Imirasire y'izuba ya Solar: Ibice by'ingenzi kuri buri cyerekezo cy'izuba

Hejuru - ifoto nzizaUmugozi wa PVni agace gato ka sisitemu yizuba yagaragaje ingaruka kumikorere yubuzima bwose, umutekano na ROI. Guhitamo umugozi wa PV ukwiye - umuyobozi, insulasiyo, hamwe nabahuza - bigabanya gutakaza ingufu, birinda kunanirwa kandi bifasha kuzuza code (NEC / IEC / UL). Aka gatabo gasubiza ibibazo umunani bikunze kugaragara abaguzi, abashushanya n'abashiraho babaza, kandi bigatanga urutonde rwukuri rwo kugura.

Niki "insinga za PV" nizihe zitandukaniyehe ninsinga zisanzwe zamashanyarazi?

Umugozi wa PV ni umwe - uyobora, urumuri rwizuba - insinga zidashobora kwihanganira zakozwe muguhuza PV modules hamwe na DC kuruhande rwa sisitemu ya PV. Mubisanzwe bakoresha imashini zometseho amabuye, zomekeranye kandi zambuka - zihuza polyolefine (XLPO / XPLE) cyangwa izindi UV / ubushyuhe -. Umugozi wa PV urapimwe kubushyuhe bwo hejuru burambye, butaziguye - izuba ryinshi, hamwe nigihe kirekire cyo hanze - imitungo idakenewe muburyo busanzwe bwo kubaka. Ibipimo nkaIEC 62930naUL 4703gusobanura ibyubatswe nibizamini bya kabili ya PV.

Nibihe bipimo nimpamyabumenyi ngomba gusaba mugihe ngura umugozi wa PV?

Saba insinga zujuje ubuziranenge bwa PV hamwe n amanota ya gatatu -:

IEC 62930. urubuga.iec.ch

EN 50618. UL Ibisubizo

UL 4703. Ububiko bwa UL
Reba nanoneImirasire y'izubaraporo yikizamini, flame - gukwirakwiza / RT / UV ibisubizo byubusaza, hamwe nubugenzuzi bwabatanga. Icya gatatu - icyemezo cyishyaka kigabanya ibyago byo gutsindwa hakiri kare.

Nigute napima insinga za PV (AWG / mm²) - ni ibihe bintu bifite akamaro?

Ingano ya kabili iringaniza inzitizi eshatu: ampacity (ubushobozi bwubu), kugabanuka kwa voltage, hamwe nubukanishi / kwishyiriraho. Koresha ibininiumuyobozi asabwa na ampacity cyangwa voltage - amategeko yo guta. Ibintu byingenzi: umugozi ntarengwa (cyangwa inverter yinjiza), DC ya voltage ya sisitemu, igipimo cyubushyuhe bwa kiyobora, uburebure bwiruka (bigira ingaruka kumanuka wa voltage), hamwe nubushyuhe bwibidukikije (ampacity derating). Laboratwari zigihugu hamwe nubuyobozi bwinganda bushimangira buri gihe kugenzura ampacity na voltage igabanuka - hanyuma ukoreshe umuyoboro munini. Kuri PV yo guturamo, abayishyiraho mubisanzwe bazamura AWG imwe kugirango bagabanye kugabanuka kwa voltage (urugero, AWG 10 → AWG 8).Inama ifatika:intego ya munsi cyangwa ingana na 1.5-2% ya voltage igabanuka kumurongo muremure wa DC; kubintu bikomeye birebire, ongera usubire hejuru yubushyuhe bwo hejuru.

Ni ubuhe bushyuhe, voltage n'ibipimo by'ibidukikije nkeneye gusaba?

Ibipimo ntarengwa byemewe biterwa na code hamwe nu mushinga, ariko ibisabwa bisanzwe:

Ubushyuhe:Ikigereranyo byibuzeImpamyabumenyi 90bikomeza (insinga nyinshi za PV zapimwe dogere 90–125). UL 4703 yerekana amahitamo agera kuri dogere 150 kubwubatsi bumwe. Ububiko bwa UL

Umuvuduko:Ibipimo rusange bya DC ni600 V, 1.0 kV na 1.5 kV(hejuru - sisitemu ya voltage igenda iba rusange). Koresha umugozi washyizwe hejuru ya sisitemu ntarengwa ya DC. webstore.iec.ch +1

UV & kurwanya ikirere:Gukingira bigomba kuba urumuri rwizuba - birwanya kandi UV - bihamye hejuru yinzu, kwiruka byerekanwe hamwe nuburyo bwo gushyingura bitabaye ngombwa. Ibipimo (IEC / EN / UL) ikizamini cya UV no gusaza k'ubushyuhe

Ni kangahe uhuza (MC4 nibindi), kandi ni ibihe bibazo bitera?

Abahuza ni ubutumwa - birakomeye. Guhuza amakosa cyangwa gushyirwaho nabi nimpamvu nyamukuru itera kunanirwa kwa PV hamwe numuriro udasanzwe ariko ukomeye. Igeragezwa ryigenga hamwe na whitepaper yerekana ubuziranenge bwumuhuza, igishushanyo mbonera hamwe nakazi bikora bigira ingaruka zikomeye kubwizerwa. Koresha ibirango byemewe bihuza, ibikoresho bikwiye bya crimp, kandi ugenzure torque ninjiza. Shyira mubikorwa gahunda yo kugenzura O&M kugirango ubone ibara, gushyushya, cyangwa amazi yinjira.

Nibihe byubaka insinga nibyiza kuramba no kubungabunga bike?
