1. Ubushyuhe ni iki?

Derating nigenzurwa ryigabanuka ryimbaraga za inverter.Mubikorwa bisanzwe, inverters ikora kumwanya wabo ntarengwa.Kuriyi mikorere, ikigereranyo kiri hagati ya PV voltage na PV ibisubizo byimbaraga nyinshi.Umubare ntarengwa w'amashanyarazi uhinduka buri gihe bitewe nurwego rw'izuba hamwe n'ubushyuhe bwa PV.

Kugabanuka k'ubushyuhe birinda semiconductor yunvikana muri inverter gushyuha.Ubushyuhe bwemewe bumaze kugenzurwa bumaze kugerwaho, inverter ihindura aho ikora kugirango igabanye ingufu.Imbaraga zagabanutse mu ntambwe.Mubihe bimwe bikabije, inverter izahagarara burundu.Mugihe ubushyuhe bwibintu byoroshye bigabanutse munsi yagaciro kongeye, inverter izagaruka kumwanya mwiza wo gukora.

Ibicuruzwa byose bya Renac bikora ku mbaraga zose n’umuyaga wuzuye kugeza ku bushyuhe runaka, hejuru yazo zishobora gukora hamwe n’amanota yagabanijwe kugirango birinde kwangiza ibikoresho.Iyi nyandiko ya tekinike yerekana incamake ya de-rating ya Renac inverters niki gitera ubushyuhe bukabije nibishobora gukorwa kugirango birinde.

ICYITONDERWA

Ubushyuhe bwose mubyangombwa bivuga ubushyuhe bwibidukikije.

2. De-rating properties of Renac inverters

Icyiciro kimwe

Ubwoko bwa inverter bukurikira bukora ku mbaraga zose n’umuvuduko wuzuye kugeza ku bushyuhe buri ku mbonerahamwe ikurikira, kandi bukora hamwe n’ibiciro byagabanutse kugera kuri 113 ° F / 45 ° C ukurikije ibishushanyo bikurikira.Igishushanyo gisobanura kugabanuka kwubu bijyanye nubushyuhe.Ibisohoka nyabyo ntabwo bizigera bisumba ibyateganijwe byerekanwe muri inverter datasheets, kandi birashobora kuba munsi yibyasobanuwe mubishushanyo bikurikira bitewe na moderi yihariye ya inverter kuri buri gihugu na gride.

Ibice bitatu

Ubwoko bwa inverter bukurikira bukora ku mbaraga zose n’umuyaga wuzuye kugeza ku bushyuhe buri ku mbonerahamwe ikurikira, kandi bukora hamwe n’ibiciro byagabanutse kugera kuri 113 ° F / 45 ° C, 95 ℉ / 35 ℃ cyangwa 120 ° F / 50 ° C ukurikije ku gishushanyo gikurikira.Igishushanyo gisobanura kugabanuka kwubu (imbaraga) bijyanye nubushyuhe.Ibisohoka nyabyo ntabwo bizigera bisumba ibyateganijwe byerekanwe muri inverter datasheets, kandi birashobora kuba munsi yibyasobanuwe mubishushanyo bikurikira bitewe na moderi yihariye ya inverter kuri buri gihugu na gride.

Hybrid Inverters

Ubwoko bwa inverter bukurikira bukora ku mbaraga zose n’umuvuduko wuzuye kugeza ku bushyuhe buri ku mbonerahamwe ikurikira, kandi bukora hamwe n’ibiciro byagabanutse kugera kuri 113 ° F / 45 ° C ukurikije ibishushanyo bikurikira.Igishushanyo gisobanura kugabanuka kwubu bijyanye nubushyuhe.Ibisohoka nyabyo ntabwo bizigera bisumba ibyateganijwe byerekanwe muri inverter datasheets, kandi birashobora kuba munsi yibyasobanuwe mubishushanyo bikurikira bitewe na moderi yihariye ya inverter kuri buri gihugu na gride.

3. Impamvu yo kugabanuka k'ubushyuhe

Kugabanuka k'ubushyuhe bibaho kubera impamvu zitandukanye, harimo n'ibi bikurikira:

• Inverter ntishobora gukwirakwiza ubushyuhe bitewe nuburyo bwo kwishyiriraho nabi.
• Inverter ikoreshwa mumirasire yizuba itaziguye cyangwa mubushyuhe bukabije bwibidukikije bikumira ubushyuhe buhagije.
• Inverter yashyizwe muri guverenema, mu kabati cyangwa ahandi hantu hafunze.Umwanya muto ntushobora gukonjesha inverter.
• PV array na inverter ntaho bihuriye (imbaraga za PV array ugereranije nimbaraga za inverter).
• Niba ikibanza cyo kwinjizamo inverter kiri ku butumburuke butari bwiza (urugero: ubutumburuke buri murwego rwo hejuru rwo hejuru rwo hejuru cyangwa hejuru yurugero rwinyanja, reba Igice "Data Tekinike" mubitabo bikora).Nkigisubizo, kugabanuka k'ubushyuhe birashoboka cyane ko bibaho kubera ko umwuka uba muke ku butumburuke bityo ntibishobora gukonjesha ibice.

4. Shyushya gusohora inverters

Renac inverters ifite sisitemu zo gukonjesha zijyanye n'imbaraga zazo.Cool inverters ikwirakwiza ubushyuhe mukirere binyuze mumashanyarazi hamwe nabafana.

Igikoresho kimaze kubyara ubushyuhe burenze ubw'uruzitiro rwacyo gishobora gutandukana, umuyaga w'imbere urafungura (umuyaga urafungura iyo ubushyuhe bwa sink ubushyuhe bugera kuri 70 ℃) hanyuma bugakurura umwuka binyuze mumiyoboro ikonje yikigo.Umufana agenzurwa nihuta: ihinduka byihuse uko ubushyuhe buzamuka.Ibyiza byo gukonjesha nuko inverter ishobora gukomeza kugaburira imbaraga zayo ntarengwa uko ubushyuhe buzamuka.Inverter ntisuzumwa kugeza sisitemu yo gukonjesha igeze kumipaka yubushobozi bwayo.

Urashobora kwirinda kugabanuka kwubushyuhe ushyiramo inverter kuburyo ubushyuhe bwakwirakwijwe bihagije:

• Shyiramo inverter ahantu heza(urugero munsi yo munsi aho kuba attike), ubushyuhe bwibidukikije hamwe nubushuhe bugereranije bigomba kuba byujuje ibisabwa bikurikira.

• Ntugashyire inverter mu kabari, mu kabati cyangwa ahandi hantu hafunze, hagomba gutangwa umwuka uhagije kugira ngo ugabanye ubushyuhe butangwa n’igice.
• Ntugaragaze inverter kugirango yerekane imirasire y'izuba.Niba ushyizeho inverter hanze, shyira mugicucu cyangwa ushyire hejuru yinzu.

• Komeza byibuze byemewe kuva muri inverter zegeranye cyangwa ibindi bintu, nkuko bigaragara mubitabo byubushakashatsi.Ongera neza niba ubushyuhe bwo hejuru bushobora kugaragara ahabigenewe.

• Mugihe ushyiramo inverteri nyinshi, bika neza bihagije kugirango uhindure umwanya uhagije wo gukwirakwiza ubushyuhe.

5. Umwanzuro

Inverteri ya Renac ifite sisitemu yo gukonjesha ijyanye nimbaraga zayo nigishushanyo cyayo, kugabanya ubushyuhe nta ngaruka mbi bigira kuri inverter, ariko urashobora kwirinda kugabanuka kwubushyuhe ushyira inverter muburyo bukwiye.
