Iimpawu zeSixhobo soVavanyo lweTransformer yangoku-Ephathekayo CT/PT Tester
I-1.Imisebenzi ebanzi, engahambelani kuphela neempawu zokuvuselela (okt iimpawu ze-volt-ampere), umlinganiselo wokuguqulwa, i-polarity, ukuxhatshazwa kwesibini, umthwalo wesibini, umahluko womlinganiselo kunye nokwahlukana kwe-angular yee-CTs ezahlukeneyo (njengokukhusela, ukulinganisa, i-TP) ingasetyenziselwa ukuvavanya iimpawu zokuvuselela, umlinganiselo wokuguqulwa, i-polarity, kunye nokumelana nokunyuka kwesibini kweeyunithi ezahlukeneyo zombane we-PT.
I-2.I-Inflection point voltage/current, 10% (5%) ijika lempazamo, i-acuracy limit factor (ALF), isixhobo sokhuseleko (FS), ixesha lesibini elingatshintshiyo (Ts), i-remanence factor (Kr), i-saturation inductance, njl. inikwe ngokuzenzekelayo i-CT ne-PT iiparamitha.
3. Ukuthobela imigangatho eyahlukeneyo ye-transformer efana ne-IEC 60044-1, i-IEC 60044-6, ikhetha ngokuzenzekelayo ukuba yeyiphi imigangatho yokuvavanya ngokohlobo kunye nenqanaba le-transformer.
I-4.Ngokusekelwe kumgaqo-nkqubo wokuvavanya indlela ephantsi ye-low-frequency, inokumelana neemvavanyo ze-CT ezinamanqaku e-inflection aphezulu njenge-40KV.
5. Yamkela indlela yamazwe ngamazwe ethandwayo yesikwere yamaza.
6.Ugcino lweData ukuya kuthi ga kwiseti yamawaka alikhulu, akukho kulahleka xa umbane ucinyiwe. Yenza ingxelo ye-Excel ngqo emva kokuba uvavanyo lugqityiwe.
7.Uvavanyo lulula kwaye lufanelekile. Ukuchasana ngokuthe ngqo, ukuvuselela, umlinganiselo wokuguqulwa kunye novavanyo lwe-polarity lwe-CT lunokugqitywa ngokushicilela omnye. zonke ezinye iimvavanyo ze-CT zisebenzisa indlela yocingo efanayo ngaphandle kovavanyo lomthwalo.
8.Ephathekayo, kuphela 6 KG.
