Nyob rau hauv cov txheej txheem ntawm kev sib kis thiab kev faib hluav taws xob, lub zog hloov hluav taws xob yog lub hauv paus ntawm kev hloov hluav taws xob thiab kev sib kis. Nws cov kev ua tau zoo thiab kev ua tau zoo yog cuam tshuam ncaj qha rau kev ntseeg tau thiab kev ua haujlwm zoo ntawm lub zog ua haujlwm. Lub zog hloov hluav taws xob tau siv dav hauv ntau yam xws li kev lag luam, kev ua liaj ua teb, kev thauj mus los, thiab cov zej zog hauv nroog, thiab lawv cov nyiaj poob rau kwv yees li 40 feem pua ntawm kev xa tawm thiab kev faib hluav taws xob poob. Rau cov transformers uas ua haujlwm txhua hnub thiab siv ntau lub zog, txhim kho kev siv hluav taws xob, txo kev siv hluav taws xob, thiab txuag hluav taws xob yog qhov ntsuas uas cov neeg siv tau txhawj xeeb tshaj plaws. Yog li yuav ua li cas thiaj xaiv tau lub zog txuag hluav taws xob transformer?
1. Cov qauv siv hluav taws xob rau hluav taws xob hloov hluav taws xob
Tam sim no, muaj ob lub ntsiab lus tseem ceeb hauv teb chaws rau kev ntsuas hluav taws xob hluav taws xob hluav taws xob hluav taws xob, xws li GB 20052-2013 "Lub Zog Hluav Taws Xob thiab Hluav Taws Xob Hluav Taws Xob ntawm Peb-theem Fais Fais Transformers" thiab GB 24790-2009 "Power Transformer Zog Efficiency Limits thiab Energy Efficiency Qib". Ob qho qauv no tau siv los ua haujlwm ntev, thiab cov kev ua haujlwm tsis tau teev tseg hauv cov qauv no tsis ua raws li cov kev cai tam sim no. Txhawm rau txhawm rau txhawb kev txuag hluav taws xob zoo thiab txo qis ntawm cov hluav taws xob hloov hluav taws xob, tus qauv tshiab yuav tsum muaj GB 20052-2020 "Power Transformer Energy Efficiency Limits thiab Energy Efficiency Grades" tau tshaj tawm rau lub Tsib Hlis 29, 2020, thiab yuav raug tso tawm rau hnub tim Lub Rau Hli 1, 2021. tau ua tiav.
2. Lub npe txoj kev ntawm lub hwj chim transformer
JB/T 3837-2016 "Transformer Product Model Compilation Method" qhia cov cai naming ntawm lub hwj chim transformers, thiab cov lag luam tuaj yeem yeem lub npe fais fab transformers raws li tus qauv no. Feem ntau, cov qauv tshwj xeeb suav nrog cov ntaub ntawv xws li hom qauv, cov khoom siv tseem ceeb, qib voltage, thiab ntsuas lub peev xwm ntawm lub zog hloov hluav taws xob. Feem ntau, lub zog hloov hluav taws xob kuj tseem yuav ntxiv daim ntawv lo "-NX1" (thawj-theem zog efficiency) los yog "-NX2" (thib ob-theem zog efficiency) nyob rau hauv qhov kawg ntawm cov qauv kom paub meej lub zog efficiency theem ntawm cov khoom.
Piv txwv li: roj-immersed fais fab transformer, specifications: high-voltage sab voltage 10kV, rated muaj peev xwm 2000kVA, cov khoom tseem ceeb yog silicon steel ntawv, core qauv yog peb-dimensional qhov txhab qhov txhab, lub zog efficiency theem yog 1. Siv cov nram qab no txoj kev rau npe. tus qauv specification:
SM·RL-2000/10-NX1
3. Cov cim tseem ceeb rau kev yuav khoom fais fab transformers
1. Xaiv lub transformer raws li kev siv ib puag ncig
Nyob rau hauv ib txwm nruab nrab tej yam kev mob, roj-immersed transformers los yog qhuav-hom transformers yuav xaiv tau. Nyob rau hauv lub tsev ntau-storey los yog high-sawv lub tsev loj, tsis-combustible los yog tsis-combustible zog transformers yuav tsum tau xaiv. Kaw lossis kaw lub hwj chim transformers yuav tsum raug xaiv nyob rau hauv qhov chaw uas muaj plua plav los yog corrosive gases cuam tshuam rau kev nyab xeeb ntawm transformers. Cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob tsis muaj hluav taws xob tsis muaj roj thiab tsis muaj roj-immersed tis transformers tuaj yeem ntsia tau rau hauv tib chav. Lub sijhawm no, lub tshuab hluav taws xob xa tawm yuav tsum tau nruab nrog IP2X tiv thaiv casing kom muaj kev nyab xeeb.
2. Xaiv lub transformer raws li lub hwj chim load
Feem ntau, nws raug xaiv raws li lub peev xwm ntawm lub hwj chim transformer pom zoo nyob rau hauv GB / T 17468-2019 "Cov lus qhia rau kev xaiv lub hwj chim Transformers". Cov tshuab ziab khaub ncaws qhuav feem ntau yuav tsum tau xaiv raws li GB / T 1094.12-2013 "Cov Lus Qhia rau Load of Dry-type Fais Fab Transformers" thiab cov xam load. Txiav txim siab nws lub peev xwm.
3. Paub cov chav kawm rwb thaiv tsev
Rwb thaiv tsev qib yog hais txog qib cua sov ntawm cov ntaub ntawv insulating siv hauv cov khoom siv hluav taws xob. Cov ntaub ntawv rwb thaiv tsev tuaj yeem muab faib ua 7 qib raws li lawv cov kev tiv thaiv tshav kub, thiab lawv qhov kub thiab txias txwv kuj txawv. Cov chav kawm rwb thaiv tsev ntawm cov hluav taws xob siv hluav taws xob feem ntau yog nruab nrab ntawm A thiab H, cov chav kawm rwb thaiv tsev ntawm cov roj-immersed transformers feem ntau yog A chav kawm, thiab cov chav kawm rwb thaiv tsev ntawm cov tshuab ziab khaub ncaws qhuav feem ntau yog F chav kawm lossis H chav kawm.
4. Tsis-load poob
Tsis muaj-load poob yog hais txog lub zog siv hluav taws xob siv los ntawm cov kab winding terminals thaum lub ntsuas hluav taws xob nyob ntawm qhov ntsuas zaus siv rau cov terminals ntawm ib qho winding thiab lwm qhov windings qhib. Load poob yog hais txog lub zog siv hluav taws xob siv ntawm qhov ntsuas zaus thiab qhov ntsuas kub thaum cov ntsuas tam sim no ntws los ntawm cov kab terminals ntawm ib qho winding thiab lwm qhov winding yog luv luv.
4. Cov khoom lag luam tseem ceeb thiab cov chaw thov
Raws li qhov nruab nrab insulating, fais fab transformers tuaj yeem muab faib ua roj-immersed transformers, qhuav-hom transformers thiab gas-filled transformers.
Roj-immersed transformers muaj xws li ntxhia roj-impregnated transformers thiab high-flammable-point roj (synthetic roj thiab ntuj ester) impregnated transformers. Mineral roj-immersed transformers yog dav siv nyob rau hauv ntau qhov chaw, tab sis kev tiv thaiv hluav taws thiab kev nyab xeeb ntawm qhov chaw installation yuav tsum tau txiav txim siab tag nrho. High ignition point roj muaj kev ruaj ntseg ntau dua vim nws qhov flash point thiab ignition point siab dua cov ntxhia roj. Yog li ntawd, lub siab ignition point roj-immersed transformers feem ntau siv nyob rau hauv cov chaw uas muaj kev ruaj ntseg siab, los yog qhov chaw uas tsis txaus tiv thaiv hluav taws nyob deb ntawm lub tsev.
Qhuav hom transformers feem ntau muaj epoxy resin cam khwb cia insulated qhuav-hom transformers thiab impregnated insulated qhuav-hom transformers. Lub transformer yuav tsum ua raws li cov kev xav tau ntawm combustion theem teev nyob rau hauv GB / T 1094.11, thiab feem ntau yog siv nyob rau hauv tsev substations ua ke nrog cov tsev los yog underground substations nrog zoo waterproof thiab noo noo-pov thawj.
Gas-filled transformers siv cov roj uas tsis yog-combustible gases xws li sulfur hexafluoride los yog cov roj sib xyaw ua cov rwb thaiv tsev thiab cua txias nruab nrab. Lub cev tseem ceeb muaj cov yam ntxwv ntawm cov khoom tsis tawg thiab tsis muaj hluav taws xob, thiab feem ntau yog siv rau hauv qhov chaw uas muaj kev tiv thaiv hluav taws ntau dua thiab kev nyab xeeb.
