Daim ntawv thov ntawm clamp ammeter hauv hluav taws xob kuaj xyuas
1. Txheeb xyuas qhov polarity ntawm tam sim no transformer circuit
Thaum siv tus qauv watt-teev ntsuas ntsuas los kuaj xyuas qhov kev khiav haujlwm siab-voltage watt-teev ntsuas ntawm qhov chaw, yog tias koj xav tau xyuas qhov tseeb ntawm qhov polarity ntawm tam sim no transformer circuit, koj tuaj yeem siv lub clamp-on AC ammeter los txiav txim.
2. Rau peb-theem peb-xaim watt-teev meter, thawj clamp thiab ntsuas qhov A thiab C theem tam sim no txuas nrog tus qauv ntsuas raws, thiab cov nqi yuav tsum sib npaug lossis zoo sib xws. Tom qab ntawd clamp lub vector sum ntawm theem A thiab C, yog tias nws tus nqi sib npaug los yog ze rau tus nqi ntawm theem A thiab C, nws txhais tau hais tias ob theem yuav tsum clamped yog tib lub polarity, yog tias nws sib npaug los yog ze. mus rau theem A thiab C, kaum txhiab zaus, ces ob theem ntsuas los ntawm lub clamp yog qhov sib txawv polarity.
Rau peb-theem plaub-hlau watt-teev meter, A, B, C, thiab theem tam sim no yuav tsum tau clamped ua ntej, thiab lawv cov nqi yuav tsum sib npaug los yog zoo sib xws. Tom qab ntawd ntsuas cov vector sum ntawm peb theem A, B, thiab C. Tus nqi yog xoom, qhia tias lub polarity ntawm peb theem yuav tsum tau clamped yog tib yam. Ib lossis ob ntawm peb theem yog ntsuas nyob rau hauv rov qab polarity.
Nyob rau hauv tib txoj kev, yog tias muaj lwm yam kev kuaj xyuas ntawm cov khoom siv khiav ntawm qhov chaw, tsuav yog qhov thib ob ntawm qhov tam sim no transformer koom nrog, los yog △ kev twb kev txuas thiab △ kev twb kev txuas yog lawm, txoj kev saum toj no kuj siv tau.
Tshawb xyuas thyristor thiab silicon rectifier Cheebtsam
Thaum lub sijhawm ua haujlwm ntawm thyristor lossis silicon rectifier caij, lub zog DC tam sim no ntws, thiab nws qhov loj me hloov nrog lub sijhawm, yog li nws tuaj yeem kuaj pom los ntawm AC clamp ammeter.
Thaum kuaj xyuas, tsuas yog clamp qhov zoo lossis qhov tsis zoo ntawm lub ntsiab ntawm txhua lub thyristor lossis silicon rectifier lub caij, thiab txiav txim seb lub caij puas zoo raws li qhov muaj lossis tsis muaj thiab qhov loj ntawm qhov kev nyeem tam sim no. Yog tias qhov kev nyeem ntawv ntawm lub ntsuas clamp yog xoom, nws txhais tau hais tias cov khoom siv tsis ua haujlwm, txawm tias lub thyristor trigger Circuit Court tsis raug, lossis cov khoom puas, lossis lub fuse core yuav raug tshuab. Conversely, yog hais tias tam sim no qhov tseem ceeb ntawm peb-theem Cheebtsam yog qhov tseem ceeb sib npaug, nws qhia tau hais tias lub ntsiab Circuit Court thiab lub thyristor trigger Circuit Court ua hauj lwm ib txwm. Yog hais tias peb-theem tam sim no tsis muaj qhov sib npaug, nws yuav yog tias qhov cuam tshuam ntawm lub thyristor tsis tau debugged zoo, los yog tej zaum yuav muaj ib qho txhaum ntawm AC ib feem ntawm lub rectifier ntaus ntawv, piv txwv li, ib theem ntawm lub rectifier transformer. yog txiav, thiab lwm yam.
