Isiteshi esincane esenziwe ngaphambili, esaziwa nangokuthi isiteshi esincane esenziwe ngaphambilini.Iwumshini wokusabalalisa amandla ohlangene wangaphakathi nangaphandle owakhelwe ngaphambili ohlanganisa i-switchgear enamandla kagesi, i-transformer yokusabalalisa kanye nedivayisi yokusabalalisa amandla ane-voltage ephansi ngokohlelo oluthile lwezintambo.I-transformer step-down, i-low-voltage distribution kanye neminye imisebenzi ihlanganiswe ndawonye, ifakwe ebhokisini lensimbi elivalwe ngokugcwele nelihambahambayo elingangenwa umswakama, lingagqwali, lingangenisi uthuli, lingangeni kumagundane, livimbe umlilo, linqande ukweba, kanye nokushisa. ukwahlukanisa.Isiteshi esincane sohlobo lwebhokisi silungele izimayini, izimboni, izizinda zikawoyela negesi kanye neziteshi zamandla omoya.Ingena esikhundleni samagumbi okuqala okusabalalisa ukwakhiwa komphakathi kanye neziteshi zikagesi futhi iba isethi entsha ephelele ye-transformer kanye nezisetshenziswa zokusabalalisa.
Izici:
1. Iphephile futhi Inokwethenjelwa
I-Shell ngokuvamile isebenzisa ipuleti lensimbi ye-aluminium zinc, uhlaka olunezinto ezijwayelekile zesiqukathi kanye nenqubo yokukhiqiza enokusebenza okuhle kokunqanda ukugqwala iminyaka engu-20 okuqinisekisiwe.Ipuleti lokuvala langaphakathi lenziwe ngepuleti le-aluminium alloy buckle, futhi isemishi lenziwe ngezinto ezingashi futhi ezishisayo.I-air conditioning ne-dehumidification device ifakwe ebhokisini.Ukusebenza kwemishini akuthintwa imvelo yemvelo yesimo sezulu kanye nokungcola kwangaphandle, futhi ukusebenza okuvamile kungaqinisekiswa ngaphansi kwemvelo enokhahlo engu -40 ℃ ~ +40 ℃.Imishini eyinhloko ebhokisini ivalwe ngokugcwele, umkhiqizo awunayo ingxenye ebukhoma eveziwe, engafinyelela ngokuphelele ingozi yokushaqeka kagesi eyiziro, isiteshi sonke singakwazi ukubona ukusebenza okungenawo uwoyela, ukuphepha okuphezulu, ukusetshenziswa kwesibili kwe-microcomputer edidiyelwe ye-automation system, okuyinto angabona engagadiwe.
2. Izinga eliphakeme lokuzenzakalelayo
Ingqikithi yomklamo ohlakaniphile wesiteshi, isistimu yokuvikela isebenzisa okokusebenza okuzenzakalelayo kwe-microcomputer substation, ukufakwa, okukwazi ukubona i-telemetry, ukuxhumana okukude, isilawuli kude, ukulawula okukude.Iyunithi ngayinye inomsebenzi wokusebenza ozimele.Umsebenzi wokuvikela i-relay uqedile, ongabeka imingcele yokusebenza kude, ulawule umswakama nezinga lokushisa emzimbeni webhokisi futhi uxwayise intuthu ekudeni, ukuze uhlangabezane nezidingo zomuntu osemsebenzini.Ingakwazi futhi ukuqaphela ukuqapha isithombe esikude ngokwesidingo.
3. Ukwakhiwa kwefekthri
Lapho uklama, inqobo nje uma umklami ngokwezidingo zangempela zesiteshi esincane, ehlinzeka ngomdwebo oyinhloko wezintambo kanye nomklamo wemishini engaphandle kwebhokisi, abakhiqizi bangakwazi ukufaka nokulungisa iphutha layo yonke imishini, baqaphele ngempela imboni yokwakha yesiteshi, finyeza umjikelezo wokuklama nowokukhiqiza.Ukufakwa endaweni kudinga kuphela ukuma kwebhokisi, ukuxhunywa kwekhebula phakathi kwamabhokisi, uxhumo lwekhebula eliphumayo, ukulinganisa kokuvikela, ukuhlolwa kokudlulisela kanye nomunye umsebenzi wokuthuma.Sonke isiteshi esingaphansi kusukela ekufakweni kuya ekusetshenzisweni sidinga kuphela izinsuku ezi-5 ~ 8, sifinyeza kakhulu isikhathi sokwakha.
4. Imodi yokuhlanganisa eguquguqukayo
Isakhiwo sesiteshi esincane sebhokisi sihlangene, ibhokisi ngalinye lakha uhlelo oluzimele, okwenza inhlanganisela yokuguquguquka, ngakolunye uhlangothi, sonke singasebenzisa ibhokisi, ukuze imishini ye-35kV ne-10kV ifakwe ebhokisini, ukwakheka kwayo yonke. uhlobo lwebhokisi elincane;Impahla ye-35kV ingafakwa ngaphandle, futhi okokusebenza kwe-10kV kanye nohlelo lokulawula nokuvikela lungafakwa ngaphakathi kwebhokisi.Le modi yokuhlanganisa ifaneleka ngokukhethekile ukuguqulwa kweziteshi zegridi zamandla zasemakhaya ezindala.Ngamafuphi, ayikho imodi yenhlanganisela engaguquki yesiteshi esincane esihlangene, futhi umsebenzisi angahlanganisa ezinye izindlela ngokukhululekile ngokuya ngesimo sangempela ukuze ahlangabezane nezidingo zokusebenza okuphephile.
5. Ukonga izindleko
Isiteshi esincane sohlobo lwebhokisi sehlisa ukutshalwa kwezimali ngo-40% ~ 50% uma kuqhathaniswa nesiteshi esincane esivamile sesikali esifanayo.Ubunjiniyela bomphakathi (kuhlanganise nezindleko zokutholwa komhlaba) besiteshi esincane sohlobo lwebhokisi bungaphezu kwesigidi esingu-yuan esingaphansi kwalesi sesiteshi esivamile esisekelwe ekubalweni kwesikali esingu-4000kVA sesiteshi esincanyana esisodwa esingu-35kV. Ngokombono wokusebenza, ibhokisi -uhlobo lwesiteshi esingaphansi singakwazi ukulungisa isimo, sinciphise umsebenzi wokulungisa, futhi songe cishe ama-yuan angu-100,000 wokusebenza nokulungiswa njalo ngonyaka, futhi inzuzo yomnotho iyonke inkulu kakhulu.
6. Indawo encane ehlala abantu
Uma sithatha isiteshi esingaphansi esisodwa esingu-4000kVA njengesibonelo, ukwakhiwa kwesiteshi esincane esivamile esingu-35kV kuzothatha indawo engaba ngu-3000㎡ futhi kudinga ubunjiniyela bomphakathi obusezingeni eliphezulu. kuphela ngesilinganiso esifanayo sesiteshi esincane sihlanganisa indawo engu-1/10, singafakwa phakathi nendawo yomgwaqo, isikwele kanye nekhona lemboni, ngokuhambisana nenqubomgomo kazwelonke yokonga umhlaba.
7. Isimo esihle
Idizayini yomumo webhokisi muhle, ngesisekelo sokuqinisekisa ukuthembeka kokunikezwa kwamandla, ngokukhethwa kombala wegobolondo lebhokisi lesiteshi, kulula kakhulu ukuxhumanisa nendawo ezungezile, elungele ukwakhiwa kwamadolobha, ingasetshenziswa njengesiteshi esincane esingaguquki, ingasetshenziswa futhi njengesiteshi esincane esihambayo, esinendima yokuhlobisa kanye nokuhlobisa imvelo.
