A jerin dangane da capacitors a matsayin wani zaɓi selection capacitance

Condenser - mai matukar kowa rediyo aka gyara, wadda ake samu a duk Concepts. Ya kunshi biyu conductors rabu da wani dielectric (dangane da irin capacitors amfani da daban-daban iri), Ina nufin jiki da wannan rangadi, amma cajin za a iya tara a dielectric. Babban halayyar wani capacitor ne ikon adana cajin - capacitance da kuma kimanta irin ƙarfin lantarki na lantarki cajin. A electrolytic capacitors da polarities, kuma an halin da manyan iya aiki da kuma fadi da kewayon voltages, takarda gagara girma danniya, amma da kananan iya aiki. Akwai kuma na'urori tare da sãɓãwar launukansa iya aiki, amma kowane irin - da aikace-aikace.

Sau da yawa hams fuskanci matsalar selection na capacitors na capacitance ko ƙarfin lantarki. Ma'aikata sani: in babu dama, za ka iya tattara wani hade da dama kida, ciki har da baturi. A hada baturin da aka yarda, da layi daya da kuma jerin dangane da capacitors.

Haxawa da na'urorin a layi daya, shi ne zai yiwu a cimma wata karuwa a iya aiki. Janar a cikin wannan baturi zai zama daidai da Naira Miliyan Xari da duk capacitances (Ceq. = C1 + C2 + ...), da irin ƙarfin lantarki a kowane kashi zai zama daidai. Wannan yana nufin cewa mafi ƙarancin irin ƙarfin lantarki na capacitor, a fili da amfani, shi ne matsakaicin ga dukan baturi.

Series dangane da capacitors amfani da wani hali inda ya zama dole mu ƙara ƙarfin lantarki cewa zai iya tsayayya da kayan ko rage iya aiki. A wannan embodiment, abubuwa suna da alaka ne kamar haka: a fara da daya ƙarshen sauran, da cewa shi ne "da" zuwa "debe" wasu. Capacity m capacitor a wannan harka da aka lasafta ta da wadannan dabara :. 1 / Ceq = 1 / C1 + 1 / C2 + ... Daga wannan, da cewa biyu capacitors Ceq = C1 * C2 / (C1 + C2), sabili da haka, da damar baturi zai zama kasa da m iya aiki, a yi amfani da shi.

Capacitor banki sau da yawa samar da wani hade (Mixed)
Connect. Don lissafi da capacitance irin wannan na'urar a cikin abin da aiyuka a layi daya da kuma jerin dangane da capacitors, kewaye karya cikin sassan, sa'an nan jẽre lasafta damar kowane daga cikinsu. Saboda haka, lasafta capacitance C12 = C1 + C2, sa'an nan Ceq = C12 * C3 / (C3 + C12).

Ta hanyar kafa capacitor bankuna tare da daban-daban jeri kuma shirye-shirye
connection, za ka iya karba kowace iya aiki a kowane sha'awar irin ƙarfin lantarki. Series dangane da capacitors, kazalika da a hade, a yi amfani da yawa shirye-sanya mai son haihuwarka. A wannan yanayin da shi dole ne ya yi la'akari da cewa kowane capacitor yana da matukar muhimmanci mutum siga - da yayyo halin yanzu, shi zai iya unbalance ƙarfin lantarki a layi daya dangane da capacitance a jerin. Yana da matukar muhimmanci don zaɓar bukata shunt juriya.

Lokacin aiki tare da capacitors da kuma lantarki, kada ka manta game da dokoki na sirri tsaro da kuma barazanar da lantarki tura.
