Uchungechunge lwe-EVT/ZW32-10 i-Voltage Transformers
Ukugxeka
Uchungechunge lwe-EVT / ZW32--10 i-voltage transformers luhlobo olutsha lomlinganiselo wombane ophezulu kunye nokukhusela i-transformers, ngokukodwa ehambelana ne-ZW32 i-vacuum circuit breaker yangaphandle.I-transformers inemisebenzi enamandla, imveliso yesignali encinci, ayifuni ukuguqulwa kwe-PT yesibini, kwaye inokuqhagamshelwa ngokuthe ngqo kwisixhobo sesibini ngokuguqulwa kwe-A / D, ehlangabezana nophuhliso "lwedijithali, olukrelekrele kunye nothungelwano" kunye "nenkqubo ye-automation edibeneyo. yesikhululo esingaphantsi".
Iimpawu zoLwakhiwo: Inxalenye yombane kolu luhlu lweziguquli zisebenzisa i-capacitive okanye i-resistive voltage division, i-epoxy resin casting, kunye nomkhono werabha ye-silicone.
■ Idibanisa umlinganiselo wangoku kunye nombane kunye nemveliso yomqondiso wokukhusela, kwaye ikhupha ngokuthe ngqo izibonakaliso zombane ezincinci, ukwenza lula inkqubo kunye nokunciphisa imithombo yempazamo.
■ Ingaqulathi umbindi wentsimbi (okanye iqulathe umbindi wentsimbi omncinci), ayinakuhluza, uluhlu lokuphendula amaza amaninzi, uluhlu olukhulu lomlinganiselo, umgca olungileyo, isakhono esinamandla sokuchasa uphazamiseko, kwisixokelelwano seempazamo sinokwenza isixhobo sokhuseleko sisebenze ngokuthembekileyo.
■Xa i-terminal ye-voltage output imfutshane-circuit okwesibini, musa ukuvelisa i-overcurrent, kwaye ayinayo i-ferromagnetic resonance, ephelisa ingxaki enkulu efihlakeleyo yeengozi ekusebenzeni kwenkqubo yamandla kwaye iqinisekise ukhuseleko lwabasebenzi nezixhobo.
■ Imisebenzi emininzi, ubungakanani obuncinci, ubunzima obulula, ukusetyenziswa kwamandla aphantsi, ukunciphisa ungcoliseko lwe-ferromagnetic

Indlela yokufakela
I-transformer eyakhelwe-ngaphakathi kwi-breakers circuit kwaye uyilungise rhoqo kwi-bracket
I-transformer iqhagamshelwe kwisixhobo sombane okanye isixhobo sokukhusela ngentambo ehlanganisiweyo ekhuselweyo, kwaye isikhuselo sentambo sisekelwe kwisoftware yokumisa okanye isiseko sentsimbi.
Imilinganiselo kwiimilimitha
Ukuodola Ulwazi
Xa u-odola, nceda udwelise imodeli yemveliso, iiparitha eziphambili zobugcisa (i-voltage elinganisiweyo, inqanaba elichanekileyo, iiparitha zesibini ezilinganisiweyo) kunye nobuninzi.ukuba kukho iimfuno ezikhethekileyo, nceda uqhagamshelane nenkampani
