Iyo yakadzoserwa isina kusefa yeoiri yepakati inonzi yakaderera mafuta, iyo ine yakawanda yemvura uye tsvina, uye simba rayo re dielectric rinonyanya pasi pe12KV.Kunyanya kumafuta akaderera ane mvura yakawanda, vamwe vashandisi vanoshandisa high-dielectric simba tester kuti vaedze kuti vazive kuti yakaipa sei.Nekuda kweizvozvo, iyo yakakwira-voltage test system ye dielectric simba tester yemafuta ekuvharisa inokuvara nyore.
Kazhinji, nzvimbo iri pakati peiyo high voltage electrode inozadzwa nemafuta anodzivirira.Panguva yekuyedzwa, voltage iri pakati pemaelectrode maviri inoramba ichiwedzera, uye midhiya yemafuta ine masimba akasiyana ekudzivirira inogona kumirisana nemagetsi emagetsi emhando dzakasiyana.Iyi nzvimbo yemagetsi yakakwira-voltage inokwira inoita kuti iyo insulating oil media ivhunike kamwe kamwe kana isingakwanise kuimirira.Ikozvino huru inounganidzwa nechiridzwa uye pakarepo inovhara uye inorasikirwa nepamusoro-soro uye inoshandura kutsika-pasi kushanda.
GD6100D Insulation mafuta Tan Delta Tester
Paunenge uchiyedza mafuta asina kunaka ane mvura inorema, voltage iri pakati pemaelectrodes ehemispheres mbiri inoramba ichikwira, uye panguva imwe chete, zvimedu zvemvura zviri mukati meoiri zvinopinzwa mugomba riri pakati pemabhora pasi pechiito che high-voltage electric field kuti iite mhute yakachena yakaita semvura.Yakakobvuka, kusamira kwemvura kuri kuita kudiki nekudiki.Iyi nzira yenguva pfupi iyo inodzivirira mvura inova diki uye ikozvino yeakakwira-voltage transformer inowedzera (pasina kuparara uye nekukasira kubuda) ichakonzera kukuvadza kune chiridzwa, chazvino chinomisa chinodzivirira, fuse ichapisa, uye kunyangwe iyo high-voltage transformer yechiridzwa ichapiswa.
Muedzo we low pressure oil medium
Rudzi urwu rwepakati pemafuta kazhinji pa15 ~ 35KV.Kunyangwe iyo svikiro yemafuta iine mvura shoma uye tsvina, chiridzwa chinogona kuramba chichiyedza.Zvinongoratidza kuti mamwe mabubble particles (kana tsvina) anoshambadzirwa kune gaka riri pakati pemabhora kuti abudise kubuda panguva yekusimudzira maitiro.Mhepo yemhepo inoputika uye inobudiswa kubva pakakoromo pakati pemabhora, uye mafuta anozadzikiswa, saka kudzvinyirira kunoramba kuchiwedzera kusvikira iyo yepamusoro inotakura nzvimbo yemafuta yepakati yaputsika.Rudzi urwu rwe data rekuyedza richiri kuvimbika.
Muedzo wemafuta akaderera
Paunenge uchidzoreredza svikiro remafuta kuti riseferwe, senge madonhwe emvura kana tsvina inogona kuoneka neziso rakashama, zviri nani kuti usashandise zvine simba midziyo yekuyedza.Muchidimbu chemafuta chepasi chave chakachengetwa kweanopfuura maawa makumi maviri nemana, madonhwe makuru emvura anonyura pasi peoiri, uye maturu akatsetseka anoyangarara pamusoro pemafuta.Mushandisi anofanira kushandisa midziyo isina-mvura-yakasvibiswa kuti abudise sampu yeoiri pakati pepakati.Panguva yekuedzwa, nyatsocherechedza kana paine mhute yakaita seshinda yakatetepa sezvakaratidzwa mumufananidzo 9 apo kudzvinyirira kunowedzera (kutangira kubva panguva yekutanga yekuwedzera kwekumanikidza).Dzima simba nekukurumidza kuti umise bvunzo.Kana kana paine akawanda mapoinzi ekuramba achiburitsa panguva yekusimudzira, chiridzwa hachigone kudzima otomatiki, uye mushandisi anofanira kudzima magetsi nekumisa bvunzo.
Kusarura kwemhinduro dzebvunzo
Muyedzo, iyo spark discharge voltage inoshanduka mumamiriro mana:
(1) Iyo yechipiri spark discharge voltage yakadzikira zvakanyanya.Kukosha kwemuedzo uyu kunogona kuve kwakaderera nekuda kwesimba rezvimwe zvinhu zvekunze zvinounzwa nesampu yemafuta mukapu yemafuta kana iyo isina kuchena electrode pamusoro pekapu yemafuta isati yazara mafuta.Panguva ino, chiyero chepakati che 2-6 nguva chinogona kutorwa.
(2) Kukosha kwevoltage yezvitanhatu spark zvinobuda zvishoma nezvishoma, uye zvinowanzoitika mumasampuli emafuta asina kucheneswa kana kunyatsorapwa uye atora hunyoro.Izvi zvinodaro nekuti hunyoro hwemafuta hunovandudzwa mushure mekunge mafuta aburitswa.
(3) Huwandu hwemagetsi ezvitanhatu spark zvinobuda zvishoma nezvishoma.Kazhinji, inoonekwa mumafuta akachena ebvunzo, nekuti iyo inogadzirwa yemahara yakachajwa zvimedu, mabhuru emhepo uye kabhoni machipisi anowedzera zvakateerana, izvo zvinokanganisa kushanda kwemafuta.Uye zvakare, mamwe maotomatiki emafuta anoedza haazunguze panguva ye6 inoteedzana bvunzo, uye ma electrode pakati pee electrode Iyo kabhoni particles zvishoma nezvishoma inowedzera, zvichikonzera kuderera zvishoma nezvishoma mu spark discharge voltage.
(4) Iyo spark discharge voltage value yakaderera kumativi ese uye yakakwira pakati.Izvi zvakajairika.
Kana paine kupararira kwakakura kwekumira kwevoltage kukosha, semuenzaniso: mune 6 bvunzo dzakaitwa maererano nekudzivirira bvunzo nzira, kukosha kweimwe nguva kunotsauka kubva kune mamwe maitiro nehuwandu hukuru, kukosha kwenguva ino hakugone kuverengerwa. , kana bvunzo yemafuta inotorwa zvakare.Zvingangodaro zvinokonzerwa nehusina kunaka hwemafuta kana kugovera kusina kuenzana kwekabhoni yemahara.
Nekuda kwekupararira kukuru kwemafuta anomira nevoltage test mhinduro, kana magetsi ekuparara akanyanya kukwira (pedyo ne80KV) kana mhedzisiro yakafanana nguva dzese, zvinoreva kuti chiridzwa chinogona kukuvara, ndapota taura nemugadziri.
