoltaične inštalacije, ki vključujejo akumulatorje in druge enosmerne aplikacije, niso upoštevane, pri čemer so za takšne uporabe morda potrebne dodatne zahteve in preskusi. Naprave za zaščito pred prenapetostnimi udari, za katere proizvajalec navaja preobremenitev kratkostičnega načina, zahtevajo posebne ukrepe za zagotovitev, da takšne naprave ne ogrožajo upravljavca med vzdrževanjem in zamenjavo zaradi morebitnega enosmernega iskrenja.
