Yuav ua li cas ntxiv ib qho inductance luv Circuit Court tester rau multimeter
Nws yog qhov yooj yim heev los txuas cov khoom siv 555 sib xyaw ua ke rau hauv cov lus tawm tswv yim-hom tsis ruaj khov, thiab nruab rau hauv qhov chaw hauv lub tshuab hluav taws xob los txiav txim seb lub inductor (xws li lub pob hluav taws xob siab ntawm lub TV) yog luv luv. .
Lub hauv paus ntsiab lus ntawm tester Circuit Court yog qhia nyob rau hauv daim duab. Yuav kom txuag tau qhov chaw, sim siv cov khoom me me los yog cov khoom me me. Qhib ob lub qhov nyob rau hauv qhov tsim nyog txoj hauj lwm ntawm rooj plaub, thiab nruab ib tug ob tug ncej ob chav pov hloov K thiab potentiometer W. Circuit Court ntawm lub multimeter nws tus kheej tsis muaj kev hloov. Tus neeg sau tau soldered tag nrho Circuit Court ntawm 1.5 × 3cm insulating board. Nws tau nruab rau ntawm ib sab ntawm lub taub hau sab hauv ntawm MF-47 Wangang saib thiab kho nrog cov kua nplaum kub yaj, thiab muaj ntau tshaj qhov chaw txaus hauv lub moos.
Yuav siv li cas: Feem ntau, muab qhov hloov K rau hauv txoj haujlwm "ib txwm", lub voj voog tsis ua haujlwm, thiab tsis muaj kev cuam tshuam rau kev siv ib txwm siv ntawm multimeter. Thaum lub inductance yuav tsum tau ntsuas. Teem lub multimeter rau AC10V iav, thiab hloov K mus rau "L" txoj hauj lwm. Lub sijhawm no, kho lub potentiometer W, thiab multimeter tuaj yeem muaj qhov ntsuas qhov siab tshaj plaws ntawm 4 mus rau 5V, uas tuaj yeem hu ua "tsis muaj qhov hluav taws xob". Txuas qhov kev xeem coj mus rau ob qho kawg ntawm qhov inductor yuav tsum ntsuas, thiab kho lub potentiometer kom ua kom pom qhov muaj nuj nqis tshaj plaws. Tus nqi siab tshaj plaws ntawm qhov inductance yuav ntau dua lossis tsawg dua qhov tsis muaj qhov hluav taws xob. Kev ntsuas qhov tseeb ntawm 25-inch xim TV nrog cov pob hluav taws xob siab tsis zoo, tus nqi siab tshaj plaws tuaj yeem ncav cuag 40V thaum lub sijhawm resonance, thiab qhov ntsuas qhov ntsuas tuaj yeem hloov kho rau 10V. Qhov tseeb ntsuas ntawm ib tug 17-inch dub tus kheej-tshuab tshuab tsis zoo-voltage pob thawj, qhov siab tshaj plaws voltage yog ib txwm qis dua qhov tsis muaj-load voltage. Thaum lub sij hawm xeem, siv ib tug xaim kom dhau los ntawm lub magnetic core ntawm inductor thiab ua ib tug tig. Thaum cov xaim luv luv, qhov tshwm sim ntawm qhov hluav taws xob yuav tsum poob qis heev. Yog tias qhov poob qis heev lossis txawm tias tsis poob, nws tuaj yeem txiav txim siab tias qhov ntsuas inductance nyob hauv. Muaj luv luv Circuit Court.
