Gukemura ikibazo cyo kwigunga

Niki "ikosa ryo kwigunga"?

Muri sisitemu ya Photovoltaque hamwe na transformateur-idafite inverter, DC yitaruye hasi.Modules hamwe na module ifite inenge, insinga zidafunze, optimizers zidafite imbaraga, cyangwa inverter yimbere irashobora gutera DC kumeneka hasi (PE - isi ikingira).Ikosa nkiryo ryitwa kandi amakosa yo kwigunga.

Igihe cyose inverter ya Renac yinjiye muburyo bwo gukora hanyuma igatangira gutanga ingufu, irwanya hagati yubutaka na DC itwara amashanyarazi irasuzumwa.Inverter yerekana ikosa ryo kwigunga iyo ibonye igiteranyo cyo kurwanya kwigunga kiri munsi ya 600kΩ mugice kimwe, cyangwa 1MΩ mubice bitatu byimbere.

Nigute amakosa yo kwigunga abaho?

1. Mubihe bitose, umubare wibyabaye birimo sisitemu ifite amakosa yo kwigunga byiyongera.Gukurikirana amakosa nkaya birashoboka gusa mugihe bibaye.Akenshi hazabaho amakosa yo kwigunga mugitondo rimwe na rimwe ikabura mugihe ubuhehere bumaze gukemuka.Rimwe na rimwe, biragoye kumenya icyateye amakosa yo kwigunga.Ariko, birashobora gushirwa mubikorwa byo gushiraho nabi.

2. Niba gukingira insinga byangiritse mugihe gikwiye, umuzunguruko muto urashobora kubaho hagati ya DC na PE (AC).Ibi nibyo twita amakosa yo kwigunga.Usibye ikibazo cyo gukingira umugozi, ikosa ryo kwigunga rishobora nanone guterwa nubushuhe cyangwa guhuza nabi mumasanduku yizuba.

Ubutumwa bwikosa bugaragara kuri ecran ya inverter ni "ikosa ryo kwigunga".Kubwimpamvu z'umutekano, mugihe cyose iri kosa rihari, inverter ntishobora guhindura imbaraga zose kuko hashobora kubaho ubuzima bwangiza ubuzima kubice bya sisitemu.

Mugihe cyose hari umuyoboro umwe wamashanyarazi hagati ya DC na PE, ntakibazo gihari kuva sisitemu idafunze kandi ntamashanyarazi ushobora kuyinyuramo.Nubwo bimeze bityo ariko, burigihe witondere kuko hari ingaruka:

1. Igice cya kabiri kigufi-cyisi kwisi cyabaye PE (2) ikora imiyoboro ngufi-yumuzingi binyuze muri modul na wiring.Ibi bizongera ibyago byumuriro.

2. Gukora kuri module birashobora gukomeretsa bikomeye umubiri.

Gusuzuma

Gukurikirana amakosa yo kwigunga

1. Zimya AC ihuza.

2. Gupima kandi wandike urutonde rwumuzunguruko wa voltage yumurongo wose.

3. Hagarika PE (AC isi) nubutaka ubwo aribwo bwose.Kureka DC ihujwe.

- Itara ritukura LED ryerekana ibimenyetso

- Ubutumwa bwikosa bwo kwigunga ntibukigaragara kuko inverter ntishobora gufata gusoma hagati ya DC na AC.

4. Hagarika insinga zose za DC ariko ugumane DC + na DC- kuri buri mugozi hamwe.

5. Koresha DC voltmeter kugirango upime voltage hagati ya (AC) PE na DC (+) no hagati ya (AC) PE na DC - hanyuma wandike voltage zombi.

6. Uzabona ko kimwe cyangwa byinshi byasomwe biterekana 0 Volt (Ubwa mbere, gusoma byerekana amashanyarazi afunguye, hanyuma bikamanuka kuri 0);iyi migozi ifite amakosa yo kwigunga.Umuvuduko wapimwe urashobora gufasha gukurikirana ikibazo.

Urugero:

Ikurikiranyanyuguti hamwe nizuba 9 Uoc = 300 V.

PE na + DC (V1) = 200V (= module 1, 2, 3, 4, 5, 6,)

PE na –DC (V2) = 100V (= module 7, 8, 9,)

Iri kosa rizaba hagati ya module 6 na 7.

ICYITONDERWA!

Gukoraho ibice bitagizwe numugozi cyangwa ikadiri bishobora gutera igikomere gikomeye.Koresha ibikoresho byumutekano bikwiye nibikoresho bipima umutekano

7. niba imirongo yose yapimwe ari sawa, kandi inverter iracyabaho ikosa "ikosa ryo kwigunga", ikibazo cyibikoresho bya inverter.Hamagara inkunga ya tekinike kugirango utange umusimbura.

3. Umwanzuro

"Ikosa ryo kwigunga" muri rusange ni ikibazo kuruhande rwizuba (ikibazo gito cya inverter), cyane cyane bitewe nikirere cyinshi, ibibazo byo guhuza imirasire yizuba, amazi mumasanduku ahuza, imirasire yizuba cyangwa insinga zishaje.
