Ungayihlola kanjani i-capacitor nge-multimeter

Ngokuvamile abantu bayangibuza ukuthi ngivivinya kanjani i-capacitor nge-multimeter.

Imvelo ye-capacitor ukushaja nokukhulula amandla ngokushesha kunebhethri ngoba igcina amandla ngendlela ehlukile, nakuba ingakwazi ukugcina inani elifanayo. Lokhu kuwusizo kakhulu futhi yingakho ungathola i-capacitor cishe kuwo wonke ama-PCB.

I-capacitor igcina amandla akhishiwe ukuze kusheleleke ukuphuma kukagesi.

Ngaphakathi kwe-capacitor eyinhloko, sinamapuleti amabili e-conductive, ngokuvamile enziwe nge-aluminium, ahlukaniswe ngezinto zokuvikela i-dielectric ezifana ne-ceramic.

I-Dielectric isho ukuthi impahla izohluka lapho ixhumene nenkundla kagesi. Eceleni kwe-capacitor, uzothola uphawu nebha ekhombisa ukuthi yiluphi uhlangothi (ukuphela) olunegethivu.

Izindlela zokuhlola i-capacitor nge-multimeter

Okokuqala kufanele uqinisekise ukuthi uyakwazi okwenzayo. Funda izexwayiso ngokucophelela ngaphambi kokusebenzisa lezi zindlela zokuhlola i-capacitor.

Kufanele futhi unqume izindlela eziyinhloko zokwehluleka, okusho ukwehluleka okusolwayo kwe-capacitor, ukuze wazi ukuthi iyiphi indlela yokuhlola okufanele uyisebenzise:

• Ukuncishiswa kwamandla
• Ukuqhekeka kwe-Dielectric (isifunda esifushane)
• Ukulahlekelwa ukuxhumana phakathi kwepuleti nomthofu
• ukuvuza kwamanje
• Ukwenyuka kwe-ESR (ukumelana nochungechunge okulingana)

Hlola i-capacitor nge-multimeter yedijithali

1. Nqamula i-capacitor kumandla kagesi, noma okungenani uqinisekise ukuthi intambo eyodwa inqanyuliwe.
2. Qinisekisa ukuthi i-capacitor ikhishwe ngokuphelele. Lokhu kungafezwa ngokuxhuma zombili iziphetho ze-capacitor nge-screwdriver.
3. Setha imitha kububanzi be-ohm (okungenani 1k ohm)
4. Xhuma i-multimeter iholela kumatheminali e-capacitor. Qinisekisa ukuthi uxhuma okuthi positive kuya kokuhle kanye negethivu kuya kokubi.
5. Ikhawunta izokhombisa amadijithi ambalwa umzuzwana bese ibuyela ngokushesha ku-OL (umugqa ovulekile). Umzamo ngamunye esinyathelweni sesi-3 uzobonisa umphumela ofanayo njengalesi sinyathelo.
6. Uma kungekho shintsho, i-capacitor ifile.

Hlola i-capacitor kumodi ye-capacitance.

Ngale ndlela, uzodinga imitha ye-capacitance ku-multimeter, noma i-multimeter enalesi sici.

Le ndlela ingcono kakhulu yokuhlola ama-capacitor amancane. Kulokhu kuhlolwa, shintshela kumodi yomthamo.

1. Nqamula i-capacitor kumandla kagesi, noma okungenani uqinisekise ukuthi intambo eyodwa inqanyuliwe.
2. Qinisekisa ukuthi i-capacitor ikhishwe ngokuphelele. Lokhu kungafezwa ngokuxhuma zombili iziphetho ze-capacitor nge-screwdriver.
3. Khetha "Umthamo" kudivayisi yakho.
4. Xhuma i-multimeter iholela kumatheminali e-capacitor.
5. Uma ukufundwa kuseduze nenani elikhonjiswe ebhokisini lesitsha se-capacitor, kusho ukuthi i-capacitor isesimweni esihle. Ukufundwa kungase kube ngaphansi kwenani langempela le-capacitor, kodwa lokhu kuvamile.
6. Uma ungafundi i-capacitance, noma uma i-capacitance ingaphansi kakhulu kunalokho okushiwo ukufundwa, i-capacitor ifile futhi kufanele ishintshwe.

Hlola I-Capacitor ene-voltage test.

Lena enye indlela yokuhlola i-capacitor. Ama-Capacitor agcina umehluko ongaba khona ezindlekweni, okungama-voltage.

I-capacitor ine-anode (i-voltage positive) kanye ne-cathode (i-voltage negative).

Enye indlela yokuhlola i-capacitor ukuyishaja nge-voltage bese uthatha ukufundwa ku-cathode ne-anode. Ukuze wenze lokhu, sebenzisa i-voltage engaguquki emiphumeleni. I-polarity ibalulekile lapha. Uma i-capacitor inama-terminals amahle kanye nama-negative, i-polarized capacitor lapho i-voltage eqondile izoya ku-anode kanye ne-voltage engalungile ku-cathode.

1. Nqamula i-capacitor kumandla kagesi, noma okungenani uqinisekise ukuthi intambo eyodwa inqanyuliwe.
2. Qinisekisa ukuthi i-capacitor ikhishwe ngokuphelele. Lokhu kungafezwa ngokuvala womabili amatheminali e-capacitor nge-screwdriver, nakuba ama-capacitor amakhudlwana ekhishwa kangcono ngomthwalo.
3. Hlola ububanzi be-voltage emakwe ku-capacitor.
4. Faka i-voltage, kodwa qaphela ukuze uqiniseke ukuthi i-voltage ingaphansi kwalokho okulinganiselwe i-capacitor; isibonelo, ungasebenzisa ibhethri ye-volt engu-9 ukushaja i-16 volt capacitor futhi uqiniseke ukuthi uxhuma i-positive iholela emithonjeni emihle ye-capacitor futhi i-negative iholela emithonjeni engalungile.
5. Shaja i-capacitor ngemizuzwana embalwa
6. Khipha umthombo we-voltage (ibhethri)
7. Setha imitha ku-DC bese uxhuma i-voltmeter ku-capacitor, exhumanisa okuhle kuya kokuhle nokunegethivu kuya kokubi.
8. Hlola inani lamandla kagesi lokuqala. Kufanele isondele ku-voltage esetshenziswa ku-capacitor. Lokhu kusho ukuthi i-capacitor isesimweni esihle. Uma ukufundwa kuphansi kakhulu, i-capacitor iyakhishwa.

I-voltmeter izobonisa lokhu kufundwa isikhathi esifushane kakhulu ngoba i-capacitor izokhipha ngokushesha nge-voltmeter ukuya ku-0V.
