Cov ntsiab lus:

Nyob rau hauv circuits, resistors yog ib qho tseem ceeb tivthaiv uas yuav txwv tsis pub khiav ntawm tam sim no thiab hloov hluav taws xob hluav taws xob rau hauv thermal zog. Thaum 380V thiab 220V voltages txuas nrog rau ob qhov kawg ntawm cov resistor, yuav muaj qee qhov sib txawv. Kab lus no yuav txheeb xyuas qhov sib txawv ntawm peb yam: qhov sib txawv ntawm qhov hluav taws xob, hluav taws xob poob, thiab kev nyab xeeb.

kev taw qhia:

Nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev loj hlob sai ntawm tib neeg, kev siv hluav taws xob tau nrov nyob hauv txhua lub ces kaum. Cov theem voltage ntawm cov khoom siv hluav taws xob kuj txawv, nrog rau qhov ntau dua yog 380V thiab 220V. Dab tsi yog qhov txawv ntawm qhov kev ua tau zoo ntawm cov resistor raws li cov khoom siv hluav taws xob yooj yim hauv Circuit Court hauv ob qhov hluav taws xob?

1, Voltage sib txawv:

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

2, Lub zog poob:

Lub hwj chim yog ib qho tseem ceeb nyob rau hauv ib lub voj voog, uas sawv cev rau tus nqi ntawm lub zog hloov mus rau ib chav tsev ntawm lub sij hawm, ntsuas hauv watts (W). Raws li lub zog formula P = IV, qhov twg P yog lub zog, kuv yog tam sim no, thiab V yog qhov hluav taws xob, nws tuaj yeem txiav txim siab tias lub zog muaj feem cuam tshuam nrog cov khoom tam sim no thiab voltage. Yog li ntawd, thaum lub zog sib txawv ntawm qhov sib txawv ntawm ob qhov kawg ntawm cov resistor, lub zog poob kuj yuav txawv. Thaum txuas nrog 380V fais fab mov, vim qhov siab tam sim no, lub zog poob kuj tseem nce ntxiv; Thaum txuas mus rau 220V fais fab mov, vim qhov me me tam sim no, lub zog poob qis kuj me me.

3, Kev ruaj ntseg:

Kev nyab xeeb yog ib qho kev txhawj xeeb tshwj xeeb thaum siv circuits. Thaum lub 380V fais fab mov txuas rau ntawm ob qho kawg ntawm cov resistor, qhov kev puas tsuaj rau tib neeg lub cev yog nce ntxiv vim yog qhov siab tam sim no. Kev sib tsoo hluav taws xob tuaj yeem ua rau raug mob hnyav lossis txawm tias muaj kev phom sij rau lub neej. Yog li ntawd, thaum txuas mus rau lub high-voltage fais fab mov yuav tsum tau coj mus rau hauv tus account qhov kev ruaj ntseg ntsuas, xws li tsim nyog Circuit Court tsim, rwb thaiv tsev tiv thaiv, thiab lwm yam. Thaum txuas mus rau ib tug 220V fais fab mov, vim hais tias ntawm lub me me tam sim no, kev ruaj ntseg yog kuj siab. .

Cov ntsiab lus:

Raws li cov khoom tseem ceeb hauv Circuit Court, cov resistors yuav muaj qee qhov sib txawv thaum txuas nrog 380V thiab 220V lub zog hluav taws xob ntawm ob qho kawg. Thaum txuas mus rau 380V fais fab mov, qhov tam sim no siab, lub zog poob siab, thiab kev nyab xeeb kev nyab xeeb kuj nce ntxiv; Thaum txuas nrog 220V fais fab mov, qhov tam sim no kuj me me, lub zog poob yog qhov me me, thiab kev nyab xeeb yog qhov siab. Yog li ntawd, thaum tsim circuits, nws yog ib qho tsim nyog yuav tau xaiv cov qib sib txawv raws li qhov xav tau tiag tiag thiab ua raws li kev ntsuas kev nyab xeeb thaum siv tiag tiag kom ntseeg tau tias kev ua haujlwm ntawm lub voj voog thiab kev nyab xeeb ntawm tus kheej.

Nco tseg: Kab lus no tsuas yog siv rau kev siv xwb, thiab cov xwm txheej tshwj xeeb yuav tsum tau txiav txim siab thiab ua raws li qhov xav tau tiag tiag thiab kev tsim hluav taws xob tshwj xeeb.
