I. Isizathu sokukhupha i-Paralymal

Isigqubuthelo se-transformer, umzimba wesinyithi njalo njalo zihlala zine-engile ebukhali kunye ne-burr, ngoko ke iitshaja zombane phantsi kwesenzo sokuqina kwentsimi yombane ziya kugxila kwindawo ye-engile ebukhali okanye ye-burr kwaye zibangele ukukhutshwa okungaphelelanga.

I-epoxy resin egqunywe yitransformer eyomileyo kwi-vacuum casting, ukuba ulawulo olubi lwenkqubo luya kubangela amaqamza angaphakathi aze emva koko avelise ukukhupha okungaphelelanga. Ngokubanzi kukho izithuba ezincinci zomoya kwi-epoxy resin insulator, kwaye ngokuqhelekileyo i-dielectric coefficient yamaqamza iphantsi kakhulu kune-insulator, ngenxa yoko, amandla ombane eqamza kwi-insulator aphezulu kakhulu kunowezinto ezikhuselayo ezikufutshane, ngoko ke kulula ukufikelela kwinqanaba lokuphumelela kwaye wenze amaqamza akhuphe ngombane kuqala.

Ukuba unxibelelwano lombane phakathi komzimba oqhuba umbane alulunganga, kulula ukuvelisa ukukhupha umbane, okuyeyona nto inzima kakhulu kwi-metal suspension potential.

Umswakama womoya onzima, amandla obushushu enxalenye yotshintsho awanelanga, okanye ubushushu be-transformer buyayonakala ngexesha lokufakwa, ixesha lokungasebenzi kwe-transformer lide kakhulu, umxholo wamanzi wezinto zobushushu udlula umgangatho, kwaye umzimba wonke we-transformer umanzi, nto leyo eya kuchaphazela nokukhutshwa okungaphelelanga.

Amandla agciniweyo eeleya okanye amajika aphezulu kakhulu xa kuyilwa isakhiwo sokufakelwa kwe-transformer esomileyo, njengoyilo lwesakhiwo sokufakelwa kwe-insulation alunangqiqo, izixhobo zokufakelwa kwe-insulation ezikumgangatho ophantsi, inqanaba lenkqubo yokujika, ukomisa kunye nokuthulula alilungile, inqanaba lenkqubo yokuhlanganisa alilunganga njengokuveliswa kwentambo ye-voltage ephezulu nephantsi ene-burrs okanye umgama othile, konke oku kuya kuchaphazela ukwanda kokukhutshwa okungaphelelanga.

II. Ingozi Yokukhupha Igazi Ngokungaphelelanga

Kukho iintlobo ezininzi zokukhupha okungaphelelanga. Olunye luhlobo lokukhupha okungaphelelanga okwenzeka kumphezulu wokukhusela. Ukuba amandla makhulu, umkhondo wokukhupha uya kuphawulwa kumphezulu wokukhusela kwaye uya kuchaphazela ubomi benkonzo ye-transformer. Kukwakho nobunzima bokukhupha obuphezulu, obenzeka kwi-cavitation okanye kwi-electrode ebukhali, egxininiswe kwifom yokukhupha okungaphelelanga okumbalwa kokukhupha okubolayo, okunokungena kwiileya kunye nobunzulu bebhodi yokukhusela, kwaye ekugqibeleni kukhokelele ekuphuhlisweni.

Ukukhupha inxalenye yento eyona nto ibangela ukuguga nokuphumelela kwe-insulation. Ixesha elifutshane lokukhupha aliyi kubangela umonakalo we-dielectric wetshaneli yonke, kwaye isenzo se-electrolytic sokukhupha sikhawulezisa i-oxidation ye-insulation, kwaye sichitha i-insulation, ngoko ke ubomi be-transformer buyancipha. Ubungakanani bomonakalo buxhomekeke ekusebenzeni kokukhupha kunye nendlela yomonakalo ye-insulation phantsi kokukhupha. Ukuba ukukhupha inxalenye ye-transformer eyomileyo kudlula kakhulu kwinqanaba layo eliqhelekileyo, ubomi bayo benkonzo kwiminyaka emi-3 ukuya kweyesi-5 yokuguga kunye nokuphumelela kwe-insulation yangaphakathi kuya kwenzeka. Ngoko ke ukukhupha inxalenye ye-transformer eyomileyo kufuneka kulawulwe ngokungqongqo eTshayina.

III. Ulawulo lokukhupha umbane oluyi-Dry Transformer
Izinto eziphambili zokwambathisa ezisetyenziswa kwi-transformer eyomileyo zizinto ze-epoxy resin, zikhuselekile kwaye zithembekile, kwinkqubo yamandla engaphantsi kwe-35kV iimveliso zisetyenziswa kakhulu. Kukho izinto ezininzi ezichaphazela ukukhutshwa okungaphelelanga kwe-transformer eyomileyo, phakathi kwazo izinto eziphambili kukukhetha izinto ezikrwada, uyilo lwesakhiwo semveliso, inkqubo yokusika ngokujika njalo njalo. Ngenxa yohlengahlengiso loyilo lwenkampani yethu lwexesha elide, ukuphuculwa kwenkqubo, ukukhethwa kwezinto kunye nokuziqhelanisa nemveliso, misela amanyathelo olawulo alandelayo.

1. Uyilo lweSakhiwo esijikelezayo
(1) Umgama ophambili wokufakelwa kwe-insulation, kuyilo lwe-transformer winding, kufuneka uqinisekise ukuba ikhoyili ye-voltage ephezulu nephantsi, phakathi kwekhoyili ye-voltage ephezulu, ikhoyili ye-voltage ephezulu emhlabeni inomgama owaneleyo wokufakelwa kwe-insulation, phantsi kwemeko evumelekileyo, umgama omkhulu wokufakelwa kwe-insulation, kokukhona umgama omkhulu amandla entsimi emancinci. Ukufakelwa kwe-insulation eludongeni kwikhoyili ye-HV kunokwandiswa ngokufanelekileyo ukuze kuncitshiswe ngempumelelo amandla entsimi yangaphandle.
(2) Uyilo lwekhoyili yombane ophezulu phakathi kweeleya kunye namacandelo, olulawula amandla entsimi yekhoyili, kwaye ukuba i-HV winding isetyenziswa ngefoyile yobhedu enecandelo elincinci, i-voltage ye-interlayer ilingana ne-interturn voltage, ngokubanzi ifikelela kwi-10 ukuya kwi-20 v kuphela, icandelo phakathi kweeleya zesakhiwo se-voltage yombane we-electromagnetic yi-400 ~ 800v, ​​inombolo yecandelo kufuneka ibe ngaphezulu, njenge-35kv yohlobo olomileyo i-transformer inombolo yecandelo efunekayo ngaphezulu kwee-16 ~ 18 iziqwenga, Kakade ke, izisa ingxaki enkulu kwinkqubo ye-winder.
(3) ulawulo lokukhusela, ukusebenzisa ukhuselo olusebenzayo, imiphetho yokusika, ii-burrs kunye nomsantsa womoya zinokupakishwa ngaphakathi kwekhaka, nto leyo enokuphelisa ngempumelelo ukukhutshwa kombane kwincam yokuqhekeka, kwaye inciphise ukukhutshwa okungaphelelanga. Isikhuselo se-HV kunye nesiphelo sentambo ye-HV, i-LV kunye ne-clamp kufuneka ziqhagamshele ngokuthembekileyo, ukucubungula ukhuseleko kufuneka kuhlale kucocekile, iileya zesikhuselo kufuneka zibe bushelelezi, zingaphuki kwaye ziqhekeke, njl.

2. Ulawulo lweNkqubo yokuQokelela, ukuBumba kunye nokuThulula iVacuum

I-coil ye-transformer eyomileyo yeyona ibaluleke kakhulu, ukusetyenziswa kwe-transformer kulungile okanye akunjalo ukusilela kwe-coil. Isiphumo sokuthululwa kwe-vacuum sibaluleke kakhulu ekukhutshweni kwendawo, nokuba ii-pores ezincinci zichaphazela ukukhululwa kwendawo ye-transformer, ngoko ke inkqubo yokuvelisa kunye nokuphoswa kwe-coil kufuneka ilawulwe ngokungqongqo.

(1) xa sibhida ikhoyili, kufuneka siqhelane nemizobo kunye nenkqubo, kwaye asinakutshintsha ngokungakhethiyo inani lokujika phakathi kweeleya kunye nenani lamashiti okukhusela phakathi kweeleya! Qinisekisa ukuba zonke izinto zicocekile xa zibhida.

(2) Xa ufaka i-mold lead terminal welding, qaphela umonakalo obangelwa kubushushu obuphezulu kwi-coil insulation, ucingo oludibeneyo kufuneka lupholishwe nge-sharp corner burr, njl. Qinisekisa ukuba zonke i-leads zigqunywe kumgama owaneleyo ukuze zizaliswe yi-epoxy resin kwaye zicoceke kuyo yonke inkqubo yokuhlanganisa. I-die coil efakiweyo yomiswa ngokungqongqo ngokuhambelana nenkqubo yokomisa.

(3) izithako ze-epoxy resin kunye ne-degassing, inkqubo yokudibanisa kufuneka ilandele ngokungqongqo iteknoloji yekhowudi, efana nezinto, umlinganiselo wokuxuba, ubushushu kunye nexesha lokukhupha igesi, i-viscosity ye-degree kufuneka ilandelele ngokusondeleyo i-vacuum degree, i-vacuum degree, i-temperature kunye ne-bubble phenomenon, ukuxuba, ubushushu bokuthulula kunye ne-vacuum degree kugcina i-observation coil (mould) ngaphakathi kobubanzi bolawulo lobushushu kwinkqubo echaziweyo. Kwinkqubo yokuthulula, isantya akufuneki sikhawuleze kakhulu kwaye sivelise amaqamza. Xa kuthululwa ngokuguquguqukayo, kufuneka kuqwalaselwe ixesha emva kokuba izithako zigqityiwe ukuthululwa ukuze kuthintelwe ukuba i-resin viscosity inkulu kakhulu.

3. Ukukhethwa nokulawulwa kwezinto ezikrwada

(1) Ukukhetha ucingo lwe-electromagnetic, unokukhetha i-enamel wire insulation flat copper okanye i-round copper wire winding; Ababoneleli be-electromagnetic wire abakwimveliso, kufuneka babe nezixhobo ezikhethekileyo zokususa iimbumbulu kunye nezixhobo zokufumanisa, kwaye bazame ukunciphisa iimbumbulu zibe zincinci.

(2) ukhetho lwezixhobo ze-epoxy resin, i-epoxy resin eyahlukeneyo, iimpawu zayo zahlukile, ukukhululwa kwemveliso kwindawo, ukusebenza okubanzi kwempembelelo nako kukhulu, kufuneka ukhethe i-viscosity encinci, ubulukhuni obuhle, amandla aphezulu okugquma kwe-resin, imodeli eyahlukeneyo ye-resin, icandelo lobugcisa lokuphuhlisa iinkcukacha zenkqubo ehambelanayo.

(3) ulawulo lwezinto zokwambathisa kwikhoyili, umgangatho wezinto zokwambathisa phakathi kweengqimba zetransformer eyomileyo unxulumene ngokuthe ngqo nobukhulu bexabiso lendawo. Ke ngoko, ababoneleli bexesha elide nabazinzileyo kufuneka bakhethwe ukuba banikezele ngezinto zokwenza imveliso, kuba emva kokutshintsha izinto ezintsha, itransformer ayinakufumana ngxaki kwixesha elifutshane.
