Ntau lub teb chaws ntsib ib qho kev sib tw: yuav ua li cas txhawm rau txhim kho cov laus substations ntawm tus nqi qis. Cov cuab yeej qub txeeg qub teg los ntawm ABB, Siemens, thiab Cooper-xws li ncej-mounted transformers, ncoo-mounted transformers, thiab siab-voltage disconnect keyboards- yog mus txog qhov kawg ntawm nws cov kev pab cuam lub neej. Kev yuav khoom tshiab yog kim, thiab ib txwm muaj kev txhawj xeeb tias kev hloov pauv yuav tsis haum, ua rau cov nqi hloov pauv uas tuaj yeem tshaj tus nqi khoom siv.
Raws li tus kws tshaj lij kev lag luam ntawm cov roj- puv fais fab transformers, qhuav- hom transformers, thiab cua so disconnect keyboards, peb daws cov teeb meem no txhua hnub. Qhov tseeb yog, xaiv txoj cai substation transformer lossis load break hloov tuaj yeem ua tiav kev hloov kho nrog tus nqi qis thiab ua haujlwm siab. Kev tuav cov blocks uas twb muaj lawm thiab cov xaim sab nraud thaum ntxiv cov thawv sib txuas yog qhov ua pov thawj. Ib qho kev siv hluav taws xob tau siv txoj kev no thiab muaj lawv lub ncoo -mounted switchgear rov qab online hauv lub lis piam, txuag 20% piv rau kev hloov pauv tag nrho. Tib lub hauv paus ntsiab lus siv rau kev faib tawm-chav hloov pauv thiab kev rho tawm cov hloov pauv: tsuav yog qhov txuas txuas ntxiv, lub hauv paus tseem tsis tau kov.
Thaum peb nug cov neeg siv khoom ntsuas, thawj yam uas peb xav tau yog qhov sib txuas qhov sib txuas rau lawv lub zog hloov hluav taws xob uas twb muaj lawm lossis pab pawg - ua haujlwm hloov. Qhov chaw no - mus rau - nruab nrab ntawm qhov kev ncua deb ntawm mounting bolts txiav txim siab seb tus tshiab substation transformer los yog ntsug lov hloov mus rau nruab rau ntawm lub ncoo uas twb muaj lawm los yog yuav tsum tau tawg ua vaj tse. Peb tau pom ntau txoj haujlwm uas qhov kev ntsuas yooj yim no tau saib tsis pom, ua rau muaj txiaj ntsig zoo rau kev ua haujlwm rau qhov yuav tsum tau hloov pauv hloov pauv ncaj qha.
Tom ntej no, peb yuav tsum paub lub davhlau ya nyob twg txoj haujlwm ntawm lub siab tam sim no -voltage switchgear lossis faib transformer. Sab twg yog cov kev sib txuas tuaj? Qhov av siab npaum li cas? Cov duab ua haujlwm zoo tshaj plaws ntawm no-lawv tshem tawm qhov kev kwv yees. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau qhov chaw -so disconnect switches thiab load interrupter keyboards, qhov twg qhov kev sib txuas ntawm lub davhlau ya nyob twg cuam tshuam ncaj qha rau kev ua haujlwm hauv tsheb npav. Ob peb daim duab ntawm cov kab hloov pauv uas twb muaj lawm tuaj yeem txuag cov sij hawm rov qab - thiab - tawm mus nrog pab pawg engineering.
Cov ntaub ntawv thib peb yog tag nrho qhov ntev ntawm cov roj uas twb muaj lawm -filled transformer lossis hlau - kaw hloov. Cov chaw qub qub tsis tshua muaj qhov chaw ntxiv. Lub ncoo tshiab -mounted transformer uas yog rau nti ntev yuav tsis haum los ntawm lub qhov rooj los yog mus rau hauv lub bay. Peb ib txwm pom zoo kom ntsuas qhov ntev, qhov dav, thiab qhov siab ntawm lub substation transformer uas twb muaj lawm, thiab xyuas cov kev nkag mus thaum nyob ntawm qhov chaw. Nws txuag qhov kev poob siab ntawm kev nrhiav pom qhov teeb meem haum thaum xa tawm ntawm qhov hloov pauv hloov tshiab.
Ua ntej muab qhov kev txiav txim, muaj ob peb yam tsim nyog lees paub nrog koj tus neeg xa khoom hloov pauv lossis cov chaw tsim khoom hloov pauv. Ua ntej, txheeb xyuas qhov mounting qhov ntev ntawm lub qub faib transformer qauv tiv thaiv qhov lawv muab. Qhov thib ob, nug rau kev teeb tsa cov duab kos ntawm lawv qhov kev hloov pauv lossis lub zog hloov pauv thiab sib piv nrog koj qhov ntsuas ntsuas. Yog tias txhua yam ua tau zoo, txawm tias tus neeg cog lus yuav them rov qab lub hauv paus rau lub substation transformer tau txais kev cawmdim. Thib peb, yog tias daim ntawv teev npe raug hnav tawm -thiab feem ntau nws nyob ntawm cov khoom siv hnub nyoog no- nug seb lawv puas tuaj yeem ua haujlwm los ntawm koj qhov kev ntsuas lossis lees txais qhov hloov pauv qub rau 拆解 thiab ntsuas. Cov neeg muab khoom lag luam uas nqis peev sijhawm ua ntej kom ntseeg tau tias qhov hloov pauv hloov pauv yog qhov tsim nyog khaws cia rau hauv koj daim ntawv teev npe.
Yog tias tsim nyog hloov pauv tag nrho, qhov tseem ceeb yog seb lub zog tshiab hloov pauv lossis qhov hloov pauv cuam tshuam tuaj yeem txuas rau ntawm lub hauv paus qub. Yog tias ua tau, kev ua haujlwm pej xeem raug zam tag nrho. Unbolt lub qub faulty disconnect hloov thiab nruab qhov tshiab hloov pauv hloov pauv ncaj qha- tsuas yog ntsia liaj qhov rooj rau thiab nws npaj mus. Txoj hauv kev no tau cawm peb cov neeg siv khoom suav tsis suav sijhawm ntawm kev tsim kho lub sijhawm thiab ntau txhiab tus nqi cog lus rau kev hloov kho substation switchgear.
Rau cov roj-immersed fais fab transformers, kev ntsuam xyuas ntawm 200 mus rau 2,500kVA feem ntau yog nyob rau hauv Tshuag. 10kV, 24kV, thiab 35kV peb-theem transformers yog muaj nyob rau hauv mounting qhov ntev sib xws nrog legacy ABB, Siemens, thiab Cooper ncej{8} Losses khiav txog 10% qis dua lub teb chaws tus qauv, uas ntxiv rau cov txiaj ntsig zoo tshaj plaws hauv lub neej ntawm kev faib khoom transformer.
Rau siab -voltage cua disconnect keyboards los ntawm 12kV mus rau 40.5kV, peb tsim pab pawg- ua haujlwm hloov nrog cov neeg sib cuag nyiaj -plated rau 6μm-ob npaug rau lub teb chaws tus qauv ntawm 3μm- nqa txog 30% tam sim no. Lawv yog cov kev hloov pauv ncaj qha rau cov qub qub Cooper, ABB, thiab Siemens ntsug qhov hloov pauv thiab qhov chaw nruab nrab -so disconnects, nrog rau qhov sib npaug ntawm qhov sib nrug thiab ua ntej- cov neeg tiv tauj greased npaj rau kev teeb tsa thaum tuaj txog. Cov kev cuam tshuam sab nraum zoov no yog tsim rau cov ntawv thov kev sib cais substation thiab tuaj nrog cov neeg siv phau ntawv lossis lub cev muaj zog raws li xav tau.
Yog tias koj tsis muaj ib qho kev npaj ua ntej - ua kev daws teeb meem rau koj qhov hloov pauv hloov pauv lossis tshem tawm cov hloov pauv rov qab, tiv tauj peb lub vev xaib pabcuam cov neeg siv khoom. Peb mam li kho cov kev daws teeb meem raws li koj cov kev xav tau tshwj xeeb thiab cov xwm txheej hauv cheeb tsam, txawm tias koj xav tau lub ncoo kev cai -mounted transformer lossis ib qho tshwj xeeb thauj khoom tawg.
