Transformer xaiv feem ntau yuav tsum tau txiav txim siab los ntawm nam ntawm transformer muaj peev xwm, voltage, tam sim no thiab ib puag ncig tej yam kev mob. Ntawm lawv, kev xaiv lub peev xwm yuav tsum tau ua raws li lub peev xwm, qhov xwm txheej thiab lub sijhawm ntawm kev siv cov neeg siv khoom siv hluav taws xob los txiav txim siab txog qhov yuav tsum tau ua, thiaj li xaiv lub peev xwm ntawm lub transformer. Thaum lub sijhawm ua haujlwm ib txwm muaj, lub zog hluav taws xob hloov pauv yuav tsum yog li 75% mus rau 90% ntawm lub peev xwm ntsuas ntawm lub transformer.

Yog hais tias qhov tseeb rated load ntawm lub transformer yog tsawg tshaj li 50% thaum lub sij hawm ua hauj lwm, lub me me peev xwm transformer yuav tsum tau hloov, thiab yog hais tias nws yog ntau tshaj li lub peev xwm ntawm lub transformer, lub loj transformer yuav tsum tau hloov tam sim ntawd. Nyob rau tib lub sij hawm, thaum xaiv ib tug transformer, thawj winding voltage tus nqi ntawm lub transformer yuav tsum tau txiav txim raws li lub hwj chim mov kab, thiab lub thib ob winding voltage tus nqi yuav tsum tau xaiv raws li cov khoom siv hluav taws xob. los xaiv qhov tsawg-voltage peb-theem plaub-hlau fais fab mov. Nws tuaj yeem muab lub zog thiab lub teeb pom kev zoo tib lub sijhawm.

Thaum peb feem ntau xaiv cov khoom siv hluav taws xob faib khoom, yog tias lub peev xwm loj dhau, qhov tshwm sim ntawm “tus nees loj-tswj trolley” yuav raug tsim, uas tsis yog tsuas yog nce cov cuab yeej siv peev, tab sis kuj tseem ua rau lub tshuab hloov pauv hauv lub xeev tsis muaj kev thauj khoom rau ib qho. ntev. . , nce reactive zog poob; Yog hais tias lub peev xwm ntawm lub transformer me me dhau lawm, lub transformer yuav nyob rau hauv lub overloaded lub sij hawm ntev, thiab lub transformer yuav hlawv tawm yooj yim, txawm nws yog ib tug autotransformer los yog peb-theem transformer, nws yog tib yam. Yog li ntawd, xaiv txoj cai transformer muaj peev xwm yog ib qho ntawm cov kauj ruam tseem ceeb los txo qhov poob thiab txuag lub zog hauv daim phiaj hluav taws xob. Hauv kev siv tswv yim, peb tuaj yeem xaiv lub peev xwm transformer raws li

mus rau txoj kev yooj yim hauv qab no.

Kauj ruam:

1. Thaum peb feem ntau xaiv ib qho kev faib khoom transformer, yog tias lub peev xwm loj dhau, qhov tshwm sim ntawm “tus nees loj-trolley” yuav raug tsim, uas tsis yog tsuas yog nce cov cuab yeej siv peev, tab sis kuj tseem ua rau lub tshuab hloov pauv tsis muaj kev thauj khoom rau ntev. ntev Yog hais tias lub peev xwm ntawm transformer me me dhau lawm, lub transformer yuav nyob rau hauv lub overloaded lub sij hawm ntev, thiab nws yog ib qho yooj yim mus hlawv tawm lub transformer, txawm nws yog ib tug autotransformer los yog peb-theem transformer, nws yog tib yam. Yog li ntawd, xaiv txoj cai transformer muaj peev xwm yog ib qho ntawm cov kauj ruam tseem ceeb los txo qhov poob thiab txuag lub zog hauv daim phiaj hluav taws xob. Hauv kev siv tswv yim, peb tuaj yeem xaiv lub peev xwm transformer raws li cov qauv hauv qab no yooj yim.

2. Lub hauv paus ntsiab lus ntawm “muaj peev xwm me me, ntom ntom” yuav tsum ua raws li. Lub tshuab xa hluav taws xob yuav tsum tau muab tso rau hauv qhov chaw thauj khoom kom ntau li ntau tau, thiab lub hwj huam hluav taws xob yuav tsum tsis pub tshaj 0.5 kilometers. Tus nqi thauj khoom ntawm lub transformer faib yog siab tshaj ntawm 0.5 thiab 0.6, thiab tam sim no lub peev xwm ntawm transformer yog hu ua economic peev. Txawm li cas los xij, yog tias cov khoom thauj tau ruaj khov, lub peev xwm transformer tuaj yeem raug xaiv raws li kev lag luam muaj peev xwm ntawm kev tsim khoom tas mus li.

3. Raws li cov yam ntxwv ntawm cov neeg siv hluav taws xob nyob deb nroog tawg tawg, tsis tshua muaj load ceev, muaj zog raws caij nyoog thiab sib cuam tshuam muaj zog load, thiab lwm yam, muaj peev xwm hloov pauv hloov tau siv tau. Lub peev xwm tswj kev hloov pauv hloov pauv yog lub tshuab hloov pauv uas tuaj yeem kho qhov tsis muaj peev xwm raws li qhov loj ntawm lub thauj khoom, tsim nyog siv rau hauv qhov chaw uas muaj kev hloov pauv raws caij nyoog hauv kev thauj khoom kom pom tseeb. Rau substations los yog kev lag luam thiab mining tuam txhab uas muag nrog lub hwj chim loj loads, lub ntsiab thiab subsidiary transformers feem ntau yog siv rau lub hwj chim mov, ib tug (niam) yog configured raws li qhov siab tshaj plaws load, thiab lwm yam (secondary) yog xaiv raws li qhov tsawg load. , uas tuaj yeem txhim kho kev faib hluav taws xob zoo heev. Transformer siv, txo qhov tsis muaj-load poob ntawm kev faib transformers. Raws li qhov tseeb hais tias qee qhov kev faib tawm transformers nyob rau hauv cov cheeb tsam nyob deb nroog yog nyob rau hauv tsawg-loading lub sij hawm ntev, tshwj tsis yog rau ib tug me me ntawm lub ncov hluav taws xob loads nyob rau hauv ib lub xyoo, rau cov neeg siv nrog tej yam kev mob, leej niam-tus tub transformer los yog transformer parallel kev khiav hauj lwm hwj chim. hom khoom siv kuj tseem siv tau. Thaum lub load hloov pauv zoo heev, raws li lub hauv paus ntsiab lus ntawm qhov poob qis tshaj plaws, muab tso rau hauv lub tshuab hluav taws xob nrog lub peev xwm sib txawv. Rau cov transformers tshwj xeeb uas tsuas yog muab lub zog rau lub hwj chim loads xws li irrigation thiab kua, lub peev xwm transformer feem ntau yuav raug xaiv raws li 1.2 npaug ntawm asynchronous motor nameplate zog. Feem ntau, lub cev muaj zog pib tam sim no yog plaub mus rau xya npaug ntawm qhov ntsuas tam sim no, thiab lub tshuab hloov pauv yuav tsum muaj peev xwm tiv taus qhov cuam tshuam no.Lub peev xwm ntawm ib qho ntawm cov motors loj tshaj plaws pib ncaj qha feem ntau yuav tsum tsis pub tshaj 30% ntawm lub peev xwm transformer. Nws yuav tsum tau taw qhia tias qhov tshwj xeeb transformers rau cov kua dej thiab dej yuav tsum feem ntau tsis txuas nrog rau lwm yam loads, yog li nres lub lag luam nyob rau hauv lub sij hawm thaum lub sij hawm uas tsis yog-kua thiab irrigation lub sij hawm thiab txo cov hluav taws xob poob.
