800 KVA Tsawg Voltage Qhuav Hom Transformer-6.6/0.55 KV|South Africa 2025

01 General

1.1 Project Description

800kVA cam khwb cia coil qhuav hom transformer raug xa mus rau South Africa hauv 2025. Lub zog ntsuas ntawm lub transformer yog 800 kVA nrog KNAN / KNAF txias. Thawj qhov hluav taws xob yog 6.6 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.55 kV, lawv tsim ib pawg vector ntawm Dyn11.

Hauv lub ntiaj teb niaj hnub no, qhov chaw ua lag luam txuas ntxiv, kev nyab xeeb, thiab kev siv hluav taws xob yog qhov tseem ceeb, cov cam khwb cia qhuav-hom transformer sawv ua lub hauv paus ntawm lub tshuab hluav taws xob niaj hnub. Engineered rau siab tshaj plaws kev ntseeg, cov transformers muab unparalleled kev thaj yeeb ntawm lub siab. Lawv cov nplaim taws-retardant, epoxy-encased tsim tshem tawm cov teeb meem hluav taws, tso cai rau kev nyab xeeb kev teeb tsa ncaj qha nyob ib sab ntawm koj cov khoom tseem ceeb, uas txuag qhov chaw muaj txiaj ntsig thiab txo nqi kev teeb tsa.

Nrog rau kev tsom mus rau kev ruaj khov thiab tsis tshua muaj nqi ntawm cov tswv cuab, peb cov cam khwb cia coil transformers muaj qhov ua tau zoo - qauv tsim uas txo qis zog poob, ua rau muaj kev txuag nyiaj ntau. Lawv yuav tsum tsis muaj kev saib xyuas zoo thiab tsim los tiv thaiv cov kev lag luam nyuaj tshaj plaws, ua kom lub zog tsis muaj kev cuam tshuam rau koj cov haujlwm tseem ceeb tshaj plaws -los ntawm kev tsim cov nroj tsuag thiab cov phiaj xwm hluav taws xob tauj dua tshiab mus rau cov chaw lag luam thiab cov pej xeem infrastructure. Xaiv cam khwb cia coil thev naus laus zis rau qhov ntse dua, muaj kev nyab xeeb dua, thiab muaj zog dua kev daws teeb meem.

02 Kev tsim khoom

2.1 Core

Cov tub ntxhais hlau yog tsim los ua kom zoo rau kev ua haujlwm ntawm qhov tsis tshua muaj flux, txo qhov tsis muaj -load poob thiab ua kom muaj kev ua haujlwm ntsiag to. Txhawm rau tiv thaiv txoj kev eddy tam sim no, cov laminations nyias nyias yog coated nrog ib txheej insulating. Tom qab stacking, cov tub ntxhais yog ruaj khov thiab ruaj khov nyob rau hauv ib qho chaw, tshem tawm cov kev pheej hmoo ntawm cov circulating tam sim no thiab ua kom muaj kev nyab xeeb, txhim khu kev qha, thiab lub zog- ua haujlwm tau zoo.

2.2 Cua txias

Rau cam khwb cia coil qhuav hom transformer windings, conductors yog teem nyob rau hauv ib qho kev txiav txim thiab insulated nrog iav fiber ntau cov ntaub ntawv ua ntej, tom qab los ntawm lub tshuab nqus tsev siab casting nrog tshav kub-resistant epoxy resin compound. Kev kho cua sov ua kom muaj kev sib cog lus, cov khoom siv rwb thaiv tsev uas tsis yog tsuas yog muaj lub zog dielectric siab thiab thermal conductivity rau cov cua sov kom zoo, tab sis kuj muaj zog tiv thaiv - pa phem thiab tiv thaiv - muaj peev xwm corrosion, haum rau ntau yam kev siv sab hauv tsev thiab sab nraum zoov.

 

2.3 Lub Rooj Sib Tham Kawg

Rau cam khwb cia coil qhuav hom transformer los ua ke, cov tub ntxhais hlau yog thawj qhov chaw ruaj khov. Ua ntej- cam khwb cia windings yog ces sib sau ua ke rau hauv cov tub ntxhais nrog rwb thaiv tsev tiv thaiv lawv txoj hauj lwm. Kev sib txuas ua ke ntawm windings thiab sab nraud terminals yog tsim, thiab cov tshuab cua txias (xws li cov kiv cua axial) tau ua ke. Tom qab ntawd lub kaw lus txuas nrog, thiab tshaj tawm- kev tshuaj xyuas cov khoom sib dhos- suav nrog cov rwb thaiv tsev tiv thaiv thiab kev ntsuas qhov sib piv- tau ua kom paub meej tias lub tuam tsev muaj kev ncaj ncees thiab kev ua tau zoo.

 

 

03 Kev Xeem

Kev ntsuam xyuas rau 800kVA-6.6/0.55kV cam khwb cia coil qhuav hom transformer ua raws li IEC 60076-1, 60076-3 thiab 60076-11 cov qauv, npog cov khoom niaj hnub: winding resistance ntsuas (unbalance rate Less than 2%), qhov sib npaug ntawm qhov ntsuas hluav taws xob Kev sib txawv ± 1/10), luv luv-circuit impedance / load poob thiab tsis muaj load poob / tam sim no kev xeem, thov voltage test (HV 20kV / 60s, LV 5kV / 60s), induced voltage withstand test (1.1kV, 150Hz, 40s), thiab ib nrab paug xeem (Cp); max Less tshaj 10 tag nrho cov ntsuas ntsuas raws li qhov yuav tsum tau ua, nrog rau "Pass" xaus.

04 Packing thiab Shipping

4.1 Ntim

Rau cam khwb cia coil qhuav hom transformers, ntoo thawv ntim nta ntxiv cov ces kaum thiab steel strapping ntawm lub crate sab nrauv. Sab hauv, kev cai ntoo kev txhawb nqa yog siv los ua kom haum nrog lub transformer lub hauv paus, ua npuas ncauj buffers sau qhov khoob ntawm lub cev thiab crate, thiab cov plua plav kaw - cov ntaub ntawv pov thawj ntxiv - tsim nyog rau kev ruaj ntseg rau lub sijhawm ntev - nrug lossis hnyav - thauj khoom.

 

4.2 Shipping

Rau cov cam khwb cia coil qhuav hom transformer, kev thauj mus los yog npaj raws li CIF nqe lus rau Durban chaw nres nkoj. Cov ntoo - ntim transformer yog loaded rau hauv shipping ntim; tus neeg muag khoom dais dej hiav txwv freight thiab procures marine cargo insurance npog qhov yooj yim txaus ntshai. Nws yuav muaj kev nyab xeeb thauj mus rau Durban chaw nres nkoj, nrog tus neeg muag khoom ua tiav cov luag haujlwm xa khoom thaum thauj khoom ntawm lub nkoj.

 

05 Site thiab Summary

Kev sib koom ua ke cov txheej txheem cam khwb cia siab tshaj plaws nrog kev nyab xeeb ntawm qhov qhuav- hom kev tsim kho, peb cov cam khwb cia hlau qhuav hom transformer hais txog qhov kev thov tseem ceeb rau kev ruaj khov, tsis tshua muaj - kev pheej hmoo fais fab kev faib tawm. Zoo meej rau ib puag ncig uas cov roj- ntim cov chav ua haujlwm tsis zoo, nws ua tau zoo nyob rau hauv qhov hnyav lossis rhiab heev thaum ua tau raws li cov qauv ntsuas thoob ntiaj teb. Ntau tshaj li ib feem, nws yog lub pob txha ruaj khov ntawm koj cov khoom siv hluav taws xob- txhawb nqa los ntawm kev ua tau zoo los txhawb koj txoj haujlwm ntev -.
