Mbale capacitor ndi chipangizo ake

Awiri mbale lathyathyathya oyenerera kufanana ndi mzake ndi ankasiyana dielectric ndi, zimapanga lathyathyathya capacitor. Izi ndi nthumwi zosavuta capacitors, amene anapangidwa kuti kudzikundikira heteronymic mphamvu. Ngati mbale ndi kudziŵitsa mlandu wofanana mu ukulu koma ufalikire modulus, ndi mphamvu ya magetsi kumunda pakati ochititsa adzakhala kawiri. Mlandu chiŵerengero cha mmodzi wa akuwauza kuti voteji pakati pa mbale capacitor otchedwa mphamvu ya magetsi:

C = Q / U

Ngati dongosolo la mbale ndi zonse, ndi mphamvu ya magetsi ya capacitor ndi tinganene kuti mosalekeza ochititsa aliyense mlandu. Mu dongosolo lonse la mphamvu mayunitsi magetsi - Farad (F). Lathyathyathya capacitor ali voteji wofanana Uwerenge intensities opangidwa ochititsa (E ₁ + E ₂ ... + E _N ). Vekitala udzakwaniritsidwa. Mtengo wa mphamvu magetsi ndi mwachindunji njila kwa dera la mbale ndi inversely njila kwa mtunda therebetween. Izi zikutanthauza kuti, kuti kuonjezera capacitance magetsi a capacitor ndi, m'pofunika kuti mbale m'dera zikuluzikulu, pamene kuchepetsa mtunda wa pakati pawo. Malinga dielectric mbale capacitor kungakhale:

• Paper.
• Mica.
• Polystyrene.
• Ceramic.
• Air.

Mfundo chipangizo, tiyeni tione chitsanzo cha capacitor pepala. Paper ankachitira ndi paraffin ndi ntchito mu nkhani iyi, monga dielectric lapansi. Anaika dielectric pakati n'kupanga zojambulazo ziwiri zimene zimakhala akuwauza. Kapangidwe lonse anapinda, imene mfundo ndi anaikapo kwa kugwirizana kwa munthu dera magetsi. chitsanzo ichi aikidwa mu nyumba ceramic kapena zitsulo. Lathyathyathya mpweya capacitor ndi zipangizo zina woyang'anira yosungirako ndi dongosolo zofanana, monga sing'anga ntchito zipangizo dielectric, amene dzina lake polemekeza capacitor yokha. Pamene kuthetsa mavuto, imene m'pofunika kupeza zedi wosadziwika, musaiwale ntchito kuchuluka amakhala insulator - dielectric zonse a sing'anga.

wailesi amagwiritsa madzi ndi wouma mitundu ya capacitors. Phula capacitors ndi electrolytic njira, imene oxidized mbale zotayidwa aikidwa. Ndi mankhwala pa nkhani zitsulo. The electrolyte ndi njira asidi boric ndi ena osakaniza ena. Youma mtundu yosungirako popangidwa ndi lopinda n'kupanga atatu, zotayidwa wina ndi zina - chitsulo, ndi pakati pawo - wosanjikiza gauze impregnated ndi electrolyte viscous. Mpukutuwo aikidwa mu nkhani zotayidwa ndi kudzazidwa ndi phula. Mbale capacitor ali osiyanasiyana ntchito ndi mtengo wotsika. Mwatsoka, zitsanzo sadzakhala m'malo mabatire wathu chifukwa mphamvu ndege capacitor ndi laling'ono kwambiri, ndi mlandu mofulumira kwambiri, "zinawukhira". Iwo sali oyenera monga gwero la magetsi, koma iwo mwayi wina - pamene nawuza mwa dera otsika kukaniza yomweyo kupereka mphamvu kusungidwa.
