Umvavanyi wangoku we-Cracteristic Comprehensive Tester, owaziwa ngokuba yi-CT / PT Analyzer, sisixhobo sokuvavanya esisebenza kwiindawo ezininzi esilungiselelwe ngokukodwa ukuvavanywa kobuchwephesha bokukhuselwa kweempawu ze-volt-ampere zangoku, uvavanyo lomlinganiselo wokuguqulwa kunye nocalucalulo lwe-polarity.Inokusetyenziswa kwakhona njenge-transformer.Isixhobo sokulinganisa sovavanyo localulo.Ngeempawu zobunzima obulula, ukusebenza kakuhle kunye nokusebenza okugqwesileyo, kuyimveliso enexabiso eliphantsi.
Enyanisweni, ukuchaneka komhloli we-transformer akuyona isalathisi esibalulekileyo sesixhobo.Kwimimiselo yokuqinisekisa i-transformer, kufuneka ukuba impazamo yovavanyo ebangelwa yi-circuit yonke ayifanele idlule i-20% yezinga le-transformer elivavanyiweyo.Idatha enikezelweyo kumsebenzi kufuneka ibe yinyani.
Iingxaki zobugcisa eziqhelekileyo ngexesha lovavanyo:
GDHG-201P ephathekayo PT/CT Transformer Analyzer
1. Ukusebenza okukhethiweyo kokucoca rhoqo
Ukuqinisekiswa kweTransformer ngumlinganiselo wamaza asisiseko.Ekubeni umgangatho wesibini okhoyo kunye ne-second and tertiary error waveforms yangoku ye-transformer phantsi kovavanyo igqwethekile kakhulu kwaye imodareyithwe ngokuphazamiseka okuphezulu, umvavanyi kufuneka abe nokhetho oluhle lokuphindaphinda.Ukusebenza kwesihluzi, hlukanisa iziseko, kwaye wenze imilinganiselo.Izinto ezibangela ukugqwetheka zintsonkothile kakhulu.Kwi-low-precision ephantsi (ngaphantsi kwe-0.5) yokuvavanya i-transformer ngaphandle kwembuyekezo yentsimbi egcweleyo, ukuphazamiseka ngokubanzi malunga ne-10%, kwaye impembelelo ayibonakali.Umgangatho wesizwe ufuna ukuthotywa kwe-harmonic yomvavanyi ibe ngaphezulu kwe-32dB, eyanele ukusetyenziswa.Nangona kunjalo, xa uvavanya i-high-precision transformers okanye i-transformers ene-cores yentsimbi egcweleyo, isalathisi siphantsi.Akukho mlinganiso wokuqinisekiswa kwekhaya kule projekthi, kwaye abavelisi ngokubanzi bahlala benganiki izikhombisi.Xa kuthengwa isixhobo esitsha, abasebenzisi kufuneka basithelekise kunye nesixhobo esidala ukufumanisa ukuba sithembekile na.
2. Yazisa umthwalo kunye nomdlalo kunye ne-transformer eqhelekileyo
Umthwalo owongezelelweyo owenziwe ngumvavanyi kwi-transformer evavanyiweyo kunye nomthwalo owenziwe ngumvavanyi kwi-transformer eqhelekileyo ilawulwa ngokungqongqo kwimimiselo.Ukuqinisekiswa kwe-metrology yasekhaya ayiboni ezi zalathisi, kwaye abaninzi abavelisi ababoneleli ngezibonakaliso, kodwa sesinye sezizathu eziphambili zedatha yovavanyo eyahlukeneyo yeeyunithi ezahlukeneyo.
3. Umthwalo womgca
Xa usenza umthwalo u-Z, gcina ukuxhathisa kwe-0.06 ohms kwiingcingo ezidibanisayo (ezinye zine-0.05 ohms), ngoko ke isixa sokumelana kweengcingo ezintathu A, B, kunye no-C kumfanekiso kufuneka sibe yi-0.06 ohms yokuvavanya.Xa uqinisekisa abaguquli bangoku kwimithwalo emincinci encinci (10VA), ukuchasana kweengcingo kunempembelelo enkulu kwidatha.
4. Intambo ephantsi
Kuba sisilinganisi samaza ombane, indawo ye-electromagnetic field kunye nokubakho okudadayo kunempembelelo enkulu kumlinganiselo.Ekuvavanyeni, ucingo lomhlaba ludlala indima ebalulekileyo.Ucingo lomhlaba kufuneka lubekwe ngokufanelekileyo ngokwemigaqo, ebaluleke kakhulu xa kuhlolwa ngaphezu kwe-0.05 okanye i-voltage ephezulu.Kucetyiswa ukuba abasebenzisi bakhethe isethi epheleleyo yabenzi bezixhobo abaneminyaka emininzi yesiseko seshishini xa kuthengwa izixhobo, kunokuba bavelisi becandelo elinye.Kukho umahluko obalulekileyo phakathi kwezi zimbini kwithiyori kunye namava ovavanyo lwe-transformer.Ukhetho oluchanekileyo lunokuqinisekisa ukuba izikhombisi zesixhobo zihlangabezana neemfuno zemimiselo.
