GNEE Steel faib thiab fais fab transformer
Lub transformer yog ib qho khoom siv passive uas hloov hluav taws xob hluav taws xob los ntawm ib qho hluav taws xob mus rau lwm lub voj voog lossis ntau lub voj voog.
Nyob ntawm tus qauv tsim, kev ua haujlwm, lub hom phiaj ntawm kev siv thiab winding configuration txawv lawv rau kev siv sib txawv xws li pej xeem thiab kev lag luam (hauv tsev thiab kev lag luam).
Hauv tsab xov xwm no, peb yuav qhia qhov sib txawv tseem ceeb ntawmfais fab mov transformersthiabfaib transformers.
Cov ntsiab lus
1. Lub hwj chim transformer yog dab tsi?
2. Dab tsi yog qhov kev faib tawm transformer?
3. Qhov sib txawv ntawm lub hwj chim transformers thiab tis transformers
a. Muaj nuj nqi siv
b. Transformer loj thiab qib rwb thaiv tsev
c. Kev ua haujlwm siab tshaj plaws
1. Lub hwj chim transformer yog dab tsi?
Lub zog transformernyob rau hauv ib qho chaw tsim khoom lossis chaw nres tsheb nrog lub siab heev MVA (mega Volt-Ampere) siv los xa cov hluav taws xob hluav taws xob siab dhau ntawm cov kab hluav taws xob mus rau qhov chaw faib khoom yog hu ua transmission transformer.
Lawv feem ntau tshaj 200 MVA nrog qhov ntsuas hluav taws xob ntawm 400kV, 200kV, 110kV, 66kV, 33kV, thiab lwm yam. Lawv tau tsim los ua haujlwm ntawm kev ua haujlwm tag nrho nrog kev ua haujlwm siab tshaj plaws.
Lub hom phiaj tseem ceeb ntawm kev hloov pauv hloov pauv yog txhawm rau nce qib qis qis mus rau qib siab voltage thiab xa mus los ntawm cov kab xa mus rau qhov chaw faib khoom rau kev ua haujlwm ntxiv.
2. Dab tsi yog qhov kev faib tawm transformer?
Fais fab mov transformertseem hu ua ib tug raug rho tawm transformer. Lub luag haujlwm tseem ceeb ntawm lub tshuab hluav taws xob no yog hloov cov hluav taws xob siab rau hauv cov qauv hluav taws xob zoo li 240/120 V rau kev siv hluav taws xob faib. Hauv kev faib khoom, muaj ntau hom transformers, xws li ib-theem, 3-theem, underground, ncoo-mounted, thiab ncej-mounted transformers.
Lub hom phiaj ntawm kev siv transformer:
• Qhov no transformer hloov los ntawm high voltage mus rau tsawg voltage, siv nyob rau hauv cov tsev thiab cov lag luam.
• Lub luag haujlwm tseem ceeb ntawm qhov no yog txhawm rau txo qhov hluav taws xob los muab kev sib cais ntawm ob lub windings ua thawj thiab theem nrab.
• Lub tshuab hluav taws xob no faib hluav taws xob rau thaj chaw deb uas tsim los ntawm cov chaw tsim hluav taws xob.
• Feem ntau, qhov transformer no faib hluav taws xob hluav taws xob rau kev lag luam nrog tsawg dua 33KV voltage thiab 440V rau 220V rau cov hom phiaj hauv tsev.
3. Qhov sib txawv ntawm lub hwj chim transformers thiab tis transformers
a. Muaj nuj nqi siv
Fais fab transformerssiv nyob rau hauv kev sib txuas lus muaj ib tug ntau dua voltage rau ntaiv thiab cov kauj ruam daim ntawv thov (400 kV, 200 kV, 110 kV, 66 kV, 33kV) thiab feem ntau rated saum 200MVA.
Fais fab mov transformeryog siv rau qis voltage faib network los txuas cov neeg siv kawg. (11kV, 6.6 kV, 3.3 kV, 440V, 230V) thiab feem ntau ntsuas qis dua 200 MVA.
b. Transformer loj thiab qib rwb thaiv tsev
Lub zog transformeryog siv rau kis tau tus mob ntawm hnyav loads, ib tug high voltage ntau dua 33kV & 100% efficiency. Nws kuj yog qhov loj dua qhov kev faib tawm transformers; nws yog siv nyob rau hauv lub zog tsim chaw nres tsheb thiab kis tau tus mob substations-siab rwb thaiv tsev theem.
Fais fab transformersyog siv los faib hluav taws xob hluav taws xob ntawm qhov hluav taws xob qis qis dua 33KV rau kev lag luam thiab 440v-220v rau cov tsev nyob.
Nws ua haujlwm nrog kev ua haujlwm qis ntawm 50-70%, yog qhov me me, yooj yim rau nruab, muaj qhov sib nqus tsis tshua muaj zog thiab nws tsis tas yuav thauj khoom tas li.
c. Kev ua haujlwm siab tshaj plaws
Qhov sib txawv tseem ceeb ntawm kev faib khoom siv hluav taws xob thiab qhov chaw yog qhov hloov pauv hloov pauv tau tsim los ua kom tau txais txiaj ntsig siab tshaj plaws ntawm 60% mus rau 70% load vim tias nws ib txwm tsis ua haujlwm tas li. Nws payload nyob ntawm qhov kev thov rau kev faib khoom. Whereas lub transformer yog tsim los ua kom tau qhov siab tshaj plaws ntawm 100% load raws li nws ib txwm khiav ntawm 100% load ze ntawm qhov chaw nres tsheb.
Fais fab transformers yog siv nyob rau hauv faib theem uas voltages yuav qis dua. Qhov thib ob voltage yog yuav luag txhua qhov hluav taws xob muab rau cov neeg siv khoom kawg. Vim muaj kev txwv tsis pub muaj hluav taws xob poob, nws feem ntau tsis tuaj yeem muab qhov hluav taws xob thib ob dhau qhov kev ncua deb.
Yog li ntawd, feem ntau cov tshuab faib khoom feem ntau yuav koom nrog ntau 'pawg' ntawm cov khoom noj los ntawm cov khoom siv hluav taws xob, thiab qhov no txhais tau hais tias qhov kev faib hluav taws xob hloov hluav taws xob tsis tas yuav tsum siab dhau los txhawb nqa cov khoom uas lawv yuav tsum tau ua.
