YBM ntse integrated substation

Qhov no ntse integrated transformer substation yog lub teb chaws hom American box substation tsim los ntawm JONCHN tuam txhab.Raws li ib qho tseem ceeb ntawm cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob cable, nws yog ib qho kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob siab, kev tiv thaiv, kev hloov hluav taws xob thiab hluav taws xob faib hluav taws xob, uas yog siv dav hauv nroog thiab nyob deb nroog.Lub high voltage load hloov thiab high voltage fuse yog muab tso rau hauv lub transformer roj, yog li cov khoom no muaj ob tug qauv ntawm ib lub thawv thiab faib lub thawv nrog lub transformer lub cev.Lub thawv roj yog cov qauv ntim puv nrog roj ntsuas ntsuas, ntsuas roj qib ntsuas, ntsuas lub siab, lub siab nyem valve thiab roj ntws valve los saib xyuas cov haujlwm ntawm lub tshuab hloov pauv.Cov khoom no muaj peb hom kev siv fais fab hom nplhaib network hom, hom davhlau ya nyob twg thiab hom fais fab.Txhawm rau ua kom cov khoom ua tau raws li qhov xav tau tiag tiag ntawm daim phiaj hluav taws xob hauv Suav teb zoo dua, JONCHN Lub Tuam Txhab txhawb nqa ntsaws rub hom fuse thiab qhov sib txuas ntawm fuse hlau tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm cov roj transformer.Raws li qhov nyuaj ntawm qhov kev xav tau ntawm qhov tsis tshua muaj hluav taws xob tawm, cov khoom no muaj peb hom kev thaiv - hom qauv, hom kev txhawb zog thiab kev sib xyaw ua ke, vim li ntawd, cov neeg siv khoom thiab cov neeg tsim qauv muaj kev xaiv ntau dua.

Cov yam ntxwv zoo

Lub moj khaum qauv ntawm lub thawv enclosure yog ua los ntawm channel steel thiab lub kaum sab xis steel nrog ntau dua txhua yam muaj zog.lub enclosure yog ua los ntawm txhuas alloy phaj nrog du nto, zoo nkauj txheej txheem thiab zoo anti corrosion kev ua tau zoo, lub hauv paus ntawm lub thawv lub cev yog 300-600mm siab tshaj hauv av.Txhua lub qhov rooj ntawm lub thawv kaw yog qhib rau sab nraud, thiab qhib. lub kaum sab xis loj dua 90 ° thiab tau teeb tsa nrog cov khoom siv hauv qhov chaw, tes tuav, lub qhov rooj zais cia, nrog rau cov khoom siv hauv cov xauv uas muaj cov haujlwm ntawm kev tiv thaiv los nag, tiv thaiv kev thaiv thiab xeb.lub thawv lub cev yog ntawm tag nrho-sealed tub sab nyiag-pov thawj qauv.kom paub tseeb tias kev ua haujlwm nyob rau hauv ib puag ncig huab cua kub, qhov kub ntawm tag nrho cov khoom siv hluav taws xob tsis tuaj yeem siab tshaj qhov siab tshaj plaws, thiab lub thawv lub cev muaj qhov qhib qhov cua txaus thiab ntsuas cua sov.lub thawv lub cev ntawm prefabricated substation yog tsim los nrog tshwj xeeb grounding conductor, nyob rau hauv uas muaj ntau tshaj 2 taag txuas terminals txuas nrog rau hauv av network thiab nyob rau hauv uas muaj ib tug pom tseeb grounding cim.lub hauv paus davhlau ya nyob twg yog tooj liab ntsia liaj qhov rooj, txoj kab uas hla uas tsis tsawg tshaj li 12 hli.Tus neeg xyuas pib hauv av yog tsim los ntawm tooj liab sawb, qhov ceev tam sim no tsis siab tshaj 200A / ㎜² thiab ntu ntu uas tsis pub tsawg dua 30㎜², thiab nws tau lees paub tias tsis muaj cua sov thiab tsis muaj qhov phem cuam ​​tshuam rau kev nyab xeeb ntawm cov khoom nyob ib puag ncig thaum qhov siab tshaj plaws luv luv tam sim no dhau mus.lub dynamic thiab thermal stability tam sim no uas tshwj xeeb grounding conductor endures yuav tsum tau ua ke nrog cov grounding hom ntawm high voltage fais fab faib khoom.
