Mphamvu ya khungu pa chingwe coaxial

Chingwe coaxial ndi mtundu wa waya wamagetsi ndi chingwe chotumizira chizindikiro, nthawi zambiri chimapangidwa ndi zigawo zinayi za zinthu: wosanjikiza wamkati ndi waya wamkuwa wa conductive, ndipo waya wakunja wa waya wazunguliridwa ndi pulasitiki (yomwe imagwiritsidwa ntchito ngati insulator kapena dielectric). ). Palinso mauna opyapyala azinthu zopangira (nthawi zambiri zamkuwa kapena aloyi) kunja kwa insulator, ndipo gawo lakunja la zinthu zomwe zimayendetsa zimagwiritsidwa ntchito ngati khungu lakunja, monga momwe tawonetsera pa Chithunzi 1, Chithunzi 2 chikuwonetsa gawo la coaxial. chingwe.

Zingwe za coaxial zimagwiritsidwa ntchito potumiza ma siginecha apamwamba kwambiri ndipo zimakhala ndi luso loletsa kusokoneza chifukwa cha mawonekedwe ake apadera. Monga gawo lofunikira kwambiri pamakina amakono olankhulirana, ndi mtsempha wotumizira mazizindikiro apamwamba kwambiri; Pakati pawo, kondakitala wapakati samanyamula mphamvu yamagetsi, komanso amatsimikizira momwe kufalikira kwazizindikiro kumayendera komanso kukhazikika, ndipo ndi gawo lofunikira pakufalitsa ma siginecha.

Mfundo yogwirira ntchito:

Zingwe za coaxial zimayenda mosinthasintha m'malo molunjika, kutanthauza kuti pali zosinthika zingapo zomwe zimayendera pasekondi iliyonse.

Ngati waya wokhazikika amagwiritsidwa ntchito potumiza ma frequency apamwamba, waya wamtundu uwu udzakhala ngati mlongoti womwe umatulutsa ma wayilesi kunja, zomwe zimapangitsa kutayika kwa mphamvu yazizindikiro komanso kuchepa kwa mphamvu ya siginecha yolandilidwa.

Mapangidwe a zingwe za coaxial ndikuthetsa vutoli. Wailesi yomwe imatulutsidwa ndi waya wapakati imasiyanitsidwa ndi ma mesh conductive wosanjikiza, omwe amatha kuwongolera wailesi yotulutsidwa kudzera pakuyika pansi.

Gulu:

Kutengera ndi zinthu zopangira ndi njira, nthawi zambiri pamakhala magulu awa:

● Kondakitala wa Monofilament Solid:

Kawirikawiri amapangidwa ndi waya umodzi wolimba wamkuwa kapena aluminiyamu;

Amapereka mphamvu zamagetsi ndipo nthawi zambiri amagwiritsidwa ntchito pochepetsa mafupipafupi kapena mtunda wautali wa chingwe

● Kondakitala Wotsekeredwa:

Ndi mawaya angapo ang'onoang'ono opotoka;

Zosinthika komanso zosinthika kuposa ma conductor olimba, oyenera kugwiritsa ntchito mafoni kapena osintha pafupipafupi.

● Copper-clad Steel (CCS) :

Chitsulo chachitsulo chimapereka mphamvu ndi kukhazikika, pamene mkuwa wa mkuwa umapereka zinthu zofunikira zamagetsi;

Nthawi zambiri amagwiritsidwa ntchito pazochitika zomwe mphamvu zamakina zimafunikira.

● Mkuwa Wopindidwa Siliva:

Waya wamkuwa wokutidwa ndi siliva wosanjikiza, womwe ukhoza kupititsa patsogolo ma conductivity ndi ma frequency a conductor.

Nthawi zambiri amagwiritsidwa ntchito pafupipafupi, kulondola kwambiri kapena zofunikira zankhondo.

● Cadmium Copper alloy:

Aloyi kondakitala kwa offshore kapena nkhanza chilengedwe ntchito kumene kukana dzimbiri kumafunika;

Chidule chachidule cha nthano-Conductor&Braid Material monga zikuwonekera pachithunzi 3.

Khungu zotsatira

Zotsatira za khungu, zomwe zimadziwikanso kuti khungu, zimachitika pamene njira yosinthira idutsa pa kondakitala. Chifukwa cha kulowetsedwa, pafupi kwambiri ndi pamwamba pamtunda wa conductor, ndi deser kugawa ma electron.

Zotsatira zapakhungu ndizomwe zimachitika pakugawa kosagwirizana kwa AC pano mkati mwa kondakita. Pamene mafupipafupi akuwonjezeka, zamakono zimakonda kuyenda pamwamba pa conductor. Pa ma frequency a microwave, izi zimatchulidwa makamaka, zomwe zimapangitsa kuti pakhale kachulukidwe kakang'ono kwambiri pamwamba pa kondakita wapakati wa chingwe cha coaxial kuposa mkati.

△ Khungu lakhungu limakhudza chingwe cha coaxial muzinthu izi:

① Kuchulukitsa kukana ndi kutayika - Chifukwa chapano makamaka chimayenda pamtunda, malo onse oyendetsera bwino amachepetsedwa, kupangitsa kuti woyendetsa wapakati wa chingwe cha coaxial apangitse kukana kwakukulu, potero kumawonjezera kutayika.

② Kutentha - Zomwe zimayambitsidwa ndi chizindikiro chapamwamba kwambiri zimakhazikika pamtunda, zomwe zimapangitsa kuti pakhale kutentha kwambiri, motero kumawonjezera kutentha kwa chingwe ndikukhudza kukhazikika ndi kudalirika kwa chizindikiro.

③ Kusankha kwazinthu - Popanga chingwe cha coaxial, kuwongolera kwazinthu zapakati kondakitala kuyenera kuganiziridwa. Zida zopangira ma conductivity apamwamba monga plating yamkuwa ya siliva zimatha kuchepetsa kukana ndikuchepetsa kutayika.

△Kuchepetsa zovuta zapakhungu, njira zothanirana ndi zovuta zapakhungu ndizo:

① Kukhathamiritsa kwazinthu - kusankha zida zapamwamba kuti muchepetse kutayika. Mwachitsanzo, pogwiritsa ntchito siliva wokutidwa kondakitala mkuwa, wosanjikiza siliva angapereke madutsidwe mkulu, ndipo chifukwa cha zotsatira khungu, makulidwe a siliva amangofunika micrometers ochepa.

② Kapangidwe ka Kondakitala - Kuwongolera kapangidwe ka ma conductor, monga kugwiritsa ntchito ma conductor otsekeka, kumatha kukulitsa malo ndikuchepetsa khungu.

③ Dongosolo Lozizira - Pazogwiritsa ntchito pafupipafupi kwambiri, gwiritsani ntchito makina ozizirira abwino kuti mupewe kutenthedwa.

④ Chingwe Chokhazikika - Sinthani mawonekedwe a chingwe kutengera zomwe mukufuna, poganizira zinthu zingapo monga pafupipafupi, kuchuluka kwa mphamvu, ndi mtunda wotumizira.

Ponseponse, kumvetsetsa ndikuwongolera mawonekedwe akhungu ndikofunikira pakuwonetsetsa kuti kufalikira kwa ma frequency apamwamba kwambirizingwe za coaxial . Kupyolera mu kupanga mwanzeru komanso kugwiritsa ntchito zipangizo zapamwamba kwambiri, ma coaxial transmission mizere amatha kugwira ntchito bwino kwambiri, motero amathandizira zosowa zathu zoyankhulirana zomwe zikukula mofulumira. Ndizo zisankho zomwe zimatsimikizira kuti chizindikiro chilichonse, kuchokera ku mauthenga opanda zingwe pansi kupita ku ma satellite, amatha kufalitsidwa momveka bwino komanso modalirika m'madera ovuta komanso ovuta.
