Ntsiab lus:

Nyob rau hauv circuits, resors yog ib qho tseem ceeb uas tuaj yeem txwv qhov ntws ntawm tam sim no thiab hloov hluav taws xob lub zog rau hauv lub zog thermal. Thaum 380v thiab 220V voltages tau txuas rau ob qho kawg ntawm lub resistor, yuav muaj qee qhov sib txawv. Kab lus no yuav soj ntsuam cov kab sib txawv ntawm peb yam: voltage sib txawv, kev poob hwj chim, thiab kev nyab xeeb.

Taw qhia:

Nrog kev nce qib txuas ntxiv ntawm thev naus laus zis thiab kev loj hlob sai ntawm tib neeg, khoom siv fais fab muaj tau nrov hauv txhua lub ces kaum. Lub zog hluav taws xob ntawm lub zog hluav taws xob tseem yuav txawv, nrog ntau qhov yog 380V thiab 220V. Dab tsi yog qhov sib txawv ntawm kev ua tau zoo ntawm lub resistor vim tias lub tshuab hluav taws xob hluav taws xob hauv tsev hauv qab ob qho hluav taws xob tsawg?

1, voltage sib txawv:

Voltage hais txog qhov sib txawv, ntsuas hauv volts (v). 380V thiab 220V thiab 220V thiab 220V thiab 220V thiab 220V thiab 220V thiab 220V thiab 220v thiab 220V feem ntau sawv cev rau lub zog hluav taws xob, uas txhais tau tias qhov hluav taws xob sib txawv ntawm ob kawg ntawm lub resistor kuj sib txawv hauv ob kis. Raws li Ohm txoj cai, kev sib txheeb ntawm cov hluav taws xob voltage thiab tam sim no yog U = ir, qhov twg koj yog qhov hluav taws xob, Kuv yog tam sim no, thiab r yog tsis kam. Nws tuaj yeem pom tias nyob rau hauv tib qho kev tiv thaiv, thaum txuas nrog 380V fais fab mov, tam sim no yuav loj dua li thaum txuas nrog qhov sib txawv uas ua rau muaj kev hloov pauv tam sim no. Yog li ntawd, thaum lub band tsis kam txuas nrog lub zog hluav taws xob nrog sib txawv ntawm ob qho kawg, yuav muaj qhov sib txawv ntawm qhov ntau ntawm tam sim no.

2, Lub zog poob:

Lub hwj chim yog qhov tseem ceeb hauv Circuit Court, uas sawv cev rau cov kev hloov pauv hluav taws xob ib chav ntawm lub sijhawm, ntsuas hauv watts (w). Raws li lub hwj chim Miskas P = IV, qhov twg P yog lub zog, thiab V yog voltage, nws tuaj yeem txiav txim siab tias lub zog ntawd cuam tshuam nrog cov khoom ntawm tam sim no thiab hluav taws xob. Yog li ntawd, thaum sib txawv lub zog sib txuas tau txuas rau ob qho kawg ntawm lub resistor, lub zog poob tseem yuav txawv. Thaum txuas nrog rau 380V fais fab mov, vim yog qhov siab tam sim no, lub zog poob tseem yuav nce raws li; Thaum sib txuas rau 220V fais fab mov, vim qhov me me tam sim no, lub zog poob yog me me.

3, Kev Ruaj Ntseg:

Kev nyab xeeb yog kev txhawj xeeb tshwj xeeb thaum siv cov kab ncig. Thaum muaj 380V fais fab mov yog txuas rau ntawm ob kawg ntawm lub resistor, qhov kev ua phem rau tib neeg lub cev yog nce ntxiv vim yog qhov siab tam sim no. Fais fab kev huam yuaj yuav ua rau raug mob hnyav lossis txawm tias muaj sia nyob. Yog li ntawd, thaum txuas txuas rau lub zog hluav taws xob ntau, ntsuas kev tiv thaiv kev nyab xeeb, thiab kev sib txuas tau yooj yim, vim muaj kev nyab xeeb me me Cov.

Ntsiab lus:

Raws li cov khoom siv tseem ceeb hauv Circuit Court, cov neeg tawm tsam muaj qee qhov sib txawv thaum txuas nrog 380V thiab 220V lub zog muaj peev xwm ntawm ob qho kawg. Thaum sib txuas rau 380V fais fab mov, tam sim no yog siab, lub zog ploj yog siab, thiab kev nyab xeeb kev nyab xeeb yog qhov nce ntxiv; Thaum txuas nrog 220V fais fab mov, qhov tam sim no yog me me, lub zog poob yog me me, thiab kev nyab xeeb yog qhov siab. Yog li ntawd, thaum tsim cov khoom siv, nws yog qhov tsim nyog los xaiv cov kev xav sib txawv raws li kev xav tau ua kom paub tseeb tias kev ua haujlwm ntawm Circuit Court thiab kev nyab xeeb ntawm tus kheej.

Nco tseg: Kab lus no tsuas yog siv rau kev siv xwb, thiab tshwj xeeb cov xwm txheej yuav tsum raug txiav txim thiab daws tau cov kev xav tau tiag tiag thiab tshwj xeeb.
