Substation: Dab tsi yog substation suav nrog?
Lub transformer yog cov khoom siv tseem ceeb ntawm lub substation. Nws muaj ob windings los ntawm transformers, peb-winding transformers, thiab tsis siv neeg tswj transformers (uas yog, lub high-voltage thiab low-voltage systems qhia ib tug ncaj loj winding, thiab lub taub hau tuam txhab uas muag tuaj yeem kos los ntawm nruab nrab ntawm high-voltage. voltage winding. Outgoing transformer rau tsawg voltage winding). Qhov voltage yog proportional rau winding muaj pes tsawg leeg, thiab tam sim no yog inversely proportional rau winding muaj pes tsawg leeg.
Transformers tuaj yeem muab faib ua cov kauj ruam-up transformers, kauj ruam-down transformers thiab transformers raws li lawv txoj haujlwm. Lub qub yog siv nyob rau hauv lub kis tau tus mob sab substation ntawm lub hwj chim system, thiab tom kawg yog siv nyob rau hauv lub txais sab substation.
Raws li kev sib koom ua ke hloov txoj kev, lub transformer muaj ib tug load-nqa thiab tsis-loaded voltage regulating transformer thiab ib tug tsis-loaded regulating transformer.
Kev ua haujlwm ntawm voltage transformer thiab tam sim no transformer zoo ib yam li cov transformer. Hauv kev ua haujlwm ntsuas, qhov hluav taws xob theem nrab ntawm qhov hluav taws xob hloov hluav taws xob yog 100V, thiab qhov thib ob ntawm qhov tam sim no transformer yog 1A. Qhov thib ob winding ntawm tam sim no transformer feem ntau nyob ze rau luv luv-circuit nrog lub load. Tau' tsis qhib txoj kev. Txwv tsis pub, qhov hluav taws xob siab yuav ua rau muaj kev puas tsuaj rau cov khoom siv thiab kev nyab xeeb ntawm tus kheej, los yog hlawv lub transformer tam sim no.
Cov khoom siv hluav taws xob hloov hluav taws xob muaj xws li cov hluav taws xob hluav taws xob, cov hluav taws xob sib cais, cov khoom siv hluav taws xob, cov hluav taws xob siab, thiab lwm yam. Cov hluav taws xob hluav taws xob yog siv los kaw thiab txiav tawm Circuit Court thaum lub zog hluav taws xob ua haujlwm ib txwm muaj. Thaum muaj kev txhaum tshwm sim, nyob rau hauv kev tswj hwm ntawm cov khoom siv tiv thaiv relay, cov cuab yeej ua txhaum thiab Circuit Court tuaj yeem raug txiav tawm, thiab tuaj yeem siv rov ua haujlwm tsis siv neeg.
Lub luag haujlwm tseem ceeb ntawm kev sib cais tswj kev hloov pauv (riam hloov) yog cais tawm qhov ua haujlwm voltage thaum cov khoom siv lossis cov khoom siv hluav taws xob tswj xyuas kom ntseeg tau cov ntaub ntawv kev ruaj ntseg. Lub load tam sim no thiab luv-circuit tam sim no tsis tuaj yeem sib cais, yog li nws yuav tsum tau siv nrog lub tshuab hluav taws xob. Thaum lub hwj chim tsis ua hauj lwm, rub lub Circuit Court breaker ua ntej, ces rub lub rho tawm mus. Thaum muab hluav taws xob, qhov hloov pauv yuav tsum tau muab tso ua ntej, thiab tom qab ntawd lub Circuit Court breaker yuav tsum raug kaw. Kev ua haujlwm tsis raug yuav ua rau cov khoom puas thiab raug mob ntawm tus kheej.
Kev hloov pauv ntawm lub substation tuaj yeem cais cov load tam sim no thaum lub sijhawm ua haujlwm ib txwm muaj, thiab tsis muaj peev xwm cais qhov txhaum tam sim no. Nws feem ntau yog siv nrog lub siab-voltage fuse rau qhov hluav taws xob siab tshaj 10kV, thiab yog siv rau lub tshuab hluav taws xob lossis cov khoom siv uas tsis ua haujlwm ntau zaus.
Txhawm rau txo qhov chaw nyob ntawm lub substation, sulfur hexafluoride tag nrho cov khoom sib txuas (GIS) tau siv dav. Kev sib xyaw ua ke ntawm Circuit Court breaker, cais hloov, tsheb npav, hloov chaw hauv av, thiab transformer yog qhov me me, tsis cuam tshuam los ntawm huab cua, thiab muaj kev tu ncua ntev. Nrog rau qhov zoo ntawm kev sib tsoo hluav taws xob thiab hluav taws xob cuam tshuam, 765KV tau muab tso rau hauv kev siv hauv substation ua ntej tsim hluav taws xob.
