Lub ntsiab sib txawv thiab qhov zoo thiab qhov tsis zoo ntawm qhuav hom Transformers Thiab Roj-immersed Fais Fab Transformer

GNEE Steel roj puv tis transformers

Kev tsim kho ntawm transformers hauv kev tsim hluav taws xob engineering tuaj yeem hais tias yog ib feem tseem ceeb heev. Ntawm lawv, peb feem ntau hnov ​​​​mob qhuav-hom transformers (hu ua qhuav-hloov) thiabroj immersed hwj chim transformers(xws li kev hloov roj). Yog li dab tsi yog qhov txawv ntawm qhov qhuav-hom transformers thiab roj immersed hwj chim transformers nyob rau hauv lub hwj chim engineering tsim? Lawv qhov zoo thiab qhov tsis zoo yog dab tsi?

 

Qhov loj tshaj qhov sib txawv ntawm roj-immersed hwj chim transformers thiabqhuav hom transformersyog "roj". Txij li cov roj yog kua thiab muaj fluidity, roj-impregnated fais fab transformer yuav tsum muaj lub casing. Sab hauv ntawm lub casing yog transformer roj. Cov roj yog immersed nyob rau hauv lub kauj ntawm lub transformer. Lub kauj ntawm lub transformer tsis pom los ntawm sab nraud. Lub tshuab ziab khaub ncaws qhuav tsis muaj lub tsho sab nrauv tsis muaj roj. Nws tuaj yeem pom cov kauj ntawm lub transformer ncaj qha; kuj tseem muaj cov yam ntxwv uas muaj cov roj hauv ncoo ntawm cov roj-impregnated fais fab transformer, thiab cov roj transformer khaws cia rau hauv, tab sis tam sim no cov roj tshiab-immersed transformer kuj tsis muaj roj hauv ncoo.

 

Lawv yog tag nrho cov fais fab transformers, thiab yuav muaj hlau cores rau lub magnetic Circuit Court ua rau lub windings ntawm lub Circuit Court. Qhov sib txawv loj tshaj plaws yog nyob rau hauv "roj" thiab "qhuav". Uas yog hais, qhov nruab nrab cua txias ntawm ob yog txawv. Cov qub siv cov roj hloov pauv (thiab tau kawg lwm cov roj xws li roj) raws li qhov nruab nrab cua txias thiab rwb thaiv tsev, thiab tom kawg siv cua lossis lwm yam roj xws li SF6 ua qhov nruab nrab cua txias. Kev hloov roj yog tso lub cev uas muaj cov tub ntxhais hlau thiab winding nyob rau hauv lub tank roj uas muaj cov roj transformer. Qhuav feem ntau yog kaw cov tub ntxhais thiab windings nrog epoxy resin. Kuj tseem muaj hom tsis-encapsulated uas siv niaj hnub no. Cov windings yog impregnated nrog tshwj xeeb insulating ntawv los tiv thaiv lub windings los yog core kom tsis txhob ntub.

 

Txhawm rau kom yooj yim rau cov cua sov dissipation, uas yog, rau qhov yooj yim ntawm cov roj insulating hauv cov dej ntws, lub dab dej kub yog tsim los sab nraum cov roj immersed fais fab transformer, ib yam li lub dab dej kub. Lub tshuab hluav taws xob qhuav tsis muaj lub tshuab hluav taws xob no, thiab cov cua sov yog txias los ntawm cov kiv cua hauv qab ntawm transformer kauj.

 

Roj immersed hwj chim transformers feem ntau ntsia sab hauv tsev los yog sab nraum zoov nyob rau hauv cais transformers rau lub hom phiaj tiv thaiv hluav taws. Lub tshuab ziab khaub ncaws qhuav yog ntsia tau rau hauv tsev thiab feem ntau yog ntsia hauv chav fais fab.

 

Nyob rau hauv cov nqe lus ntawm cov zis thiab ntau npaum, tam sim no qhuav voltage theem tsuas yog 35kV. Nws lub peev xwm me me piv rau kev hloov roj, txog 2500kVA. Ntxiv mus, vim hais tias cov txheej txheem ntawm qhuav-hom transformers yog ntau nyuaj thiab kim tshaj li roj transformers ntawm tib voltage theem thiab muaj peev xwm, cov roj transformer yog tseem ntau nyob rau hauv cov nqe lus ntawm cov roj. Txawm li cas los xij, vim yog kev tiv thaiv ib puag ncig ntawm kev hloov pauv qhuav, nplaim hluav taws kub, kev cuam tshuam thiab lwm yam zoo, nws feem ntau siv sab hauv tsev thiab lwm qhov chaw siv hluav taws xob siab thiab kev faib khoom, xws li tsev so, tsev ua haujlwm, cov tsev siab siab thiab lwm yam. .

 

Nws tuaj yeem pom tau tias cov transformer qhuav thiab roj transformer txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Cov roj transformer yog tus nqi qis thiab yooj yim los tswj, tab sis nws yog flammable thiab tawg. Qhuav transformers tuaj yeem ntsia tau rau hauv nruab nrab ntawm cov khoom thauj vim lawv qhov hluav taws kub zoo los txo qhov tsis muaj zog thiab lub zog poob. Txawm li cas los xij, cov tshuab ziab khaub ncaws qhuav yog kim, loj, ya raws thiab pov thawj plua plav, thiab muaj suab nrov.

 

 

Tom ntej no, cia peb xaus qhov sib txawv uas tau hais los saum toj no rau hauv xya lub ntsiab lus hauv qab no:

1. Kev tshwm sim

Ob lub pob khoom sib txawv. Lub tshuab hluav taws xob qhuav tuaj yeem pom ncaj qha rau cov tub ntxhais hlau thiab lub kauj, thaum cov roj-impregnated fais fab transformer tuaj yeem pom tsuas yog sab nrauv ntawm lub transformer;

 

2. Cov ntawv txhuas sib txawv

Feem ntau ntawm cov tshuab ziab khaub ncaws siv cov roj hmab silicone roj hmab, thaum feem ntau cov roj impregnated fais fab transformers siv porcelain bushing;

 

3. Muaj peev xwm thiab qhov hluav taws xob sib txawv

Qhuav hom transformer feem ntau haum rau kev faib hluav taws xob, muaj peev xwm feem ntau qis dua 2000kVA thiab qhov hluav taws xob ntawm 10kV thiab qis dua, thiab qee qhov ntawm lawv tuaj yeem ua tiav 35kV voltage theem; thaum roj immersed fais fab transformer tuaj yeem ua tiav tag nrho cov peev txheej uas yuav tsum tau muaj thiab qib voltage kuj tuaj yeem ua tiav tag nrho cov voltages; rau UHV 1000kV kab nyob rau hauv kev tsim kho nyob rau hauv Tuam Tshoj, roj immersed hwj chim transformer yuav tsum tau siv.

 

4. Rwb thaiv tsev thiab cua sov dissipation yog txawv

Qhuav hom transformers feem ntau insulated nrog resin, cia siab rau tej huab cua-txias, thiab loj-muaj peev xwm txias los ntawm cov kiv cua; Thaum cov roj-impregnated fais fab transformers yog insulated los ntawm insulating roj, thiab lub puab kauj ntawm lub transformer yog recycled los ntawm insulating roj nyob rau hauv lub transformer kom dissipate tshav kub.

 

5. Cov chaw siv tau

Qhuav hom transformers feem ntau yog siv nyob rau hauv qhov chaw uas yuav tsum tau "tiv thaiv hluav taws thiab tawg-pov thawj", thiab yuav tsum tau siv nyob rau hauv dav dav cov tsev loj thiab high-sawv vaj tse; roj impregnated fais fab transformers feem ntau yog siv nyob rau hauv sab nraum zoov qhov chaw uas "kev huam yuaj roj pas dej ua ke" yog khawb vim roj gushing los yog to tom qab "kev huam yuaj".

 

6. Txawv load bearing muaj peev xwm

Feem ntau, qhuav-hom transformer yuav tsum ua haujlwm ntawm lub peev xwm ntsuas, thaum cov roj immersed fais fab transformer muaj peev xwm zoo dua.

 

7. Tus nqi sib txawv

Rau tib lub peev xwm transformer, tus nqi yuav khoom ntawm qhuav-hom transformer yog ntau dua li cov roj immersed fais fab transformer.
