Kugira ngo usobanukirwe neza nimbaraga zo kurwanya imbere no gutambuka, ni ngombwa kumenya ko inzitizi zijyanye na AC (guhinduranya amashanyarazi), mugihe kurwanya imbere bifitanye isano na DC (umuyoboro utaziguye). Nuburyo butandukanye, kubara kwabo gukurikiza formula imwe, R = V / I, aho R irwanya imbere cyangwa impedance, V ni voltage, kandi nubu.
Kurwanya Imbere: Inzitizi kuri Electron itemba
Kurwanya imbere bituruka ku kugongana kwa electron hamwe na ionic ya kiyobora, guhindura ingufu z'amashanyarazi ubushyuhe. Tekereza kurwanywa imbere nkubwoko bwo guterana amagambo bubuza electron kugenda. Mugihe ibintu bisimburana byanyuze mubintu birwanya, bitanga imbaraga za voltage. Iri tonyanga riguma mucyiciro hamwe nubu, byerekana isano itaziguye hagati yimigezi irwanya imbere imbere.
Impedance: Igitekerezo Cyagutse gikubiyemo Kurwanya Imbere
Impedance yerekana ijambo ryuzuye rikubiyemo uburyo bwose bwo kurwanya imiyoboro ya electron. Ibi ntabwo bikubiyemo kurwanya imbere gusa, ahubwo harimo no kwitwara. Nigitekerezo kiboneka hose kiboneka mumirongo yose nibigize.
Nibyingenzi gutandukanya reaction na impedance. Imyitwarire yerekana cyane cyane opposition itangwa kuri AC ya inductors na capacator, ibintu bitandukanye muburyo bwa bateri zitandukanye. Ihindagurika rigaragara mubishushanyo bitandukanye nindangagaciro zamashanyarazi ziranga buri bwoko bwa bateri.
Kugaragaza impedance, dushobora guhindukirira moderi ya Randles. Iyi moderi, igaragara ku gishushanyo cya 1, ihuza R1, R2, hamwe na C. By'umwihariko, R1 igereranya imyigaragambyo y'imbere, mu gihe R2 ihuye n'ikibazo cyo kohereza amafaranga. Byongeye kandi, C yerekana ubushobozi bwa kabiri. Ikigaragara ni uko moderi ya Randles ikunze gukuramo reaction ya inductive, kuko ingaruka zayo kumikorere ya bateri, cyane cyane kuri frequency yo hasi, ni nto.
Igishushanyo 1: Randles moderi ya batiri ya aside irike
Kugereranya Kurwanya Imbere na Impedance
Kugirango ubisobanure, igereranya rirambuye ryurwanya rwimbere nimbogamizi ryerekanwe hepfo.

Icyitonderwa muri Batteri Imbere Kurwanya Kurwanya
Nkumuti utanga igisubizo kabuhariwe mugukurikirana no gucunga bateri zinyuma, DFUN yibanda ku gupima imbere ya bateri imbere ihuza ibikorwa byashyizweho ninganda, bikurura imbaraga mubikoresho byemewe nka Fluke cyangwa Hioki. Gukoresha uburyo busa nibi bikoresho, bizwiho ukuri no kwemerwa kwabakiriya benshi, twubahiriza ibipimo nka IEE1491-2012 na IEE1188.
IEE1491-2012 iratuyobora mugusobanukirwa kurwanya imbere imbere nkibintu bigenda neza, bisaba guhora dukurikirana kugirango tumenye gutandukana kuva kumurongo. Hagati aho, IEE1188 isanzwe ishyiraho urwego rwibikorwa, itanga inama ko niba kurwanya imbere birenze 20% byumurongo usanzwe, bateri igomba gufatwa nkuwasimbuwe cyangwa igakorerwa ukwezi kwimbitse no kwishyuza.
Tuvuye muri aya mahame, uburyo bwacu bwo gupima imbere imbere burimo gukurikiza bateri kumurongo uhoraho hamwe nubu, hanyuma bigakurikirwa na voltage sampling. Gutunganya gukurikiraho, harimo gukosora no kuyungurura binyuze mumuzunguruko wa amplifier ikora, bitanga igipimo nyacyo cyo kurwanya imbere. Igitangaje cyihuse, ubu buryo busanzwe burangirira muri milisegonda 100, burata intera ishimishije ya 1% kugeza 2%.
Mu gusoza, kumenya neza ibipimo byo kurwanya imbere bitanga kugenzura neza bateri, bigira uruhare mu kuramba. Aka gatabo kagamije gufasha abashobora kubona ko bigoye gutandukanya kurwanya imbere n’imbogamizi, byoroha gusobanukirwa neza n’imiterere y’amashanyarazi. Kubindi bisobanuro birambuye no kubyumva, urashobora gushakisha ibikoresho byiyongereye biva DFUN Tech.
