Ukuze kuthuthukiswe amandla e-insulation, i-coefficient yokulahlekelwa kwe-dielectric nezinye izinkomba zamafutha e-transformer, uwoyela we-transformer kufanele uphathwe ngaphambi kokujova ethangini lamafutha ukuze kukhishwe amanzi, igesi kanye nokungcola emafutheni. Ekusetshenzisweni okungokoqobo, senze ukwelashwa okuhlosiwe kwezinhlobo ezahlukene zamafutha e-transformer, ngemiphumela emihle.

1. Kuwoyela we-transformer ngokuvamile ongcoliswe ukungcola okunjengamanzi nothuli, ipuleti kanye nomshini wokuhlunga uhlaka kungasetshenziswa. Ngemuva kwemijikelezo eminingi yokuhlunga, ingahlangabezana nezidingo. Umgomo wawo uwukusebenzisa iphepha lokuhlunga uwoyela ukumunca amanzi nokuhlunga ukungcola. Ngenxa yesakhiwo sayo esilula nokusingatha kahle, ibuye isetshenziswe kabanzi. Okubi ukuthi ukuhlunga akuphelele, umphumela wokususwa kokungcola okuhle awulungile, futhi izindleko ziphakeme kakhulu. Uma umswakama mkhulu, iphepha lokuhlunga uwoyela lidinga ukushintshwa njalo.

2. Manje isihlungi samafutha e-vacuum sisetshenziswa kabanzi, esingakwazi ukususa ngokuphelele amanzi negesi emafutheni, kodwa futhi sisuse ngokuphumelelayo ukungcola okuncane. Inqubo yokugeleza ithi: uwoyela we-transformer okufanele ulashwe → ukuhlunga okumahhadla → ukuhlunga okuhle → ukukhishwa kwe-vacuum nokukhipha umoya wokushisisa uwoyela → ukuhlanzwa kukawoyela. Isikrini sesihlungi sensimbi kanye nozibuthe onamandla kusetshenziselwa ukuhlunga okumahhadla ukuze kukhishwe ukungcola okungu-1 ~ μ M Trace. Njengamanje, kunezinhlobo eziningi zezihlungi ezinhle, kufaka phakathi izinto ze-sintered metal powder, metal microporous materials, izinto zokuhlunga ze-ceramic kanye nezakhi zokuhlunga ezinezakhiwo ezikhethekile. Idatha evela: inethiwekhi yokudluliswa kwamandla kanye nemishini yokusabalalisa

Amafutha e-transformer ayashisiswa, akhishwe, aphelelwe amanzi futhi akhishwe. Isimiso siwukukhuhla ithange likawoyela bese ufafaza uwoyela we-transformer eshisayo ukuze wenze inkungu kawoyela, ukuze igesi namanzi kuwoyela kubaleke. Izinga lokushisa likawoyela ngokuvamile liba ngu-65 ℃ futhi akufanele libe phezulu kakhulu ukugwema ukuguga kwamafutha. Le ndlela inomphumela omuhle wokukhipha amanzi emzimbeni kanye nokuqeda umoya, futhi okwamanje iyindlela esetshenziswa kakhulu. Kodwa-ke, uma uwoyela ufuthwa enkungwini enhle kakhulu, kulula ukupompa ngepompo yevacuum.

Uma uwoyela ufuthwa emaconsini kawoyela anobubanzi obuthile, umhwamuko wamanzi kumaconsi kawoyela ngeke usetshenziswe ngokugcwele ngenxa yokungezwani okuphezulu kobuso bamaconsi kawoyela. Ngakho-ke, ububanzi bembobo yesifutho kufanele kukhethwe kahle, futhi amanye ama-baffles kufanele abekwe endaweni yokudonsa yethangi likawoyela ukuze kuvinjwe uwoyela we-transformer ukuthi ungampontshwa yiphampu yevacuum.

Njengamanje, izindlela ezithuthukisiwe zokuqeda amanzi emzimbeni kanye nezindlela zokuqeda umoya ziyasetshenziswa ekhaya naphesheya. Ngisho noma uwoyela ongena ethangini wenza ifilimu kawoyela elincanyana ngokwedlulele ngemva kwezakhi ezithile zokuqeda umoya, yonke inqubo yokuqeda amanzi emzimbeni kanye neyokukhipha umoya iqedwa ngenqubo eyodwa yokukhipha amanzi emzimbeni kanye nokukhipha umoya. Isimo sefilimu kawoyela senza kube lula ukususa amanzi negesi emafutheni.

3. Ukwelashwa kwamafutha e-transformer angcolile. Uwoyela we-transformer ongcolile (owaziwa kakhulu ngokuthi uwoyela ongcolile) ubhekisela kuwoyela we-transformer ongcoliswe i-colloid eyakhiwe ngokuhlanganiswa kokungcola okuncane nama-molecule kawoyela, kanye namafutha e-transformer asesetshenziswe iminyaka eminingi. Ngokuvamile, amafutha akhishwa emikhiqizweni yokulungisa (inani le-pH lala mafutha selivele liphansi kakhulu). Lolu hlobo lwamafutha angcolile kufanele luphathwe nge-adsorption ukuze kuthuthukiswe inkomba kawoyela. Ijeli ye-silica (SiO2) noma i-alumina ecushiwe (A12O3) ngokuvamile isetshenziswa njenge-adsorbent. Ohlelweni lokwelapha uwoyela ongcolile, ukuze kuqinisekiswe ukuthintana okugcwele phakathi kwejeli ye-silica namafutha e-transformer futhi kube lula ukushintshwa kwejeli ye-silica, inani lama-diaphragms abekwe ethangini le-silica gel, futhi ijeli ye-silica ifakwa esikhwameni esincane sendwangu. ngezimo eziphuthumayo. Ukuzungezisa, hhayi inqwaba. Amafutha e-transformer ashisayo athunyelwa ethangini likawoyela we-silicone ngomjikelezo othile, ukuze akwazi ukudlala indima yawo ye-adsorption ngokugcwele, abese ejovwa ethangini likawoyela elihlanzekile ngesihlungi sikawoyela. Ukuqapha okuvamile kuzokwenziwa ngesikhathi sokwelashwa ukuze kunqunywe umphumela we-adsorption. Uma umphumela we-adsorption ungabonakali, buyisela ijeli ye-silica. Ngokuvamile, inani lejeli ye-silica libalelwa ku-3% ~ 5% wesisindo sikawoyela. Uhlelo lokuhlanza uwoyela ongcolile luzohlukaniswa ohlelweni olusha lokwelapha uwoyela ukuze kugwenywe ukungcoliswa okuphambene. Ithangi lamafutha kanye nesiqukathi esigcwele uwoyela ongcolile kufanele kuhlanzwe kahle ngaphambi kokukhiqizwa okuvamile ohlelweni lukawoyela.
