Mu ma transformer, kuwonjezera pa ma coil oyambira ndi achiwiri, palinso zinthu zina zofunika komanso zowonjezera. Zipangizo zotetezera kutentha ndi chimodzi mwa zinthu zofunika kwambiri pa transformer. Kuteteza kutentha kokwanira pakati pa magawo osiyanasiyana ogwira ntchito a transformer ndikofunikira kuti igwire ntchito bwino. Kuteteza kutentha kokwanira sikofunikira kokha kuti ma coil asiyane, kapena kuchokera pakati ndi thanki, komanso kumateteza transformer ku ma voltages omwe amabwera chifukwa cha ngozi.

Zipangizo zolimba zotetezera kutentha zomwe zimagwiritsidwa ntchito kwambiri mu transformer ndi

1. Pepala lamagetsi, pepala la kraft
2. Bolodi yosindikizira, pepala la diamondi

Thkuti ndiPepala lopangidwa ndi cellulose lomwe limagwiritsidwa ntchito kwambiri poteteza kondakitala mu ma transformer odzazidwa ndi mafuta. Pali mitundu yosiyanasiyana ya mapepala a cellulose monga:

Pepala lopangidwa ndi matabwa:

Kalasi ya kutentha E (120º) malinga ndi IEC 554-3-5 mu makulidwe kuyambira 50 mpaka 125 ma microns.

Pepala lokonzedwanso ndi kutentha kwambiri la kalasi ya kutentha ya E (120°) malinga ndi IEC 554-3-5, makulidwe ake ndi kuyambira ma microns 50 mpaka 125.

Pepala la Epoxy lomwe lili ndi diamondi limakhuthala mosiyanasiyana. Izi zimapangitsa kuti kutentha kukhale koyenera poyerekeza ndi pepala la Kraft.

3. Matabwa ndi matabwa otetezedwa ndi kutentha

Matabwa amagetsi opangidwa ndi laminated amagwiritsidwa ntchito kwambiri ngati zinthu zotetezera kutentha ndi zothandizira mu ma transformer ndi ma transformer a zida. Ali ndi zabwino zambiri monga mphamvu yokoka yapakati, mphamvu zambiri zamakanika, kuumitsa mosavuta vacuum, palibe zoyipa mkati mwa mafuta a transformer, kukonza kosavuta kwa makina, ndi zina zotero. Chokhazikika cha dielectric cha chinthuchi chili pafupi ndi mafuta a transformer, kotero chimagwirizana bwino ndi kutenthetsa kutentha. Ndipo chingagwiritsidwe ntchito mu mafuta a transformer a 105℃ kwa nthawi yayitali.

Anthu nthawi zambiri amagwiritsa ntchito chipangizochi popanga zinthu zopanikizika zapamwamba/zotsika, zitsulo zothandizira chingwe, ziwalo, zotchingira ma spacer mu ma transformer oviikidwa mu mafuta, ndi zomangira mu ma transformer a zida. Chinalowa m'malo mwa mbale zachitsulo, mapepala oteteza kutentha, mapepala a epoxy paper, lamination ya epoxide wrapped glass fabric m'magawo awa, ndikuchepetsa ndalama zogulira ndi kulemera kwa ma transformer.

4. Tepi yoteteza kutentha

Tepi yamagetsi (kapena tepi yoteteza kutentha) ndi mtundu wa tepi yomwe imakhudzidwa ndi kupanikizika yomwe imagwiritsidwa ntchito kutetezera mawaya amagetsi ndi zinthu zina zomwe zimapangitsa magetsi kukhala olimba. Itha kupangidwa ndi mapulasitiki ambiri, koma PVC (polyvinyl chloride, "vinyl") ndiyo yotchuka kwambiri, chifukwa imatambasuka bwino ndipo imapereka chitetezo chogwira ntchito komanso chokhalitsa. Tepi yamagetsi yotetezera kutentha ya kalasi H imapangidwa ndi nsalu ya fiberglass.

Ife, TRIHOPE, tapereka mapepala ambiri a kraft, pepala la presspan, pepala la diamondi, matabwa okhuthala ndi tepi yotetezera kutentha kwa makasitomala akunja, kuphatikizapo Mexico, South Africa, Pakistan ndi zina zotero. Tikukulandirani kuti mutumize mafunso ku kampani yathu.

Mafuta ndi gawo lofunikira kwambiri la kutchinjiriza kwa transformer yonse. Ntchito yayikulu ya kutchinjiriza mafuta mu transformer ndikupereka kutchinjiriza kwamagetsi pakati pa zigawo zosiyanasiyana zopatsidwa mphamvu; imagwiranso ntchito ngati chophimba choteteza kuti chitsulo chisawonongeke. Ntchito ina yofunika ya mafuta ndikuwonjezera kutentha. Ma cores ndi ma windings a transformer amatenthedwa akamagwira ntchito chifukwa cha kutayika kwa mphamvu zosiyanasiyana. Mafuta amatenga kutentha kuchokera pakati ndi ma windings mwa njira yoyendetsera ndikunyamula kutentha kupita ku thanki yozungulira, yomwe imatulutsidwa kupita kumlengalenga.
