Dab tsi yog qhov sib txawv ntawm cov ntau thiab cov buzzer ntau ntawm kev ncua txuas ntxiv rau kev sib txuas lus sib txuas?
Ntau tus phooj ywg nyiam siv hom beep los txiav txim siab txuas ntxiv ntawm Circuit Court lossis cov phooj ywg zoo tshaj plaws los txiav txim siab txuas ntxiv ntawm Circuit Court lossis qhov zoo ntawm cov khoom siv. Qhov ntawd yog cov lus nug, dab tsi yog qhov sib txawv ntawm multimeter tsis kam hom thiab lub buzzer hom thaum ntsuas rau / tawm?
Qhov sib txawv ntawm lawv yog:
Cov kev tawm tsam ntau ntawm cov neeg sib sau ua tau los ntsuas qhov tshwj xeeb ntawm cov Circuit Court, thiab tom qab ntawd peb tuaj yeem txheeb xyuas seb puas yog qhov kev ua txhaum cai raws li cov nqi tiv taus.
Lub suab nrov hom tsuas yog txiav txim siab seb qhov puas kam ntawm Circuit Court yog qhov siab lossis qis dua {} Thiab muaj qee qhov sib txawv nyob ntawm qhov sib txawv ntawm lub motimeter).
Piv txwv tias yog qhov tseem ceeb tshaj plaws tus nqi rau pulit lub suab beep yog tsawg dua 50 ω, thiab cov khoom lag luam beep yog tsawg dua 50 ω, thiab cov suab me me, ntau dua lub suab beep. Tab sis thaum cov tsis kam ntawm Circuit Court lossis thauj khoom yog ntau dua 50 ω, hom buzzing yuav tsis suab. Yog li thaum cov tsis kam ntawm Circuit Court yog ntau dua 50 ω lossis ∞, peb tsis tuaj yeem paub qhov txawv nws siv cov hom buzer.
Kev txiav txim siab zoo ntawm ib leeg-theem motors
Ib nrab-theem lub cev muaj zog muaj ob kauj windings, ib qho yog pib winding thiab lwm tus yog kev winding. Vim tias cov tuab khiav kev khiav rog winding coil thiab thasterner pib winding coil, cov nqi tiv thaiv ntawm kev pib pib ntau dua li cov winding. Cov nqi tiv thaiv tshwj xeeb yog nyob ntawm tus qauv muaj zog thiab lub zog, xws li los ntawm kaum tawm ntawm ib lossis ob puas ohms. (Ntau dua lub zog lub zog, qhov me me ntawm kev tiv taus; tus me dua lub zog, qhov loj dua cov tsis kam)
Yog tias lub zog ntawm lub cev muaj zog yog tsawg heev, nws tus nqi tiv taus yuav siab heev. Yog tias tus nqi tiv thaiv tau loj dua 50 ω, qhov txiaj ntsig peb ntsuas siv cov hom buzzer yuav tsis nrov. Ib yam li ntawd, yog tias lub cev muaj zog window tawm, peb yuav tsis ua ib lub suab txawm tias thaum siv lub buzzer hom rau kev sim.
Yog tias lub cev muaj zog muaj lub zog siab, nws txoj kev tawm tsam yuav tau me me. Yog tias qhov tsis kam yog tsawg dua 50 ω, qhov txiaj ntsig peb ntsuas siv cov hom buzzer yog tias muaj suab nrov nrov. Ib yam li ntawd, yog tias muaj luvfmfath tshwm sim nyob hauv nruab nrab ntawm lub cev muaj zog winding, qhov tshwm sim peb ntsuas siv lub suab nrov buzzer tseem siv lub suab nrov.
Yog li, rau qhov xwm txheej uas koj tau hais, nws yog tiag tiag tsis yooj yim sua kom txiav txim seb lub cev muaj zog yog qhov zoo lossis tsis zoo. Txhawm rau txiav txim siab qhov zoo ntawm lub cev muaj zog, nws yog qhov tsim nyog los soj ntsuam nws raws li kev sib xyaw ntawm lub cev muaj zog thiab lub zog.
Rau cov phooj ywg hluav taws xob uas nyuam qhuav tau pib siv motimeter, kuv xav tias thaum ntsuas cov voj voog lossis thauj nrog kev siv hom tsis kam lees cov hom buzzer. Qhov no muaj txiaj ntsig zoo heev rau kev kho thiab ua kom muaj ntau tus multimeter. Tsuas yog tom qab koj tau mastered daim ntawv thov ntawm kev siv ntau qhov kev ntsuas tsis kam, koj puas tuaj yeem siv cov hom buzzer los txhim kho kev kho kom zoo nkauj.
