Kubikorwa byose byizuba, ukeneye umugozi wizuba kugirango uhuze ibyuma byizuba.Imirasire y'izuba myinshi irimo insinga z'ibanze, ariko rimwe na rimwe ugomba kugura insinga wigenga.Aka gatabo kazasobanura ibyibanze byinsinga zizuba mugihe ushimangira akamaro kinsinga kuri sisitemu yizuba ikora.

Umugozi w'izuba, rimwe na rimwe uzwi nka 'PV Wire' cyangwa 'PV Cable' niwo mugozi w'ingenzi wa sisitemu y'izuba iyo ari yo yose.Imirasire y'izuba itanga amashanyarazi agomba kwimurirwa ahandi - aha niho haza insinga z'izuba. Itandukaniro rinini mubijyanye n'ubunini ni hagati y'insinga z'izuba 4mm na kabili y'izuba 6mm.Aka gatabo kazagereranya ibiciro byinsinga nuburyo bwo kubara ingano ukeneye kugirango izuba ryizuba.

Intangiriro Kuri Imirasire y'izuba

Kumva uburyoinsinga z'izubaimikorere, tugomba kugera kumikorere yibanze ya kabili: Umugozi.Nubwo abantu bakeka ko insinga ninsinga aribintu bimwe, aya magambo aratandukanye rwose.Imirasire y'izuba ni ibice bimwe, bizwi nka 'kiyobora'.Imirasire y'izuba ni amatsinda y'insinga / abayobora bateraniye hamwe.

Mu byingenzi, iyo uguze umugozi wizuba uba uguze umugozi ufite insinga nyinshi zahambirijwe hamwe kugirango ubashe gukora umugozi.Imirasire y'izuba irashobora kugira insinga nke nka 2 hamwe ninsinga nyinshi, bitewe nubunini.Birahendutse rwose kandi bigurishwa n'amaguru.Ikigereranyo cyizuba cyizuba ni $ 100 kuri 300 ft.

Nigute insinga z'izuba zikora?

Ubusanzwe insinga yizuba ikozwe mubikoresho bishobora gutwara amashanyarazi nkumuringa.Umuringa ni ibikoresho bizwi cyane ku nsinga z'izuba, kandi rimwe na rimwe insinga zikoze muri aluminium.Buri cyuma cyizuba numuyoboro umwe ukora wenyine.Kugirango wongere imikorere ya kabili, insinga nyinshi ziteranijwe hamwe.

Umugozi wizuba urashobora gukomera (kugaragara) cyangwa gukingirwa nicyo bita 'jacket' (urwego rukingira rutagaragara).Kubijyanye n'ubwoko bw'insinga, hariho insinga imwe cyangwa ikomeye.Byombi bikoreshwa mugukoresha izuba.Nyamara, insinga zahagaritswe nizo zikunze kugaragara cyane kuko zigizwe nudusimba duto duto twinshi twahujwe hamwe kugirango tugire intangiriro yinsinga.Insinga imwe yunuka iraboneka gusa mubipimo bito.

Intsinga zitsindagiye nizo nsinga zisanzwe kuri insinga za PV kuko zitanga urwego rwo hejuru rwumutekano.Ibi birinda uburinganire bwimiterere yinsinga iyo bigeze kumuvuduko ukomoka kunyeganyega nizindi ngendo.Kurugero, niba inyoni zinyeganyeza insinga cyangwa zigatangira kuzinya hejuru yinzu hejuru yizuba, ukeneye ubundi bwirinzi kugirango amashanyarazi akomeze kugenda.

Umugozi wa PV ni iki?

Imirasire y'izuba ni insinga nini zigizwe ninsinga nyinshi munsi ya 'jacket' ikingira.Ukurikije izuba, uzakenera umugozi utandukanye.Birashoboka kugura umugozi wizuba wa 4mm cyangwa umugozi wizuba wa 6mm uzaba mwinshi kandi ugatanga imiyoboro ya voltage ndende.Hariho kandi itandukaniro rito muburyo bwa kabili ya PV nkinsinga za DC ninsinga za AC.

Uburyo bwo Kuringaniza Imirasire y'izuba: Intangiriro

Ibikurikira nintangiriro yo gukosora ingano na terminologiya.Gutangirira hamwe, ingano ikunze gukoreshwa ninsinga zizuba ni "AWG" cyangwa 'American Wire Gauge'.Niba ufite AWG yo hasi, ibi bivuze ko itwikiriye igice kinini cyambukiranya igice bityo ikagira umuvuduko muke wa voltage.Uruganda rukora imirasire y'izuba rugiye kuguha imbonerahamwe yerekana uburyo ushobora guhuza imiyoboro ya DC / AC.Ugiye gukenera amakuru yerekana icyerekezo ntarengwa cyemewe kubice byambukiranya igice cyizuba ryizuba, umuvuduko wa voltage, na DVI.

Ingano yumurongo wizuba ikoreshwa ni ngombwa.Ingano ya kabili irashobora kugira ingaruka kumikorere yizuba ryose.Niba uguze insinga ntoya kuruta iyasabwe nuwagukoresheje izuba, urashobora guhura nigitonyanga gikomeye mumashanyarazi hejuru yinsinga amaherezo bikaviramo gutakaza amashanyarazi.Ikirenzeho, niba ufite insinga zidafite umurongo ibi birashobora gutuma imbaraga ziyongera kumuriro.Niba umuriro uturutse ahantu nko hejuru y'inzu, birashobora gukwirakwira vuba aha.

Uburyo insinga za PV zingana: AWG Ibisobanuro

Kugaragaza akamaro k'ubunini bwa PV, tekereza umugozi nka hose itwara amazi.Niba ufite diameter nini kuri hose, amazi azatemba byoroshye kandi ntabwo azashyira imbaraga.Ariko, niba ufite shitingi ntoya noneho uzabona guhangana kuko amazi adashobora gutemba neza.Uburebure nabwo bugira ingaruka - niba ufite hose, amazi atemba vuba.Niba ufite hose nini, ukeneye umuvuduko ukwiye cyangwa amazi atemba.Insinga zose z'amashanyarazi zikora muburyo bumwe.Niba ufite umugozi wa PV utari munini bihagije kugirango ushyigikire imirasire y'izuba, guhangana birashobora gutuma watts nkeya yimurwa no guhagarika uruziga.

Umugozi wa PV ufite ubunini ukoresheje American Wire Gauges kugirango ugereranye igipimo cyapimwe.Niba ufite insinga ifite numero ntoya (AWG), uzagira imbaraga nke kandi umuyaga uva mumirasire y'izuba uzagera neza.Intsinga zitandukanye za PV zifite ubunini butandukanye, kandi ibi birashobora kugira ingaruka kubiciro bya kabili.Ingano ya buri gipimo ifite igipimo cyayo cya AMP nicyo kinini ntarengwa cya AMP gishobora kunyura mumugozi neza.

Buri nsinga irashobora kwakira gusa umubare runaka wa amperage na voltage.Mugusesengura imbonerahamwe yinsinga, ugomba gushobora kumenya ingano ikwiye kuri sisitemu yizuba (niba ibi bitashyizwe mubitabo).Uzakenera insinga zitandukanye kugirango uhuze imirasire yizuba na inverter nkuru, hanyuma inverter kuri bateri, bateri kuri banki ya bateri, na / cyangwa inverteri kuri gride yamashanyarazi yinzu.Ibikurikira nuburyo bwateguwe bwo kugufasha kubara:

1) Gereranya VDI (Umuvuduko wa Voltage)

Kubara VDI ya sisitemu yizuba, uzakenera amakuru akurikira (yatanzwe nuwagukoreye):

· Amperage yose (amashanyarazi).

· Uburebure bwa kabili muburyo bumwe (bupimirwa mubirenge).

· Ijanisha rya voltage.

Koresha iyi formula kugirango ugereranye VDI:

· Amperage x Ibirenge /% bya voltage igabanuka.

2) Menya ingano ishingiye kuri VDI

Kugirango ubare ingano ukeneye kuri buri kabili ya sisitemu, ukeneye VDI.Imbonerahamwe ikurikira izagufasha kumenya ingano ukeneye kubisabwa:

Umuvuduko Wumuvuduko wa Gauge

VDI GAUGE

1 = # 16

2 = # 14

3 = # 12

5 = # 10

8 = # 8

12 = # 6

20 = # 4

34 = # 2

49 = # 1/0

62 = # 2/0

78 = # 3/0

99 = # 4/0

Urugero: Niba ufite AMP 10, metero 100 zintera, ikibaho cya 24V, nigihombo cya 2% urangiza ufite ishusho ya 20.83.Ibi bivuze umugozi ukeneye ni umugozi wa 4 AWG.

PV Imirasire y'izuba Ingano & Ubwoko

Hariho ubwoko bubiri bw'insinga z'izuba: insinga za AC n'insinga za DC.Umugozi wa DC ninsinga zingenzi cyane kuko amashanyarazi dukoresha mumirasire y'izuba kandi dukoresha murugo ni amashanyarazi ya DC.Imirasire y'izuba myinshi izana insinga za DC zishobora guhuzwa nu muhuza uhagije.Imirasire y'izuba ya DC irashobora kandi kugurwa neza kuri CW Cable.Ingano izwi cyane kuri insinga za DC ni 2.5mm,4mm, na6mminsinga.

Ukurikije ubunini bwizuba ryumuriro n amashanyarazi yatanzwe, urashobora gukenera umugozi munini cyangwa muto.Umubare munini w'izuba muri Amerika ukoresha umugozi wa 4mm PV.Kugirango ushyireho insinga neza, ugomba guhuza insinga zitari nziza kandi nziza uhereye kumurongo uri mumasanduku nyamukuru ahuza itangwa nuwakoze izuba.Mubyukuri insinga zose za DC zikoreshwa ahantu hanze nko hejuru yinzu cyangwa ahandi hantu hashyizwe imirasire yizuba.Kwirinda impanuka, insinga nziza za PV ziratandukanye.

Nigute ushobora guhuza insinga z'izuba?

Hariho insinga 2 zingenzi zikenewe kugirango uhuze izuba.Ubwa mbere, ukeneye umugozi utukura ubusanzwe ni umugozi mwiza wo gutwara amashanyarazi na kabili yubururu bikaba bibi.Izi nsinga zihuza agasanduku nyamukuru ka generator ya sisitemu yizuba hamwe nizuba ryizuba.Intsinga ntoya imwe-imwe irashobora kuba ingirakamaro mugukwirakwiza ingufu mugihe zipfunyitse.

Imiyoboro ya AC nayo ikoreshwa muri sisitemu yizuba, ariko ntibikunze kubaho.Intsinga nyinshi za AC zikoreshwa muguhuza imirasire yizuba nyamukuru hamwe numuyoboro wamashanyarazi murugo.Imirasire y'izuba ikoresha insinga 5-zifite insinga za AC zifite insinga 3 zicyiciro gitwara umuyaga, insinga 1 kugirango umuyaga utaba kure yigikoresho, hamwe ninsinga 1 yo guhaguruka / umutekano uhuza izuba nubutaka.

Ukurikije ubunini bwizuba ryizuba, birashobora gusaba gusa insinga 3-yibanze.Ariko, ibi ntabwo bigeze bihurira hamwe kuko leta zitandukanye zikoresha amabwiriza atandukanye agomba gukurikizwa nababigize umwuga bashiraho insinga.
