Coil ea motlakase ea teraka ea ABS e laolang valve 4721950520

Coil e tloaelehileng

1. Coil e le 'ngoe ea lera

Khoele e nang le moalo o le mong e pota-potiloe ka har'a tube ea pampiri kapa skeleton ea bakelite e nang le lithapo tse sirelelitsoeng ka bonngoe. Joalo ka khoele ea antenna ea maqhubu seea-le-moeeng sa transistor.

2. Koele ea khekhe ea linotsi

Haeba sefofane sa khoele ea leqeba se sa bapane le sebaka se potolohang, empa se kopana ka lehlakoreng le itseng, mofuta ona oa coil o bitsoa coil ea mahe a linotši. Le makhetlo ao terata e kobehang ho ea pele le pele ha e bilika hang, e leng hangata ho bitsoang palo ea lintlha tse phuthang. Mokhoa oa ho tsoelipana le mahe a linotsi o na le melemo ea molumo o monyane, capacitance e nyane e ajoang le inductance e kholo. Likhoele tsa khekhe ea linotsi kaofela li entsoe ke mochini o tsoelipanang le khekhe ea linotsi. Ha ho na le lintlha tse ngata tse phuthang, matla a ajoang a fokotseha.

3. Ferrite core le tšepe phofo core coil

Inductance ea coil e amana le hore na ho na le mokokotlo oa makenete kapa che. Ho kenya ferrite core ka har'a coil ea moea ho ka eketsa inductance le ho ntlafatsa boleng ba coil.

4, koporo konokono coil

Coil ea mantlha ea koporo e sebelisoa haholo ho ultrashort wave range. Ho bonolo ebile ho tšoarella ho fetola inductance ka ho potoloha boemo ba mantlha ba koporo ho coil.

5, color code inductor

Inductor e nang le mebala e mebala-bala ke inductor e nang le inductance e tsitsitseng, 'me inductance ea eona e tšoauoa ka lesale la mebala joaloka mohanyetsi.

6, choke coil (khama)

Khoeli e thibelang ho feta ha metsi a chenchana e bitsoa choke coil, e ka aroloa ka khoele ea maqhubu a phahameng le ea maqhubu a tlase.

7. Coil e khelohang

Coil ea deflection ke mojaro oa sethala sa tlhahiso ea sekeno sa TV. Coil ea ho kheloha e hloka kutlo e phahameng ea ho kheloha, matla a khoheli a ts'oanang, boleng bo phahameng ba Q, boholo bo nyane le theko e tlase.

tshebetso

Ketso ea ho khopama

Matla a elektromotive a ikemetseng ka har'a coil ea inductance coil e lula e hanyetsa phetoho ea hona joale ea khoele. Coil inductance e na le phello e thibelang ho AC hona joale, 'me boholo ba phello e thibelang e bitsoa inductance xl,' me unit ke ohm. Kamano ea eona le inductance L le AC frequency F ke xl=2πfl. Li-inductors li ka aroloa haholo-holo ka li-coil tsa maqhubu a phahameng le li-coke coke tse fokolang maqhubu.

Tokiso le khetho ea makhetlo

Potoloho ea tokiso ea lc e ka thehoa ka ho hokahanya coil ea inductance le capacitor ka ho tšoana. Ke hore, maqhubu a tlhaho a oscillation f0 ea potoloho a lekana le frequency f ea lets'oao le sa fetoheng, ka hona, inductive reactance le capacitive reactance ea potoloho le tsona lia lekana, kahoo matla a motlakase a oscillates ho ea pele le pele ho inductance. capacitance, e leng ketsahalo ea resonance ea potoloho ea lc. Ha resonance, inductive reactance le capacitive reactance ea potoloho lia lekana ebile li fapane, 'me ts'ebetso ea inductive ea kakaretso ea loop current ke e nyenyane ka ho fetisisa' me ea hona joale ke e kholo ka ho fetisisa (e bua ka letšoao la AC le f = "F0"). lc resonant circuit e na le mosebetsi oa ho khetha maqhubu, a ka khethang letšoao la AC le itseng
