Sei ma capacitor achiwanzokundikana?

Ma capacitor emagetsi ealuminiumchinhu chakakosha mumidziyo yakawanda yemagetsi uye chinoita basa guru mukuchengetedza nekuburitsa simba remagetsi. Zvisinei, pasinei nekukosha kwaro, ma capacitor anowanzo kundikana, zvichikonzera kutadza uye zvinogona kukuvadza sisitimu yese. Kunzwisisa zvikonzero zvekukundikana kwe capacitor kwakakosha pakuona kuvimbika uye kugara kwenguva refu kwemidziyo yemagetsi.

Pane zvikonzero zvakawanda nei ma capacitor achiwanzokundikana, chimwe chezvinonyanya kushandiswamacapacitor emagetsi earuminiyamuMa capacitor aya anoshandiswa zvakanyanya mumasekete nekuda kwe capacitance yawo yakakwira, mutengo wakaderera, uye voltage ratings yakakwira. Zvisinei, kana tichienzanisa nedzimwe mhando dze capacitor, ane hupenyu hushoma, izvo zvinogona kukonzera kutadza kushanda kwemidziyo yemagetsi kakawanda.

Chimwe chezvikonzero zvikuru zvinoita kuti macapacitor ealuminium electrolytic ashaye simba ndechekuti anonzwa kuchinja kwekushisa. Macapacitor aya anonzwa zvakanyanya kana tembiricha yachinja, uye kana tembiricha yakakwira inogona kukonzera kuti electrolyte iri mukati me capacitor iome, zvichikonzera kurasikirwa kwe capacitance uye kuwedzera kwe leakage current. Izvi zvinogona kukonzera kuti capacitor iome uye pakupedzisira ikundikane.

Chimwe chinhu chinokonzera kukundikana kwema capacitor e aluminium electrolytic itsika yavo yekudzikira nekufamba kwenguva. Ma electrolyte anoshandiswa muma capacitor aya anogona kukanganiswa nemakemikari, izvo zvinogona kukonzerwa nezvinhu zvakasiyana-siyana zvakaita sekupisa kwakanyanya kwekushanda, kushushikana kwevoltage, uye kusangana nezvinosvibisa zvakatipoteredza. Sezvo electrolyte ichidzikira, capacitance uye ESR (equivalent series resistance) ye capacitor zvinoshanduka, zvichikonzera kudzikira kwekushanda uye kuvimbika.

Pamusoro pekupisa nekukwegura, chimwe chikonzero chinoita kuti macapacitor ealuminium electrolytic anowanzo kundikana ndechekuti anogona kukanganiswa ne voltage surges uye ripple current. Ma capacitor aya anowanzo shandiswa muma power supply circuits uko anosangana ne high ripple currents uye voltage spikes. Nekufamba kwenguva, kudzokorora kushanduka kune high currents uye voltages kunogona kukonzera kuti zvikamu zvemukati zve capacitor zviderere, zvichikonzera kudzikira kwe capacitance uye kuwedzera ESR.

Pamusoro pezvo, dhizaini uye mhando yemacapacitor emagetsi earuminiyamuzvichakanganisawo kuvimbika kwavo uye mwero wekukundikana kwavo. Ma capacitor akachipa kana asina kuenzana anogona kushandisa zvinhu zvemhando yepamusoro uye maitiro ekugadzira, zvichikonzera mukana mukuru wekukundikana nekukurumidza. Kushandisa ma capacitor emhando yepamusoro, akaongororwa nemazvo mumidziyo yemagetsi kwakakosha kuderedza njodzi yekukundikana.

Kuti kuderedze njodzi yekukundikana kwecapacitor, zvakakosha kufunga nezvemamiriro ezvinhu nenzvimbo iyo capacitor ichashandiswa. Kutarisirwa kwakanaka kwekupisa, kuderedzwa kwevoltage, uye kusarudzwa kwakanyatsonaka kwemacapacitor zvichienderana nezvinodiwa uye kuyera kuvimbika kwawo zvinogona kubatsira kuwedzera hupenyu hwebasa rawo uye kuderedza njodzi yekukundikana.

Muchidimbu, macapacitor ealuminium electrolytic anowanzo kukonzera kutadza kushanda mumidziyo yemagetsi nekuda kwekunzwa kwavo tembiricha, kukwegura, kushushikana kwemagetsi, uye ripple current. Nekunzwisisa zvinhu izvi uye kutora matanho anodiwa, akadai sekusarudza macapacitor emhando yepamusoro uye kushandisa mamiriro akakodzera ekushanda, unogona kuderedza mukana wekuti capacitor isashande uye kuve nechokwadi chekuti michina yako yemagetsi yakavimbika.
