FAQ

1.Dab tsi yog Dual Voltage Transformer

Ib tug dual voltage tis transformer yog ib hom ntawm transformer uas muaj peev xwm muab ntau yam tso zis voltage theem los ntawm ib tug input voltage. Qhov no yog ua tiav los ntawm kev txuas ob lossis ntau qhov hluav taws xob kais dej ntawm lub tshuab hluav taws xob windings rau cov khoom siv hluav taws xob.

Lub hauv paus winding ntawm dual voltage transformer yog tsim los txuas nrog lub zog hluav taws xob siab, feem ntau nyob rau hauv thaj tsam ntawm 15kV txog 33kV. Qhov thib ob winding muaj ntau yam kais dej uas tuaj yeem txuas rau qhov tsis tshua muaj hluav taws xob faib hluav taws xob, feem ntau ntawm qhov voltage ntawm 400V lossis 230V.

Kev siv lub tshuab hluav taws xob dual voltage tuaj yeem muab cov txiaj ntsig tseem ceeb ntawm kev ua haujlwm ntawm lub cev thiab kev txuag nqi. Los ntawm kev siv lub tshuab hloov pauv nrog ntau cov kais dej, nws muaj peev xwm muab cov qib sib txawv rau cov neeg siv khoom sib txawv, nyob ntawm lawv cov kev xav tau tshwj xeeb. Qhov no tuaj yeem pab txo qis kev siv hluav taws xob thiab txhim kho kev ua haujlwm tag nrho.

Lwm qhov txiaj ntsig ntawm kev siv dual voltage transformer yog tias nws tuaj yeem txo tus naj npawb ntawm cov transformers xav tau nyob rau hauv lub network faib. Qhov no tuaj yeem ua rau lub kaw lus yooj yim dua thiab siv nyiaj ntau dua los ua haujlwm.

Ntxiv rau lawv cov kev siv nyob rau hauv cov pa hluav taws xob faib tes hauj lwm, dual voltage transformers kuj tau siv nyob rau hauv daim ntawv thov zog tauj dua tshiab. Piv txwv li, lawv tuaj yeem siv rau hauv cov cua ua liaj ua teb lossis cov chaw tsim hluav taws xob hnub ci los hloov cov khoom siv hluav taws xob sib txawv ntawm cov tshuab hluav taws xob mus rau qhov chaw ruaj khov uas haum rau kev faib khoom.

Zuag qhia tag nrho, lub dual voltage faib transformer muab ib tug saj zawg zog thiab npaum kev daws teeb meem rau lub hwj chim tis daim ntaub ntawv, muab ntau theem voltage los ntawm ib tug input qhov twg los, thaum tseem txo tau qhov kev xav tau ntawm transformers ntxiv nyob rau hauv lub network.
