Yuav xaiv hom transformer li cas

Laus electrician engineer qhia koj xaivfais fab mov transformerhom thiab xam transformer muaj peev xwm.

Lub zog hloov hluav taws xob yog cov khoom tseem ceeb hauv lub zog hluav taws xob, nws txoj haujlwm tseem ceeb yog txhawm rau txhim kho cov hluav taws xob tsim nyog, thiab muaj cov hluav taws xob tseem ceeb ntawm kev hloov ntawm cov khoom ntawm cov khoom siv thiab nws txoj kev ntseeg siab thiab kev lag luam. Yog li ntawd, qhov raug thiab tsim nyog xaiv ntawm transformer hom, tus naj npawb thiab lub peev xwm yog ib qho teeb meem loj nyob rau hauv kev tsim ntawm lub ntsiab thaiv.

Thaum xaiv transformer faib, yog tias lub peev xwm loj dhau, nws yuav tsim qhov tshwm sim ntawm "lub tsheb nees loj". Nws tsis tsuas yog nce cov khoom siv peev, tab sis kuj ua rau lub transformer nyob rau hauv lub xeev tsis muaj load rau lub sij hawm ntev, thiaj li hais tias lub reactive zog poob nce.

Yog hais tias lub peev xwm transformer tsawg dhau, nws yuav ua rau lub transformer nyob rau hauv lub xeev overload rau lub sij hawm ntev. Yooj yim rau hlawv transformer. Raws li lub hauv paus ntsiab lus ntawm "muaj peev xwm me me, cov ntsiab lus ntom ntom", qhov hloov pauv hloov pauv yuav tsum nyob hauv qhov chaw thauj khoom kom deb li deb tau, lub zog hluav taws xob lub vojvoog tsis tshaj 0.5 km.

Tus nqi thauj khoom ntawm kev faib khoom transformer yog nruab nrab ntawm {{0}}.5 thiab 0.6, thiab lub peev xwm ntawm transformer yog hu ua economic peev. Yog hais tias lub load yog qhov ruaj khov, lub peev xwm transformer tuaj yeem xaiv raws li kev lag luam muaj peev xwm nyob rau hauv cov ntaub ntawv ntawm kev nruam ntau lawm.

Rau qhov tshwj xeeb transformer uas tsuas yog muab lub zog rau lub zog thauj khoom xws li cov dej ntws thiab dej, lub peev xwm ntawm lub tshuab hloov pauv tuaj yeem xaiv raws li 1.2 npaug ntawm lub npe lub zog ntawm lub tshuab asynchronous.

Feem ntau, qhov pib tam sim no ntawm lub cev muaj zog yog 4 ~ 7 zaug ntawm qhov ntsuas tam sim no. Lub transformer yuav tsum muaj peev xwm tiv tau qhov kev cuam tshuam no. Lub peev xwm ntawm lub tshuab loj tshaj plaws ncaj qha pib yuav tsum tsis pub tshaj li 30 feem pua ​​​​ntawm lub peev xwm ntawm lub transformer.

Nws yuav tsum tau muab sau tseg tias cov kua thiab dej tshwj xeeb transformer yuav tsum tsis txhob txuas nrog rau lwm yam loads, thiaj li yuav tsum tau nres nyob rau hauv lub sij hawm nyob rau hauv lub tsis-kua thiab irrigation lub sij hawm thiab txo qhov poob ntawm lub hwj chim.

Rau cov khoom siv hluav taws xob teeb pom kev zoo, kev ua liaj ua teb thiab cov khoom lag luam sab nrauv thiab lwm yam kev xaiv lub zog transformer muaj peev xwm, peb yuav tsum xav txog lub zog ntawm cov khoom siv hluav taws xob tib lub sijhawm, raws li qhov tseeb tau siab tshaj plaws load 1.25 npaug ntawm lub peev xwm ntawm kev xaiv transformer.

Raws li cov yam ntxwv ntawm cov neeg siv hluav taws xob nyob deb nroog dispersed, me me load ceev, load seasonality thiab muaj zog sib txawv, lub peev xwm kho transformer yuav siv tau. Capacity adjusting transformer yog ib hom kev hloov pauv uas tuaj yeem kho lub peev xwm yam tsis muaj kev thauj khoom raws li qhov loj me. Nws yog tsim rau siv nyob rau hauv qhov chaw uas lub load raws caij hloov yog pom tseeb.

Rau substation lossis loj hluav taws xob thauj khoom ntawm kev lag luam thiab kev lag luam mining, kev siv dav dav ntawm niam thiab menyuam transformer fais fab mov, ib qho (niam transformer) raws li qhov siab tshaj plaws load configuration, lwm yam (sub-transformer) raws li qhov tsawg load xeev xaiv, tuaj yeem txhim kho qhov kev faib tawm transformer siv tus nqi, txo qhov kev faib tawm transformer tsis-load poob.

Raws li qhov tseeb qhov xwm txheej uas qee qhov kev faib khoom hloov pauv nyob rau hauv cov cheeb tsam nyob deb nroog nyob rau hauv lub xeev tsis tshua muaj kev ua haujlwm rau lub sijhawm ntev ntxiv rau qhov me me ntawm cov hluav taws xob siab tshaj plaws hauv ib xyoos, cov khoom siv fais fab ntawm niam-me nyuam transformer lossis transformer parallel. kev ua haujlwm kuj tseem tuaj yeem siv rau cov neeg siv kev cai. Thaum lub load hloov pauv zoo heev, raws li lub hauv paus ntsiab lus ntawm qhov poob qis tshaj plaws, lub transformer nrog lub peev xwm sib txawv tau nqis peev.

Lub peev xwm ntawm lub transformer yog ib chav tsev ntawm lub hwj chim (pom meej lub zog), qhia raws li AV (volt ampere) los yog KVA (kilovolt ampere).

Nws yog cov khoom ntawm tus nqi zoo ntawm AC voltage thiab tam sim no, suav nrog cov qauv S=UI. Lub peev xwm ntsuas ntawm lub transformer yuav qhia rau ntawm nws lub npe.

Kev xaiv ntawm transformer yuav tsum paub meej txog kev siv lub peev xwm ntawm lub transformer, uas feem ntau yog xam raws li qhov tseeb load loj ntawm lub hwj chim system.

Ib lub zog siv hluav taws xob, tom qab suav, raws li kev suav load S los xaiv lub peev xwm ntawm lub transformer. Rau ib qho kev hloov pauv nrog hluav taws xob ib ntus (ntawm qhov chaw tsim kho) thiab ruaj khov load fais fab mov, tus nqi thauj khoom feem ntau yog kwv yees li 85 feem pua.
