Nowadays, Photovoltaic systems (PV System) range from small, rooftop-mounted or building-integrated systems with capacities from a few to several tens of kilowatts, to large utility-scale power stations of hundreds of megawatts, and in the meanwhile the potential impact of lightning events increases with PV system size. Where lighting occurrences are frequent, unprotected PV systems can suffer repeated and significant damage to key components. This results in substantial repair and replacement costs, system downtime and the loss of revenue.
PROSURGE has developed a high performance but low cost solution for the industry of PV/DC power electronics, a surge protection module PVTMOV O'lchamni optimallashtirish va bo'sh joy samaradorligi, chaqmoq hodisalarining potentsial ta'sirini kamaytirish uchun bosilgan elektron platalarga (PCB) va qurilmaning ichidagi sezgir elektron elementga yaqin joylashadi.
DC/PV quyosh uchun tenglikni o'rnatish SPD moduli
PVTMOV - bu PCB lehimli modul, ayniqsa invertorlar, PV birlashtiruvchi qutilar, konvertorlar uchun dastur va boshqalar.
PROSURGE® PVTMOV yuqori energiyali metall oksidi varistoridan (MOV) foydalanadi va noto'g'ri oqim yoki g'ayritabiiy kuchlanish sodir bo'lganda xavfsiz uzilishni ta'minlaydigan patentlangan termal himoya va yoyni o'chirish texnologiyasi bilan qurilgan. Ma'lumki, metall oksidi varistori (MOV) kuchlanish va oqimni cheklash, shuningdek energiyani yutish uchun ideal komponent hisoblanadi, ammo MOV termal qochib ketishi va doimiy g'ayritabiiy kuchlanish (TOV) yoki qisqa tutashuvga olib kelishi mumkin. foydalanish muddati tugashi, bu yong'in xavfi va mijozga katta yo'qotishlarga olib kelishi mumkin. Prosurge® kuchlanishdan himoyalanish modullari xavfsizlik ko'rsatkichlarini har tomonlama yaxshilagan va patentlangan texnologiya tufayli a'lo darajadagi nosozliklar va o'zini o'zi himoyalangan himoya vositalari ekanligi isbotlangan.
SPD Module xususiyatlari
- IEC/EN 2-61643 boʻyicha TUV sertifikati II/T 31 PV SPD
- UL tomonidan tan olingan UL 1 1449 bo'yicha 5ca turdagi kuchlanishdan himoya modullari

- PCB o'rnatish dizayni va himoyalangan sezgir elektron elementga yaqin o'rnatilishi mumkin.
- Qayta oqim va to'lqin bilan lehimlash protsedurasiga mos keladi
- O'rnatish joyini tejash uchun ixcham o'lcham
- Og'ir metall oksidi varistori (MOV) tufayli 25kA 8/20 gacha bo'lgan yuqori tushirish quvvati
- Yoyni o'chirish moslamasi (Patentlangan) bilan maxsus termal ajratgich dizayni tufayli yuqori ishonchlilik, nosozlikdan xavfsiz va o'zini himoyalangan, tez termal javob va mukammal zanjirni uzish funktsiyasi.
- Keng ish harorati oralig'i (-40 ~ + 110 ℃)*
- Yuqori balandlikda ishonchli (-500m ~ + 4000m malakali)
- Nosozlikni ko'rsatish uchun suzuvchi masofaviy signalizatsiya kontakti.
