Sab hauv KYN Switchgear Line-Up: Nkag, Tawm, Kev Tiv Thaiv thiab Kev Ntsuas, Vaj Huam Sib Luag los ntawm Vaj Huam Sib Luag
Qhib lub qhov rooj ntawm ib medium-voltage switchgear chav thiab thawj qhov koj pom yog rov ua dua. Kab tom qab kab ntawm steel cubicles, txhua qhov sib npaug ntawm qhov dav, txhua tus nrog lub rooj tswj me me nyob rau pem hauv ntej thiab daim duab qhia txog qhov cubicle ua dab tsi. Repetition zoo li tho txawv. Nws tsis yog. Cov kab ntawd yog li cas chav faib khoom nyob twj ywm thaum muaj kev txhaum tshwm sim rau qhov chaw qis qis.
JSGK muab KYN, XGN thiab cov tsev neeg muaj feem cuam tshuam nrog cov khoom siv hlau rau kev txais, faib, tiv thaiv, saib xyuas thiab ntsuas. Kab lus no piav qhia tias txhua txoj haujlwm hauv kab ua tau zoo li cas, lub vaj huam sib luag pem hauv ntej tau teeb tsa li cas, thiab peb xyuas dab tsi ua ntej lub cubicles tawm hauv lub hoobkas.
Vim li cas ib chav xav tau ntau lub cubicles, tsis yog ib qho
Ib qho khoom siv cable tsis xav tau ib kab. Chav faib khoom tiag tiag. Lub zog tuaj txog ntawm ib lossis ntau cov khoom xa tuaj, thaj av ntawm ib qho chaw nres tsheb, thiab tom qab ntawd tawm mus dua los ntawm ob peb lub tshuab xa tawm uas mus rau transformers, lub cev muaj zog tswj chaw lossis lub nplhaib nodes. Txhua txoj haujlwm no tau txais nws tus kheej lub tsev hlau uas muaj hlau thaiv vim tias txhua txoj haujlwm muaj lub luag haujlwm sib txawv thiab qhov chaw tiv thaiv sib txawv.
Cov kab-up yog kos rau ntawm ib kab kab kos ua ntej ib lub cubicle yog welded. Daim duab ntawd npe lub vaj huam sib luag tuaj, ntu tsheb npav, txhua qhov khoom noj tawm, lub vaj huam sib luag tiv thaiv thiab lub ntsuas ntsuas. Nyob rau hauv pem teb khw, txee teeb kos duab kho qhov dav, qhov tob, pem hauv ntej nkag clearance thiab cable nkag txoj hauj lwm kom cov kab haum rau koj chav.
Plaub txoj haujlwm koj yuav ntsib
- Cov khoom xa tuaj (thiab ntu tsheb npav) vaj huam sib luag. Cov no tau txais cov khoom siv los ntawm cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob thiab txuas mus rau lub ntsiab busbar. Lub tsheb npav-section vaj huam sib luag cais lub tsheb npav kom ob sab tuaj yeem khiav ntawm nws tus kheej lossis nyob rau tib lub sijhawm.
- Cov vaj huam sib luag tawm. Cov no nqa lub zog tawm mus rau txhua qhov load. Lub feeder rau lub transformer, feeder rau lub cev muaj zog, feeder rau lub nplhaib tseem ceeb, txhua tus yog lub siab tshaj tawm qhov cubicle nrog nws tus kheej switchgear.
- Kev tiv thaiv vaj huam sib luag. Cov no tuav cov kev tiv thaiv relays uas paub txog overcurrent, lub ntiaj teb txhaum thiab lwm yam kev txawv txav thiab mus rau qhov cuam tshuam cuam tshuam ua ntej kev puas tsuaj. Cov kev teeb tsa relay tau sib phim rau lub feeder, tsis tau theej hla kab.
- Metering panels. Cov no nqa cov ntsuas thiab ntsuas ntsuas siv los nyeem qhov voltage, tam sim no, lub zog thiab lub zog, feem ntau pub rau cov nqi hluav taws xob lossis cov nroj tsuag lub zog.
Ib chav me me tuaj yeem sib koom ua ke qee lub luag haujlwm rau hauv tsawg dua cubicles. Ib qho loj dua duplicates cov khoom tuaj thiab cov chaw caij npav rau kev ruaj ntseg. Daim duab kab ib kab txiav txim siab nws.
Qhov tseeb yog dab tsi nyob rau pem hauv ntej ntawm lub txee
Sawv ntsug rau pem hauv ntej ntawm KYN qhov cub thiab lub vaj huam sib luag pem hauv ntej ua haujlwm, tsis yog kho kom zoo nkauj. Koj yuav pom ib qho kev tiv thaiv relay lossis maub los nrog cov zaub me me thiab cov pob khawm. Koj yuav pom ib qho analog meter lossis digital ntsuas rau voltage thiab tam sim no. Koj yuav pom qhov taw qhia teeb, tswj cov keyboards thiab kev khiav hauj lwm kov rau lub tshuab hloov.
Hauv qab ntawm cov twj paj nruag, daim duab duab qhia txog lub hauv paus Circuit Court hauv me me: qhov twg lub busbar khiav, qhov twg lub breaker zaum, qhov twg cable compartment tawm. Thaum tus neeg teb xov tooj qhib lub cubicle, tus neeg ua yeeb yam qhia rau lawv, ntawm ib nrais muag, txawm hais tias lub feeder kaw los yog tripped, tsis muaj lawv kov dab tsi. Interlocks, shutters thiab earthing switches yog teem kom ib tug compartment qhib tsis tau thaum nws tseem nyob.
Sab hauv, lub cubicle faib rau hauv cov khoom sib cais: lub tshuab hluav taws xob lossis lub tshuab hloov pauv, lub tshuab hluav taws xob, lub tshuab hluav taws xob, lub tshuab hluav taws xob thiab lub tshuab hluav taws xob qis lossis theem nrab rau kev tswj thiab kev tiv thaiv thaiv. Kev cais lawv yog txhob txwm ua. Ib qho txhaum nyob rau hauv ib lub compartment yog muaj los ntawm cov hlau barriers es tsis txhob arcing hla tag nrho cov kab.
Thaum koj taug kev ib kab ua tiav, nrhiav peb yam uas cais cov kab tsim-rau-order los ntawm ib qho generic. Lub qhov rooj kaw yuav tsum nqa cov kaw uas npog cov stubs nyob thaum lub breaker tshem tawm. Txhua lub cubicle yuav tsum muaj qhov pom kev hloov pauv hauv av lossis lub ntiaj teb taw tes rau lub cable compartment ua ntej pib ua haujlwm. Thiab lub qhov rooj thib ob yuav tsum qhib yam tsis tau tso tawm ib qho kev cuam tshuam ntawm high-voltage. Cov no yog cov ntsiab lus uas cia tus kws kho tsheb ua haujlwm rau lub feeder yam xyuam xim xyoo tom qab commissioning.
Circuit Court breakers, busbars thiab lwm yam Circuit Court
Lub hauv paus hloov pauv hauv Circuit Court compartment yog lub Circuit Court breaker (los yog lub load-break hloov ntawm cov cubicles yooj yim) uas tuaj yeem ua, nqa thiab tawg tam sim no, thiab mus rau hauv qhov txhaum tam sim no los ntawm kev tiv thaiv relay. Lub busbar tseem ceeb yog tus neeg xyuas pib uas txuas lub vaj huam sib luag tuaj rau txhua lub vaj huam sib luag tawm; nws qhov kev ntsuam xyuas raug xaiv los nqa tag nrho chav tam sim no nrog cov npoo.
Qhov thib ob Circuit Court yog tswj, signaling thiab xaim ntawm relays, twj paj nruag, pushbuttons thiab lub breaker. Nws khiav nyob rau hauv nws tus kheej compartment thiab yog qhov uas feem ntau export defects nkaum. Zoo huv si, sau cov kab txuas txuas ntxiv tseem ceeb npaum li cov tooj liab, vim hais tias lub relay uas mus rau qhov tsis ncaj ncees lawm feeder yog kim txawm tias lub ntsiab busbar zoo.
Yuav ua li cas kab tiv thaiv chav
Muab cov khoom sib xyaw ua ke thiab zaj dab neeg tiv thaiv yog yooj yim. Ib qho khoom noj tawm tawm tsim ib qho luv luv. Tam sim no nce. Cov kev tiv thaiv relay ntawm tus feeder pom lub overcurrent thiab xa cov teeb liab mus rau nws tus kheej breaker. Lub breaker ntawd qhib, tsuas yog tshem tawm cov khoom noj tsis raug thaum lub tsheb npav tseem nyob. Lub vaj huam sib luag tuaj thiab lwm cov feeders tseem khiav. Yog tias tsis raug muab qhab nia relays thiab kev mob siab rau ib qho khoom noj, ib qho txhaum yuav ua rau tag nrho chav nyob rau hauv qhov tsaus ntuj.
Qhov kev muab qhab nia ntawm kev tiv thaiv, kev pub noj los ntawm feeder, yog txiav txim siab ntawm daim duab kab ib kab thiab kuaj xyuas thaum sib dhos thiab txuas txuas ntxiv.
Kev niaj hnub thiab kev tshuaj xyuas ua ntej xa khoom
Ob lub rooj kuaj xyuas zaum ntawm ib kab tiav thiab lub thawv. Kev tshuaj xyuas niaj hnub ua haujlwm raws li lub cubicles zoo li qub, xyuas qhov tsim tawm tsam cov duab kos. Kev tshuaj xyuas tawm yog qhov kawg dhau los: kev kuaj xyuas qhov ntev, saib cov txheej txheem, kev tshuaj xyuas cov khoom thiab kev kuaj xyuas tias cov kab txuas txuas txuas ntxiv thiab kev sib cuam tshuam coj tus cwj pwm raws li daim duab hais. Cov ntaub ntawv soj ntsuam thiab cov ntaub ntawv xeem tau npaj nrog kev txiav txim, yog li koj pab neeg hauv tsev kawm ntawv thiab koj tus kws tshuaj ntsuam xyuas tus kheej tuaj yeem nyeem qhov tau kuaj xyuas.
Kev teeb tsa zaum kawg raug kaw los ntawm cov ntawv pov thawj pom zoo, cov kab kos ib kab, kos duab kos duab kos duab thiab cov qauv tsim ua ntej tsim khoom. Qhia rau peb cov qib voltage (10kV thiab 35kV chav kawm yog ib yam ntawm cov kab no), qhov ntsuas tam sim no, theem luv-circuit, tus naj npawb ntawm cov hluav taws xob tawm thiab qhov chaw ib puag ncig, thiab peb yuav nteg tawm kab kom haum rau koj chav.
