Ni iki gikwiye gusuzumwa mbere yo kugura PV DC Guhagarika Guhindura?

Mugushiraho PV ,.DC guhagarikani nkumufuka windege mumodoka.IEC 60364-7-712 isanzwe isaba gukoresha PV DC guhagarika imiyoboro hagati ya PV array na inverter.Guhindura DC guhindagura ibintu byahinduwe byumwihariko kugirango uhagarike inverteri ya DC / AC kuva imirasire yizuba.Dutanga PV guhagarika imiyoboro ya voltage kugeza 1500 V DC.Barashobora gukoreshwa mugushiraho ingingo zigenga zigenga nkuko bisabwa na VDE 6012, kurugero, kugirango bemererwe gutandukana neza inverter zifite inenge.Byose DC ihindura disikuru ihindura inkingi ebyiri kandi irakwiriye kuri sisitemu yacukuwe.

Amazu ya PV ahagarika yiteguye kwishyiriraho kandi atanga amashanyarazi ya 30 A kuri 1000 V / 1500 V DC.Kuboneka mumirongo ibiri na ine kimwe nuburyo bubiri busanzwe bwo guhuza kubwihuza.MC4 cyangwa metric kabel gland ituma habaho guhuza neza muburyo butandukanye bwa sisitemu.DC ihagarika ibice bya enterineti ifite urwego rwo kurinda IP66 bityo ikaba ikwiranye no kwishyiriraho hanze.Igikorwa cyo gufunga gitanga uburinzi mugihe cya serivisi no kubungabunga.Ikintu cyindishyi zingutu zibuza kondegene gukusanya bityo bikarinda kunanirwa kubera inkuba.

Ni iki gikwiye gusuzumwa mbere yo kugura PV Guhagarika?

1. Ni ubuhe bwoko ukeneye?

Ugomba gusuzuma ubwoko bwa PV guhagarika ibintu bisabwa, kurugero kugirango wumve imbaraga zawe zisabwa.Slocable ifite imiyoboro ihindura kuva kuri DC 1000V kugeza 1500V.Niba ushaka igisubizo cyihariye, turashobora kandi gutanga amashanyarazi ya PV ya 600V, 800V, 1000V, 1200V cyangwa 1500V.

2. Umuvuduko nubu

Niba ushaka kwinjizamo DC itandukanya, ugomba guhuza imikoranire yayo kugirango umenye neza ko ishobora kwakira ingufu zanyujijwe muri gride yayo.

Niba ukeneye imiyoboro ihanitse, uzakenera guhuza byinshi kugirango ubashyigikire kugirango wirinde ubushyuhe bukabije bwa sisitemu y'amashanyarazi.Slocable PV itandukanya ibintu byahinduwe kuva kuri 1000V, 1200V kugeza 1500 kandi byapimwe kuri 32A na 55A.

3. Icyemezo cya IEC na AS

Ikindi ugomba gusuzuma ni ukumenya ibyemezo bya IEC na AS.Niba uruganda rwa DC rwihagarika rufite ibyemezo, bivuze ko isosiyete ikurikiza amabwiriza mpuzamahanga mugihe ikora PV DC ihagarika ibicuruzwa.

Kurugero, mugice cya mbere cya EIC 60204-1: 2016, uwabikoze arasabwa gutanga intoki zikoresha intoki zikoresha intoki kuri buri soko rikuru ryamashanyarazi rishyirwaho hamwe nibipimo byihariye.

4. Uburyo bwo kwishyiriraho

Uzakenera kandi gutekereza kumwanya watoranijwe kugirango ushyireho DC uhagarike hamwe nuburyo bwo kwishyiriraho bukwiranye na porogaramu yawe.Imiterere isanzwe ni imyobo ine yubatswe, yubatswe muburyo bwa kare ifite imyobo ine ya buri mfuruka.Ubu buryo nibyiza niba ugambiriye gushiraho icyerekezo hejuru, kuko cyemerera guhinduka kuba flush bishoboka.

Ibiranga Slocable PV DC guhagarika switch:

1. Icyuma cyizewe cyane cyumubano hamwe nicyumba kirekire cyo gukonjesha cyemeza ko umutekano wa DC utandukanijwe neza.
2. Ongera umutekano hamwe na Slocable yemewe na "Security Lock".
3. Slocable PV itandukanya ibice bya seriveri iraboneka muri verisiyo ya 2 kugeza 8 ya pole no muburyo butandukanye bwo gushiraho no gukora iboneza rya porogaramu nyinshi za OEM cyangwa imirima yo kwishyiriraho.

Izi PV zapimwe nabagenzuzi kandi ni UL508i, TUV (60947-1 & 60947-3), CE na CCC byemewe.

Slocable itanga kandi ibindi bikoresho byizuba bya PV, harimo umuhuza wa Solar MC4, abafite fuse ya MC4, udusanduku twa fotokoltaque hamwe nabashinzwe kurinda DC.
