Ukusetshenziswa kohlobo oluvulekile lwe-transformer yamanje enenani lokushintsha

Open-type current transformers for Amadivayisi we-IoT. Le phrojekthi ye-inthanethi Yezinto yethula ukusetshenziswa kweziguquli zamanje zohlobo oluvulekile kumaphrojekthi wokulungisa, indima yama-transformer amanje ohlobo oluvulekile anama-switch, kanye nezinzuzo uma kuqhathaniswa neziguquli ezijwayelekile zohlobo oluvulekile, kuhlanganiswe nokuhlaziywa kwecala lobunjiniyela.

Amagama angukhiye: isistimu yokusabalalisa amandla aphansi-voltage, ukushintsha inani, vula uhlobo, i-transformer yamanje, anti-ukweba, Imishini ye-inthanethi Yezinto

1 Isingeniso

Ngokushintshwa kwamagridi kagesi emadolobheni nasezindaweni zasemakhaya embonini kagesi yezwe lami kanye nokwenza ngcono okuqhubekayo kokuzenzakalelayo kwezinhlelo zokusabalalisa amandla kagesi aphansi., ama-transformers amanje ohlobo oluvulekile, njengengxenye kagesi ebalulekile ezinhlelweni zokusabalalisa amandla kagesi aphansi, ukudlala indima ebaluleke kakhulu ekuguquleni igridi yamandla. Kuya ngokuya kuba sobala ukuthi sekusetshenziswe kakhulu ekukaleni, imitha, ukuvikelwa kwe-relay, ukuqapha uhlelo, ukuvikelwa kwesisekelo kanye nokuhlaziywa kwesistimu yamandla ahlukahlukene.

Nokho, lapho ufaka ama-open-type low-voltage transformers okwamanje emakethe, izibopho zingabotshwa, okubangela ukuthi umgogodla wensimbi ungavaleki ngokuphelele; I-iron cores ephezulu nephansi ayivaliwe, okuthinta ukunemba kwe-transformer noma akukho okukhiphayo kwamanje. I-transformer yamanje yohlobo oluvulekile enevelu yokushintsha ingabuyisela ngempumelelo isimo esingenhla ensimbini noma engemuva, futhi inamathemba abanzi okusebenza kumaphrojekthi wokuqapha amandla.

I-transformer yamanje i-a inzwa esetshenziswa ukukala ijika elishintshayo

2. Isimiso sokusebenza se-transformer yamanje

Umgomo wokusebenza we-open low-voltage current transformer uboniswa kuMfanekiso 1.

Ukusonteka okuyinhloko kwe-transformer yamanje evulekile kuxhunywe kuchungechunge emugqeni ongaphansi kokuhlolwa. I-I1 ingumugqa wamanje, leyo, i-primary current ye-transformer yamanje, futhi i-N1 inombolo yokujika okuyinhloko kwe-transformer yamanje. I-I2 ingumsinga wesibili we-transformer yamanje, I-N2 inombolo yokujika kwesibili kwe-transformer yamanje, futhi i-Z2e iwukuvinjwa kwemishini yesekethe yesibili nezintambo zokuxhuma. Lapho i-primary current ingena isuka kutheminali ye-P1 ye-transformer yamanje futhi iphuma kutheminali ye-P2, lapho i-Z2e yesibili ixhunyiwe, ngokusekelwe kumgomo wokungeniswa kwe-electromagnetic, ukuma kwesibili kwe-transformer yamanje kune-I2 yamanje egeleza isuka ku-S1, kusuka ku-Z2e kuya ku-S2, yakha iluphu evaliwe.

Kusukela kulokhu, kungatholwa ukuthi okwamanje yi-I1×N1=I2×N2 esesimweni esifanele, ngakho-ke I1/I2=N1/N2=K, kanye no-K isilinganiso sokuguqulwa kwe-transformer yamanje. Nokho, njengoba i-iron core ye-open-type yamanje transformer isikiwe, ukusebenza kwe-iron core kuzoba nzima kakhulu, ngakho-ke indawo ye-cross-sectional ye-iron core ye-transformer kumele yandiswe, futhi inani lama-ampere-turn kufanele linyuswe, kanye ne-I1×N1=I2 ×N2≥100AN.

Ngaphezu kwalokho, ngokushintsha inani lokushintsha ku-transformer, lapho ibhande le-transformer lingavaliwe kahle noma i-casing iphukile ngenxa yokuguga kwe-transformer, inkinobho yokushintsha iyavela, okuvalekile kuvame ukuvuleka, ukudluliswa kwesignali kunqanyuliwe, futhi i-transformer ayinakho ukuphuma kwesignali; Lapho i-buckle ye-transformer ijwayelekile, isimo sokushintsha ngokuvamile sivalekile, futhi i-transformer isebenza ngokujwayelekile.

3. Vula uhlobo lwe-transformer yamanje

Ama-open-type amanje ama-transformer asetshenziswa kakhulu kumaphrojekthi wokwakhiwa kabusha kwamagridi kagesi emadolobheni nasezindaweni zasemakhaya embonini. Ibonakala ngokufaka kalula, asikho isidingo sokususa ibha yebhasi eyinhloko, futhi ingabuye isetshenziswe ngogesi. Nokho, ama-low-voltage open-type transformer okwamanje asemakethe anobubi obulandelayo:

(1) I-transformer yamanje yohlobo oluvulekile emakethe ingase ingaboshelwa noma i-iron core ingase ingavalwa ngesikhathi sokufakwa, futhi kungase kube nengozi yokuthi i-transformer iwe noma inqamule ngesikhathi sokusebenza;

(2) Uma i-transformer yamanje yohlobo oluvulekile ivulwa ngokuzenzakalelayo okwesibili ngemva kokufakwa, kuzoba nezinkinga ezifana kungabikho isignali.

Kuhloswe kulokhu kushiyeka okungenhla, AKH-0.66/Ama-transformers amanje we-K-SW angaxazulula izinkinga ezingenhla. Le transformer inokubukeka okuhle, ukufakwa kalula nokugcinwa. Njengoba kuboniswe kuMfanekiso 2, i-transformer inezinzuzo ezilandelayo:

Isisetshenziswa Senzwa Yamanje Ye-Transformer - Ukusetshenziswa kohlobo oluvulekile lwe-transformer yamanje enenani lokushintsha

(1) AKH-0.66/Ama-transformer amanje ochungechunge lwe-K-SW awadingi ukunqanyulwa ngesikhathi sokufakwa, futhi ingaqhutshwa bukhoma, futhi ingafakwa ngqo esizeni ngemva kokuvala, ukunciphisa izindleko zabasebenzi;

(2) AKH-0.66/K-SW uchungechunge transformer yamanje, bangu 4 izintambo zokuhola kule mojuli, izintambo ezimbili zidlulisa isignali yamanje, futhi izintambo ezimbili zidlulisa isignali yokushintsha;

(3) Okwe-AKH-0.66/K-SW uchungechunge transformers zamanje, lapho ibhande lingavaliwe noma i-transformer iguga, igobolondo liphukile, amagobolondo angaphezulu naphansi ayabhampa, umgogodla wensimbi awuxhumani kahle, futhi inamathele egobolondweni elingezansi le-transformer. Inkinobho ephakanyisiwe yoshintsho izovela phezulu, iswishi inqanyuliwe, futhi ukudluliswa kwesignali yenani lokushintsha kuyanqanyulwa, edlala indima ekudaleni ukuthi isiguquli se-open-voltage low-voltage siyeke ukusebenza.

(4) Okwe-AKH-0.66/K-SW uchungechunge transformers zamanje, amagobolondo aphezulu naphansi anezimbobo zokuvala umthofu, okufanele ivalwe ngokushesha ngemva kokufakwa.

4. Ithebula lokuqhathanisa ipharamitha

Ukuvela kwe-AKH-0.66/Uchungechunge lwe-K-SW lwama-transformer amanje lunemisebenzi efana ne-alamu yokuvula engavamile kanye nokubika imicimbi yokuvula nokuvala. Ukuthuthuka ngokushesha kwemboni.
