Nzira yekuedza capacitor ne multimeter

18.02.2023 /

Kazhinji vanhu vanondibvunza kuti ndingaedza sei capacitor ine multimeter.

Chimiro che capacitor ndechekuchaja uye kuburitsa simba nekukurumidza kupfuura bhatiri nekuti inochengeta simba zvakasiyana, kunyangwe isingakwanise kuchengeta yakaenzana. Izvi zvinobatsira zvakanyanya uye ndosaka iwe uchigona kuwana capacitor pane angangoita ese PCB.

Iyo capacitor inochengetedza simba rinoburitswa kuti rigadzirise kudzimwa kwemagetsi.

Mukati meiyo main capacitor, tine maviri conductive mahwendefa, anowanzo gadzirwa nealuminium, akaparadzaniswa ne dielectric insulating zvinhu senge ceramic.

Dielectric zvinoreva kuti zvinhu zvinozomira kana zvasangana nemunda wemagetsi. Padivi recapacitor, iwe unowana chiratidzo uye bhaa inoratidza kuti nderipi divi (terminal) isina kunaka.

Nzira dzekuyedza capacitor ine multimeter

Kutanga iwe unofanirwa kuve nechokwadi kuti unoziva zvauri kuita. Verenga yambiro nemazvo usati washandisa idzi capacitor test nzira.

Iwe unofanirwawo kuona iwo makuru ekutadza modhi, zvinoreva kufungidzirwa kukundikana kwecapacitor, saka iwe unogona kuziva kuti ndeipi nzira yekuyedza yekushandisa:

  • Kuderedza kugona
  • Dielectric breakdown (short circuit)
  • Kurasika kwekubatana pakati pendiro nemutobvu
  • leakage current
  • Kuwedzera ESR (yakaenzana akateedzana kuramba)

Tarisa iyo capacitor ine digital multimeter

  1. Bvisa iyo capacitor kubva kune magetsi, kana kuti ita chokwadi kuti waya imwe yakabviswa.
  2. Iva nechokwadi chokuti capacitor yakasunungurwa zvakakwana. Izvi zvinogona kuwanikwa nekubatanidza ese materminals e capacitor ne screwdriver.
  3. Seta mita kune iyo ohm renji (inenge 1k ohm)
  4. Batanidza iyo multimeter inotungamira kune capacitor terminals. Ita shuwa kuti wabatanidza positive kune positive uye negative kune negative.
  5. Iyo counter icharatidza manhamba mashoma kwesekondi uye wobva wadzokera kuOL (yakavhurika mutsara). Kuedza kwega kwega mudanho rechitatu kucharatidza mhedzisiro yakafanana nedanho iri.
  6. Kana pasina shanduko, ipapo capacitor yakafa.

Tarisa iyo capacitor mune capacitance mode.

Kune iyi nzira, iwe uchada capacitance mita pane multimeter, kana multimeter ine chimiro ichi.

Iyi nzira yakanakisa yekuyedza madiki capacitor. Payedzo iyi, chinja kune chiyero.

  1. Bvisa iyo capacitor kubva kune magetsi, kana kuti ita chokwadi kuti waya imwe yakabviswa.
  2. Iva nechokwadi chokuti capacitor yakasunungurwa zvakakwana. Izvi zvinogona kuwanikwa nekubatanidza ese materminals e capacitor ne screwdriver.
  3. Sarudza "Capacity" pane yako kifaa.
  4. Batanidza iyo multimeter inotungamira kune capacitor terminals.
  5. Kana kuverenga kuri pedyo nekukosha kunoratidzwa pabhokisi remudziyo we capacitor, zvinoreva kuti capacitor iri mumamiriro akanaka. Kuverenga kungave kushoma pane kukosha chaiko kweiyo capacitor, asi izvi zvakajairika.
  6. Kana iwe usingaverenge capacitance, kana iyo capacitance yakanyanya kuderera pane kuverenga kunoratidza, iyo capacitor yakafa uye inofanira kutsiviwa.

Tarisa Capacitor ine voltage test.

Iyi ndiyo imwe nzira yekuyedza capacitor. Macapacitors anochengetedza zvinogona kusiyana mumachaji, ayo ari voltages.

A capacitor ine anode (positive voltage) uye cathode (negative voltage).

Imwe nzira yekuyedza capacitor ndeyekuchaja nevoltage uye wozotora kuverenga pane cathode uye anode. Kuti uite izvi, shandisa mhepo inogara iripo kune zvakabuda. Polarity inobata pano. Kana iyo capacitor ine zvese zvakanaka uye zvisina kunaka zviteshi, iyo polarized capacitor umo iyo yakanaka voltage ichaenda kune anode uye yakaipa voltage kune cathode.

  1. Bvisa iyo capacitor kubva kune magetsi, kana kuti ita chokwadi kuti waya imwe yakabviswa.
  2. Iva nechokwadi chokuti capacitor yakasunungurwa zvakakwana. Izvi zvinogona kuwanikwa nekuvharira ese ari maviri materminal e capacitor ane screwdriver, kunyangwe akakura macapacitor anonyatso kuburitswa kuburikidza nemutoro.
  3. Tarisa huwandu hwemagetsi akaiswa pane capacitor.
  4. Shandisa voltage, asi chenjerera kuti uone kuti voltage ishoma pane iyo capacitor yakarongerwa; somuenzaniso, unogona kushandisa 9 volt bhatiri kutengesa 16 volt capacitor uye iva nechokwadi chekubatanidza zvakanaka zvinotungamirira kune zvakanaka zvinotungamirira zve capacitor uye zvakashata zvinotungamirira kune zvakashata zvinotungamirira.
  5. Chaja iyo capacitor mumasekonzi mashoma
  6. Bvisa voltage source (bhatiri)
  7. Isa mita kuDC uye batanidza voltmeter kune capacitor, inobatanidza zvakanaka-kune-zvakanaka uye zvakashata-kune-negative.
  8. Tarisa kukosha kwekutanga voltage. Inofanira kuva pedyo nemhepo inoshandiswa kune capacitor. Izvi zvinoreva kuti capacitor iri mumamiriro akanaka. Kana kuverenga kwakanyanyisa, iyo capacitor inosunungurwa.

Iyo voltmeter icharatidza kuverenga uku kwenguva pfupi nekuti capacitor ichakurumidza kubuda kuburikidza ne voltmeter kusvika ku0V.
