Chinangwa uye nzira yekuyedza ye AC inomira voltage bvunzo yetransformer

Iyo AC inomira voltage bvunzo yetransformer bvunzo umo sinusoidal simba frequency AC bvunzo voltage inodarika imwe yakawanda yeyakayerwa voltage inoiswa kune yakaedzwa transformer inomonereka pamwe chete nebushing, uye nguva i1min.Chinangwa ndechekushandisa test voltage yakakwira kupfuura imwe yakawanda yevoltage yakayerwa kutsiva iyo yemhepo overvoltage uye overvoltage yemukati kuti uongorore kushanda kweiyo insulation yetransformer.Iyo ndiyo nzira inonyanya kushanda yekuziva iyo yekusimbisa simba reshanduko, uye zvakare yakakosha purojekiti yekuyedza kuve nechokwadi chekushanda kwakachengeteka kwetransformer uye kudzivirira kuitika kwetsaona yekudzivirira.Iyo AC inomira voltage bvunzo inogona kuwana iyo main insulation ye transformer yakanyorova uye yakaomeswa hurema, sekupaza kweiyo main insulation ye windings, loose windings Kukanganisa kwakadai sekutamisa, lead insulation daro haina kukwana, uye tsvina yakanamatira kune insulation. .Iyo AC inomira voltage bvunzo bvunzo inoparadza muyedzo yekuisa.Inofanirwa kuitwa mushure meimwe bvunzo dzisiri dzekuparadza (senge insulation kuramba uye absorption ratio bvunzo, DC kuvuza bvunzo, dielectric kurasikirwa kururamisa uye insulating mafuta bvunzo) vanokwanisa..Mushure mokunge muedzo uyu wapfuura, transformer inogona kuiswa mukushanda.Iyo AC inomira nevoltage test ndiyo yakakosha bvunzo, Naizvozvo, yekudzivirira bvunzo mitemo inoti matransformer ane 10kV uye pazasi anofanirwa kuongororwa AC anoshingirira voltage mushure memakore 1 ~ 5, 66kV uye pazasi mushure mekugadzirisa, mushure mekutsiva mamhepo uye kana zvichidikanwa.

Kuedza nzira

(1) Wiring

AC yekunze inomira nevoltage test wiring yemagetsi madiki uye epakati nepakati ari pasi pe35kV.Yese windings inofanira kuongororwa.Panguva yekuyedzwa, waya dzinotungamira dzechikamu chimwe nechimwe chekutenderera dzinofanira kupfupika-kutenderedzwa pamwechete.Kana pane tambo inotungamira panzvimbo isina kwayakarerekera, waya inotungamira inofanirawo kupfupika-yakatenderedzwa nenhatu-phase.

(2) Voltage Testing

Iyo handover test standard inotaridza kuti transformer ine simba riri pazasi pe8000kV uye ine mhepo yakayereswa voltage iri pazasi 110kV inofanirwa kuisirwa AC inomira voltage test zvinoenderana neyeyedzo voltage standard yakanyorwa muAppendix I yechiyero.

Mitemo yekudzivirira yekuyedza inotemerwa: iyo bvunzo voltage kukosha kweoiri-yakanyudzwa matransformer yakatsanangurwa mutafura yemirairo (yenguva dzose bvunzo inotsiva iyo inotenderera voltage kukosha zvinoenderana nechikamu).Kana mhepo dzese dzeiyo yakaoma-mhando transformer inotsiviwa, kukosha kwevoltage yefekitari bvunzo ichashandiswa;apo mahwindi eiyo yakaoma-mhando transformer inotsiviwa zvishoma uye nguva nenguva yakaedzwa, kukosha kwevoltage yefekitari bvunzo ichave 0.85 nguva.
