Aluminium electrolytic capacitors inogona kugara chero kubva kuzviuru zvishoma maawa kusvika kumakore akawanda, zvichienderana nekupisa, ripple current, voltage stress, capacitance, electrolyte quality, sealing design, uye nharaunda yekushanda. A capacitor yakarongerwa maawa e2,000 pa105 C hazvirevi kuti ichakundikana mushure memaawa e2,000 mukushandiswa kwakajairika. Zvinoreva kuti chikamu chinoedzwa kune iyo yakatemerwa hupenyu pasi pemamiriro ekunze ekupisa.
Mumidziyo chaiyo, kana iyo capacitor ichishanda pane yakaderera tembiricha uye mukati memiganhu yayo yemagetsi, hupenyu hwayo hwebasa hunogona kunge hwakareba. Ichi ndicho chikonzero mainjiniya nezvikwata zvekutenga zvinowanzo shanda pamwe chete aluminium electrolytic capacitor vagadziri kusarudza iyo chaiyo yakatevedzana, voltage rating, tembiricha chiyero, uye yehupenyu giredhi kune yega yega application.
Nei Hupenyu Hwose Iri Nyaya Yakakosha
Aluminium electrolytic capacitors anoshandiswa zvakanyanya mumagetsi emagetsi, madhiraivha e LED, inverters, majaja, madhiraivha emota, kudzora kwemaindasitiri, midziyo yekuteerera, midziyo yemumba, uye masystem emagetsi anovandudzwa. Iwo akakosheswa nehukuru capacitance, compact size, uye mutengo unoshanda.
Nekudaro, ivo vane electrolyte. Nekufamba kwenguva, kupisa uye kushushikana kwemagetsi kunogona kukonzera kurasikirwa kwe electrolyte, kuwedzera kwakaenzana kuteedzera kuramba, kuderedzwa capacitance, kuvuza ikozvino shanduko, uye pakupedzisira kutadza. Izvi zvinoita kuti kuronga kwehupenyu kunyanyokosha mumidziyo inotarisirwa kuti irambe ichimhanya.
Kunzwisisa Kwakarongwa Hupenyu hwose
Capacitor datasheets anowanzo nyora hupenyu hwese mumaawa pane yakanyanya tembiricha, senge:
- 1,000 maawa pa105 C
- 2,000 maawa pa105 C
- 5,000 maawa pa105 C
- 10,000 maawa pa105 C
Izvi hazvina kufanana nehupenyu chaihwo muchigadzirwa. A capacitor yakarongerwa maawa 5,000 pa105 C inogona kugara kureba kana ichishanda pa65 C, ine mwero ripple ikozvino uye yakakodzera mhepo.
Nguva yeupenyu yakayerwa ireferensi yebvunzo inodzorwa. Mainjiniya anoishandisa kuenzanisa chigadzirwa chakatevedzana uye fungidziro yehupenyu hwesevhisi pasi pemamiriro chaiwo.
Mutemo Wekupisa
Tembiricha ndicho chinhu chikuru chinokanganisa aluminium electrolytic capacitor hupenyu. Sezvo tembiricha inokwira, electrolyte inomesa kunze nekukurumidza uye kuchembera kwemakemikari emukati kunowedzera.
Mutemo wakajairwa weinjiniya ndewekuti hupenyu hwecapacitor hunogona kuita zvakapetwa kaviri kune yega yega 10 C kudzikiswa kwekushisa kwepakati, mukati memiganho inoshanda. Semuenzaniso, capacitor yakatarwa maawa 2 000 pa105 C inogona kugara kwenguva yakareba pa85 C, uye yakareba ichiri pa65 C.
Mutemo uyu ungori fungidziro. Hupenyu chaihwo hunotsamira pane capacitor dhizaini uye mamiriro ekushanda, asi inoratidza kuti nei kutonga kwemafuta kuchikosha zvakanyanya.
Ripple Current uye Kupisa
Ripple ikozvino inogadzira kupisa kwemukati mukati me capacitor. Kunyangwe kana mhepo yakatenderedza isiri kupisa zvakanyanya, yakakwira ripple ikozvino inogona kusimudza iyo capacitor yepakati tembiricha.
High ripple current inogona kutungamirira kune:
- Kukurumidza kubuda kwe electrolyte
- Kupisa kwepamusoro kwemukati
- Kuwedzera ESR
- Yakaderedzwa capacitance
- Hupenyu hupfupi hwebasa
- Zvinogoneka kubuda kana kutadza
Pakusarudza capacitor, mainjiniya anofanirwa kuenzanisa ripple yazvino chiyero nemamiriro chaiwo edunhu. Kuvimbika aluminium electrolytic capacitor vagadziri ipa ripple zvazvino zvinotsanangurwa kubatsira vagadziri kudzivirira kudzikisira.
Voltage Stress
Kushanda capacitor padhuze neiyo yakanyanya rated voltage kunogona kuwedzera kushushikana. Kushandisa yakakodzera voltage margin kunogona kuvandudza kuvimbika.
Semuenzaniso, dunhu rine 24V DC rinogona kushandisa capacitor yakayerwa pamusoro pe24V, zvichienderana nekuyerera, kuvhiya, tembiricha, uye chengetedzo margin. Mune yakakwirira-yakavimbika madhizaini, mainjiniya anodzivirira kushanda ma capacitor nguva dzose pamuganho wakakwana.
Nekudaro, kuwedzeredza voltage yakawandisa kunogona kukanganisa saizi, mutengo, uye dzimwe nguva kuita, saka kusarudzwa kunofanirwa kuve kwakadzikama.
Application Environment
Upenyu hweCapacitor zvakare hunoenderana nekuti chikamu chinoshandiswa kupi.
Power Supplies
Mukuchinja magetsi, ma capacitor anotarisana ne ripple current, kupisa kubva kuzvinhu zviri pedyo, uye kuenderera mberi kushanda. Kusarudzwa kwehupenyu hwose kwakakosha.
Vatyairi ve LED
Vatyairi ve LED vanowanzoiswa munzvimbo dzinopisa. Capacitor hupenyu hwese hunogona kukanganisa zvakananga kuvimbika kwemwenje.
Motor Drives uye Inverters
Aya masisitimu anogona kufumura ma capacitor kune ripple ikozvino, vibration, kupisa, uye voltage spikes.
Zvemotokari uye Zvekunze Electronics
Tembiricha yebhasikoro, humidity, vibration, uye nguva refu yekushanda inogona kupfupisa capacitor hupenyu kana chikamu chisiri chakasarudzwa.
Zviratidzo Zvekukwegura
Kuchembera aluminium electrolytic capacitors inogona kuratidza zviratidzo zvinooneka kana zvemagetsi.
Zviratidzo zvinogona kusanganisira:
- Bulging top vent
- Leakage
- Shrink sleeve discoloration
- Kuwedzera ESR
- Yakaderedzwa capacitance
- Simba remagetsi risina kugadzikana
- Noise kana ripple matambudziko

- Kushanda kwepakati
- Kukundikana kwakakwana kwedunhu
Hakusi kukundikana kwese kunoonekwa. Mamwe ma capacitor anosvibisa magetsi achitarisa zvakajairika kubva kunze.
Maitiro ekuwedzera Capacitor Hupenyu
Vagadziri uye vagadziri vemidziyo vanogona kuvandudza hupenyu nekudzora kushushikana.
Maitiro anobatsira anosanganisira:
- Sarudza yepamusoro-yakatemerwa hupenyu hwese.
- Chengetedza tembiricha yekushandisa yakaderera.
- Ipa kuyerera kwemhepo kana kupisa kunyura.
- Dzivisa kuisa capacitor pedyo nezvinopisa zvikamu.
- Shandisa zvakakodzera voltage margin.
- Sarudza yakaringana ripple current rating.
- Shandisa yakakodzera capacitance kukosha.
- Dzivisa kudedera kwakanyanyisa.
- Dzivirira kubva pakunyorova kana zvichidiwa.
- Tevera mirairo yekupisa tembiricha.
- Shanda nevashambadziri vanokwanisa.
Kurongeka kwakanaka uye dhizaini yekupisa inogona kuve yakakosha sekusarudza capacitor.
Chii Vatengi Vanofanira Kubvunza Vagadziri
Paunenge uchienzanisa vatengesi, bvunza:
- Ndeapi maresheni ehupenyu aripo?

Ndine ruzivo aluminium electrolytic capacitor vagadziri inogona kubatsira kuenzanisa capacitor series kune dunhu pane kungotora nhamba yechikamu.
Kuchengeta Hupenyu Hunokoshawo
Macapacitors anogona kukwegura mukuchengetedza, kunyanya kana akachengetwa kwemakore akawanda kana mukupisa kukuru. Kuchengetedza kwenguva refu kunogona kuwedzera kuvuza ikozvino kana kuda kugadziriswa kwemagetsi kusati kwashandiswa, zvichienderana nechigadzirwa uye nguva yekuchengetedza.
Vatengi vanofanirwa kuchengeta ma capacitor munzvimbo yakaoma, ine mwero-tembiricha uye vateedzere kurudziro yevashambadziri yehupenyu hwesherufu.
Mhedziso
Aluminium electrolytic capacitors inogona kugara kubva kuzviuru zvishoma zvakayerwa maawa kusvika kumakore mazhinji mumidziyo chaiyo. Hupenyu hwavo hunoenderana zvakanyanya netembiricha, ripple ikozvino, voltage stress, electrolyte mhando, chisimbiso dhizaini, uye dunhu redunhu.
A capacitor's datasheet yehupenyu hwese ireferensi yakaedzwa pasi pemamiriro ekunze ekupisa, kwete zuva rakareruka rekupera. Nekusarudza iyo chaiyo nhevedzano, kuderedza kupisa, kubvumira voltage uye ripple margin, uye kushanda nekuvimbika aluminium electrolytic capacitor vagadziri, mainjiniya anogona kuvandudza kuvimbika kwemidziyo uye kuderedza kutadza kwekutanga.
Kuti uwane ruzivo rwealuminium electrolytic capacitor chigadzirwa, shanya DGDX Electronics.
