Qhov txawv ntawm substation thiab substation yog dab tsi, thiab dab tsi yog lub luag haujlwm ntawm txhua tus?
Qhov chaw qhov voltage hloov. Txhawm rau xa cov hluav taws xob hluav taws xob los ntawm lub tshuab hluav taws xob mus rau qhov chaw deb, qhov hluav taws xob yuav tsum tau nce mus rau qhov hluav taws xob high-voltage, thiab qhov hluav taws xob yuav tsum tau txo qis raws li qhov xav tau nyob ze ntawm tus neeg siv. Qhov kev ua haujlwm ntawm kev nce thiab txo qhov voltage yog ua los ntawm substation. Cov cuab yeej tseem ceeb ntawm lub substation yog hloov pauv thiab hloov pauv.
Raws li kev ntsuas sib txawv, cov me me hu ua substations. Lub substation loj dua lub substation. Substation: feem ntau yog cov kauj ruam-down substation nrog rau qib voltage qis dua 110KV; substation: suav nrog" nce thiab nqis nqis" substations ntawm ntau theem voltage.
Lub substation yog lub chaw tsim hluav taws xob hauv lub zog hluav taws xob uas hloov hluav taws xob, txais thiab faib hluav taws xob hluav taws xob, tswj cov dej ntws ntawm lub zog, thiab kho qhov voltage. Nws txuas cov kab hluav taws xob ntawm ntau yam voltages los ntawm nws cov transformers. Lub substation yog nyob rau hauv ib qho chaw tshwj xeeb; nws yog cov txheej txheem ntawm AC-DC-AC hloov dua siab tshiab. Zoo li submarine kis tau tus mob cables thiab kis tau tus mob mus ntev. Qee tus txais yuav daim ntawv ntawm high-voltage direct tam sim no kis tau tus mob thiab transformation. DC kis tau tus mob overcomes lub capacitive reactance poob ntawm AC kis tau tus mob. Nws muaj kev txuag hluav taws xob.
Substations feem ntau yog high-voltage substations nrog nruab nrab voltage, los yog high-voltage substations nrog tsawg-theem high-voltage. Substations occupies ib cheeb tsam loj, thiab lawv nyob ntawm ntau qhov chaw raws li qhov sib txawv voltage theem thiab muaj peev xwm, yog li qee cov neeg yuav hu lawv substations.
Los ntawm qhov kev xav ntawm kev lag luam fais fab, lub substation yuav tsum nyob ze rau qhov chaw thauj khoom. Los ntawm kev xav ntawm kev tsim khoom, lub substation yuav tsum tsis txhob cuam tshuam kev tsim khoom thiab kev thauj mus los hauv cov nroj tsuag, thiab kev thauj mus los ntawm nws tus kheej cov cuab yeej yuav tsum yooj yim. Los ntawm kev saib xyuas kev nyab xeeb, cov chaw nres tsheb yuav tsum zam qhov chaw tawg thiab tawg. Lub substation yuav tsum nyob rau sab saud ntawm lub tsev. Hauv kev lag luam, nws tsis yooj yim rau kev teeb tsa hauv qhov chaw uas muaj plua plav thiab fiber ntau yooj yim rau kev tso nyiaj. Substations yuav tsum tsis txhob nyob hauv qhov chaw muaj neeg coob. Kev xaiv ntawm qhov chaw thiab kev tsim kho ntawm substations yuav tsum tau coj mus rau hauv tus account cov kev xav tau ntawm kev tua hluav taws, kev tiv thaiv corrosion, tiv thaiv kev ua qias tuaj, tiv thaiv dej, tiv thaiv los nag, tiv thaiv daus, tiv thaiv av qeeg, thiab tiv thaiv cov tsiaj me los ntawm kev nkag.
Muaj nuj nqi: Lub substation yog ib qho kev hloov khoom siv uas txuas lub zog cog rau cov neeg siv. Vim tias lub tshuab hluav taws xob nyob deb heev ntawm lub nroog thiab lub Hoobkas uas siv hluav taws xob, thiab qhov hluav taws xob tsim los ntawm lub tshuab fais fab tsis siab, qhov tam sim no loj heev. Yog tias qhov tam sim no loj, cov cua kub ntau yuav raug tsim tawm ntawm cov kab sib kis raws li Joule' txoj cai. Cov kab sib kis tau puas lawm, thiab kev hloov pauv tam sim no mus rau hauv tshav kub kuj yog qhov poob. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau nce qhov voltage ntawm lub tshuab hluav taws xob los ntawm lub substation mus rau 500,000 volts, thiab tom qab ntawd xa mus rau cov nroog thiab cov chaw tsim khoom uas peb nyob ntev, thiab tom qab ntawd dhau los ntawm lub substation hauv zos. Qhov hluav taws xob tau txo qis thiab muab tso ua ke rau hauv peb lub zog txhua hnub 220V los ntawm kev faib hluav taws xob thiab lwm yam kev ntsuas.
Substation
Nws yog qhov chaw thiab qhov chaw uas qhov voltage hloov. Nws yog qhov chaw uas qhov voltage thiab tam sim no ntawm hluav taws xob lub zog hloov pauv, concentrated thiab faib nyob rau hauv lub zog hluav taws xob. Txhawm rau kom ntseeg tau tias lub zog hluav taws xob zoo thiab kev nyab xeeb ntawm cov khoom siv, kev hloov hluav taws xob, kev tswj tam sim no, thiab kev tiv thaiv cov kab sib txuas thiab cov khoom siv hluav taws xob tseem ceeb kuj tseem yuav tsum tau muaj nyob rau hauv lub substation. Raws li lub hom phiaj, nws tuaj yeem muab faib ua hluav taws xob substation thiab traction substation (rau hluav taws xob railway thiab tram). Lub ntsiab lus txhais tau teev tseg hauv lub teb chaws tus qauv GB50053-2013"Code for Design of Substations 20kv and below" yog" lub zog AC ntawm 20kv thiab hauv qab no yog hloov los ntawm lub hwj chim transformer los muab lub zog rau cov khoom siv hluav taws xob." .
Muaj nuj nqi: Lub substation yog ib qho chaw uas qhov voltage thiab tam sim no ntawm hluav taws xob lub zog hloov, concentrated thiab faib nyob rau hauv lub zog hluav taws xob system. Txhawm rau kom ntseeg tau tias lub zog hluav taws xob zoo thiab kev nyab xeeb ntawm cov khoom siv, kev hloov hluav taws xob, kev tswj hwm, kev sib kis thiab kev faib cov kab thiab cov khoom siv hluav taws xob tseem ceeb kuj tseem yuav tsum tau muaj nyob rau hauv lub substation. Feem ntau, qhov voltage tsis tshaj ib lossis ob kilovolts. Yog tias nws raug xa mus ncaj qha mus rau qhov ntev, cov kab tam sim no yuav loj heev, uas ua rau lub zog poob ntawm txoj kab loj heev, tsis muaj nqi, thiab cov kab hluav taws xob sib kis tau qis heev. Yog li ntawd, ib tug transformer yuav tsum tau siv los ua kom qhov voltage mus rau kaum tawm txhiab volts los yog txawm pua pua txhiab volts (nyob ntawm seb qhov kev ncua deb thiab lub hwj chim) kom txo tau cov kab tam sim no. Txhawm rau txuas cov kab hluav taws xob sib txawv ntawm qhov sib txawv thiab lub zog rau hauv daim phiaj kom muaj kev nyab xeeb tag nrho, ntau qhov chaw yuav tsum tau ua kom sib luag thiab txuas cov kab sib txawv. Ib yam li ntawd, tom qab high-voltage hluav taws xob xa mus rau qhov chaw, nws yuav tsum tau decompressed thiaj li ua tau raws li cov kev xav tau ntawm cov neeg siv sib txawv. Feem ntau, lub substation tseem ceeb yog hais txog lub hauv paus transformer, thiab muaj cov hloov pauv thib ob hauv qab nws. Tus thawj transformer yog siv los hloov high-voltage tis thiab tsis muaj lub luag hauj lwm rau voltage kis.
