Ama-Film capacitor azacile ayingxenye ehlolwa kabanzi kumasekethe kagesi futhi anezinzuzo zokuzinza okuphezulu nempilo ende. Ngokwezinhlobo ezahlukene zesekethe yohlelo lokusebenza, ama-capacitor amafilimu angahlukaniswa ngezigaba ezifana namasekethe e-DC namasekethe e-AC. Kumasekhethi e-DC, ama-filimi capacitor ayo asetshenziselwa ikakhulukazi imisebenzi efana nokucindezelwa, ukushelela, nokugcinwa kwamandla, kuyilapho kumasekethe e-AC, anesibopho esikhulu sokumisa ukuphazamiseka kwama-high-frequency, ukuthuthukisa isici samandla, kanye nokuqalisa izinjini. Ikakhulukazi ezinhlelweni zokushayela kwezimoto, ama-capacitor amafilimu anezici zokuzuza okuphezulu kanye nokumelana namazinga kagesi aphezulu, okuwenza abe igiya lokuqondisa ngesikhathi sokuqala nokusebenza kwemoto. Lesi sihloko sizogxila ekusetshenzisweni nasezinzuzweni zama-capacitor amafilimu e-metalized ekuqalisweni kwemoto.
01 Ukusetshenziswa kwama-capacitor efilimu eyinsimbi kumadrayivu ezimoto nokuxazulula izinkinga
Ezinhlelweni zokushayela kwezimoto, ama-capacitor amafilimu asetshenziswa ohlangothini lwe-DC kanye nohlangothi lwe-AC ngokulandelana, ukuxazulula izinkinga eziningi.
| Isicelo se-DC side film capacitor: | |
| Umsebenzi | Imiphumela kanye nezinzuzo |
| Ukushintshashintsha kwe-voltage ebushelelezi | Gwema ukwehluleka kwesistimu yokushayela ngenxa yokungaqini kwamandla kagesi |
| Ukunikezwa kwamandla okuzinzile | Qinisekisa ukuthi i-motor drive system isebenza ngokujwayelekile endaweni ene-voltage ezinzile |
| Isicelo se-AC side film capacitor: | |
| Umsebenzi | Imiphumela kanye nezinzuzo |
| Amandla okuhlunga kanye nesinxephezelo | Thuthukisa ukusebenza kahle kokuqalisa i-motor, wehlise i-inrush current ngesikhathi sokuqala, futhi unciphise umthwalo wokuqalisa |
| Yehlisa umsindo nokudlidliza | Thuthukisa ukuzinza kokusebenza kwemoto futhi uqinisekise ukusebenza kahle kwemoto |
| Thuthukisa isici samandla | Yehlisa ukulahleka kwamandla futhi uthuthukise ukusebenza kahle sekukonke |
02 Ukuqhathaniswa kwama-capacitor efilimu enziwe ngensimbi nama-aluminium electrolytic capacitor
Ama-capacitor efilimu anensimbi anezinzuzo ezisobala ngaphezu kwama-aluminium electrolytic capacitor ngokuya nge-voltage ukumelana. Ama-capacitor efilimu enziwe ngensimbi ngokuvamile ane-voltage ephezulu yokumelana futhi angasebenza ngokuzinza ezindaweni ezinokhahlo. Ngokuphambene, ama-aluminium electrolytic capacitor ane-voltage ephansi yokumelana, anciphisa ukusetshenziswa kwawo kwezinye izinhlelo zokusebenza ezinamandla kagesi. Ngakho-ke, ama-capacitor amafilimu e-metalized afaneleka kakhulu kumasistimu okushayela kwezimoto ezinama-voltage aphezulu kanye nezidingo zokuzinza okuphezulu.
03 YMIN izincomo zokukhetha i-capacitor yefilimu eyenziwe ngensimbi
Uchungechunge lwe-MAP kanye nochungechunge lwe-MDP lwe-metalized film capacitor oluqaliswe nguYMINAma-elekthronikhi aklanyelwe ngokukhethekile amasistimu okushayela imoto ukuze ahlangabezane nezidingo zezimo ezihlukahlukene zokusebenza eziyinkimbinkimbi.

04 Fingqa
Njengoba ubuchwepheshe bezimoto buthuthukela ekusebenzeni kahle okuphezulu, ukonga amandla kanye nobuhlakani, ukuthuthukisa ukusebenza kahle kokuqala kanye nokuthembeka kokusebenza sekube yinhloso ebalulekile. Ama-capacitor amafilimu anensimbi adlala indima ebalulekile ezinhlelweni zokushayela kwezimoto ngenxa yokusebenza kwawo okuhle kakhulu.YMINUchungechunge lwe-MAP ye-MAP kanye nama-capacitor amafilimu ochungechunge lwe-MDP, anevoltheji yawo ephezulu yokumelana, i-ESR ephansi nempilo ende, ahlinzeka ngezixazululo ezisebenzayo zemishini yezimoto emkhakheni wezimboni kanye nabathengi. Ngokuzayo, ngokuthuthuka okusheshayo kobuchwepheshe obusha bamandla kanye nokukhiqizwa okuhlakaniphile, ama-capacitor amafilimu ensimbi azothuthukisa ukusebenza kwawo ukuze afinyelele izinga eliphezulu lamanje, impilo ende kanye nokusetshenziswa kwamandla okuphansi, ukusiza amasistimu okushayela kwezimoto afinyelele emazingeni aphezulu. izinga.
