Impamvu Isesengura ryimpanuka yumuriro kuri DC Kuruhande rwa PV Amashanyarazi

Sisitemu yo kubyara ingufu za Photovoltaque iragenda yegereza ubuzima bwacu.Igishushanyo gikurikira kirerekana impanuka zimwe na zimwe za sisitemu yo kubyara amashanyarazi, bigomba gukurura cyane abakora amafoto.

Impamvu ni izi zikurikira:

1. Kumenagura Pin ya Cable ya PV na Connector ntabwo yujuje ibyangombwa

Bitewe n'ubwiza buke bw'abakozi bashinzwe ubwubatsi, cyangwa ishyaka ryubwubatsi ntabwo ryahaye amahugurwa yumwuga ababikora, kugabanuka kutujuje ibyangombwa bifotora bifotora nimpamvu nyamukuru yo guhura nabi hagati yumugozi wa PV nuhuza, ariko kandi nimwe mubyingenzi ibitera impanuka muri sisitemu yo kubyara amashanyarazi.Umugozi wa Photovoltaque numuhuza ni umuhuza woroheje, umugozi wambaye ubusa wa 1000V urashobora kugwa kumuhuza umwanya uwariwo wose hejuru yinzu, bigatera impanuka zumuriro.

Niba ushaka kumenya gahunda yo kwishyiriraho neza ya MC4 ihuza, urashobora gusoma:Nigute ushobora gukora MC4 ihuza?

2. Ikibazo cyo Guhuza PV Solar Ihuza Ibicuruzwa Bitandukanye

Ihame,PV ihuza izubayikimenyetso kimwe nicyitegererezo bigomba gukoreshwa muguhuza.Buri inverter ahanini izana numubare umwe wamafoto yerekana amashanyarazi, nyamuneka wemeze gukoresha imiyoboro ihuza kugirango ushyire.Igihe cyose yashizwemo neza, guhuza kuruhande rwa inverter muri rusange ntabwo ari ikibazo.Ariko, haracyari ikibazo kuruhande rwibigize.Bitewe nuburyo butandukanye bwibiranga amafoto yerekana amashanyarazi ku isoko, uruganda rwibigize ntabwo rwatanze imiyoboro ihuza.

Dufite ibyifuzo bitatu kuri ibi: icya mbere, gura pv paneli ihuza ikirango kimwe nizuba;Icya kabiri, gabanya umuhuza kumpera yumurongo hanyuma usimbuze umuhuza wubwoko bumwe nubwoko;Icya gatatu, niba ugomba gukoresha PV ihuza ibirango bitandukanye, urashobora guca umurongo wabyo hanyuma ukabishyiramo numuhuza waguze.Niba umuhuza ucomeka neza, kora igikorwa cyo guhuzagurika.Niba hari umwuka uva, iki gice cyibicuruzwa ntigishobora gukoreshwa hamwe.Noneho koresha multimeter kugirango urebe niba imiyoboro ihuza imiyoboro ihujwe.Ntishobora gukoreshwa mugihe uhagaritswe.Bitewe nikibazo cyo guhuza, guhura nabi cyangwa kumeneka kwamazi nimwe mubitera impanuka zumuriro.

Kuki bidasabwa ko abahuza ibirango bitandukanye bakoreshwa hamwe?, impamvu nyamukuru nuko abakora ibicuruzwa bitandukanye bashobora kuvuga ko ibicuruzwa byabo bishobora guhuzwa na MC4 ya Stäubli.Nubwo ibi aribyo, kubera ikibazo cyo kwihanganira ibyiza kandi bibi, nta cyemeza ko ibicuruzwa byabatari Stäubli bishobora guhuzwa.Niba ibirango bibiri bitandukanye byamafoto yerekana amafoto afite raporo yikizamini cyo guhuza ibitsina, urashobora kuyikoresha ufite ikizere.

3. Imirongo imwe cyangwa myinshi Yumuzingi Ibyiza nibibi bya Pole ya PV irahujwe

Mubisanzwe, inverter igizwe na MPPT nyinshi.Kugirango ugabanye ibiciro, ntibishoboka gutwara MPPT imwe kuri buri muzunguruko.Kubwibyo, munsi ya MPPT, ibice 2 ~ 3 byamafoto ya fotokoltaque yinjiza mubisanzwe.Inverter ivuga ko ifite imikorere ihuza ibikorwa irashobora kwemeza gusa kurinda imiyoboro ihindagurika mugihe umuyoboro umwe cyangwa benshi ba MPPT bahujwe mugihe kimwe.Niba munsi ya MPP imwe, igice cyayo cyahinduwe, bihwanye no guhuza inkingi nziza kandi mbi yibipaki bibiri bihabanye rwose na voltage ya 1000V.Ibibyara umusaruro muriki gihe bizaba bitagira umupaka, ntaho bihurira na gride yo gukora inverter kuruhande cyangwa impanuka yumuriro wa inverter.

Urufunguzo rwo gukemura ibibazo nkibi cyangwa kubaka ibibazo bisanzwe, nyuma yo kurangiza gushyira ibice, ukurikije ibishushanyo mbonera byumurongo wa DC, buri cyuma gitukura PV DC itukura byose biranga ibyiza, kugirango bikomeze kandi bimenyekane neza.Dore interuro irashobora gukoreshwa nkamahugurwa: "ibice byiza, umurongo wo kwagura ni kwagura gusa umurongo mwiza, ugomba kuba mwiza".Kubyerekeranye no gushiraho ikimenyetso cyo kwagura module, menya neza ko imirongo itandukanye kumpera ya inverter itigera yitiranya.

Ibibazo nkibi ntibishobora kubaho mugihe gito, ariko niba ari ibihe by'imvura, kandi umuhuza wa kabili ya PV uri ahantu huzuye imvura.Umuyagankuba mwinshi utaziguye uzakora umugozi hamwe nubutaka, bikaviramo impanuka yamashanyarazi.Iki kibazo nuguhitamo umuhuza, kandi hafi ya ntamuntu numwe uzitondera ikibazo nyacyo kitagira amazi cyumuhuza.Amazi adakoreshwa na IP65 na IP67 ya fotora ya fotora ni ibisabwa, kandi bigomba guhuzwa numuyoboro wamafoto yubunini bungana.Kurugero, MC4 isanzwe ya Stäubli ifite moderi eshatu zubunini butandukanye: 5 ~ 6MM, 5.5 ~ 7.4MM, 5.9 ~ 8.8MM.Niba diameter yo hanze ya kabili ari 5.5, umuhuza wa Stäubli uzenguruka ku isoko ntabwo ari ikibazo kinini, ariko Niba umuntu ahisemo MC4 ya 5.9-8.8MM, ibyago byihishe byimpanuka yamenetse bizahoraho.Ku kibazo cyimbere ya O-impeta, umuhuza rusange wamafoto yumuriro hamwe nababikora ubwabo bahujwe nibibazo bike bitagira amazi, ariko utabanje kwipimisha nabandi bakora kugirango bajyane no gukoresha ibibazo bitarinda amazi birashoboka cyane.

5. Umuyoboro wa PV DC cyangwa insinga za PV ziri mubidukikije bitose igihe kirekire

Hafi ya buri wese atekereza ko ibice bitwara insinga za fotokoltaque hamwe nu muhuza wifoto bifotora hamwe nibindi bikoresho, kandi PV ihuza bivugwa ko idafite amazi.Mubyukuri, birinda amazi ntibisobanura ko bishobora kubikwa mumazi igihe kirekire.Ihuza izuba rya IP68 risobanura ko umuhuza wamafoto wabanje gushyirwaho ufite insinga winjijwe mumazi, kandi hejuru ni metero 0.15 ~ 1 uvuye hejuru y’amazi muminota 30 bitagize ingaruka kumikorere.Ariko tuvuge iki niba yararohamye mumazi muminsi 10 cyangwa irenga?

Umugozi wa PV kuri ubu ku isoko harimo PV1-F, H1Z2Z2-K, 62930IEC131 nawo urashobora kuba igihe gito, nko kumena amazi magufi, cyangwa no kwegeranya amazi, ariko igihe cyamazi ntigishobora kuba kirekire, kugirango gitemba vuba kandi guhumeka byumye.Umugozi wumuriro wa Photovoltaque kubera ko uruhande rwubwubatsi rwumugozi wa Photovoltaque rwashyinguwe ahantu h'igishanga, hamwe n’amazi maremare yatose, umugozi wa Photovoltaque mumazi yinjira mumazi yatewe no gusenyuka kwaka arc.Muri uku gushimangira bidasanzwe, gushyira insinga ya Photovoltaque ikoresheje umuyoboro birashoboka cyane ko umuriro, impamvu ni ukwirundanya kwigihe kirekire mumazi mumiyoboro ya PVC.Niba ukeneye kuryamaho umuyoboro wa PVC, ibuka kureka umunwa wa PVC ukamanuka, cyangwa mumazi yo hasi cyane yumuyoboro wa PVC kugirango utere umwobo kugirango wirinde amazi.

Kugeza ubu, insinga y’amazi adafite amazi, amashanyarazi yatoranijwe mu mahanga AD8 y’amazi adakoreshwa n’amazi, bamwe mu bakora uruganda bakoresha mu kuzenguruka kuri bariyeri y’amazi, hiyongereyeho uburyo bwa aluminium-plastiki bukomatanyirijwe hamwe.

Hanyuma, insinga zisanzwe zifotora ntizishobora gushirwa mumazi igihe kinini, kandi ntizishobora gukoreshwa mubushyuhe bwinshi nubushuhe bwinshi mugihe kirekire.Guhera aha, abubatsi barashobora gukora imirimo isanzwe ifatanije nubwubatsi nyirizina.

6. Uruhu rwa PV Cable Uruhu rurashushanyije cyangwa rwunamye cyane mugihe cyo Gushyira

Gushushanya uruhu rwa kabili bizagabanya cyane imikorere yimikorere no guhangana nikirere.Mu bwubatsi, kugorora insinga birasanzwe.Igipimo giteganya ko diameter ntarengwa yo kugunama igomba kuba irenze inshuro 4 umurambararo wa kabili, naho diameter ya kabili ya kwadarato 4 ya kare ni 6MM.Kubwibyo, diameter ya arc kumugongo ntigomba kuba munsi ya 24MM, ihwanye na nyina Ingano yumuzingi ikozwe nurutoki nintoki.

7. Muri Grid-Ihuza na Leta, Gucomeka no Kuramo PV DC Umuhuza

Mugihe cyahujwe na gride, gucomeka no gukuramo umuhuza bizabyara arc amashanyarazi, bikaba bishoboka ko byatera impanuka.Niba arc irushijeho gutwika ibintu byaka, bizatera impanuka ikomeye.Noneho rero, menya neza ko ukora neza nyuma yo guhagarika amashanyarazi ya AC, kandi sisitemu ya Photovoltaque igomba guhora yazimye kugirango umutekano wigihe kirekire.

8. Ingingo iyo ari yo yose muri PV Ikurikiranyabihe irashinguwe cyangwa ikora inzira hamwe nikiraro

Ibihe bitera ingingo iyo ari yo yose mu mugozi wa PV guhagarara cyangwa gukora inzira hamwe nikiraro biragoye cyane, harimo gushiramo igihe kirekire insinga za PV twavuze haruguru, gushiraho imiyoboro ya PV kumurongo wagutse, na hejuru yinsinga zirimo gushushanywa mugihe cyo kubaka cyangwa uruhu rwumugozi rushobora kurumwa nimbeba mugihe cyo gukoresha, kandi umurabyo uzavunika, nibindi.
