2500 KVA Av Mount Transformer-12.47/0.6 ​​KV|USA 2025

01 General

1.1 Project Description

2500 kVA hauv av mount transformer tau xa mus rau Tebchaws Meskas hauv xyoo 2025. Lub zog ntsuas ntawm lub transformer yog 2500 kVA nrog KNAN txias. Qhov siab voltage yog 12.47GRDY / 7.2 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov tsawg voltage yog 0.6Y / 0.346 kV, lawv tsim ib pawg vector ntawm YNyn0.

Lub transformer txais yuav peb-theem peb-limb core qauv, uas ua kom ruaj khov sib nqus Circuit Court kev ua tau zoo, txo cov hlau tsis zoo, thiab txhim kho kev ua haujlwm ruaj khov. Nws tau ntim nrog FR3 roj raws li cov rwb thaiv tsev thiab cua txias nruab nrab, siab - zoo ib puag ncig zoo rwb thaiv tsev roj uas boasts zoo thermal stability, hluav taws kub tsis kam thiab biodegradability, muab kev tiv thaiv zoo rau cov khoom siv hluav taws xob sab hauv thaum ua raws li kev tiv thaiv ib puag ncig.

Hais txog kev siv hluav taws xob zoo, cov khoom lag luam nruj me ntsis ua raws li DOE cov qauv kev ua haujlwm zoo, ua kom zoo tshaj qhov tsim ntawm cov tub ntxhais thiab winding kom txo qis tsis muaj -load poob thiab load poob, paub txog kev txuag hluav taws xob thiab kev txo qis thaum lub sijhawm ua haujlwm ntev -, thiab ua rau muaj txiaj ntsig zoo rau cov neeg siv. Txhawm rau kom muaj kev nyab xeeb ntawm kev ua haujlwm, lub tshuab hloov pauv tau nruab nrog kev sib cais ntawm lub tes tsho hauv av, uas tshwj xeeb yog siv rau cov ntaub thaiv npog hauv av. Qhov kev teeb tsa no tuaj yeem tiv thaiv kev cuam tshuam ntawm electromagnetic cuam tshuam, txo qis ib feem, thiab tiv thaiv lub tshuab hluav taws xob los ntawm cov hluav taws xob hluav taws xob, ua kom muaj kev nyab xeeb ntawm cov khoom siv thiab daim phiaj hluav taws xob.

Sab nraud, lub transformer nta cov hmoov coated dawb tiav (RAL 9003), uas tsis tsuas yog muaj kev tiv thaiv corrosion zoo heev thiab huab cua tsis kam hloov mus rau ntau qhov chaw sab nraum zoov hnyav, tab sis kuj nthuav tawm lub ntsej muag huv si thiab zoo nkauj, sib xyaw zoo nrog cov xwm txheej sib txawv. Zuag qhia tag nrho, lub ncoo mounted transformer no ua ke nrog kev tiv thaiv ib puag ncig, kev ua haujlwm siab, kev nyab xeeb thiab ua haujlwm ntev, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev faib hluav taws xob hauv nroog thiab hauv nroog.

02 Kev tsim khoom

2.1 H 0

H0 bushing rau hauv av mount transformer yog tag nrho - shielded, submersible - ntsuas interface rau kev sib txuas hauv av siab -voltage cables (feem ntau 15/25 kV). Nws compact, ib qho -daim elastomeric tsim muab kev nyab xeeb kiag li, tsis yog - raug kev sib txuas los ntawm kev sib xyaw ua ke nrog cov ntaub thaiv npog sab nraud. Cov yam ntxwv tseem ceeb feem ntau suav nrog qhov ntsuas qhov ntsuas thiab cov kev cai rau ntsaws- hauv cov khoom siv xws li qhov ntsuas qhov ua txhaum lossis cov neeg ntes, ua rau nws muaj zog, txij nkawm- cov khoom pub dawb rau cov khoom siv hauv av.

2.2 Ob Txoj Haujlwm Loadbreak Hloov

Ob - txoj hauj lwm load break hloov ntawm lub hauv paus mount transformer yog ib qho tseem ceeb ntawm kev tswj cov khoom siv hauv av, uas tsuas muaj ob lub xeev ua haujlwm: "Kaum" kom muaj zog rau hauv Circuit Court thiab "Qhib" rau de- energize nws, tsis muaj cov haujlwm nruab nrab. Tsim kom muaj kev nyab xeeb thiab ua rau cov khoom tawg tam sim no nyob rau hauv kev ua haujlwm ib txwm muaj, ntau qhov kev hloov pauv no feem ntau siv rau hauv tandem los pab kom tswj tau yooj yim ntawm cov kab sib txawv (piv txwv li, A thiab B feeder kab), txhawb kev txhim khu kev xa hluav taws xob los ntawm transformer mus rau kab sib chaws.

2.3 LV Bushing Support

LV bushing kev txhawb nqa rau ncoo-mounted transformers yog ib qho tseem ceeb tiv thaiv accessory uas siv upward nro rau qis -voltage bushings, counteracting downward nyhav ntawm ntau yam txuas cables-tshwj xeeb tshaj yog thaum 8 los yog ntau tshaj cables raug ntsia los yog spade extensions yog siv. Los ntawm kev tshem tawm cov kab mob ntawm cov bushing los ua ke thiab nws cov sealing gasket, nws tiv thaiv lub gasket los ntawm crushed tiv thaiv lub transformer tank phab ntsa, yog li tsis txhob transformer roj to thiab tuav lub hermetic foob rau ntev - lub sij hawm ua hauj lwm kev cia siab rau.

2.4 Cov ntaub thaiv npog

Cov ntaub thaiv npog hauv av hauv av mount transformer yog cov txheej txheem tseem ceeb, feem ntau txuas nrog lub ntiaj teb muaj peev xwm, uas nyob ib puag ncig cov khoom nyob sab hauv. Nws lub luag haujlwm tseem ceeb yog ua kom muaj kev nyab xeeb los ntawm kev muaj thiab ua kom muaj kev nyab xeeb cuam tshuam cov kev txhaum tam sim no rau hauv av, tiv thaiv lub tshuab hluav taws xob los ntawm kev ua kom muaj zog thiab tiv thaiv cov neeg ua haujlwm. Nyob rau tib lub sijhawm, nws muab qhov tseem ceeb ntawm electromagnetic shielding, uas txo qis kev cuam tshuam los ntawm ib puag ncig sab nraud thiab txo kev ntxhov siab ntawm lub tshuab hluav taws xob rwb thaiv tsev, yog li ua kom muaj kev ntseeg siab thiab ua haujlwm ntev. Qhov tseem ceeb ntawm no txhawb cov phiaj xwm niaj hnub xav tau rau kev ua haujlwm zoo thiab kev sib raug zoo nrog kev saib xyuas cov kab ke hauv kev hloov pauv hluav taws xob sib txuas.

2.5 HV Bushing

Lub HV (siab-voltage) bushing ntawm ib lub ncoo{1}}mounted transformer yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob sib txuas, feem ntau muaj nyob rau hauv qhov ntsuas hluav taws xob ntawm 15KV, 25KV, thiab 35KV (xws li LBI200 series) thiab ua raws li IEEE 386 tus qauv. Nws ua haujlwm raws li qhov sib txuas ntawm lub transformer lub hauv paus windings thiab sab nraud tis cables, featuring ib tug kaw, ntsaws{10}}nyob rau hauv tsim nrog rwb thaiv tsev ntaub ntawv xws li epoxy los yog iav-inforced nylon resin kom zoo dua hluav taws xob rwb thaiv tsev thiab mechanical stability. Qhov bushing no tiv thaiv cov roj transformer to thiab ya raws / plua plav nkag thaum txo qis arc flash txaus ntshai thaum tu, txhawb nqa kev nyab xeeb{13}}kev ua haujlwm tawg thiab teb- hloov ua haujlwm tau zoo rau kev faib hluav taws xob sab nraum zoov.

03 Kev Xeem

Rwb thaiv tsev Resistance Measurement yog ib qho kev ntsuam xyuas tseem ceeb rau cov ntaub qhwv -mounted transformers, ua los ntsuam xyuas qhov ncaj ncees thiab zoo ntawm cov rwb thaiv tsev ntawm windings thiab nruab nrab windings thiab hauv av. Feem ntau ua tau siv lub megohmmeter (Megger), qhov kev sim siv lub siab DC voltage los ntsuas qhov tsis kam ntawm cov rwb thaiv tsev. Kev nyeem ntawv siab, ruaj khov qhia tau hais tias muaj zog dielectric zog thiab noj qab nyob zoo, rwb thaiv tsev qhuav, thaum tus nqi qis los yog poob qis tuaj yeem ua rau muaj teeb meem xws li kev ya raws, kev sib kis, rwb thaiv tsev laus, lossis kev puas tsuaj rau lub cev. Qhov kev ntsuam xyuas niaj hnub no yog qhov tseem ceeb rau kev saib xyuas kev kwv yees, pab tiv thaiv kev ua tsis tiav, ua kom cov neeg ua haujlwm muaj kev nyab xeeb, thiab txuas ntxiv lub neej ua haujlwm ntawm lub tshuab hloov pauv hauv lub network faib.
