Kuonekwa kweElectrolytic Capacitor muInuction Inonyungudutsa Vira

(1) Shandisa iyo multimeter ohmic block kubhadharisa iyo electrolytic capacitor kumberi uye zvinopesana. Iko kukura kweiyo swing amplitude yemudzi saw pointer kurudyi inogona kushandiswa kuyera kugona kweiyo electrolytic capacitor. Nekuda kwesimba rakakura remagetsi emagetsi, masosi akakodzera anofanirwa kusarudzwa pamatanho akasiyana kana achiyera. Zvinoenderana neruzivo, kazhinji, iyo capacitance ye 1-47uF inogona kuyerwa neRX100 giya. …

(2) Batanidza iyo tsvuku bvunzo inotungamira yeiyo multimeter kune isina kunaka danda uye dema bvunzo inotungamira kune yakanaka danda. Panguva yekutaurirana, iyo pointer yeiyo multimeter inozotsaukira kurudyi nedhigiri rakakura (yeiyo imwechete ohm giya, iyo yakanyanya kugona, iyo yakanyanya kusvetuka), uye wozofamba zvishoma nezvishoma wakananga Kutendeuka kuruboshwe kusvikira yamira pane imwe nzvimbo. Kuramba panguva ino ndiko kumberi kwekudzivirira kweiyo electrolytic capacitor, iri yakati kurei kupfuura iyo reverse leakage resistance. Chiitiko chinoshanda chinoratidza kuti kusagadzikana kwekudonha kwema electrolytic capacitors kunowanzo kuve anopfuura mazana emazana makiloohms; kana zvisina kudaro, hazvishande nemazvo. Mune tauro rekuyedza, kana pasina kubhadharisa kumberi uye kumashure nzira, ndokuti, pointer haifambe, zvinoreva kuti kugona kwacho kwanyangarika kana dunhu remukati rakabviswa; kana iyo yakayerwa kuramba kukosha iri diki kwazvo kana zero, zvinoreva kuti iyo capacitor ine yakawanda leakage kana yakaputswa pasi. , Haichakwanise kushandiswa. Ku

(3) Yezve electrolytic capacitors ine zvisingazivikanwe zvakanaka uye zvisina kunaka zviratidzo, nzira iri pamusoro yekuyera kupokana kwekudonha inogona kushandiswa kusiyanisa. Ndiko kuyera kusagadzikana kwekumanikidza, rangarira saizi yayo, uyezve wochinjana iyo bvunzo inotungamira kuyera kukosha kwekudzivirira. Iko kukurira kukuru kwezviyero zviviri ndiko kubatana kwakanaka, ndiko kuti, iyo nhema bvunzo lead inotungamirwa kune yakanaka electrode, uye iyo tsvuku bvunzo lead inosungirirwa kune isina kunaka electrode.
