I. Chifukwa cha Kutuluka Kwakanthawi

Chotchingira magetsi cha transformer, thupi lachitsulo ndi zina zotero nthawi zambiri chimakhala ndi ngodya yakuthwa ndi burr, kotero magetsi omwe amayendetsedwa ndi mphamvu yamagetsi amakhazikika pamalo akuthwa kapena burr ndipo amachititsa kuti pakhale kutulutsidwa pang'ono.

Epoxy resin yotenthetsera chowuma chotenthetsera mu vacuum casting, ngati kuwongolera bwino njira kungayambitsenso thovu lamkati kenako ndikupanga kutulutsa pang'ono. Nthawi zambiri pamakhala mipata yaying'ono ya mpweya mu epoxy resin insulator, ndipo nthawi zambiri dielectric coefficient ya thovu imakhala yotsika kwambiri kuposa insulator, chifukwa chake, mphamvu yamagetsi ya thovu mu insulator imakhala yayikulu kwambiri kuposa ya zinthu zotenthetsera zomwe zili pafupi, kotero ndikosavuta kufika pamlingo wopambana ndikupanga thovu kukhala lamagetsi poyamba.

Ngati kulumikizana kwa magetsi pakati pa thupi loyendetsa magetsi kuli koipa, zimakhala zosavuta kutulutsa magetsi, zomwe ndizovuta kwambiri pakuyimitsidwa kwachitsulo.

Chinyezi cha mpweya wochuluka, mphamvu ya kutchinjiriza ya gawo la kusinthako sikokwanira, kapena kutchinjiriza kwa transformer kwawonongeka panthawi yoyika, nthawi yosagwira ntchito ya transformer ndi yayitali kwambiri, kuchuluka kwa madzi muzinthu zotchinjiriza kumaposa muyezo, ndipo thupi lonse la transformer ndi lonyowa, zomwe zidzakhudzanso kutuluka pang'ono kwa madzi.

Mphamvu ya zigawo kapena ma turns imakhala yokwera kwambiri popanga kapangidwe ka insulation ya transformer youma, monga kapangidwe ka insulation sikoyenera, zinthu zotetezera kutentha zomwe sizili bwino, mulingo wozungulira, wouma ndi wothira si wabwino, mulingo wa njira yopangira ndi woipa monga kupanga waya wamagetsi okwera komanso otsika ndi ma burrs kapena mtunda wina, zonsezi zidzakhudza kuchuluka kwa kutulutsa kwa gawo.

II. Kuopsa kwa Kutuluka kwa Madzi Pang'ono

Pali mitundu yambiri yotulutsa mpweya pang'ono. Chimodzi ndi mtundu wa kutulutsa mpweya pang'ono komwe kumachitika pamwamba pa chotetezera kutentha. Ngati mphamvuyo ndi yayikulu, chizindikiro cha kutulutsa mpweya chidzalembedwa pamwamba pa chotetezera kutentha ndipo chidzakhudza moyo wa ntchito ya transformer. Palinso mphamvu yayikulu yotulutsa mpweya, yomwe imapezeka mu cavitation kapena electrode yakuthwa, yomwe imayikidwa mu mawonekedwe ochepa otulutsa mpweya pang'ono, yomwe imatha kulowa m'magawo ndi kuya kwa bolodi lotetezera kutentha, ndipo pamapeto pake imabweretsa kuphulika.

Kutulutsa pang'ono ndiye chifukwa chachikulu cha kukalamba ndi kuphulika kwa insulation. Nthawi yochepa yotulutsa sidzayambitsa kuwonongeka kwa dielectric kwa njira yonse, ndipo mphamvu ya electrolytic ya kutulutsa imafulumizitsa kusungunuka kwa insulation, ndikuwononga insulation, kotero moyo wa transformer umachepa. Mlingo wa kuwonongeka umadalira momwe kutulutsa ndi njira yowononga ya insulation yomwe ikutuluka. Ngati kutulutsa pang'ono kwa transformer youma kupitirira mulingo wake wamba, moyo wake wautumiki mkati mwa zaka 3-5 insulation yamkati ikalamba ndi kuphulika kumachitika. Chifukwa chake kutulutsa pang'ono kwa transformer youma kuyenera kulamulidwa mosamala ku China.

III. Kuwongolera Kutulutsa Kwapadera kwa Transformer Youma
Zipangizo zotenthetsera zouma ndi epoxy resin, zotetezeka komanso zodalirika, ndipo zinthu zomwe zili pansi pa 35kV zakhala zikugwiritsidwa ntchito kwambiri. Pali zinthu zambiri zomwe zimakhudza kutulutsa pang'ono kwa transformer youma, zomwe zinthu zazikulu ndi kusankha zipangizo zopangira, kapangidwe ka kapangidwe ka zinthu, njira yopangira zinthu ndi zina zotero. Poganizira za kusintha kwa kapangidwe ka kampani yathu kwa nthawi yayitali, kukonza njira, kusankha zinthu ndi machitidwe opangira, timapereka njira zotsatirazi zowongolera.

1. Kapangidwe ka Kapangidwe ka Ma Winding
(1) Mtunda waukulu wotetezera kutentha, popanga chozungulira cha transformer, uyenera kuwonetsetsa kuti chozungulira chamagetsi chapamwamba ndi chotsika, pakati pa chozungulira chamagetsi chapamwamba, chozungulira chamagetsi chapamwamba pansi chili ndi mtunda wokwanira wotetezera kutentha, pansi pa mkhalidwe wovomerezeka, mtunda wotetezera kutentha ukakhala waukulu, mtunda waukulu mphamvu yamunda imakhala yocheperako. Chozungulira cha khoma mu chozungulira chamagetsi cha HV chikhoza kuwonjezeredwa moyenera kuti chichepetse bwino mphamvu yakunja yamunda.
(2) Kapangidwe ka coil yamagetsi okwera pakati pa zigawo ndi magawo, komwe ndi kuwongolera mphamvu ya munda wa coil, ndipo ngati HV winding ikugwiritsidwa ntchito ndi foil yamkuwa yokhala ndi gawo laling'ono, voltage ya interlayer imafanana ndi voltage ya interturn, nthawi zambiri imangokhala 10 mpaka 20 v, gawo pakati pa zigawo za kapangidwe ka voltage ya waya wamagetsi ndi 400 ~ 800v, ​​nambala ya gawo iyenera kukhala yochulukirapo, monga 35kv dry-type transformer yofunikira nambala ya gawo yoposa zidutswa 16 ~ 18, Zachidziwikire, zimabweretsa mavuto ambiri pa njira yozungulira.
(3) kulamulira chitetezo, kugwiritsa ntchito chitetezo chogwira mtima, kudula m'mphepete, ma burrs ndi mpweya wochepa zitha kupakidwa mkati mwa chishango, zomwe zimatha kuthetsa kutulutsa kwamagetsi kwa nsonga ya ming'alu, ndikuchepetsa kutulutsa pang'ono. Chishango cha HV ndi waya wa HV, LV ndi clamp ziyenera kukhala zodalirika, kukonza chitetezo kuyenera kukhala koyeretsa, zigawo za chishango ziyenera kukhala zosalala, zopanda kusweka ndi nsonga, ndi zina zotero.

2. Kuwongolera Njira Yothira Ma Coil, Kuumba ndi Kuthira Ma Vacuum

Choyira chowuma cha transformer ndicho chofunikira kwambiri, kugwiritsa ntchito choyiracho ndi bwino kapena ayi. Zotsatira za kuthira vacuum ndizofunikanso kwambiri pakutulutsa kwa malo, ngakhale ma pores ang'onoang'ono amakhudza kutulutsa kwa choyiracho m'deralo, kotero njira yopangira ndi kuponyera choyiracho iyenera kulamulidwa mosamala.

(1) tikamapinda coil, tiyenera kudziwa bwino zojambula ndi njira yake, ndipo sitingathe kusintha mwachisawawa kuchuluka kwa ma turn pakati pa zigawo ndi chiwerengero cha mapepala oteteza pakati pa zigawo! Onetsetsani kuti zipangizo zonse ndi zoyera mukapinda.

(2) Mukayika cholumikizira cha nkhungu, samalani ndi kutentha kwambiri, waya wolumikizidwa uyenera kupukutidwa bwino ndi makona ozungulira, ndi zina zotero. Onetsetsani kuti ndodo zonse zatetezedwa kuti zisawonongeke ndi epoxy resin ndikutsukidwa panthawi yonse yopangira. Cholumikizira cha die choyikidwacho chimaumitsidwa motsatira njira yowumitsa.

(3) zosakaniza za epoxy resin ndi degassing, njira yopangira batching iyenera kutsatira mosamalitsa ukadaulo wa code, monga zinthu, chiŵerengero chosakaniza, kutentha ndi nthawi yochotsa gasi, kukhuthala kwa digiriyi kuyenera kutsatira mosamala zomwe zikugwirizana, digiri ya vacuum, kutentha ndi zochitika za thovu, kusakaniza, kutentha ndi digiri ya vacuum kumasunga coil yowonera (mold) mkati mwa kuchuluka kwa kuwongolera kutentha mu ndondomeko yomwe yatchulidwa. Mu ndondomeko yothira, liwiro siliyenera kukhala lachangu kwambiri ndikupanga thovu. Mukathira mwamphamvu, samalani nthawi yomwe zosakanizazo zimathera kuti kukhuthala kwa utomoni kukhale kwakukulu kwambiri.

3. Kusankha ndi kuwongolera zipangizo zopangira

(1) Kusankha waya wamagetsi, mutha kusankha waya wotetezedwa ndi enamel wophimba waya wathyathyathya kapena waya wozungulira wamkuwa; Opereka waya wamagetsi omwe akupanga, ayenera kukhala ndi zida zapadera zochotsera ma burries ndi zida zodziwira, ndikuyesetsa kuchepetsa ma burrs mpaka ochepa.

(2) kusankha zipangizo za epoxy resin, epoxy resin yosiyana, makhalidwe ake ndi osiyana, kutulutsidwa kwa mankhwala m'deralo, komanso magwiridwe antchito ambiri a kugundana ndi abwino kwambiri, ayenera kusankha kukhuthala pang'ono, kulimba bwino, kulimba kwa utomoni, chitsanzo chosiyana cha utomoni, ndi dipatimenti yaukadaulo yopanga specifications zofananira za ndondomekoyi.

(3) kuwongolera zinthu zotetezera kutentha mu coil, ubwino wa zinthu zotetezera kutentha pakati pa zigawo za transformer youma umagwirizana mwachindunji ndi kukula kwa kuchuluka kwa malo. Chifukwa chake, ogulitsa nthawi yayitali komanso okhazikika ayenera kusankhidwa kuti apereke zinthu zopangira, chifukwa mutasintha zinthu zatsopano, transformer singapeze mavuto aliwonse kwakanthawi kochepa.
