Txhua qhov kev hloov kho thiab tus qauv hloov pauv tau txais cov qauv vector pawg tsim kom tau raws li cov qauv kev faib hluav taws xob thoob ntiaj teb.
Ⅱ. Basic Txhais & Txoj Cai Ua Haujlwm
1. Clock Representation Rule of Transformer Vector Group
Kev lag luam uniformly txais cov txheej txheem moos los cim cov theem kev sib raug zoo ntawm thawj thiab theem nrab kab voltages. Thawj sab kab hluav taws xob phasor yog tsau ntawm 12 teev txoj hauj lwm (0 degree), thiab theem nrab sab kab voltage phasor ua raws li lub moos tes. Tus lej moos sib xws sawv cev rau theem sib txawv (txhua lub moos tooj sib npaug 30℃hluav taws xob lub kaum ntse ntse). Cov tsiaj ntawv loj (D/Y) sawv cev siab-voltage winding kev twb kev txuas, thiab cov tsiaj ntawv me (y/d) sawv cev qis-voltage winding kev twb kev txuas; tsab ntawv "n" qhia qhov qis-voltage sab nrog nruab nrab hlau qhov hluav taws xob rau plaub-hlau fais fab mov.
2. Dyn11 Txoj Cai Kev Sib Txuas
Dyn11 txhais tau hais tias qhov siab -voltage winding txais Delta (D) kev sib txuas, qhov qis -voltage winding txais lub hnub qub (yn) kev sib txuas nrog lub qhov hluav taws xob nruab nrab. Qhov "11" qhia tias cov kab hluav taws xob theem nrab yog 330℃lagging (lossis 30℃ua) txheeb ze rau sab xub ntiag, sib xws rau 11 teev sawv ntxov.
Lub hauv paus ntsiab lus ua haujlwm yog nyob rau hauv lub voj kaw ntawm lub delta siab -voltage winding. Zero-flux sib txuas thiab thib peb harmonic flux tsim los ntawm kev ua haujlwm tseem ceeb yuav ua rau cov symmetric circulating tam sim no hauv delta winding. Lub circulating tam sim no generates thim rov qab flux rau offset feem ntau xoom-ib theem thiab thib peb harmonic flux, zoo suppressing voltage waveform distortion thiab nruab nrab point displacement. Lub hauv paus ntsiab lus no ua rau Dyn11 nyiam kev sib txuas rau siab - lub zog thiab siab - lub zog - cov kev xav tau zoo, dav siv hauv cov khoom siv hluav taws xob faib hluav taws xob, qhov twgKev rho tawm faib transformeryog dav siv rau nws superior tiv thaiv- muaj peev xwm cuam tshuam.
3. Yyn0 Txoj Cai Sib Txuas
Yyn0 txhais tau hais tias ob qho tib si siab -voltage thiab low-voltage windings txais lub hnub qub txuas nrog qis- qhov hluav taws xob nruab nrab qhov hluav taws xob. Lub "0" qhia tias thawj thiab theem nrab kab voltages yog kiag li nyob rau hauv theem (0℃theem sib txawv), coj mus rau 12 teev teev.
Sib txawv ntawm Dyn11, Yyn0 qauv tsis muaj kaw delta ncig voj. Thib peb kev sib haum xeeb tam sim no thiab xoom- ntu ntu tam sim no tsim los ntawm qhov tsis sib npaug tsis tuaj yeem ua rau muaj kev cuam tshuam zoo. Lub xoom- cov kab sib txuas tsuas tuaj yeem dhau los ntawm cov roj hloov pauv thiab lub plhaub tsis yog lub voj voog kaw, uas ua rau pom tseeb qhov nruab nrab ntawm qhov txav, asymmetric peb- theem voltage thiab me ntsis voltage waveform distortion. Nws tsuas yog tsim nyog rau cov xwm txheej nrog me me peb -theem unbalanced load.
Ⅲ. Core Performance Sib txawv ntawm Dyn11 & Yyn0
1. Harmonic & Zero-sequence Kev Tiv Thaiv Muaj Peev Xwm
Dyn11: Lub delta siab-voltage winding muab txoj hauv kev txhim khu kev qha rau peb qhov kev sib haum xeeb thiab xoom- raws li tam sim no, uas tuaj yeem cuam tshuam kev sib haum xeeb thiab tsis txhob ua paug rau sab sauv hluav taws xob. Nws kuj muaj kev ua tau zoo ntawm xob laim overvoltage kev ua haujlwm, tiv thaiv cov khoom siv hluav taws xob zoo. Cov100 kva tis transformertau txais txiaj ntsig zoo heev los ntawm qhov zoo ntawm cov qauv no hauv kev ua haujlwm txhua hnub.
Yyn0: Tsis muaj kev sib haum xeeb ntawm lub voj voog. Thib peb harmonic flux yuav induce ntxiv electromotive quab yuam ntawm theem voltage, ua rau peb -theem voltage deviation thiab nruab nrab point drift, uas yooj yim rau lub zog noj stability ntawm cov khoom siv davhlau ya nyob twg.
2. Tsis sib npaug Load Bearing Capacity
Raws li GB/T13499-2002 tus qauv, tus lej xoom-ib ntu impedance ntawm Dyn11 transformer tsuas yog 0.9 npaug ntawm qhov zoo- ntu luv-circuit impedance, thiab cov xaim nruab nrab tuaj yeem nqa tau qhov ntsuas tam sim no. Nws tuaj yeem hloov kho mus ntev - lub sijhawm ua haujlwm hauv qab 100% peb-theem tsis sib npaug ntawm cov khoom thauj, ua rauKev rho tawm faib transformerzoo tagnrho rau complex coj mus muag thiab industrial load scenarios.
Yyn0 transformer muaj xoom siab heev-ib ntu impedance (txog 60% ntawm cov ntsuas impedance). Tus qauv qhia tias qhov nruab nrab ntawm cov xaim tam sim no yuav tsum tsis pub tshaj 25% ntawm qhov ntsuas tam sim no, thiab peb theem -theem load unbalance℃yuav tsum tsis pub tshaj 15%. Kev tsis sib xws ntau dhau yuav ua rau muaj qhov cuam tshuam loj heev thiab cuam tshuam rau kev nyab xeeb ntawm cov khoom siv hluav taws xob.
3. Kev ua haujlwm txaus ntshai & kev tiv thaiv
Dyn11: Thaum lub siab -voltage side fuse yog ib zaug-theem tawg, qhov qis-voltage ib nrab theem voltage yuav poob mus rau 1/2 ntawm qhov ntsuas voltage, yooj yim ua rau cov khoom siv hluav taws xob burnout. Tsawg-voltage undervoltage tiv thaiv yuav tsum tau teeb tsa hauv kev ua haujlwm tiag tiag.
Yyn0: Tsis muaj qhov pheej hmoo poob qis tam sim ntawd nyob rau hauv ib qho - theem ua txhaum, tab sis ntev - lub sij hawm tsis sib npaug yuav ua rau kev hloov pauv kev laus thiab txo cov kev pab cuam lub neej.
Ⅳ. Daim ntawv thov Scenario Xaiv
Dyn11 Kev Sib Txuas (Qhov Tseem Ceeb Pom Zoo): Tsim nyog rau kev lag luam thiab kev lag luam tis, qhov chaw uas nquag ib zaug -theem unbalanced load, siab zog zoo yuav tsum tau, xob laim- tej thaj chaw deb thiab tag nrho nruab nrab thiab siab - muaj peev xwm faib transformers. Muaj xwm txheej uas xav tau ruaj khov los tiv thaiv- cuam tshuam kev ua haujlwm feem ntau xa cov kev faib tawm cais tawm thiab cov tswv yim 100 kva faib transformer nrog tus qauv Dyn11 teeb tsa.
Yyn0 Kev Sib Txuas: Tsuas yog tsim nyog rau kev faib khoom hauv pej xeem, me me - transformers muaj peev xwm nrog peb qhov sib npaug -theem load, thiab cov xwm txheej uas tsis tshua muaj kev cuam tshuam thiab tsis tshua muaj kev hloov pauv.
Ⅴ. Xaus
Qhov tseem ceeb sib txawv ntawm Dyn11 thiab Yyn0 transformer kev sib txuas yog nyob rau hauv siab -voltage winding qauv thiab lub hav zoov ntawm harmonic ncig voj. Dyn11 muaj qhov zoo tshaj plaws hauv kev sib haum xeeb, kev tsis sib haum xeeb ntawm kev ua haujlwm thiab lub zog ruaj khov, ua qhov kev xaiv tseem ceeb ntawm cov tshuab hluav taws xob niaj hnub. Cov qauv txhim khu kev qha ua rau 100 kva tis transformer tus qauv kev xaiv rau me me thiab nruab nrab kev lag luam fais fab tis. Lub 100 kva tis transformer yog ib qho khoom siv siab tshaj - zoo tshaj plaws uas ua rau Dyn11 cov qauv zoo. Rau kev ua haujlwm hnyav thiab nyuaj ua haujlwm, kev sib cais faib transformer muab cov khoom siv hluav taws xob ruaj khov thiab txhim khu kev qha.
JINSHANMEN TECHNOLOGY CO., LTDnruj me ntsis xaiv cov vector pawg raws li cov khoom siv scenarios. Raws li tus nqi -kev siv hluav taws xob muaj txiaj ntsig zoo, 100 kva tis transformer ua tau raws li cov qauv thoob ntiaj teb, muab cov neeg siv khoom thoob ntiaj teb nrog siab - kev ntseeg siab ntawm lub zog xa hluav taws xob thiab kev faib khoom siv daws teeb meem, suav nrog siab -kev ua haujlwm cais tawm cov khoom siv hluav taws xob hloov pauv.
