Phau ntawv qhia rau Radial thiab Loop Feed Transformers

Hauv kev faib hluav taws xob hluav taws xob, cov ntsiab lus "loop feed" thiab "radial feed" piav qhia txog yuav ua li cas lub zog ntws los ntawm qhov chaw mus rau cov transformers uas nqis qis voltage rau cov neeg siv kawg. Thaum cov ntsiab lus no pib los ntawm kev tsim qauv tsim, lawv feem ntau siv los qhia qhov siab -voltage (HV) bushing configuration ntawm ncoo -mounted transformers.

Kev xaiv ntawm radial lossis voj feed transformer cuam tshuam raukev ntseeg tau, yooj, thiab nqintawm koj lub network hluav taws xob. Phau ntawv qhia no piav qhia txog cov txheej txheem no ua haujlwm li cas, lawv qhov sib txawv ntawm lub cev, thiab yuav ua li cas xaiv qhov kev teeb tsa zoo rau koj qhov project.

 

 

 

Ua ntej tshuaj xyuas cov transformers lawv tus kheej, nws yog ib qho tseem ceeb kom nkag siab txog ob hom kev faib tshuab lawv ua haujlwm.

 

Radial Feed System

Lub radial pub system yog qhov yooj yim tshaj plaws thiab feem ntau hom kev faib hluav taws xob. Hauv qhov kev teeb tsa no, lub zog ntws los ntawm ib qho chaw (zoo li lub chaw nres tsheb) sab nraud raws ib txoj hauv kev mus rau cov khoom thauj, zoo li cov lus ntawm lub log. Txhua transformer tau txais lub zog los ntawm ib qho taw tes xwb.

• Qhov zoo:Nws yog qhov yooj yim los tsim, ua haujlwm, thiab tiv thaiv. Tus nqi pib qis dua vim nws xav tau cov cuab yeej siv tsawg.
• Qhov tsis zoo:Nws muajtsis muaj redundancy. Yog tias qhov chaw ib leeg tsis ua haujlwm lossis qhov ua txhaum tshwm sim ntawm txoj kab, tag nrho cov transformers downstream thiab cov neeg siv khoom poob lub zog kom txog thaum kho.

Loop Feed System

Lub voj feed system yog tsim los rau kev ntseeg siab dua. Hauv qhov kev teeb tsa no, cov kab sib faib ua ib lub voj voog, thiab cov transformers muaj peev xwm tau txais lub zog los ntawmob los yog ntau tshaj cov lus qhia los yog qhov chaw.

• Qhov zoo:Nws muabredundancy. Yog hais tias ib qho txhaum tshwm sim ntawm ib sab ntawm lub voj lossis ib qhov chaw tsis ua haujlwm, lub zog tuaj yeem raug xa rov qab los ntawm lwm qhov kev taw qhia, ua kom lub zog muaj zog. Qhov no ua rau nws zoo tagnrho rau cov chaw tseem ceeb.
• Qhov tsis zoo:Nws yuav tsum muaj ntau txoj kev tiv thaiv kev tiv thaiv thiab kev nqis peev ntau dua vim muaj cov kab txuas ntxiv thiab cov keyboards.

 

 

 

 

 

 

Qhov sib txawv tshaj plaws ntawm ob hom kev hloov pauv no nyob hauv lawv qhov siab -voltage compartment. Qhov no lub cev layout dictates yuav ua li cas lub transformer txuas mus rau daim phiaj.

 

Radial Feed Bushing Configuration

Lub radial feed transformer yog tsim los rau ib qho -point fais fab mov. Nws lub siab -voltage compartment muajpeb thawj bushings(feem ntau yog sau npe H1, H2, H3)-ib qho rau txhua tus neeg xyuas pib. Qhov kev tsim qauv yooj yim no muaj nyob rau hauv thaj chaw subdivisions, thaj chaw lag luam me, lossis raws li qhov kawg chav nyob hauv ib txoj hlua ntawm transformers qhov twg txoj kab xaus.

 

Loop Feed Bushing Configuration

Lub voj feed transformer yog tsim los rau kev hloov pauv thiab rov ua dua. Nws ntarau siab -voltage bushings-ob tag nrho ntawm peb (feem ntau sau npe H1A, H2A, H3A rau sab "A" thiab H1B, H2B, H3B rau sab "B"). Qhov no tso cai rau ob lub ntsiab pub:

• Looping Transformers Ua ke:Cables los ntawm lub hauv paus nkag mus rau thawj chav tsev "A" bushings, ces tawm ntawm nws "B" bushings los pub lub "A" bushings ntawm lub transformer tom ntej. Qhov no daisy- chains ntau units ua ke.
• Dual Source Feed:Ib chav tsev ib leeg tuaj yeem txuas nrog ob lub zog sib txawv. Internal selector keyboards tso cai rau cov neeg ua haujlwm xaiv qhov twg pub cov khoom thauj.

Thov nco ntsoov: "voj ntawm transformers" txawv ntawm "loop system." Nws muaj peev xwm txuas tau cov transformers nyob rau hauv ib lub voj, tab sis yog tias lawv tag nrho cia siab rau ib lub zog hluav taws xob, ces qhov tsis ua hauj lwm ntawm qhov chaw yuav ua rau tag nrho cov chav nyob poob lub zog - lub ntsiab lus ntawm configuration tseem radial.

Tshaj li tus naj npawb ntawm bushings, voj feed transformers muaj cov yam ntxwv siab heev uas txhim kho daim phiaj kev cia siab thiab kev tswj xyuas.

 

 

Selector Hloov Configurations

Loop feed transformers tuaj yeem nruab nrog roj -immersed selector keyboards los tswj lub zog khiav. Cov keyboards no muab lub peev xwm rau redirect tam sim no los yog cais lub transformer yam tsis muaj de-energizing tag nrho lub voj. Common configurations muaj xws li:

• Peb Ob -Txoj haujlwm Load Break Switches:Ib qho kev hloov pauv tswj lub tshuab hloov pauv nws tus kheej, ib qho tswj hwm qhov "A" pub, thiab ib qho tswj hwm "B" pub. Qhov no muaj ntau yam kev ua tau zoo, tso cai rau tus neeg teb xov tooj cais tawm lub tshuab hloov pauv thaum ua kom lub voj voog muaj zog.

 

• Plaub -Txoj haujlwm Load Break Hloov:Qhov no ib qho kev hloov pauv (feem ntau hu ua "loop feed switch") sib txuas ua haujlwm, tso cai rau cov tswv lag luam xaiv Pub A, Pub B, lossis cais lub tsev, txawm tias muaj kev tswj me ntsis tsawg dua li peb - hloov teeb.

 

 

 

 

Kev xaiv ntawm ib lub radial thiab voj feed transformer nyob ntawm qhov project cov kev cai tshwj xeeb rau kev ntseeg siab, pob nyiaj siv, thiab kev loj hlob yav tom ntej.

Ib Daim Ntawv Qhia Txog Versatility

Nws muaj peev xwm siv aLoop feed transformer nyob rau hauv radial system. Hauv cov xwm txheej zoo li no, qhov thib ob ntawm bushings (B-sab) tsuas yog capped los yog haum nrog surge arresters. Txawm li cas los xij, nws tsis tshua muaj siv aradial feed transformer nyob rau hauv ib lub voj system, raws li nws qhov peb - bushing tsim tsis tuaj yeem ua raws li qhov pub thib ob yam tsis muaj kev hloov kho sab nraud.
