1 Bayani

Wurin samar da wutar lantarki na PS (Power Supply) yana ba da iko mai mahimmanci ga tsarin lif, wanda aka rarraba zuwa cikintsarin wutar lantarki na al'adakumatsarin wutar lantarki na gaggawa.

Mabuɗin Ƙarfin Wuta

Bayanan kula:

• Matakan ƙarfin lantarki na iya bambanta ta hanyar ƙirar lif (misali, #79 a cikin ɗaki-ƙasa da injina daidai da ƙarfin lantarki #420).

• Koyaushe koma zuwa ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun bayanai.

Tsarin Wuta na Al'ada

1. Tushen Transformer:

   • Input: 380V AC → Fitarwa: Yawan ƙarfin AC / DC ta hanyar iska ta biyu.

   • Ya haɗa da masu gyara don abubuwan fitarwa na DC (misali, 5V don allon sarrafawa).

   • Ana iya ƙara ƙarin taswira don na'urorin saukowa masu ƙarfi ko hasken aminci.

2. Mai Canja wurin DC-DC:

   • Shigarwa: 380V AC → DC 48V → Juyawa zuwa ƙarfin ƙarfin da ake buƙata na DC.

   • Bambancin Maɓalli:

     • Tsarin da aka shigo da shi yana riƙe da ikon AC don saukowa/ manyan tashoshi na mota.

     • Tsarin cikin gida yana canzawa gabaɗaya zuwa DC.

Tsarin Wutar Gaggawa

• (M)ELD (Na'urar Saukowa Gaggawa):

  • Yana kunnawa yayin katsewar wutar lantarki don fitar da lif zuwa bene mafi kusa.

  • Nau'i biyu:

    1. Jinkirin Kunnawa: Yana buƙatar tabbatar da gazawar grid; keɓe wutar lantarki har sai an gama aiki.

    2. Ajiyayyen Nan take: Yana kula da wutar lantarki ta motar bas na DC yayin fita.

Precharge/Fitar Da'irori

• Aiki: Amintaccen caji/fitar da wutar lantarki ta hanyar haɗin DC.

• Abubuwan da aka gyara:

  • Precharge resistors (iyakance inrush halin yanzu).

  • Resistors na fitarwa (watse ragowar makamashi bayan rufewa).

• Gudanar da Laifi: DubaMC Circuitsashe don al'amurran da suka shafi tsarin farfadowa.

2 Gabaɗaya Matakan Magance Matsalar

2.1 Laifin Tsarin Wuta na Al'ada

Batutuwan gama gari:

1. Fuse/Circuit Breaker Tripping:

   • Matakai:

     1. Cire haɗin da'ira mara kyau.

     2. Auna ƙarfin lantarki a tushen wutar lantarki.

     3. Bincika juriya na rufi tare da megohmmeter (> 5MΩ).

     4. Sake haɗa kayan aiki ɗaya bayan ɗaya don gano abin da ba daidai ba.

2. Wutar lantarki mara kyau:

   • Matakai:

     1. Ware tushen wutar lantarki kuma auna fitarwa.

     2. Don masu canzawa: Daidaita fam ɗin shigarwa idan ƙarfin lantarki ya karkace.

     3. Don masu sauya DC-DC: Maye gurbin naúrar idan tsarin wutar lantarki ya gaza.

3. EMI/ Tsangwamar Surutu:

   • Ragewa:

     • Rarrabe manyan igiyoyi masu ƙarfi / ƙananan ƙarfin lantarki.

     • Yi amfani da hanyar kai tsaye don layi ɗaya.

     • Tayoyin kebul na ƙasa don rage radiation.

2.2 Laifin da'ira na Precharge/Fitarwa

Alamun:

1. Wutar Lantarki na Cajin da ba al'ada ba:

   • Bincika precharge resistors don ɗumamawa ko busa fis ɗin thermal.

   • Auna faɗuwar wutar lantarki a tsakanin abubuwan haɗin gwiwa (misali, resistors, igiyoyi).

2. Tsawaita Lokacin Caji:

   • Bincika capacitors, daidaita resistors, da hanyoyin fitarwa (misali, na'urorin gyara, sandunan bas).

Matakan Bincike:

1. Cire haɗin duk haɗin DCP (DC Positive).

2. Auna fitowar da'irar precharge.

3. Sake haɗa da'irori na DCP a hankali don gano hanyoyin fitarwa marasa kyau.

2.3 (M) ELD Laifin Tsarin

Batutuwan gama gari:

1. (M)ELD ya kasa farawa:

   • Tabbatar da siginar wutar lantarki #79 yayin gazawar grid.

   • Duba ƙarfin baturi da haɗin kai.

   • Bincika duk maɓallan sarrafawa (esp. a cikin saitin ƙarancin ɗaki).

2. Rashin Wutar Lantarki (M) ELD:

   • Gwada lafiyar baturi da da'irar caji.

   • Don tsarin tare da masu haɓaka taswira: Tabbatar da shigar da wutar lantarki ta famfo.

3. Rufewar da ba a zata ba:

   • Bincika relays aminci (misali, #89) da siginonin yankin kofa.

3 Laifi gama gari & Magani
