Hauv kev lag luam fais fab, switchyards thiabsubstationsyog cov khoom tseem ceeb ntawm kev faib khoom, ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob thiab kev xa tawm. Txawm li cas los xij, lawv txawv heev hauv kev tsim, kev ua haujlwm, qhov loj me, thiab cov khoom siv teeb tsa. Kev nkag siab txog qhov sib txawv no pab peb nkag siab zoo txog kev ua haujlwm thiab kev saib xyuas lub zog.
1. Tsim lub hom phiaj thiab ua haujlwm
Lub hom phiaj tsim qauv tseem ceeb ntawm switchyards yog txhawm rau txhim kho lub zog xa hluav taws xob, tshwj xeeb tshaj yog ntawm cov kab hluav taws xob sib txawv hauv tib chav kawm voltage. Nws feem ntau ua haujlwm raws li cov node hauv lub zog hluav taws xob, txuas ob lossis ntau dua cov kab sib kis lossis cov kab hluav taws xob. Qhov no ua rau kev teeb tsa daim phiaj hloov tau yooj yim dua, ua kom muaj kev sib txuas hauv lub network, sib npaug ntawm cov khoom xa tawm, thiab cais thaj chaw tshwj xeeb rau kev saib xyuas. Switchyards yog tshwj xeeb tshaj yog nrov nyob rau hauv cov cheeb tsam uas muaj tsawg qhov chaw, xws li cov nroog, raws li lawv feem ntau tsis xav tau cov av loj. Nws yog ib qho tsim nyog sau cia tias qhov chaw nres tsheb hloov tsis tas yuav suav nrog lub tshuab hloov pauv, yog li nws txoj haujlwm tseem ceeb tsis yog hloov hluav taws xob tab sis yuav tsum tau nruab nrog cov keyboards, Circuit Court breakers, thiab cov cuab yeej tiv thaiv, xws li kev sib cais cov keyboards, Circuit Court breakers, thiab fuses. tswj thiab tiv thaiv kab hluav taws xob.
Hais txog kev hais lus, tus tsim ntawm lub substation yog ntau dua thiab muaj kev ua haujlwm ntau dua. Nws suav nrog cov khoom siv xws li transformers, keyboards, thiab Circuit Court breakers, uas tsis yog siv rau kev hloov hluav taws xob nkaus xwb tab sis kuj rau kev tswj thiab kev tiv thaiv ntawm daim phiaj hluav taws xob. Substations tuaj yeem nce qhov voltage raws li qhov xav tau los ua kom haum rau kev sib kis mus ntev, lossis qis dua qhov hluav taws xob faib hluav taws xob rau cov neeg siv. Cov khoom siv tseem ceeb ntawm asubstationyog lub transformer, thiab nws qhov voltage conversion muaj nuj nqi yog ib qho ntawm qhov sib txawv tseem ceeb ntawm ib tug substation thiab ib tug hloov chaw nres tsheb.
2. Nplai thiab khoom siv
Switchyards yog qhov me me vim tias lawv tsuas yog siv rau kev sib txuas thiab kev tswj hwm ntawm cov kab sib txuas yam tsis tas yuav tsum tau nruab nrog ntau tus transformers lossis lwm yam khoom siv. Qhov kev tsim qauv compact no ua rau qhov chaw nres tsheb hloov tshwj xeeb yog tsim nyog nyob rau hauv ib puag ncig uas qhov chaw txwv.
Nyob rau hauv sib piv, substations yog ntau dua. Qhov luaj li cas ntawm lub substation nws txawv raws li nws cov kev pab cuam cheeb tsam thiab voltage theem, xws li los ntawm me me chaw faib substations mus rau lub regional kis loj substations. Substations feem ntau xav tau qhov chaw loj dua vim qhov xav tau kom haum rau ntau yam khoom siv xws li transformers, switchgear, busbars, thiab lwm yam. Cov khoom siv no ua haujlwm ua ke kom tau raws li qhov xav tau ntawm kev hloov hluav taws xob, kev faib hluav taws xob, thiab kev tiv thaiv kab ke.
3. Lub luag haujlwm hauv daim phiaj hluav taws xob
Nyob rau hauv lub hwj chim network, hloov chaw nres tsheb thiab substations txhua tus muaj lawv tus kheej lub luag hauj lwm nyob rau hauv lub hwj chim system. Switchyards tso cai rau cov tswv lag luam los tswj cov dej ntws tam sim no thiab cais cov kev ua yuam kev yam tsis muaj kev cuam tshuam tag nrho lub cev. Qhov kev muaj peev xwm no yog qhov tseem ceeb hauv kev tswj xyuas kev ruaj ntseg thiab kev ntseeg tau ntawm daim phiaj. Hloov chaw nres tsheb ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ua haujlwm tsis tu ncua ntawm cov tshuab hluav taws xob los ntawm kev hloov kho cov kev sib txuas, ntsuas cov khoom thauj, thiab cais thaj chaw txhaum cai.
Substations ua lub luag haujlwm tseem ceeb hauv kev sib kis tau zoo thiab kev faib hluav taws xob. Lawv xyuas kom meej tias hluav taws xob hloov mus rau qhov tsim nyog voltage rau kev sib kis mus ntev thiab kev nyab xeeb xa mus rau cov neeg siv kawg. Qhov kev hloov pauv voltage no yog lub luag haujlwm tshwj xeeb thiab tseem ceeb ntawm asubstationthiab yog ib qho ntawm qhov sib txawv ntawm qhov chaw nres tsheb hloov.
Feem ntau, txawm hais tias switchyards thiab substations yog ob qho tib si tseem ceeb ntawm lub zog hluav taws xob, lawv muaj qhov sib txawv tseem ceeb ntawm kev tsim lub hom phiaj, kev ua haujlwm, nplai, thiab lub luag haujlwm hauv daim phiaj hluav taws xob. Kev nkag siab txog qhov sib txawv no pab peb nkag siab zoo dua thiab tswj xyuas kev ua haujlwm ruaj khov ntawm cov tshuab hluav taws xob.
Yog xav paub ntxiv txog switchyards thiab substations, thov koj xav mustiv tauj pebthiab peb yuav zoo siab los pab koj.
