Me Yasa Na'urar Katse Wutar Lantarki Ta Ke Da Muhimmanci A Tsarin Faifan Rana?
1. Yana kare daga yawan wutar lantarki da kuma gajeren da'ira
Abubuwan da ke cikin tashar wutar lantarki ta hasken rana—kamar kebul na PV, masu haɗawa, akwatunan haɗa kaya, da inverters—suna da iyakokin wutar lantarki masu aminci. Idan wutar ta wuce waɗannan iyakokin, zafin kebul zai ƙaru, rufin zai iya lalacewa, kuma wuraren haɗin na iya yin zafi.

4. Cika Ka'idoji da Dokokin Tsaro
Yawancin ƙa'idodin shigarwa na lantarki suna buƙatar kariyar wutar lantarki da kuma cire na'urori a wasu wurare. A cikin kyakkyawan shigarwa na panel ɗin hasken rana, na'urorin katse wutar lantarki da sauran na'urorin kariya (kamar SPDs) wani ɓangare ne na aikin yau da kullun don tabbatar da cewa shigarwar tana da aminci kuma an yarda da ita don dubawa.
Nau'ikan Masu Katse Wutar Lantarki a Tsarin Wutar Lantarki ta Rana
1. MCB (Ƙaramin Mai Katse Da'ira)
Ana amfani da MCBs gabaɗaya don kariyar wuce gona da iri akan ƙananan kaya zuwa matsakaici, musamman a gefen AC (fitarwa ta inverter zuwa panel ɗin rarraba gida). MCBs suna da lanƙwasa na tafiya (misali, nau'ikan B, C, D) waɗanda ke ƙayyade yadda suke tafiya da sauri lokacin da wutar lantarki ta tashi.
2. MCCB (Mai Katse Layin Case Mai Molded Case)
Ana amfani da MCCBs don manyan kwararar wutar lantarki da kuma ƙarfin fashewa mai yawa. A cikin manyan tsarin wutar lantarki na hasken rana - misali, inverters masu ƙarfi ko shigarwar kasuwanci - galibi ana zaɓar MCCBs don babban gefen AC ko takamaiman layukan da ke buƙatar ƙimar mafi girma.
3. Mai Katse Da'ira na DC
Wannan shine bangaren da aka fi fahimta ba tare da fahimta ba. Masu karya da'ira na DC ba iri ɗaya bane da masu karya da'ira na AC. Wutar lantarki ta DC tana da wahalar katsewa saboda arc ɗin ya fi karko kuma baya ketare sifili kamar AC. Saboda haka, masu karya da'ira na DC an tsara su musamman da wata hanyar kashe baka daban.
Ana amfani da DC breakers a cikin:
- Hanyar panel na hasken rana (kitson PV) zuwa akwatin haɗawa
- Layin akwatin haɗawa zuwa inverter
- Hanyar baturi zuwa inverter/caja (a kan tsarin haɗin gwiwa/kashe-grid)
4. Maɓallin Mai Rage Haɗawa/Cire Haɗawa
Duk da cewa ba na'urar yanke wutar lantarki ba ce, wadda ke da kariyar wutar lantarki mai yawa, masu raba wutar lantarki suna da mahimmanci a matsayin masu cire wutar lantarki da hannu don tabbatar da cewa an raba wutar lantarki gaba ɗaya yayin gyarawa. Yawancin shigarwa suna haɗa ayyukan na'urar yanke wutar lantarki da na'urar raba wutar lantarki, amma har yanzu yana da mahimmanci a tabbatar da cewa ƙayyadaddun bayanai sun cika buƙatunku.
Wuraren Sanya Mai Katse Da'ira a Tsarin Faifan Rana
Domin ya zama mai tasiri, bai kamata a sanya na'urorin fashewa na da'ira ba tare da an yi su ba. Gabaɗaya, wasu muhimman wurare sune:
1. Gefen DC tsakanin PV da inverter
– Yana kare kebul na DC da shigarwar inverter daga overcurrent ko gajerun da'irori.
2. Akwatin haɗawa (idan akwai igiyoyi da yawa)
– Kowace igiya galibi ana ba ta kariya, musamman lokacin da tsarin layi ɗaya zai iya haifar da juyawar wutar lantarki daga wasu igiyoyi.
3. Bangaren batirin (don tsarin da ke da ajiya)
– Batirin yana da ikon isar da wutar lantarki mai ƙarfi sosai. Kariya mai kyau ga layukan batirin yana da mahimmanci don hana haɗari masu tsanani.
4. Gefen AC na fitarwa na inverter
- Yana kare nauyin gida da kebul na shigarwa, kuma yana aiki azaman wurin cire haɗin idan akwai matsala a gefen AC.
Yadda Ake Zaɓar Mai Katsewar Da'ira Mai Daidai
Zaɓar mai karya da'ira don tashar samar da wutar lantarki ta hasken rana dole ne ya ɗauki muhimman sigogi da dama:
1. Matsayin Wutar Lantarki
– Tabbatar cewa na'urar yanke wutar lantarki ta DC tana da ƙimar ƙarfin lantarki na DC da ta isa ga ƙarfin lantarki na igiyar PV (misali 600V DC, 1000V DC, ko kamar yadda aka tsara).
2. Matsayin Yanzu
- An ƙayyade bisa ga matsakaicin wutar lantarki na da'irar, la'akari da abubuwan tsaro da zafin muhalli.
3. Ƙarfin Karyewa (Ikon Karya Wutar Lantarki)
– Dole ne ya isa ya jure wa da kuma karya duk wani gajeren wutar lantarki da zai iya faruwa.
4. Lanƙwasa da Halayen Load
– Ga ɓangaren AC, zaɓin lanƙwasa (B/C/D) an daidaita shi da nau'in kaya da yuwuwar ƙaruwar wutar lantarki.
5. Ma'auni da Takaddun Shaida
– Yi amfani da kayayyakin da suka cika ƙa'idodi masu dacewa domin a iya amincewa da aikin kariyarsu.
6. Inganci da Dacewa ga DC
– Kada a yi amfani da na'urar AC MCB ta yau da kullun don layukan DC masu ƙarfin wutar lantarki mai yawa, domin yana da haɗarin rashin karyewa da kuma haifar da mummunan tasirin wutar lantarki.
Kesalahan Umum yang Harus Dihindari
Wasu kurakurai da ake yawan samu a fannin sun haɗa da:
– Amfani da na'urorin fashewa na AC don gefen DC, musamman a babban ƙarfin lantarki na PV.
– Matsayin da ake da shi a yanzu ya yi yawa, don haka na'urar karya ba ta yin kasa a gwiwa idan aka samu cikas.
– Sanya ba daidai ba, misali babu na'urar fashewa a layin batirin.
– Shigar da haɗin da ba shi da kyau, wanda ke haifar da zafi fiye da kima da kuma gazawar da zai iya faruwa.
– Yin watsi da ƙarin kariya kamar SPD, rashin isasshen ƙasa, ko rashin na'urar raba ruwa da hannu.
