A: Tam sim no transformers yog siv los ntsuas lub hom phiaj. Yog tias tsis siv lub tshuab hluav taws xob tam sim no, cov cuab yeej ntsuas loj loj yuav tsum tau siv thiab cov kev tiv thaiv loj dua yuav tsum tau tsim los ntsuas cov txiaj ntsig siab tam sim no. Qhov no yog ob qho kev xaiv kim heev thiab txaus ntshai heev.

Q: Puas yog CT nce qib voltage?

A: Nrog lub hwj chim tus neeg xyuas pib ua haujlwm ib zaug tig winding, ntau qhov kev hloov pauv ntawm cov xaim thib ob nyob ib puag ncig ntawm toroidal core ntawm CT ua rau nws ua haujlwm raws li cov kauj ruam-up transformer hais txog qhov voltage, thiab raws li ib kauj ruam-down transformer hais txog. rau tam sim no.

Q: Dab tsi yog cov khoom siv zoo tshaj plaws rau tam sim no transformer core?

A: Qhov ntxov tshaj plaws transformer cores siv cov khoom hlau, txawm li cas los xij, txoj hauv kev tau tsim ntau xyoo los kho cov hlau ore rau hauv cov ntaub ntawv permeable ntau dua xws li silicon steel, uas yog siv niaj hnub no rau transformer core designs vim nws permeability ntau dua.

Peb nyob nraum kev tam sim no transformer manufacturers thiab lwm tus neeg nyob hauv Suav teb. Yog hais tias koj yuav mus yuav zoo tam sim no transformer ntawm tus nqi sib tw, txais tos kom tau txais cov qauv dawb los ntawm peb lub hoobkas. Tsis tas li, kev pabcuam customized yog muaj.
