Txoj Kev Siv Hluav Taws Xob thiab Txoj Cai Ua Haujlwm ntawm Tib-Phase Watt-Hour Meter
Ib-theem hluav taws xob ntsuas hluav taws xob, siv hauv kev ntsuas lub zog. Kev ntsuas qhov tseeb, kev hloov pauv thiab qhov me me (18mm), tuaj yeem ntsia tau yooj yim hauv ntau lub thawv xa khoom. DIN-rail mounting, hauv qab thaiv, zoo kawg nkaus txuam nrog me me Circuit Court breakers. Intuitive thiab yooj yim-rau-nyeem cov neeg kho tshuab tso saib txo qhov kev pheej hmoo ntawm cov ntaub ntawv poob hauv kev npaj txhij txog hluav taws xob. Tsis xav tau kev khiav hauj lwm fais fab sab nraud. Kev khiav hauj lwm kub ntau yam.
Ib-theem watt-teev meter yog ib hom watt-teev meter. Lub ntsiab qauv ntawm lub watt-teev meter yog tsim los ntawm ib tug voltage coil, ib tug tam sim no kauj, turntable, ib tug tig ncej, brake magnet, iav, thiab ib tug 'meter'. Ib-theem meters feem ntau yog siv rau pej xeem siv, txuas nrog 220V khoom siv. Lub watt-teev meter siv cov eddy tam sim no generated los ntawm qhov voltage thiab tam sim no coils ntawm txhuas phaj los cuam tshuam nrog alternating magnetic flux los tsim electromagnetic quab yuam kom lub txhuas phaj tig. Nyob rau tib lub sij hawm, lub braking torque yog qhia, yog li ntawd lub ceev ntawm aluminium disc yog proportional rau lub load zog. Los ntawm axial iav kis tau tus mob, lub zog hluav taws xob yog ntsuas los ntawm accumulating tus naj npawb ntawm revolutions ntawm lub turntable los ntawm lub txee.
Lub hauv paus ntsiab lus ntawm watt-teev meter:
Thaum lub watt-teev meter txuas nrog lub voj voog nyob rau hauv kev sim, qhov voltage U ntawm Circuit Court nyob rau hauv kev xeem yog siv rau lub voltage kauj, tsim ib tug alternating magnetic flux nyob rau hauv nws cov hlau core. Ib feem ntawm qhov flux no, ΦU, dhau los ntawm txhuas disk los ntawm tus ncej xa rov qab mus rau cov tub ntxhais hlau rov qab mus rau qhov hluav taws xob coil. Ib yam li ntawd, tom qab qhov tam sim no kuv ntawm Circuit Court nyob rau hauv kev xeem dhau los ntawm lub kauj tam sim no, ib qho kev sib nqus sib nqus flux Φi kuj tsim nyob rau hauv U-shaped hlau core ntawm lub kauj tam sim no. Qhov sib nqus flux no yog tsim los ntawm U-zoo li qhov kawg ntawm cov tub ntxhais hlau thiab dhau los ntawm txhuas disk los ntawm hauv qab mus rau sab saum toj, thiab tom qab ntawd dhau los ntawm txhuas disk los ntawm sab saum toj mus rau hauv qab thiab rov qab mus rau lwm qhov kawg ntawm U-shaped hlau core. .
Cov hlau nplaum rov qab phaj 4 yog xuas nrig ntaus los ntawm lub phaj hlau, thiab nws qhov qis kawg txuas mus rau sab qis ntawm cov phaj txhuas, sib haum rau cov hlau tub ntxhais kem sib cais los ntawm txhuas phaj thiab cov khoom siv hluav taws xob, thiaj li tsim tau ib lub voj voog ntawm cov hlau nplaum. ua hauj lwm sib nqus flux ntawm voltage coil. Txij li thaum ob qhov sib nqus fluxes dhau los ntawm txhuas disk yog alternating magnetic fluxes thiab dhau los ntawm txhuas disk ntawm ntau txoj haujlwm, induced eddy currents yog generated nyob ze ntawm cov hauj lwm uas lawv dhau los ntawm txhuas disk. Kev sib cuam tshuam ntawm ob qhov sib nqus fluxes nrog cov eddy tam sim no ua rau lub zog sib hloov ntawm cov txhuas disk uas thawb cov txhuas disk kom tig.
Ib-theem watt-teev 'meter' txuas txoj kev:
Muaj ob txoj kev xaim rau lub ntsuas watt-teev: dhia-hauv kev sib txuas thiab shun-hauv kev sib txuas;
Ob txoj kev xaim no tsis zoo ib yam ntawm qhov chaw, tab sis lub hauv paus ntsiab lus sab hauv yog tib yam, uas yog, tam sim no coil ntawm ammeter txuas nrog hauv series nrog lub voj voog. Thaum lub qhov hluav taws xob hluav taws xob txuas nrog rau qhov sib npaug nrog lub nra, qhov "*" kawg ntawm ob lub coils yuav tsum txuas nrog tib lub polarity kawg ntawm lub hwj chim mov. Feem ntau, ib-theem watt-teev meter muaj ib lub thawv tshwj xeeb. Thaum koj qhib lub thawv npog, koj tuaj yeem pom tias muaj plaub lub davhlau ya nyob twg khawm. Txoj kev xaim tiag tiag yuav tsum tau ua raws li cov cai hauv watt-teev meter phau ntawv.
Hauv ib-theem circuits uas tsis tshua muaj hluav taws xob thiab tsis tshua muaj tam sim no, lub watt-teev meter tuaj yeem txuas ncaj qha rau kab. Yog hais tias lub load tam sim no loj heev los yog qhov voltage siab heev, nws yuav tsum tau txuas nrog lub Circuit Court los ntawm lub transformer. Lub sij hawm no, thawj sab ntawm lub tam sim no transformer yog txuas nrog nyob rau hauv series nrog lub load, lub thib ob sab yog kev cob cog rua nyob rau hauv series nrog lub tam sim no kauj ntawm lub watt-teev 'meter', thawj sab ntawm lub voltage transformer yog txuas nrog nyob rau hauv parallel. load, thiab ob sab yog kev cob cog rua nyob rau hauv parallel nrog lub voltage kauj ntawm lub watt-teev meter.
Yuav ua li cas siv ib-theem watt-teev meter
1. Tsim nyog xaiv watt-teev meter: Ua ntej, xaiv ib theem lossis peb-theem watt-teev meter raws li txoj haujlwm. Rau peb-theem watt-teev meter, nws yuav tsum tau xaiv raws li seb txoj kab hauv qab kev sim yog peb-theem peb-xaim los yog peb-theem plaub-xaim system. Qhov thib ob yog qhov kev xaiv ntawm qhov ntsuas hluav taws xob thiab tam sim no, thiab qhov ntsuas hluav taws xob thiab qhov tam sim no yuav tsum sib npaug los yog tsawg dua nws cov nqi ntsuas.
2. Txhim kho lub watt-teev meter: Lub watt-teev meter feem ntau yog nruab nrog cov khoom siv hluav taws xob, thiab lub watt-teev meter yuav tsum tau nruab rau hauv qab ntawm cov khoom siv hluav taws xob, thiab nws qhov chaw nruab nrab yog 1.5 txog 1.8 meters deb ntawm av. . Thaum txhim kho ntau watt-teev meters ib sab ntawm ib sab, qhov kev ncua deb ntawm ob meters yuav tsum tsis txhob tsawg tshaj li 200 hli. Meters yuav tsum tau muab cais rau cov kab hluav taws xob nrog cov nqi hluav taws xob sib txawv. Cov kab hluav taws xob nrog tib tus nqi hluav taws xob yuav tsum tau ua ke nrog cov meters. Thaum txhim kho lub watt-teev 'meter', lub 'meter' lub cev yuav tsum tau perpendicular rau hauv av, txwv tsis pub nws qhov tseeb yuav raug cuam tshuam.
3. Kev xaim kom raug: Raws li qhov yuav tsum tau muaj ntawm phau ntawv qhia thiab daim duab thaiv, cov xaim xaim tuaj thiab tawm yuav tsum tau txuas nrog lub qhov hluav taws xob ntawm watt-teev meter nyob rau hauv lem. Thaum xaim, ua tib zoo saib rau theem kev sib raug zoo ntawm cov khoom siv hluav taws xob, tshwj xeeb tshaj yog cov reactive watt-teev meter, thiab xyuam xim rau cov theem sib lawv liag.
