Sing'anga yamafuta yosasefedwa imatchedwa mafuta otsika, omwe amakhala ndi madzi ambiri ndi zonyansa, ndipo mphamvu yake ya dielectric imakhala pansi pa 12KV.Makamaka mafuta otsika kwambiri okhala ndi madzi ambiri, ogwiritsa ntchito ena amagwiritsa ntchito makina oyesera mphamvu ya dielectric kuti ayese kuti adziwe momwe zilili zoipa.Zotsatira zake, makina oyesera amphamvu kwambiri a dielectric mphamvu zoyesa mafuta otsekera amawonongeka mosavuta.
Nthawi zambiri, danga pakati pa ma electrode okwera kwambiri amadzaza ndi mafuta oteteza.Pakuyesa, mphamvu yamagetsi pakati pa maelekitirodi awiriwa ikupitilirabe, ndipo zowulutsa zamafuta zomwe zimakhala ndi mphamvu zosiyanasiyana zotsekereza zimatha kupirira minda yamagetsi yamagetsi yamitundu yosiyanasiyana.Mphamvu yamagetsi yokwera kwambiri iyi imapangitsa kuti makina oteteza mafuta awonongeke mwadzidzidzi pomwe sangathe kupirira.Mphamvu yayikulu imasonkhanitsidwa ndi chidacho ndipo nthawi yomweyo imatseka ndikutaya mphamvu yayikulu ndikutembenukira ku ntchito yotsika.
GD6100D Insulation mafuta Tan Delta Tester
Poyesa mafuta abwino kwambiri okhala ndi madzi olemera, mphamvu yamagetsi pakati pa ma elekitirodi a magawo awiri a hemispheres imapitilira kukwera, ndipo nthawi yomweyo, tinthu tating'ono tamadzi mu sing'anga yamafuta timalowetsedwa mumpata pakati pa mipira yomwe imagwira ntchito. magetsi okwera kwambiri kuti apange mzati wamadzi wotumbululuka ngati nkhungu.Kukhuthala, kukana kwa madzi kukucheperachepera.Njira yosakhalitsa iyi yomwe kukana kwamadzi kumakhala kocheperako komanso kuwonjezereka kwa thiransifoma wothamanga kwambiri (popanda kusweka ndi kutulutsa mwadzidzidzi) kumayambitsa kuwonongeka kwa chida, choletsa chotchinga chomwe chilipo, fuseyi idzawotcha, ndipo ngakhale high-voltage transformer ya chidacho idzawotchedwa.

Sing'anga yamafuta yamtunduwu nthawi zambiri imakhala 15 ~ 35KV.Ngakhale malo opangira mafuta atakhala ndi madzi ochepa komanso zonyansa, chidacho chikhoza kuyesabe bwinobwino.Imangosonyeza kuti ena kuwira particles (kapena zosafunika) ndi adsorbed kuti kusiyana pakati pa mipira kupanga kumaliseche pa njira boosting.Mapiritsi a mpweya amathyoledwa ndi kutulutsidwa kuchokera pampata pakati pa mipira, ndipo mafuta amawonjezeredwa, kotero kuti kupanikizika kumapitirirabe mpaka kufika pamtunda waukulu wa sing'anga yamafuta wathyoledwa.Mayeso amtunduwu akadali odalirika.
Kuyesedwa kwa mafuta otsika
Mukabwezeretsanso mafuta opangira mafuta, monga madontho a madzi kapena zonyansa zomwe zingawoneke ndi maso, ndibwino kuti musagwiritse ntchito zida zoyesera.M'malo otsika amafuta omwe asungidwa kwa maola opitilira 24, madontho akulu akulu amamira pansi pa mafutawo, ndipo tinthu tating'ono tating'ono timayandama pamwamba pa mafutawo.Wogwiritsa ntchito ayenera kugwiritsa ntchito ziwiya zopanda madzi kuti atenge mafuta apakati pa gawo lapakati.Pakuyesa, yang'anani mosamala ngati pali nsonga ya nkhungu ngati ulusi wopyapyala monga momwe tawonetsera pa Chithunzi 9 pamene kupanikizika kumawonjezeka (kuyambira pa nthawi yoyamba ya kupanikizika).Zimitsani mphamvu nthawi yomweyo kuti muyimitse mayeso.Kapena ngati pali mfundo zingapo zomwe zimatulutsidwa mosalekeza panthawi yolimbikitsira, chida sichingatseke, ndipo wogwiritsa ntchitoyo azimitsa magetsi ndikuyimitsa mayesowo.
Tsankho la zotsatira za mayeso
Pakuyesa, mphamvu ya spark discharge imasintha muzochitika zinayi:
(1) Mphamvu yachiwiri yotulutsa spark ndiyotsika kwambiri.Mtengo wa mayesowa ukhoza kukhala wotsika chifukwa cha chikoka cha zinthu zina zakunja zomwe zimabweretsedwa ndi chitsanzo cha mafuta mu kapu yamafuta kapena ma electrode odetsedwa a kapu yamafuta musanadzaze mafuta.Panthawiyi, mtengo wapakati wa 2-6 nthawi ukhoza kutengedwa.
(2) Mphamvu yamagetsi ya 6 spark ikukwera pang'onopang'ono, ndipo nthawi zambiri imapezeka mu zitsanzo zamafuta zomwe sizinayeretsedwe kapena kusamalidwa bwino komanso zomwe zamwa chinyezi.Izi ndichifukwa choti mulingo wa chinyontho wa mafutawo umakhala bwino mafuta akatuluka.
(3) Ma voliyumu azinthu zisanu ndi chimodzi zotuluka pang'onopang'ono zimachepa.Nthawi zambiri, zimawonekera mumafuta oyezera, chifukwa tinthu tating'ono tomwe timapangidwa mwaulere, tinthu tating'onoting'ono ta mpweya ndi tchipisi ta kaboni zimawonjezeka motsatizana, zomwe zimawononga magwiridwe antchito amafuta.Kuphatikiza apo, ena oyesa mafuta odziwikiratu sayambitsanso mayeso 6 motsatizana, ndipo ma elekitirodi pakati pa ma elekitirodi The tinthu ta carbon pang'onopang'ono amawonjezeka, zomwe zimapangitsa kuchepa kwapang'onopang'ono kwa voteji yotulutsa.
(4) Mtengo wa spark discharge voltage ndi wotsika kumapeto onse komanso pakati.Izi ndi zachilendo.
Ngati pali kufalikira kwakukulu kwa mtengo wopirira, mwachitsanzo: mu mayesero 6 omwe amachitidwa molingana ndi njira yoyesera yodzitetezera, mtengo wa nthawi imodzi umachoka kuzinthu zina ndi kuchuluka kwakukulu, mtengo wa nthawi ino sungathe kuwerengedwa. , kapena kuyesa kwa mafuta kudzatengedwanso.Nthawi zambiri zimayamba chifukwa cha mafuta osakwanira kapena kugawa kosagwirizana kwa kaboni waulere.
Chifukwa cha kubalalitsidwa kwakukulu kwamafuta kupirira zotsatira za mayeso amagetsi, ngati voteji yakuwonongeka ndiyokwera kwambiri (pafupi ndi 80KV) kapena zotsatira zake zimakhala zofanana nthawi zonse, zikutanthauza kuti chida chikhoza kuwonongeka, chonde lemberani wopanga.
