Chinangwa che transformer AC inomira voltage bvunzo

Munguva yekushanda kwemidziyo yemagetsi, iyo insulation inozoderera zvishoma nezvishoma pasi pekuita kwemunda wemagetsi, tembiricha uye mechanical vibration kwenguva yakareba, kusanganisira kuderera kwese uye kuderera kwechikamu, zvichikonzera kukanganisa.kuremara.

Yakasiyana-siyana yekudzivirira nzira dzekuyedza, imwe neimwe iine masimba ayo, inogona kuwana humwe hurema uye kuratidza mamiriro ekudzivirira, asi magetsi ekuyedza edzimwe nzira dzekuyedza anowanzo kudzika pane yekushanda voltage yemidziyo yemagetsi, asi iyo AC inomira voltage test voltage inowanzoitika. yakakwirira kupfuura iyo yemidziyo yemagetsi.Iko kushanda kwemagetsi kwakakwira, saka mushure mekupasa bvunzo, midziyo ine yakakura chengetedzo margin, saka iyi bvunzo yave nzira yakakosha yekuona kushanda kwakachengeteka.

Nekudaro, sezvo iyo bvunzo voltage inoshandiswa mu AC inomira voltage bvunzo yakakwira zvakanyanya pane yekushanda voltage, yakawandisa voltage inozowedzera kurasikirwa kweiyo insulating medium, kuburitsa kupisa, uye kuburitsa, izvo zvino mhanyisa kusimudzira kwekukanganisa kwekudzivirira.Naizvozvo, neimwe nzira, Iyo AC inomira voltage bvunzo bvunzo inoparadza.Pamberi peiyo AC inomira bvunzo yemagetsi, bvunzo dzakasiyana dzisiri dzekuparadza dzinofanirwa kuitwa pachine nguva.

Zvakadai seyekuyeresa insulation kuramba, absorption reshiyo, dielectric kurasikirwa factor tanδ, DC leakage ikozvino, nezvimwewo, ongorora zvizere mibairo yebvunzo kuti uone kuti mudziyo wacho wakanyorova here kana kuti une hurema.Kana zvikaonekwa kuti pane dambudziko, rinoda kugadziriswa pachine nguva, uye iyo AC inomira voltage bvunzo inogona kuitwa mushure mekunge chirema chabviswa, kuitira kudzivirira kuparara kwekudzivirira panguva ye AC kushingirira bvunzo, kuwedzera insulation. kukanganisa, kuwedzera nguva yekugadzirisa, uye kuwedzera basa rekugadzirisa..

Muedzo uyu unoshandiswa kuona kusimba kwekunze kwekumira kwemutsetse wekugumira uye nekwawakarerekera point terminals uye mahwindi kwaakabatanidzwa kune ivhu uye mamwe mahwindi.Iyo AC inomira voltage bvunzo ndiyo yakatwasuka uye inoshanda nzira yekuyedza simba rekudzivirira re transformer.Inobatsira pakutsvaga zvikanganiso zvepanzvimbo mune main insulation ye transformer, senge iyo huru yekuvharira kwemhepo inonyorova, yakatsemuka kana mhepo yakasununguka panguva yekufambisa, nhanho inotungamira haina kukwana, uye kune mafuta mune main insulation. .Kukanganisa kwakadai sehutsvina, mabhuru emhepo, uye tsvina inonamatira kune inomonereka insulation inoshanda zvakanyanya.Iyo AC inomira bvunzo yemagetsi yetransformer inogona kungoitwa mushure mekunge transformer yazadzwa nemafuta ekuvharisa, inochengetwa yakamira kweimwe nguva yenguva uye mamwe ese ekudzivirira bvunzo anokodzera.

HV HIPOT YDQ yakatevedzana gasi yekuyedza transformer

YDQ yakatevedzana gasi rudzi bvunzo yekushandura inotora zvinhu zvitsva uye tekinoroji nyowani, uye inoshandisa sarufa hexafluoride sepakati.Kuenzaniswa neyechinyakare mafuta-akanyudzwa bvunzo transformer, huremu hwegasi-mhando yekuyedza transformer ingori 40% -80% yeiyo yemafuta-akanyudzwa bvunzo transformer pasi peiyo yakafanana voltage level uye kugona.Iyo voltage level yeimwe unit inogona kusvika 300KV, iyo inonyanya kukodzera kune-saiti mashandiro.Iyo ine maitiro ehukuru hudiki, huremu huremu, haina kusvibiswa kwemafuta, uye haina kukanganiswa nekushanduka kwemamiriro ekunze.Iyo corona idiki zvakanyanya, bvunzo inogona kuitwa pasina kumira panguva yekubata-saiti, uye hupenyu hwesevhisi hwakareba, uye hapana kugadzirisa kunodiwa.

Chigadzirwa zita remadunhurirwa: YDQ AC uye DC SF6 gasi bvunzo mashanduri, gasi-akazadzwa bvunzo mashanduri, akakwira-voltage test transformers, simba repamusoro-voltage test transformers, Ultra-light high-voltage test transformers, cascade high-voltage test transformers, gasi-yakazadzwa test transformers, gas-filled test transformers, gas-filled test transformers, Gas-filled light-duty high-voltage test transformers.
