Kev tshuaj ntsuam xyuas zaus teb (SFRA) yog siv los txheeb xyuas cov teeb meem kev siv tshuab lossis hluav taws xob hauv lub zog hloov hluav taws xob, tshwm sim los ntawm luv luv circuits lossis shocks thaum thauj. Txij li thaum qhov kev taw qhia ntawm IEC 60076-18 tus qauv, SFRA tau dhau los ua ib qho kev sim. Nws raug nquahu kom ua SFRA thaum kawg ntawm qhov kev lees paub ntawm cov chaw tsim khoom thiab dua tom qab thauj thiab thaum ua haujlwm.
Cov txheej txheem suav nrog kev txhaj tshuaj sinusoidal voltage nrog nce zaus mus rau hauv ib qho kev hloov pauv winding thiab ntsuas cov lus teb teeb liab ntawm lwm qhov kawg. Los ntawm kev sib piv cov tswv yim thiab cov teeb liab tawm nrog kev siv, nws tuaj yeem txheeb xyuas cov kev hloov pauv, txav lossis deformations hauv cov khoom sab hauv.
Dielectric teb (DR) kev soj ntsuam yog siv los ntsuas cov dej noo hauv cov cellulose rwb thaiv tsev ntawm lub zog hloov hluav taws xob, uas yog qhov tseem ceeb hauv kev txiav txim siab nws lub xeev. Cov dej noo tuaj yeem tshwm sim los ntawm kev laus ntawm daim ntawv los yog ingress los ntawm faulty seals, txo kev tawg lub zog thiab ua kom lub rwb thaiv tsev aging.
Txhawm rau ntsuas kev rwb thaiv tsev, cov zis txuas nrog lub siab-voltage winding thiab cov tswv yim rau qhov qis-voltage winding, nrog cov tsis xav tau tam sim no bypassed los ntawm lub tank. Lub hwj chim factor / dissipation factor yog ntsuas ntawm ntau zaus, tsim ib qho nkhaus uas qhia txog qhov xwm txheej ntawm cov rwb thaiv tsev. Cov frequencies tsawg heev qhia tias ya raws nyob rau hauv cov khoom rwb thaiv tsev, thaum nruab nrab frequencies qhia txog cov conductivity ntawm cov kua rwb thaiv tsev.
Wuhan Huayi Hluav Taws Xob Hluav Taws Xob Technology tau cog lus rau kev tshawb fawb thiab tsim cov cuab yeej ntsuas hluav taws xob, muab cov neeg siv nrog cov kev daws teeb meem thiab cov khoom siv ntsuas hluav taws xob zoo, tshwj xeeb tshaj yog SFRA analyzer thiab DR analyzer. Koj tuaj yeem xaiv rau koj qhov kev pabcuam transformer.
