A: Mai ɗaukar kaya mai “mount-mount” yana nufin fakitin tsakiya na capacitor wanda aka ɗora shi lafiya a kan ƙarfe ko tushen resin, sannan a ɗora shi a saman (SMT) ta hanyar kushin da ke kan tushe. Ingantaccen juriyar girgiza ya dogara ne akan: 1) tsarin tushe mai ƙarfi wanda ke rarraba matsin girgiza daga PCB zuwa ga tushe gaba ɗaya; 2) daidaita ma'aunin tsakiya na ciki don hana motsi na lantarki na ciki; da kuma 3) mahaɗin tukunya mai aiki mai ƙarfi don ƙara buffer da kuma shan kuzarin girgiza. Wannan ƙirar mai matakai uku tare ta cimma babban tsalle a cikin juriyar girgiza.
5. T: Waɗanne ƙalubale ne capacitors ke fuskanta a cikin direbobin famfon ruwa/famfon mai a cikin tsarin sarrafa zafi na mota (kamar zafin jiki mai yawa da babban ƙarfin ripple)? Ta yaya Yung-Ming ke magance waɗannan ƙalubalen?
A: Ana amfani da na'urorin capacitor a cikin injinan famfo/famfon mai don tacewa da kuma buffering na fitarwa na inverter, suna fuskantar manyan kwararar ripple da aka samar ta hanyar sauyawa mai yawa, yanayin zafi mai yawa na injin, da girgizar injin kanta. Kayayyakinmu, tare da ƙarfin ripple current mai girma, ƙimar zafin jiki mai girma na 105°C/125°C, da juriyar girgiza na 10-30g, za su iya aiki cikin kwanciyar hankali a cikin irin wannan yanayi mai tsauri, suna tabbatar da daidaito da amincin sarrafa injin.
6: T: A cikin tsarin da ke da matuƙar muhimmanci ga aminci kamar Tuƙi na Wutar Lantarki (EPS), menene yanayin gazawar capacitors? Ta yaya Yongming ke ƙara guje wa gazawar da ke iya haifar da mutuwa kamar gajerun da'irori da kuma buɗe da'irori?
A: A cikin EPS, gazawar capacitor (musamman gajerun da'irori) na iya haifar da gurguwar tsarin. Muna inganta aminci ta hanyar waɗannan hanyoyin: 1) Amfani da kayan aiki masu tsafta da kuma sarrafa tsari mai tsauri don rage ƙazanta na ciki; 2) Tsarin bawul mai hana fashewa (kodayake nau'in hawa saman ne, yana da tsarin rage matsin lamba a cikin tsarinsa); 3) Gwajin kwararar iska 100% da juriyar ƙarfin lantarki don kawar da gazawar farko. Bugu da ƙari, kyakkyawan juriyar girgizarsa kai tsaye yana hana karyewar ciki (da'irori masu buɗewa) ko gajerun da'irori da girgiza ke haifarwa.
7: T: A tsarin sarrafa tashi na jiragen sama masu ƙarancin tsayi, menene babban aikin capacitors? Ana amfani da su don tace wutar lantarki, adana makamashi, ko haɗa sigina?
A: Ana amfani da shi sosai a cikin da'irori na samar da wutar lantarki na kwamfutocin sarrafa jirgin sama da direbobin motocin servo, yana aiki a matsayin mai daidaita wutar lantarki, tacewa, da kuma mai samar da wutar lantarki ta bugun jini nan take. Tsarin sarrafa jirgin sama yana da buƙatu masu yawa sosai don tsarkake wutar lantarki da amsawa nan take; ingantaccen aikin capacitor yana da mahimmanci don tabbatar da daidaiton bayanai na firikwensin da amsawar servo cikin sauri.
