Q: Dab tsi yog transformers ntawm qhov hluav taws xob ncej ua?
A: Kev txo qis hluav taws xob: Lub luag haujlwm tseem ceeb ntawm lub tshuab hluav taws xob hluav taws xob yog hloov siab - hluav taws xob hluav taws xob tau txais los ntawm daim phiaj hluav taws xob mus rau qhov hluav taws xob qis tsim nyog siv rau hauv cov chaw lag luam thiab chaw nyob.
Kev rho tawm: Fais fab ncej transformers yog tsim los muab kev sib cais ntawm thawj winding (txuas mus rau qhov siab -voltage qhov chaw) thiab qhov thib ob winding (txuas mus rau qhov qis-voltage output). Qhov kev sib cais no yog qhov tseem ceeb rau kev nyab xeeb thiab tiv thaiv kev cuam tshuam ntawm circuits.
Fais fab Fais Fab: Ncej-mounted transformers ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob mus rau cov nroog thiab thaj chaw deb deb nroog. Lawv ua raws li tus neeg nruab nrab hauv cov phiaj xwm hluav taws xob, kom ntseeg tau tias hluav taws xob mus txog ntau qhov chaw kom ua tau raws li qhov xav tau ntawm lub zog sib txawv rau cov teeb pom kev zoo, khoom siv, thiab lwm yam khoom siv hluav taws xob.
Q: ncej-mounted transformers yog dab tsi?
A: Lub zog ncej transformer feem ntau yog tsim los ntawm cov tub ntxhais hlau thiab winding. Nws yog txoj kev sib nqus channel ntawm cov tub ntxhais hlau transformer, thiab winding yog ib feem ntawm lub transformer, uas yog ua los ntawm enameled nyob ntawm tej nrog ib tug tej yam kev mob ntawm lem. Thaum nws txuas nrog lub hwj huam mov, peb hu nws lub ntsiab winding, uas tseem hu ua thawj winding. Txuas nrog lub load, peb hu nws thib ob winding, kuj hu ua theem nrab winding lossis theem nrab winding. Cov ntaub ntawv tseem ceeb ntawm cov tub ntxhais hlau hlau muaj xws li hom tub ntxhais thiab hom plhaub. Lub hauv paus tseem ceeb ntawm lub transformer nrog cov qauv tseem ceeb yog surrounded los ntawm windings. Cias muab, lub winding nyob ib ncig ntawm cov tub ntxhais hlau, yog li cov qauv yog yooj yim, thiab kev sib dhos thiab rwb thaiv tsev yog ib qho yooj yim, yog li lub transformer feem ntau siv cov txheej txheem tseem ceeb. Lub plhaub qauv yog tias cov tub ntxhais hlau nyob ib puag ncig lub winding. Lub plhaub- hom transformer muaj lub zog txhua yam thiab cov hniav raug, tab sis nws cov txheej txheem tsim khoom yog qhov nyuaj thiab siv cov ntaub ntawv ntau dua. Nws yog feem ntau tsuas yog siv nyob rau hauv qis -voltage siab- tam sim no transformers los yog me me - muaj peev xwm transformers.
Q: Vim li cas cov ncej mounted substations nrov heev?
A: Qhov kev tsim substation no yog qhov pheej yig tshaj plaws, tsawg tshaj plaws, thiab yooj yim rau nruab. Tsis muaj qhov yuav tsum tau ua rau lub tsev rau lub tsev no substation. Tus ncej no-mounted substation muab hluav taws xob feem ntau rau peb lub tsev.
Q: Vim li cas transformers ntawm ncej?
A: Ncej-mounted transformers, raws li lub npe qhia, yog ntsia rau ntawm cov khoom siv hluav taws xob, feem ntau pom nyob rau hauv cov chaw nyob deb nroog lossis thaj chaw nyob. Lawv ua haujlwm los ntawm kev sib txuas ntawm cov nyiaj siv ua haujlwm siab - cov kab hluav taws xob thiab qis dua - cov kab hluav taws xob faib hluav taws xob.
Q: Lub hom phiaj tseem ceeb ntawm pad mounted lossis ncej mounted faib transformers yog dab tsi?
A: Ob leeg ncej-mounted thiab ncoo-mounted transformers hloov lub siab 'primary' voltage ntawm lub overhead lossis underground faib kab mus rau qis 'secondary' lossis 'utilization' voltage hauv lub tsev. Thawj cov xaim xaim xaim siv peb -theem system.
Q: Puas yog ncej mounted transformers muaj kev nyab xeeb?
A: Ncej-mounted transformers yog siab- cov khoom siv hluav taws xob hluav taws xob uas ua rau muaj kev pheej hmoo ntawm hluav taws xob poob lossis hluav taws xob. Insulating hnab looj tes, dielectric khau, thiab lwm yam khoom siv hluav taws xob PPE muab kev tiv thaiv kev tiv thaiv, txo qhov kev pheej hmoo ntawm hluav taws xob raug mob.
Q: Cov ncej mounted transformers ua li cas?
A: Fais Fais Fais Fais Fais Fais faib: Ncej-mounted transformers ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob mus rau cov nroog thiab cov chaw nyob deb nroog. Lawv ua raws li tus neeg nruab nrab hauv cov phiaj xwm hluav taws xob, kom ntseeg tau tias hluav taws xob mus txog ntau qhov chaw kom ua tau raws li qhov xav tau ntawm lub zog sib txawv rau cov teeb pom kev zoo, khoom siv, thiab lwm yam khoom siv hluav taws xob.
Q: Dab tsi yog ncej mounted transformers puv nrog?
A: Cov tub ntxhais thiab cov coil sib dhos yog muab tso rau hauv lub tank cylindrical steel uas muaj cov roj ntxhia qib siab - qib roj ntxhia tshwj xeeb tshaj yog ua kom zoo rau kev siv hluav taws xob. Cov roj no muab ob qho tib si hluav taws xob rwb thaiv tsev thiab cua txias rau cov windings ntawm transformer.
Q: Dab tsi yog qhov kev nyab xeeb ntawm tus ncej-mounted transformer?
A: 10 feet
Ncej-mount transformers yuav tsum tau kho tib yam, raws li ib tug overhead fais fab kab. Ib txwm tswj kom muaj kev nyab xeeb ntawm yam tsawg kawg 3 meters (10 ko taw) los ntawm txhua tus ncej-mount transformer.
Q: Puas yog ncej mounted transformers roj puv?
A: Ib zaug -theem overhead transformers tuaj yeem sau nrog cov txheej txheem hluav taws xob qib ntxhia insulating roj lossis hluav taws kub- tiv taus FR3 kua.
Q: Nws raug nqi npaum li cas los muab lub transformer rau ntawm tus ncej?
A: Lub tsev hloov pauv hauv tsev raug nqi $ 3,000 txog $ 20, 000+ ntsia, nyob ntawm qhov loj thiab hom. Kev khiav cov kab hluav taws xob tshiab yuav xav tau kev txhim kho ib lossis ntau lub transformers, nyob ntawm qhov kev ncua deb ntawm cov cuab yeej mus rau qhov ze tshaj plaws transformer uas twb muaj lawm. Feem ntau cov tuam txhab xav tau lub tshuab hloov pauv hauv 150 'ntawm lub tsev.
Q: Tus ncej transformers tau ntsuas li cas?
A: Tus qauv ib theem transformer fais fab ntsuas yog los ntawm 5-167kVA. Daelim tuaj yeem kho raws li koj xav tau, qhov siab tshaj plaws muaj peev xwm ncav cuag 333kVA. Cov lus hauv qab no yog tus qauv ntawm ib theem transformer specifications.
Q: Dab tsi yog qhov txawv ntawm ncej mounted thiab ncoo -mounted transformer?
A: Yog tias ntsia rau ntawm tus ncej hluav taws xob, lawv hu ua ncej-mount transformers. Yog hais tias cov kab xa tawm nyob rau hauv av los yog hauv av, cov khoom siv hluav taws xob sib faib tau nruab rau ntawm cov pob zeb ua vaj tse thiab kaw rau hauv cov rooj plaub hlau, yog li hu ua faib kais pad -mount transformers.
