Chosinthira kutentha (potting transformer) chili ndi ntchito yokhazikitsa kutentha, chimathandizira kuyambitsa ndi kutseka mafani pogwiritsa ntchito manja/okha, komanso chili ndi ntchito zotumiza cholakwika, alamu yomveka komanso yowoneka bwino pa kutentha kwambiri, ulendo wodziyimira pawokha pa kutentha kwambiri, ndi zina zotero. Zachidziwikire, mawonekedwe a chosinthira kutentha ndi ochulukirapo kuposa pamenepo. Gawo lotsatirali likupatsani chiyambi chatsatanetsatane. Tiyeni tipitirize kuyang'ana:
1. Ili ndi magwiridwe antchito abwino komanso mphamvu yochepa yotulutsa mpweya. Chifukwa cha kapangidwe kake kapadera komanso ukadaulo wapamwamba wopanga zinthu, transformer yomwe ili mkati mwake ili ndi mphamvu yochepa yotulutsa mpweya.
2. Ili ndi mphamvu yolimbana ndi mphezi. Chifukwa chakuti ma windings okwera ndi otsika amagetsi onse amalumikizidwa ndi tepi yamkuwa (foil), mphamvu ya interlayer ndi yochepa, mphamvu yake ndi yayikulu, ndipo kugawa kwa mphamvu yoyambirira ya foil winding kuli pafupi ndi mzere, imakhala ndi mphamvu yolimbana ndi mphezi.
3. Ili ndi kukana kwamphamvu kwa ma circuit afupi. Chifukwa ma windings okwera ndi otsika ali ndi kutalika kofanana kwa reactance popanda ngodya yozungulira, ma ampere turns pakati pa ma coils ndi ofanana, ndipo mphamvu ya axial yomwe imabwera chifukwa cha ma windings okwera ndi otsika amagetsi imakhala pafupifupi zero, ili ndi kukana kwamphamvu kwa ma circuit afupi.
4. Kagwiridwe kake koletsa kusweka ndi kabwino. Transformer yolumikizidwa imagwiritsa ntchito "ukadaulo wothina woteteza kusweka" wa epoxy resin, womwe umakwaniritsa zofunikira za kutentha kochepa, kutentha kwambiri komanso kutentha kwakukulu, umakwaniritsa zofunikira zoletsa kusweka pambuyo pakugwira ntchito kwa nthawi yayitali, umathetsa vuto la kusweka lomwe ndi lovuta kuthetsa ndi "ukadaulo wothina woteteza kusweka", ndipo umapangitsa transformer yolumikizidwa kukhala yodalirika mwaukadaulo.
5. Chitetezo cha transformer yotsekedwa ndi chapamwamba kwambiri, chomwe ndi chosalowa fumbi komanso chosalowa madzi. Utomoni wa epoxy uli ndi mphamvu yabwino yolumikizirana komanso mphamvu ya dielectric yokhala ndi zitsulo ndi zinthu zosakhala zachitsulo.
Utomoni wa epoxy wokonzedwa bwino uli ndi kufupika pang'ono, kukhazikika bwino kwa mawonekedwe, kuuma kwambiri komanso kusinthasintha kwabwino. Transformer ikadzazidwa ndi guluu, chinthucho chimakhala ndi ntchito zotsutsana ndi kugwedezeka, kutenthetsa, kukhazikika komanso kuchepetsa phokoso; Transformer ikayesedwa ndikutsekedwa, kukhazikika kwa transformer kumakhala bwino, ndipo kusintha kwina sikophweka kuchitika, ndipo mikhalidwe yogwirira ntchito sikophweka kusintha.
