Amakuru y'ibicuruzwa

HD11N Guhindura icyuma Yerekana ikintu gikomeye muri sisitemu yamashanyarazi ya kijyambere (PV), yagenewe byumwihariko kubikorwa byizewe kandi byizewe mubikorwa byingufu zishobora gukoreshwa. Nkigikoresho cyabugenewe cyo guhagarika, iki cyuma gihindura ubushobozi bwo kwigunga neza mugihe hubahirijwe ibisabwa bikenewe kugirango DC na AC bigabanuke mumashanyarazi yizuba. Ubwubatsi bwayo bwibanda ku kuramba n’umutekano, bigatuma bikwiranye ninganda zitandukanye za PV nubucuruzi.

MCB Guhindura wenyine, cyane cyane urukurikirane rwa BYG1-125, nibintu byingenzi bya sisitemu yo gukwirakwiza ingufu zigezweho. Yashizweho kugirango itange uruziga rwizewe kandi rusobanutse, igikoresho gikomatanya kurinda icyuma cyumuzunguruko gito (MCB) hamwe nubushobozi bwo guhagarika isuku bwakato. Nka ngingo ikomeye yo kugenzura, irashobora guhagarika burundu amashanyarazi kumugezi wo hasi mugihe cyo kubungabunga, gusana cyangwa guhagarika byihutirwa, bityo umutekano w abakozi nibikoresho. Kubaka kwayo gukomeye hamwe nubuziranenge bwamashanyarazi bituma iba ikintu cyingirakamaro mubucuruzi nubucuruzi.

Urukurikirane rwa BYW1 rugaragaza intambwe ikomeye mu buhanga bwo kurinda amashanyarazi. Yashizweho na gride ya AC 50Hz, ubu bwenge bwogukwirakwiza ikirere cyumuyaga (ACB) bugera kuri 690V kandi bufite ubushobozi bwo gukora kugeza kuri 6300A. Nka nkingi yifatizo yo gukwirakwiza amashanyarazi meza, irinda byimazeyo ibikorwa remezo bikomeye mu nganda zinganda, inganda zubucuruzi, hamwe n’ibikoresho binini bituruka ku mashanyarazi akomeye.

Ibikoresho by'amashanyarazi bigezweho bisaba ibisubizo byumutekano byuzuye, kandi BY02L-63 ikurikirana itanga uburinzi bwingenzi. Uku Kumenagura Ibisigisigi Byubu (RCBO) bikomatanya birenze urugero, bigufi, hamwe nubutaka bwo kumeneka kwisi mubikoresho bimwe byoroheje. Ikigereranyo cya 3kA yameneka, irinda sisitemu zo guturamo, iz'ubucuruzi, n’inganda kwirinda ingaruka ziterwa n’amashanyarazi n’ingaruka ziterwa n’umuriro ziterwa n’amakosa. Hamwe no kwiyumvamo imigezi isigaye iteye akaga (mubisanzwe 30mA), ihita ihagarika imirongo mugihe habaye ubusumbane bwangiza ubuzima, butanga uburinzi bwibanze bwabakozi.

Urukurikirane rwa BY08DC 1 + 2-12.5 rugaragaza iterambere rikomeye mukurinda sisitemu ya Photovoltaque. Iki gikoresho cyihariye cyo gukingira Dc Surge (SPD) gitanga ubwirinzi bwa T1 + T2 bwokwirinda cyane cyane bwakorewe kumasanduku yizuba hamwe na inverter. Yifashishije tekinoroji ya oxyde oxyde varistor (MOV), itanga uburyo bukomeye bwo kwirinda inkuba (10 / 350μs) no guhinduranya (8 / 20μs). Hamwe nubushobozi bwo gusohora buri hagati ya 20kA na 40kA kuri pole, iyi SPD iremeza ko ibikoresho bikomeye bya DC bikomeza gukingirwa kwangiza ingufu za voltage mubuzima bwayo bwose.

Urukurikirane rwa BY04L-63 rugaragaza iterambere rikomeye mumutekano wamashanyarazi, uhuza ibikorwa byingenzi byo kurinda igikoresho kimwe. Iyi miyoboro isigaye yumuzunguruko (RCBO) itanga uburinzi bwuzuye kubintu bitatu byingenzi: umuvuduko ukabije, umuyoboro mugufi, hamwe ningaruka zisigaye zangiza (isi yamenetse). Yagenewe kwizerwa, irinda neza abakozi bombi guhitanwa n’amashanyarazi no kwishyiriraho ingaruka ziterwa n’umuriro uterwa n’amakosa y’umuriro cyangwa amashanyarazi arenze urugero, bigatuma biba shingiro rya sisitemu y’amashanyarazi igezweho.
