He aha mea he mea pihana, a me ka mea ia ia no

Wehewehe ana ia i ka mea pihana, e ike kakou i maopopo ka physical kumu o ka hana a me ka 'ole o ka paʻa mau hehee ai o kela oi a emi nui o ka uila hoʻoluku.

Condenser - mea he hehee ai o ka uila kaapuni, iloko olaila o nā lawelawe papa, kela mea keia mea o ka i maupaʻa ku pono hoailona uila kauoha. Papa kaawale ma ka insulator, a kokua ia lakou, e malama i ke kauoha.

He nui na ano o ka'īpale mea hoʻohana ma capacitors, me pālolo, Mika, tantalum a me ka polystyrene. Hoʻomano hoʻohana 'ia i loko o ka hana ana o capacitors a me na insulators me lewa, pepa a me ka ea. Kēlā me kēia no kēia mau mea ka pono ua ālai 'ka mea pihana papa mai ka hui' ana me kekahi i kekahi.

He aha mea he mea pihana?

Ke kau "mea pihana" characterizes kona hiki e hoahu pila nui kauoha. Ke pa alima o ka capacitance o Farad.

Inā ka mea pihana hale kūʻai kauoha aku 1 lei'ā'ī ma kekahi ikehu likeʻole ma waena o kona papa 1 volt, a laila ka mea, i ka 'auhau waiwai o kekahi farad. I mea, keia pa alima mea, ua nui no ka loa he mea hiki noi. Typical capacitance waiwai Hawaiʻi ka hoʻohana capacitors hāʻule i loko o ka papa koa milifarad (10.3 F) microfarads (10-6 F) a me picofarads (10-12 F).

He aha e na capacitors?

No ka maopopo i ka mea a ka mea pihana, ia mea pono, e noonoo i ke kumu o ke ano o keia ke keʻena, ke kaumaha ma muli o ka manao, olelo o ka palapala noi a me ka 'ano o ka dielectric.

e hoʻohana 'ia Electrolytic capacitors ma i puhi ai kahi kiʻekiʻe nona iho ua koi' ia. Ka hapa nui o kēia mau kumu mua i Polar. ʻike mau mea no ia - a tantalum Aluminum. Aluminum Electrolytic capacitors i nui ho'ēmi a ma nā kaiāulu i hoʻohana. Eia naʻe, tantalum i ke kūpono kou oi aku volumetric ka hoʻokōʻana a me ka i maikai loa pou ano.

Tantalum capacitors i like me ka dielectric o tantalum'okesaside. High pono, maikai alapine (frequency) ano, he ākea huahelu o ke hoʻohana mahana. Ka mea, e hoʻomano hoʻohana ma ka lolouila lako a pan ma ke kiʻekiʻe kiʻekiʻe o ka nona iho ma liʻiliʻi Ana. No ka mea, o kona pono i hua mai i ka nui mea no ka pono o ka uila no hana.

Ke keakea o tantalum capacitors hiki e wahi ana i ka pā lonoaʻili o ka lāʻau ikiʻai wale-he a ma-anakahi uila, a me na hoahanau kiʻekiʻe lilo o kēia mau huahana.

Power capacitors i kāu hoʻohana ma kiʻekiʻe anakahi uila nenoai. Ka mea, e hoʻomano hoʻohana e compensate no ka poho ma ka mana laina, a me ka hoʻoikaika 'ana i ka mana i loko o nā kumumea hanalima nā mea hoʻonoho. I ke kiʻekiʻe-metallized polypropylene ho film me ka hoʻohana 'ana o kūikawā ole-ʻawahia impregnation me hō'īpale kaʻaila.

Hiki i ka pakiko-destruct hiʻona na nā palapū, i haawi mai ia hou ka maluhia a me ka maoli i ka hana ke ola.

Pālolo capacitors i dielectric nā like pālolo. Ka mea, i wehewehe aku e kiʻekiʻe functionality o ka pae'ōnaehana anakahi uila, pono, haahaa poino a me ka haahaa kāki.

I ka laulā o ko lākou nā pihana'ū HEN, mai kekahi mau picofarads no ma kahi o 0,1 microfarads. He mea a ianoiyuaa a o ka loa hoʻomano hoʻohana ano o capacitors hoʻohana i ka uila lako a pan.

Kala Mika capacitors auou caiaiai laha mua Mika hehee wale. Ua he kiʻekiʻe kumupaʻa, he hermetic hale noho, a me ka nui nona iho no pa alima ka leo.

Laha ana o ke kala-Mika capacitors ua ālai 'ia kŘpa a pipiʻi.

I ka pepa a me ka metallized mea pihana'ūholo uila i o ka lahilahi Aluminum pepa kini, e like me ka dielectric, he kūikawā pepa impregnated paa (i kiʻi i hoʻoheʻeheʻe) a me ke kinowai ai dielectric. Ka mea, i hoʻohana 'ia i loko o haʻahaʻa-alapine (frequency) Radio wahi i puhi ai ma kiʻekiʻe paialewa. Ka mea, e kŘpa a nike.

No ke aha la i ka nele i ka mea pihana

Aia nō i ka helu o examples o ka hoʻohana 'ana o capacitors ma ka laulā likeʻole ma o ka hana. Ma kekahi, ka mea e hoʻomano hoʻohana 'ia no ka papaa o Analog lepa a me kikohoʻeo a me kaʻikepili. e hoʻohana 'ia ee iaaanu aey capacitors ma kele'ōlelo no ka alapine (frequency) hoʻoponopono a me ka AUOO o ke kelekaʻaʻike lako a pan.

A typical mamuli o ko lakou mau palapala noi i ka hoʻohana 'ana o ka mana kumu. Aia, i kēia mau kumu hana i ka hana o ka smoothing (kānana) o ka rectified anakahi uila ma ka auoiaea o kēia mau manaʻo. Ka mea, e hoʻohana 'ia e kekahi i loko o ke anakahi uila multipliers no ka hoʻomakaʻia kiʻekiʻe anakahi uila, nui loa kekahi mau manawa o ka hoʻokomo o anakahi uila. Condensers e hoʻomano hoʻohana 'ia ma nāʻano likeʻole o ke anakahi uila converters, uninterruptible mana lako manaʻo no kamepiula' ē aʻe, etc.

Wehewehe ana ia i ka mea pihana, ua hiki ole ke olelo i keia hehee ai hiki no hoi e malama nei me he waihona maikaʻi o electrons. Eia naʻe, ma ka ike maopopo i kēia kuleana pili i kekahi hoʻokau 'aie i ka politika-maikaʻi' ano o ka hana hō'īpale dielectric. Naʻe, ka mea pihana i ka waiwai lōʻihi kupono e hoahu uila ikehu wā disconnected mai ke kauoha aku la i kaapuni, no laila ka mea, hiki ke hoʻohana i ka? Aiaiiuie mana kahi.

Manawa i kona kū hoʻokahi physical waiwai o kēia mau kumu mua i ai hoʻomano hoʻohana i ka uila a me ka uila hana, i keia la kākaʻikahi kekahi uila huahana 'aʻole helu' ia ma ka liʻiliʻi loa hoʻokahi ka ke keʻena no kekahi hana.

Summing mai, ua hiki ke olelo aku i ka mea pihana - mea he invaluable hapa o ka nuiʻano o ka uila a me ka pou manaʻo, me ka a ka mea, ina ua hiki hou holomua ma ka 'epekema a me ka' ike loea.

Ia ka leo o ka mea a ka mea pihana!
