Ib qho chaw nres tsheb me melub tshuab hluav taws xobyog ib hom transformer tshwj xeeb uas tsim los hloov cov theem voltage hauv ib qho chaw hloov hluav taws xob. Nws pab txhawb kev xa hluav taws xob los ntawm cov kab xa hluav taws xob siab mus rau cov theem voltage qis dua uas tsim nyog rau kev faib rau cov neeg siv khoom.

Cov transformers uas tau teeb tsa rau ntawm Pad (PMTs) yog cov phab ej uas tsis tau muaj leej twg paub txog kev faib hluav taws xob niaj hnub no. Raws li cov khoom tseem ceeb ntawm cov tes hauj lwm fais fab hauv nroog thiab sab nraum nroog, cov chav me me no xa hluav taws xob mus rau cov tsev, cov lag luam, thiab cov chaw pej xeem kom muaj kev nyab xeeb. Tab sis dab tsi ua rau lawv tseem ceeb?

Lub pej thuam sib xyaw yog ib qho kev sib xyaw ua ke ntawm "cov pob zeb ua los ntawm cov hlau + hlau." Feem ntau, qhov qis dua ~ 2/3 yog ua los ntawm cov pob zeb ua los ntawm cov hlau (siv cov ntu ua ntej lossis cov txheej txheem ua kom poob), thaum qhov seem saum toj kawg nkaus yog lub pej thuam hlau ib txwm txuas rau lub nacelle.

Nyob rau hauv lub caij nyoog ntawm kev hloov pauv digital, cov chaw khaws ntaub ntawv tau dhau los ua lub plawv ntawm cov tuam txhab, thiab cov transformers yog cov khoom siv tseem ceeb uas ua rau lub siab no dhia. Kev xaiv lub transformer zoo tsis yog tsuas yog cuam tshuam nrog kev siv hluav taws xob zoo thiab cov nqi ua haujlwm ntawm lub chaw khaws ntaub ntawv tab sis kuj cuam tshuam ncaj qha raukev lag luam txuas ntxiv mus thiab kev ruaj ntseg ntawm cov ntaub ntawv.

Cov no yog cov cylindrical tanks uas koj pom txuas nrog cov ntoo hluav taws xob, feem ntau nrog cov fuse cutouts thiab lwm yam khoom siv.

Kev tso tawm ib feem (PD) hauv cov roj-immersed fais fab transformers tseem yog qhov kev sib tw thoob ntiaj teb lees paub hauv kev lag luam transformer. Ntau lub chaw tsim khoom tau raug kev poob loj vim yog kev ua tsis tiav ntsig txog PD.

Tej zaum yuav muaj qhov tsis zoo ntawm PD thaum lub sijhawm kuaj hauv Hoobkas, kev tshuaj xyuas los ntawm cov neeg sab nraud, lossis ntawm cov chaw ntawm cov neeg siv khoom. Kev nrhiav cov khoom siv PD feem ntau zoo li "nrhiav koob hauv cov nyom qhuav," ua rau rov ua haujlwm ntev li ntau hnub lossis ntau lub hlis, ua rau cov chaw tsim khoom lossis cov neeg siv khoom poob qis heev.

Koj puas paub qhov txawv ntawm cov amorphous alloy transformers thiab cov silicon steel transformers? Ua ib lub chaw tsim khoom transformer nrog 15+ xyoo ntawm kev paub dhau los, JZP piav qhia txog qhov txawv ntawm ob hom transformers no. Nws tsis yog qhov txawv ntawm cov ntaub ntawv xwb; nws yog kev sib ntaus sib tua ntawm kev siv hluav taws xob zoo, tus nqi, thiab cov qauv yav tom ntej.

Cov transformers peb-theem roj-immersed siv electromagnetic induction los nce lossis nqis AC voltages, ua haujlwm ua cov khoom siv tseem ceeb hauv cov tshuab fais fab los txuas cov grids ntawm ntau qib voltage. Piv txwv li, lawv tsa cov generator tso zis voltages (piv txwv li, 6kV lossis 10kV) rau cov voltages kis tau (piv txwv li, 220kV lossis siab dua) rau kev xa hluav taws xob ntev lossis txo cov hluav taws xob high-voltage rau cov voltages faib tawm (piv txwv li, 10kV / 0.4kV) rau cov neeg siv kawg.

Hauv kev ua haujlwm hluav taws xob, lub kaw lus faib hluav taws xob ua lub luag haujlwm tseem ceeb ntawm kev xa hluav taws xob thiab kev siv hluav taws xob. Kev nkag siab tob txog kev paub txog kev faib hluav taws xob, tshwj xeeb tshaj yog hais txog switchgear, yog qhov tseem ceeb rau cov kws ua haujlwm hluav taws xob thiab cov kws kho tshuab. Switchgear yog ib lub cuab yeej faib hluav taws xob sib xyaw ua ke raws li cov qauv hluav taws xob tshwj xeeb, sib xyaw cov khoom siv tseem ceeb (piv txwv li, busbars, circuit breakers) thiab cov khoom siv thib ob (piv txwv li, relays, meters). Nws lub luag haujlwm tseem ceeb yog tswj thiab tiv thaiv cov kab faib hluav taws xob thiab cov khoom siv, kom ntseeg tau tias kev ua haujlwm zoo thiab ruaj khov ntawm cov kab ke hluav taws xob.
