Lub substation txuas, raws li lub npe implies, yog qhov txuas uas hloov qhov hluav taws xob, uas yog ua tiav hauv substations thiab substations. Transformers thiab tis transformers nyob rau hauv lub fais fab nroj tsuag kuj yog "fais fab transformation", tab sis thaum peb tham txog lub hwj chim daim phiaj txuas, lub hwj chim transformation yog tshwj xeeb tshaj yog lub substation ntawm lub hwj chim grid tuam txhab, uas yog, ib tug loj substation saum toj no 10kV (tsis suav nrog).
Basic qhia txog substation
#Q1 Vim li cas hloov hluav taws xob?
Rau kev xa hluav taws xob mus ntev, qhov siab dua qhov hluav taws xob, qhov me me tam sim no thiab qhov poob me me, yog li kev hloov pauv hluav taws xob feem ntau yog los txo qhov poob. Thiab yog tias nws nyob ze rau thaj chaw nyob, qhov hluav taws xob yuav qis dua thiab kev nyab xeeb yuav raug txhim kho.
#Q2 Txoj Cai ntawmzog transformation(voltage transformation)
Lub hauv paus ntsiab lus ntawm kev hloov hluav taws xob hloov pauv yog hloov AC voltage los ntawm kev hloov cov lej ntawm ob lub coils ntawm transformer, uas tuaj yeem nce lossis txo qhov voltage.
Lub zog hluav taws xob los ntawm lub tshuab hluav taws xob yog txhawb nqa los ntawm substation rau kev sib kis mus ntev. Thaum nws ncav cuag tus neeg siv lub zeem muag, qhov voltage yog txo raws li qhov xav tau thiab faib rau tus neeg siv.
Basic qauv ntawm lub hwj chim system
Lub substation tsuas yog nce lossis nqis ntawm qhov hluav taws xob hluav taws xob los pab txhawb kev sib kis thiab siv hluav taws xob. Nws kuj sau ntau qhov chaw siv hluav taws xob thiab faib rau cov neeg siv los txhim kho kev ntseeg tau ntawm lub zog.
Lub substation nyob rau hauv lub hwj chim transformation txuas npog ib tug loj cheeb tsam thiab muaj ib tug high voltage theem.
substation
Cov hluav taws xob tso tawm los ntawm lub tshuab hluav taws xob tuaj yeem txhawb nqa mus rau 500kV, 330kV, lossis 220kV los ntawm substation. Tom qab ncav cuag ib qho kev ncua deb, qhov voltage yog txo los ntawm lub substation ntawm 500 mus rau 330 mus rau 220 mus rau 110 mus rau 35 mus rau 10 (unit yog kV).
Tab sis 10kV tseem yog siab dhau piv rau qhov hluav taws xob siv hluav taws xob niaj hnub. Cov transformers peb tuaj yeem pom nyob ib sab ntawm peb cov zej zog hloov 10kV lossis 6kV hluav taws xob rau hauv 380V rau lub Hoobkas hluav taws xob lossis 220V rau hluav taws xob hauv tsev.
