I. Imbangela Yokukhishwa Kwegazi Okungaphelele

Isivikelo se-transformer, umzimba wensimbi njalonjalo kuvame ukuba ne-engeli ebukhali kanye ne-burr, ngakho-ke amashaji kagesi ngaphansi kwesenzo sokuqina kwensimu kagesi azogxila endaweni ye-engeli ebukhali noma ye-burr futhi abangele ukukhishwa okuyingxenye.

I-epoxy resin efakwe i-transformer eyomile efakwe i-vacuum casting, uma ukulawulwa kwenqubo okungekuhle kuzobangela amabhamuza angaphakathi bese kukhiqiza ukukhishwa okungaphelele. Ngokuvamile kunezikhala ezincane zomoya ku-epoxy resin insulator, futhi ngokuvamile i-dielectric coefficient yamabhamuza iphansi kakhulu kune-insulator, ngenxa yalokho, amandla kagesi ebhamuza ku-insulator aphezulu kakhulu kunalawo ezinto ezivikelayo eziseduze, ngakho-ke kulula ukufinyelela izinga lokuphumelela nokwenza amabhamuza akhishwe ngogesi kuqala.

Uma uxhumano lukagesi phakathi komzimba oqhubayo lungalungile, kulula ukukhipha ugesi, okuyinto embi kakhulu emandleni okumiswa kwensimbi.

Umswakama womoya osindayo, amandla okuvikela ingxenye yokuguqulwa akwanele, noma ukuvikela i-transformer konakele ngesikhathi sokufakwa, isikhathi sokusebenza se-transformer side kakhulu, okuqukethwe kwamanzi kwezinto zokuvikela kudlula izinga, futhi wonke umzimba we-transformer umanzi, okuzothinta nokukhishwa kwengxenye.

Amandla agciniwe ezingqimba noma amajika aphezulu kakhulu lapho kuklanywa isakhiwo sokushisa sokuguqula okomile, njengokwakhiwa kwesakhiwo sokushisa akunangqondo, izinto zokushisa ezisezingeni eliphansi, izinga lokugoqa, ukomisa kanye nenqubo yokuthulula alilihle, izinga lenqubo yokuhlanganisa alilihle njengokukhiqizwa kwentambo ye-lead ephezulu nephansi ene-burrs noma ibanga elithile, konke kuzothinta ukukhishwa okuyingxenye ukuze kwande.

II. Ingozi Yokuphuma Kwegazi Okungaphelele

Kunezinhlobo eziningi zokukhishwa okungaphelele. Olunye uhlobo lokukhishwa okungaphelele okwenzeka endaweni yokuvikela umswakama. Uma amandla emakhulu, umkhondo wokukhishwa uzobekwa uphawu ebusweni bokuvikela umswakama futhi uzothinta impilo yesevisi ye-transformer. Kukhona futhi ukuqina kokukhishwa okuphezulu, okwenzeka ku-cavitation noma i-electrode ebukhali, egxile efomini lokukhishwa okungaphelele okumbalwa okukhipha okubolayo, okungangena ezingqimbeni nasekujuleni kwebhodi lokuvikela umswakama, futhi ekugcineni kuholele ekuthuthukisweni.

Ukukhishwa kwengxenye kuyimbangela eyinhloko yokuguga nokuqhuma kwe-insulation. Isikhathi esifushane sokukhishwa ngeke sibangele umonakalo we-dielectric wesiteshi sonke, futhi isenzo se-electrolytic sokukhishwa kwe-insulation sisheshisa i-oxidation ye-insulation, futhi sigqwalise ukuvalwa kwe-insulation, ngakho-ke impilo ye-transformer iyancipha. Izinga lomonakalo lincike ekusebenzeni kokukhishwa kanye nendlela yomonakalo ye-insulation ngaphansi kokukhishwa. Uma ukukhishwa kwengxenye ye-transformer eyomile kudlula kakhulu izinga layo elijwayelekile, impilo yayo yenkonzo eminyakeni emi-3 kuya kwemi-5 ukuguga nokuqhuma kwe-insulation yangaphakathi kuzokwenzeka. Ngakho-ke ukukhishwa kwengxenye ye-transformer eyomile kufanele kulawulwe ngokuqinile eShayina.

III. Ukulawulwa Kokukhishwa Okungaphelele Kwesiguquli Esomile
Izinto zokufakelwa eziyinhloko ze-transformer ezomile ziyi-epoxy resin, ziphephile futhi zithembekile, ohlelweni lwamandla imikhiqizo engaphansi kuka-35kV isetshenziswe kabanzi. Kunezici eziningi ezithinta ukukhishwa kwengxenye ye-transformer eyomile, phakathi kwazo izici eziyinhloko ukukhetha izinto zokusetshenziswa, ukwakheka kwesakhiwo somkhiqizo, inqubo yokugaya njalonjalo. Ngenxa yokulungiswa komklamo wenkampani yethu isikhathi eside, ukuthuthukiswa kwenqubo, ukukhethwa kwezinto kanye nomkhuba wokukhiqiza, sinikeza izinyathelo zokulawula ezilandelayo.

1. Umklamo Wesakhiwo Esijikelezayo
(1) Ibanga eliyinhloko lokufakwa kokushisa, ekwakhiweni kwe-transformer winding, kufanele liqinisekise ukuthi ikhoyili ye-voltage ephezulu nephansi, phakathi kwekhoyili ye-voltage ephezulu, ikhoyili ye-voltage ephezulu eya phansi inebanga elanele lokufakwa kokushisa, ngaphansi kwesimo esivumelekile, ibanga lokufakwa kokushisa likhulu, ibanga elikhulu namandla ensimu lincane. Ukufakwa kokushisa odongeni kukhoyili ye-HV kungandiswa ngokufanele ukuze kuncishiswe ngempumelelo amandla ensimu yangaphandle.
(2) Umklamo wekhoyili ye-voltage ephezulu phakathi kwezingqimba nezingxenye, okuwukulawula amandla ensimu yekhoyili, futhi uma kusetshenziswa i-HV winding nge-foil yethusi ene-subsection, i-voltage ye-intersection ilingana ne-interturn voltage, ngokuvamile kuphela ku-10 kuya ku-20 v, isigaba phakathi kwezingqimba zesakhiwo se-voltage ye-electromagnetic wire ingu-400 ~ 800v, ​​inombolo yesigaba kufanele ibe ngaphezulu, njenge-transformer yohlobo olomile engu-35kv inombolo yesigaba efiselekayo engaphezu kwezingcezu ezingu-16~18, Yiqiniso, kuletha izinkinga eziningi enqubweni ye-winder.
(3) ukulawula ukuvikela, ukusebenzisa ukuvikela okusebenzayo, imiphetho yokusika, ama-burrs kanye negebe lomoya kungapakishwa ngaphakathi kwesihlangu, okungaqeda ngempumelelo ukukhishwa kukagesi kwesihloko sokuqhekeka, futhi kunciphise ukukhishwa okuyingxenye. Isihlangu se-HV kanye nesiphelo sentambo ye-HV, i-LV kanye ne-clamp kufanele kube ukuxhumana okuthembekile, ukucubungula ukuvikela kufanele kuhlale kuhlanzwa, izendlalelo zesihlangu kufanele zibe bushelelezi, zingaphuki futhi zibe mfushane, njll.

2. Ukulawula Inqubo Yokugoqa Amakhoyili, Ukubumba kanye Nokuthulula I-Vacuum

Ikhoyili ye-transformer eyomile iyona ebaluleke kakhulu, ukusetshenziswa kwe-transformer kuhle noma cha ukwehluleka kwekhoyili. Umphumela wokuthululwa kwe-vacuum ubaluleke kakhulu ekukhululweni kwendawo, ngisho nezimbobo ezincane zithinta ukukhululwa kwendawo kwe-transformer, ngakho-ke inqubo yokukhiqiza nokuphonswa kwekhoyili kumele ilawulwe ngokuqinile.

(1) lapho sigoqa ikhoyili, kumelwe sijwayelane nemidwebo kanye nenqubo, futhi asikwazi ukushintsha ngokunganaki inani lokujika phakathi kwezingqimba kanye nenani lamashidi okuvikela phakathi kwezingqimba! Qiniseka ukuthi zonke izinto zihlanzekile lapho sigoqa.

(2) Uma ufaka ukushisela kwe-mold lead terminal, qaphela umonakalo oshisayo we-coil insulation, intambo eshisiwe kumele ipholishwe nge-sharp corner burr, njll. Qinisekisa ukuthi wonke ama-lead afakwe i-insulation ebangeni elanele ukuze agcwaliswe nge-epoxy resin futhi ahlanzwe kuyo yonke inqubo yokuhlanganisa. I-die coil efakiwe yomiswa ngokuqinile ngokuhambisana nenqubo yokomisa.

(3) izithako ze-epoxy resin kanye ne-degassing, inqubo yokuhlanganisa kufanele ihambisane ngokuqinile nobuchwepheshe bekhodi, njengezinto ezibonakalayo, isilinganiso sokuxuba, izinga lokushisa kanye nesikhathi sokukhipha igesi, i-viscosity yezinga kufanele ilandelele eduze izinga le-vacuum, izinga lokushisa kanye ne-bubble, ukuxuba, izinga lokushisa kanye ne-vacuum degree kugcina i-observation coil (isikhunta) ngaphakathi kobubanzi bokulawula izinga lokushisa enkambisweni ecacisiwe. Enkambisweni yokuthulula, ijubane akufanele libe lishesha kakhulu futhi likhiqize amabhamuza. Lapho kuthululwa ngokuguquguqukayo, kufanele kuqashelwe isikhathi ngemva kokuqeda ukuthulula izithako ukuze kuvinjelwe i-viscosity ye-resin inkulu kakhulu.

3. Ukukhethwa nokulawulwa kwezinto zokusetshenziswa

(1) Ukukhetha ucingo lwe-electromagnetic, kungakhetha ukubopha umklamo we-enamel wire insulation flat copper noma i-round copper wire; abahlinzeki be-electromagnetic wire abakhiqizwayo, kumele babe nemishini ekhethekile yokususa ukubhoboza kanye namadivayisi okuthola, futhi balwele ukunciphisa ama-burrs abe mancane kakhulu.

(2) ukukhetha izinto ze-epoxy resin, i-epoxy resin ehlukene, izici zayo zihlukile, ukukhishwa kwendawo komkhiqizo, ukusebenza okuphelele komthelela nakho kuhle kakhulu, kufanele ukhethe i-viscosity encane, ukuqina okuhle, amandla aphezulu okushisa kwe-resin, imodeli ehlukile ye-resin, umnyango wezobuchwepheshe ukuthuthukisa imininingwane yenqubo ehambisanayo.

(3) ukulawulwa kwezinto zokufaka ugesi kukhoyili, ikhwalithi yezinto zokufaka ugesi phakathi kwezingqimba ze-transformer eyomile ihlobene ngqo nosayizi wenani lendawo. Ngakho-ke, abahlinzeki besikhathi eside nabazinzile kufanele bakhethwe ukuhlinzeka ngezinto zokusetshenziswa, ngoba ngemva kokushintsha izinto ezintsha, i-transformer ayikwazi ukuthola izinkinga esikhathini esifushane.
