Kugwirizana mndandanda wa capacitors ngati njira kusankha capacitance

Condenser - ndi zigawo sizachilendo wailesi, lomwe likupezeka mu mfundo zonse. Amakhala ndi ochititsa awiri olekanitsidwa ndi dielectric (malingana ndi mtundu wa capacitors ntchito mitundu zosiyanasiyana), i.e. thupi dera lino, koma woyang'anira akhoza atasunga dielectric lapansi. Khalidwe lalikulu la capacitor aliyense amatha kusunga mlandu - capacitance ndi oveteredwa voteji wa mtengo zamagetsi. The capacitors electrolytic ndi polarities, ndi yodziwika ndi mphamvu zazikulu ndi osiyanasiyana voltages, pepala kupirira mavuto aakulu, koma ndi mphamvu yaing'ono. Palinso zipangizo ndi kusinthasintha mphamvu, koma mtundu uliwonse - tanthauzo lake.

Nthawi zambiri hams akukumana ndi vuto la kusankha capacitors wa capacitance kapena voteji. Akatswiri kudziwa: pakalibe kumanja, mukhoza kusonkhanitsa osakaniza zida zingapo, kuphatikizapo batire la. Mu batire ophatikizana amaloledwa, kufanana ndi mndandanda kugwirizana capacitors.

Polumikiza zipangizo mu kufanana, n'zotheka kukwaniritsa kuwonjezeka mphamvu. General mu batire uyu adzakhala wofanana Uwerenge capacitances onse (Ceq. = C1 + C2 + ...), ndi voteji pa chilichonse mchitidwe adzakhala ofanana. Izi zikutanthauza kuti voteji osachepera capacitor, mu pawiri wa ntchito, ndi pazipita kwa batire lonse.

Series kugwirizana capacitors ntchito pa mlandu ndi kumene kuli kofunika kuonjezera voteji chimene chingathe kupirira zipangizo kapena kuchepetsa mphamvu zawo. Mu chimake izi, zinthu ogwirizana motere: kuyamba ndi kumalekezero a ena, kuti ndi "kuphatikiza" ndi "opanda" zina. Mphamvu ofanana capacitor Pankhaniyi kuchita masamu ndi chilinganizo zotsatirazi :. 1 / Ceq = 1 / C1 + 1 / C2 + ... Kuchokera mwa ichi, kuti capacitors awiri Ceq = C1 * C2 / (C1 + C2), choncho, mphamvu batire adzakhala zosakwana mphamvu zochepa, ntchito.

Capacitor banki zambiri amapereka ophatikizana (wosanganiza)
Lumikizani. Kuwerengetsa capacitance umenewu chipangizo chimene kufanana Akutsatira ndi mndandanda kugwirizana capacitors dera wosweka m'zigawo, ndiye successively masamu mphamvu ya aliyense wa iwo. Choncho, masamu capacitance C12 = C1 + C2, ndiye Ceq = C12 * C3 / (C3 + C12).

Kudzera kukhazikitsidwa kwa mabanki capacitor ndi masanjidwe osiyana ndi makonzedwe
kugwirizana, inu mukhoza kutenga mphamvu iliyonse kuti voteji aliyense chidwi. Series kugwirizana kwa capacitors, komanso zimagwira ntchito mu madera ambiri okonzeka zopangidwa ankachita masewera. Pankhaniyi ayenera kuganizira mfundo yakuti aliyense capacitor ali ofunika kwambiri munthu chizindikiro - ndi kutayikira masiku ano akhoza unbalance voteji mogwirizana kufanana ndi capacitance mu mndandanda. Nkofunika kusankha chofunika shunt kukana.

Pamene akugwira capacitors ndi zamagetsi, musaiwale za malamulo a wotetezedwa ndi kuopseza mantha magetsi.
