1, Taw qhia rau Transformer
Transformer yog ib qho khoom siv hluav taws xob uas hloov cov hluav taws xob siab mus rau qhov tsis tshua muaj hluav taws xob, dav siv hauv cov teb xws li voltage transformer, tam sim no transformer, thiab lub zog ntsuas. Lub hauv paus ntsiab lus ntawm kev ua haujlwm transformer yog siv lub hauv paus ntsiab lus ntawm electromagnetic induction los hloov cov teeb liab siab voltage rau hauv cov teeb liab tsis tshua muaj hluav taws xob los ntawm kev sib nqus resonance, thiaj li ua tau raws li ntau yam kev xav tau ntawm lub zog hluav taws xob.
2, Voltage ampere yam ntxwv ntawm transformer
Lub volt ampere yam ntxwv nkhaus ntawm lub transformer yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm transformer. Lub npe hu ua volt ampere yam ntxwv yog hais txog cov kev hloov pauv tam sim no ntawm qhov tso zis kawg thaum cov hluav taws xob sib txawv raug siv rau qhov kawg ntawm qhov hloov pauv. Lub volt ampere yam ntxwv nkhaus ntawm lub transformer feem ntau sawv cev los ntawm kev sim cov ntaub ntawv, uas sau cov kev sib raug zoo ntawm cov zis voltage thiab tso zis tam sim no ntawm lub transformer nyob rau hauv txawv loads. Feem ntau, qhov voltage ampere yam ntxwv nkhaus ntawm lub transformer yuav muab faib ua peb ntu: saturation zone, linear zone, thiab oversaturation zone. Ntawm lawv, thaj tsam saturation yog hais txog lub xeev uas cov zis tam sim no ntawm lub transformer saturates nrog rau qhov nce ntawm input voltage; Linear cheeb tsam yog hais txog lub xeev uas cov zis tam sim no ntawm lub transformer sib txawv linearly nrog cov input voltage; Lub oversaturation cheeb tsam yog hais txog cov yam ntxwv nonlinear uas tshwm sim thaum cov zis tam sim no ntawm lub transformer nce nrog cov input voltage.
3, Qhov tseem ceeb ntawm voltage ampere yam ntxwv nkhaus ntawm transformer
Qhov tseem ceeb ntawm qhov voltage ampere yam ntxwv nkhaus ntawm lub transformer yog tias nws muaj peev xwm cuam tshuam cov hluav taws xob kev ua tau zoo thiab cov yam ntxwv ntawm transformer. Feem ntau, qhov voltage ampere tus yam ntxwv nkhaus ntawm lub transformer yog tiaj tus, thiab txoj kab nqes nyob rau hauv linear cheeb tsam yog me me, qhia tau hais tias lub transformer muaj ib tug tsawg nyob rau hauv tsis kam thiab zoo hluav taws xob kev ua tau zoo. Hauv cheeb tsam saturation, cov zis tam sim no ntawm lub transformer maj mam saturates nrog qhov nce ntawm input voltage, uas qhia txog qhov saturation voltage ntawm transformer lub magnetic core. Nyob rau hauv cheeb tsam oversaturated, cov zis tam sim no ntawm lub transformer yog heev cuam tshuam, inductance tus nqi txo, thiab nws yog ib qho yooj yim ua rau overvoltage, overcurrent, thiab lwm yam teeb meem nyob rau hauv lub hwj chim system.
Qhov voltage ampere yam ntxwv nkhaus ntawm lub transformer kuj siv tau los txiav txim siab load ntawm lub transformer, uas yog qhov tseem ceeb tshaj plaws parameter nyob rau hauv kev xaiv thiab daim ntawv thov ntawm lub transformer. Thaum lub transformer nyob rau hauv cheeb tsam linear, cov zis tam sim no yog proportional rau lub input voltage, thiab transformer ua hauj lwm stably feem ntau thiab cov load xaiv kuj yog qhov tsim nyog tshaj plaws. Yog li ntawd, nkag siab txog qhov voltage ampere yam ntxwv nkhaus ntawm lub transformer yog lub hauv paus rau xaiv ib tug haum transformer.
4, Daim ntawv thov ntawm Voltage Ampere Yam ntxwv nkhaus ntawm Transformer
Qhov voltage ampere yam ntxwv nkhaus ntawm transformers yog dav siv nyob rau hauv lub hwj chim systems. Ua ntej, kev xaiv ntawm transformers nyob rau hauv lub hwj chim system yuav tsum xav txog lawv volt ampere yam ntxwv curves kom tau raws li cov kev xav tau kev pab thiab nyiaj txiag ntawm lub system. Qhov thib ob, kev debugging thiab kev saib xyuas kev ua haujlwm ntawm cov transformers kuj yuav tsum tau siv lawv cov volt ampere cov yam ntxwv nkhaus los tshuaj xyuas thiab ntsuas lawv cov haujlwm ua haujlwm. Thaum kawg, qhov voltage ampere yam ntxwv nkhaus ntawm lub transformer kuj tseem siv tau los kuaj xyuas qhov tsis ua haujlwm hauv lub zog hluav taws xob, txhim kho kev ua haujlwm ntawm lub zog hluav taws xob, thiab txo qhov tshwm sim ntawm kev raug mob.
