Harmonic Mitigating Transformers: Phau Ntawv Qhia Qhov Kawg rau Kev Txhim Kho Lub Zog

Los ntawm Yawei Transformer - Koj Trusted Partner hauv Power Solutions

Niaj hnub no cov hluav taws xob toj roob hauv pes yog qhov txawv ntawm qhov nws yog ib xyoo caum dhau los. Los ntawm cov chaw khaws ntaub ntawv ntim nrog cov servers mus rau cov chaw tsim khoom ua haujlwm sib txawv - zaus tsav, cov khoom siv hluav taws xob niaj hnub no feem ntautsis yog -linear. Tsis zoo li cov kab tawm ib txwm muaj uas rub tam sim no nyob rau hauv ib qho sine nthwv dej, tsis yog -linear loads rub tam sim no nyob rau hauv luv luv, abrupt pulses. Thaum qhov no yog qhov xwm txheej ntawm cov khoom siv hluav taws xob niaj hnub no, nws tsim teeb meem loj:harmonic distortion.

Harmonics yog tam sim no lossis voltages ntawm zaus uas yog qhov sib npaug ntawm qhov tseem ceeb 50/60 Hz fais fab zaus. Cov kev sib raug zoo tam sim no tsis yog ploj mus xwb -lawv rov qab los ntawm koj qhov hluav taws xob faib hluav taws xob, ua rau muaj teeb meem xws li cov khoom siv cua sov, txo kev ua haujlwm, cuam tshuam tsis zoo, thiab siv lub neej luv luv.

Qhov no yog qhov twgHarmonic Mitigating Transformers (HMTs)tuaj ua si. Ntawm Yawei Transformer, peb tsim kho HMT cov kev daws teeb meem uas nquag hais txog kev sib haum xeeb ntawm nws qhov chaw, xa lub zog huv, kev ua haujlwm siab dua, thiab kev ntseeg siab dua rau koj cov haujlwm tseem ceeb.

Lub Harmonic Mitigating Transformer yog ib qho tshwj xeeb qhuav- hom transformer engineered nrog tshwj xeeb winding configurations raunquag tso tseg lossis hloov pauv cov kev sib raug zoo tam sim no. Tsis zoo li cov qauv hloov pauv uas yooj yim dhau kev sib haum xeeb los ntawm qhov system, HMTs siv cov ntsiab lus ntawmxoom sequence flux tshem tawmthiabtheem hloovkom txo cov kev sib haum xeeb tshwj xeeb ua ntej lawv tuaj yeem ua teeb meem.

Yuav Ua Li Cas Ua Haujlwm: Technology Tom Qab Kev daws teeb meem

Cov khawv koob ntawm harmonic mitigation nyob rau hauv lub transformer thib ob windingkev teeb tsa. Nov yog qhov tshwm sim hauv Yawei HMT:

1. Zero Sequence Flux Tshem Tawm

Harmonic tam sim no, tshwj xeeb tshaj yog covtriplen harmonics(3rd, 9th, 15th), tsim xoom- sib txuas fluxes nyob rau hauv lub transformer core. Nyob rau hauv tus qauv delta -wye transformer, cov fluxes ob peb mus rau thawj windings, ua rau circulating tam sim no uas ua rau ntau tshaj kub thiab voltage distortion.

Hauv HMT, cov kab sib txuas thib ob yog tsim los tshem tawm cov xoom- cov kab sib txuasnyob rau hauv lub thib ob nws tus kheej. Cov fluxes uas tsim los ntawm 3rd, 9th, thiab 15th harmonics tshem tawm ib leeg tawm yam tsis tau mus txog lub ntsiab windings. Qhov kev tshem tawm no ua tiav ntau lub hom phiaj tseem ceeb:

Tiv thaiv triplen harmonics los ntawm circulating nyob rau hauv thawj winding

Txo qhov poobthiab tso cai rau lub transformer khiav kom txias dua

Txo impedancemus rau xoom- ntu ntu tam sim no, txo qhov tsis sib xws ntawm qhov hluav taws xob

2. Kev hloov pauv theem rau siab dua -Order Harmonics

Thaum lub winding configuration zoo nyob triplen harmonics, qhov tseem ceeb harmonics (5th, 7th, 11th, 13th, 17th, 19th) yog kho los ntawmlub tswv yim hloov pauv theem. Los ntawm kev qhia txog cov theem tshwj xeeb ntawm kev hloov pauv ntawm windings, Yawei HMTs tuaj yeem tshem tawm cov kev sib haum xeeb no hauv ntau qhov kev sib txuas, ntxuav lub zog waveform sab saud.

Ib qho ntawm cov lus nug uas peb tau txais ntawm Yawei Transformer yog:"Dab tsi yog qhov txawv ntawm Harmonic Mitigating Transformer thiab K-rated transformer?"

Qhov sib txawv yog qhov tseem ceeb thiab tseem ceeb rau kev qhia kom raug:

Xav txog nws li no: K- ntsuas ntsuas ntsuas ntsuas zoo li hnav lub tsho hnyav hauv cov cua daj cua dub- nws tiv thaiv koj, tab sis nws tsis tso cov daus. Lub HMT zoo li muaj lub ru tsev saum koj lub taub hau -nws ua kom cov daus nyob deb.

K-rated transformers (K-13, K-20, thiab lwm yam) yog yooj yimoversized thiab beefedlos tswj cov cua kub ntxiv ntawm cov kev sib raug zoo tam sim no yam tsis muaj overheating lossis ua tsis tiav ntxov. A 75 kVA K- ntsuas transformer yuav lub cev zoo ib yam li 112.5 kVA tus qauv hloov pauv, tab sis nws tseem tso cai rau cov dej sib haum xeeb ntws los ntawm koj lub cev. Lawv tsim los rau"nyob nrog"harmonics, tsis tshem tawm lawv.

Harmonic Mitigating Transformers, los ntawm qhov sib txawv, yog engineered raunquag tso tsegharmonic tam sim no. Lawv tsis cia li ua siab ntev rau qhov teeb meem -lawv daws nws ntawm qhov chaw.

Vim li cas koj yuav tsum mob siab txog kev sib haum xeeb hauv koj lub tshuab hluav taws xob? Qhov cuam tshuam mus deb dhau qhov kev qhia tshwj xeeb:

1. Muaj cua sov thiab lub zog poob

Harmonic tam sim no tsim ntxiv I²R poob hauv transformers, conductors,thiab motors. Qhov no txhais ncaj qha rau hauvcov nqi zog siab duathiabtxo cov cuab yeej siv lub neej. Nrog HMTs, txo cov thawj winding circulating tam sim no txo ​​qis poob thiab cia lub transformer khiav txias. Hauv cov ntaub ntawv chaw ib puag ncig, txawm tias qhov kev ua tau zoo me me ntxiv nce ntau heev - ob qho tib si hauv cov nyiaj daus las thiab hauv cov khoom siv hluav taws xob tsawg.

2. Voltage Distortion thiab "Cas-Topping"

Thaum cov hluav taws xob sib haum xeeb ntws los ntawm kev hloov pauv impedance, lawv tsim cov hluav taws xob poob ntawm cov zaus sib haum xeeb. Qhov no ua rauvoltage distortionntawm cov zis transformer. Standard delta-wye transformers feem ntau ncav cuag IEEE Std. 519-2014 pom zoo siab tshaj plaws ntawm 8% voltage distortion ntawm xwbib nrab ntawm tag nrho -load RMS tam sim no. Nyob rau hauv tag nrho cov load, cov transformers tuaj yeem ua rau muaj kev cuam tshuam loj heev thiab "flat-topping" uas nyuaj rau cov khoom siv hauv qab.

HMTs tau tsim tshwj xeeb los txo qis impedance rau cov kev sib raug zoo tam sim no, tswj xyuas cov hluav taws xob hluav taws xob zoo dua txawm tias nyob rau hauv qhov hnyav uas tsis yog - cov khoom tawm.

3. Tsis Siv Neeg Tshaj Tawm

Hauv peb -theem systems, triplen harmonics (3rd, 9th, 15th) yog additive nyob rau hauv nruab nrab conductor es tsis txhob tshem tawm. Qhov no tuaj yeem ua raunruab nrab tam sim no uas tshaj cov theem tam sim no, ua rau overheated neutrals, hluav taws kub nyhiab, thiab khoom siv tsis ua hauj lwm.

Yawei's Harmonic Mitigating Transformers yog qhov zoo tagnrho rau ib puag ncig uas tsis yog -linear loads predominate:

Data Centers thiabUPSCov txheej txheem

Niaj hnub nimno cov chaw zov me nyuam yog qhov chaw xav tau tshaj plaws rau lub zog zoo. Cov servers, UPS systems, thiab cov khoom siv hloov pauv txhua yam ua rau muaj kev cuam tshuam loj heev. Hauv cov chaw no:

HMTs tiv thaiv cov cuab yeej IT rhiab heev los ntawm qhov tsis sib xws ntawm qhov hluav taws xob

Lawv txo qis nruab nrab tam sim no uas yuav txwv tsis pub overheat cables

High -cov qauv tsim kom ua tau zoo txo ​​cov kev xav tau cua txias hauv qhov chaw IT txias

Qhuav- hom kev tsim kho muaj kev nyab xeeb hluav taws thiab tsis muaj kev saib xyuas thaum ntsia ze ntawm cov cuab yeej kim

Yawei muaj kev paub dhau los muab kev sib haum xeeb txo qis transformers rau cov ntaub ntawv chaw UPS cov ntaub ntawv siv, suav nrog siab -voltage daws txog 13.2 kV thiab 1500 kVA.

Telecommunications thiab Broadcast Centers

Cov chaw hauv xov tooj, cov chaw hu xov tooj, thiab cov chaw tshaj tawm xov xwm ua haujlwm tsis tu ncua tsis yog- cov khoom xa tawm los ntawm cov chaw ua liaj ua teb, cov khoom siv xov tooj cua, thiab cov khoom siv tshaj tawm. HMTs ua kom ntseeg tau tias muaj zog, huv si xa mus rau lub hom phiaj- kev sib txuas lus tseem ceeb.

Kev tsim khoom lag luam

Kev sib txawv - zaus tsav (VFDs), DC tsav, thiab lwm yam khoom siv hluav taws xob hluav taws xob hauv cov chaw tsim khoom yog cov khoom sib haum xeeb loj. Yawei HMTs tuaj yeem ua ke hauv theem- hloov pauv kev teeb tsa los tsim 12-pulse, 18-pulse, lossis txawm tias 24-pulse systems uas txo qis kev sib haum xeeb los ntawm ntau qhov chaw tsav.

Cov tsev lag luam

Cov tsev ua haujlwm nrog cov khoos phis tawj siab ntawm tus kheej, LED teeb pom kev zoo, thiab hluav taws xob ballasts tau txais txiaj ntsig zoo los ntawm kev txo qis kev sib raug zoo, tshwj xeeb tshaj yog nyob rau hauv nruab nrab tus neeg xyuas pib qhov loj me thiab tag nrho lub zog zoo.
