Qee qhov tseem ceeb ntawm cov kev ntsuas cuam tshuam nrog transformers suav nrog

1. Rated peev: yog hais txog qhov ntsuas tso zis muaj peev xwm ntawm lub tshuab hloov pauv raws li kev ntsuas kev ua haujlwm (sib npaug rau U × I, chav tsev: kVA);

2, rated voltage: tsis muaj load, rated sub, davhlau ya nyob twg voltage tus nqi (piv txwv li thawj thiab theem nrab voltage tus nqi);

3, tsis muaj load poob: nyob rau hauv tsis muaj-load tej yam kev mob, transformer poob (tseem hu ua hlau noj);

4. Tsis muaj-load tam sim no: tus nqi tam sim no los ntawm thawj kauj ruam nyob rau hauv tsis muaj-load mob;

5, luv luv Circuit Court poob: qhov ntsuas tam sim no ntawm thawj sab, qhov poob los ntawm qhov thib ob luv luv Circuit Court (tsuas yog tshwm sim los ntawm cov coil tsis kam);

6, coj mus rhaub (kais) lub tswv yim: txhawm rau ua kom tau raws li qhov xav tau ntawm kev ua haujlwm ntawm lub zog hluav taws xob, lub tshuab hluav taws xob dav dav dav dav muaj cov kais dej, tus nqi hluav taws xob ntawm cov kais dej no tau nthuav tawm los ntawm feem pua ​​​​ntawm cov ntsuas hluav taws xob, qhov thiaj li hu ua kais voltage.

Piv txwv li, 10kV transformer muaj ± 5% coj mus rhaub, uas txhais tau hais tias lub transformer tuaj yeem ua haujlwm ntawm peb theem voltage: 10.5kV(+5%), 10kV(rated), thiab 9.5kV(-5%).

Feem ntau hais lus, tus kais tus naj npawb ntawm on-load voltage regulating transformer (cov ntsiab lus) ntau, xws li 7 ntsiab lus hu (± 3 × 2.5%) thiab 9 ntsiab lus hu (± 4 × 2%).Vim hais tias lub synchronous switching ntawm kais hloov tsis tau. tau lees paub, qhov hluav taws xob ntawm qhov hluav taws xob tswj kev hloov pauv feem ntau tsis tuaj yeem khiav hauv qhov sib npaug.

Active load: lub load nyob rau hauv lub hwj chim system uas generates tshuab lub zog los yog tshav kub zog.Tab sis nyob rau hauv lub load, lub ntshiab resistive load tsuas yog siv lub zog active, xws li hluav taws xob cua sov, hluav taws xob rauv, teeb pom kev zoo thiab lwm yam hluav taws xob load yog kiag li active load.

Lub load ntawm asynchronous lub cev muaj zog thiab synchronous lub cev muaj zog siv ob qho tib si active zog thiab reactive zog, thiab ib feem uas ua hauj lwm los tsim tshuab lub zog belongs rau active load.Lub active load yog nkag los ntawm lub active zog ntawm lub generator.

8. Reactive load: ib feem ntawm ib qho hluav taws xob load uas tsis ua hauj lwm.Reactive zog yog noj xwb nyob rau hauv inductive loads.Xws li: transformer, lub cev muaj zog, cua txias, tub yees thiab lwm yam.Yog li ntawd, thaum lub generator outputs active zog, nws kuj. yuav tsum tau muab lub zog reactive.

Thaum lub zog reactive tsis tuaj yeem ua tau raws li daim phiaj hluav taws xob, qhov hluav taws xob ntawm qhov system yuav poob. Yuav kom ua tau raws li cov kev xav tau ntawm cov neeg siv, reactive compensator yuav tsum tau nruab rau hauv lub substation kom muaj qhov sib npaug ntawm lub zog reactive, thiaj li tswj tau qhov voltage.

9. Thaum muaj xwm txheej ceev: Ib qho ntawm cov khoom muaj peev xwm khaws cia hauv lub zog hluav taws xob. Lub zog hluav taws xob tuaj yeem cuam tshuam los ntawm ib ntus lossis tas mus li tsis ua haujlwm ntawm cov cuab yeej tsim hluav taws xob, yog li lub kaw lus yuav tsum teeb tsa qee qhov xwm txheej ceev standby fais fab mov kom muaj kev nyab xeeb. ntawm cov chaw muaj zog.

10. System disassembly: Ib qho kev ntsuas kom decompose lub zog ua tiav rau hauv ob peb lub tshuab ywj pheej uas tsis ua haujlwm synchronously, txhawm rau tiv thaiv cov txheej txheem tawm ntawm cov kauj ruam thiab kev sib tsoo tshwm sim.Qee lub tshuab hauv zos yuav muaj hluav taws xob tsis txaus, zaus thiab voltage poob tom qab disassembling, yog li ib feem ntawm cov load yuav tsum tau muab tshem tawm kom tsis txhob muaj kev ruaj ntseg ntawm tag nrho cov system los ntawm kev puas tsuaj.
