Kukhazikika kwa kutentha kwa zinthu zotetezera kutentha ndiye chinthu chachikulu chomwe chimakhudza moyo ndi mphamvu yochulukirapo ya transformer yomizidwa mu mafuta. Pofotokoza njira yokonzekera, mawonekedwe ndi kapangidwe ka mankhwala, magwiridwe antchito amagetsi komanso mphamvu yoletsa kukalamba kwa zinthu zotetezera kutentha kwambiri zomwe zimagwiritsidwa ntchito mu transformer yomizidwa mu mafuta, nkhani zomwe zimafunika kusamalidwa pozigwiritsa ntchito zimaperekedwa.

Transformer yomizidwa ndi mafuta ili ndi makhalidwe monga kutenthetsa bwino kutentha, kutayika kochepa, mphamvu zambiri komanso mtengo wotsika. Yakhala transformer yamagetsi yomwe imagwiritsidwa ntchito kwambiri mu gridi yamagetsi, ndipo kudalirika kwake kumakhudzana mwachindunji ndi chitetezo ndi kukhazikika kwa gridi yamagetsi.

Transformer yomizidwa mu mafuta imagwiritsa ntchito kapangidwe koteteza madzi kolimba. Pakadali pano, njira yotetezera mafuta yopangidwa ndi mapepala oteteza maselo ndi mafuta oteteza mchere imagwiritsidwa ntchito nthawi zambiri. Chitetezo ndi kudalirika kwa njira yotetezera kutentha ndizomwe zimapangitsa kuti transformer igwire bwino ntchito.

Pa nthawi yomwe ikugwira ntchito, makina otetezera kutentha amakalamba pang'onopang'ono chifukwa cha kutentha, mpweya, chinyezi ndi zinthu zina zambiri. Pakati pa izi, kukalamba kwa kutentha ndiye chifukwa chachikulu. Kukhazikika kwa kutentha kwa zinthu zotetezera kutentha kwakhala chinthu chachikulu chomwe chikukhudza moyo, mphamvu yonyamula katundu komanso kuchuluka kwa transformer yomizidwa mu mafuta. Malinga ndi zomwe zili mu GB / Z1094.14-2011, zinthu zotetezera kutentha za ultra-cellulose zomwe zimateteza kutentha ndi mafuta olimba kapena amadzimadzi ndi a zipangizo zotetezera kutentha kwambiri. Zipangizo zosiyanasiyana zotetezera kutentha zimatha kuphatikizidwa kukhala makina otetezera kutentha omwe ali ndi milingo yosiyanasiyana yotsutsa kutentha. Magawo osiyanasiyana oteteza kutentha ayenera kusankhidwa malinga ndi zofunikira zosiyanasiyana za kutentha, poganizira kukana kutentha komanso momwe amatetezera kutentha.

Mwachidule, zipangizo zotetezera kutentha zomwe zimagwiritsidwa ntchito mu ma transformer zimagwira ntchito makamaka ngati zotetezera kutentha komanso zothandizira makina. Ubwino wa zinthu zotetezera kutentha umatsimikizira moyo wa transformer. Zipangizo zotetezera kutentha ndi zinthu zotetezera kutentha monga mpweya, nayitrogeni, sulfure hexafluoride, ndi zina zotero. Pakadali pano, ma transformer a gasi otetezedwa ndi sulfure hexafluoride amagwiritsidwa ntchito kwambiri. Zipangizo zotetezera kutentha zamadzimadzi, zomwe zimadziwikanso kuti mafuta otetezera kutentha, monga mafuta osinthira kutentha, mafuta osinthira kutentha, mafuta a capacitor, ndi zina zotero. Zipangizo zotetezera kutentha zolimba, monga pepala lotetezera kutentha, bolodi lotetezera kutentha, matabwa, matabwa opangidwa ndi laminated amagetsi, bolodi la phenolic, bolodi la nsalu la phenolic, bolodi la nsalu lagalasi, ndi zina zotero.
