Mokhoa oa ho bolela haeba Cable ea Coax e fosahetse (Tsela ea Mekhoa e 2)
Tse ka hare
Sehloohong sena, ke tla u ruta mokhoa oa ho khetholla mohala o mobe oa coax ka metsotso e seng mekae feela.
Joaloka jack-of-all-trades, ke sebelisa maqheka a 'maloa ho lekola boemo ba likhoele tsa coax. Ke tla u ruta se molemohali ho tsoa ho tataiso ena. Lithapo tsa coaxial tse senyehileng li tla le mathata a mangata, ho kenyeletsoa empa a sa felle feela ho mats'oao a patiloeng kapa kamohelo e mpe ea inthanete. Ho fumana sesosa sa motheo ke habohlokoa, eseng feela menahano ea ho etsa liqeto.
Ka kakaretso, o hloka ho latela mehato e 'maloa e bonolo ho fumana hore na thapo ea coax e ntle:
- Hokela mochine oa cable oa DSS01 oa coax ka har'a sokete ea coax ebe o tobetsa konopo ho e leka.
- Etsa tlhahlobo ea ho tsoelapele ka multimeter ea elektronike.
- U ka boela ua lekola bokhoni, ho hanyetsa, le ho se sebetse ka multimeter ea elektroniki.
Ke tla u bolella haholoanyane ka tlase.
Mokhoa oa ho hlahlobisisa Cable ea Coax e Fosahetseng
Ho bohlokoa haholo ho theha boemo ba thapo ea hau ea coaxial. Sena se tla u thusa ho lemoha bothata ba 'nete, u se ke ua inahanela. U ka sebelisa mekhoa e mengata ho lekola hore na thapo ea hau ea coax e ntle kapa e mpe. Ke tla kena ka ho qaqileng ka tse ling tsa mekhoa ena.
Mokhoa oa 1: Ho sebelisa multimeter
U ka sebelisa multimeter ho lekola hore na thapo ea hau ea coax e fosahetse.
Multimeter e lekola bokhoni ba likarolo tse fapaneng tsa sesebelisoa sa elektroniki ka lipalo tse ngata tse rarahaneng.
Etsa liteko tse latelang ho thapo ea coax:
Teko ea ho tsoela pele
Mehato e latelang e tla u thusa:
Mohato oa 1: Kenya multimeter
Kenya motsoako o mofubelu ka har'a jeke e nang le V haufi le eona 'me u etelle pele ka har'a jack ea COM.
Ebe u beha multimeter ho boleng ba "Ohm" parameter ka ho potoloha mohala oa khetho. Qetellong, ping lithapo probe; haeba multimeter e lla, ho na le tsoelo-pele pakeng tsa li-probes. Joale ha re qaleng ho lekola thapo ea coaxial.
Mohato oa 2: Sheba lihokelo
Coaxial cable ha e na polarity.
Tšoara lithapo tsa probe holim'a lihokelo tse peli tsa coaxial cable. Haeba multimeter e lla 'me e bala ka tlase ho 1 ohm, joale ho na le tsoelo-pele ho cable ea hau ea coax. Haeba 'malo o feta ohm e le' ngoe, likhokahano tsa hau li na le phoso.
Mohato oa 3: Hlahloba lithapo ka hare ho lihokelo.
Tšoara lithakhisa ka hare ho lihokelo tse peli hape. Ho bala hofe kapa hofe ka tlase ho ohm e le 'ngoe ho bolela hore coax ea hau e ntle.
Teko ea ho hanyetsa
Mona, multimeter ea elektronike e tla leka motlakase oa coaxial cable shield le likarolo tse ling tsa cable. Pontsho e tla bontsha dikarabo/ho bala ho HMS (hectometers).
hata 1. Beha multimeter ea hau ho mokhoa oa ho hanyetsa
hata 2. Kenya 50 ohm dummy load ka jekong e le 'ngoe. Ebe u ama ntlha e le 'ngoe ea probe holim'a sehokelo se seng' me e 'ngoe u lebise ka hare ho sokete e le 'ngoe-ha ho na moroalo oa dummy.
hata 3. Bapisa liphetho tsa hau tsa khanyetso le "impedance" ea lebitso la thapo ea hau ea coax.
Tlhahlobo ea bokhoni
Hape, sebelisa multimeter ea elektronike ho hlahloba bokhoni ba baki le conductor ea cable ea coax. Lipalo li tla ba ka picofarads (pf).
Tsamaiso: Ka multimeter e fetoletsoeng ho mokhoa oa ho lekanya ho hanyetsa, ama li-lead lintlheng tse peli tsa mohala oa coaxial 'me u hlokomele ho bala, e tla ba e nyenyane haholo - ka picometers.
Teko ea inductance
U ka sebelisa multimeter ea elektronike ho hlahloba inductance ea thebe le mohala oa mohala oa coaxial. Ha ho hlahlojoa inductance, ho buisanoa ka tharollo ea nanohenry (NH) le ohm (ohm).
Matšoao a thapo ea coax e senyehileng
Lihokelo tsa Rustic - Haeba mafome a hlaha lipheletsong tsa thapo ea hau ea coax, thapo ea coax e kanna ea fokola.
Likarolo tse sieo li bontša bothata ka mohala oa coax.
'Mala o motala oa li-coaxial cable connectors o boetse o bontša tšenyo.
Lihokelo tse fokolang - Haeba u sotha li-connectors holim'a mohala oa coaxial 'me u ikutloa eka li hlephile, li senyehile.
mehala e pepeneneng - Haeba likhoele tse ka hare ho thapo ea coax li bonahala, e senyehile.
Tube ea polasetiki e senyehileng (eo hape e bitsoang thebe ea rabara) - Haeba thebe ea rabara e senyehile, thapo ea hau ea coax e kanna ea ba le sekoli.
Kahoo, haeba u hlokomela leha e le efe ea matšoao ana, sebelisa multimeter ea elektronike ho netefatsa.
Ela hloko: Mokhoa oa pele oa ho lemoha oa ho hlahloba coax ke ho bona hore na ba se ba hlolehile.
Lithapo tsa coaxial li entsoe ke lik'hamphani tse ngata tse fapaneng, kahoo boleng ba tsona bo fapana haholo.
Mokhoa oa 2: Ho sebelisa DSS01 Coax Cable Tester
Ke khothaletsa ho sebelisa DSS01 Coax Cable Tester ho hlahloba mathata ka cable ea hau ea coax. Ka sesebelisoa sena, u qoba ho reka kapa ho sebelisa tse latelang:
- Kamohelo ea lets'oao la ho rarolla mathata
- Phetiso ea lets'oao la bothata
- Ha ho na multimeter e hlokahalang
- Coax Cable Tracking
- Teko ea ho tsoela pele - ka mohala oa coaxial.
- Seo u se hlokang feela ke DSS01 Coax Cable Tester!
Mokhoa oa ho sebelisa DSS01 coaxial cable tester
Latela mehato ena e bonolo ho leka thapo ea hau ea coax ka tester ea DSS01:
hata 1. Hokela DSS01 Coax Cable Tester ho sokete ea coax.
hata 2. Tobetsa konopo ea Test. Liphetho li tla hlaha ka mor'a metsotsoana e seng mekae.
DSS01 coaxial cable tester e boloka nako le chelete. Sohle seo u hlokang ho se tseba ke mokhoa oa ho hokahanya sokete ea coaxial le konopo ea teko - ho bonolo ho e sebelisa.
Mathata a Tloaelehileng a Amang Lithapo tsa Coaxial
Ke khethile lisosa tse 'nè tse ka sehloohong tsa ho hlōleha ha cable ea coaxial. Li qobe ho netefatsa bophelo bo bolelele le polokeho ka kakaretso ea likhoele tsa hau tsa coax.
Tšenyo ea mocheso
Sebaka se qhibilihang sa lithapo tsa coaxial ke 150°F. Ena ke sebaka se batlang se le tlase se qhibilihang. Kahoo, lithapo tsa coaxial li kotsing ea mocheso o phahameng. (1)
malebela: Ho qoba tšenyo ea mocheso ho thapo ea coaxial, e boloke hole le mehloli ea mocheso. Haeba u sa etse joalo, thebe ea rabara e ka 'na ea qhibiliha, ea sutumelletsa likarolo (ka cable) ho tloha sebakeng seo.
Tšenyo ea metsi
Lisebelisoa tse ngata tsa motlakase li kotsing ea metsi. Lithapo tsa coaxial le tsona li joalo. Lithapo tsa motlakase le likaroloana li ka 'na tsa hloleha ha li le metsing. Ka hona, boloka thapo ea coaxial hole le metsi.
ho sotha mmele
Thebe ea mohala oa coaxial e senyeha habonolo. Mohatla o bonojoana oa thapo o ka robeha haeba o ka lahleloa, o tšoaroa ka thata kapa o kobeha ka bohlasoa. Tsamaisa lithapo ka ho toba pele. Koba e nyenyane kapa kink e ka etsa hore li-innards tsa cable ea coax (kapa likarolo tse ka hare) li oe.
Tšenyo ea sehokelo
Sehokelo se senyehileng se ka lebisa ho hloleheng ha mohala oa coaxial.
Lithapo li na le likhokahano lipheletsong ka bobeli. Lihokelo li fetisetsa tlhahisoleseding ho tloha mohloling o mong ho ea ho o mong. Ka hona, ho fetola e 'ngoe ea lihokelo tse peli ho theola tšebetso ea thapo ea coaxial. Ka lehlohonolo, haeba u fumana mathata, u ka nka sebaka sa likhokahano sebakeng sa ho reka thapo e ncha. 'Me, ha e le hantle, lena ke lona lebaka le ka sehloohong la ho hlōleha ha likhoele tsa coaxial. (2)
Sheba tse ling tsa lingoliloeng tsa rona tse ka tlase.
- Mokhoa oa ho hlahloba lets'oao la thapo ea coaxial ka multimeter
