I loko o ka honua paʻakikī o ka ʻenekinia uila, he liʻiliʻi nā mea e like me ubiquitous a i ʻole koʻikoʻi e like me ka capacitor. Inā mākou e kūkākūkā ana i ka microscopic circuitry i loko o ke kelepona a i ʻole nā mea hoʻohuli mana nui e hoʻokele ana i kahi kaʻa uila, capacitor he kuleana koʻikoʻi. E like me ka mea hana o ka pololei mīkini hoʻomaʻemaʻe ʻenehana a me nā mea ʻāpana, ua ʻike mua wau i ka maikaʻi o ka a capacitor kuhikuhi i ka hilinaʻi o ka ʻōnaehana holoʻokoʻa. Hoʻomaopopo nā ʻenekinia e like me Marcus i ka ʻāpana kaʻa Kelemania he a capacitor ʻaʻole ia he mea kūʻai wale; he mea hana pololei i hana ʻia e hale kūʻai a hoʻokuʻu i ka ikehu me ka manawa kūpono. Hoʻopili kēia ʻatikala i nā mīkini, nā ʻano, a me nā noi koʻikoʻi o kēia mea nui Kālā Kūlana Electronic.
He aha ka Capacitor a pehea e hana ai?
I kāna pae kiʻekiʻe loa, a capacitor he mea kupaa Kālā Kūlana Electronic hale kūʻai ikehu uila. He nani maʻalahi ka hale: aia i loko elua papa conductive i hookaawaleia e kekahi mea hoʻokaʻawale i ʻike ʻia he a dielectric. ʻAʻole pili kēia mau papa, a i ʻole electrodes. Ke hoʻohui ʻia me a puna uila, ʻaʻole kahe ke au i ka capacitor ma ka manaʻo kuʻuna ma muli o ka hoʻokaʻawale.
Akā, ka capacitor hōʻiliʻili kālā. I ka manawa uila uila hoʻohana ʻia, hōʻiliʻili nā electrons ma hookahi papa, hana ana hoʻopiʻi hewa, oiai nalo ka papa e ae i na electrons, lilo ua hoʻopiʻi maikaʻiʻia. Hoʻokumu kēia i kahi kahua uila ma kela aoao o ka dielectric. ʻO kēia hiki ke hoʻopaʻa i ka uku e hiki ai i ka capacitor e hana ma ke ʻano he pākaukau no ka manawa lōʻihi, he kānana, a i ʻole he mea hana manawa i loko o kahi circiit. Hoʻopili ia me ka uila a me ke au e hoʻopaʻa i ke kahe ʻana o ka uila, e hōʻoia i ka loaʻa ʻana o nā ʻāpana o lalo i ka mana maʻemaʻe a paʻa.
Pehea e mālama ai ka Capacitor i ka ikehu i loko o kahi kahua uila?
ʻAʻole like me ka pākaukau, nāna e mālama i ka ikehu me ke kemika, a capacitor mālama i ka ikehu ma ke kino i loko o kahi kahua uila. I ka manawa a hoʻopiʻi ʻia ka capacitor, he ka nui o ka uku ($Q$) kūkulu ʻia ma luna o nā papa. Mālama ʻia ka ikehu ma ke kahua electrostatic i hana ʻia ma waena o ka ʻelua electrodes. ^. 'Ōlelo mea dielectric he kuleana koʻikoʻi ma ʻaneʻi; kū'ē ia i ke kahe ʻana o ke au me ke kākoʻo ʻana i nā laina electrostatic o ka ikaika.
Hāʻawi kēia mīkini i kahi capacitor i hoʻopiʻi a hoʻokuʻu hikiwawe loa. He mau hola paha ka lōʻihi o ka pākaukau hoʻouka hou, aka a capacitor hiki hoʻokuʻu kona holoʻokoʻa uku mālama ʻia ma kahi hapa o ke kekona. He mea koʻikoʻi kēia waiwai no nā noi e koi ana i ka poha koke ʻana o ka mana, e like me nā uila uila a i ʻole nā laser pulsed. ʻO ka mālama ikehu hiki ke ho'ākāka 'ia e ka physical geometry o ka capacitor—o ka ili o ka uila nā papa a me ka mamao ma waena o lākou.
He aha ka Capacitance a pehea e ana ʻia ai?
Ka manaʻo oia ke ana o a capacitor'hiki ke hiki hale kūʻai he uku uila no ka wae o uila uila. Ua ana ia ma farads (F), i kapa ʻia ma hope o Michael Faraday. Eia naʻe, he nui ka nui o ka Farad hoʻokahi capacitance. Ma kahi capacitor hana, pili mākou i nā microfarads (µF), nanofarads (nF), a i ʻole picofarads (pF).
'Ōlelo waiwai capacitance Hoʻoholo ʻia e nā kumu nui ʻekolu: ka ʻili o nā papa conductive, ka mamao ma waena o nā papa, a me ka ʻae ʻia o ka dielectric.
$$C = \frac{\epsilon A}{d}$$
Aia ma kahi o $C$ capacitance, ʻo $\epsilon$ ka ʻae, ʻo $A$ ka ʻāpana, a ʻo $d$ ka mamao. Koho nā ʻenekinia i kahi capacitor ma muli o ka pono kaha kaha no kā lākou kikoʻī circiit. ^. A kiʻekiʻe capacitance waiwai 'o ia ho'i ka mea hiki hale kūʻai ʻoi aku ka uku i hāʻawi ʻia uila uila.
He aha nā ʻano maʻamau o nā Capacitors i hoʻohana ʻia i kēia lā?
Hele mai nā Capacitors i nā ʻano like ʻole a me nā mea hana, kūpono kēlā me kēia no nā hana like ʻole. ʻO ka nā ʻano capacitors hoʻokaʻawale ʻia e kā lākou dielectric mea waiwai.
- ʻO nā mea hoʻoheheʻe keramika: ʻAʻole polarized kēia a hāʻawi i ke kūpaʻa kiʻekiʻe. Hoʻohana nui ʻia lākou ma Rf (ke alapine o ka lekiō) a me nā noi kumu nui. Nā capacitors seramika liʻiliʻi maʻamau a kūʻai ʻole.
- Electrolytic Capacitors: Kaulana no ko lakou kiʻekiʻe capacitance waiwai, ua polarized kēia mau mea (loaʻa iā lākou kahi alakaʻi maikaʻi a maikaʻi ʻole). Electrolytic Loaʻa pinepine ʻia nā capacitors ma lako mana no ka kānana ʻana i ka ripple haʻahaʻa.
- Nā mea hoʻopaʻa kiʻiʻoniʻoni: Hoʻohana kēia i nā kiʻiʻoniʻoni plastik (e like me ka polypropylene a i ʻole polyester) e like me ka dielectric. Uaʻikeʻia lākou no ka hilinaʻi a me ka haʻahaʻa haʻahaʻa. Hoʻolako pinepine mākou i ka mīkini wiliwili no nā capacitors kiʻiʻoniʻoni metala i nā mea hana e koi ana i ka pololei i kēia mau mea.
- ʻO nā mea mana nui: Hoʻopili kēia i ka ʻokoʻa ma waena o nā capacitors a me nā pākaukau, hāʻawi nui hiki ke mālama no nā ʻōnaehana mālama ikehu.
No ke aha he mea koʻikoʻi ka Dielectric Material?
'Ōlelo dielectric ka puuwai o ka capacitor. ʻO ia ka mea non-conductive hoʻokaʻawale ʻia e kahi insulator ma waena o nā papa. ʻO ke koho o dielectric e hoʻoholo i ka helu uila, paʻa wela, a capacitance.
Inā ka Volta ma luna o ka capacitor lilo i kiekie loa, ka dielectric hiki ke wāwahi i lalo, e ʻae ana i ke au i ke arc ma waena o nā papa, e luku ana i ka ʻāpana. ʻO nā mea e like me ka ceramic a me ka kiʻiʻoniʻoni plastik he insulators maikaʻi loa. In nā capacitors electrolytic, o ka dielectric he ʻāpana lahilahi loa o ka oxide i ulu ʻia ma luna o ka pepa anode. ʻO ka lahilahi o kēia papa e hiki ai ke kiʻekiʻe capacitance, akā, e kaupalena ana i ka volta. I ka hana kiʻekiʻe-pololei, e hōʻoia ana i ka pono o ka mea dielectric i ka wā o ka wili ʻana he mea nui. Hiki i nā hemahema ke alakaʻi i ka hāʻule mua.
Pehea nā Capacitors kānana a hoʻopaʻa i nā lako mana?
In lako mana, o ka capacitor hana ma ke ano he waihona no hoʻopaʻa 'ōlelo hāʻawi uila. I ka hoʻololi ʻana i ka AC i DC, ʻo ka puka mai ka rectifier he pulsating Voli uila DC. No ka hoʻomaʻamaʻa ʻana i kēia, kahi nui capacitor ua kau like ia me ka puka.
I ka piʻi ʻana o ka voltage, ʻo ka hoʻopiʻi ʻia ka capacitor, mālama i ka ikehu. Ke hāʻule ka volta mai ka rectifier ma waena o nā piko, ʻo ka capacitor hoʻokuʻus kona ikehu malama hou i loko o ka circiit, hoopiha ana i na hakahaka. Hoʻemi kēia i ka "ripple" a hāʻawi i kahi puka DC paʻa. Nā capacitors electrolytic hoʻohana mau ʻia ma ʻaneʻi ma muli o ko lākou hiki ke hale kūʻai ka nui o ka ikehu. Me ka ʻole o lākou, sensitive Kālā Kūlana Electronics e hoʻopili ʻia i ka hoʻololi ʻana i ka uila.
He aha ke kuleana o ka hui ʻana a me ka wehe ʻana i nā kaapuni?
In kaapuni uila, hana nā capacitors i ʻelua mau hana ʻokoʻa akā like koʻikoʻi: hoʻopili ʻana a me ka wehe ʻana.
- Nā Capacitors Hui: Hoʻohana ʻia kēia no ka hoʻohui ʻana i ʻelua mau ʻanuʻu o kahi amplifier. A capacitor poloka DC i kēia manawa akā ʻae i nā hōʻailona AC (e like me nā leo a i ʻole nā hawewe lekiō) e hele. ʻAe kēia i ka hōʻailona AC e neʻe mai kahi pae a hiki i ka wā e hoʻokaʻawale ana i nā hoʻonohonoho bias DC o kēlā me kēia pae.
- Nā Capacitors hoʻokaʻawale: ʻIke ʻia hoʻi he capacitors bypass, hoʻohana ʻia kēia e wehe makemake ole DC ka walaʻau a i ʻole nā pihi alapine kiʻekiʻe mai nā laina mana. Hāʻawi lākou i kahi haʻahaʻa impedance ala i ka honua no ka walaʻau kiʻekiʻe, hoʻomaʻemaʻe maikaʻi i ka mana a hiki i kahi microchip. Nā capacitors hoʻokaʻawale hana ma ke ʻano he mālama ikehu kūloko, e hāʻawi ana i ka manawa koke i ka wā e hoʻololi ai kahi pahu kikohoʻe, e pale ana uila uila luu.
Pehea e hoʻohana ʻia ai nā Capacitors i nā kaʻa kaʻa kiʻekiʻe?
Ma ke aupuni o nā kaʻa uila (EVs) a me ka automation ʻoihana, pāʻani nā capacitors he kuleana koʻikoʻi ma kaʻa kaʻa a me nā mea hoʻohuli. ʻO ka loulou DC capacitor he ʻāpana nui e noho ana ma waena o ka pākaukau (DC) a me ka mea hoʻohuli (ʻo ia ka mea e hana ai i ka AC no ke kaʻa).
Pono kēia mau capacitors e mālama ke au kiʻekiʻe a wikiwiki hoʻopiʻi a hoʻokuʻu nā pōʻaiapuni. Hoʻopaʻa lākou i ka volta kaʻa kaʻa DC a hoʻopaʻa i ka ikehu regenerative e hoʻi mai ana mai ke kaʻa i ka wā o ka braking. Nā kaha kiʻiʻoniʻoni ʻoi aku ka maikaʻi ma ʻaneʻi no ka mea hiki iā lākou ke mālama i nā volta kiʻekiʻe a lōʻihi ke ola hana. Hana mākou i nā lako kikoʻī, e like me ka CBB665 CAPACITOR BRINCH, e hana i nā capacitors ikaika e pono ai no kēia hana kiʻekiʻe nā noi.
Pehea e pili ai ka hana pono ʻana i ka hilinaʻi Capacitor?
ʻO ka hilinaʻi o a capacitor hoʻomaka me ka hana ʻana. ʻO ka hapa nui o nā capacitors hana kiʻekiʻe, ʻoi aku ke kiʻiʻoniʻoni a me nā ʻano electrolytic, i hana ʻia e nā ʻāpana wili o conductive electrodes a dielectric mea a puni kekahi kumu. ʻO kēia kahi e pono ai ka ʻenehana pololei.
Inā ʻoluʻolu loa ka wili, hiki i nā papa ke haʻalulu, e hoʻoulu ai i ke koʻikoʻi mechanical a me ka capacitance drift. Inā ʻaʻole kūlike ka haʻalulu, ʻo ka dielectric hiki ke wrinkle a hāʻule. Ma Dongxin, hāʻawi mākou i nā ʻāpana e like me ka ʻO nā mea paʻa mandrel maʻamau no ka mīkini catacitist a iʻole ka mīkini uila e hōʻoia i ka paʻa pono o ke kumu i ka wā o ka wili. ʻO ka wili pololei e hōʻoia i ka nā papa i hoʻokaʻawale ʻia e kahi dielectric mālama i kahi mamao mau, e hōʻoiaʻiʻo ana i kahi paʻa waiwai capacitance a me ke ola lawelawe lōʻihi.
He aha nā mea e hoʻoholo ai i ka helu Voltage a me ka palekana?
Iloko capacitor he helu uila, ʻo ia ka ʻoi loa o ka hoʻomau uila uila hiki ke hoʻohana ʻia ma luna o ia me ka hemahema. ʻO ka ʻoi aku o kēia helu helu hiki ke kumu i ka dielectric e oki, e alakai ana i ke kaapuni pokole.
ʻO ka palekana kekahi hana o ka ʻano capacitor. No ka laʻana, electrolytic Hiki ke pahū nā capacitors inā ka uila uila hoʻohuli ʻia ka polarity (hoʻopili i ka maikaʻi i ka ʻino). Nā kaha kiʻiʻoniʻoni 'o ia ho'i, 'o ia ho'i, inā he ha'iha'i li'ili'i, 'o ia ka metala uila vaporizes a puni ka hewa, hoʻokaʻawale iā ia a ʻae i ka capacitor e hoʻomau i ka hana. Pono ka hoʻomaopopo ʻana i kēia mau palena palekana i ka hoʻolālā ʻana kaapuni mana Oole hoʻoponopono kumu mana ʻāpana.
