Ta yaya PV Array DC Isolator Switch ke Kare Tsarin Hoto?

       PV array DC isolator canza, kamar yadda sunan ya nuna, wani canji ne wanda ke ware DC.Ana amfani da shi mafi yawa a cikin tsarin tashar wutar lantarki na photovoltaic, kuma ana amfani dashi a tsakanin manyan wutar lantarki na DC photovoltaic arrays da grid-connected inverters don yanke arcs da aka samar da wutar lantarki ta DC, kauce wa haɗari masu haɗari, da tabbatar da aiki mai lafiya.Suna kusa da inverter kuma suna buƙatar hanyar ware gabaɗayan tsararrun PV da hannu yayin shigar da tsarin ko duk wani kulawa na gaba.

Menene Ayyukan Kariya na PV Array DC Isolator Switch?

(1) Lokacin shigar da tsarin photovoltaic, mai sakawa yawanci yana kashe maɓallin DC da farko don ware shigar da tsarin hasken rana daga inverter.A lokacin wannan wayoyi da toshe tashoshin DC, wutar DC ba ta haɗa ta da gefen DC na inverter don hana girgiza wutar lantarki ta sirri da lalacewa ga inverter da kayan aiki na baya.Don haka, lokacin shigar da tsarin, muna buƙatar PV array dc isolator don ware ikon DC tsakanin inverter da panel baturi.

(2) A cikin tashar wutar lantarki ta photovoltaic, mai juyawa shine "cibiyar cibiya".Domin tabbatar da isasshen lokacin samar da wutar lantarki, inverter ba shi da maɓallin farawa.Muddin akwai haske (ko da a lokacin damina), na'urorin hasken rana na iya samar da wutar lantarki kuma injin inverter na iya aiki ta atomatik.Duk da haka, wannan kuma yana kawo matsala.Lokacin sauyawa ko gyara inverter, ko da yake an cire haɗin gefen AC ta hanyar na'ura mai ba da wutar lantarki da aka shigar, gefen DC koyaushe yana ƙarfafawa.A wannan yanayin, idan inverter ba shi da array array dc isolator canji don ware ikon DC na bangarori, yana da sauƙi don haifar da girgiza wutar lantarki da lalacewar kayan aiki.

(3) A halin yanzu, yawancin inverters a kasuwa sune jerin TL, wato, babu keɓewar lantarki a ciki, kuma akwai yuwuwar juyar da kwarara daga gefen AC zuwa gefen DC.A lokacin kiyayewa, idan canjin AC da na'urar DC sun keɓe a zahiri, ana iya samun ƙarin kariya.

Nau'in Shigarwa Daban-daban

Siffofin Slocable PV Array DC Masu Isolators:

1. Musamman an tsara shi don aikace-aikacen DC, ƙimar halin yanzu 16 ~ 630A, ƙarfin lantarki: ≤1500V, dace da aikace-aikace daban-daban;

2. Hanyoyin shigarwa daban-daban da ƙirar ƙira suna ba da sassaucin shigarwar samfurin;

3. Ƙaddamar da wutar lantarki ta tsaftace kai, yana rage juriya da amfani da makamashi, da kuma tsawaita rayuwar sabis;

4. Yawan sanduna: 2 ~ 10 matakan zaɓi;

5. Matsakaicin lokacin kashewa: ƙasa da 5ms

6. Ana amfani da UL94V-0 da aka shigo da kayan wuta na wuta, wanda za'a iya amfani dashi a cikin yanayin aikace-aikace mai tsanani;

7. Yi biyayya da ka'idoji daban-daban (kamar IEC, UL, TUV, CE, CB, SAA, CCC, da sauransu)

Slocable iya samar da PV tsararrun ware masu dacewa da cikakken kewayon kirtani inverters daga 1KW zuwa 320KW.Yana da mai siyar da keɓancewar wutar lantarki na DC daidai da IEC60947-3(ed.3.2):2015 kuma ya sami takardar shedar UL.

Waɗannan samfuran da ke bin sabbin ka'idodin hoto na hoto na iya saduwa da buƙatu masu fa'ida na kasuwar hoto ta duniya kuma suna iya magance damuwar abokan ciniki game da amincin tsarin da kariyar.Slocable zai ci gaba da gudanar da bincike mai zurfi don samar da kasuwa tare da bambance-bambancen da zaɓaɓɓu mafi kyau.
