Taw qhia
Transformers raug xa mus rau lub plawv ntawm lub hwj chim system, thiab cov ntaub ntawv insulating ua raws li lub cev tiv thaiv kab mob ntawm lub plawv no. Nyob rau hauv lub transformer, kaum tawm txhiab ntawm cov khoom ua hauj lwm ua ke nyob rau hauv tej yam kev mob loj heev -dhau kub, high voltages, thiab muaj zog electromagnetic zog.
Hauv tsab xov xwm no, peb yuav qhia txog xya feem ntau siv cov ntaub ntawv insulating hauv transformers. Cov txheej txheem no piav qhia txog dab tsi ua rau lub tshuab hluav taws xob rwb thaiv tsev- thiab yog vim li cas nws tseem ceeb heev.
1. Insulating Pressboard
Hluav taws xob insulating pressboard yog tsim los ntawm 100% ntshiab sulfate ntoo pulp. Los ntawm lub tshuab nqus tsev ziab, nws tuaj yeem ua kom qhuav, degassed, roj -impregnated, thiab tom qab ntawd muab cov khoom siv hluav taws xob zoo thiab cov khoom siv kho tshuab.

Muab cov hardness zoo dua thiab muaj zog hluav taws xob ntau dua, thiab feem ntau yog siv rau cov khoom siv insulating xws li insulating cylinders, spacers, thiab blocks, nrog rau cov khoom laminated.
High -ntaub ntawv board
Cov khoom siv hluav taws xob thiab kev ua haujlwm zoo heev thiab feem ntau yog siv rau hauv cov khoom tsis yog- dabtsi yog khoov xws li cov phaj siab, cov phaj nraub qaum, thiab roj- qhov sib txawv spacers.
2. Laminated Ntoo
Hluav taws xob laminated ntoo yog tsim los ntawm siab - ntoo zoo xws li maple, birch, thiab tshauv, uas tsis muaj paug transformer roj. Cov txheej txheem suav nrog steaming, teb txiav, ziab, txheej nrog insulating resin, thiab tom qab ntawd kho hauv qhov kub thiab txias. It has the advantages of moderate density, high mechanical strength, ease of vacuum drying, and easy mechanical processing. Nws qhov dielectric tas li yog ze rau ntawm cov roj transformer, thiab nws tuaj yeem siv tau ntev hauv cov roj transformer ntawm 105 degree.

Los ntawm 20mm, nce nyob rau hauv 5mm increments. |
| Imported | 1000mm × 2000mm (Qhov loj tshaj plaws mus txog 4200mm × 3400mm) |
6mm-200 hli |
Laminated ntoo feem ntau yog siv rau kev tsim cov phaj siab, cov phaj txhawb nqa, cov phaj bracing, cov hlau lead, clamping blocks, thiab pwm rau tsim cov khoom insulating. Tam sim no, domestic laminated ntoo kuj tuaj nyob rau hauv lub nplhaib thiab bar daim ntawv. Cov rings yog tsim los siv cov txheej txheem tshiab uas ua kom muaj zog ntsug bending zog ntawm txhua lub ntsiab lus ntawm qhov khoob, ua rau lub zog tag nrho cov neeg kho tshuab muaj zog thiab cov qauv siab ntawm elasticity. Lawv feem ntau yog siv los ua cov phaj siab thiab txhawb nqa. Cov tuav loj feem ntau muaj qhov tshwj xeeb ntawm 50mm × (50, 60, lossis 70mm) × 3000mm thiab feem ntau yog siv los ua cov hlau clamps.
3. Daim ntawv nplaum
Muab ob npaug - daim ntawv nplaum muaj nyob rau hauv ob qib cov ntsiab lus nplaum. Ib hom muaj cov ntsiab lus nplaum ntau dua thiab feem ntau yog siv rau kev nias laminated pressboard. Thaum siv, ib daim ntawv ntawm ob -ib daim ntawv nplaum yog muab tso rau ntawm ob daim ntawv xovxwm, hloov cov txhuam hniav ntawm phenolic resin nplaum. Txoj kev no ua rau kev ua haujlwm yooj yim, thiab tshem tawm lub sijhawm ziab kom qhuav rau cov nplaum nplaum. Lwm hom muaj cov ntsiab lus nplaum qis dua thiab feem ntau yog siv los ua cov ntawv thaiv kev tiv thaiv, qhov chaw uas nws tau pw ntawm insulating pressboard thiab semi-conductive paper.

5. Kab ntawv
Cable ntawv yog tsim los ntawm ntshiab sulfate ntoo pulp. Nws muaj lub zog zoo txhua yam thiab dielectric zog. Hom ntawv no feem ntau yog siv rau tig- rau- tig rwb thaiv tsev thiab txheej rwb thaiv tsev ntawm transformer winding conductors, nrog rau cov insulating leads, kais sib txuas, electrostatic rings, thiab rau dov insulating raj.
6. Crepe Ntawv
Insulating crepe ntawv yog tsim los ntawm creping hluav taws xob- qib insulating ntawv. Nws muaj wrinkles hla nws qhov dav, uas tuaj yeem ncab thaum siv. Cov txheej txheem creping sib txawv ua rau cov ntaub ntawv sib txawv ntawm elongation. Daim ntawv crepe feem ntau yog siv los qhwv rwb thaiv tsev hauv cov khoom siv hluav taws xob, xws li insulating qhov kawg ntawm windings, leads, thiab electrostatic rings.
7. Epoxy iav ntaub Laminate
Epoxy- iav ntaub laminate yog tsim los ntawm impregnating iav fiber ntau daim ntaub nrog epoxy resin thiab kho nws nyob rau hauv tshav kub thiab siab. Nws nthuav tawm cov neeg kho tshuab siab zog ntawm qhov nruab nrab kub thiab ruaj khov hluav taws xob ntawm qhov kub siab. Nws feem ntau yog siv rau kev tsim khoom inter-cov roj ducts thiab hloov shims thaum lub rooj sib txoos zaum kawg.
