Yazvino Transformer Characteristic Comprehensive Tester, inozivikanwawo seCT / PT Analyzer, iri-inoshanda-pa-saiti yekuyedza chiridzwa chakanyatsogadzirirwa relay yekudzivirira inyanzvi yekuongorora yeazvino transformer volt-ampere maitiro, shanduko yechiyero kuyedzwa uye polarity rusarura.Inogonawo kushandiswa se transformer.Chiyero chekuyeresa chekuongorora polarity rusarura.Nehunhu hwehuremu huremu, kushanda kuri nyore uye kuita kwakanakisa, chigadzirwa chinodhura.
Kutaura zvazviri, kururamisa kwemuongorori we transformer haisi chiratidzo chinokosha chechimbo.Mune iyo transformer verification mirau, inodikanwa kuti chikanganiso chebvunzo chakakonzerwa nedunhu rese hachifanire kudarika 20% yeyakaedzwa shanduri level.Iyo data inoratidzwa mubasa inofanira kuva yechokwadi.
Matambudziko akajairika ehunyanzvi panguva yekuyedzwa:
GDHG-201P Inotakurika PT/CT Transformer Analyzer
1. Frequency selective filter performance
Transformer verification ndiyo kuyerwa kwemafungu akakosha.Sezvo chiyero chechipiri chemazuva ano uye chechipiri uye chepamusoro chikanganiso ikozvino waveforms yeshanduko iri pasi pekuedzwa yakakanganiswa zvikuru uye inogadziriswa nekukanganiswa kwepamusoro-frequency, muongorori anofanira kuva nesarudzo yakanaka yefrequency.Sefa kuita, sarudza zvakakosha, uye ita zviyero.Zvinhu zvinokonzera kukanganisa zvakaoma zvikuru.Mune yakaderera-chaiyo (isingasviki 0.5) bvunzo yeshanduko isina yakazadzwa simbi musimboti muripo, kukanganiswa kwakawanda kunosvika gumi muzana, uye pesvedzero haisi pachena.Chiyero chenyika chinoda kuti harmonic attenuation yemuyedzo ive pamusoro pe32dB, inokwana kushandiswa.Nekudaro, kana uchiyedza yakakwira-chaiyo shandurudzo kana matransformer ane saturated iron cores, iyo index yakaderera.Iko hakuna kuyerwa kwekuongororwa kwemumba kweprojekiti iyi, uye vagadziri vese kazhinji havape zviratidzo.Paunenge uchitenga chiridzwa chitsva, vashandisi vanofanirwa kuchienzanisa nechakare kuti vaone kana chakavimbika.
2. Kusuma mutoro uye match pamwe standard transformer
Iyo yakawedzera mutoro inounzwa nemuongorori kune yakaedzwa transformer uye mutoro unounzwa nemuyedzi kune yakajairika transformer inodzorwa zvakanyanya mumirau.Domestic metrology verification haione izvi zviratidzo, uye vazhinji vanogadzira havapi zviratidzi, asi ndechimwe chezvikonzero chikuru che data rakasiyana rebvunzo rezvikamu zvakasiyana.
3. Mutsara mutoro
Paunenge uchigadzira mutoro Z, chengetedza 0.06 ohms yekupikisa waya dzekubatanidza (dzimwe dzine 0.05 ohms), saka huwandu hwekupokana kwewaya nhatu A, B, uye C muhuwandu hunodiwa kuve 0.06 ohms yekuyedza.Paunenge uchiongorora mashanduri emazuva ano pamitoro midiki yakayerwa (10VA), kushorwa kwewaya kune simba guru pane data.
4. Ground cable
Sezvo iri chiyero chemagetsi frequency kuyerwa, nzvimbo yemagetsi magineti uye iyo inoyangarara inogoneka ine simba guru pachiyero.Mukuedza, tambo yepasi inoita basa rinokosha.Iwaya yepasi inofanira kudzika zvakanaka maererano nemirairo, iyo inonyanya kukosha pakuedzwa pamusoro pe 0.05 kana high voltage.Zvinokurudzirwa kuti vashandisi vasarudze seti yakakwana yevagadziri vemidziyo vane makore mazhinji eindasitiri hwaro pavanenge vachitenga zviridzwa, kwete vagadziri vechikamu chimwe chete.Pane misiyano yakakosha pakati pezviviri mudzidziso uye ruzivo rwekuedzwa kweshanduko.Kusarudzwa kwakarurama kunogona kuvimbisa kuti zviratidzo zvechiridzwa zvinosangana nezvinodiwa nemitemo.
