Momwe Mungadziwire Ngati Chingwe cha Coax Ndi Choyipa (2 Njira Zowongolera)
Zamkatimu
M'nkhaniyi, ndikuphunzitsani momwe mungadziwire chingwe choipa cha coax mumphindi zochepa chabe.
Monga jack-of-all-trade, ndimagwiritsa ntchito njira zingapo kuti ndiwone momwe zingwe za coax zilili. Ndikuphunzitsani zabwino kuchokera mu bukhuli. Zingwe zowonongeka za coaxial zimabwera ndi zovuta zambiri, kuphatikiza koma osangokhala ndi ma siginecha obisika kapena kusalandila bwino kwa intaneti. Kupeza chifukwa chake n'kofunika kwambiri, osati kungoganizira chabe zochita.
Nthawi zambiri, muyenera kutsatira njira zingapo zosavuta kuti muwone ngati chingwe cha coax chili chabwino:
- Lumikizani choyesa chingwe cha DSS01 coax mu socket ya coax ndikudina batani kuti muyese.
- Chitani mayeso opitilira ndi ma multimeter apakompyuta.
- Mukhozanso kuyang'ana capacitance, kukana, ndi impedance ndi multimeter yamagetsi.
Ndikuuzani zambiri pansipa.
Momwe Mungadziwire Chingwe Cholakwika cha Coax
Ndikofunika kwambiri kukhazikitsa chikhalidwe cha chingwe chanu cha coaxial. Izi zidzakuthandizani kuzindikira vuto lenileni osati kungoganizira chabe. Mutha kugwiritsa ntchito njira zingapo kuti muwone ngati chingwe chanu cha coax ndichabwino kapena cholakwika. Ndipita mwatsatanetsatane za njira zina.
Njira 1: Kugwiritsa ntchito multimeter
Mutha kugwiritsa ntchito multimeter kuti muwone ngati chingwe chanu cha coax ndichabwino.
Multimeter imayesa kuthekera kwa magawo osiyanasiyana a chipangizo chamagetsi kudzera mu mawerengedwe ovuta ambiri.
Chitani mayeso otsatirawa pa chingwe cha coax:
Kupitiliza mayeso
Njira zotsatirazi zidzakuthandizani:
Khwerero 1: Ikani multimeter
Ikani chowunikira chofiira mu jack ndi chilembo V pafupi nacho, ndipo chofufuzira chakuda chimatsogolera mujeko wa COM.
Kenako ikani multimeter pamtengo wa "Ohm" parameter potembenuza kuyimba kosankha. Pomaliza, ping mawaya ofufuza; ngati ma multimeter akulira, pali kupitiliza pakati pa ma probe. Tsopano tiyeni tiyambe kuyesa chingwe cha coaxial.
Gawo 2: Yang'anani zolumikizira
Chingwe cha coaxial chilibe polarity.
Gwirani mawaya a probe pa zolumikizira ziwiri za coaxial. Ngati multimeter ikulira ndikuwerenga zosakwana 1 ohm, ndiye kuti pali kupitiliza mu chingwe chanu cha coax. Ngati kuwerenga kupitilira ohm imodzi, zolumikizira zanu ndizolakwika.
Khwerero 3: Yang'anani mawaya mkati mwa zolumikizira.
Gwirani zikhomo mkati mwa zolumikizira ziwiri kachiwiri. Kuwerenga kulikonse pansi pa ohm kumatanthauza kuti coax yanu ndiyabwino.
Kukaniza kuyesa
Apa, multimeter yamagetsi idzayesa mphamvu ya chishango cha chingwe cha coaxial ndi zigawo zina za chingwe. Chiwonetserocho chidzawonetsa mayankho / kuwerengera mu HMS (ma hectometer).
mwatsatane 1. Khazikitsani multimeter yanu kuti ikhale yotsutsa
mwatsatane 2. Ikani 50 ohm dummy load mu jack imodzi. Kenako gwirani chingwe chimodzi cha probe pamwamba pa cholumikizira china ndipo cholowera china kulowa mkati mwa soketi yomweyo - osanyamula katundu.
mwatsatane 3. Fananizani zotsatira zanu zokana ndi kulepheretsa mwadzina kwa chingwe chanu cha coax.
Kuwunika mphamvu
Apanso, gwiritsani ntchito multimeter yamagetsi kuti muwone mphamvu ya jekete ndi kondakitala wa chingwe cha coax. Kuwerengera kudzakhala mu picofarad (pf).
Ndondomeko: Ndi ma multimeter osinthidwa kukhala njira yoyezera kukana, gwirani malekezero onse a chingwe cha coaxial ndikuwona kuwerenga, komwe kudzakhala kochepa kwambiri - mu picometers.
Mayeso a Inductance
Mutha kugwiritsa ntchito ma multimeter apakompyuta kuti muwone kutulutsa kwa chishango ndi mzere wa chingwe cha coaxial. Poyesa inductance, mayankho a nanohenry (NH) ndi ohm (ohm) amakambidwa.
Zizindikiro za chingwe cha coax chowonongeka
Ma Rustic Connectors - Ngati dzimbiri likuwoneka kumapeto kwa chingwe chanu cha coax, chingwe cha coax chikhoza kukhala cholakwika.
Zomwe zikusowa zikuwonetsa vuto ndi chingwe cha coax.
Mtundu wobiriwira wa coaxial cable connectors umasonyezanso kuwonongeka.
Zolumikizira zofooka - Ngati mupotoza zolumikizira pa chingwe cha coaxial ndikuwona kuti ndizotayirira, zimawonongeka.
mawaya owonekera - Ngati zingwe mkati mwa chingwe cha coax zikuwonekera, zimawonongeka.
Chubu chapulasitiki chowonongeka (chomwe chimatchedwanso chishango cha rabara) - Ngati chishango cha rabara chawonongeka, chingwe chanu cha coax chikhoza kukhala cholakwika.
Chifukwa chake, ngati muwona chimodzi mwazizindikirozi, gwiritsani ntchito multimeter yamagetsi kuti mutsimikizire.
Taonani: Njira yoyamba yodziwira poyesa coax ndikuwona ngati alephera kale.
Zingwe za coaxial zimapangidwa ndi makampani osiyanasiyana, kotero kuti khalidwe lawo limasiyana kwambiri.
Njira 2: Kugwiritsa ntchito DSS01 Coax Cable Tester
Ndikupangira kugwiritsa ntchito DSS01 Coax Cable Tester kuti muwone zovuta ndi chingwe chanu cha coax. Ndi chida ichi, mumapewa kugula kapena kugwiritsa ntchito izi:
- Kulandila kwa chizindikiro chazovuta
- Kuthetsa mavuto kufala kwa chizindikiro
- Palibe multimeter yofunikira
- Coax Cable Tracking
- Kuyesa kopitilira - pa chingwe cha coaxial.
- Zomwe mukufunikira ndi DSS01 Coax Cable Tester!
Momwe mungagwiritsire ntchito DSS01 coaxial cable tester
Tsatirani izi zosavuta kuyesa chingwe chanu cha coax ndi choyesa cha DSS01:
mwatsatane 1. Lumikizani DSS01 Coax Cable Tester ku socket ya coax.
mwatsatane 2. Dinani batani la Mayeso. Zotsatira ziwoneka mumasekondi pang'ono.
DSS01 coaxial cable tester imapulumutsa nthawi ndi ndalama. Zomwe muyenera kudziwa ndikulumikiza socket ya coaxial ndi batani loyesa - ndizosavuta kugwiritsa ntchito.
Mavuto Odziwika Okhudza Zingwe Za Coaxial
Ndasankha zifukwa zinayi zazikulu za kulephera kwa chingwe cha coaxial. Apeweni kuti muwonetsetse moyo wautali komanso chitetezo chonse cha zingwe zanu za coax.
Matenthedwe kuwonongeka
Malo osungunuka a zingwe za coaxial ndi 150 ° F. Awa ndi malo osungunuka otsika. Chifukwa chake, zingwe za coaxial zimakhala pachiwopsezo cha kutentha kwambiri. (1)
malangizo: Kuti mupewe kuwonongeka kwa kutentha kwa chingwe cha coaxial, sungani kutali ndi magwero otentha. Ngati simutero, chishango cha rabara chikhoza kusungunuka, ndikukankhira zigawozo (mu chingwe) kuchoka pamalo ake.
Kuwonongeka kwa madzi
Zipangizo zamagetsi zambiri zimakhala zosatetezeka kumadzi. Zingwe za coaxial ndizosiyana. Mawaya amagetsi ndi zigawo zake zitha kulephera ngati zitakhala ndi madzi. Chifukwa chake, sungani chingwe cha coaxial kutali ndi madzi.
kupotoza kwa thupi
Chophimba cha chingwe cha coaxial ndi chosalimba. M'chimake wofewa wa chingwecho ukhoza kuthyoka ngati utaponyedwa, kugwiridwa mwankhanza, kapena kupindika mosasamala. Nthawi zonse yendetsani zingwe molunjika kutsogolo. Kupindika pang'ono kapena kink kungayambitse mkati mwa chingwe cha coax (kapena zigawo zamkati) kugwa.
Kuwonongeka kwa cholumikizira
Cholumikizira chowonongeka chingayambitse kulephera kwa chingwe cha coaxial.
Zingwezo zimakhala ndi zolumikizira kumapeto onse awiri. Zolumikizira zimasamutsa zambiri kuchokera kugwero kupita ku lina. Chifukwa chake, kusintha chilichonse mwa zolumikizira ziwirizi kumawononga ntchito ya chingwe cha coaxial. Mwamwayi, ngati mupeza mavuto, mutha kusintha zolumikizira m'malo mogula chingwe chatsopano. Ndipo, ndithudi, ichi ndi chifukwa chachikulu cha kulephera kwa zingwe za coaxial. (2)
Onani zina mwazolemba zathu pansipa.
- Momwe mungayang'anire chizindikiro cha chingwe cha coaxial ndi multimeter
- Chizindikiro chopitilira ma multimeter
- Momwe mungadulire waya wamagetsi
