Nkibice byingenzi bigize amashanyarazi yose, inverter yizuba ikoreshwa mugutahura ibice bya DC nibikoresho bifitanye isano na gride. Mubisanzwe, ibipimo byose byamashanyarazi bishobora gutahurwa naizuba. Niba bidasanzwe bibaye, ubuzima bwibikoresho bifasha sitasiyo yamashanyarazi birashobora kugenzurwa hifashishijwe amakuru yagaruwe nizuba riva. Ibikurikira nincamake yamakuru amwe amwe hamwe nuburyo bwo kuvura amashanyarazi akomoka ku mirasire y'izuba.
Nta sano ihuza
impamvu y'ikibazo:
Bishatse kuvuga ko ingufu za AC zidahujwe cyangwa icyuma cyumuzunguruko wa AC cyaciwe, giteraizubakutabasha kumenya amashanyarazi ya AC.
Igisubizo:
1. Menya niba umuyoboro w'amashanyarazi udafite ingufu. Niba aribyo, tegereza amashanyarazi kugirango asubukure amashanyarazi.
2. Niba amashanyarazi ava mumashanyarazi aribisanzwe, koresha AC voltage intera ya multimeter kugirango umenye niba amashanyarazi ya AC asanzwe. Ubwa mbere, bapima icyuma gisohora izuba hanyuma urebe niba hari ikibazo kuruhande rusohoka rwizuba. Niba ntakibazo gihari, bivuze ko habaho guhagarara kumuzingo kuruhande rwa AC yo hanze. Ugomba kugenzura niba icyuma gihindura ikirere, icyuma gihindura icyuma, imbaraga zirenze urugero n’umurengera munsi ya voltage hamwe n’indi mikorere y’umutekano yangiritse cyangwa ikinguye.
Umuyagankuba wa AC utari kure
impamvu y'ikibazo:
Iyo amashanyarazi yamashanyarazi ahujwe nabakoresha-amashanyarazi, voltage yumwanya wo kwiyongera iziyongera. Ninini irwanya imbere ya gride ya power, niko gushimira. Iyo wegereye transformateur, ntoya irwanya umurongo, niko ihindagurika rito muri gride rizaba, kandi niko wegera impera ya gride, umurongo muremure, niko ihindagurika ryinshi rya voltage. Kubwibyo, iyoizubaihujwe na gride kure ya transformateur, imiyoboro ikora ya gride ikora izuba rihinduka ubukene cyane. Nyuma yumupaka wo hejuru wizuba ryumuriro wizuba urenze, inverter izuba izatanga amakosa ikareka gukora. Ukurikije ibisobanuro bya tekiniki yumuriro w'amashanyarazi ukomoka kuri gride ihuza imirasire y'izuba (NB / T 32004-2018), ibisabwa kugirango birinde ingufu za volvoltage / undervoltage kuruhande rwibisohoka AC: Iyo voltage kuri AC isohoka ya AC isohoka ryizuba rirenze i byemewe na voltage urwego rwa gride, inverter yizuba yemerewe kuzimya. Zimya amashanyarazi kuri gride hanyuma wohereze ikimenyetso cyo kuburira mugihe cyaciwe. Imirasire y'izuba igomba kuba ishobora gutangira no gukora mubisanzwe mugihe amashanyarazi ya gride agarutse kumurongo wemewe.
Igisubizo:
1. Gerageza gushyira aho bigera kuri sitasiyo yamashanyarazi hafi yumusozo wa transformateur kugirango ugabanye umurongo.
2. Gerageza kugabanya umurongo uburebure bwumuriro wizuba wa AC isohoka, cyangwa ukoreshe insinga nini zumuringa kugirango ugabanye itandukaniro rya voltage hagati yizuba ryizuba na gride.
3. Ubu amashanyarazi menshi ahuza imirasire y'izuba afite imikorere ya AC voltage yo kugenzura. Urashobora kuvugana nuwabikoze kugirango yagure umurongo wa voltage kugirango uhuze na gride voltage ihindagurika.
4. Niba bishoboka, ibisohoka voltage ya transformateur irashobora kugabanuka neza.
Kurwanya ubukana buke
impamvu y'ikibazo:
Imirasire y'izuba ifite umurimo wo gutahura inzitizi ziterwa na DC. Iyo ibonye ko inzitizi nziza ya DC itari nziza kuri 50kΩ, inverter izuba izatanga raporo "PV insulation impedance ni amakosa make" kugirango ibuze umubiri wumuntu gukora ku gice kizima cyikibaho nubutaka hasi gihe kimwe, bitera ibyago byo guhungabana amashanyarazi. Impamvu zigira uruhare zirimo: DC yamenetse; insinga ya insulasi yangiritse, ibinyabuzima bigaragara neza; ibice bigize bracket hasi ni bibi; ikirere na sitasiyo y'ibidukikije Ubushuhe buri hejuru cyane, nibindi
Igisubizo:
Hagarika imiyoboro yamashanyarazi ya AC na DC, koresha umugozi udasanzwe wa MC4 wo gusenya kugirango ukureho inkingi nziza kandi mbi yumurongo wikizamini cya DC kugirango umenye neza ko ibice bigize ibice byashizweho neza, koresha intera ya megohm, guhuza ikizamini gitukura biganisha ku byiza inkingi yumugozi, hamwe nikizamini cyumukara kiganisha kubutaka, soma impedance gusoma ya buri pole nziza hasi, hanyuma uhuze ikizamini gitukura kiganisha kuri pole mbi yumugozi, hanyuma usome impedance isoma ya buri kibi inkingi hasi. Niba irenze 50kΩ, hasuzumwa ko umugozi wokwizerwa wizewe. Niba ari munsi cyangwa ingana na 50kΩ, hasuzumwa ko hari ikibazo kijyanye numugozi. Urashobora kugenzura umugozi wimiterere yumurongo ukwe kugirango urebe niba hari ibyangiritse cyangwa umubano mubi. Inzitizi nkeya yo gukumira irasobanura ko inkingi nziza nibibi bigenda byizunguruka hasi.
Imiyoboro yamenetse ni ndende cyane
impamvu y'ikibazo:
Imirasire y'izuba irekura module yerekana ko imiyoboro yamenetse ari nini cyane. Kurinda umutekano wumuntu ku giti cye, ihagarika gukora kandi itanga amakuru yamakosa.
Igisubizo:
1. Hagarika PV yinjiza, ongera utangire imashini, urebe niba imashini ishobora gusubira mubisanzwe.
2. Reba niba insinga ya AC y'ubutaka ihujwe n'insinga nzima, bapime niba voltage iri hagati y'insinga z'ubutaka n'insinga nzima ari ibisanzwe, cyangwa ukoreshe icyuma kimeneka kugirango ubimenye.
3. Niba nta sano riri hagati yo gupima insinga zipima ninsinga nzima, birashoboka ko imashini yatemba, kandi ugomba kuvugana nuwabikoze kugirango agufashe.
Umuvuduko wa DC ni mwinshi
impamvu y'ikibazo:
Hano haribintu byinshi byahujwe nibice mumurongo umwe wa PV, bigatuma voltage irenga PV voltage yo hejuru yizuba ryizuba.
Igisubizo:
Reba ibipimo bya inverteri yizuba, umenye ingufu za DC zinjira, hanyuma upime niba umuyaga ufunguye wumurongo wumurongo uri mumurongo wemewe wizuba ryizuba. Niba irenze urwego rwemewe, gabanya umubare wuruhererekane rwibigize mumurongo.
Muri ubwo buryo bumwe, niba amashanyarazi ya PV avugwa ko ari make cyane, reba niba umubare wama module uhujwe murukurikirane ari muto cyane, cyangwa niba inkingi nziza nibibi byumugozi bihujwe bihindagurika, itumanaho rirekuye, ihuriro ni umukene, cyangwa umugozi urakinguye.
Nta cyerekanwa kuri ecran ya sunverter
impamvu y'ikibazo:
1. Nta DC yinjiza cyangwa amashanyarazi yingoboka yo kunanirwa, inverter izuba LCD ikoreshwa na DC, kandi voltage yibigize ntishobora kugera kuri inverter yizuba itangira voltage.
2. PV yinjiza itumanaho ihujwe muburyo butandukanye. Imirongo ya PV ifite inkingi nziza kandi mbi, igomba guhuza kandi ntishobora guhuzwa mukurikirane nandi matsinda.
3. Guhindura DC ntabwo bifunze.
4. Igice kimwe cyaciwe, gitera indi migozi idashobora gukora.
Igisubizo:
1. Koresha multimeter kugirango upime DC yinjiza voltage yizuba ryizuba. Iyo voltage isanzwe, voltage yose nigiteranyo cya voltage ya buri kintu.
