Tsis-load poob yog hais txog lub zog absorbed los ntawm lubtransformerThaum lub thib ob sab ntawm lub transformer yog qhib-circuited thiab sine yoj voltage ntawm thawj sab yog sib npaug zos rau qhov ntsuas voltage. Feem ntau, tsuas yog qhov ntsuas zaus thiab ntsuas qhov ntsuas hluav taws xob tau them nyiaj rau, thiab qee zaum tsis muaj kev saib xyuas rau tus kais voltage thiab voltage waveform, qhov tseeb ntawm qhov ntsuas ntsuas, ntsuas ntsuas thiab cov khoom siv ntsuas. Muaj kev tsis meej pem dua txog tus nqi suav, tus qauv tus nqi, ntsuas tus nqi thiab lav tus nqi poob.
Yog tias qhov hluav taws xob tau siv rau thawj sab thiab muaj tus kais dej, yog tias lub tshuab hloov pauv tsis tu ncua flux voltage kev tswj, qhov kev siv hluav taws xob yuav tsum yog tus kais hluav taws xob ntawm qhov chaw kais dej sib raug rau cov khoom siv hluav taws xob. Nyob rau hauv cov ntaub ntawv ntawm qhov sib txawv flux voltage regulation, txij li thaum tsis muaj-load poob ntawm txhua kais txoj hauj lwm yog txawv, txoj hauj lwm kais yuav tsum raug xaiv raws li cov kev xav tau thiab cov kev ntsuas voltage yuav tsum tau siv, vim hais tias thaum lub sij hawm sib txawv flux voltage regulation, Thawj sab ib txwm siv qhov hluav taws xob rau txhua txoj haujlwm kais.
Nws yog feem ntau yuav tsum tau hais tias lub waveform ntawm qhov thov voltage yuav tsum yog kwv yees li ib tug sinusoidal waveform. Yog li ntawd, ib tug yog siv ib tug harmonic analyzer los ntsuas cov harmonic Cheebtsam uas muaj nyob rau hauv lub voltage waveform, thiab lwm yam yog siv ib tug yooj yim txoj kev, siv ib tug nruab nrab voltmeter, tab sis nrog ib tug voltmeter scaled rau tus nqi zoo, ntsuas qhov voltage, thiab muab piv nrog tus nqi zoo voltmeter nyeem ntawv. , thaum qhov sib txawv ntawm ob qhov ntau dua 3%, nws txhais tau hais tias qhov hluav taws xob waveform tsis yog sine yoj, thiab qhov ntsuas tsis muaj qhov poob yuav tsum tsis raug raws li qhov yuav tsum tau ua ntawm tus qauv tshiab.
Rau qhov ntsuas ntsuas, nws yog ib qho tsim nyog yuav tsum xaiv cov kab xeem uas tsim nyog, cov cuab yeej ntsuas thiab cov cuab yeej siv. Vim yog kev txhim kho ntawm cov khoom siv hlau nplaum, cov wattage poob ib kilogram tau txo qis heev. Cov neeg tsim khoom tau xaiv cov khoom zoo, cov khoom siv zoo tshaj plaws ntawm cov khoom siv silicon steel los yog txawm tias amorphous alloys ua cov khoom siv hlau nplaum. Hais txog cov qauv, lawv tau tsim cov thev naus laus zis tshiab xws li kev sib txuas ntawm cov ntaiv. Cov seams thiab tag nrho bevels tsis yog ntxeem tau, thiab cov cuab yeej ntawm cov hlau tsis-stacked yoke yog saws. Cov neeg tsim khoom tab tom tsim cov tshuab hluav taws xob qis qis, tshwj xeeb tshaj yog tsis muaj kev poob qis tau txo qis heev. Yog li ntawd, cov kev cai tshiab tau muab tso rau pem hauv ntej rau kev ntsuas qhov system. Lub peev xwm tseem tsis hloov pauv thiab tsis muaj qhov poob qis, uas txhais tau hais tias lub zog ntawm lub tshuab hluav taws xob txo qis thaum nws tsis muaj load. Lub zog me me xav kom cov neeg tsim khoom hloov pauv thiab hloov qhov ntsuas ntsuas. Nws raug nquahu kom siv txoj kev ntsuas peb-wattmeter rau kev ntsuas, xaiv 0.{{10}}}.1 theem transformer, thiab xaiv lub wattmeter nrog lub zog qis. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ntsuas qhov tseeb tau lav. Thaum lub hwj chim yog 0.01, theem sib txawv ntawm lub transformer yog 1 feeb, uas yuav ua rau lub hwj chim yuam kev ntawm 2.9%.
Yog li ntawd, nyob rau hauv qhov tseeb ntsuas, qhov tam sim no piv thiab voltage piv ntawm tam sim no transformer thiab voltage transformer yuav tsum raug xaiv kom raug. Thaum qhov tseeb tam sim no me dua li qhov tam sim no txuas nrog tam sim no transformer, theem sib txawv thiab qhov yuam kev tam sim no ntawm transformer tam sim no yuav loj dua, uas yuav ua rau muaj qhov yuam kev loj dua hauv qhov ntsuas qhov tseeb. Yog li ntawd, tam sim no kos los ntawm lub transformer yuav tsum nyob ze rau qhov ntsuas tam sim no transformer. tam sim no.
Tsis tas li ntawd, qhov tsis muaj load poob xam los ntawm kev xa mus rau chav tsev poob thiab txheej txheem coefficient ntawm cov ntawv xaiv silicon steel raws li cov txheej txheem hauv kev tsim qauv feem ntau hu ua tus nqi suav. Tus nqi no yuav tsum muab piv nrog tus qauv tus nqi teev tseg hauv tus qauv lossis nrog tus qauv tus nqi lossis tus nqi lav tau teev tseg hauv daim ntawv cog lus. Tus nqi suav yuav tsum tsawg dua li tus qauv tus nqi lossis tus nqi lav, thiab yuav tsum tsis muaj qhov sib npaug hauv kev suav, tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob ntau. Tsis tas li ntawd, tus nqi suav tsuas yog siv tau rau cov neeg tsim qauv lossis cov chaw tsim khoom thiab tsis muaj kev cai lij choj. Tus nqi ntsuas tsis tuaj yeem siv los txiav txim qhov poob ntawm cov khoom. Tus qauv tus nqi teev nyob rau hauv tus qauv lossis tus nqi lav uas tau teev tseg hauv daim ntawv cog lus muaj kev cai lij choj. Cov khoom lag luam uas tshaj tus qauv tus nqi ntxiv rau qhov tso cai sib txawv, lossis tus nqi lav (tus nqi lav yog sib npaug rau tus qauv tus nqi ntxiv rau qhov tso cai sib txawv), suav tias yog cov khoom tsis tsim nyog. Yog tias muaj qhov kev ntsuam xyuas poob, feem ntau nws yuav raug taw qhia nyob rau hauv daim ntawv cog lus, tshwj xeeb tshaj yog rau cov khoom xa tawm, yog tias tus nqi poob siab tshaj li qhov tau teev tseg, yuav raug nplua, thiab kev nplua rau qhov tsis muaj kev thauj khoom yog qhov siab tshaj plaws. Qhov kev ntsuam xyuas poob ntawm cov teb chaws Europe tuaj yeem pom nyob rau hauv 11 qhov teeb meem ntawm "Transformer" magazine hauv 1994. Muaj kev nplua nyiaj ntau txhiab daus las ib kilowatt. Qhov no yog cov txiaj ntsig raug cai thiab txuas ncaj qha rau cov txiaj ntsig kev lag luam.
Lub tswv yim ntawm qhov ntsuas qhov tseeb yuav tsum to taub kom raug. Txawm hais tias kev nyeem ntawv ntawm kev sib nrig sib 'meter' (los yog kev nyeem ntawv ntawm lub hwj chim converter) los yog tus nqi ntsuas qhov tseeb yuav tsum tau hloov mus rau qhov ntsuas ntsuas, thiab yuav tsum muaj qhov tseeb txaus. Rau qhov ntsuas qhov tseeb ntawm qhov tsis muaj qhov poob, nws yog qhov tseem ceeb tias qhov hluav taws xob waveform ntawm lub zog hluav taws xob yuav tsum yog sinusoidal, thiab qhov sib txawv ntawm qhov nruab nrab voltmeter nyeem ntawv thiab qhov kev nyeem tau zoo yog tsawg dua 3%.
