Umqondo Oyinhloko: Yini Echaza Isiteshi Esincane Esincane?
Aisiteshi esincane-eyaziwa nangokuthi aisiteshi esincane esihlangenenomaisiteshi esincane-iyunithi yokusabalalisa amandla ehlanganiswe ngokugcwele ehlanganisa:
- I-Medium-voltage switchgear
- I-transformer yokusabalalisa
- Iphaneli ye-low-voltage
- Zonke zigcinwe endaweni evikela isimo sezulu, ehlanganiswe efekthri
Lezi ziteshi ezingaphansi ngokuvamile ziphatha100 kVA kuya ku-2500 kVAfuthi usebenze ngaphakathi11kV, 22kV, noma 33kV izinhlelo.
Izicelo Zeziteshi Ezincane Ezincane
Iziteshi ezincane zisetshenziswa kabanzi ku:
- Izakhiwo Zokuhlala Nezohwebo
Ihlinzeka nge-voltage eyehlayo ukuya ku-400V ukuze isetshenziswe ekhaya noma ehhovisi - Izingosi Zezimboni
Ukunika amandla imishini emincane noma amayunithi enqubo yasendaweni - Izitshalo Zamandla Avuselelekayo
Isebenza njengendawo yokuxhumana phakathi kwamapulazi elanga noma omoya kanye negridi yokusetshenziswa - Amayunithi Amandla Eselula
Isetshenziswa ezimayini, ezizindeni zikawoyela, nakumaphrojekthi wokwakha wesikhashana - Ukufaka Ugesi Okukude noma Kwasemakhaya
Ukuletha amandla ezindaweni lapho ukunwetshwa kwegridi kunomkhawulo
Amathrendi ezimakethe kanye nesendlalelo
Njengoba perIEEMAfuthiIEAImibiko, isidingo seziteshi ezincane siyakhula emhlabeni jikelele ngenxa:
- Izinhlelo zokufudukela emadolobheni ngokushesha kanye nokufakwa kukagesi ezindaweni zasemakhaya
- Ukukhula ekufakweni kophahla lwelanga ne-microgrid
- Ukuthembela okwengeziwe ezinhlelweni zamandla asabalalisiwe
- Amaphrojekthi okuthuthukiswa kwedolobha ahlakaniphile
Iziteshi ezingaphansi ezincane, ikakhulukazi izinhlobo ezakhiwe ngaphambili nezifakwe eqhweni, ziyingxenye ebalulekileamasu amandla endlalekile, ihlinzeka ngamandla endawo athembekile ngaphandle komkhondo weziteshi ezingaphansi ezigcwele.
Ngokuvumelana neI-Wikipedia, iziteshi ezincane ezihlangene ziyingxenye yohlelo olubanzi lokuthuthukisa ukusebenza kahle kwamandla nokunciphisa ukulahlekelwa phakathi nokulethwa kwemayela lokugcina.
Ukucaciswa Kwezobuchwepheshe Ngokubuka nje

| Ukuthobela Amazinga | I-IEC 62271, IEC 60076, IEEE C57 |
Iziteshi Ezincane Ezincane Nezinkulu: Uyini Umehluko?
| Isici | Isiteshi esincane | Isiteshi esikhulu |
|---|---|---|
| Amandla Amandla | 100 - 2500 kVA | Ngaphezu kuka-5000 kVA |
| Amazinga kagesi | Kufika ku-33kV | Ifinyelela ku-400kV noma ngaphezulu |
| Unyathela | Kuhlangene (1–3 m²) | Indawo enkulu (izakhiwo eziningi) |
| Isikhathi sokufaka | 1-2 izinsuku | Amasonto noma izinyanga |
| Izinhlelo zokusebenza | Ukusabalalisa kwendawo | Ukulawulwa kwegridi yesifunda |
| Ukwenza ngokwezifiso | Inomkhawulo | Yenza ngokwezifiso kakhulu |
Amathiphu Okuthenga: Ungasikhetha Kanjani Isiteshi Esincane Esincane
Lapho ukhetha i-substation encane, cabanga:
- Isidingo Sokulayisha:Nquma usayizi we-transformer ngokusekelwe kumthwalo ophezulu (ku-kVA).
- Imvelo:Khetha indawo ebiyelwe enesilinganiso se-IP54+ ezindaweni ezinothuli noma ezinomswakama.
- Uhlobo lwe-Transformer:
- Ukucwiliswa ngamafutha: Isebenza kahle kakhulu futhi iyonga
- Uhlobo olomile: Iphephile ngaphakathi endlini nasezindaweni ezingezwani nomlilo
- Izinhlelo Zokuvikela:Qinisekisa ukuthi iphaneli ye-LV ihlanganisa ama-MCCBs, izivikeli zokuhlinza, namamitha.
- Ukuhamba:Ngokusetshenziswa kwesikhashana, amayunithi afakwe eqhweni noma afakwe nge-trailer alungile.
Abahlinzeki abahloniphekile abanjengoI-ABB,I-Schneider Electric,Siemens, nabakhiqizi abasafufusa bathandaPINEELEinikeza iziteshi ezingaphansi eziqinisekisiwe ze-IEC/ANSI.

imibuzo ejwayelekile ukubuzwa
A:Ngokulungiswa okufanele, iziteshi ezincane zingahlala iminyaka engama-25-30, kuye ngezimo zemvelo kanye nekhwalithi yengxenye.
A:Yebo, zivame ukusetshenziselwa ukwenyusa noma ukwehlisa amandla kagesi ezinhlelweni ze-solar PV futhi zilungele ukusetshenziswa kwamandla ayingxube.
A:Amayunithi amaningikuhlanganiswe efekthrifuthi ilethwe isilungele ukusetshenziswa.
Aencaneumhlahlandlela wesiteshiingaphezu nje kwenguqulo encane yehabhu lamandla elivamile—iyisixazululo esisebenziseka kakhulu, esisebenza kahle, futhi esingaka sokusatshalaliswa kukagesi kwesimanje.
Ngokuqonda izingxenye, izindinganiso, nezinketho zokumisa, onjiniyela nabathatha izinqumo bangakhetha isisombululo esifanele esilinganisa izindleko, ukusebenza, nokwethembeka.
