15 MVA Step Up Fais Fab Transformer-4.16/69 kV|Guyane xyoo 2023

Peb lub tuam txhab txais yuav high-conductive volt-oriented txias- dov silicon steel ntawv, tsis muaj- qhov khi, ncej qauv, d- zoo li tus yoke qauv rau coil es tsis txhob loj - cheeb tsam platform, stepped pob qij txha. Cov tub ntxhais muaj me me burr thiab qis lamination coefficient. Qhov tsis muaj-load poob, tsis muaj-load tam sim no thiab lub suab nrov tau txo qis los ntawm ntau- theem pob qij txha ntawm cov tub ntxhais hlau.

1. Nruam winding tsim: Lub tangle ib tug nruam hom thiab cov phaj puab ib tug nruam hom tsim yog siv, uas yuav pab txhim kho lub longitudinal capacitance tis ntawm lub kauj nyob rau hauv lub impulse voltage. Qhov kev tsim no tuaj yeem txo qhov concentration ntawm cov hluav taws xob hauv hluav taws xob, kom lub kauj muaj hluav taws xob zoo dua ntawm kev kub siab.

2. Cov qauv kev coj noj coj ua ntawm cov roj: cov qauv coj cov roj ncig yog siv los pab txo qis cua kub nce. Qhov kev tsim no tswj qhov kub hauv lub kauj thiab pab txhim kho kev nyab xeeb thiab ruaj khov ntawm transformer.

1. Sealing kev ua tau zoo: Lub tank roj tau ntim nrog kev txwv nres kom ntseeg tau tias cov roj hluav taws xob hloov hluav taws xob tuaj yeem raug kaw zoo hauv cov roj tank kom tsis txhob xau thiab oxidation ntawm cov roj insulating.

2. Anti- kev kho corrosion: Lub tank roj yog ua los ntawm corrosion- cov ntaub ntawv resistant, thiab cov xim yuav tsum tau siv rau cov khoom siv hauv tsev yog siv los txhim kho corrosion kuj ntawm cov roj tank thiab txuas lub neej kev pab cuam.

3. Kev kuaj xyuas cov dej xau: cov vuam thiab lub foob ntawm lub tank tau dhau los ua peb qhov kev kuaj pom cov pa tawm (fluorescence, zoo siab, qhov tsis zoo ntawm qhov ntsuas qhov tsis zoo) txhawm rau xyuas kom nruj thiab kev nyab xeeb.

Kev sib dhos zaum kawg ntawm cov roj-immersed fais fab transformer ua los ntawm lub tuam txhab transformer feem ntau muaj ob peb kauj ruam tseem ceeb:

1. Core Assembly: Cov tub ntxhais sib dhos feem ntau yog thawj kauj ruam hauv kev sib dhos zaum kawg. Qhov no muaj xws li stacking thiab clamping ntawm transformer core, uas yog tsim los ntawm high - qib hluav taws xob steel laminations. Cov tub ntxhais yuav tsum tau sib sau ua ke kom meej meej kom paub meej cov khoom sib nqus zoo thiab cov tub ntxhais poob tsawg.

2. Windings Installation: Cov txheej txheem suav nrog kev txhim kho qhov siab -voltage (HV) thiab qis-voltage (LV) windings mus rau qhov tseem ceeb. Cov windings feem ntau yog insulated tooj liab conductors uas tau ua tib zoo muab tso, txheej, thiab txuas raws li tus qauv transformer.

3. Tank thiab Radiator Installation: Lub tank transformer, nrog rau cov kev cuam tshuam cov radiators los yog txias fins, yog ntsia rau theem no. Lub tank muab vaj tse rau cov tub ntxhais thiab windings thiab tuaj yeem kaw kom muaj cov roj insulating.

4. Rwb thaiv tsev, kev sib txuas, thiab cov khoom siv: Cov khoom siv rwb thaiv tsev, xws li bushings, leads, kais changers, thiab lwm yam khoom siv tau nruab thiab txuas nrog cov windings. Kev rwb thaiv tsev thiab kev txhawb nqa ntxiv tau ntxiv los ua kom muaj kev nyab xeeb thiab txhim khu kev qha.

5. Roj Filling thiab Sealing: Lub transformer yog ntim nrog insulating roj los ntawm kev ua tib zoo tswj. Thaum ua tiav, lub transformer raug kaw kom tsis txhob ya raws ingress thiab tswj cov roj kev ncaj ncees.

Kev ntim khoom thiab kev thauj mus los ntawm cov roj-immersed fais fab transformer uas tsim los ntawm lub tuam txhab transformer muaj ob peb kauj ruam tseem ceeb los xyuas kom meej qhov kev nyab xeeb thiab ruaj ntseg ntawm cov khoom. Hauv qab no yog cov lus piav qhia dav dav ntawm cov txheej txheem:

1. Kev ntim khoom: Thaum lub tshuab hloov pauv tau dhau los ua qhov kawg, suav nrog kev kuaj thiab kev kuaj xyuas zoo, nws tau npaj rau kev ntim khoom. Cov khoom siv hluav taws xob hloov pauv, suav nrog lub tank, tub ntxhais, windings, thiab cov khoom siv sib txuas, tau ua tib zoo saib xyuas thiab tiv thaiv kev thauj mus los. Cov khoom ntim khoom, xws li ntoo crates, ua npuas ncauj padding, thiab strapping, raug xaiv los muab cov cushioning txaus thiab kev tiv thaiv.

2. Kev Tiv Thaiv Kev Tiv Thaiv thiab Kev Tiv Thaiv Corrosion: Cov khoom siv hluav taws xob hloov pauv tau raug kho nrog cov tshuaj tiv thaiv tsim nyog los tiv thaiv corrosion thaum thauj thiab khaws cia.

Kev ruaj ntseg rau kev thauj mus los: Cov khoom siv hluav taws xob hloov pauv tau ruaj ntseg hauv lub ntim kom tsis txhob txav mus los thiab ua kom muaj kev ruaj ntseg thaum lub sijhawm thauj mus los. Kev ruaj ntseg thiab sib npaug yog tswj xyuas kom tsis txhob muaj kev ntxhov siab rau txhua qhov ntawm lub transformer.

Kev Qhia Txog Tus Kheej thiab Cov Ntaub Ntawv: Txhua qhov ntim cov khoom tau sau npe, thiab cov ntaub ntawv ntxaws ntxaws tau npaj, suav nrog cov npe ntim khoom, cov lus qhia thauj khoom, thiab cov ntawv tso cai lossis ntawv pov thawj xav tau rau kev thauj mus los.

Kev Thauj Khoom thiab Kev Thauj Khoom: Cov khoom ntim tau ntim rau hauv cov tsheb thauj khoom tsim nyog, xws li cov tsheb thauj mus los lossis cov thawv thauj khoom, siv cranes lossis lwm yam khoom siv. Kev thauj mus los tshwj xeeb yuav xav tau rau cov hloov pauv loj lossis hnyav.

Kov thiab Unloading: Thaum lub sij hawm thauj mus los, lub transformer Cheebtsam yog ua tib zoo saib xyuas kom tsis txhob muaj kev puas tsuaj. Thaum tuaj txog ntawm qhov chaw, saib xyuas thaum lub sijhawm thauj khoom kom muaj kev nyab xeeb thiab kev tuav tau zoo
