- 🛠️ Cov qauv yooj yim, tus nqi qis, kho yooj yim
- Tsim los rau kev sivtsis tas yuav tsum muaj kev tswj xyuas qhov voltage
Tej kev siv:
- Teem sijhawm hloov voltage (piv txwv li, hloov raws caij nyoog)
- Me me industrial transformers thiab faib transformers
2. Ntawm -Load Tap Changer (OLTC)
Cov yam ntxwv tseem ceeb:
- Pab taunyob -load voltage regulationtsis muaj zog cuam tshuam
- Siv cov kev hloov pauv impedance (resistor / reactor) los txwv cov circulating tam sim no thaum hloov
- Cov qauv nyuaj nrog kev saib xyuas ntau dua, tab sis muaj kev tswj xyuas qhov hluav taws xob hloov tau rau cov phiajcim ntse
Cov qeb:
(1) Resistor Hom OLTC:
- Kev hloov ceev (millisecond teb)
- Zoo tagnrho rau nruab nrab / me transformers (tsawg dua los yog sib npaug rau 110kV)
(2) Reactor Hom OLTC:
- Smoother tab sis qeeb kev hloov pauv
- Txaus siab rau cov transformers loj (Ntau dua lossis sib npaug rau 220kV)
Cov ntawv thov tseem ceeb:
- Fais fab system main transformers (piv txwv li, substations)
- Kev sib txuas ua ke zog tauj dua tshiab (cua / hnub ci kev sib txuas)

NLTC: Tus nqi- cov haujlwm tseem ceeb nrog kev hloov kho tsis tu ncua
OLTC: Lub tshuab hluav taws xob tseem ceeb uas xav tau tiag tiag - lub sijhawm tswj hwm
Yav tom ntej Trends:Khoom - xeev kais hloov pauv(arc-tsawg hloov) thiabIoT- qhib OLTCyuav dominate tom ntej no -gen solutions.
3. Txoj Cai Ua Haujlwm
Tsis muaj -Load Type: Mechanically hloov cov kais dej tom qab fais fab -tawm, ncaj qha hloov qhov sib piv.
Ntawm -Load Type:
Ua ntej - xaiv ntawm Tap: Tus xaiv ua ntej - txuas lub hom phiaj kais ua ntej.
Kev hloov pauv tam sim no txwv: Txuas cov qub thiab tshiab kais dej los ntawm lub resistor / reactor los tiv thaiv luv luv circuits.
Arc Extinction thiab Switching: Siv lub tshuab nqus tsev cuam tshuam lossis roj -immersed arc-quenching thev naus laus zis los txiav tawm tam sim no thiab ua tiav cov txheej txheem hloov.
4. Kev teeb tsa & kev sib txuas
Qhov chaw: High-voltage side (kev lag luam vim qis tam sim no), txuas nrog winding kais ntawm cov khoom siv insulated.
Piv txwvHV windings nrog ± 2.5% kais dej; coj mus rhaub changers dynamically xaiv lem (piv txwv li, 110kV → 105kV).
5. Core Functions
Voltage Stabilization: Compensates rau daim phiaj voltage fluctuations los yog load hloov.
Efficiency Optimization: Txo reactive zog poob; txhim kho kev sib kis tau zoo.
Tsis ua kev kaw tus kheej: Qee qhov kev tsim qauv tuaj yeem cais cov seem uas tsis raug.
Renewable Energy Integration: Smoothes intermittent power fluctuations los ntawm cua / hnub ci tiam.
6. Cov thev naus laus zis tseem ceeb & kev sib tw
Arc Quenching: Lub raj mis lub tshuab nqus tsev lossis roj- txoj hauv kev raus dej yuav tsum tiv taus siab - zaus tam sim no surges.
Hloov ceev: Millisecond- theem ua haujlwm kom tsis txhob cuam tshuam lub zog.
Rwb thaiv tsev tsim: Xaiv cov khoom siv hluav taws xob hluav taws xob siab (piv txwv li, epoxy resin) ntawm cov kais dej.
Ntse nta: Kev koom ua ke ntawm cov sensors thiab AI algorithms rau kev saib xyuas kev kwv yees.
Kev Sib Tw Loj:
Hu rau Erosion: Frequent switching causes contact wear (>40% ntawm kev ua tsis tiav).
Mechanical Hnav: Kev laus tsav mechanisms ua rau jamming.
Roj paug: Carbon particle buildup nyob rau hauv cov roj-immersed hom degrades rwb thaiv tsev.
7. Kev tu & kev ua tsis tiav
Kev tu txhua hnub:
Roj -Yam: Kev ntsuas roj tsis tu ncua (dielectric zog, noo noo cov ntsiab lus); lim / hloov.
Qhuav -Hom: Tshem tawm plua plav; tiv tauj oxidation tshuaj xyuas.
Mechanical Cheebtsam: Lubrication ntawm tsav mechanisms; coj mus rhaub txoj hauj lwm calibration.
