Mamiriro Ekushandisa
1. Ambient tembiricha: -25℃～+40℃;
2. Chiyero chekusvibiswa: Ⅳ nhanho;
3. Teerera neGBl207-2006 "Voltage Transformer" chiyero.
Principle
Kana iyo voltage transformer iri mukushanda kwakajairika, matatu-phase voltage yesimba remagetsi inoenzanirana, uye huwandu hwematatu-chikamu induced electromotive simba pane yechitatu coil i zero.Kana iyo imwe-phase grounding ikaitika, iyo isina kwayakarerekera poindi ichabviswa, uye zero-sequence voltage ichaonekwa pakati pematerminal yeakavhurika katatu kuita relay kuita, nekudaro kuchengetedza simba system.Kana zero-sequence voltage ichionekwa mucoil, zero-sequence magineti flux inozoonekwa mune inoenderana iron core.Kuti izvi zviitike, iyi matatu-phase voltage transformer inotora rutivi rwejoko musimboti (kana 10KV uye pazasi) kana matatu single-phase voltage transformers.Kune rudzi urwu rwetransformer, kurongeka kwekoiri yechitatu hakuna kukwirira, asi kunoda humwe hunhu hwekuwedzeredza (kureva kuti, kana iyo yekutanga voltage ichiwedzera, iyo magineti flux density musimbi core inowedzerawo neinoenderana yakawanda isina kukuvara).
Sei uchifanira kushandura voltage pamutsara?Izvi zvinodaro nekuti zvinoenderana nemamiriro akasiyana ekugadzira magetsi, kutapurirana uye kushandiswa kwemagetsi, ma voltages pamitsara akasiyana muhukuru, uye mutsauko wakasiyana zvakanyanya.Mamwe ari low-voltage 220V uye 380V, uye mamwe ane high-voltage makumi ezviuru zvevolts kana kunyange mazana ezviuru zvevolts.Kuti uenzanise zvakananga idzi low-voltage uye high-voltage voltages, zvinodikanwa kuita zvinoenderana ne-low-voltage uye high-voltage voltmeters nezvimwe zviridzwa uye relays maererano nehukuru hwemagetsi emutsara.Izvi hazvizongounza matambudziko makuru pakugadzirwa kwechiridzwa, asi chinonyanya kukosha, hazvibviri uye zvachose zvinorambidzwa kuita zvakananga chigadzirwa chepamusoro-voltage uye kuyera magetsi zvakananga pamutsara we-high-voltage.
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.
