Txheej txheem cej luam
JDJJ2-35 (38.5) voltage transformer yog ib qho khoom siv sab nraud ib-theem peb-winding roj-immersed khoom, haum rau cov kab hluav taws xob nrog AC 50Hz, rated voltage 35 (38.5) KV, thiab nruab nrab taw tes tsis ncaj qha hauv av.Kev ntsuas hluav taws xob, ntsuas hluav taws xob thiab lub zog hluav taws xob rau kev tiv thaiv relay thiab cov khoom siv teeb liab.Cov khoom no ua raws li IEC60044-2 thiab GB1207 "Voltage Transformer" cov qauv
Thawj winding ntawm no hom ntawm voltage transformer yog siv rau grounding lub nruab nrab point, yog li cov rwb thaiv tsev theem ntawm ob sab ntawm winding yog txawv.Cov kab hluav taws xob sab (A sab) yog cov rwb thaiv tsev tag nrho, sab hauv av (X sab) tsis yog rwb thaiv tsev tag nrho, A sab rwb thaiv tsev 35 (38.5) KV porcelain lub tes tsho ua, X sab ua rau 0.5KV lub tes tsho plooj (porcelain), qhov thib ob winding thiab qhov seem voltage winding yog feem ntau 0.5 KV lub tes tsho plooj (porcelain) coj tawm.
Qhov no voltage transformer tuaj yeem tiv taus ib-theem grounding los ntawm overvoltage yam tsis muaj kev puas tsuaj.Xws li voltage transformers yuav tsum tau siv nyob rau hauv peb pawg
Nta
JDJJ2-35 roj-immersed voltage transformer, cov khoom muaj xws li roj tank thiab lub tes tsho plooj (porcelain) ntsia rau ntawm nws.Hauv qab ntawm lub tank qis qis yog muab nrog lub ntsaws ntsaws, lub qhov taub hauv av thiab lub qhov 4-∮4mm mounting.Cov roj conservator yog ntsia rau sab saum toj ntawm lub tes tsho high-voltage porcelain nyob rau sab sauv ntawm cov roj tank tiav, thiab cov roj hluav taws xob hloov hluav taws xob txuas nrog rau A davhlau ya nyob twg ntawm thawj winding (thawj N davhlau ya nyob twg yog ntsia ntawm theem nrab. hu rau lub thawv).Lub cev kho nyob rau hauv qis roj tank muaj ib tug hlau core thiab ib kauj.Cov tub ntxhais hlau yog ua los ntawm cov ntaub ntawv zoo li cov silicon steel cov ntawv sib dhos rau hauv peb kab, nruab nrab cov tub ntxhais hlau npog lub kauj, qhov seem hluav taws xob winding, qhov thib ob winding thiab thawj winding yog qhov txhab ntawm cov pob txha insulating ze ntawm cov hlau. core nyob rau hauv lem, thiab cov windings yog sib cais los ntawm insulating cardboard., Cov khoom lag luam yog cov qauv kaw tag nrho, uas tuaj yeem tiv thaiv kev laus ntawm rwb thaiv tsev.
