Lub Sijhawm Saib Xyuas

Muaj cov kev cai tswj xyuas txog lub sijhawm tu, tab sis lawv tuaj yeem hloov kho raws li qhov xwm txheej tam sim no thiab cov khoom siv. Muaj peev xwm hloov kho rau lub sijhawm ntawm kev saib xyuas kev ua ub no yog ua los ntawm tus thawj engineer ntawm lub chaw. Hais txog qhov yooj yimCov kev cai rau qhov zaus ntawm kev saib xyuas ntawm transformer substations, lawv teem caij raws li nram no:

  • Tsev teem caij xeem - ib xyoos ib zaug.
  • Kev tshuaj xyuas tshwj xeeb tom qab muaj kev puas tsuaj - tam sim tom qab kho lossis hnub tom qab.
  • Kev tshuaj xyuas txawv txav tom qab qhov tsis ua tiav ntawm cov khoom tseem ceeb - tam sim tom qab lub cuab yeej kho lossis hnub tom qab.
  • Kev tshuaj xyuas lub caij nyoog - ua ntej thiab tom qab lub caij cua sov.
  • Kev kuaj xyuas hauv av - txhua zaus kev kuaj xyuas kev ncaj ncees ntawm cov ntsiab lus ntawm lub substation.
  • Kev ntsuas kev ua haujlwm hauv network - ob zaug hauv ib xyoos.
  • Kev hloov pauv loj - ib zaug txhua 6 xyoo.
  • Tshuaj xyuas qhov xwm txheej ntawm cov rwb thaiv tsev - ib zaug txhua 3 xyoos.
  • Kev tshuaj xyuas cov cuab yeej tiv thaiv - ib zaug txhua 3 xyoos.
  • Kev ua haujlwm ntawm tus kheej (kev tu, zawm, lubrication, thiab lwm yam) - raws li xav tau.

Pab pawg nkag rau kev saib xyuas haujlwm

Txheeb xyuas qhov transformer substation
Txheeb xyuas qhov transformer substation

Raws li cov cai rau kev ua haujlwm ntawm kev teeb tsa hluav taws xob, muaj tsib pawg tsim nyog raws li qib kev nyab xeeb hluav taws xob. Thaum ua haujlwm, cov neeg ua haujlwm pabcuam raug xaiv raws li lawv qhov kev cob qhia thiab kev txawj ntse. Kev tshuaj xyuas ib leeg ntawm cov chaw nres tsheb tuaj yeem ua tau los ntawm cov neeg ua haujlwm nrog pab pawg kam rau tsawg kawg 3. Tsuas yog cov neeg ua haujlwm hluav taws xob muaj qhov tsim nyog. Ntxiv nrog rau kev tshuaj xyuas, cov neeg ua haujlwm ntawm pawg no tuaj yeem txuas thiab txiav cov khoom siv los ntawm lub network nrogVoltage ntawm txog 1000 V.

Raws li kev txhim kho muaj zog ua haujlwm nrog cov chaw nres tsheb ntawm cov kab uas muaj qhov hluav taws xob ntau dua 1000 V, lawv tuaj yeem muab kev pabcuam los ntawm cov neeg ua haujlwm ntawm cov thawj coj thiab cov neeg ua haujlwm ntawm 4th hluav taws xob kev nyab xeeb clearance pab pawg, tab sis tsuas yog ua ib feem ntawm pab pawg. Cov neeg ua haujlwm raug tso cai los tshuaj xyuas cov chaw ua haujlwm substation tsuas yog raws li sau ntawv xaj los ntawm kev tswj hwm.

Cov xwm txheej thiab ua haujlwm xaj

Kev kho yog ua raws li kev txiav txim rau daim ntawv tso cai ua haujlwm raws li daim ntawv teev npe ua haujlwm hauv cov txheej txheem ua haujlwm tam sim no. Ua ntej ua ntau yam haujlwm ntawm ib lub chaw, cov neeg ua haujlwm xaj yuav tsum ua ntej sib koom ua haujlwm ntawm cov neeg ua haujlwm. Thaum muab kev pabcuam rau lub tshuab hluav taws xob hloov hluav taws xob hauv lub network nrog qhov hluav taws xob txog li 1000 V, cov xwm txheej hauv qab no yuav tsum tau ua tiav:

  • Thaj chaw ua haujlwm raug thaiv, thiab cov khoom siv tam sim no raug cais kom deb li deb tau.
  • Cov kws hluav taws xob ua haujlwm ua haujlwm ntawm lub tshuab hluav taws xob, hauv galoshes ua los ntawm cov khoom siv hluav taws xob lossis cov roj hmab txheej.
  • Siv lub cuab tam yam tsis muaj rwb thaiv tsev nkaus xwb nrog cov hnab looj tes dielectric.
  • Kev ua haujlwm hauv khaub ncaws nrog dov lossis lub tes tsho luv tsis tso cai.
  • Thaum ua haujlwm, tsis suav nrog cov haujlwm uas nyob tom qab tus kws kho mob.

Kev tshuaj xyuas ntawm lub tshuab hluav taws xob substation

Kev kuaj pom pom muaj kev kuaj xyuas qhov xwm txheej ntawm lub log tshebhigh-voltage bushings nyob ze cov neeg ntes thiab cov plooj (porcelain insulators). Tus tswv yuav tsum txiav txim siab qhov tsis tuaj los yog muaj cov chips, tawg thiab av ntawm lub fuses ntawm lub transformer substation. Cov kev cai rau kev soj ntsuam hauv kev ua haujlwm ntawm kev teeb tsa kev khiav hauj lwm kuj tau sau cov kev ntsuas ntawm cov ntsuas kub, cov ntsiab lus membrane ntawm cov kav dej, txoj hauj lwm ntawm qhov tsis siv neeg li qub thiab ntsuas silica gel. Cov roj qib tseem raug kuaj xyuas thiab, yog tias ua tau, qhov kev siv ntawm nws qhov kev siv yog kwv yees siv cov cuab yeej ntsuas.

Kev saib xyuas hauv online

Raws li cov txiaj ntsig ntawm kev kuaj pom thawj zaug ntawm lub chaw hloov pauv hloov pauv, kev txiav txim siab tuaj yeem ua rau kev ua haujlwm (tsis tau teem sijhawm) saib xyuas cov khoom siv. Pab pawg ua haujlwm txawb nrog cov ntawv tso cai tsim nyog tau tso cai ua haujlwm li no. Kev pabcuam tus kheej, tshwj xeeb, tuaj yeem ua tau los ntawm cov neeg ua haujlwm nrog pawg 4th hluav taws xob tiv thaiv kev nyab xeeb, thiab ua ib feem ntawm cov tub rog - nrog rau pawg thib 3.

Transformer Substation Maintenance

kev saib xyuas online feem ntau suav nrog kev teeb tsa lossis hloov hluav taws xob teeb tsa. Piv txwv li, yog tias koj xav tau hloov lub tsev mus rau tag nrho cov voltage thaum ntsaws rau hauv lub network tom qab kho. Nyob rau hauv cov ntaub ntawv no, kev saib xyuas ntawm lub transformer substation yuav muaj nyob rau hauv alternately txuas cov khoom mus rau lub network - nrog ib tug jogging voltage mov thiab idling chav tsev rau ob peb teev.

substation decommissioning

Tom qab kev tshuaj xyuas, kuj tuaj yeem txiav txim siab kom tshem tawm cov khoom siv los ntawmkev ua haujlwm. Xws li kev txiav txim siab yog ua los ntawm lub cev tsis muaj zog lossis hnav ntawm ntau lub ntsiab lus tseem ceeb ntawm kev hloov pauv. Tab sis kev teeb tsa ua haujlwm feem ntau raug sau tseg. Piv txwv li, yog tias kev saib xyuas thiab kev kho ntawm transformer substations yog impractical vim cov nqi nyiaj txiag siab, nrog rau kev siv tsawg xav tau, tab sis sib npaug cov qauv tsim. Ua ntej lub substation yog decommissioned, raws li cov txiaj ntsig ntawm kev kuaj xyuas, cov kws tshaj lij commission kos ib qho kev tsim nyog. Tsis tas li ntawd, raws li cov lus pom zoo ntawm cov chaw tsim khoom, lub koom haum ua haujlwm tuaj yeem pov tseg ntawm lub tsev. Ntxiv mus, rau cov capacitors impregnated nrog trichlorobiphenyl, muaj cov kev cai tshwj xeeb pov tseg.

Kev cog lus ntawm transformer substation

Ib qho ntawm cov haujlwm tseem ceeb tshaj plaws hauv kev saib xyuas kev teeb tsa hluav taws xob yog kev ua haujlwm. Cov txheej txheem kev ntsuas no muab rau kev siv cov commissioning thiab ua tiav tom qab ua tiav cov kev xeem tiav. Cov kws tshaj lij tshawb xyuas cov cuab yeej siv rau kev ua haujlwm raws li qhov siab tshaj plaws ntawm kev thauj khoom hauv ntau hom. Tsis tas li ntawd, tom qab kev pab cuam ntawm transformer substation, grounding thiab xob laim tiv thaiv yog muab. Cov tub ceev xwm txuas nrog lub ntiaj teb txuas nrog rau kev sim kev teeb tsa. Feem ntau, luv luv Circuit Court yog ua rau cov ntaub ntawv hlau ntawm lub transformer los yog nyob ib sab ntawm cov qauv uas txuas nrog rau hauv av.

Kev txhim kho kev ua haujlwm ntawm cov chaw ua haujlwm ntawm cov phiaj xwm hluav taws xob yog kev siv thev naus laus zis thiab ntau yam. Cov peev txheej ntawm cov haujlwm no tuaj yeem suav nrog kev teeb tsa ncaj qha uas yuav tsum muaj kev tsim nyog los ntawm cov neeg ua yeeb yam, thiab cov haujlwm yooj yim tshaj plaws ntawm kev tiv thaiv. Piv txwv li, thawj pab pawg tiv thaiv kev nyab xeeb hluav taws xob tsis tas yuav muaj kev cob qhia tshwj xeeb thiab tso cai rau cov neeg ua haujlwm ua cov txheej txheem pov thawj yooj yim. Feem ntau, ob peb pab pawg tau ua ke rau kev txheeb xyuas cov khoom siv. Nyob rau tib lub sijhawm, ntau yam kev saib xyuas tuaj yeem ua tiav, lub hom phiaj dav dav uas yuav yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau hloov pauv thiab tom qab ntawd tshem tawm lawv.
