Ama-capacitor ezokuphepha adlala indima ebalulekile emishini ye-elekthronikhi futhi ikakhulukazi ahlukaniswe izigaba ezimbili: x capacitors kanye nama-capacitors y.Zombili lezi zinhlobo zama-capacitors ziwela esigabeni sama-capacitor okuphepha, ngomehluko omkhulu wokuba yindawo yokuxhumana nesicelo.I-X capacitor imvamisa ixhumeke phakathi kwezintambo ezibukhoma nezingathathi hlangothi, ngenkathi i-y capacitor ixhunyiwe phakathi kwezintambo ezibukhoma nezomhlabathi.Umsebenzi wabo oyinhloko ukuhlinzeka ukuhlunga okusebenzayo kwemodi ejwayelekile nokuphazanyiswa kweModi okuhlukile esihlungisweni sokuhlinzekwa kwamandla, ngaleyo ndlela kuthuthukise ukuqina nokuphepha kokunikezwa kwamandla.Ukuchazwa okuyisisekelo kwe-capacitor yezokuphepha ukuqinisekisa ukuthi akubekeli ukuphepha komuntu siqu ngisho nangemva kokwehluleka kwayo.Lokhu kubaluleke kakhulu ekwakhiweni nasekusetshenzisweni kwemikhiqizo ye-elekthronikhi.
Ukuqhubeka nokucwengisisa, ama-capacitos ezokuphepha ahlukaniswe izigaba ezahlukahlukene eziphansi ngokusekelwe kumazinga okuphepha.Ngokuya kwe-International Electrotechnical Commission IEC664 Standard, ama-X capacitors ahlukaniswe amabanga we-X1, X2 kanye ne-X3 ngokusho kwamandla aphezulu wePulse akwazi ukumelana.Lezi zilinganiso zibonisa ukusebenza kweCapacitor ngaphansi kwezimo ezahlukahlukene ze-overvoltage.Ngasikhathi sinye, abakwa-YACacacitors nabo bahlukaniswa baba ngamabanga we-Y1, Y2, Y3 kanye ne-Y4 asuselwa kuhlobo lwabo lokufakelwa kanye nohlu lwe-voltageOkusemqoka, amandla we-y capacitor kuvame ukukhawulelwa ekuqinisekiseni ukuthi i-volwage yamanje ethambekelekile kanye namandla kagesi kanye nomthelela ekuvumelaniseni nge-electromagnetic, ukuhambisana kwe-electromagnetic.
Kubaluleke kakhulu ukugcizelela ukuthi ngaphezu kokuhlangana nemiphefumulo ethile ye-voltate izidingo, ama-capacitors we-Y kumele abe nemishado eyanele yokuphepha ngokuya ngogesi nokusebenza.Lokhu ukuvikela ukwehla kwamandla noma umjikelezo omfushane ngaphansi kwezimo zemvelo ezinokhahlo ngokweqile, ngaleyo ndlela kuqinisekiswe ukuphepha komuntu.Isibonelo, ngokuya nge-GJB151 ejwayelekile, umthamo we-Y capacitor akufanele ube mkhulu kune-0.1UF.Ukwakheka okunjalo kanye nokucaciswa kufanele kuqinisekiswe ukusebenza kwe-voltage ukumelana kwe-capacitor, ngaleyo ndlela kuqinisekiswe ukuphepha kwabasebenzisi ngenkathi kuvikela umsebenzi wemishini.
Ama-capacitor ezokuphepha asetshenziswa kabanzi emikhiqizweni ehlukahlukene kagesi emphakathini wanamuhla, futhi ahlobene kakhulu nezimpilo zethu zansuku zonke.Ikhwalithi yemikhiqizo ithinta ngqo ikhwalithi yethu yempilo nokuphepha.Ngakho-ke, lapho ukhetha ama-capacitors okuphepha, kufanele sikhethe imikhiqizo yangempela ekhiqizwa abakhiqizi abajwayelekile futhi badlulise izitifiketi zokuphepha emazweni ahlukahlukene ukuqinisekisa ikhwalithi nokuphepha kokusetshenziswa.Ukuqonda kanye nokukhetha ama-capacitor okuphepha afanele kubalulekile kunoma yiliphi iphrojekthi ehilela imishini ye-elekthronikhi.Akuhlobene nokusebenza okujwayelekile kwemishini, kepha futhi nasekuphepheni komsebenzisi.
