Le uthotho ukudityaniswa capacitors njengento capacitance ukhetho ukukhetha

Ekondensa - a amacandelo radio eqhelekileyo kakhulu, nto leyo ifumaneka onke amagama. It iqulathe ababhexeshi ezimbini ezahlulwe sisithuba a Heating (ngokuxhomekeke kuhlobo capacitors kusetyenziswa iindidi ezahlukahlukeneyo), ngamanye ngokoqobo lo zeesekethe, kodwa mthetho eziyintlanganisela kwi Heating. Uphawu ephambili nayiphi capacitor kukukwazi ukugcina isigxina - capacitance kunye ombane rated ngayo intlawulo umbane. Le capacitors electrolytic kufuneka polarities, kwaye luphawulwa obunamandla kwaye uluhlu olubanzi yombane, iphepha ukumelana uxinzelelo olukhulu, kodwa kufuneka encinane umthamo. Kukho kwakhona zizixhobo ezishiyanayo amandla, kodwa uhlobo ngalunye - sicelo yayo.

Ngokufuthi hams senze ingxaki kukhetho capacitors of capacitance okanye ombane. Iingcali bazi: kungekho ekunene, uyakwazi kuqokelela indibanisela izixhobo eziliqela, kuquka ibhetri. Xa ibhetri oludityanisiweyo akuvumelekanga, uqhagamshelwano parallel kunye uthotho capacitors.

Idibanisa izixhobo ngaxeshanye, kunokwenzeka ukuba kuzuzwe ukwanda komthamo. Jikelele kule battery iya kulingana udibaniso lwamaxabiso wonke capacitances (Ceq. = C1 + C2 + ...), lo ombane kwi isiqalelo ngasinye iya kulingana. Oku kuthetha ukuba ombane ezizezona zisezantsi capacitor, xa ambaxa na isicelo, ke ubuninzi lonke ibhetri.

Series uqhagamshelo of capacitors ezisetyenziswa kwimeko apho kuyimfuneko ukwandisa ombane ukuze zimelane zombane okanye ukunciphisa amandla abo. Kule ngobuwena, izinto ezidibene ngolu hlobo lulandelayo: qala enye ekupheleni komnye, oko kukuthi 'dibanisa' a 'thabatha' enye. Igunya capacitor elingana kule meko ibalwa le fomyula ilandelayo :. 1 / Ceq = 1 / C1 + 1 / C2 + ... Ukusuka ngalo, ukuba capacitors ezimbini Ceq = C1 * C2 / (C1 + C2), kwaye ke ngoko, amandla ibhetri iya kuba ngaphantsi kwe umthamo omncinane, ezisetyenziswa kuyo.

bank Capacitor kudla inika zidityanisiwe (exutyiweyo)
Connect. Ukubala capacitance esi sixhobo apho parallel enokusebenziseka uqhagamshelo uthotho capacitors, beesekethe lwaphulwa macandelo, ngokulandelelana kubalwa izakhono ngamnye kubo. Ngoko ke, lo capacitance C12 ubalwe = C1 + C2, ngoko Ceq = C12 * C3 / (C3 + C12).

Ngokusekwa iibhanki capacitor kunye sisimo ezahlukeneyo kunye namalungiselelo
uqhagamshelwano, uyakwazi ukufumana naluphi na umthamo nayiphi ombane anomdla. Series connection ka capacitors, kwakunye zidityanisiwe, esetyenziswa ezininzi iisekethe engahlawulwayo esele zenziwe. Kule meko kufuneka ithathele ingqalelo into yokuba capacitor ngamnye ngamnye i parameter ebaluleke kakhulu - le ukuvuza ngoku, oko unbalance ombane ngokunxulumene ezinxuseneyo kunye capacitance in series. Kubaluleke kakhulu ukuba ukhethe luvukelo shunt efunekayo.

Xa sisebenza kunye capacitors nangezinto zobuchwepheshe, musa ukulibala malunga nemigaqo yokhuseleko kunye nokoyikiswa ugesi.
