Overview
Ichi chigadzirwa chakakodzera mukati me33kV, 35kV, 36kV, AC system metering nekudzivirira.
Chigadzirwa chacho chinogona kushandiswa chakazvimirira kana kuiswa mumaseti akazara emakabati uye substations.
Ikozvino transformer inotora yakakwira-voltage epoxy resin, kunze kwenyika silicon simbi sheet iron core, iyo inomonereka inotora yakakwirira-insulation enameled waya yemhangura, uye iyo inomonereka nesimbi core inobatwa nepamusoro-mhando semiconductor inodzivirira bepa.
Basic Structure
Iyo yakakosha chimiro cheiyo voltage transformer yakafanana chaizvo neye transformer.Iyo ine zvakare mahwindi maviri, imwe inonzi yekutanga mhepo uye imwe inonzi yechipiri mhepo.Mamhepo ese ari maviri akaiswa kana maronda akatenderedza simbi core.Pane kuvharidzira pakati pemakona maviri uye pakati pemakona nesimbi core, kuitira kuti pave nemagetsi ega ega pakati pemakona maviri uye pakati pemhepo nesimbi core.Kana iyo voltage transformer ichimhanya, iyo yekutanga mhepo inotenderera N1 yakabatana kune mutsara wakafanana, uye yechipiri mhepo inotenderera N2 yakabatana kune chiridzwa kana relay yakafanana.Nokudaro, pakuyera magetsi pamutsara we-high-voltage, kunyange zvazvo magetsi ekutanga akakwirira, yechipiri ishoma-voltage, iyo inogona kuvimbisa kuchengetedzwa kwevashandi uye zviridzwa.
Zvekungwaririra
1. Isati yaiswa voltage transformer mukushanda, bvunzo uye ongororo ichaitwa zvinoenderana nezvinhu zvinotsanangurwa mumirau.Semuenzaniso, kuyera polarity, boka rekubatanidza, kuzunguza insulation, kutevedzana kwechikamu chenyukireya, nezvimwe.
2. Iyo wiring yevoltage transformer inofanirwa kuve nechokwadi chekururama kwayo.Iyo yekutanga mhepo yemhepo inofanirwa kubatanidzwa pamwe chete nedunhu riri pasi pekuyedzwa, uye yechipiri mhepo inotenderedza inofanirwa kubatana pamwe chete nevoltage coil yeyakabatana yekuyeresa chiridzwa, relay yekudzivirira mudziyo kana otomatiki mudziyo.Panguva imwecheteyo, kutarisisa kunofanirwa kubhadharwa kune kurongeka kwepolar..
3. Kusimba kwemutoro wakabatanidzwa kune chikamu chechipiri chemagetsi chemagetsi chinofanira kunge chakakodzera, uye mutoro wakabatanidzwa kune chikamu chechipiri chemagetsi emagetsi haafaniri kudarika simba rayo, kana zvisina kudaro, kukanganisa kweshanduko kuchawedzera, uye zvakaoma kuwana kururamisa kwechiyero.
4. Hapana pfupi pfupi inobvumirwa padivi rechipiri revoltage transformer.Sezvo iyo impedance yemukati yevoltage transformer idiki kwazvo, kana yechipiri dunhu ipfupi-yakatenderedzwa, yakakura ikozvino ichaonekwa, iyo inokuvadza yechipiri midziyo uye kunyange kuisa pangozi kuchengetedzwa kwemunhu.Iyo voltage transformer inogona kuve yakashongedzerwa nefuse padivi rechipiri kuzvidzivirira kubva pakukuvadzwa nepfupi pfupi padivi rechipiri.Kana zvichibvira, fuse inofanirawo kuiswa padivi rekutanga kuchengetedza giredhi yemagetsi emagetsi kubva panjodzi yekuchengetedzwa kwekutanga system nekuda kwekutadza kweiyo transformer's high-voltage windings kana lead waya.
5. Kuti uve nechokwadi chekuchengetedzwa kwevanhu pavanenge vachibata midziyo yekuyera uye relays, yechipiri mhepo yemhepo inoshandura magetsi inofanira kuiswa pasi pane imwe nguva.Nekuti mushure mekugadzika, kana iyo insulation pakati pekutanga neyechipiri windings yakanganiswa, inogona kudzivirira yakakwira voltage yechiridzwa uye relay kubva panjodzi kuchengetedzwa kwemunhu.
6. Short circuit haibvumirwi zvachose padivi rechipiri revoltage transformer.
