Qhov Voltage Transformer

Los ntawm lub hom phiaj

Ntsuas voltage Transformer los yog ntsuas winding ntawm voltage Transformer: nyob rau hauv ib txwm voltage ntau yam, muab daim phiaj voltage ntaub ntawv rau lub ntsuas thiab metering ntaus ntawv;

Kev tiv thaiv voltage Transformer los yog kev tiv thaiv winding ntawm lub voltage Transformer: Nyob rau hauv lub xeev ntawm lub hwj chim daim phiaj txhaum, muab lub hwj chim daim phiaj voltage cov ntaub ntawv rau cov khoom xws li relay tiv thaiv.

Muab faib los ntawm kev rwb thaiv tsev nruab nrab

Qhuav hom voltage Transformer: Nws yog impregnated nrog insulating kua roj vanish raws li rwb thaiv tsev los ntawm cov ntaub ntawv insulating, thiab nws yog feem ntau siv nyob rau hauv qis voltage theem thiab hauv qab no;

Pouring Rwb thaiv tsev Voltage Transformer: Cam khwb cia los ntawm epoxy resin lossis lwm yam khoom siv sib xyaw. Nws feem ntau yog siv nyob rau theem voltage hauv qab no.

Roj-immersed voltage Transformer: Insulating ntawv thiab insulating roj yog siv los ua rwb thaiv tsev. Nws yog hom qauv siv ntau tshaj plaws hauv Suav teb thiab feem ntau siv rau cov qib voltage hauv qab no.

Gas-insulated voltage Transformer: Gas yog siv los ua cov rwb thaiv tsev tseem ceeb, uas feem ntau yog siv nyob rau hauv cov qib siab dua.

Cov Transformers uas tsis tshua muaj hluav taws xob feem ntau siv rau kev ntsuas yog qhuav, thiab cov high-voltage los yog ultra-high-voltage sealed gas-insulated (xws li sulfur hexafluoride) Transformers kuj qhuav. Pouring hom yog tsim rau voltage Transformers ntawm 35kV thiab hauv qab no. Cov khoom lag luam siab tshaj 35kV yog roj-immersed.

Muab faib los ntawm cov theem

Feem ntau cov khoom yog ib theem. Vim tias qhov hluav taws xob Transformer muaj lub peev xwm me me thiab lub cev me me, qhov kev xav tau ntawm cov rwb thaiv tsev sab hauv thiab sab nraud ntawm peb-theem high-voltage bushings yog qhov nyuaj rau kev ua tau zoo, yog li tsuas yog 3-15kV khoom qee zaum siv peb-theem qauv.

Raws li lub hauv paus ntsiab lus ntawm voltage conversion

Electromagnetic voltage Transformer: Qhov voltage yog hloov raws li lub hauv paus ntsiab lus ntawm electromagnetic induction. Lub hauv paus ntsiab lus yog kiag li zoo ib yam li cov qauv yooj yim thiab Transformer. Feem ntau voltage theem nyob rau hauv Tuam Tshoj thiab hauv qab no yog saws;

Capacitive voltage Transformer: Nws muaj lub capacitor voltage divider, them nyiaj reactor, intermediate Transformer, damper, thiab cov khoom siv tiv thaiv qhov sib txawv. Nws yog siv nyob rau hauv nruab nrab grounding systems rau kev ntsuas voltage, ntsuas fais fab, kev tiv thaiv relay, thiab cov cab kuj sib txuas lus. siv;

Photoelectric voltage Transformer: Kev hloov pauv hluav taws xob tau pom los ntawm lub hauv paus ntsiab lus ntawm kev hloov pauv photoelectric, uas tseem tab tom txhim kho.

Raws li cov kev cai ntawm kev siv

Hom hluav taws xob sab hauv tsev Transformer: ntsia hauv cov khoom siv hluav taws xob sab hauv tsev, feem ntau siv ntawm thiab qis dua qhov voltage;

Sab nraum zoov-hom voltage Transformer: Nruab rau sab nraum zoov hluav taws xob faib khoom, feem ntau yog siv nyob rau theem voltage thiab siab dua.

Raws li winding rau hauv av ua haujlwm raws li txoj cai

Voltage Transformer nrog thawj winding grounded: Qhov kawg ntawm thawj winding ntawm ib theem voltage Transformer los yog nruab nrab point ntawm thawj winding ntawm peb-theem voltage Transformer yog ncaj qha grounded;

Voltage Transformers uas tsis muaj thawj winding: Ib-theem voltage Transformers yog insulated los ntawm hauv av ntawm ob lub terminals ntawm thawj winding; tag nrho cov seem ntawm thawj winding ntawm peb-theem voltage Transformer, nrog rau cov terminals, yog insulated los ntawm hauv av, thiab cov rated rwb thaiv tsev theem yog zoo ib yam.

Muab faib los ntawm magnetic circuit structure

Ib-theem voltage Transformer: thawj winding thiab theem nrab winding (ntau qhov thib ob windings tuaj yeem teeb tsa ntawm tib lub tub ntxhais hlau raws li qhov yuav tsum tau ua, thiab cov tub ntxhais hlau yog qhov muaj peev xwm hauv av.

Cascade hom voltage Transformer: thawj winding yog muab faib ua ob peb units nrog tib tus naj npawb ntawm lem thiab txuas nyob rau hauv series ntawm theem thiab hauv av. Txhua chav tsev muaj nws tus kheej cov tub ntxhais hlau ywj pheej, muaj ntau lub cores hlau, thiab cov tub ntxhais hlau muaj qhov hluav taws xob siab. Secondary winding (ntau lub voj voog thib ob tuaj yeem teeb tsa ntawm chav tsev kawg txuas nrog hauv av raws li qhov yuav tsum tau ua. Hom qauv no feem ntau siv nyob rau theem voltage hauv Suav teb;

Combined Transformer: Ib qho Transformer uas yog sib xyaw ua ke thiab tsim los ntawm cov hluav taws xob hloov hluav taws xob thiab lub tshuab hluav taws xob tam sim no hu ua Transformer ua ke, thiab tseem muaj Transformer uas tau tsim ua ke nrog cov khoom siv hluav taws xob ua ke ua ib qho Transformer ua ke.
