Taw qhia
Tus kais hloov pauv yog lub cuab yeej tseem ceeb rau kev kho cov zis voltage ntawm lub transformer. Nws lub luag haujlwm tseem ceeb yog hloov pauv qhov hloov pauv hloov pauv los ntawm kev hloov mus rau qhov sib txawv ntawm cov kais dej, yog li ua tiav kev tswj hwm hluav taws xob. Cov cuab yeej no tau siv dav hauv cov tshuab hluav taws xob kom tswj tau daim phiaj hluav taws xob ruaj khov thiab ua tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob nyob rau hauv ntau yam kev thauj khoom.
Raws li txoj kev khiav hauj lwm, kais hloov pauv feem ntau tau faib ua ob hom: On-Load Tap Changers (OLTC) thiab Off-Load Tap Changers. Tus qub tuaj yeem ua qhov hloov pauv voltage thaum lub transformer muaj zog. Lawv tsim nyog rau cov xwm txheej uas xav tau kev siv hluav taws xob tas mus li. Cov tom kawg yuav tsum tau hloov thaum lub transformer tag nrho de-energized. Lawv feem ntau siv nyob rau hauv cov xwm txheej uas nquag hloov voltage tsis tas yuav tsum tau.
Coj mus rhaub qhov chaw chaw&Kauj ruam Loj
Feem ntau cov kais hloov pauv yog tsim los rau ntau - txoj cai txoj haujlwm, feem ntau muab kev hloov pauv xws li ± 5% lossis ± 10%. Qhov kev hloov kho qhov hluav taws xob qhov loj me rau ib txoj hauj lwm feem ntau yog ± 0.5% thiab ± 1.5%.
Qhov tseeb ntawm kev tswj hluav taws xob yog cuam tshuam los ntawm cov hauv qab no:
Coj mus rhaub Setting
Ib qho kais me me ua rau muaj kev tswj xyuas ntau dua.
Kev ntsuas yuam kev
Qhov tseeb ntawm qhov ntsuas qhov ntsuas hluav taws xob muaj feem cuam tshuam rau kev tswj cov txiaj ntsig.
Mechanical Hnav
Kev siv sijhawm ntev - tuaj yeem ua rau muaj kev hloov pauv hauv kev tiv thaiv kev tiv thaiv.
Ambient Kub
Kub variations cuam tshuam winding tsis kam, li no influencing lub voltage tso zis
Mechanical kais hloov pauv tswj qhov hluav taws xob los ntawm lub cev hloov ntawm qhov sib txawv winding lem. Cov khoom tseem ceeb muaj xws li kev sib txuas sib txuas, lub tshuab tsav, lub tshuab xaiv, thiab kev hloov pauv hloov.
Hloov cov neeg sib txuas yog lub luag haujlwm rau kev hloov lub cev ntawm cov kais dej sib txawv kom ntseeg tau tias muaj kev txuas ntxiv tam sim no.
Ib qho kev tsav tsheb feem ntau yog tsim los ntawm lub zog, kev sib txuas, thiab lwm yam. Nws ua rau cov neeg xaiv thiab hloov cov neeg sib cuag.
Ib tug selector yog siv los xaiv txoj haujlwm kais uas xav tau tam sim no.
Transition resistors yog thaum lub sij hawm hloov cov txheej txheem los txwv tam sim no hloov tam sim no thiab tiv thaiv arcing.
Cov txheej txheem rwb thaiv tsev txhawb nqa tag nrho cov qauv hloov kom ntseeg tau tias muaj hluav taws xob sib cais ntawm cov khoom.
Cov tshuab hluav taws xob hloov pauv hloov cov kev sib txuas ib txwm siv nrog cov khoom siv hluav taws xob hluav taws xob, xws li IGBTs, MOSFETs, thiab SCRs, kom ua tiav tsis yog - tiv tauj hloov. Qhov kev tsim no zam cov teeb meem xws li kev hnav thiab arcing, yog li txhim kho cov cuab yeej ruaj khov thiab kev ntseeg tau.

Txoj Kev Loj Hlob
Intelligent & Digital Design
Tshiab- tiam kais hloov pauv ua ke nrog cov sensors thiab kev sib txuas lus, txhawb kev saib xyuas thiab tswj cov chaw taws teeb:
Integrated kub sensors rau tiag -lub sij hawm saib xyuas ntawm kev hloov kub nce.
Txhawb kev sib txuas lus raws tu qauv xws li Modbus RTU rau kev cuam tshuam nrog SCADA systems.
Ua -hauv kev kuaj xyuas qhov tsis raug algorithms kom paub meej txog kev hloov pauv txawv txav.
Cov Khoom Siv Tshiab & Kev Txhim Kho Kom Zoo
Cov ntaub ntawv tshiab tau raug qhia rau hauv kais changer manufacturing los txhim kho lawv cov kev ua tau zoo:
Nano insulating cov ntaub ntawv tuaj yeem ua rau lub zog dielectric thiab txo lub cev loj.
High -conductivity tooj liab alloys tuaj yeem txo kev tiv thaiv kev tiv thaiv thiab txo qis kev tsim hluav taws xob.
Modular tsim ua kom yooj yim hloov thiab kho sai.
Nyob rau hauv lub neej yav tom ntej, kais hloov pauv yuav maj mam hloov mus rau Adaptive Voltage Regulation, Status Perception, thiab Remote Control. Lawv tau dhau los ua cov khoom ntse ntse tseem ceeb hauv cov chaw ua haujlwm ntse.
