Uchungechunge YTJLW10-720 Voltage Transformers
Ukweyisa
Ukulandelana kwesigaba se-Series YTJLW10-720, i-voltage enguziro yokulandelana kanye ne-transformer yamanje iwuhlobo lwama-AC transformer anemininingwane yobuchwepheshe evumelana nemishini yokuhlanganisa eyinhloko neyesibili ye-State Grid futhi ngokuhambisana ne-T/CES 018-2018 "Distribution Network 10kV and I-20kV AC Transformers Technical Conditions". Iziguquli zamandla kagesi, zamanje kanye namandla zakhiwe emkhiqizweni, ezingahlanganiswa ngokuqondile ne-circuit breaker yakhe i-intelligent vacuum circuit breaker.elula ukuyifaka, ukusetshenziswa kwamandla okuphansi, ukunemba okuphezulu kanye nesilinganiso esizinzile.
■ I-capacitor eyinhloko isebenzisa amandla alinganayo ukuze iqoqe i-voltage, enokuqina okuhle kwesikhathi eside kanye nesipiliyoni sokusebenza isikhathi eside kumagridi kagesi.
■ Ukumelana kwangaphakathi okukhiphayo kuncane, okungakwazi ukuzivumelanisa nezintambo ezihlukahlukene, kunqobe iphutha elibangelwa izintambo, futhi iphutha lokushintshanisa ikhebula lingaphansi kuka-0.1%.
■ uguquko oluncane lokunemba oluthintwa izinga lokushisa elizungezile, kanye noshintsho olukhulu lwephutha lungaphansi kuka-0.5% ebangeni lokushisa eligcwele lika -40 °C ~ 70 °C, elihlangabezana ngokugcwele nezidingo zenkomba yokuhluka kwezinga lokushisa kwezinga elingu-3. i-transformer icacisiwe.
■ ithatha ukumelana kwamandla okuzinze ngokwedlulele kanye nokuvuthwa kwamandla aphansi, ukuqina okuhle kokuphumayo nokunemba okuphezulu, futhi ihlangabezana nezimo zokusebenza zazo zonke izimo zokusebenza

Ubukhulu ngamamilimitha
Indlela yokufaka
Imiyalelo yokufaka nezinyathelo zokuphepha
■ Qinisekisa ukuthintana okuthembekile phakathi kwentambo yaphansi nendlu ngesikhathi sokufakwa.
■ Imikhondo yesignali yesibili ye-transformer kufanele ixhunywe eduze nebhokisi, futhi imikhondo eyeqile kufanele ifinyezwe.
■ I-voltage yesibili ephumayo ye-transformer phansi ayivunyelwe ukusebenza imvamisa ukumelana ne-voltage
■ Imiyalo yezintambo zesibili
| UHLOBO | Isilinganiso soguquko esilinganiselwe | Ukuhlonza i-outlet | phawula |
| Ukulandelana kwesigaba samanje | 600A/1V | Ia+Ia-,Ib+Ib-,Ic+Ic- | |
| Ukulandelana kwamanje kuziro | 20A/0.2V | I0+ I0- | I-Identity I0+ I0- njengemigqa yenguquko ye-Connect |
| Ukulandelana kwesigaba se-voltage | 10kV/√3/3.25V/√3 | Ua+Ua-Ub+Ub- Uc+Uc- | |
| Ukulandelana kwe-Voltage zero | 10kV/√3/6.5V/3 | U0+ U0- | I-Identity U0+ njengemigqa yenguquko ye-Connect |
Njengoba i-voltage ye-zero-sequence yamanje kanye ne-zero-sequence idinga ukuhlanganiswa kwezigaba ezintathu, kunesidingo sokuxhuma komugqa wokushintsha okuphakathi, isigaba ngasinye I0+, I0- sihambisana nokuxhuma;I-U0+ yesigaba ngasinye ihambisana nokukhwelana.Ngaphambi kokushiya imboni, umkhiqizo udokhiwe, Sicela uwumake lapho ufaka.Ngokulandelayo:
