I-Air Core Coil Ukuqhathanisa: Thola Ukufana Okuphelele Kwezinto Zakho Zogesi

Ukuqonda Ikhoyili ye-air cores

Izisekelo ze Ikhoyili ye-air cores

Ikhoyili ye-Air-core iyisisetshenziswa esiyisisekelo ku-elekthronikhi esisebenza ngokusekelwe endaweni kazibuthe ebangelwa amandla kagesi, kuyilapho ngaphandle kwe-ferromagnetic core. Lesi sinqumo sokuklama sibalulekile kuzici zabo nokusebenza kwazo. Intambo exhumayo futhi ejikajikayo izungeze kanye neshubhu elingenalutho eliwumgogodla womoya (noma elingewona uzibuthe) ukuphela kokwakhiwa kwalawa makhoyili okuphumela ekungeneni okumsulwa kakhulu kanye nokuzwakalayo ngenxa yalokhu kuncipha okuphawulekayo kokulahlekelwa okuphakathi kanye nokungewona umugqa kusebenze kumongo. Ngokukhetha igeji yocingo, ukuminyana okumazombezombe kanye nobubanzi bekhoyili ungalungisa i- Ikhoyili ye-air coreukuhlangabezana ne-inductance ethile ngemvamisa ethile, ukwenza Ikhoyili ye-air coreithuluzi likanjiniyela we-sa design lisebenza ngezindlela eziningi.

Izinzuzo Zokusebenzisa Ikhoyili ye-air cores

Ikhoyili ye-air cores inikeza izinzuzo ezimbalwa ezivumelana nayo ekusetshenzisweni okuningi. Okokuqala, ukulahlekelwa okuyinhloko kuphansi kakhulu ngakho-ke akukho lutho olungadonsa futhi luhlakaze amandla ngendlela yokushisa, okuyinzuzo enkulu kumafrikhwensi aphezulu. Ikhoyili ye-air coreAma-s nawo alayini ngaphezu kwezinhlobo eziningi zezici zokusebenza njengoba engenawo umongo kazibuthe wokusuthisa ama-inductors amaphakathi ahlinzeka ngamavelu azinzile we-inductance ngisho nangaphansi kwezimo eziphakeme zamanje. Lokhu kulayini, kuhlangene nokuntuleka kwe-hysteresis kanye nokulahlekelwa kwamanje kwe-eddy, kubangela ukuthi la makhoyili anikeze ukusebenza okuphezulu kakhulu ezinhlelweni ze-RF lapho ikhwalithi yesiginali iyisidingo. Lezi zinzuzo zivame ukuhlula usayizi omkhulu uma kuqhathaniswa nama-ferrite noma ama-iron-cores ekusetshenzisweni kwefrikhwensi ephezulu.

Izicelo ku-Electronics

I - kernel helix yomoya ithola amaloshini ahlukahlukene kuwo wonke abakhiqizi bemishini kagesi , ngenxa yesici sabo esiyingqayizivele . Izinsiza zakho zivame kakhulu kuhlelo lokusebenza lwefrikhwensi engenawaya ( RF ) , ezihlanganisa inzwa , isihlungi se- RF , nesekhethi yokushuna , lapho umthengisi wabo we- Q ephezulu isici esishodayo esiphansi sibalulekile .

Hte ukuhlukahluka kwe Ikhoyili ye-air cores idlulela kumishini yocwaningo lwesayensi, lapho ukunemba kanye nokuhlanekezela okuncane kwesignali kuyadingeka.

Leli thebula libonisa ukuthi izinhlelo zokusebenza ezihlukene zizuza kanjani ezintweni ezithile zekhoyili, njenge-Q factor ephezulu yamasekhethi e-RF noma ukulahleka kwesignali ephansi kwemishini yomsindo.

Ukukhetha Kwesokudla Ikhoyili ye-air core

Amapharamitha Abalulekile Okufanele Acatshangelwe

Ukunquma nge Ikhoyili ye-air coreukusetshenziswa ku-electronics yakho kuwumsebenzi okufanele ubhekwe njengento ebaluleke kakhulu njengoba kunezinombolo ezibalulekile ezizobonisa ukuthi ikhoyili izosebenza kanjani esicelweni sakho. I-inductance, evezwa ku-Henries (H), ibaluleke kakhulu ngoba ikhombisa ukuthi ingakanani isitoreji esinamandla esingagcinwa ikhoyili. I-inductance eyengeziwe ilingana nokugcinwa kwamandla amaningi kanye nomzimba omkhulu. Esinye isici esibalulekile imvamisa yokusebenza; kumafrikhwensi aphezulu, Ikhoyili ye-air cores ngokuvamile asetshenziswa ngenxa yekhono lawo eliphansi le-parasitic. Ukumelana nekhoyili nokubamba amandla kuthinteka ububanzi (Igeji) yocingo. Okokugcina ubukhulu bangempela bekhoyili; kufanele ilingane ocingweni futhi ihlangabezane nezici zokungeniswa nezici zokumelana..

Ukuqhathanisa Okuhlukile Ikhoyili ye-air cores

Ukuqhathanisa Okuhlukile Ikhoyili ye-air cores Ukusiza enqubweni yokukhetha, ithebula elilandelayo liqhathanisa okuhlukahlukene Ikhoyili ye-air cores ngokusekelwe kuzibaluli zabo eziyinhloko:

Amacebiso Asebenzayo Okukhethwa Kwekhoyili

Ukukhetha okuhle kakhulu Ikhoyili ye-air coreumbuzo ongaphezu kokumane uqhathanise imininingwane - ukuthi yini okufanele isetshenziselwe izindaba, kakhulu! Cabangela indawo ikhoyili yakho ezochayeka kuyo (ukushisa, amakhaza, nokucindezeleka komshini) futhi uyivumele ukuba ibekezelele uvivinyo lwesikhathi. Bheka ukuthi asebenza kalula kangakanani ngomklamo wakho, njengoba amanye amakhoyili adinga izingxenye ezengeziwe noma umumo ukuze asebenze ngendlela eklanywe ngayo. Okokugcina, cabangela ukulinganisa okuzayo nokutholakala kubathengisi. Ukuba nekhoyili engekho eshalofini, noma okungenani engakwazi ukuguquleka eshalofini ngomzamo omncane wokuklama, kuqinisekisa ukukhiqizwa okushelelayo kanye noshintsho olulula esikhathini esizayo lapho kudingeka ukuthuthukiswa noma ukulungiswa.

Ukuklama Okwakho Ikhoyili ye-air core

Ukubala amapharamitha wekhoyili

Amapharamitha we- Ikhoyili ye-air coreimininingwane evame ukuba yindawo yokudlulisela eyindida ukuqondwa uma uklama ikhoyili yokungenisa eyingqikithi yomoya. Lezi yi-inductance (L), i-wire gauge (AWG), ububanzi bekhoyili (D) kanye nenani lokujika (N). Okubalulekile yi-inductance enquma ukuthi ikhoyili ingagcina amandla angakanani. Kuya kububanzi bekhoyili kanye nenani lokuphenduka; ukuphakama kwe-diameter kanye nokuphenduka okuningi, i-inductance iphezulu. Usayizi wentambo ushintsha ukumelana nekhoyili kanye nomthamo wamanje wokuthwala ukuze kube inkinga yosayizi uma iqhathaniswa namandla. Ukubalwa kwalezi zinhlaka kufanele kube okunembile ukuze kuhlinzekwe ikhoyili eklanyelwe eklanyelwe ukusetshenziswa kwe-elekthronikhi okukhulunywa ngayo.
