Mitundu ya ma capacitors: ubwino ndi kuipa

Chojambulira ndi chipangizo chamagetsi chimene chimakulolani kuti muzitha kusonkhanitsa ndikupatsanso mphamvu yamagetsi. Makhalidwe apamwamba a chinthucho ndi mphamvu yake, yomwe imatsimikizira kudalira kwa chiwongolero pamagetsi.

Chiwerengero cha ma capacitors

Njira zamakono zothandizira zipangizo zimalola kupanga mitundu yosiyanasiyana ya zipangizo. Omwe amanyamula mowa amaphatikizapo mankhwala omwe dielectric ndi mpweya. Ubwino wa mtundu uwu wa chipangizo ndizovuta kupanga. Zimapangidwira makina opanga mphamvu ndipo zimapangidwira makina osinthika. Zoipa za mtundu uwu wa chipangizo zimaphatikizapo kusakhazikika, kudalirika, kudalira pa chinyezi ndi kutentha kwa sing'anga, kukula kwakukulu, mphamvu zamagetsi zochepa, zomwe zimachepa pakati pa platinamu ya mpweya, komanso mphamvu yochepa.

Pali mapepala a mapuloteni, omwe pepala lopangidwa ndi dielectric lomwe limaphatikizidwa ndi transformer mafuta amachita. Zipangizozi zimakhala ndi zodalirika kwambiri komanso mphamvu zamagetsi. Pa mpweya wapamwamba amakhala ndi mphamvu zokwanira komanso zotsika zamakono.

Ambiri opangira mphamvu zamagetsi amapanga pamapepala. Pa izi, mbale ziwiri zimaphatikizidwa pamodzi, pakati pa pepala. Chipangizocho chimakulungidwa ndikuikidwa mu mtsuko wodzaza ndi mafuta otembenuza ndikusindikizidwa. Kuipa kwa chipangizochi kumaphatikizapo kulemera kwakukulu, kutengeka kwakukulu komanso kukana.

Mitundu ya electrolytic yamagetsi imakhala ndi dielectric, yomwe imaimira mawonekedwe a okusayidi, omwe amapezeka pamwamba pa zitsulo zogwira ntchito (nthawi zambiri aluminium). Chipangizocho chimapangidwa ndi kuyika mu tepi yotchedwa electrolyte tepi yokhala ndi zitsulo zokhazikika, pomwe filimu ya oxide yamphamvu imapangidwira, zomwe zimapangitsa kuthetsa chitsulocho.

Mbali yaikulu ya mitundu ya electrolytic ya capacitors ndi kukhalapo kwa polarity, pa mtengo umodzi womwe amachititsa kuti mapangidwe apanikitsidwe, ndipo pamene amasintha msanga iwo amawonongedwa. Izi zimachitika chifukwa cha mankhwala omwe amapanga pakati pa electrolyte ndi chitsulo cha mbale. Mafilimu a okusayidi amathyola pang'onopang'ono.

Komabe, ngati poizoniyo ikuwonekera, microcracks imangowonjezereka ndi okusayidi yatsopano. Ubwino wa zipangizozi zikuphatikizapo kuchuluka kwamtundu, kuipa - polarity, kutayika kwa katundu, kutayirira kovala, kutengeka kwakukulu kwa mkati.

Mitundu ya ma capacitors ndi ntchito yawo

Palinso makina omwe mica imakhala ngati dielectric, imagwiritsidwa ntchito pamagetsi osiyanasiyana. Popeza mica ili ndi mphamvu yokhala ndi mphamvu, izi zimakhala ndi mphamvu zamagetsi komanso mphamvu zamagetsi. Zowonongeka zimaphatikizapo kusakhazikika kwa magawo, osalumikizana, mtengo wapatali ndi kudalira mphamvu pa mphamvu yamakono.

Kuwonjezera pamenepo, mitundu yowonjezera, mafilimu, teflon, polypropylene ndi zipangizo zina zakhala zikugwiritsidwa ntchito.
