Uchungechunge EVT/ZW32-10 Voltage Transformers
Ukweyisa
Uchungechunge lwe-EVT/ZW32--10 ama-voltage transformer wuhlobo olusha lwesilinganiso samandla kagesi aphezulu kanye nama-transformer okuvikela, ikakhulukazi afaniswe ne-ZW32 vacuum circuit breaker yangaphandle.Ama-transformer anemisebenzi enamandla, okukhipha isignali encane, awadingi ukuguqulwa kwe-PT yesibili, futhi angaxhunywa ngokuqondile kumishini yesibili ngokuguqulwa kwe-A/D, ehlangabezana nokuthuthukiswa "kwedijithali, ehlakaniphile nenethiwekhi" kanye "nohlelo oluzenzakalelayo lwe-automation. wesiteshi".
Izici zesakhiwo: Ingxenye ye-voltage yalolu chungechunge lwama-transformer isebenzisa ukuhlukaniswa kwe-capacitive noma resistive voltage, i-epoxy resin cast, kanye nomkhono werabha we-silicone.
■ Ihlanganisa ukulinganisa kwamanje kanye ne-voltage kanye nokuphumayo kwesignali yokuvikela, futhi ikhiphe ngokuqondile amasignali amancane kagesi, yenza ukwakheka kwesistimu kube lula nokunciphisa imithombo yamaphutha.
■Ingaqukathi i-iron core (noma iqukethe i-iron core encane), ngeke igcwale, ububanzi bokuphendula imvamisa, ububanzi bokulinganisa obukhulu, umugqa omuhle, ikhono eliqinile lokulwa nokuphazamiseka, esimweni sephutha lesistimu kungenza idivayisi yokuvikela isebenze ngokuthembekile.
■Lapho itheminali yokuphuma kwamandla kagesi ifinyezwa okwesibili, ingakhiqizi i-overcurrent, futhi ingenayo i-ferromagnetic resonance, eqeda izingozi ezinkulu ezifihliwe ekusebenzeni kwesistimu kagesi futhi iqinisekise ukuphepha kwezisebenzi nemishini.
■ Imisebenzi eminingi, usayizi omncane, isisindo esincane, ukusetshenziswa kwamandla okuphansi, ukunciphisa ukungcoliswa kwe-ferromagnetic

* QAPHELA : 25.8kV Ikhefu Lokulayishwa Okuqinile Shintshela Izindlu - Itheminali / Isikhunta - Uhlobo lwekhoni (Inketho)
Indlela yokufaka
I-transformer eyakhelwe ngaphakathi kuma-circuit breaker futhi uyilungise njalo kubakaki
I-transformer ixhunywe kuthuluzi le-elekthronikhi noma idivayisi yokuvikela ngentambo eyinhlanganisela evikelekile, futhi isivikelo sekhebula simiswa ngesofthiwe ephansi noma isisekelo sensimbi.
Ubukhulu ngamamilimitha
Uku-oda Ulwazi
Lapho u-oda, sicela ubhale imodeli yomkhiqizo, imingcele yobuchwepheshe eyinhloko (i-voltage elinganiselwe, izinga elinembile, imingcele elinganiselwe yesibili) kanye nenani.uma kunezidingo ezikhethekile, sicela uxhumane nenkampani
