Chip Chikhalidwe Chomwe Chimachita Choke | KHALANI BWINO

? Kodi pali yamawangamawanga kwa inductors wamba mode Zimenezi ziyenera zambiri makasitomala ndi ogula kukaikira The wamba modetsa nkhawa wopanga Getwell adzayankha wamba mode kutsamwa mapeto palibe chigamba;

Tiyenera kumvetsetsa momwe zimagwirira ntchito; Ma moductors omwe ali ndimayendedwe amakono amakhala ndi mwayi wokwanira, kuyimitsidwa kwakukulu ndikulowetsa m'minda yamagetsi, kuponderezedwa kwabwino, komanso kutayika kosasunthika kosiyanasiyana mosiyanasiyana.

Chizolowezi chofala chimakhala chofala kwambiri m'moyo watsiku ndi tsiku. Mukamagwiritsa ntchito makompyuta, pali ma circuits angapo othamanga, ma digito ndi ma analog omwe amasakanizidwa pa bolodi lamkati lamakompyuta. Akamagwira ntchito, amapanga mafunde ambiri amagetsi amagetsi ndipo amasokoneza wina ndi mzake, omwe ndi EMI. Kulowererapo kwamagetsi kumatulutsidwanso panja kudzera pa kondakitala kapena chingwe chakunja pa bolodi la amayi, kuchititsa kuipitsa mphamvu yamagetsi yamagetsi, sikuti kumangokhudza zachilendo ntchito ya zida zina zamagetsi, komanso zovulaza thupi.

Kodi pali zigamba zazomwe zimachitika modabwitsa?

Izi ndizofanana ndi kapangidwe kake komanso magwiridwe antchito amtundu wowongoka chifukwa cha chip chosakanikirana.

Makina omwe amagwiritsidwa ntchito mobwerezabwereza amakhala ndi ma conductor omwe amayenda mozungulira mozungulira machubu otetezera, omwe amalumikizana. Ma machubu otetezera amatha kukhala opanda dzenje kapena okhala ndi chitsulo pakati kapena maginito ufa, womwe umatchedwa inductance.In L, mayunitsiwo ndi Henry (H) ndi milliHenry

(mH), yaying'ono Henry (uH), 1H = 10 ^ 3mH = 10 ^ 6uH.

Kugawidwa kwamachitidwe amachitidwe wamba.

Ogawidwa ndi mawonekedwe a inductance: inductance yokhazikika, kusinthasintha kosiyanasiyana.

Ogawidwa malinga ndi kuthekera kwa maginito conductor: koyilo lopanda, koyilo la ferrite, koyilo wachitsulo, koyilo wamkuwa.

Wogulitsa ndi momwe ntchito imagwirira ntchito: koyilo ya antenna, koyilo yokhotakhota, kolola kotsamitsa, koyilo lokola, koyilo yopatutsa.

Okhazikitsidwa ndi kapangidwe kokhotakhota: koyilo yamodzi-umodzi, koyilo yamiyala yambiri, koyilo wa zisa.

Main magawo magawo a koyilo ya inductance:

1. Kuchepetsa L

Inductance L imayimira mawonekedwe amtundu wa coil wokha, osadalira kukula komwe kulipo pakadali pano Kupatula ma coil apadera a inductance (ma code inductors), inductance nthawi zambiri sichimadziwika pa coil, koma ndi dzina lenileni.

2. XL yopatsa chidwi

Kukula kwa coil inductance pa AC kutsekeka kwamakono kumatchedwa inductive reactance XL, unit ndi ohm. Ubale wake ndi inductance L komanso kusinthasintha kwapafupipafupi F ndi XL = 2πfL

Chikhalidwe cha Q

Quality factor Q ndi kuchuluka kwakuthupi komwe kumayimira mtundu wa koyilo, Q ndi chiŵerengero cha kukana kutulutsa XL ndi kukana kwake kofanana, ndiko kuti: Q = XL / R.

Kuchulukitsa kwa Q koyilo, ndikuchepa kocheperako. Mtengo wa koyilo wa Q ndikogwirizana ndi kukana kwa waya kwa DC, mafupa a dielectric, kutayika komwe kumachitika chifukwa cha chishango kapena chitsulo, komanso kukopa kwakhungu pafupipafupi. Mtengo wa Q wa koyilo nthawi zambiri umakhala pakati pa makumi mpaka mazana.

4.kugawidwa kwa capacitance

Kutha pakati pa koyilo kumatembenuka ndikusinthasintha, pakati pa koyilo ndi chishango, pakati pa koyilo ndi mbale kumatchedwa capacitance yogawidwa.Kukhalapo kwa magwiridwe antchito kumachepetsa mtengo wa koyiloyo ndikupangitsa kukhazikika kukuipiraipira. Chifukwa chake, zingwe zazing'ono zomwe zimagawidwa za coil zimakhala zabwino.

Makina omwe amagwiritsidwa ntchito kwambiri ndi awa:

1.Single wosanjikiza koyilo

Chingwe chimodzi chosanjikiza chimapangidwa ndi mabala olumikizidwa ndi waya kuzungulira ndi kuzungulira pa chubu cha pepala kapena chimango cha bakelite. Monga transistorized radio medium wave antenna coil.

2. koyilo wa zisa

Ngati koyilo idutsa, ndege zake sizifanana ndi kuzungulira, koma zimadutsana ndi Ngodya yotanthauzidwa ndi Yi. Izi zimatchedwa koyilo ya zisa. Ndipo kuchuluka kwa nthawi yomwe waya imapinda mmbuyo ndikubwerera ikazungulira kamodzi, nthawi zambiri amatchedwa kuchuluka kwa malo opindika. Njira iyi ili ndi ma voliyumu ang'onoang'ono, kutulutsa kocheperako pang'ono ndikulowetsa kwakukulu. zisa zovekera makina ntchito kuti mphepo coils mu zisa. Zowonjezera pamene zikulunga, ndizochepa zomwe zimagawidwa.

3.Ferrite pachimake ndi chitsulo ufa pakati koyilo

Kulowetsa kwa coil kumakhudzana ndi kupezeka kapena kupezeka kwa maginito oyikapo.Kulowetsa ferrite pachimake pakabowo kokhako kumatha kukulitsa kutha kwazinthu ndikusintha kolowera.

4.Copper koyilo

Koyilo yamkuwa yamkuwa imagwiritsidwa ntchito kwambiri pamafunde amtundu wa ultrashort. Udindo wa koyilo yamkuwa yamtunduwu imasinthidwa kuti isinthe inductance, yomwe ndiyabwino komanso yolimba.

5.Color code inductor

Mtundu wamagetsi inductor ndi inductor wokhala ndi inductance yokhazikika, ndipo kutulutsa kwake kumadziwika ndi mphete yamtundu ngati kukana.

6. Choke koyilo (kutsamwa koyilo)

Koyilo yomwe imalepheretsa kusinthasintha kwamakono kumatchedwa koyilo yokhotakhota, yomwe imagawidwa koyilo yamagetsi pafupipafupi komanso koyilo kotsika kwambiri.

7.Kusintha koyilo

Chosokeretsa ndikutulutsa kwa gawo loyang'ana pa TV. Chophikira chosokera chimafunikira kukhudzika kwakukulu, maginito yunifolomu, mtengo wapamwamba wa Q, kukula pang'ono ndi mtengo wotsika.

Zomwe zili pamwambazi ndikudziwitsidwa kwa SMT modzidzimutsa, ndikuyembekeza kukuthandizani pamtundu wina. Ndife ogulitsa inductor ochokera ku China - Getwell Electronics.
