Thaum Transformer ua haujlwm, tus hloov pauv feem ntau yuav tsum nce lossis txo tus nqi hluav taws xob tsis yog tus kais hloov pauv hloov cov hluav taws xob.
Tus kais hloov hluav taws xob yog hluav taws xob hloov ntsia rau ntawm transformer winding los hloov cov zis ntawm ± 2 {%, thiab lwm yam} los ntawm hloov pauv sib txawv cov kais dej sib txawv.
Nyob rau hauv cov roj-raus hloov hluav taws xob, tus kais hloov hluav taws xob feem ntau yog muab raus rau hauv cov roj hloov roj hloov kho thiab ua haujlwm txias.
Peb muab ob hom Tap Changers:
{{01. tawm-load Tap TransPer
-Peby yuav tsum muab tua thaum kho cov hluav taws xob (ua haujlwm tom qab transformer yog powered tawm)
-Somilple qauv, tus nqi qis, siab ntseeg tau
-Com cov ntaub ntawv: Strip hloov pauv, tawb hloov pauv
Daim Ntawv Thov: Kev xa khoom hloov pauv, cov roj me me muaj peev xwm hloov roj (xws li S11, S13)
2. On-load Tap Changer
-Txoj kev siv hluav taws xob thaum thauj khoom tsis muaj kev ua haujlwm tsis muaj fais fab
-Om nrho cov qauv qauv, yuav tsum muaj kev txhawb nqa tsav tshuab thiab tswj cov kab ke
-Usually siv rau cov hloov pauv loj thiab cov hloov hluav taws xob loj
-Qhov khoom siv: Cov khoom siv hluav taws xob tseem ceeb xws li cov nroj tsuag hluav taws xob thiab cov khoom siv
Nyob rau hauv cov roj-rers hloov pauv, cov chaw tapping muaj xws li:±2×2.5%, ±3×2.5%, ±5%, ±4×2.5%
Qhov chaw nyob thiab cov qauv nta ntawm tus kais hloov pauv
Nyob rau hauv cov roj-raus hloov pauv, tus kais hloov pauv tuaj yeem ntsia tau rau hauv:
Sab saum toj npog (txuas nrog lub High-voltage ua), nyob rau sab phab ntsa ntawm lub transformer (nrog kev ua haujlwm sab nraud), nrog kev ua haujlwm ncaj qha rau sab nraud (tus qauv me me-mounted transformer)
Cov ntawv pom tau cov qauv ntawv suav nrog:
Sawb hom sib hloov qauv, cov qauv tawb, zawv zawg cov qauv hu
Vim li cas cov kais hloov pauv tseem ceeb?
| Rooj mov | Kev piav txog |
|---|---|
| Kev cai voltage | Ua kom muaj kev ruaj ntseg ntawm cov zis voltage thiab tiv thaiv cov khoom siv los vim yog vim yog kev sib txawv |
| Txhim kho cov khoom siv hluav taws xob zoo | Zam kev tawm ntawm cov khoom siv ntawm cov neeg siv khoom tshwm sim los ntawm voltage hloov pauv |
| Txuas ntxiv hloov kev hloov pauv lub neej | Ua rau kev faib tawm ntawm winding hloov kom tsim nyog dua, thiab txo qis poob thiab cua kub tiam |
| Ua tau raws li cov phiaj xwm sib txawv ntawm cov teb chaws sib txawv / thaj chaw | Cov kab tapping tuaj yeem kho tau raws li cov cai ntawm cov phiaj xwm phiaj xwm |
Koj yuav tsum tau them dab tsi thaum xaiv tus kais hloov pauv?
