Classification Thiab Requirements ntawm Fais Fab Transformer Roj Hom
Lub rwb thaiv tsev ntawm lub hwj chim transformer roj hom tuaj yeem muab faib ua cov rwb thaiv tsev sab hauv thiab sab nrauv. Internal rwb thaiv tsev yuav muab faib ua lub ntsiab rwb thaiv tsev thiab longitudinal rwb thaiv tsev. Lub ntsiab rwb thaiv tsev yog qhov rwb thaiv tsev ntawm cov windings thiab hauv av thiab nruab nrab ntawm cov windings. Nyob rau hauv cov roj-immersed transformers, cov roj-daim ntawv barrier rwb thaiv tsev qauv yog feem ntau siv raws li lub ntsiab rwb thaiv tsev. Kev rwb thaiv tsev tseem ceeb tuaj yeem muab faib ua qib rwb thaiv tsev thiab rwb thaiv tsev tag nrho. Qib rwb thaiv tsev txhais tau hais tias lub ntsiab rwb thaiv tsev theem ntawm transformer winding nyob ze ntawm qhov nruab nrab point yog qis dua qhov rwb thaiv tsev theem kawg ntawm winding. Hloov pauv, yog tias qhov rwb thaiv tsev theem ntawm lub taub hau thiab tus Tsov tus tw yog tib yam, nws yog hu ua tag nrho cov rwb thaiv tsev. Longitudinal rwb thaiv tsev yog qhov rwb thaiv tsev ntawm qhov chaw ntawm tib lub winding, xws li rwb thaiv tsev ntawm qhov sib txawv, tig thiab tig.
Fais fab transformer roj hom tuaj yeem tiv taus overvoltage thiab ib txwm ua haujlwm voltage thaum ua haujlwm. Withstands luv-circuit tam sim no, overcurrent thiab ib txwm ua haujlwm tam sim no thaum ua haujlwm. Cov dej noo thiab kev laus yuav tsis cuam tshuam rau kev ua haujlwm ntawm lub tshuab hloov pauv. Lub ntsiab insulating cov ntaub ntawv nyob rau hauv lub transformer yog transformer roj, insulating cardboard, xov tooj ntawv, cable ntawv, thiab crepe ntawv. Insulating paperboard yog tsim los ntawm unbleached sulfate fibers, thiab muaj ntau qhov pores ntawm fibers, yog li nws muaj zog huab cua permeability, roj nqus, nqus dej, thiab lwm yam. Yog tias cov ntawv polyamide fiber ntau siv los tiv thaiv tshav kub, nws lub neej zoo heev. Piv txwv li, siv cov ntawv cable rau insulating ntawv raj, struts, spacers, partitions, lub kaum sab xis rings, thiab lwm yam. Raws li ib yam ntawm insulating ntawv, kraft pulp yog siv los ua raw khoom, thiab lub transformer txais DL2-08, DL 2-12 hom ntawv cable, lub thickness yog 0.08mm thiab 0.12mm feem. Cov roj-immersed transformer yog tsuas yog siv rau txheej rwb thaiv tsev ntawm txheej txheej ntawm cov hlau, interlayer rwb thaiv tsev ntawm lub kauj, txhuas txheej rwb thaiv tsev, thiab lwm yam. Nws yog ib qho tseem ceeb ntawm cov ntaub ntawv insulating ntawm cov roj-immersed transformer. Xov tooj ntawv yog ua los ntawm kraft pulp thiab yog tsuas yog siv rau coil hlau rwb thaiv tsev thiab coil kawg rwb thaiv tsev. Crepe ntawv kuj yog ib daim ntawv insulating, uas yog reprocessed los ntawm cable daim ntawv ua los ntawm kraft pulp. Nws muaj cov khoom hluav taws xob zoo hauv cov roj, xws li siab nruab nrab tawg voltage thiab me me dielectric poob tangent. Crepe ntawv yog siv los qhwv lub qhov hluav taws xob transformer.
Nws tuaj yeem pom tau tias lub teb lub zog nyob rau hauv cov roj sib txawv muaj zog ntau dua li ntawm cov duab los qhia, yog li cov roj sib txawv ua qhov tsis muaj zog ntawm cov roj-ntawv rwb thaiv tsev. Thaum lub dielectric coefficients ntawm lawv nyob ze, qhov loj ntawm lub hwj chim transformer roj hom rwb thaiv tsev qauv yuav raug txo, yog li cov ntaub ntawv tshiab uas tsis tshua muaj dielectric coefficients yog cov kev tshawb fawb thiab kev loj hlob tam sim no.
